hi @nandada, i haven't hit any snags on my M2 MBP
As expected am getting much better performance compared to my 2019 MBP. Load is around 50% when running 8x 1920x1080 HAP encoded videos simultaneously (with 1 out), with settings of target frame rate 30fps, general service 20x per frame and display refresh scaled.
My 2019 MBP would hit 100% load after running more than 6 simultaneous videos, so i previously used a target frame rate of 15fps
Have borrowed a couple of monitors to play with 3 out and will report back results soon
Rgds, Mr J
