Why do my shadows look like this ?

Hey to everyone,

I just can’t find the error why all my shadows flicker so much at the edges. The problem only exists when I use Virtual Shadows. Does anyone of you have a solution to make the shadows look normal without me having to switch directly to normal shadow maps, because then the shadows look subtly “bad”.

What type of AA are you using? Did you turn off TAA/TSR?

Currently I use FXAA

The edges of shadows using VSM are rendered using SMRT. This technique requires TAA/TSR for denoising. If you don’t want to enable those, you can also disable SMRT, but this also disables soft-shadows.
