Smoothness in the head tracking is what ATW is responsible for. Can you confirm with the 1080 that you don't get blurring/juddering/ghosting when flying over objects like houses and vehicles? I have 2 980ti's and while I know that VR doesn't support SLI at the moment I get no difference in running maxed out or running less than maxed. The view is pretty much always smooth, but when flying the A10 low and over buildings or objects I often get ghosting on the object while my head tracking feels just fine. Framerates during these occurences are generally down at 45fps, yet smooth. I'm curious how much of an improvement the 1080 is and if I maybe will be upgrading in the coming months to the new ti/titan once released.
