This looks like a very nice performance mod but It seems to not run well on Fabric. I experimented on a test profile that uses only some of the mods I normally have. When using shaders the FPS drops bad when It normally runs fine with them, like 40-60. And during this specific test when I turned them off the game crashed. Logs attached. The weird thing Is that It works fine on a Forge profile, shaders and all. Same world In both loaders
