I've got the full version of the PC game, and even though in Options it lets me choose '1280x1024x32' (the resolution I want to play with), when ingame, the resolution is only 1024x768x32.

Is anyone else experiencing this problem or knows how to fix it?

Yes - I think this might be happening to me too. No idea what might be causing it or what the solution is.

Last year, when I had a Radeon 7500 for Fifa 2004 it only offered me a selection of the lower res options and I needed a patch to fix it. Then I got a 9200 and it was OK.

Maybe this is a similar thing - only the game is showing us resolutions that can't be used rather than not showin them in the options menu.

I'll experiment...

For me too..

...Still no joy with this yet.....
