I've used many different clients for Minecraft, including Lunar and Badlion. But for every client this message appears every few seconds in the chat:
Can this be fixed, or is my computer or Minecraft too bad?
Which Minecraft version do you use?
Check that your graphics card drivers are all up to date
Check whether OptiFine is up to date - update if not.
Make sure Minecraft only runs on 32 bit.
In addition, mods can cause certain problems. Uninstall or disable them to see if that solves the problem.
I mostly use the 1.16.4
Do everything suggested by me and then everything should actually work again without an error message!
* Ps don't forget to restart!
Is it possible to update the Optifine version of the client? Haven't figured out how yet.
