Only a few games have resizable windows when running in full screen mode. All others have a finite fixed set of allowed resolutions. But why? I see some reasons, but none of them seems to be that important to me that would justify such a user-unfriendly feature.
Let's use Dark Souls II, because it's the first I can think of. The allowed resolutions are:
What is the reason to not allow the resolutions
800x451, 800x452, ..., 801x450, 801x451, ...? What it I think can't be:
- The UI. If we keep minimum and maximum window sizes as limitations, the only issue I can see here is with settings with a weird aspect ratio (1920x450, 800x1080). Otherwise, there shouldn't be any problems with free scaling between the resolutions.
- Camera, Viewport. Same as above.
