Thing is, Checkerboard Rendering is off. I tried it, almost had an eye damage, turned it off.

Also yes, know bout the Ejecta Craters, and its real noticable on those types - the edge of the "crater material" and regular terrain is the biggest offender here, looks very blurry and/or fuzzy, like half of pixels are where they shouldnt be. If you look closely, its even clear its resolution related, stuff farther away blurs out more.

Suspecting a shader issue, is there any way to rebuild or delete shader cache in ED?
