Chimera does not use CUDA. It only uses the GPU for graphics (e.g.
lighting with GLSL fragment shaders). Frames rendered per second is
usually limited by GPU speed in Chimera, but setting up scenes (loading
molecular models, computing surfaces, ...) is limited by CPU speed.

> I have a customer and they are using Chimera:
>     * Customer: Institute of Biophysics of China
>     * Platform: Dell 5500 workstation, Windows VISTA 64bit OS, FX4800
>       , Quadro driver version : 259.81,
>     * Application: UCSF Chimera 1.5 for protein molecule analysis
>     * Status: Chimera for 64bit OS , the graphic 3D performance would
>       be 5 times fast than Chimera for 32bit OS in VISTA64
>     * Need to check: Whether Chimera using CUDA/GPU accelerating function
