Describe the Bug

I noticed a significant drop in performance on latest release on SteamDeck. Game used to run at 25-30 fps with little stutters on dceb79e and now with the latest release the game runs at sub 20fps and stutters a lot, fps can get to 10fps. I am using dceb79e again since performance back to normal with that version.

Reproduction Steps

Open game, run around central Yharnam. Game used to run around 30fps on dceb79e but now with latest release it can get to 10fps, stutters a lot.

Hello, looks like issue is also present on the Main pre release [ddc658f], Main [squidwars] runs almost as good as your version dceb79e (but your version is more stable, better fps), the main pre release has the same problem as your current release. Should I add the issue to the main instead of yours?

Yes thanks i will follow u issue on main shad to push a fix when it available

[DiGik05]

I will close the issue, someone mentioned the shadps4-emu#1973 PR could be causing the issue on some linux systems.

[DiGik05]

Closing issue, opened new issue on main shadps4-emu#2048
