Pop suggested to use the fraps demo to show the stuttering/clipping? problem I've been having lately (since about Christmas). It's got no audio, but the audio isn't a problem. Zombies flicker and 'skip around', sometimes there are clipping problems (like when Mutfox looks like he's in the floor, and I've had floating hunters; they pounce someone and the person is on the ground, but the hunter is in the air over them and above my head). Hunters themselves show the problem pretty well.
I had to encode it in Xvid, Divx once again gives me some 'error code -2' and won't let me use it to compress. The only time I've gotten the Divx one to work since Christmas was yesterday for a
Persona 4 video, where it had stuttering also (which it never had before). The stuttering does not appear to happen in single player, only campaign or vs online modes. And the net graph ping has been way off since Christmas too, it tends to say about 300-400, yet when I hit ping, it's half that. During the NM2 crescendo, it jumps up to 700, and I check when it is 500, and I have 100-something ping. Mutfox wonders if a video codec got messed up? I don't know.
I uninstalled the game and reinstalled yesterday, but Mutfox says that Steam Cloud thing (which I've now turned off) kept my settings. I deleted my config before uninstalling yesterday, and that didn't do anything, neither did turning off V Sync. Any ideas or suggestions on how to fix this really annoying problem?
