    Default Running The SteamOS Kernel On Ubuntu Linux

    Phoronix: Running The SteamOS Kernel On Ubuntu Linux

    It is possible to install Valve's SteamOS modified Linux kernel onto an Ubuntu Linux installation, but I would recommend against doing so, at least for now...

    well it's also about latency, for example Xonotic feels a lot better with a low-latency kernel on my sys.
    despite having about the same framerate!

    Does P-State apply to AMD gear?

    Yes. http://en.wikipedia.org/wiki/Advance...ower_Interface

    On AMD it's known as PowerNow! or Cool'n'Quiet.

    Straight FPS numbers don't tell the story. There is a certain minimum frame rate requirement, but beyond that the latency and responsiveness is far more important.

    How cool would it be if phoronix were to somehow measure and report those important factors? There are such benchmarks out there, and it would seem logical to use them any time we're discussing gaming/multimedia applications which have latency and responsiveness requirements.

    I always disable Cool'n'Quiet and that kind of stuff in the BIOS.

    Yes, this would be very useful. Input latency is very important factor in gaming. I will happily sacrifice some FPS for lower input latency. Most likely Valve have used real time patches to lower audio and input latency.

    Would've been useful to benchmark Source engine titles, and a slew of the latest and greatest titles available for linux on Steam (like Metro Last Light). I'm sure they're tweaking the kernel for latency and for games available on Steam; so none of the titles benchmarked here.

    I agree. This should be tested in some way, but I suposse it's quite more difficult and maybe it requires special hardware.

    What about the same tests with the same kernel and P-state enables? And 3.13 with equivalent patches and P-state enabled too?
