Big Sur lag when typing

I have MB pro 16, after update to Big Sur, its started to lagging when typing... sometimes lagging more and sometimes does not lagging at all. But this happen even in terminal at RESTORE option at startup! It's look like im using old like CPU i286. Do You have same ISSUE ???

I already tried to reinstall the Big Sur, with formatting SSD and WITHOUT restoring old settings.

And this DOES NOT HELP ME :-(
