FSAA not working on my 9700 Pro

[Goi]

Hi guys,
Just got a sweet Radeon 9700 Pro for my new system, and also downloaded/installed the latest Catalyst 2.5 drivers, but I'm not getting FSAA when playing Q3A. In the Display Settings->Advanced->OpenGL settings I've played around with different FSAA and AF settings, but none of them seem to have any effect on Quake 3. Its the only 3D game I have at the moment so I've no other way to test. Does anyone know what's wrong?

Wow...that's weird. I run Q3A with 16xAF/4xAA and I can clearly see the difference in AA. Can you post a screenie or two? What resolution/settings are you running? I have heard a few cases that 6xAA will not run at 1600x1200 for certain games - maybe that is the case for Q3A as well. Outside of that, I don't think i've had a problem or heard of such a problem. I hope this helped somewhat.

make sure you're running in 32 bit color - there's no support for fsaa for the radeon 9700 in 16 bit color mode. there's a long thread on rage3d petitioning ati to add it, so maybe in the future it'll be supported.

OK, here's a screenshot of my ATI Display Control Panel, in particular the OpenGL settings tab.
Here and here are 2 screenies of Q3DM7. In the first screenshot it is more apparent that no FSAA is being applied.

32bit color is being selected, not 16bit.

Any ideas?

OK, I think there's some sort of problem with 32bit color. I've enabled it in game(both game and texture color depth) to 32bit, but when I click on "DRIVER INFO" it shows me that Z buffer is 24bit, stencil is 8bit and color depth is only 16bit. Why's that so? Can I force it to 32bit color?

Those are my settings exactly, those screenies are definately not FSAA, and my driver info shows the color depth as 32 bit. I think thats your trouble, but I'm not sure...maybe in the Q3config file?

OK, I found the problem. Turns out a remnamt of my old autoexec.cfg, with the command "seta displayrefresh 160" caused the display to lock at 16bit. I guess somehow at that refresh rate only 16 bit color was supported. Turns out you're right...thanks
