Let Roon upsample vs let Lumin T2 do the work

Isn't the ROG a gaming computer? It should have the power to run roon with upsampling unless someone is playing a game on it. 

Roon is a little unusual in that all the DSP is done by the core.  So, upsampling and EQ and room correction happen there. If you are using a few EQ bands, with PCM to PCM upsampling the CPU is very little. On the other hand, upsampling to DSD can be ferocious in terms of CPU usage.  I use about 6 EQ bands and double the incoming PCM rate and my 7 year old AMD A10 CPU barely hits 5% usage.

Which to use?  I don't know, but not all upsampling is equivalent. The algorithms can result in different results.

T2 owner here using Roon. Yes, you use the Lumin app to turn off upsampling and do upsampling function with Roon. I've used Roon to upsample to DSD512 in the Lumin without any dropouts. If you get dropouts that will mean your ASUS server doesn't have enough computing horsepower. You may or may not like the DSD 512 presentation.

Yes it's a gaming computer with 16gb of ram and i7 processor.  It has plenty of power to do whatever, but does it do it the same as the Lumin?

@tuberist thanks for the input.  Why use the computer/Roon instead of the lumin though?
Also, why would one not like the DSD512 presentation?  Isn't that just higher quality or truer to the original?  Isn't it just a higher accuracy basically?
