"Frame time" degrade after some time

VeilSilence commented 3 months ago

Greetings.

Nvidia rtx 3090.
Driver version 555.52.04. It also happened on 550 driver.
Kernel: Linux Nix 6.9.3-xanmod1
KDE 6.0.5 wayland session.
NixOS 24.11, but this problem was on Arch Linux also for me.
Gamescope commit 09cb7b451d8825e597d15ab9d30e43aee8418670

After some time playing, my game performance drops drastically.Here mangohud Baldur's gate 3 logs for example: https://flightlessmango.com/games/27057/logs/5383

I noticed that when it happens, GPU utilization also drops from 97% to around 60%. This occurs in any game for me. Game running from KDE itself don't have such issue.

Try adding LD_PRELOAD="" before the gamescope command.

LD_PRELOAD="" gamescope -w 2560 -h 1440 --mangoapp %command% I'll test again BG3.

Hmm 52 minutes and no performance regression. Maybe gamemoderun cause the issue. I'm gonna test with gamemoderun now

Thanks @VeilSilence, that makes this the same issue as #1292. Closing as a duplicate.
