I really wanna test out my GPU and play around with the graphics, but i dont know the drawfps command.

r_displayinfo. But it doesn't work?

Anyway, you can use Fraps to draw FPS.
There are some similar software.

Well thank you, sir! But if it doesn't work i'll just use Fraps, since i have it installed.

And why do you ask that if you could use installed fraps, without that thread, to calculate your fps?
