    [QUOTE=phoronix;381160]Phoronix: SteamOS vs. Windows 8.1 NVIDIA Performance

    For those NVIDIA gaming customers running Microsoft Windows 8.1 that have been thinking about giving Valve's SteamOS Linux-based gaming platform a try, here are some early benchmarks of the SteamOS 1.0 beta that compare the performance to Microsoft Windows 8.1 Pro x64 on multiple NVIDIA GeForce graphics cards.


    Windows 8.1 NVIDIA Performance,i think is good.

      For curiosity I've benchmarked the performance between both OS's using a resolution of 2560x1440 8xMSAA, all settings maxed. Using a intel 4770k + GTX680 + 8GB rig.
      I've reached the following numbers:

      Win8.1 - 235,82fps
      SteamOS - 153,65fps

      I tried to apply the following Nvidia optimizations in launch options but the game refused to start. LD_PRELOAD="libpthread.so.0 libGL.so.1"__GL_THREADED_OPTIMIZATIONS=1

      To simulate similar conditions I runned Steam windows client with -steamos prefix and Big picture mode.

        which game?
        directX vs openGL or openGL vs openGL?

          oops, forget to mention the game, it's Half Life Loast Coast. D3D on windows, OpenGL on SteamOS.

            Given the fact that different code path is used on Windows and Linux, testing a single game doesn't say much about SteamOS (or Linux).
            Never the less, I would imagine that D3D Windows only games that get converted to Linux will suffer from higher over-head that will most likely be far more noticeable as the FPS increases.
            160fps vs. 240fps is far less relevant than 40fps vs. 60fps.
