nish well, i assume it does (but we all know what happens when you assume). in the control panel it has settings for opengl, i guess it does. all i know is, i switched from nvidia geforce 4 and it made a huge difference. i can run games with all the settings maxed @ 1280x1024, full aa and af, and they run great! are you thinking about an upgrade? if so wait, they have two coming out, the 9600 pro and the 9800 pro that is going to include a free copy of halflife 2 (if you're into gaming that is, if not just send the game to me....lol). i will try to find more specifics as to what the modle will be if you would like!
