Performance issues with Doom Eternal (small VRAM size)
The performance of Doom Eternal when I use RADV ACO, or LLVM is so much worse than AMDVLK, and amdgpu-pro-vulkan. It gives me half the performance of the latter.
Also, I get strange graphical glitches when using
RADV/ACO like what you can see in these 2 pictures:
I tried using
RADV_DEBUG=zerovram to fix the graphical issues, but it makes no difference.
AMDVLK, and amdgpu-pro-vulkan gives me good performance, but they crash a lot, so RADV is my last hope for running this game.
