I enable upsampling to DSD 512 and got this error msg “An audio file is loading slowly. This may indicate a performance or hardware problem” after few seconds of playback. No issue with DSD256.
Music source is from local SSD, format is 24/96 and my CPU is Intel core i7 7700T and 8GB DDR4.
What is the processing speed indicated…if it’s below about 1.4 your system might be the bottleneck, but as you noted it’s an i7-7700T it’s should be enough.
What DAC are you using and what drivers wasapi or asio
“1.4” refers to the processing speed. You can see what yours is by looking near the top of your signal path. There’s some info in the Knowledge Base here. Scroll down to where it says “Pay attention to CPU Usage.”
Use the processing speed indicator to get a sense of how “close to the line” you are. Numbers below 1.0 mean that the CPU on your Roon core is not powerful enough to execute the configuration you’ve requested.
I’ve seen screenshots of Roon upsampling Redbook to DSD512 on an i5. I would have thought an i7 7700T would be fine. Let’s drop a flag for @brian and see if he can spot any issue here.
