I guess we disagree Neil ... with current hardware 32c/64t CPUs, DDR5, M.2's, GPUs with 82 TFLOPS at FP16/FP32 is some serious computing performance ... where working with 5030 4000 x 3000 res files would barely register as "activity". My PCs can process 75GB/sec thruput (not theoretical) data no problem. When I'm editing there is hardly any CPU or GPU activity. I would expect Pr to have all my cores working to prerender whatever format it needs to display an image correctly in a sequence, but I get nothing until I move my playhead to a location then I get ONE CPU pegged at 100%. CUDA seems to be only used on exports or render outs not during editing nor proxy generation ... makes no sense to me? Editing is the #1 operation for me ... I assume most either send out final to a render farm or their own render servers (I use my own in house) so it's really not that big a deal ... it's the editing that's the problem. Even with photoshop, exporting a simple 4K image to PNG for some bizarre reason takes 10-20 seconds? Something that takes <1 second in Windows Paint/Photo app? Sorry, but Adobe have some serious performance issues that they can't seem to or don't think are important to solve? Software is not physical, tools are locked into the physical realm, can't really compare. Like I mentioned to Warren below, I think the issue is the use of abstraction layers in coding trying to maintain a single code path for both iOS and Windows. This is the LCD approach to software engineering across platforms, cheaper development costs at the cost of less utilized and highly specific accelerated hardware instructions. But again, if editing in Pr is going to be such a horrible performance issue, then the golden rule for software development is to provide the user with a "progress indicator" to shows users that it is working on something even if very slowly. Right now, there is NO visual queue (unless you're like me and monitor activity via task manager or some other tools) in Pr to indicate it's "thinking". That's just a bad UI. I honestly don't understand why some of you defined the poor performance of Pr? You know it's poor because you and I have work around after work around to try to improve it. I was taught to use the right tool for the job also, Pr isn't that tool.
