Except you are clearly saying it cannot ;-)
Solution #4: Throw money at your PC. Get an nVidia 5900XT or 6800GT or
something, and use OpenGL.
I run gpl at 1600x1200 with 8xAniso, 100% detail & so on & get about
32fps at the back of a full gplea grid (about 30 at Monaco with the
rocks update), and 36 fps everywhere else. No transparent cars, lovely.
Don't really need AA at 1600x1200 but the card has the power to use it
online & hotlapping so I do. I'm rarely at the back of a full grid of AI
but I often watch server replays with full grids.
Problem solved ;-)
