Back after 2 years, game lag lags lagging laggy

[Woodrow]

I was unable to search the forums for the word "Lag" because it's too short a word apparently.

I started playing again after a couple of years, same Windows 10 system.

The crashes are worse, and the lag is WAY worse. My speedtest checks out fine so it seems to be the P99 client.

I don't mean low framerate, I mean when I'm fighting a mob and they run, the mob reappears somewhere else after a 5 second delay. Same with casting spells etc. there is a big delay.

Any known fix for this?
