3 suggestions I have for VKQuake.

[ghost]

1. Add options in the menu for enabling/disabling animation interpolation.
2. Add back the opening demos.
3. Add an option to disable mipmapping on textures. Sometimes this can be very distracting on floor textures.

You can add the first 2 by just putting a few lines in an autoexec but it would be nice to just have them out of the box.
