This is just preliminary observation, but it appears somehow Bandicam is causing frameskips and stutter on older Unreal Engine games, such as Unreal 2, Advent Rising etc.
The moment I start recording, the game starts to jitter. Even inside the game your controls are skipping beats. When you playback the video capture, the video may even contain bigger portions of frames skipped than when you were playing. FPS counter display still shows high framerates - anywhere from 60fps to 120fps. Limiting FPS during recording (to 30fps for example) does nothing to alleviate this issue.
Choice of codec had no impact on the skipping, from lossless (Lagarith, UTVideo) to H264 (x264vfw), every codec causes a skip. The only difference is that codecs that compresses more, skips more in the recorded video. The in-game experience is all the same - some skipping, some jumping... you either oversteer/understeer or you aim too much to the left or right.
Curiously, a competing video capture software, MSI Afterburner, exhibits the same behaviour as well, but FRAPS does not.
However, on modern Unreal engine games, Bandicam does not cause this behaviour. FPS may drop a little but the recording is smooth enough and the gaming experience is normal.
Question is - has anyone have a workaround for older Unreal Engine games? Or do I really have to fall back to using FRAPS? I really don't like FRAPS much eversince discovering Bandicam
