Bloatware remove zenfone 5

I'm using the zenfone 5 1.6ghz 2gb ram to play games (Mu origin), I already make root in it, and I want to know if I can remove any factory app, and if there is some app that improve zenfone 5 in games.

I already installed Seeder and No Frill Cpu, but look like there is no improvement.

Thanks.
