Yes, really.
But you should totally check out that regedit thing. I just went in there and started messing around with the values.
I just finished playing Crysis on full stats on my Pentium II 450, with an ATI Radeon 7200, 32Mb of video memory. And I think I have 64 MB of ram. Oh, and I'm running Windows 3.1. Also, my monitor is made of diamonds. And if you are still reading this, then you obviously know nothing of computers
DO NOT EVER piss around in regedit unless you know exactly what you are doing...I'm gonna go play some more Crysis
