I've also been having the same issue for months! I've changed all the anti-aliasing settings that are recommended on other forum posts/reddit. I've tried windowed fullscreen vs fullscreen. I've turned off/on edge smoothing and post processing effects. I've tried dx9 and dx11. I've also tried to use SMAA and FXAA in gshade...none of these things have done anything, unfortunately. The edges of objects and sims look great, it seems to be an issue with lighting or shadows? I haven't tried to remove the dynamic shadows because, honestly, I don't want to haha...I'd like if the game could look good and still have dynamic shadows at the same time if possible :)
