Ok, here it is:
I run Windows 10 on a different SDD, same computer:
I5-6600 @3.30 ghz
16gb DDR4
GTX 970 Strix
Corsair MK2
MSI z170 A PCMate
I tried to install the Oculus on that SDD, had to perform a firmware update for the Oculus.
And VorpX does a GREAT job. Skyrim, maxed out settings, no jitter, no lag, just a sweet ride.
I prefer run VorpX on my main setup with W7.
Any idea what driver/problem it could be that prevents Vorpx from performing as well on W7 as it does on Windows 10?
