Understood. Once I change that mod, no other problems should arise, correct?

[Josh Mackenzie]

Also, given the mod author's current update schedule, it is mostly likely that there won't be an update for another 3 weeks. Do you think going back one, two, or more updates could help?
Thanks in advance.

The mod has been updated, and I tried using the updated version, but it crashed during loading. Debug.log :https://gist.github.com/DexTGS/c952c9c400be6b141a04146d58cdff18

Are you sure you read the whole document? I was at the loading phase right before "Freezing Data," when the screen grayed out and a pop-up read "Java System SE Binary (or something like that)" is not responding, and waiting for it to respond was of no use, and when I closed it, I received a crash report from the Minecraft Launcher.

By while I mean not the entire document was loaded, there is an option to see the rest at the top of the Gist. As far as I understand, the last few lines are the most important.

Should I remove OptiFine?

Another two questions, if you don't mind. Firstly, my display is 4k resolution, and obviously, you do not want to run Minecraft on 4k unless fps is in no way a problem. However, for me, turning down the resolution down to 1920x1080 and turning on fullscreen quadruples/quintuples my fps, however it stays at its low value when I repeat the same process with mods installed. Is this intentional, or is there a certain mod interfering? Secondly, what are some good performance-boosters for 1.16.5 forge?
Thanks in advance.
