You already answered, Esel - it has a lot more options. And it runs better. I tried many recording software when we needed to make vids of our DX9-based real-time 3D apps quickly (without frame-by-frame rendering) and gamecam showed best performance and best vid quality. Later on I compared it to fraps when recording some BF2 shit and I liked gamecam vids more. Still it's a question of personal prteference.
