Im having problems with all the typing in JKII. In the main menu the letters are so fuzzy and distorted that you cannot even begin to figure out what they are. I dont know if it is my video card or the game. But no problems with the video while playing. oh ya i have a voodo 5 5500 64mb card.
When you get in-game, bring the console down and type:
The game will reload the map and such and the writing *should* reappear. You might have to do this everytime the map changes ;)
I had this same problem with my Voodoo 3, but now I have a new computer so it doesn't happen anymore. This seems to be a problem with Voodoo btw, other people mentioned the same problems. So far the only solution was the vid_restart.. I know it's annoying to do, but better than nothing :)
