my old graphics card died on me, so I decided to upgrade to a nVidia GeForce GTX 780, which runs like a charm.
I can play games such as Skyrim, Theif and Far Cry 3 on max settings, with no problems.
After I installed my new card, I did a re-install of windows pn my PC. Then I had to re-download SOW Gettysburg.
The game installed fine, but when I open the game, it only takes up the center of my screen:

The game played just fine before the old card died on me. The "Fullscreen" option is tagged on, and I have tried to play around with different in-game resolutions, but it dosen't help.
I also used to play the good old game "Heroes of Might and Magic 3", which also ran perfectly fine before, but now suffers from the same issue:

Any ideas?
