When I fly in Minecraft, I get bent back permanently. And when I sprint I fly weird. Which attitude is wrong? Video attached
If the whole thing happens on a server, I assume there are problems with the Internet. Otherwise it could be due to a bad graphics card. Otherwise try a different world. If necessary reinstall Minecraft…
I've never seen that before
As LuGaming already writes, either an internet problem that you are bugging around (if you are online) or your computer can't keep up with loading / generating the chunks… Can be a RAM problem (too few allocated) or simply performance too weak…
It's only since today. Runs is stable for half a year
Well, maybe something is running in the background that is currently eating up a lot of CPU power? Win updates e.g. Or something like that. Is it local or on an online server?
You have a cheap / bad hacking client.
