I just installed Age of Empires and the graphics are mucked up, I tried the demo and it looked fine... advice?

You should try to change the graphics settings from the options menu

Ive been there now first thing . The demo has a fraction of the system req. so double check them, Ram is a BIG 1 if it needs at the min. 256 and thats what u got when u get a larg game going its going to get scrooy with u for lack of .If was the program it probly wouldnt be working at all reinstail just in casegood . Oh and right click ur desk top ,propertys ,settings advanced max ur hardware boost and lower ur pix rating to releve stress on the card good luck :)

could be a corrupted install, could be down to graphics drivers. if you've changed anything since you played the demo change it back (i.e. drivers) but other than that if the garphics in other games at this moment are fine it's just a bad file, try a re install or download a new copy

The Copy you have has a problem. try a different copy of the game
