Enabling adaptive sync causes huge frame drops
I recently switched from an Nvidia GPU to an AMD GPU (and
bazzite-nvidia-open:stable to bazzite:stable), and this has caused several games to start behaving strangely with adaptive sync (FreeSync Compatible) enabled.
Sometimes randomly, but more consistently after alt-tabbing out of and back into a game running on Proton, the framerate will dramatically drop (sub-30 FPS). This sometimes lasts for a few seconds, but other times requires more alt-tabs or a game restart to fix.
MangoHud does not show any dropped frames, but my monitor's FPS counter shows it is dropping to 16 FPS. This behavior does not occur on any native Linux games that I have tested or with adaptive sync turned off.
Is this a consequence of rebasing fromnvidia? Is it an issue with the AMD drivers? Proton? My monitor? Are there any known solutions, or will I need to leave adaptive sync off?
---------------------
I have tried the following to fix the issue:
* Renaming ~/.cache to regenerate it
* Trying both the Automatic and Always (on) options for adaptive sync
* Trying both borderless and exclusive fullscreen modes in games
* Adjusting "Vsync" settings in games (Vsync on seems to reduce the occurences)4 replies
