CM10 vs SAMSUNG ICS roms - CPU usage

Not sure what to tell.. but many people know that Galaxy S II with CM10 (currently using 21. september nightly) uses around 35% in idle of CPU power.. just 5 apps installed.. same with HW composing disabled. and same with force 2D GPU rendering checked
While. samsung one rom does use in idle around 3-12% of CPU usage with force gpu 2D rendering checked
Games are smoother on samsung than on cyanogen (both are running siyah kernel 4.1.5 with oc at 1.6 + GPU 400 + touch boost to 400 (step4)
example games: GTA III, Gangstar Rio
Why?
Not sure what is bottleneck... if fsync (really don't messed with it)
or memory bandwith,I/O,GPU, or cpu
during Gangstar RIO..
cpu runs with both cores around 65% and game lags during driving..
GPU can't tell.. as MaliStats reports bad value (400MHz 1100mV 100,1% ) all the time
Any known fix for these lags and cpu usage?
Gangstar rio is less laggy when HW composing disabled..

Because the HWcomposer isn't working correctly in CM10 so you have lags in games.
CPU takes all the load in 3D games on CM10.
BTW this question should be in CM10 thread.

HW composer still doesn't work? it is much smoother than it was before 3 weeks
now animations are smooth while before.. they were laggy as hell

This don't mean nothing, simply they work to optimize in a better way their rom.

ERROR! You are testing both roms with a "custom kernel"(siyah).
Ask in Siyah thread.

HWComposer is not working fully, CPU is doing all the graphics works. You see smoothness due to other improvements and the Dual core CPU that's inside.
UC to 200Mhz and try scrolling, you'll see lags which you won't see if HWComposer is working correctly.

Hw composer is an issue, but sensor polling is another one, never resolved in cm builds, coming from cm7 days.
I tried contacting several developers, but none seemed to see or wanted to work on the problem.
While idling, sensors use +- 10% cpu on any CM based rom (at 200mhz), while on Samsung based the usage is +- 2% idling while screen is on, same conditions. Android system process is to blame, and inside the process sensors threads are the ones sucking cpu. Disabling sensors (autororate, light, gps) did not help to reduce the problem in my case. Using different kernels did not help either...
Had to live with the issue at this point...

Do You do similar comparison stock VS CM9?

Yes.. that sensor polling really uses a lot of power.. mainly compass one!
Thank's everyone.. usic Changmin vsync builds with dorinmax + 520MHz works good
with note HWC

S3 odd finding or placebo?

So, trying to improve my battery life I set my CPU to dual core, and for some strange reason, everything runs smoother now, from the interface to games.
Specially Contract Killers 2 and Dark Knight Rises. This games were a pain to play since I kept getting terrible stutter and lag and could only get good steady smooth performance overclocked which pretty much beats the whole quadcore CPU on the S3 if my gf stock S2 can run all this better than my S3.
I'm running Wanamlite Jellybean deodexed DLJ2 rooted with Siyah Kernel. At the moment not overclocked.
Only reason I can come up with is that most apps are optimized for dualcore CPU's since quadcore is not yet the standard.
Has anyone experience something similar to this or wants to try this out?
BTW, battery life hasn't improved much.
Samsung sure made a coding mess with Jelly Bean.

How did you set the device to dual-core ?

Stweaks when your running Siyah kernel.
Also you can remove lag from some games if you go to developer options and check "force GPU rendering"

I have been running Dual-Core mode as well for 2 weeks now, as far as I can see it's just as smooth as Quad Core mode. At least in the following:
-General UI (homescreen, scrolling trough settings)
-Whatsapp, Facebook, Other apps
-Simple games like Jetpack Joyride
I haven't tested heavy games though. Reptide GP is smooth, that's kind off a heavy game.
Battery wise I haven't noticed any big difference either between dual and quad core mode. But neither performance wise, which is weird since it makes the quad core processor seem useless.
Stock CPU & GPU frequency's, undervolted CPU -100mV and GPU -50mV.

Q : [i9500] lag when gaming on stock tw 4.4.2

Hi, anyone here have this lag issue too when playing game like asphalt 8 or gta : sa on stock tw 4.4.2 ?

Gameloft games are only optimised for Adreno and Mali, not PowerVR.
GTA SA lags with almost all android devices

Man, but this game no lag in stock tw 4.3 and cm11 even i used only 2 core clocked in 1.200ghz.. maybe this bug only in i9500 tw 4.4.2 ?

Probably Samsung's aggressive thermal throttling which was introduced with 4.4.2.
BTW, how on earth did you get games to only run on 2 of the 4 low power A7 cores?

I dont know, but game realy work without lag in dual core.. yeah samsung should work solve that bug i think.. i cant use 4.4.2 then..

i disable it in stweak using MaxFour kernel.. ain't a15 run too on 1.200ghz ? i think not only a7..
yeah asphalt 8 high graphic run fine on my i9100 and gta : sa lowest setting..

No, the A15s run at 1.6Ghz... which is what I am rather concerned about.
Because a normally functioning phone should utilise all cores and speeds should be fluctuating above 1.2Ghz in for graphically intensive games in your case.
The i9100 has a optimised Mali 400 GPU which should run GTA better than most Adreno or PowerVR of that gen.
It is also worth noting that the SGS2 is running at a awfully lot lower resolution at 800*480 compared to 1920*1080 which will require a lot more processing power than the S2 to run those games at similar settings.
Both GPU and CPU are important.

in setting a15 can run in 700mhz up to 1.600ghz, a7 100 - 1.200 but yeah i'm not a master on this thing.. you right resolution affect too in performance..

Have you tried forcing it to run at 1600Mhz in settings and perhaps lock your GPU clock as well?

Yeah bro i tried everything, cpu gpu min clock set to max freq.. tried gltools too still no luck.. this not happend in tw 4.3 and cm11.. so i guest this a something bug in tw 4.4.2..

[Q] Good ROM for heavy games

Hi, how's everyone?
When i bought my nexus 4 before like 7 months it was pretty good, and can handle heavy games like modern combat 4 and Asphalt 8 in high graphics, Now i cant even enjoy playing those games because of frames lags and stuff.
Could you please tell me what i should do? I tried to flash factory image still didn't solve thus problem.

A different ROM won't make any difference, unless it has its own kernel with some performance tweaks. Set CPU to On Demand, and GPU to Performance. Might make a difference. You could try a kernel with overclock, like AK, but you should make increases incrementally and keep an eye (or hand) on possible overheating.
If you were able to run things before, but now things are lagging with the same settings, It'll be because you've got extra crap running the background hogging resources.

I think Hells Core b57 can help u, dude. I tested this kernel w/ some heavy games and it did very well :3. But, play so many heavy games w/ that kernel can make ur battery drain very fast w/ b57 version include ur phone will be heat up @@

PARANOID ANDROID or CYANOGENMOD.
You can't go wrong with either of these ROMS
Plus you can download Franco's kernel for PA.
Under the CPU governer choose performance. This will cause all your cores to run at 1.5ghz regardless of the load on your system. Hence maximizing performance
There's a temperature throttling option in Franco kernel.
Google sets its GPU throttling at 37 Celcius. So when your phone heats up, the performance decreases.
You can actually override this default temperature so you'll get a better performance in the LONGER RUN.
Just don't crank it up too high. We don't want your phone to be extra hot.
But 37 degrees celcius is way too low when compared to other phone GPU throttling temperature.

Thanks everyone!
That really helped me.

[Q] What is the fastest rom for Note 4 Snapdragon. I have tried Lineage OS Pie

I have tried Lineage PIE (slow)- RR 7.0 which was fine - RR 8.01 which was kinda slow.
What is your setup and what is fastest/stable

I'm using LOS16 on my N910P. Phone seems snappy enough considering its age. The stock kernel uses a hotplug (mpd) so 2 cores are parked on occasion.
For sketching, performance doesn't call for concern. In this regard it's similar to my Note 8 actually. Switching apps and scrolling look to be okay.
CPU: 1.5/300 con, GPU: 389, IO: Noop
