it is really prevalent on finalized assets and scenes in our project at work (can’t show anything atm tho)
I think PCSS will be just a high-end feature as shadows are already expensive on their own (i.e. wouldn’t solve the problem on mid/low-end PC’s), and if anything I think it would only solve the issue at very close range (I don’t expect PCSS to be usable at all distance ranges on full-scene Cascaded Shadows)
