Hello all! I am reaching out to you because I am at the end of my wits wit this.
Recently I have performed a clean installation of Fedora and installed Steam through Flatpak. That turned out to be a mistake however, as literally nothing worked out of the box.
After hours of debugging, I managed to get some games to run, but Cyberpunk is still giving me troubles. The game itself starts, and the performance initially turns out to be very good. I am seeing 80 FPS to 120FPS depending on settings. After a short amount of time, however, the GPU utilisation drops to 50%, and I get 10 FPS to 20 FPS max regardless of settings. Interestingly, the performance goes back to normal after another short timespan. These two states repeat I think at least almost periodically.
The problem is that I cannot see any trigger for this. CPU usage is not unusually high. Temps are fine. RAM is fine. VRAM is fine. When the problem happens, the power draw of the GPU decreases significantly as well and the CPU usage spikes slightly,
Previously, I was on EndevourOS with the non-flatpak client and everything worked more or less fine.
Also, Cyberpunk 2077 is the only game where this happens.
System Specs:
Type: Laptop
OS: Fedora KDE 42
CPU: i7-13650HX
GPU: NVIDIA GeForce RTX 4060
GPU Driver: 570.133.07 - RPMFusion (Same version for flatpak)
RAM: 8GBx2
SSD: NVMe
Steam launch options: NV_PRIME_RENDER_OFFLOAD=1 GLX_VENDOR_LIBRARY_NAME=nvidia WINEDLLOVERRIDES=“winmm,version=n,b” %command% --launcher-skip --intro-skip -skipStartScreen
I would be thankful for any suggestions! If you need any more info, let me know.
UPDATE 21.04.2025:
I think I have a lead to what the problem is now. I believe the issue is that the CPU is throttling and then bottlenecking the GPU. The actual problem is however that it throttles when running at 85°C which is way to low for this.
Right, accurate version is a good point. I will reply here and update the post as well
Driver host: 570.133.07 Driver Flatpak: 570-133-07 Fedora: 42
So the same basically. No protondb tweakes helped for me.
As a diagnostic, have you tried running it on reduced settings and see if it still does the same thing?
I can’t imagine it’s the Steam client, but might be worth just installed the regularly distributed version and see if there’s anything different there.
Just tried the native client, same problem. I also noticed the whole DE lags, so maybe it’s a KDE problem?
Likely not. I’d start digging in logs. Maybe think about a full reinstall of the Nvidia drivers. Disable VRR and any compositing effects while testing…etc.
I have already tried setting everything to low but no improvement.
I guess I will have to try the non containerised client.
Do you have any system meetings from while the game is running? Maybe give MangoHUD a try.
What’s your swap situation?
