I've just got my Rift working in DCS, and I have to say I'm blown away by it, even with the settings on low and not been able to read anything.
One thing that I'm sure has been brought up already is the size of the cockpit, it's almost like a mini version, my knees are where the pedals would be if it was real, everything looks tiny.
It's very promising though, I have a Playseat and the TM HOTAS, but there's not much need for anything else. It's gonna put cockpit builders out of business!
I'm using an ageing GeForce GTX 670, what would you guys replace it with?
