…window resolution. Desktop Fullscreen: It was previously possible to run ironwail in desktop fullscreen mode, but only by manually setting a cvar. This change adds the ability to pick this display mode within the video settings menu. Decoupling Aspect Ratio: Previously in ironwail the window/fullscreen size always dictates the aspect ratio tha the game is renderred in. This is fine for windowed and exclusive fullscreen where you can set the specific resolution you want, however with desktop fullscreen, the window must be the same size that your operating system is outputting. Decoupling the aspect ratio allows the user specify a specific maximum aspect ratio to use in this circumstance. For example 4:3 on a standard 16:9 display, or 16:9 on an ultrawide display. The new vid_maxaspect cvar default to 0, which means auto (match window/fullscreen resolution).
Under some configurations where GL_NeedsSceneEffects and GL_NeedsPostprocess return different values the viewport offset was not configured correctly. This change addresses this issue.

I realize now that the desktop fullscreen feature may not be as important as I originally thought for these reasons:
There are still advantages of the implementation in this pull request though:
If it is preferable to remove the desktop fullscreen part of this pull request and just keep the aspect ratio changes, I can do that. Controlling aspect ratio independently of fullscreen resolution is desirable because on ultrawide monitors the UI stretches out to the edges and becomes hard to see. You can of course use an exclusive fullscreen mode with a specific resolution at the aspect ratio you desire, but this comes a lot of problems like slow alt+tabbing and possibly messing up other application window positions and sizes in Windows. |
