I have a huge problem with optifine. The fact is that when I run minecraft with optifine, the game menu is completely normal (60 fps) but when I log into a server/map the game is at 0 fps but I hear the sound and the chat is not freezing too. I also can't activate the "lazy chunk loading" option when I press it. I tested with the all version of optifine and it won't work.
The thing is that when I log without optifine(vanilla or modded) the game run perfectly.
Please help me that's annoying !
I have a video : https://youtu.be/LRwcLeHLJc4
(my video is laggy because I record at low fps)
