I´ve always downloaded drivers from nVidia.com, no exception this time - made sure I had the latest drivers for my Geforce 330 before installing CoD.
The game was still unplayable on my i5 3,2 GHz with 6 GB RAM, 1 Gb 330.
A couple of days ago I was just fooling around, and for some reason I though why not chech for updates via Device Manager in Control Panel. Not sure where Windows finds these updates, but it did find something, and obviously not from nvidia.com. Downloaded a rather big update, and now I can actually - to a certain degree - play the game at medium settings.
I´ve also noticed increased FPS in windowed mode, but the game crashes to desktop every single time I try
(I´ll do some more testing when I get home tomorrow, perhaps setting the windowed resolution to the same as my screen will do the trick)
Anyway, just an idea for those of you with geforce cards, perhaps the nvidia-drivers aren´t optimal for this game for some reason.
Cheers
