It seems like I'm having issues after the recent OTA android 11/one UI 3.0 update with gaming, particularly Asphalt 9. After only 15-20 minutes of gameplay the game gets really choppy, the sound stutters and within 5 minutes becomes unplayable. I can't work out the issue, the phone doesn't get hot so it's not thermal throttling so I'm wondering if it's poor memory management? Is there a new setting in the update that I've not spotted that is restricted memory usage? I play all my games through the pre installed gaming app using optimised settings.
Any help would be great as this issue was not there on Android 10, I could play for hours with not even a dropped frame.
