I'm running with a Gigabyte GTX 970 G1 Gaming on a i7-4770K@4.1GHz
Using an HTC Vive via Steam VR
I'm running with the following settings ...
I'm not able to super sample at all and occasionally I'll drop frames for a few seconds in a space station but most of the time it's solid at 90FPS
The graphics leave a lot to be desired at these settings. I'll hopefully be upgrading to a GTX 1070 in a few months.
