[Discuss] CM 9.1 Faster than CM 10.1 ?

[r12500]

I've been using cm 10.1 for more than a month now ... and i have tried almost every cm 10.1 rom and they were the same when it comes to lagg or speed...
but when i tried cm 9.1.0 again i noticed the BIG difference between this two roms !

clearly CM 9.1 is way faster than CM 10.1 though it should be the opposite..?

but the battery is better with 10.1

so anyone know why is that ?

The answer: drivers.
Even tho we have awesome devs, having the official kernel from HTC for ICS and not yet JB makes mostly that big difference on performance.
That's the only thing I can think of that has most impact.

Project Butter needs some power too, so that might be another reason.
