GSC GameWorld released S.T.A.L.K.E.R.: Clear Sky Benchmark. You can see how your rig is powerful and compare with other rigs. Benchmark doesn't requires the full game too. I like this tool you can download from here.

Nice.
Will post results soon.

Well this was handy, now I KNOW I can't play stalker on my laptop, at least not without it looking like a cheap quake 3 engine game and that's too much of a sacrifice...

playing ut3 and bioshock on my laptop is funny.

I've already been playing STALKER: Clear Sky on my main gaming rig, but I might do the benchmark for the hell of it anyway.
