Right not too sure what forum this should go in because it could be due to a number of things.
First a little backstory. Once upon a time I, using rig in sig, started playing about with Fraps recording MW2. I would first make some videos using half size 60fps, recording was smooth, and almost always at 60fps. Some time passes and I try recording again, this time at full size so I can make 720p videos. The game then jitters from 40-60fps constantly and ruins everything.
I then tried taking it back down to half-size. However the jittering persisted. I am starting to wonder if my hard disk cannot keep up with playing the game and recording huge uncompressed AVI files both at once as it used to. I've had the disk for about a year now, I defrag it pretty often, is there anything I can do to it that could increase its performance? Or is it time to buy a new one?
BTW I was also able to play these videos back smoothly in WMP, VLC, VirtualDub etc. Now they jitter even more than when I'm recording them.
