Can you recommend me settings for S4 i9505

I'm mad cause i love to play FPS with Virtual Reality HMD Visor a sort of a really High end cardboard...

Unluckily there are no any serious game support cardboard just 3 minutues disgusting demo...
I'm praying for Gta cardboard support should be faboulus with the original android game to play...
The only choice i have right now is ppsspp wich support cardboard side by side mode and is still really nice to play but i find out is not 2x 3x 4x that change to much the gameplay the first minutes i start a session the game is pretty fluid let's say enjoyable but after 5-10 minutes don't know why start to lag like crazy and i don't understand why?
I hope this emulator would be better in the future
