Gauntlet actually works well on ATI. its the surfaces on turok and smashing drive that are wonky.My bad. In that case I have no answer yet. ATI cards are known to show all kinds of crazy stuff, and Dxbx is not as stable as I want it to be either. This will improve, I'm sure, but these things take time.
I took these screenshots using DXBX's f12 button. The bmp format is too biglolwut, it says PNG, but the images themselves are JPG. Bill, you realize that just renaming a JPG to a PNG doesn't make it a PNG, right?
And FYI, NEVER resave a JPG as a PNG (unless you're doing image editing work).
