yeah i am talking about performance...i keep the resolution most of the time 640x480 i guess...without using catalyst i get more speed....and when i download the desktop version of catallyst..only the version 9.9 installs the ccc but not the versions after that ..the latest catalyst frivers just installs the install manager and nothing else....they doesnt install the ccc
Well, that seems to be a bit of a problem right there... You state that you have Mobility Radeon HD2400XT... mobility as in mobile--mobile as in a mobile PC--your notebook! You can't install the desktop version of Catalyst. If you would have followed the link I provided in an earlier post, it was to the Mobility Radeon driver download page for the 10.4 version.
If you are running games at 640x480 and are not getting playable framerates (I don't know why you wouldn't) then try adjusting the 3D properties from within Catalyst to "Performance." If you are running the games at the native resolution of the display, 1280x800, then again, adjust the 3D properties from within Catalyst for "Performance," and try adjusting the resolution from within the game from the native display resolution to a lower resolution like 800x600 or 640x480.
I don't know much more to input... If you're having that much trouble using Catalyst, then I'd suggest not to use it because there seems to be a "somewhat" generic ATi, Microsoft supplied, display driver minus Catalyst Control Center. But, I'll ask again: What performance are you seeing and what are you expecting? Do you have a application to measure framerates or are the games just so stuttering that you can obviously see that something's wrong?
Lastly, the only other option for you would be to go to Acer's website and download the driver for your specific model. I've checked and the driver name is VGA_ATI_8.477_Vistax86.zip--It may work for you in compatibility mode... you'll have to try and see. (There are no Acer drivers in the drop down menu selection for Window 7 Pro 32-bit)
Good Luck!
EDIT: Important: You are uninstalling the previous driver package before attempting to install the new packages you've tried, right?
