Whenever i load up the mod with optifine 1.16.4 HD U G5, everything appears invisible at first then the world pops in and out of existence very quickly and makes the thing unplayable. in the video i have only futurecraft and optifine in my mods folder and i give a look into my optifine settings aswell.

Does futurepack even need to be installed? is forge + optifine enough? I am askign ebcuase optifine is known for render glitches with modding + they dont care about the modding community.. Forge has often offered the will for collaboration and fixing this but optifine never did.

Optifine with forge does not do this. its only when futurepack is added that everything goes wonky.

i turned off these things it was acting normal. I dont know which option was the one to fix it but its one of them.

nvm it was anti aliasing that was messing with it. The other options can still be used, but anti aliasing needs to be off for some reason

I heard optifine had an update that fixed some render issues, does this work now ?
