Nothing Phone 2
After the 3.4 update, the in-game graphics settings were updated to 90 FPS.
You must select Smooth and Extreme +, which only gives you 60FPS in-game. To fix this, minimize the BGMI app to the pop-up view and then return it to full screen after starting the match.
In my gameplay, the fps fluctuate from 60 to 90, but it’s better than 60 FPS.
