[CentOS] 3D acceleration not running

Hi,
 
I installed a :
 
DELL T3400 
graphic card Nvidia Quadro FX 3700 
graphic drivers NVIDIA-Linux-x86_64-180.44-pkg2.run
CentOS 5.3
Monitor DELL 2408WFP
 
When I started glxgears , it's slow. 
I'm using vmplayer 2.5.1, when I start dxdiag direct 3D is disabled.
 
3D acceleration is not running.
 
Any help will be appreciated ?
Best regards.
