smuggly: OK I have the mod installed and when I start the tutorial it gives a small screen inside a template area. but it keeps the game basically in a window. is this the best way to play the mod or should I be getting it in fullscreen? Thanks
Antaniserse: Make sure to select one of the "(stretchable)" video options from the 'Mode' combo box
Also keep in mind that the lower combo box, labeled "Source size" does not necessarly require you to put your monitor resolution, but rather the internal rendering resolution... the game will still render at your native monitor resolution, but the graphic will be scaled higher or lower.
This is often useful becaus at very high res, the text becomes hard to read, and the UI too small; for instance i like to use "source size 1216x760" on my monitor, which gives a good balance between extra screen space and still good readability... see here for details:
