Removing continuity allows me to use the 256x.

Your GPU does not support Patrix x256 due to maximum texture size limits.

But I can run the 256x without the continuity mod?

Continuity loads textures that vanilla does not load to allow for connected textures, thus increasing the total amount of textures that need to be put in the atlas.

I've encountered this problem too. My graphics card is Intel B580. What's your graphics card?

You ignored all the 256x warnings and didn't ask in Patrix help? There's info in the pins and on every Patreon release that tells you why this will not load on AMD/Intel GPU!
