    Indeed, composite slows down games quite a lot, at least on my box. KDE "should" disable kwin effects, but it seems it's not always working.

      Are you saying KDE does turn off kwin effects when running a game? Does anything do this, does Windows do this automatically?

      This is a really interesting idea to me --- that there is some contextual dynamic system profile... so when I launch a (high performance) game it signals to the OS to move into game mode which turns off effects/compositing desktop, perhaps de-prioritizes non-essential processes, etc. so that your game runs as a fast as possible with no intervention.

      Equally VLC could switch to movie mode which would perhaps mute other system sounds and set IM to busy automatically. (all of this with a nice panel app to tweak the profile for special situations where even if you are watching a movie... that expected call from your friend would come through on skype, and all the rest to voicemail.

      Context sensitive computing with a UI to make it easy to customize those edge cases / unique situations.

        KWin is supposed to switch off compositing when a full screen app has taken over, like a game or video player. Compiz also has an option to do this, although i don't remember what the default is.

        Windows definitely can do this, but i don't know if it does. For some reason I'm thinking it doesn't, but I could be wrong. I remember when Vista first came out there were occasional programs that would cause compositing to turn off when they ran - like Java apps maybe, or OpenGL. I think that issue is pretty much solved, although I'm not sure by who - either MS fixed Windows, or developers fixed their apps to work better in windows.

          Ubuntu used to ship with this option enabled in Compiz (unredirect fullscreen windows) but they disabled this in recent versions. Good thing, too: if you disable the compositor for fullscreen applications, then you'll get god-awful tearing and artifacts whenever a pop-up notification shows up on screen (whenever you e.g. try to change the volume through the keyboard or you get an email or whatever). I'd take a slight performance penalty over artifacts any day of the week.

          If I cared about the extra n% performance that much, I'd simply disable the compositor completely.

          Note that Windows still disable Aero for *some* fullscreen applications. I haven't managed to discover how they decide to do that, though. It might be driver-related, because for the same application, my nvidia laptop disables Aero while my Ati desktop doesn't. Go figure.

            I think Windows just disables Aero when there's a fullscreen DirectX context somewhere. Possibly when there's any DirectX context. On the Linux side you can enable "Unredirect Fullscreen Windows" in the CompizConfig Settings Manager though it's been a while since I've tested its reliability.

              Kwin is supposed, but is not doing it. When I had slower graphic card I had to turn off Kwin composite. Problem concerns especially games on wine (eg. Settlers), I run them mostly in window, so Kwin can't detect fullscreen application (if it can at all...).
              Compiz have extension unredirect_fullscreen_application, but works poorly and is (probably) turned off by default.

              Some aplications, especially benchmarks like 3DMark, turns of Areo on start up. Some games too, but on Windows Aero with fullscreen games works much better that compiz.

                It can't be that simple, because fullscreen Mass Effect 2 does not disabled Aero (while fullscreen Mass Effect 1 does). The app I'm testing uses fullscreen OpenGL and it seems to behave differently on different systems.

                My best guess is that some games try to avoid this strangeness by not using "real" fullscreen mode. I'll have to try this hack myself and see how it works out.

                "Unredirect fullscreen windows" in Compiz works fine but causes issues when tooltips appear over the undredirected window. This is probably why recent Ubuntu versions ship with this option disabled (I recall it being enabled by default around 8.04/8.10 or so).

                  If possible,
                  can we please get comparisons with less emphasis on 3d acceleration/gaming?

                  Thank-you.

                    I'd be interested in the performance comparison if on the Windows platform the mandatory protection has been installed (anti-virus, anti-malware). And the same tests after an installed platform has been used for 6 months. Windows is notorious for accumulating "crud" slowing down the system within a few months.

                      True, true, but still the differences that the banchmarks showed are enormous, it needs tons of crap for windows to become as slow as osx.

                        Nothing magically accumulates unless you install it.

                          lol to compare windows performance with real oses is meaningless actually

                          Do you get that there might be a reason why on the client Windows is over the 90% of the market share, OS X around the 5% and Linux about 1%?
                          If Haiku was installed in the puters that people buy, then Haiku would be the most popular OS in the world.

                          Maybe... because real people do real things with theirs computer and they don't spend the day running benchmarks ... if a OS can't offer on the client what people need... maybe measuring performances of Apache on the client OS instead of using that time to improve the client overall appeal is a humongus waste of time
                          Yeah very real like listening music and watching porn... only windows can offer that functionality though...

                            Hahaha the casual windows user opinion who always need better hardware for basic operations. 10-20% difference is not a real difference? Maybe if you happen to change your puter every 6 months...

                            Do you need to read or to write at 250 MB/s or more? Just get a couple of SSDs in raid 0. End of story.
                            What's the purpose of getting a couple of SSD in raid 0 if your software delays your hardware so much making it to feel as if you payed 500 bucks to get performance you could find with 200?

                            Computation benchmarks? It's just a CPU bound issue, what could you expect? A 50% difference between Ubuntu and Windows? No way, it might end up to less then 5%... again, it doesn't make any real difference.
                            Are you sure it will be just 5%? I doubt. Isay it will be 30%. Prove me otherwise without benchmarks...

                            Benchmarks are meaningful to compare a new software version to make sure there are no regressions compared to the previous version, doing cross OS benchmarks to figure out who is peeing farthermost is pointless
                            I agree if you use your pc just to paint triangles...

                            I hope you didn't need Phoronix benchmarks to figure out that GPU drivers are more efficient under Windows 7
                            LOL! That's what you still think? Ithought so few days ago... Try to read the articles (the graphs at least) before try to judge Phoronix.

                            I would be interested in evaluating specific softwares on different platform to have a overall result of the application software + the operating system. Example: Photoshop on OS X and Windows 7. Not to determine if OS X is better than Windows 7, just to figure out if Photoshop runs better on one of the two OSs. Very likely it won't and it might be just about the same. And anyway, with different software you might get opposite results, just like different GPUs with different games or different resolutions/details levels.
                            That's wht Phoronix does actually. Testing the same software in different platforms.

                            At the end of the day I need to get the job done, not to go telling that my OS is 3% faster than the competition
                            I have automated my system in such a way that I have a lot of free time actually. You know, no viruses to deal with or no needing to buy software and have to work more to find the money etc etc...

                            So I welcome real user scenario benchmarks of real client software running on client OS... not fake test running server software on a client OS.
                            I have a desktop OS which I use as a server as well. My mate the same...

                                Yup, I agree. That's why we run tests and benchmarks.
