My previous card was an Nvidia, but it was 8600 or something and burned out, so it had to go.
I've been considering getting a cheap - but more recent - Nvidia to have both options, and also because my old XP actually has no video card at all.
Anyway, the grass. I've noticed a few errors remain on Dxun, and Dantooine's grass has some of those mapping issues I mentioned, so I'm going to take a look at it again. I have compiled a bunch of minor fixes, so I'll release the updated grass with that once everything's ready.
