    Default Linux 3.7 + Mesa 9.1-devel Running On Ubuntu 12.10

    Phoronix: Linux 3.7 + Mesa 9.1-devel Running On Ubuntu 12.10

    For those Intel Sandy Bridge owners wondering if there's any worthwhile performance improvements when upgrading from Ubuntu 12.10 with Mesa 9.0 and the Linux 3.5 kernel up to the early Mesa 9.1-devel state with the Linux 3.7 Git kernel, here are some benchmarks...

    Default Doom3 36 fps

    Doom3 36 fps even at low setting, means that the opensource drivers are out of the question for most people who want to play the game.
    It runs really really well on my low-jitter kernel, with the closed source drivers though.

    Peace Be With You.

    You can play Doom 3 with those frames actually, but you also fail to consider the fact that those are from an Intel IGP. Please read the article rather than using it merely as an excuse to pimp an idea.

    You can play doom3 at 36 fps? Not really. You can get an idea of it, but the exhilaration of low-jitter 72fps it will not have.

    But it was intel. I assumed it was opensource nvidia since the fps was so low.

    So intel gfx performs that poorly. Well I appreciate the benchmark anyway.

    PS: Even my mac mini from 2010 plays HL2 ep2 well, and that is much newer. Thats an nvidia 320m processor. (2.4ghz core2duo). Carmack says doom 3 still stresses a lot of hardware, because of the 3 passes he uses to render stuff. Which is also why I linked to my low-jitter kernel, because it runs doom 3 well. (Better than windows).

    Doom 3 was set for 30 fps on console, so yes it is playable.

    Have you ever even played Doom3? It runs just fine at 30fps - as long as that's the minimum, and it's not consistently dipping down into the teens.

    Doom3 isn't a twitch shooter that requires 60fps.

    Default Jitter

    Admittedly I didn`t read that article the first time, but who even makes any h/w that runs a game from 2004, at 30fps. I am looking back at the article to see if there was anything I missed.

    Doom 3, at LOW setting 1280x1024 - 36/38 fps.

    What is this chipset? Something made for windows GUI? Sandy Bridge = worse performance than my mac mini?

    In January 2011, the Sandy Bridge processors were released introducing the "second generation" HD Graphics:

    i5 = the 6 "execution units" version?

    36 fps. lol. I don`t even think 72fps w/ jitter is good. I have reduced it on my local kernel though, so that most of it is gone. And then it plays great, and it is one of my favorite games, along with HL2.

    Doom 3 is also very jitter sensitive, so it is great to have it playing well on my computer. Carmack says it uses 3 passes for rendering, and some say it even can look better than Rage, where he only uses one. So it is a bit interesting to tweak my computer for it, and reducing jitter there, seems to improve overall computing also.

    Then with a GTX280 and a core2duo 2.5ghz, it plays extremely close to perfect, 72fps at max setting + 2xMS. On my current setup, I noticed just one "jitter" with some hd-activity, which maybe even that can be removed.

    If you have played it low-jitter and 72fps you think everything else is a bit lame.

    HL2 in wine, also plays much better on a low-jitter kernel, nearly as good as my optimized windows install (~100 threads). Also ofcourse HL2 on that windows, plays very smooth. Doom 3 on windows though, even highly tweaked is much to jitter-sensitive to play as good as the linux-version.

    I have also enabled the "jittered subsampling" (r_jitter = 1), which actually adds jitter, to it, but this kind of jitter increases percieved resolution. Which will not work well with low fps. Interesting option, which one can build some ideas on.

    Peace Be With You.
