My Singleplayer is lagging really bad in every version (in 1.8 less than in 1.17 but I'm shure its not normal in every version).

For example in 1.17 with Optifine I have 200-500 fps in a minigame or lobby on a big server and 9-21 fps in Singleplayer. Before my Minecraft crashes in Singleplayer my fps drop to 0 and the percentage of ''Memory'' shown by pressing f3 go to 100. As I said in Multyplayer really nothing like that happens and i have many fps in comparison. That's surely not normal. I don't really know since when my Singleplayer was ''broken'' but i think for a long time (I didn't use it in a while so I didn't see the bug).

Btw I wrote 1.17.1 for the bug because there is no ''all versions'' Option. (The bug is in all versions.)
