Ok so I've had this game for years.. but for the life of me I can't figure out why it looks like total rubbish when I run it.. I don't even get proper tank running gear, all the textures and geometry looks like DOS era pre-3d card stuff and it looks absolutely NOTHING like the screenshots (see the attached screenshot). I've run the setup and everything is set to max, and screen res is 1920x1080. One thing I will note is my usable RAM and video RAM are negative, which I assume is due to some kind of integer overflow

So I know there are mods.. but I'd like to get this working vanilla before I do that. Any help would be appreciated
