Max hz/fps should be limited to your screen's maximum, which is typically 60hz on LCD's.
my max events are set at 70 and i get as good benchmark scores as anyone (690-700) for 3d antutu score. Im using ta kernel so v-sync is on, so some may see people with 720-730 floating around, this is NOT because of max events.
All i did in build.prop regarding this tweak is
debug.sf.hw=1
debug.composition.type=gpu
windowsmgr.max_events_per_sec=70
debug.performance.tuning=1
video.accelerate.hw=1
Obviously delete dalvick and cache for good measure
Thats all you need as far as i can tell. The first post needs to be updated
