AA setting is 4x for the newer titles.
I don't think the HDD is active during chops.
I don't think L4D and UT3 chopped on me when I ran them on my older PC at 25-30fps.
This seems to be consistent with the way Halo PC started chopping after I got a new system 2 years ago, again, it ran at 25fps on my old 2003 build.
I'm starting to think it's this LG 700P CRT monitor... I'll hook up a crappy 1024x768 LCD I have lying around here and see what happens.
Just tried it with and LCD (vga connector) and displays the same damn thing.
What the hell is this?
Let me explain this further, when I walk around and look at the ground, every few seconds it chops, like it's losing a few frames and fast forwards to them... something like that.
How the hell do I get the same damn thing on two totally different PCs is beyond me.
