Maybe I'm a *****, but I installed Onimusha 3 on my PC, but it stays in windowed mode! I can't get it to go full-screen, even though in the options menu, it clearly says "full-screen". The demo did the same thing. I'm running an Nvidia 7800GS.

I am having same problem. And worst, after I downloaded a patch, the windowed mode became smaller.

Hey guys, not sure if this will help.. but from the Ubisoft PC FAQ:

"Browse to the game folder (C:\Program Files\CAPCOM\ONIMUSHA3 PC) and try launching the game by clicking on the "Onimushalauncher.exe". This should load the game in full screen. You can then change the game shortcuts to point to this executable instead."
