Adreno 420 Drivers from Qualcomm site

Hi,
I currently use a custom TW based firmware for my 910F based upon POF2 firmware. I'm a software developer and developer an app that uses OpenGL ES 3.1. Now I have a problem which seems to be connected to the old version of the Qualcomm Adreno 420 drivers that came with the ROM. Every shader I want to compile fails with the error: "Built-In invariance mismatch". Those shaders worked on the same phone with all 4.4.x based ROMs before. So I now wondered if I can use Adreno 420 drivers for the Nexus 6 (Uses Adreno 420 as well) downloaded from the Qualcomm developer page (drivers from August 2015) and just flash the file to my phone? I already looked inside my system folder and the files on my phone are the same just much smaller and older versions. I'm a little scared if a break everything if i try this. So maybe someone with a little experience with Android drivers for GPUs can tell me if this will be possible?
Best Regards,

GPU Drivers

I guess most people don't care about which driver is included in ROMS as new ROMS are always coming out or being improved upon and with all of the details and specs being listed, driver versions are never mentioned. Is the v84 driver all that we can hope for, nothing newer? I've flashed countless ROMS an never saw anything newer.
Driver versions do matter, I wish they would be listed somewhere in the ROM description.

Somebody has to develop these drivers. You can't just go to a website a download them like nvidia drivers.
And as far as I know, Qualcomm only release the source code for the chips, leaving the development up to whoever is interested.

Is there not an updated driver newer than v84 that already works with the S4? The S4 has gotten official Lolipop OS upgrades, isn't there better drivers already made to work?
Surely Marshmellow OSs have better drivers. Are those drivers not able to be used on the S4? I understand someone has to do the work, but every other aspect of custom roms are being made to function, are GPU drivers just being overlooked as not being important enough to spend time on?

I don't know how this works. But if they could I think they would.
Obviously, Qualcomm has to update the drivers, as it's their chip. So maybe they dropped support for the Snapdragon 600 chips. I don't know.

drivers from another GPU wouldn't be any use to us.

Adreno 330 GPU Driver Update ?

I see that qualcomm has updated adreno drivers in a month, on their official web site: https://developer.qualcomm.com/software/adreno-gpu-sdk/tools
I'm wondering about how I'm going to do this. I've updated my old phone's adreno 205 driver before and there was a big performance increase. I believe this update will be nice to us. Flashing, odin or anyway ?

No official Nougat drivers?

according to Qualcomm (not sure how reliable the resource is)

Yes, this is somewhat old news now. Qualcomm dropped drivers for the Adreno 3xx series used on the 800/801, so we have no Vulkan support and thus cannot pass CTS. Therefore, we will have no official Nougat builds. I'm sure people are working on making the drivers from Marshmallow work (maybe not with Vulkan, but still at least be able to boot and have graphics work, etc.).

Oneplus One is in the official list of devices that will receive cm14, so i guess that driver support won't be a problem

"Official" list? Source? AFAIK CM hasn't posted anything since Nougat source dropped

As far As I know the latest exynos beta has the latest mali drivers included, I'm not sure about vulcan but the hardware is certainly compatible

There seems to be some improvement.

This video contains benchmark comparison between nougat and oreo and although everything is almost same in CPU department when looking at 3dmark score opengl 3.1 performance is similar but vulkan score have improved greatly 2192 vs 2529.
