I know this might not be the exact situation people on here deal with, but, I lag out a lot, yet, I have a gaming pc with high enough specs to run Minecraft. It lags out without optifine. If I have optifine, it's just fine, BUT, 1.13 doesn't have optifine yet, and it's really, really annoying for me to play with the current fps. I get around 10 fps instead of my usual 60, which is, I must say, a big drop.
Does anyone have any suggestions?
**EDIT** I just fixed it! After a few searches...well, it's the discord overlay causing the issue! Apparently it makes your pc go nuts or something somehow!
