Hi guys,

I just read about posix shared memory (ATI video card), and wondering, how could this affect the video performance of my HD4500 card. Should I try to install an official ATI driver from their website, messign up with these things, or should I just stick to the driver from jockey? With the current driver in the Ubuntu repo the Gnome Shell is too slow, but with the open source driver I have no 3D in games

Please share any experience!
