I tried out the new Nvidia drivers for Linux tonight, and thank you very much! My swap buffer time is *much* less. Excuse the single eye menu / stats bug:
Installed run from:
Added this to my /etc/profile of course:
# thendrix - Add for oculus rift sync.
* 5ms typical frame in 2d
* 13ms typical frame on DK2
* Ignore the spikes which included some shader uploads over HTTP, screen caps, and such. ;)
Edit: TwinView and 3x displays could sometimes make typical frame 27ms previous to this change if you didn't know. These new numbers are with Twinview enabled and not using a separate X display. Previous to this it was recommended to disable Twinview or run game in a different X display due to sync issues between 60Hz IPS displays vs 75Hz DK2. I'm using a GTX 760 on a i7 with 6 HT cores, and my game engine uses a lot of threads. Looking forward to getting a 970 for CV1 if it has Linux support. :D
