Since I got the Galaxy S3, I've been running KitKat. More recently, I've been noticing a significant drop in 2D performance. Ive wiped and flashed many different KitKat roms with different kernels, and they all perform poorly, in benchmarks and UI, with 2D performance. At one point I managed to "fix" the drop in 2D performance in benchmarks, but it resulted in a HUGE drop in CPU performance.
Has anyone else experienced this problem?
