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.

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.

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.
