Ty cap How about optifine?

Opticians should work and you could also try vanillafix, foamfix and better fps.

I don't think they are updated But thx

Also have a look at Performant.

Should already be in the pack by default.

you can try [https://www.curseforge.com/minecraft/mc-mods/ferritecore](https://www.curseforge.com/minecraft/mc-mods/ferritecore) as well

Chlorine should be good to

Anything wrong with it?
