Not entirely sure what's happened in the recent past on my desktop machine though it MAY have been updating from 2019 to 2022 Ultimate (haven't tried 2019 as an option yet so will give that a go shortly) but just lately whenever I've started to create even a short video, importing loops, for example, to run alongside a music track whilst the audio plays fine, the videos on the timeline won't run for quite a while, then play as expected for a few seconds, then stall again, particularly when the track gets to a join/transition with the nest vid.
Looking at the performance of the task manager it doesn't seem to be a memory problem (16GB installed) and everything else seems to be running within expected parameters (though I'm not as au fait with modern PCs as I used to be - getting on a bit!!

)
Any thoughts on what else I might try to see what's causing this very frustrating state of play??
Cheers
