It seems that my game has a frame rate cap of 63 (measured with Fraps). I've forced Vsync from Nvidia control panel and in-game Vsync has been turned of by editing game files. I was trying to lock the game to 60. I have a 144Hz monitor.

I want to know if frame rate above 60 will break physics or speed up the game.

If I attempt a frame rate over 60 I get frame tearing when panning. Nothing in the game speeds up no matter what FR you run. An ocassional 63 for a second or two is normal.

I run my monitor at 120 but in the invidia setting I use the V Sync adaptive (half refresh rate) and I have the vsync checked in the games settings.
