TAA significant performance drop vs 2020

I’m finding the RdrThread goes through the roof in VR.

I get 60fps in 2D but only 18fps in VR, using around the same render resolution (1680x1050 vs 1645x1827). Yes, this is rendering two views instead of one, however the RdrThread timing is almost 8 times longer!

Another thing that makes me wonder if it’s an optimisation issue is that if I use DLSS to lower the render resolution to just 823x913, RdrThread still takes over 50ms and the frame-rate doesn’t really increase from over four times the resolution.
