I have Acer 4745G with ATI HD 5650 1GB VRAM. After I installed the COD Black Ops trough Wine Playonlinux and successfully installed, and I play the game and then appear message "Shader Model 3.0 not available".
I have installed ATI driver 11.8 when I trying this game. And then I'm trying to install the driver from menu "System >> Administration >> Additional Driver, it doesn't work. I cannot log in, in the screen appear only the text for log in.
And then I uninstall it trough recovery mode. And then I download ATI driver 11.11 from official ATI/AMD website, and then I restart my computer and my screen appearing only text again. I'm using Ubuntu (Ultimate Edition) 11.04. How to overcome this problem?
