I tried recording the other day using fraps and it was fucking terrible. My C-rpg runs on my solid state hard drive (c: drive) and my recording was going to my E: drive. I have a basically brand new computer, and even trying to play at 60fps (which locked my in game to 60fps) was fucking retarded, I couldn't play for shit. I normally play with 200+ fps in game, so that may be it, but I used to play games back in the day with 60fps and it wasn't hard to play at all. With Fraps it was laggy as shit on 30 or 60 fps. If you try to customize it, the highest it lets you go is still 60fps.
So tonight I'm going to experiment with another program I found online...but it's possible that I just need to retry Fraps using half video size or something? I play in 1280x1024 on pretty high settings normally.
