Hi, this shadow issue is probably already known, but I thought adding another screenshot might help.
For me, the 2k mod + 1x is unfortunately not sharp enough (2k screen). 4k mod poses major problems with shadows appearing randomly on the ground, and using 2k resolution + EMU also causes shadow issues (especially when moving).
I tried 1800p and 1900p (still better than 1440p), but my game systematically crashes after 30 minutes or an hour.
I should point out that Ryujinx and OpenGL are unplayable on my side (otherwise I would have changed).
I can only use Citron / Sudachi + Vulkan to have a perfectly smooth game.
I took the screenshots without the 60 fps mod so as not to add any other potential issues on both towers.
I'm using the latest version of the LOD mod (even without it, the issues remain the same).
