I found that if I go to level 1 to track movement I have to pause repeatedly to, I guess, let the video catch up. I don't use 1 very much anymore using it mainly to look around. My system, on occasion, will still freeze on level 2 but I found that if I just wait for a few seconds, sometimes up to 15-20 seconds which can seem like a long time when you are waiting, that the video will catch up and continue as normal. Don't know if that makes any sense or why it works but it does for me. I still have the best video settings but find that the more scenery intensive the more processing the video card has to do and the greater chance of a freeze. Perhaps the new engine they are working on will solve the problems.
My computer has the save specs as yours except it is a 2017 Imac Pro with a 10 core Xeon W, and the Radeon Pro Vega 64. I just upgraded to Ventura so we shall see. Good lick!
