I understand some of the people who realised that games which support higher refresh, but OnePlus was capped to 60fps for massive games, this is ridiculous. Before I provide solutions to unlock 90fps, let me share some thoughts about how I discovered that games were capped to 60fps!
https://play.google.com/store/apps/details?id=com.razer.cortex&hl=en just provided new features to able shows FPS, but I discovered that while I playing Dead Trigger 2 with max settings, the phone shows 60fps. PUBG China version able to running with 90fps without stress!
Image below is Dead Trigger 2 which capped 60fps by OnePlus:
Below is PUBG China version:
So I suspected that OnePlus done something for it.
So I tried jOnePlus Tools [adb/root], and Force 90Hz:
And... volia! Full video link showing many games finally runs 90fps: https://www.youtube.com/watch?v=nIT0yBCPwis
If anyone doesn't trust the video above, you may try the app that I found to Force 90hz for your OnePlus device, witness it for yourself. I understand force 90hz on gaming will cause battery drain, but we have Warp Charge which still retains fast charging speed while gaming, so who cares?
I hope the OnePlus team developer can do something about frame limited issues on massive games.
