Sorry for the double post, but I’m also now finding a lot of visual artefacts with Nanite foliage in 5.2.1 (even after the hotfix) that were not present in 5.1 on NVIDIA hardware.
I had previously submitted a bug report for an issue in 5.1 (nothing came of it…it was never fixed as far as I know) for Nanite foliage flickering with the AMD 6700xt and 7900 XTX. You can see that here: Nanite causes flickering on foliage with AMD GPU, but not NVIDIA
However this is now happening in 5.2.1 on NVIDIA RTX 3080 and 2070 as well, whereas in 5.1 it was restricted to the AMD 6000 and 7000 series.
Have confirmed that this happens both on foliage assets made for Nanite (i.e., modelled leaf-by-leaf) AND on assets using Masked foliage. I think it may be related to AA (seems worse with TSR than TAA). Hard to say. It’s not quite as bad as it was on AMD hardware, but you can see trees fickering / jittering here and also how that stops when TSR is disabled by console command.
