When I play modpacks with lots of mods, I get block lag and entity lag but im still over 60fps. It's like I'm in a server with a bad connection. On other threads, the answer is, "Get a better computer." No one seems to have a fix for the game. It's not my pc, its an i9, GeForce 2080 RTX super, 32gb of RAM, and 1tb SSD.
