    Default Do Devs play games or test what they do ?

    Im running

    x.server x.org 1.7.2.0
    Kernal 3.13
    and Mesa 9.2

    I have noticed On Mesa 10.1 and above adding AA to source engine games slows the framerate to unplayable. Also On Mesa 10.1 the overal FPS is higher than 9.2 but it is not as smooth by far, also 10.2 is even worse.

    So the question I have is how can one make a change that ruins a game such as a source engine game and not actually play test to see if that was a positive change? It seems like a chef not tasting the stew before serving.

    So at the moment, I wont run Oibaf or Edgers just incase it screws the performance up, but i would like some Opengl support for newer games.

    I will have to ask: what do you think makes Source special. Sure, it's important to you, but what should make it important to dev foo?

    inb4 it's popular. By that argument everyone would have to test (and buy!) the top 10 games each year, including such shining examples as Minecraft or WoW.

    I dont see a problem with that argument. It's not totally out of the question to test your work it happens in all industries.

    now, do they test against a benchmark when complied at all? if not then there litterally is no testing other than a basic soak test. Which is appaling.

    noticed that is it actually the X.org Edgers PPA that slows down performance lots.

    1.7.2.0 is fine, 1.7.3.0 is slow and chuggy.

    anyone going to test and fix?

    We try and test as many cases as possible, but we can't test every combination of hw, apps, distros, kernels, drivers, and libs. If you are having a particular problem or notice a regression, please report a bug (https://bugs.freedesktop.org).

    for some reason even though i havent added a PPA i have now noticed a large frame drop and stuttering. So i checked

    glxinfo | grep "OpenGL version"

    and it was 10.2 again

    before this it was butter smooth on 9.2

    What's the easiest way to regress to 9.2 again please? All source 1 and source 2 engine games are effected.

    Also, i wont report a bug, it should be plain as day when the main games for testing TF2 (even phoronix has a TF2 benchmark) L4D2 et al.. are going much slower with 10.2. Why should I bother when 9/1000 i get no response for months and then smooth, and then slow and then smooth and then slow

    10.2 =
    10.3 =
    10.4 =
    10.5 =

    etc...

    this has happened for quite a number of years. It's the reason Canoical and Valve are taking their own approach and release schedules to stuff as there is no quality control in the opensource world. Excusing a few dev's who care and Torvalds.

    So what is the easiest way to go back to 9.2 please..
