Dave might not run properly (or at all) with some video cards, however you may
try to fix this by modifying the "dave.conf" -file. It is recommended that you
change the following options one at a time until Dave works properly.

teletext_mipmap	off
- Use this if you can't see the main menu or the HUD. Especially for ATI's
  gfx-cards

simple_shaders	on
- If Dave does not run at all, this might fix it

shaders	off
- This usually makes Dave run but it'll disable all effects and make Dave
  look quite bland :(

fbo	off
- if your gpu doesn't support frame buffer objects

vbo	off
- if your gpu doesn't support vertex buffer objects
