FPS capped at 45???

I am using steam, I have selected the beta option, but my fps is still capped at 45. Does anybody know how to make my fps 60? Vsync in settings doesn't make a difference either. I have seen people play the game at 60fps and now this lower framerate is killing me :(

​

Edit: i literally downloaded an android emulator and am playing the game through an apk on that emulator since the mobile version isnt capped at 45, but if you have a fix for steam I'd love to hear it
