Low GPU usage on cyberpunk and possibly others

Hello! I’ve recently upgraded my system with 7800xt and I am having some issues while playing Cyberpunk2077 on lutris (bought it through gog). I am posting a short summary of outputs and info here: Output of Lutris’ “submit issue” -> 0x0.st/XAfJ.jsonOS: Arch System Summary: CPU:10700K GPU:7800XT RAM: 32GB ddr4 3200mhz monitor: Dell G3223D (144hz) mobo: z490 aorus elite ac

Drivers: amdgpu $ glxinfo|egrep “OpenGL vendor|OpenGL renderer”

OpenGL vendor string: AMD OpenGL renderer string: AMD Radeon RX 7800 XT (radeonsi, navi32, LLVM 17.0.6, DRM 3.57, 6.9.5-arch1-1)

This is a fresh Arch install, with all the drivers installed as described in the wiki page mesa, lib32-mesa, vulkan-radeon, lib32-vulkan-radeon

Output of lutris --version :

2024-06-23 14:29:10,771: The Battle.net source is unavailable because Google protobuf could not be loaded: No module named ‘google’ lutris-0.5.17

I’ve also disabled ReBar and enabled Above 4G Decoding in bios settings. (not much changed though)

ISSUE

Cyberpunk 2077 was installed through the “vanilla” gog launcher embedded in Lutris, using the first option (without autogen tags etc). I am running it with GE-Proton (latest) with DXVK and VKD3D enabled. I have Lutris Runtime disabled and prefer system libraries enabled.

Running the benchmark i get an average of ~61 fps with these settings (benchmark output). I’ve noticed that both my gpu and cpu never go above ~75% use I’ve also noticed almost the exact same (fps) results with other configurations, including having FSR on etc.

Strangely, during the loading screen or before the main menu etc, my gpu is at 100% and I have a solid 144fps. Also, in the starting area which are more “open world” I get a solid 100+ fps with 100% gpu (and high cpu) usage, on native resolution. While in denser areas (i.e. Night City) I am getting lower fps but with lower gpu and cpu usage too (same as the benchmark).

I am sorry if this is an off topic issue, but any help would be greatly appreciated.

EDIT: I’ve also tried switching to Xorg from Wayland and I m getting even lower fps on the benchmark (~about 48 average) with higher cpu usage and lower gpu usage. And generally, lowering other settings only lowers the

Maybe your ram is not XMP-ed or DOCM-ed or whatever, so it’s running lower then max advertised speeds?

jack_jack OP ,

Hey thanks for the reply! I have XMP enabled, at the profile running @ 3200mhz. I am also not sure about what you mean by DOCM

I think he means D.O.C.P XMP is a term for intel based CPUs ^^

Chee_Koala ,

Correct, thanks, I always forget the AMD equivalent name (even though I only ever build AMD rigs)

Ghoelian ,

don’t they call it expo or something on amd cpu’s?

Chee_Koala , (edited )

I think there are like 7 names and it depends on your mobo manufacturer with AMD XMP, even though normally CPUs have such easy to read naming schemes 🤣

I think you are getting a CPU bottleneck, try disabling some settings heavy on CPUs and check if it runs better.

Enabling Fsr increases the load of the CPU, and I think it is for this reason you don’t see any gains from it

jack_jack OP ,

Yeah that’s what I was afraid of. I find it strange though that neither gpu or cpu max out before I hit a bottleneck, but I guess not having 100% usage doesn’t mean you re not hitting a bottleneck (IOPS etc). Strangely though I’ve also used this mod (essentially a DLSS enabler) (separately from what I reported above) and I m getting a nice ~80fps+ again in heavily crowded areas. I have the expected drawbacks of frame gen though but it’s more playable. Maybe i’d also try it in a Windows machine just to verify even though I don’t have an installation at hand right now. Thank you!

Yes , the frame gen is there to help with those CPU bottleneck scenarios but as you stated there are some drawbacks. Maybe the cd project will implement the Fsr 3 natively (and reduce some of those drawbacks), but for now, sadly, that mod is the only way you can have it on cyberpunk.

If the CPU isn’t reporting 100% usage, is it running multicore? There’s a setting in Cyberpunk to switch between single and multi core modes. This may help.
