This is absurd! The ROON windows app draws about 80 to 90W using my GPU.

What happens to your GPU if you close the roon app?

it runs the Windows GUI - even if you take the mouse over the HWinfo program it goes up:

@Apesbrain: Thanks for the link. This seems to be the issue. Roon uses openGL to render the frontend. I just do not understand what the 50x50 pixels animation is they are talking about. Also my high power draw also occurs when the app is only in the background. But

You see. Your GPU clocks down and that saves you 20W.

Looks to me like a very poor implementation of GPU compute. Instead of just doing that little bit of processing on the CPU, Roon is making the system spend a lot of cycles moving data to the GPU, do that little bit of processing, and spend a lot of cycles moving the results back from the GPU (left is from the screen snip in post #1 with Roon running, right is without).

From 2.5 GT/s to 16 GT/s is an increase of many 10's of GB/s of memory transfer. Below from Wikipedia.

Yea its absurd using a pc for listening to music. At least from a green point of view.

Oh dear, now I'm startled.

I have the default settings, Nvidia drivers - never bothered to look at it

How do you know its Roon?

I took OP's word that Roon was the only difference between the 2 screen captures. And I assumed that OP had verified that the effect was repeatable.

as I said, Windows and any app with a GUI is using the GPU
Not so easy to pin-point the GPU usage, as it varies

I recently noticed that my PC was consuming a significant amount power. I found out that the problem is the roon windows app (not the server, just the windows client), which draws about 80 watts using my GPU.

Also my high power draw also occurs when the app is only in the background.

Mining Bitcoin?

I doubt if he would be concerned by the power consumption in that case

I was guessing that Roon is doing it without his approval

I had malware doing that exact thing in the background. Not impossible.

Wow. I'd definitely be wanting a cut/return on my annual investment there. Unless it is malware...
But I guess seeing as Foobar is free and using 8W plus minimal resources, I will just watch this thread smugly...

Tho I am actually curious to know what Rune is doing that is so power intensive...

I replicated the shift from high power drown to low power draw 20 times already. It is the roon app. And the reasons seems to be that they implemented the gui using open gl. But did a very poor job doing so.

I was hoping that other users can replicate this behavior and maybe find a fix or workaround.

This is just not a normal behavior and nobody would assume that just leaving the roon app open would draw that much power.

well, if you think it's not normal then you better post your findings in the Roon forum

Good idea, I was going to suggest that too. And if something comes out of it, please report back to ASR so we know about the problem.

Do this and choose integrated graphics for the Roon application..

I can report similarly underwhelming efficiency on my MacBook Air (2019, Intel i3, basest of base models). Approx 20% GPU while the app is only displaying the playback activity between a separate Roon server and a Pi+dac streamer.

As for reporting on their forum - You can try, but... temper your expectations. They moderate actively (a laudable practice) and seem slightly uninterested in customer feedback about the core function of the product (although in fairness, they did incorporate one of my minor UI suggestions.)

I quite like Roon, but I imagine dealing with a customer base of neurotic audiophiles of widely variable technical acumen must be taxing.

That is really an excellent tip. This should solve the issue.

I tried it but it does not to reduce the GPU power draw. My NVidia control center looks a bit different and has different option. I will try to make tinker with this a bit more.
