Sense 6.0 official game boost method
HTC added High Performance Mode in it's Sense 6.0 update, which is acts like an official form of game boost, now locked users can enjoy the full speed of the s600 as well
Higher Performance Mode (HPM) in Stock Sense 6 software, hidden in developer options (Screenshots)
- Go to your HTC One (M8) settings menu and scroll to the very bottom. Select "About" and open the "Software Information" menu.
- Tap on the "Build Number" several times until you get a message confirming that "you're now a developer".
- The developer options menu should now appear in your settings list. Go ahead and open it. Note that this section contains settings that should not be modified unless necessary. Doing so may make your phone behave in unexpected ways. Proceed at your own risk from now on.
- The fifth option in the list should be labeled "High Performance Mode". Enable it by marking the tick to the right. Tap again to disable the mode when it isn't required.

This will force the CPU into higher frequencies, delay throttling and prevent stalls/fps dips from any affected app (try it with Ripetide GP2)
Always remember that this boost will take a heavy tole on the battery and thermals, so remember to disable HPM when you are done gaming

Fast version of this guide and simple solution:
For new comers, this section should be enough
Facts: Gaming on the HTC One can be negatively affected by two factors, CPU/GPU thermal throttling (down) and the inability to boost the CPU in tilt /sensor controlled games
Example: By default Asphalt 8 in tilt controls will fluctuates between smooth and laggy, with touch controls it's smooth until the GPU throttles down after 15 minutes and then it becomes laggy, with the following solution the HTC One will run this game above 30fps locked even with max graphics effects
Scripts: Prevent CPU / GPU throttling and Boost the CPU | last updated 11-12-2013
Simply use my Boost script before your start your favorite game, it will insure using the max CPU and GPU speed during your game session, once you are done gaming unBoost and the device returns to it's stock state
The only requirement is acquiring root

Comprehensive HTC One gaming performance guide and multiple solutions:
The HTC One runs heavy 3D games like Modern Combat 4 in full visual quality, native 1080p resolution and remains above 30fps, equally the HTC One Adreno 320 GPU beats the iPad 4 GPU in native performance, unfortunately you will be surprised when your powerful HTC One suddenly drops smooth frame rate after some time of gameplay
This because like most Snapdragon 4 pro and 600 devices, Qualcomm throttles the CPU clocks when it hits a select temperature target, this is done to both protect the device, reduce overheating and extend battery life, unfortunately the target temperature is entirely up to the OEM and these targets vary greatly between quad core krait devices, to make matters worse certain OEMs choose to throttle the Adreno 320 GPU as well, the GPU is the most important gaming hardware in your device, currently we have abundance of CPU power but we can never have enough GPU power, this is why dropping the GPU clocks will directly drop your gaming performance, check this post on how different device builders throttle their Snapdragons
The HTC One by default throttles the CPU when it reaches 57c but it also throttles the GPU with CPU when the battery arrives at 40c (probably to safeguard the built-in battery), it drops from 400mhz to 320mhz, after 20 minutes or so of gameplay the GPU will slowdown, throttling the CPU at 57c is fine but the 40c battery GPU threshold is simply too soon, this throttling is just preservative especially since the GPU is already under clocked at 400mhz, equally this device metal shell actually acts a heatsink and gets rids of it's heat quite well
The other part of this gaming equation is CPU speed, by default the speedy quad core favors medium CPU frequencies for average jobs and will ramp up fairly well when more is needed, this is all controlled by the CPU governor, however there are certain heavy games which still fail to call full CPU speed or maintain it, particularly if a game relies on tilt or sensor controls, like Asphalt 8 or Ripetide GP 2, for such games you will need to increase the CPU aggressiveness
In conclusion, if we want to have the full gaming performance expected from our HTC One, we will have to disable GPU throttling and boost the CPU
This guide consists of three parts:
. Part I: GPU Throttling
. Part II: CPU Boost
. Part III: More performance tricks (future proofing)
----------------------------------------------------------------------------
Part I: GPU Throttling
Reminder the following tips will use the device to its potential and therefore will abuse the battery life, so try to be moderate and don't over use the device at high temps
General tips for stock non rooted users
In order to control throttling on your HTC One without root, you have little choice but to prevent your device from heating and so delay throttling, consider the following tips:
- Never play games on the charger otherwise this means instant overheat
- Covers and cases this might be the most important tip, the metalic back plate is linked to the CPU and meant as a heatsink by design, so covers especially hard covers will prevent the metal back plate from releasing heat, choose a cover which doesn't trap the heat, i found the worst is polycarbonate hard shells, meanwhile TPU did conduct heat a little better, finally the official double flip case was best for me since it's rubber, has many exposed areas and the device a little relaxed
- Thankfully the power saver mode doesn't reduce the GPU clock only the CPU is dropped to 1134mhz, so you can rely on the power saver mode to delay throttling
- Auto Sync and background activity will contribute to processor usage and heat increase, so disable auto sync and kill background processes
- Screen brightness is also be a contributor to temperatures as well, so don't go for the max
- Ambient temperature your ambient temperature will affect the temps of your device, so if you are in a hot environment throttling will come sooner than later
Unfortunately at 40c battery there isn't much we can do, when gaming your device will reach this temp sooner or later, this is why rooting and custom recovery gives us much greater control and allows us to unleash gaming on this device
Prevent CPU / GPU throttling and Boost the CPU - requires root
You can simply lock the Max CPU and GPU speeds using the gaming boost scripts described in the second part of this guide, the Boost script will set the Max CPU and GPU clock to read only preventing the system from throttling them down, once you unBoost the device returns to it's stock state
- Simply download my HTC One Simple Gaming Boost scripts and follow the tutorial for a one click solution
Remember to always unBoost once you are done gaming to allow the phone to cool down
Disable GPU throttling - requires root and custom recovery
You can also disable GPU throttling all together or configure throttling on stock kernel thanks to jerrylzy's work
- Download the Stock no gpu patch (stock_nogpu.zip) and flash it from custom recovery
This will keep the CPU throttling at 57c but disables GPU throttling, your games will no longer lag suddenly once the battery reaches 40c, you can also use the performance patch which further delays CPU throttling
Alternatively you can read through the tutorial and customize the thermald file for your liking
Custom kernels with built-in thermal control - requires root and custom recovery
If your device is Unlocked and Rooted, you can flash a custom kernel which has thermal controls, for example the ElementalX Kernel replaces the HTC thermal driver with it's own and gives us control during the kernel installation process, as explained by flar2 the kernel developer
Thermal Control
I've added kernel based thermal control and throttling. HTC's thermald is very aggressive and throttles the CPU frequency pretty much anytime you use all four processors. This kernel based implementation allow better performance while still protecting your phone from overheating. There are three levels of thermal control, which can be chosen in the installer or changed in /etc/elementalx.conf. The default option is recommended. With the run cool option, your CPU will run about 5C cooler than default while under heavy load. With the run hot option, the CPU will run about 5C warmer than default under heavy load.

There is no throttling of the GPU.
The CPU throttling kicks in when it hits certain temperatures. The first level throttles to 1728 if you're overclocking (there is no change if you are at stock freqs or lower), the second level throttles to 1350, the third level throttles to 918, the fourth to 384. It is unlikely that you will ever get to the fourth throttling level even in an extremely hot climate.

The Snapdragon 600 GPU is able to achieve 450mhz, in fact it's the stock clock on the SGS4, ElementalX OCs the GPU to 450mhz by default, the default throttling behavior for this kernel starts at 63c which is massively better than HTC's 40c and thankfully it only affects the CPU
By the way the default throttling files on the s600 SGS4 will not start to throttle before 85c and it doesn't drop the GPU either, this should give a good idea how held back the s600 is on the HTC One
I found the following configuration the most optimal when using ElementalX
- Don't go above the stock 1728mhz in AROMA (kernel installer), for gaming we really don't need more so lets not OC to keep the heat down, in fact most games will not use more than 2 to 3 CPU cores, also if you don't lock it from the installer it will never stick, you can even go with 1533mhz lock for further heat reduction
- Select your throttling temps from AROMA, thankfully this only affects the CPU and not the GPU, at default throttling it begins at 63c, with run hot it starts at 66c, run cool is 58c and run extra cool is 54c, you will have to find the sweet spot for your device, more info here
- Select GPU 450mhz from AROMA, we didn't OC the CPU in order to have thermal room for GPU OC
- You can even go with power saver mode which reduces CPU to 1134mhz, in most games you notice any drop at these CPU clocks, GPU will remain at max clock and heat will be further delayed

Part II: CPU Boost
CPU Boost: Tweaking CPU governor for Games in need of single threaded top speed (ex: Asphalt 8 & Ripetide GP2 which suffer from performance dips unless the CPU is boosted)
For certain games you might have unexplained bad performance, this means the game is not really optimized for the device since the default ondemand CPU governor is usually pretty good in extracting performance, some games also suffer if they rely on tilt controls since without screen interaction the CPU fails to ramp up, for such issues you can boost the ondemand CPU governor, a better alternative to the performance governor (which would lock the cpu at high clocks causing heat/drain)
Note for HTC stock Kitkat kernel you will need to use performance CPU governor since ondemand boost no longer works
These tweaks require root access
More info about games in need of CPU governor boost>>
Optimize the stock CPU Governor for more aggressive behavior using a one click script (Free)
- Simply download my HTC One Simple Gaming Boost scripts and follow the tutorial for a one click solution
Remember to always unBoost once you are done gaming to allow the phone to cool down
How to Manually Optimize the stock CPU Governor for more aggressive behavior (Free)
- Download a free app like Tickster MOD
- Go to the General tab scroll down to CPU governor control section and click the Governor Control button, scrolldown to Up_Threshold* and lower it to 50
- From the General tab I/O control section, change the Scheduler to deadline and raise the Read Ahead Buffer Size to 1024 or 2048
- You can Set On Boot from the app's main menu
*Up_Threshold: This is the main load threshold, reducing this value from the stock 90 will make the CPU more aggressive, recommended for gaming: 50
This no longer work for HTC stock Kitkat kernel, instead switch to performance CPU governor as described below
How to Manually Switch your CPU governors (Free)
- Download a free app like Tickster MOD
- Go to the General tab scroll down to CPU governor control section and switch your CPU governor to performance for example, you can also switch your scheduler to deadline in the I/O Control section
How to Automatically Switch your CPU governors for Games of choice (Paid)
- You need to purchase the SetCPU app or another app with similar profile functions
- Launch the app, leave the CPU governor at default ondemand, also leave the scheduler at default
- Go to the PROFILES tab and tick Enable profiles
- Press the plus sign at the top and then Turn this profile one when...
- Select App when asked to Add Condition, select apps again and then the game of your choice
- Press Next, make sure to untick set the CPU Speed, this because we still need to have the ability to use the power saver function so lets leave them at default
- Tick Set CPU governor and select Performance or any other governor of choice
- Tick Set the I/O scheduler and select Deadline or any other scheduler of choice
- Press Next Twice
and you are done! SetCPU will remain resident in the memory and switches to the your selected CPU governor and scheduler on the fly, when you exit the game it will return back to stock, keep in mind the app will remain running in the background so sometimes Android might close it but it will launch again, i suggest you don't close it yourself

Part III: More performance tricks
GPU Boost: Reducing Android's Native Resolution (Proof of concept for future performance needs)
The panel of the HTC One is 1080p and although the GPU is powerful there is no denying that almost 70% of it's performance is wasted in the jump from 720p to 1080p especially considering that even at 720p the density is still above 300ppi, thankfully many new games already offer in-game resolution slider like RipeTide GP2 or run in sub 1080p out of box like IronMan 3, RR3 and Asphalt 8, still if any game is badly optimized in the future you might want to use the following tricks in order to downscale the native resolution and almost double your GPU power, one more thing to keep in mind there are some games on the Playstore which fail to support 1080p like Need For Speed Most Wanted, forcing it to 720p will run this game with full effects including motion blur

CPU/GPU overclocking and underclocking comparative charts thanks to @jerrylzy
jerrylzy said:
@hamdir can we move this to #2 or #3 or whatever in the first page? so that users can see my results
I did some tests about overclocking and bottlenecks.
I know a lot of people like over clocking, but because of various bottlenecks, it is really not wise to over clock very high if improvements of benchmarks are excluded.
Overclocking tests:
Antutu:
ARM Miner:
Sunspider
3DMarks:
BaseMark X:
GFXBench:
GT Racing 2:
Real Racing 3:
Riptide GP 2
CPU Bound Tests:
From CPU Tests results, we saw magnificent increase in performance. The suggestion, however, is still not to over clock high.
at high frequencies, the cpu voltage might be so high that can burn up your cpu completely; also, high voltages+frequencies create extreme heat that are both uncomfortable for battery and human hands.
GPU Bound Tests:
We saw huge improvements in well-optimized benchmark apps, but real gaming tests do not show the same.
Overclocking to 501mhz above IMO is totally unnecessary, it creates little performance gain over 450mhz, let alone 490mhz.
It's amazing to see that my tests results reveal the same frequencies of sweet points as those @hamdir wrote in his scripts.
Bottlenecks:
I heard more than once people complaining about gaming performance on stock system/kernels. It is really not because of the performance of the chip, as @hamdir stated, it is because of thermal throttling that created a lot of bottlenecks to limit the graphics performance.
When the battery reached 40C, the cpu will be capped at 1134mhz and gpu at 320mhz; When CPU reached 56C, it will be capped at 1134mhz, and further at 1026mhz.
If your unit has difficulty in exhausting heat, the cpu might get hot quickly and your gaming performance is thus significantly reduced.
Bandwidth Bottlenecks:
When CPU freq is lower than 1026mhz, the L2 freq will also be capped at 648mhz and theoretical bandwidth will be reduced from 8.5G/s to 6.4G/s. a 30% drop in bandwidth surely resulted in about 30% drop in gaming performance.
So never cap your cpu freq below 1134mhz!!
CPU Bottlenecks:
CPU single thread performance also affect gaming performance. when GPU is running at 400mhz, CPU performance at quad core 1566mhz is very sufficient. If you enable powersaver, or your chip is throttled, your cpu freq will be capped at 1134mhz and resulted in significant performance decrease.

Been waiting for you to start one of these like you did on the HoX Looking forward to good news, and new games!
Wicked!
Another sweet Hamdir guide! :good::good::good:
The best part? with this tip, most games will run fine even with the Power saver function turned on! saving you both battery and thermals
Click to expand...
Click to collapse
This is amazing! So you can have Power saving on and still play games really well
I think I've now found my reason to root!
It's great that it'll do it on the fly too! Enter a game and it'll switch to the best performance, leave the game and it goes back to what it was before the game started, excellent!
yup this was my reason for root actually,
the moment i saw Beach buggy stuttering even in low resolution, almost the same between low and 1080p, I knew we will need to switch the governor
Msm dcvs does not play nice with some custom launchers like nova. The bloody thing stutters like it is 2 year old phone while scrolling through home screens on this governor. This governor too is not yet optimised for our s600 properly.
At the moment it is tradeoff either way. Or you have to manually change it each time before playing games. The only launcher that works ok with Msm dcvs is go launcher that to after some tweaking to animations.
From my HTC One, in your face.....

you dont have to set it manually, Setcpu profiles will automatically switch it for you and leaves ondemand for the launcher
there is no trade off with profiles
dont jump to conclusions so quickly, its essential for gaming, well worth the cost of SetCPU
I might just root the phone and install custom recovery, I don't think I'll bother installing ARHD... not for a bit anyway.

With profiles yeah it should but it still does not play nice with 2D games. Games like Hill climb racing does not play nice even with MSM-DCVS as well. Game stutters a bit. Only performance Governor seems to help a bit and even that can cause some micro stutter in 2D games. I play 2D arcade type games and most have similar problems with One. They fly on my Nexus and SGS4 and even Oppo Find 5 which uses Krait 200. HTC or Qualcomm needs some more work on this chip.
And I purchased SetCPU long way back to support the developers.

well it seems to differ between games, for example msm-dcvs does great for beach buggy, while i noticed MC4 runs very well using ondemand
this is the benefit for porfiles you can enable it for the games that benefits from it
added ondemand tweaks to OP
I'm gonna assume OnDemand locks 2 cores like the HoX, or is ondemand finally ondemand like it should be?

it wasn't the fault of ondemand, it was nvidia's fault where the maximum clock speed step is single core, so when the CPU boosted to max it actually locked into a single core crippling performance, non of this exist on qualcomm's side

what about battery life on msm governor?

natural to assume its going to be worse, this is why i never suggested to use it all the time and instead use profiles to call it for your selected games

right now im focused on reviewing stock kernel, later i might have a look at custom kernels
but after the strange death of my One X, im not too excited to mess with kernels
It seems some people here have not 100% understood (or fully read:banghead: ) Hamdirs post.
You can use setcpu to switch between governors per app. For example, as default it is standard. Press the icon for the game you want to play and the governor will change AUTOMATICALLY while playing. End the game and setcpu will switch back AUTOMATICALLY.
Thanks for the info Hamdir. Seems its time to root.

Cool. I wouldn't worry about that though since it's more of a freak case honestly. There are so many people using custom kernels for extended periods without any issues
ok i did some more tests
three things for sure
- also it's delayed, but throttling does eventually happens, i noticed when testing few games in a row performance suffered
- the 1.28 ondemand values in the OP are a lot better for gaming, so if you don't like to bother with profiles and SetCPU, simply changing back ondemand to the recommended values will do
- not all games are running well with MSM-DCVS, for example i suspect MC4 is running better with the tweaked ondemand (maybe MSM-DCVS is driving it to throttle too quick), NFSMW running the same on both, Beach buggy running much better with the tweaked ondemand but locked smooth with MSM-DCVS, another game running better with this governor is RR3
conclusion for now, tweak your ondemand back to the values in OP if you value your gaming the most at the slight loss of battery life, you can use profiles and MSM-DCVS for suffering games like Beach Buggy Blitz (i wish SetCPU profiles allows specific governor tweaks per profile)
i think any optimized games for the s600 (like MC4) will not require us to switch the governor (perphaps its switching on its own), this trick is only needed for games that so far do not specifically support our device or SOC
one more thing, it might be my imagination, my previous PVS2 was definitely running cooler and hence smoother than my current PVS3, maybe the GPU has it's own binning?
A Big Big Thank you hamdir !

Hello !
After long weeks of searching the answer and solution to my problem, I am exhausted. So I would like to ask the biggest Android community for help
Well, I know it's not new, but I have problem with my S7 Edge (Exynos) performance
I experience FPS drops in almost every game I play. As for games it's not that irritating, but recently I have bought Gear VR and while having this thing so close to your eyes, you see every frame skipping.
Apps for checking the CPU throttling shows that after 5-10 minutes the 4 bigger cores slow down to about 50% of their full speed. It leads to ~30% performance slow down.
I tried every solution that doesn't require root access and warranty void. For example: disabling certain packages and services (Game Launcher, Game optimization service); different settings in Game Tuner; performance mode; factory reset etc. Nothing works.
Does this kind of problems can be repaired on warranty? I know that in order to fix this you can change kernel setting, cpu governor etc but ofc they don't do that in Samsung Service Center. Is it possible for them to replace the main board and cpu with Snapdragon one?
I would not like to root my device because I didn't want to lose my 3 years warranty and I am using a lot of applications that may not work with a root.
Thank you in advance for all your replies
Did you try the game performance mode? As the "performance mode" is just screen resolution and brightness. The game mode is the real performance mode where the temps throttling is relaxed and higher clock speeds allowed(you can also edit the profile to set the resolution manually to wqhd). You can also try to set the resolution to full hd and see how it goes (tho for VR it won't be cool, but for the test it won't hurt). Also if the phone is new, it will need atleast 10 days to settle and become faster, smoother, better. Apply updates if they are pending too.
Otherwise you can't do much without root, but even then you are limited to what you can achieve so be careful + samsung have a fuse into the chip that burns out when you root the phone, it's not possible to hide the intervention and they can deny warranty for that reason (and often do so).

Thank you for your reply
Yes, I've tried "game mode" but there is no difference. Changing resolution to Full HD helps for a while, but the Gear VR software doesn't work properly on anything other than WQHD. It just doesn't scale properly and you are unable to see whole content.
I'm just wondering whether every S7 Edge has problems like mine. I understand throttling after 20-30 minutes of intensive gameplay, but ~40% slow down after 3-5 minutes seems strange, especially because phone doesn't even get warm.

Otherwise I don't have problems with gaming, the game mode smooths a little the already fluid gaming(but then again, the game I play mostly is vainglory and that game runs great on htc m8 that is almost 4 years old). You are talking about some more massive performance drop. Many phones start to throttle early and throttle hard, samsung is one of them for sure (they want the phone cold).
@hamdir can you lend a hand on that one? You are tons more experience with VR than me.

Well, there is an app called CPU Throttling Test on Google Play. I would be really thankful if you give me information how your phone behave in this app. Mine throttles hard after 3-8 minutes. Clock speed of the better cores goes down to about 1.6GHz each. Sometimes even below 1.5GHz.

From a cold phone, 1.9GHz almost right away(I guess the highest freq is only for burst load, like app launching) and kept for 8 minutes then drop to 1.57GHz on the big cores. So I think it's in line with your result.

Yeah, that would be it. Thank you for your time. So it seems to be normal, I hope I'll get used to it somehow
I also wrote an email to Oculus, maybe they heard sth about this issue and know a fix for frames skipping.
The notorious feature known as DVFS is the likely culprit. Some forum members suggest it throttles the GPU and CPU to improve benchmark results or otherwise to protect the device. I've noticed it can lock-up and end up overheating the device but that's just an anecdote.
You can try forcing the app to run at a lower resolution which Samsung's Game Tuner does for some games, or find other solutions for unrooted devices like capping CPU frequency for a smoother experience.

Almost all the phones are tweaked to use max freq only on single core load and app startup (burst). If their power management detect heavy load on all cores, it will automatically scale down to lower freq state to prevent heat building up fast. In reality in our case this is 1.87GHz for all big cores + the small ones (higher if only the big cluster is used, leaving the small cores off). The first actual thermal throttling level is 1.56-1.57GHz at around 8 minutes mark. Games would take a lot longer and in my observation as the phone is big and none will use 8 cores at the same time - there will be no throttling, just power management and stable fps. His case is different tho, VR is really a heavy one on the CPU.
As for DVFS (and extended to samsung power management, every manufacturer has it's own management) - it's there for a reason, to use your phone without major slowdowns due to heat and to be cold in touch, i.e. better for use. You can always change the behaviour via custom kernel, but you can't get more performance without heating the phone to the point of hardware throttling or uncomfortable to hold. Actually as you said - the right way if modify is to cap to lower freq and try to command the phone to keep them. This would still lead to a lot of heat, but will take some time to build up (and it will look smoother, tho with lower fps). OC is pointless for speed gains, will work only for burst loads. UV is not effective too as nowdays the SOC's are heavily binned for optimal settings from the factory.

I've been playing PUBG Mobile for a while now and wanted to ask you how you find the performance on our Samsung S8.
When I had Android Nougat it really sucked (a problem that shouldn't happen, because of the great potential of our phone). However, now that I have Android Oreo I can play normally and without problems, but I still find that I should run better because I have seen it installed in cell phones of lower capacity and have more fluidity.
Someone who plays it and knows some trick to get 100% potential out of our S8?.

I have an S8+ with the google wiz rom (It erased about 300 apps and has some optimizations) and I still feeling that my phone doesn't run the game as fluid as it should be
mine S8+ still has nugget. haven't received update yet. all the other apps and games run fine except PUBG, it freezes then restarts.
Mine s8 doesn't support hdr graphics and ultra frame rates in pubg
Hello
I have an s8 with custom pie ( hades rom ), max setting are hd and high fram rate, while rooting and removing all bloatware etc...
Just download gfx tools there is a paid and free version, i played it on smooth graphics 60 fps no lag at all, remember that internet speed plays a big role.
Hi, I know this is super late but what I've found about gaming on the s8 is that there is absolutely nothing that will affect the performance of the phone or your experience of the game more than thermal throttling. I tried for weeks to fix my lag problems with all kinds of kernel tweaks, network teaks, getting rid of background processes and trying to keep my ram free and was totally stumped until I realized just how much my cpu was being supressed by thermal throttling. Download GameBench to get an overlay of your in game frames per second (you should be able to get a constant 60 fps no problem until the throttling sets in) and get Simple System Monitor to monitor your thermal sensors and cpu frequencies. You should start to see an immediate correlation between your fps drops and your and clock speeds and temperatures. If your phone is rooted you can use Kernel Adiutor to set your cpu govoner to performance (it just locks your cpu at max clockspeed). This will make the throtting very easy to see in simple system monitor because you can see how your max clock speed is gradually stepped down as thermal engine overrides the govoner.
Now for the fix. If your S8 is a exynos you are a lucky b***ard and you can probably find a software solution for disabling thermal throttling like with a custom kernel or by editing a few system files. If your stuck with a locked bootloader like I am on the snapdragon s8 than the only solution is to actually keep your phone cool while gaming. I use ice packs wrapped in a paper towel. They only last about 30-40 mins so you may need several ice packs and keep them in rotation. Whatever cooling solution you use just make sure its not too extreme or too sudden as rapid changes in temperature are not great for electronics. That's why I use a paper towel as a bit of a buffer between the phone and the ice pack. Works great for me and I maintain 60 fps all game.
