getting graphics card to be used instead of integrated graphics
I recently installed FC3 and have a Compaq AMD Athlon comp bought off the shelf and so it came with integrated graphics. However, I have a GeForce FX5200 and I installed the drivers fine as far as I can tell because 1) dual monitors are working fine, and 2)the nvidia splash screen comes up fine at boot. All good, except last night when I played my first game on the setup (America's Army 2.2), I noticed it was extremely and unnecessarily laggy. I told this to my friend who knows a lot more about Linux than I do and he is helping me "move in" to my new system since we have the same distro. Anyway, he told me to do glxgears. It shows in the upper 900s of FPS, which apparently is really crappy and I should be getting like at least 5000 or so. I don't really know reasonable FPS ranges myself, but anyway, it's obvious to me that my graphics card is not being used and he said my graphics driver might be defaulting to the integrated graphics, which makes perfect sense to me.
Any ideas on what to do? Just tell me and I'll try it (or if you need more info). I'm eager to play a number of games and this is frustrating me to not be able to.
Thanks in advance,
