Quick update…. I had the IPD value (in VorpX set to 68 … which is my IPD… but VorpX IPD is no way accurate and I have it set to 60.9 now and am getting a single (3D) image….. but in Dirt2… headtracking only works when the VorpX menu is open (del key) otherwise it does not work, but can’t figure why not.
