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.
If I close the windows app my computer needs about 60W (measured with Shelly Plug via Home Assistant). If the windows app is open and playing a song, then the computer's power consumption increases to 150W. You can see this in the history in Home Assistant.
Via the program HWiNFO64 you can see the increased power consumption (“GPU Energieverbrauch” 15.5 W vs 71.9W) of the GPU (RTX 3080).
The roon server runs on a Linux server with a small library of about 20k titles. The music is streaming directly to a Google Chromecast Audio. So the computer actually has nothing to do with the music playback.
I think this is absolutely absurd that the Roon Windows App costs me 80W to 90W of power not doing anything.
Does anyone know about this phenomenon? You can check for yourself using the HWiNFO64 program. You can see directly that the GPU needs extremely much power as soon as the Roon Windows application is open and plays a song.
EDIT:
There are some reports on the roonlabs forum about high GPU usage with the roon app.

Roon 1.8 use a lot of GPU when the animation icon of playing can be seen
Roon version 1.8 (build 970) stable, on a mbp 19’ I found roon use all of GPU resources when playing, and the playing animation is moving. I found that it only happened when the icon is in viewport.


macOS Catalina interface laggy randomly while running Roon (High GPU usage randomly, Roon idle 20% GPU, sometimes up to 99% usage) [Resolved in Roon 1.8]
Hi @mavmcl, I had a chance to discuss this case further with QA and they have confirmed that they’re able to reproduce this behavior in the lab again, thanks for the secondary desktop suggestion . We have a theory regarding OpenGL as to what might be causing this, and we’re investigating this...


Roon 2.0 interface unusable on Windows 10 (Xeon CPU / Nvidia FX580 GPU)
Thanks for your reply Robert. My PC does have OpenGL 3.3 installed and running. Is this version of OpenGL compatible with Roon? I don’t have another PC or laptop I can try at this time. I admit, my computer is getting a little long in the tooth but it does run Windows 10 and every other program...
