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.
