im experiencing the same vram behavior and performance issue that was described in this post [image] Low performance in DOOM Eternal Linux Hello, I’ve encountered an interesting performance issue with the current 440.82 driver. For some weird reason it’s lower than it wou…

This issue is fixed in the newly launched 470.42.01 Beta.

Maybe some round-up of the known infos of this bug: AFAIK, Doom Eternal uses (slow) system memory instead of vmem when run on nvidia. So Nvidia did this: 2020-04-07 version 440.82 * Added a workaround for Steam Play title DOOM Eternal, which overrides application requested memory locati…

That is native Vulkan. So maybe the workaround was v440 exclusive? Not possible. That workaround will always be needed unless app side fixes it’s behaviour.

Yes, feared so. Though rather puzzles me why this is only happening with the Linux driver and not on Windows, if Doom’s using Vulkan natively.

i almost finished downloading doom 2016 but i decided to look at what Vulkanguy pointed out and doom eternal report 4342MB of vram so there is a problem there

i have the same bug on doom 2016 exept that it runs at 1-20fps BUT it use way more vram still report the wrong number and is unplayable

Clearly there is something wrong with GTX 1050 4 GB Mobile but since @amrits tries to repro with a GTX 1650 he is not able to repro.

i found something interesting in doom 2016 if i switch to nvidia only (disable offload) i get adequate frame rate, but the vram still display wrong so i don’t think this isn’t the issue. but doom eternal is still unplayable i tried to uninstall lib32-vulkan-intel and vulkan-intel from my system bu…

i just noticed that dmesg report nvidiafb: unknown NV_ARCH

nvidiafb should be blacklisted when the nvidia driver is installed.

thanks i no longer have the error but no luck for the game tho
