Known Issues - Lord-Akkrand/Skyrim-NX-Toolkit GitHub Wiki

Skyrim itself (even of PC) has a loop issue when loading plugins. Having a lot of plugins WILL cause lag, you can use zEdit to merge plugins together or you can overclock your game.

Utilizing bAllowCreateGrass=1 will cause all grass to rotate due to limitations with the Switch version of Skyrim. We recommend not to use any grass mods.

Converting landscape textures will result in artifacts (black dots on landscapes). The tool we use to convert textures to Switch format doesn't handle landscapes properly.
