Original GitHub issue: https://github.com/jpochyla/psst/issues/289

Describe the bug
psst-gui.exe is using ~1% CPU when idle, up to ~3% when playing a song.

To Reproduce
Run psst.exe on Windows

Expected behavior
CPU usage should be much lower (Spotify is using ~0.5% when idle, ~2% when playing a song)

Screenshots

Environment

OS: Windows
Version: latest (can't find a version number)

Additional context
There seem to be 2 threads using the most CPU -

psst-gui.exe calling KernelBase.dll!WaitForMultipleObjectsEx
psst-gui.exe calling user32.dll!GetMessageW

I'm running it on Windows and I can't observe this. The official spotify client consistently uses more CPU.

Hi! Thanks for the report, unfortunately I don't have the resources to tackle this kind of Windows issues. A few % +- to the official client is acceptable at this stage of development, so I'll close this, hope you don't mind. Performance will only get better in the future.
