Title: Testing the VRAM valve patch

Hi guys and gals.. I've been testing the valve VRAM patch and got funky results. I know that its intended for setups with less than 8gb, but the results are interesting nevertheless.
Setup:
Ryzen 5700X. 24GB DDR4 RAM, Radeon 6700XT 12GB.
I've tested with the VRAM patch and without it same kernel (7.0)

Cyberpunk with the patch

Cyberpunk without the patch

3D Mark firestrike

without the patch

And this is really funky... I got far worse results with Shadow of the tomb raider with the patch applied

without the patch

other games I tested were Batman AK, and RDR2 but both had no difference, fps were the same.

Should I delete the post and do it again? because I cannot edit the post anymore, its somehow marked as read only. Or maybe the editing went into the moderation queue, for approval? I replaced the links with catbox.

is the only difference the VRAM patch or are you upgrading the whole kernel?

I compiled the kernel with the patch and then compared to the results form the standard mainline kernel from ubuntu, same kernel 7.0... but also you need two userspace utilities.
