No, I don't mean that the OS allows fullscreen with the resolution of the game.
For example the game is 16:9, my desktop is 16:10. The game does NOT fit on my desktop, the game will force a resolution change.
The hardware is compatible, the game runs smoothly, but in the process, it messes up my desktop.
For this reason, I prefer that the game is launched in windowed mode and allows me to access the configuration parameters before going to fullscreen mode.
About "skyrim", melee combat, 3th person. Aim with the bow, first person. That's how I play it.
