[Bug-gnubg] CPU load versus GPU for graphics???

[Rich Heimlich]

I just upgraded to an Intel Core 2 Quad Extreme processor and an EVGA 
Nvidia 8800 GTS.

GNUB really looks great with it. However, I noticed something that I 
hadn't expected. While playing the game the CPU fan cyles up and down 
continuously suggesting that it's working hard at various points.

I started watching it while playing and noticed the overhead running as 
high as 30% usage during typical moves. That seemed excessive to me. I 
then decided to see what would happen if I changed my board from the 3D 
"Oak/Maple" board to a 2D board. The CPU load dropped down to 2% max.

Why isn't GNUB using the GPU more for the graphics? It seems obvious 
that the game could likely run much snappier if all 3D functions (or 
nearly all) were offloaded to the GPU. I would have to think that these 
cards can handle anything a backgammon game wants to throw at it.
