I installed Call of Duty 2 game and finished successfully without any errors in less than 10 minutes from its files in my folder (not in CD-ROM)!
Then I started the game, the game was running smoothly until I clicked New Game and the game was loading. A few seconds later it blurred like when your windows hang up and you drag it to elsewhere and it has more fake windows until you terminate its process .
So, If you know the way to get rid out of this problems, please help me!
PS. I have using Ubuntu 10.04 with ATI Radeon HD 4300/4500 Series graphic card.
