Ok. I know that this probably doesen't deerve to be here, BUT I really need help with this! For some weird reason, whenever I turn on my anti aliasing, in some games (most noticably Homeworld) the menus and 2D images get totally messed up. Theres smears, ghosting, weird looking letters, its just funky. Even the mouse leaves  visual artifacts in its wake. This all happens in OpenGL. When I turn it off, all is fine. But I wanna play the games in AA since I got a GF3! It even does it for the movies in FS2! Its weird! HEEELP!

On Voodoo cards you can asign a key (like F12 etc.) to toggle FSAA on and off. This only affects the visual aspect, the performance hit is still there, but its useful to make blurred text readable. I dont know if GF3 has this option, but look around in the display settings.

For me the movies in Freespace is not affected by FSAA, but I know Nvidia uses another method of FSAA than 3dfx, so that may explain it.

Yip i got this problem with my GF3, i have to knock off Anti aliasing for Empire Earth cos i get the same prob but i then have to put it back on for FS2 so i don't get the "Jaggies" problem, i have also noticed that it only does this weird effect with Homeworld, empire earth and any other 3d stragey game unlike AVP2 and wolfenstien Anti aliasing is works brillantly on them. so maybe its something to do with the GF3s and i c that GF4s are rumoured to be released in feb.

well, I know from trying to get Freespace working with Elsa's 3D glasses that the FS menus and HUD items are positioned along the Z-Buffer, not just in front. (Z-buffer is the depth of an object from the screen). So it may be that the GF3 messes up when it tries to anti-alias a flat 2d object, like a movie or HUD text, like it were 3d.

I was under the impression that the GeForce implementation of FSAA occurred in memory, after everything had be flattened down to an individual bitmap and just before the actual BLT to framebuffer??
