Core i7-860 MSI HD5770 4 GB RAM 2 Raptor 10K HDs in RAID 0 for video capture. All settings at max. I think the graininess is due to the RU-vid re-encoding of 1080p video. For my future submissions (Check Sacred 2) I uploaded 1072p videos that look much better when played back on youtube. Its just a quirk of how RU-vid does 1080p re-encoding.
