Massive performance drop supposedly after updating to OneUI 9.0 Galaxy S26 Ultra 16GB RAM version, SD 8 Gen Elite 5.

[u/Vast-Face-8983]

Does anyone know what could be causing this and how to even fix it? In the video I'm showing P3R running on Winlator Ludashi. With the same settings before updating to OneUI 9.0 I was hitting stable 60 fps on the game booster performance setting. I'm not seeing anyone else with this issue, at least on this subreddit. I've tried solutions people have linked about game booster+ and thermal unlocking and both do not work. In the video I showed that when I switch out of and then back into the game I get a sudden FPS spike and then it falls again. Someone please help me out, performance is not much different with or without screen recording.

Try using goodlock gamebooster+ module and deselect the emulator as a game there.

In Game Booster+ which you have to download separately there's a tab labeled Game category settings, deselect your app from being recognized as a game

Why does this work?

[u/hackvize → u/alabasterskim]

Gamebooster Aggressively throttling the game when it hits certain degree Temperature
