Steam Deck drop FPS after update. Please HELP
#1
Hello everyone! I play on Steam Deck.
I have been using PCSX2 via EmuDeck for about 2 years. Yesterday I decided to install a new game, went into EmuDeck and it updated PCSX2 to the latest version. Now I can't play, it's just a nightmare. FPS drops in games to 15-25 frames, and before it was a stable 50. I reset all the settings, made new settings several times according to dozens of video guides on YouTube. Deleted and reinstalled - useless. I don't know what to do, please help.

I played Prisoner of War PS2 and True Crime NY - now, unfortunately, it is impossible to play.

I used to set x3 upscale 1080p. Now I can't even play on PS2 render.

EmuDeck is just a hub. It doesn't affect emulators in any way. All files are loaded from the official source. Even when you click on the PCSX2 icon, it goes to the official site. So that's not the issue. I just updated to the latest version of PCSX2 and everything broke. Nothing helps, the weakest games that worked perfectly now can't even produce 30 frames stably.

Just tried Tony Hawk Underground 2. It's terrible, barely gives 45 fps... tried all the settings, I can't figure out what could have gone wrong. I just updated PCSX2 to the latest version...
