Comment désactiver les avertissements de performances Aero de Windows 7?

Sometimes this dialog box will pop up (see screenshot above). Every time it appears I select “Keep the current color scheme, and don’t show this message again”. Windows then reminds me again - either the next day or after reboot, or sometimes another 5 minutes later

Do you want to change the color scheme to improve performance?

Windows has detected your computer’s performance is slow. This could be because there are not enough resources to run the Windows Aero color scheme. To improve performance, try changing the color scheme to Windows 7 Basic. Any change you make will be in effect until the next time you log on to Windows

• Change the color scheme to Windows 7 Basic
• Keep the current color scheme, but ask me again if my computer continues to perform slowly
• Keep the current color scheme, and don’t show this message again

Is there some reason why Windows is ignoring/forgetting my attempts to suppress the dialog? I’d love to never ever see it again, it’s annoying, and it alt-tabs me out of fullscreen applications.

If it matters, I’m running Windows 7 x64 Professional. I believe the dialog appears because I’m forcing Vsync and Triple Buffering for DirectX applications.

Assuming you realize this message is informing you your system is low on resources and is asking you to disable Aero so it can keep performing at optimum speed,

1. Go to the Start Menu and type Action Center on the Search box
2. Start it (it should be the top entry, under the “Control Panel” group)

3. On the left sidebar, click

   Change Action Center settings

4. Décochez la

   case à cocher, sous «Messages de maintenance».

5. Clique le

   Ok

   bouton et vous avez terminé.

Voici une capture d'écran de l'écran de configuration:



• Vous pouvez essayer de conserver ce paramètre tel quel et basculer en mode Bureau simple avant de lancer les applications qui déclenchent généralement cette notification du Centre de maintenance. Ou,

  Disable desktop composition

  . Cela désactivera leGestionnaire de fenêtres de bureau service pendant l'exécution de cette application, ce qui augmentera la mémoire système et vidéo et évitera certaines incompatibilités d'applications. Une cause probable du message Action Center si vous disposez de suffisamment de mémoire système et vidéo mais que vous recevez toujours ce message avec certains jeux ou applications plein écran.

Oliver Salzburg, un autre contributeur, s'intéresse à la solution Disable Desktop Composition qu'un nain met en évidence à la fin. Il écrit:

I’m constantly in a similar situation even though I never get that exact same message, and have done a bit of testing around.

To my understanding, the core resource that is under stress here, is the GPU memory. But this doesn’t necessarily indicate that you’re running out of this resource in general. It might just mean the Desktop Window Manager has detected that you’re running so low that one specific feature of this service could be disabled to free up more memory.

To test this, I started opening up GPU memory intensive applications:



I had to push a bit further and start a couple more Visual Studio instances…







Now, when I’m already at a critical level, and I start an application that uses excessive amounts of GPU memory in fullscreen, I can even go beyond this critical limit. Here’s the result after running Black Mesa for a while on 2560×1440 at max details:



So, two things can be deducted from this. While going over the 75% mark on the desktop can force Windows to disable desktop composition, when reaching the same limit in a fullscreen application (and, optionally exiting that application) desktop composition is not disabled. The second thing is, while you’re in your game, you can get the idea “Hey, I have enough resources to run this game, why don’t I have enough resources for the desktop?”. The reason is, both require memory at the same time.

Windows might only be able to tell you about the memory situation after you exited the game. So, when I start another Visual Studio after exiting Black Mesa…



Get more GPU memory

Sweet and simple.

Disable Desktop Composition (per process)

As was already suggested, you can disable desktop composition for a single executable. This has the effect that desktop composition is temporarily disabled while the executable is being executed. This drastically reduced the overall memory consumption while the application is executed in my tests:



Disable Desktop Composition (globally)

I wouldn’t consider this a solution as desktop composition is usually desired. But this is where to disable it:



I just want to get rid of the annoying message!

Just because you remove the warning “ Your battery is almost empty! You can only talk for 10 more minutes! ” does not mean you can talk for longer than 10 minutes. In fact, your phone will most likely simply shut off and that’s it. Now how’s that for an improvement?

I never assumed the message can be turned off and I don’t see how that could be considered a benefit.

You might think you know better, but you don’t. If the system is telling you it’s running out of resources, it is.

But it isn’t! I know!

Ok, let’s assume Windows is just not smart enough to detect the special situation you’re in and the warning message is simply an annoying inconvenience. What now?

The thing is, me personally, I’m also affected by this and it’s annoying the hell out of me. Because I don’t even get that warning message. Windows simply switches my color profile and that’s it. And I like that actually.

When it happens I usually quickly run a script that calls

net stop uxsms & net start uxsms

Cela redémarre le gestionnaire de fenêtres du bureau et me ramène à mon bureau composé (ce qui libère beaucoup de ressources, yay).

Sachant cela, vous pouvez également créer vous-même un environnement de jeu spécial dans lequel vous arrêtez le service avant de commencer le jeu pour combattre tout ce comportement. Cependant, cela entraînera un comportement identique en désactivant la composition du bureau pour un seul exécutable via les propriétés du fichier.
