M1 Pro, TBC, Lag

I have a fully updated M1 MacBook Pro 16 gb ram, and am playing tbc classic.

I have issues where, after about 10 minutes of playing, my screen will freeze while the game continues going.

My fps doesn’t drop
My latency is fine

It’s worse in dungeons than questing. I will be hitting a mob and standing there waiting for my next hit and then suddenly 2 hits and a spell go off (ret pally) like the game is catching up. Oftentimes when mounting the spell will appear to finish, I can move my character but it won’t mount for a few seconds and then suddenly it will mount and I will have moved to a new spot. All of my keyboard and mouse inputs happen I just don’t see them on my screen sometimes.

This happens when connected or disconnected from power, it happens when I am connected or disconnected to a external display. This happens with and without bluetooth/wireless/wired mouse/keyboard.

any advice would be awesome.

It’s a known problem which is extensively discussed on this forum. Blizz response is that it may be fixed in 9.1. You can read a book or play something else.
