Hello, this also happens on a totally unmoded game for me, basically when I walk around grass shadows suddenly appear and disappear.

@WarDaddy did you go in your ini file and try to look at the shadow values?

I got mad and reinstalled the game, and even without mods it was still happening, so, basically having transparency multisampling with aa caused this, if you turn off one of them no nice looking grass, so fuck it. Installed enb and disabled shadows. But my system couldn't handle it at 1080p, I had to drop the resolution to 1360x768 and now I got it all at 60 fps. Only thing that looks a bit weird on lower resolution is the ui, but I don't mind since I'm playing immersive lol.

BASICALLY THERE IS NO SOLUTION WITHOUT MODS LOL BETHESDA PLS
