Bug ID: 48901 Summary: Agents of Mayhem has terrible performance after a few seconds Product: Wine Version: 5.5 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: qsniyg@mail.com Distribution: ---
After loading Agents of Mayhem, the menu will start at ~60fps, but then after a few seconds, it reverts to ~2fps (with a frametime of ~300-400ms). The issue happens with both DXVK and WineD3D.
The CPU usage isn't particularly high, and the audio plays fine without any glitches (pops would usually happen for extremely low framerates when cpu or gpu limited), which led me to believe it might have something to do with the sleep time. Changing the graphical preset makes no difference, but uncapping the frame limit (from 60fps to Uncapped), it immediately doubles the frametime (~300-400 to ~600-700ms), and reverting it back to capped immediately reverts the frametime back to ~300-400ms.
Disabling esync/fsync makes no difference.
