You bring up some very valid points, and those topics have been long-running discussions here on the forum. Everyone wants all of their computer's resources to be fully utilized to speed up any bottlenecks, but there are sometimes technical (and sometimes harder to understand) reasons why PD doesn't do that.
I agree that if you decide to use shadow files, that PD should generate those ASAP. However it seems like the programmers also want you to be able to do editing while they process in the background, and there's no way to force it to prioritize that.
One way to get somewhat faster editing and producing performance is to ensure that PD has the highest priority in Windows. To do that, open Windows' Task Manager and go to the Details tab. Scroll down until you find PDR.exe, then right-click and set the priority to High:
You may also want to do this for PDHanumanSvr.exe and PDStyleAgent.exe, as PD requires both to run. You can also choose to run one of these 3 processes in Realtime mode, so try that setting and do some editing to see if one of those running at the highest possible priority will speed up that project more than the others.
Note that these settings must be set manually every time you start PD.
There is another approach to speed up PD by having it use lossless (basically unencoded) video clips. All camera videos are highly encoded to get as much A/V information and quality into the smallest possible file size. It's pretty straightforward to play everything back, especially since the encoded clips are all optimized to do just that.
However, working with an editor requires the program to continually decode the source clip frame by frame, which often means it has to go back many frames to get the "B frame" (which has most of the detail for that section) and then read every successive frame from there to the current location just to fill in all the details, which can really slow things down - especially if you have edits like lighting corrections or FX applied. This Wikipedia
article may help explain the issue.
So, if you first convert your clips into a lossless format (like MagicYUV, HuffYUV or Lagareth, for example), they will contain nothing but I-frames, which are perfect individual pictures that don't require any additional processing to display or edit. This will allow you to work on the full resolution clips easily, but for some UHD clips (4k, 5.2k), it still may be useful to turn on shadow files (I need to on my 4 year old i7-4770k machine, at least).
The only downside (besides initially converting) is that the files can be 3-10x larger than the source clips, and you absolutely need large and fast SSDs to use this method. Obviously, your system is ideal for this, though
I have more details on the steps in this
thread. Hopefully, some combination of these tips will get you the fully powered editing experience you're after!
