--- Comment #16 from Ken Sharp imwellcushtymelike@gmail.com --- I tried downloading large game files over my 1Gbps connection with the following results:
Windows Steam on Wine 8.12 – started around 300% CPU going up to 1000% CPU Linux Steam – started around 300% CPU going up to 1000% CPU Windows Steam – never exceeded 50% CPU
However: Windows Steam couldn't grab the file at more than 150 Mbps for reasons beyond my imagination, so I limited the download speeds on all clients to 100 Mbps.
Windows Steam on Wine 8.12 – around 300%-500% CPU Linux Steam – around 300%-500% CPU Windows Steam - around 35%-50% CPU
(Where 100% = 1 hardware thread fully utilised on a 8c/16t Xeon)
So make of that what you will. I never saw wineserver get particularly busy.
Wine does use more CPU than Windows, but not more than Linux.
Does the Steam client use any Wine/Proton parts for its UI? I couldn't see anything obvious listed in an ltrace.
Bug?
