Increasing Perceived Resolution
Hey all, long time lurker here... You’ve likely noticed that perceived resolution seems to improve while you move your head around with your eyes fixed at a point in a VR scene. While constantly th...

It is not impossible, but never perfect, to have a motion vector surface helps, but again, never perfect.
Sorry for the double post, but there is one more thing I'd like clarification on.
I looked into Temporal AA and it sounds like its slightly different to what I initially decribed. With TAA, a newly rendered frame, that is offset by a subpixel, is combined with the previously rendered frame before it is displayed.
If this is the case, than ghosting/smearing would be inherent to the technique. In other words, a "ghost" of the last frame will always exist within the current. Am I understanding this correctly?
By only displaying the newly rendered frame as I proposed, you might break the tie to the old frame and therefore alleviate a lot of that ghosting. However, this introduces greater potential for perceived flicker and jitter. This is where the higher refresh rate of the rift may be of use.
