Android 10 + miui 11 performance problems

[MinhocaMan]

Hi everyone! I buy a k20 pro with the secret rom witch dont receive updates, this rom has pie+miui 10 and everything works fine, then I instal xiaomi.eu rom with twrp with Android 10 + miui 11 and I got performance problems in games, massive lag and freeze too, before that I flashed the mi9t pro global stable rom pie+miui 10 and again everything works fine, two weeks before I receive the ota update to Android 10+miui 11, install and had the same performance problems... I made a research and cant find anyone talking about It.
Please guys, there are someone who get this problem? Anyone knows how to solve? I made some mistake? Thank you!

Untutu give me 425224.

Looks like happen only on certain situations like gaming, I dont know what to do, SD 855 should run every game easy like was on pie + miui 10. Maybe Android 10 issue? Idk cause no one talk about that.

For anyone experiencing performance and battery life issues after Android 10 Miui 11 update, I think I found a fix! All you need to do is to disable Miui optimisation, you can re enable it afterwards (better to do a reboot too). All it does is reset all the permission settings and some other stuff, Android 10 is known for its permission management which led me to believe there was a compatibility issue with the system settings and the permission management. My home screen was laggy and I had huge stuttering when watching a video and doing anything else at the same time, also I was unable to watch 4k60fps videos without lag, like I was able before update, now everything is back to normal
