Yeah - seen a lot of comments on that. As for me, no - not really any problem with shimmering that I’ve noticed. I did play around with antialiasing … FXAA does get a bit more performance but pretty bad shimmering (you have to imagine it’s the effect of heat haze 
). TAA is much better, and seems to be manageable now.
For what it’s worth, I found motion reprojection caused all sorts of ‘tearing’ and ‘wobbling’ (for want of a better description) in the scenery as well as the propeller artifacts … the main reason I didn’t like using it even though it can do a good job of smoothing the display.
EDIT:
Just checked … only place I’m getting significant shimmering in VR is around very thin model items (poles, railings etc.) against a distant background (as ringed in the screenshot, SBGL). Elsewhere, nope, pretty steady
(Screenshot is 2D … so a little better than what I get in VR
)
EDIT EDIT:
Specifically on anti aliasing in VR, if anyone hasn’t found it yet - see this thread.
