Well... I do wonder if the windows filecache is having an effect here. If there's enough RAM available and the files had been loaded due to a previous run, or editor run, or from a write-cache during installation, you might not be seeing what really happens when data has to come in off the hard drive.
I was seeing the same behaviour on low IO drives, but, when I reduced system RAM to <8GB free (should be no problem if the footprint is 3-4GB), and again used my lowest speed drive (125MB/s), this was the result after a bit of traversal:

I was arguing just a few pages back in this thread (and for months before) that additional system RAM could be used to mitigate the need for an ultra fast IO in many scenarios and this seems to prove that point (with which not everyone agreed). Its not ideal obviously from a cost, or initial load point of view, but its clearly a viable solution for those without fast SSD's or until DirectStorage is available. DDR5 hitting the market later this year with double the density of DDR4 should make these RAM capacities much more commonplace moving forwards too.
These specs scream lack of Direct Storage, high RAM to mitigate the slower IO and additional CPU cores to mitigate the lack of a hardware or GPU based decompressor.
I'd love to hear what kind of SSD utilisation the demo uses both on initial load and then once the RAM is fully loaded up. My assumption would be that on high RAM systems, once the RAM is filled the IO requirements are pretty reasonable. But the less RAM you have, the higher they get.
For comparison 125MB/s is about 6 times faster than what Insomniac use (20MB/s) for their streaming engine on Spider-man (PS4).https://www.resetera.com/threads/unreal-engine-5-dev-workflow-stream-today-5-26.431627/post-65799137

I sure did, it is now corrected, thanks.Lol, what. From the video, think he messed up left and right.

like a flat out 1080p?Can I throw a random request into the ether for someone to play around with Series S levels of base resolution upscaled to 1080p. Really curious as to how that looks.

Would it be something like 480p scaled to 1080p or is that taking it too far?
