I have recently wanted to play some .io games as they were recommended to me. When i try and play deeeep.io i get max 55 fps and average 45. This does not make sense as when playing other more intensive games like Rise of the Tomb Raider or Terra Tech my PC runs them fine at 60 fps.
Specs:
CPU:i7-7700HQ
GPU:960M
RAM:8G
Temp while doing this is low at around 45°C on both the CPU and GPU.

I am a rather new user to Ubuntu so i have no idea why. Everything is set to performance in NvidiaXserver and the process is set to -20Niceness. Any suggestions as to what is going on are greatly appreciated.

-Thanks
