Quote - I have my shader set to 1.05 and sync.

I'm finding that if I set the Filter rate higher (it says to raise rate for anti-aliasing)
I end up with a scattering of pixels not rendering, leaving holes in the render.

Have you noticed this too?

 You mean the Post filter size? I've never changed the Post filter size but left it at the default setting 1, only changed from box to sync. The Min Shading rate is set to 0.2 and the Pixel Sample at 12.   But I'm going to test these next time I'm doing a render. Will see if I get the same results as you've mentioned.
