I just got my G501 with 16 Gb ram and 960M GPU and I've spent 2 days going through and testing different video players including VLC, Wonderland and PowerDVD 15. So far PowerDVD works the best but i'm still noticing some jittering and would like to ask ASUS to give an OFFICIAL recommendation for which player and settings to use to fully utilize the 960M for smooth 4k video playback. If anyone else can sound off on this as well I'd appreciate it.. Thanks!
