Android Fake API Level

Hi Guys

I want to speed up games at my phone,
I have an Oneplus One 64GB and on Windows Bluestacks
I have found GLTools 2.0, it give some more speed, but BlueStacks is more faster with loading,
THen a compared the screens and saw that my phone has lots of more objects/effects at screen, BlueStacks has most of them.
Bluestacks has API 19 with 4.4.2
OnePLus One has API 22 with 5.1.1
Now i search a tool that can help me to speedUp games, like a FAKE API , FAKE CPU, FAKE GPU
maybe you can help me here?

here are 2 screens, 1x Phone, 1x BlueStacks
