I Have a problem with graphics and physics

Alright. I am using unity 5.3

Why is it that when my graphics settings are set below fantastic, my character’s jump (root motion) cant work and gravity seems way more intense in general? and why do I have to set gravity to 500 to get a result(in general,when graphics are set to fantastic)? And one more thing, when I set graphics below fantastic my mouse input is slower.

Just trying to fix this…

It might be that the graphics quality is affecting the framerate, and thus the rate of computations (gravity, etc.)

Try opening the profiler (Window > Profiler) to see the framerate.
