Is the Use Local Files a NAS?

Actually the Image Upscaling is the biggest offender with the 21ms. Or well, at least its the rendering step that includes the Image scaling, but dithering isn't going to cost that much. :)
The reason is probably that the image is _almost_ 4K but not quite, which is the worst case for scaling - you have lots of input pixels and lots of output pixels - lots of data to process.

marko, in the same dialog terrym@tassie showed above, in the JRVR settings under Scaling, you are currently using Jinc as the Upscaling Algorithm, maybe move that up to a different setting - they are roughly ordered in performance/quality order. Worst case you end up with one of the two built-ins which are a lot faster.
As a second step, maybe go to the Processing tab and disable Debanding. It has little effect on high quality content but can cost a bunch of time.

If you want a single easy option, you could also swap to the Performance preset on the JRVR General page. Although swapping the upscaler should do the job.

What graphics card is that system using?
The CPU performance from the benchmark looks fine, but it doesn't measure graphics performance.

No. I want to try NAS, the theory behind them sounds really useful, but around MC and the way we use it, they seem to cause a myriad of different issues that have me believing they can't all be down to poor setup, can they? So, I decided a while back to never go there.

I have an Addonics case (thanks glynor (hope he's keeping well)) that houses five HDD that are presented to Windows (MC server) via USB3 as JBOD, and in turn, DrivePool combines them all into a single 29Tb drive and presents that to Windows. This has worked very well for me for a very long time now.

That drive is shared with, and mapped, on the HTPC, to leverage the benefit of the 'use local files...' settings there.

People sometimes think a NAS is better because it isn't a computer, but that's not the case.  They usually run Linux.

And they have their own set of issues.

Can you test a local file without using that device?   Your problem could just be related to reading the files.
