The new 1.16.200 completely ruined minecraft for me.

The beginning message said the game would just have a few bugs if i didn't update the driver on my computer. However, the new update made the game extremely laggy. It now takes an average of 7 minutes to load in and out of a world, and no, this is not an exaggeration at all. when i'm in a world, the game is laggy but not a lot, but when friends join my worlds, i might as well have summoned 30000 withers, it's so laggy. It's not just in the game that's laggy, either. Minecraft itself causes my entire computer to lag now. The bars at the top and bottom take like a whole minute to appear when i put my mouse there, and it takes like 30 seconds for the game to actually close. Now, are you ready for the absolute worst part? THE ENTIRE COMPUTER FREEZES WHEN I CLOSE THE GAME! I can't even close minecraft without having to force-shutdown by computer by holding down the power button. I'm not usually this intense, an not trying to be rude, but i am literally shaking with fury right now. I will try the driver update thing later and see if that helps, but this is about 50 times much worse than you described it in the beginning message. i can't even play the game. Also why did you change the title the first one was more true
