I just beaten carmageddon 1 and now wanted to play the splat pack part of the game, i am playing it all in software mode since the integrated chip nividia geforce 6150 256mb isn't up to the minimum requirements but the game still works fine except i don't know why only in splat pack it plays only in the middle of the screen in fullscreen while the huds are out of it.
Here a screenshot if anybody knows what i can do to change some setting that it would be full screen properly like in carmageddon 1:

Also am playing it on windows xp sp3

Hey you were right.
Thanks for the suggestion didn't know why the game worked like that but the + and - certainly did the trick.

Glad to be of help.
