i can max out COD4 at 1920x1200 on all settings. if youve played the demo and thought that you can get higher details,textures etc in the retial version higher than normal youre worng. you only have the option of low or normal. gret game tho. really chuffed that they made more like the first one. single player is amazing! bit short but very very intense!! multi player is realy good they have a rank system similar to BF2 and you can open up options by doing challenges for extra attachments to your guns.
really chuffed by it i was disappointed by COD2 multi as COD UO was amazing as well. i would give COD4 9.5. great game well worth the money
