Is there a guide to gain and much FPS as possible!

Hey guys, i was wondering is there a guide to get as much FPS as possible such as commands like:
Grass.on false
are there more commands like this to increase the FPS and obviously the awesome level down ect ect.

Thanks Steve

Not that I know of. Also, the grass.on false command only gives like 2 fps… lol

Also if you press F1 and then type grass.on false it helps A LOT
