Software used: Shadowplay, HitFilm and Handbrake
Source recording: 1280x960, 60fps, 20 MB/s (100 mbps)
Rendering time in HF: 13 minutes (720p60fps, H.264, 2.01 GB)
Compression time in Handbrake: approximately 10 minutes (720p60fps, H.265, 137 MB) I'm definitely happy with the way it performs. Firstly, my laptop couldn't even record at more than 30fps, and especially not on a high resolution like 1280x960. (it's a 4:3, I forgot to change to something else before recording)
I'll hopefully finish with the benchmarks. I have to test BF1942, BF2, HL2 etc.
So far, 3DS Max has been tested, and Crysis.
