Low performance in DOOM Eternal

Thank you, it’s fixed!!!

Nvidia drivers 440.66.07 (beta) seems to have boosted performance in Wreckfest by maybe double. It’s still half of what I get in Windows (80-100fps vs 33-50 in linux) with:

  • 24 cars on screen
  • Ultra settings
  • Fairfield demolition

I also have an issue where if I don’t have g-sync enabled, then the steam overlay FPS counter seems to show a cap of half my max refresh rate (50 for 100hz screen), and it never seems to dip below 33fps. G-sync enabled appears to allow higher fps, and also never dips below 33fps. Because of this I’m quite uncertain of the actual impact or fps accuracy, but the game is feeling very smooth.

TL;DR: It seems the D:E fix also had a big impact on Wreckfest

Just got the driver installed and it’s running great. Now I can’t blame the frames for sucking. Sad!

I can confirm, this seems to have done the trick. I built my own RPMs for Fedora, if anyone else needs them please let me know.

Thanks nVidia for caring about us!

Thank you for the quick fix!

Yeah they’re pretty responsive when something like this goes wrong. I found this forum is usually the quickest way to get something fixed.

While the 440.66.07 driver fixed the low performance issue (thanks for that, BTW), after some time playing the game I’m starting to see graphical glitches, such as flashing green lights and occasional geometry distortion. I’m pretty sure it’s not a hardware failure as the game runs without these issues on Windows on my system.

Maybe a video memory problem again but the other way around? What does nvidia-smi -q report about vmem usage in that case?

Because I mentioned in another reply above that Wreckfest performance was improved a lot with 440.66.07, I just tried the more recent driver version 440.66.08 and this seems have have boosted performance in Wreckfest yet more still, to nearly half of Windows (where it was 1/4 first, then 1/3 with last driver).

It doesn’t look like memory usage is the problem. nvidia-smi -q says:

    FB Memory Usage
    Total                       : 11016 MiB
    Used                        : 9403 MiB
    Free                        : 1613 MiB
    ...

        Name                    : DOOMEternalx64vk.exe
        Used GPU Memory         : 8000 MiB

Although the round value of 8000 MiB VRAM usage is peculiar. System memory is also fine: 6.1 of 16 GiB is used.

This is on RTX 2080 Ti without overclocking.

Hello,

I’ve encountered an interesting performance issue with the current 440.82 driver. For some weird reason it’s lower than it would be on Windows with the same game settings when running via Proton but… if the Steam overlay is active while in game, the GPU and RS meters turn from red to green.

I thought that it may be just a powermizer setting but it’s not. Something else happens when the overlay is active that causes rendering to actually be faster.

Linux:

Windows:

Sorry for the quality, I had to take these with my phone:

With Steam Overlay:

No overlay:

Update:

I recalled that I actually can have the Steam overlay active at all times. Just turn on the fps counter (Settings -> In-Game -> In-game FPS counter

I turned it on, left it in the bottom-right corner. It’s small and gray and doesn’t bother me at all. Result:

GPU and RS are back in the green, CPU in red just like on Windows.

Weird part is that when the overlay is not enabled, the bar showing CPU activity barely shows anything. So is the CPU not being asked to work hard which causes the GPU to “idle” or is it the other way around?
