This clearly needs to be optimized, my spec is AMD FX-6100@4,2Ghz, 8gb ram, Gigabyte GTX980 G1 Gaming and Oculus Rift. The GPU usage is just 12% and I can´t get more then 14 fps no matter what settings I try. The CPU cores isn´t used so much either so I can´t find any bottleneck. AC runs extremely well in VR with maxed out settings and so does project cars. I hope it will be improved because this is my favourite racing sim!
