can use optifine?

I believe that optifine is currently against the rules across the board on all minecraft speedruns, so that would extend to Terra Swoop Force as well

hmm ok so to be safe should i use fabric instead or just vanilla?

to be fair, I used optifine in my runs and they got accepted... 🤔

I'm planning on making a post about this shortly: Optifine is ok in my book because it's a pretty beefy game to run on some PCs, but we're against using fullbright.

Technically in sr.c, TSF is a different game than MCJE and has different moderators that have their own authority separate from each other.
