With that out of the way, it seems like every AOSP-based rom i try (whether it's cm10.1, cm10.2, cm11 (3.0/3.4 kernel), miui, carbon etc etc just to name a few), gaming performance is way below Sense based roms. Is this because the Sense drivers are better optimized for Sensation? Is it a GPU tweak I've missed?
For example, on Sense roms I can play Temple Run 2 on Best Graphics and Asphalt 8: Airborne on Medium without any form of stuttering. On AOSP-based roms however, this turns into a slideshow. Have I missed something here? I'm desperate for some decent AOSP-GPU performance.
