How to setup game looping for testing?

[Master [H]]

Basically, I want to setup a game to loop to hammer my video card as I'm trying to overclock it. I'm not having any luck with benchmark tools for specific games. I don't really feel like purchasing 3D Mark 03/05/06 just for the looping features, but how would I go about making some sort of script to loop a sequence until I stopped it.

I'd like to use Doom3/Quake 4/Prey or FEAR because those are the most graphically demanding games I have in my possession.

Thanks.

You'll find plenty on this page at Guru3d.

I've used the Far Cry and Prey bencmarkers and they work very well.
