OK, fair enough. Or it might be the lack of single-core performance. Whatever the issue is, a Ryzen 5 5600x with 32GB RAM and GTX 1660S 6GB graphics should work well with the latest Premiere Pro.
I have secured a 5600x when they were available, but still waiting for the go ahead from the customer. He's still trying to get a decent answer from Adobe, initially they said his 1080p footage was 4K(?) so he needs 32GB RAM! Everything I read basically says extra RAM improves rendering times, should not affect timeline playback and Task Manager shows less than 8GB memory usage during the stuttering.
