hi! i have an an intel celeron 2.4ghz with 512 mb ram. i have upgraded my graphics card from geforce4 mx to ATI Radeon 9600 256mb ram. when i play games such as Half-life 2, i can see that the graphics have improved like lighting , shadows etc, but the FPS is still slow and its basically quite the same as it was with the geforce 4 card. how can i improve the FPS rate to get HL2 to run at least with 26 fps. thanks! btw this is how my graphics card looks like: http://www.buyxg.com/images/VC/VC-105-184.jpg all help is greately appreciated!
