To be honest, I’m not even sure whether this behavior is caused by some bug in the game’s engine or by this uncommon graphic card setup. Nonetheless, after some hours thinking and testing, I found a way to make it work. I’ve searched all over the internet after a fix for this behavior, but didn’t find anything. In order to get better effects and fluid movements, we normally set the resolution lower than the native resolution (something like 1366×768), which normally would work perfectly but this graphic card setup causes the game screen to be smaller than the screen area, involved by a thick black frame.

I’ve found that this setup can cause some strange behaviors when trying to play Assassin’s Creed IV – Black Flag and probably other games too, because if forces the resolution to be set at the native LCD resolution, normally 1920×1080 pixels, which is a very high resolution for any graphic card to handle at 30 fps. I have a VAIO laptop that has two integrated graphic cards: one from Intel, for daily/common use, and another one from NVidia for heavy 3D processing.
