Roon slower than other programs on my PC

Thanks again. Are you stating that Roon cannot run on a PC with HDD? It worked when I installed it?
Re a. The DAC should be Roon ready as I bought the additional board for the DAC that handles this. The settings page states (not sure how to attach a picture):
Networked (these devices have been found on the network)
roon ready
Mytek Manhattan II DAC
So I would assume that Roon can “see” it as ready?
Re b: I have version 1.4 (build 300) - the page states I have latest.

To dhusky: Yes the controller is the Windows PC. I am not sure why a “bad” GUI is working normally on everything else on my PC than Roon?

Thanks
