Optifine is a very important mod, right? Impossible to use it on Aternos?

Yes, Optifine is just one of the most important mod, almost vital, even recommanded by Conquest Reforged which is available for Aternos.

But even if Conquest Reforged is available for Aternos, Aternos doesn't support Optifine? (I read "we don't support this platform")

Any way to make Optifine work?

Thanks!

Thank you for your quick answer.

So, Optifine work, am I right?

You confirm that Optifine work when using Aternos server, if I understand well?
