IDK how they did it but, on my setup:
Win10 64 bit
i5-4670k
8gb Ram
2x nVidia GTX 770 (SLI disabled)
EDH is AMAZING! Even Ultra settings is playable, smoother than medium used to be. VR High and VR low is butter smooth. I mean BUTTER smooth. I have NOT been down to planets yet but, if flying around a station, one of the biggest in the game I've seen, inside and out, is any indication, holy $#!%&^.
If you have a system at or above my specs you have no worries, you can definitely play EDH, with no problems.
Seriously, I don't know what to say. I'm blown away. Forget the CV-1 (I will get one some day) my DK2 is even better now than before and I loved it before.
Congrats FD, you have the best damn VR game out there. I tip my hat to FD and take back 13 bad things I may or may not have said in the past. You guys nailed it. [up]
