Let Roon upsample vs let Lumin T2 do the work

I've reluctantly invested in Roon for my Lumin T2.  I read somewhere to turn off all the processing in the Lumin app and let Roon do all the upsampling.  What's the benefit of that?  I figure my Lumin is built specifically for making the best signal possible. 

Secondly, my Roon core is an Asus ROG desktop computer, is it doing any work?  It's certainly not audiophile grade.

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?

Remember that upsampling is not real DSD. I mean, you can make more data, but it's fake.  It's not actually carrying any more information, but it will tinker with the DAC's mechanics, and change the noise profile.

Then how does one get real DSD?  Download each individual song from some online music service?
