All I have rn is optifine, and isn't that banned/getting banned? My fps is very sub par without it and I'm wondering what I'm allowed to use.

Optifine will be banned for 1.16+ coming mid-August. In lieu of the ban, we are allowing the optimization mod "Sodium" with fabric in 1.16+. We would really like to ban Optifine for other versions due to how it messes with the game in uncontrollable ways but there aren't any good optimization mods for 1.14 iirc

Oh and btw sodium runs like 6x faster than optifine lmao. AND it also doesn't screw with the game in bad ways

Unrelated to the original post but I like the idea of banning optifine from 1.16 even though I haven't tried sodium yet, it does mess up quite a lot with the game (e.g I once had a dragon that would disappear while pearching), optifine for 1.14- was great tho, because it was complete and they totally changed the way the game worked on 1.15 from what I remember which slowed down optifine's progression quite a bit
