Supported Graphics Cards
GPU1 client: ATI x1600, x1800, and x1900 class (discountinued June 6, 2008)
GPU2 client: ATI HD2xxx, HD3xxx class, HD4xxx
Announcements have been made that support for nVidia GPUs is currently under development.
[edit]
Will earlier ATI cards such as the 9600PRO ever be supported?
No!
The short technical answer is that those boards do not support looping constructs and are also 24-bit precision which is a problem for us. The X1K boards were the first to support 32-bit precision and branching/looping on the ATI/AMD side of the world. ---mhouston [1]

Known Issues
- If Windows enters the "fast user switching" screen the GPU core will quit. Solution for now is to turn off the screensaver going to login screen.
- Doing a 3-finger salute [ctrl][alt][del] to bring up the task manager will also cause the GPU to exit. Solution: right-click on the task bar then click "Task Manager"
Note: The GPU2 clients based on CAL and CUDA have resolved many of this DX9 context based errors.
