so I recently pb'd after a lot of work in the RSG category, and my run was rejected saying fabric API is banned. is there another good FPS booster that is allowed? if yes please send a name or a youtube download explanation video. Thank you!

Ok

Use Sodium, lithium and/or Phosphor, they do not require fabric api

Oh, I didn't know it could still work and boost my fps without API, Thank you!

exactly the same situation w/ me. im very sad cuz I got pb today and after that I knew that I had fabric API and its banned(actually my former run was rejected just yesterday, of course I realized after my pb)
i hope we could get better pb run soon!
