You should go to ati website and download their 10.8 mobility driver. My laptop has an Asus Mobility Hd2600 with 10.7 drivers (10.8 will work too) and it runs the game just fine. So you probably just need to install 10.8 (newest) drivers the one your using (8.512) is too old .

In ATI Site.
Downoad Drivers - Notebook Graphics - Mobility Radeon Series - Mobility Radeon HD2xxx series - Your Os.

Btw when uninstalling your old driver do this.
First you go to control panel - add remove programs - Run the ATi uninstall software, then uninstall ATI Driver first, Catalyst Control Center second, then last the ATI Uninstall software itself. After that , download a program called drivercleaner, boot up in safemode and use driver cleaner to erase any traces of ATI old drivers. Reboot back into windows and install the new driver.
