SteamOS Gaming Performance Lags Well Behind Windows (arstechnica.com)
New submitter NotDrWho writes: As reported by Ars Technica: "With this week's official launch of Valve's Linux-based Steam Machine line (for non-pre-orders), we decided to see if the new OS could stand up to the established Windows standard when running games on the same hardware. Unfortunately for open source gaming supporters, it looks like SteamOS gaming comes with a significant performance hit on a number of benchmarks." They tested with two graphically intensive titles from 2014, Middle-Earth: Shadow of Mordor and Metro: Last Light Redux. They say, "we got anywhere from 21- to 58-percent fewer frames per second, depending on the graphical settings. On our hardware running Shadow of Mordor at Ultra settings and HD resolution, the OS change alone was the difference between a playable 34.5 fps average on Windows and a stuttering 14.6 fps mess on SteamOS." Even most of Valve's own games took big performance hits when running under SteamOS.
These tests were done on their own custom built steam machine from 2 years ago. (Mentioned in article)
They have an older video card and older CPU than any of the steam machines for sale.
I'm guessing most optimization work has gone into the latest nVidia series rather than 1-2 previous ones.
One of my primary suspects for the difference is the video card - how well optimized are the Linux drivers?
Actually, it is has been shown that on the same hardware (with NVidia card) for Metrox Redux it is just a question of SSAA being on or off.
Who really expected the same or better performance at this point?
I do.
...but I got the sense that Ars Technica pretty much sucks Microsoft cock all day long.
This is based mainly on their attitude toward the privacy issues related to Windows 10, but I noticed other corroborating data points.
