Window size issue - different sizes on different PCs

Irolan

Hello,

I'm having the weirdest issue concerning window sizes. I tested my current executable on 3 different PCs. All of those PCs have screens with a resolution of 1920x1080. The Window-settings in the display category of the project settings are Width: 1920 Height: 1080 Resizeable: on Borderless: off Fullscreen: on Always On Top: off Test Width: 1600 Test Height: 900

I exported without debug.

On my primary PC it works fine - full screen at 1920x1080. However, on the second PC it looks like it is running in a borderless window at 1600x900. Now on the 3rd PC it gets really strange, because there it runs as a borderless window at 800x480. I haven't the slightest idea where it gets that small resolution from, it is not set anywhere. The second PC has never run a Godot game before, so there should be no previous config or something.

Does anyone have an idea what is going on?

Try setting HiDPI to on in project settings, this fixes issues with Windows scaling. Also test width and height are not really supposed to ship a game with, they are for testing. You can use stretch mode or scale the viewport to get the correct resolution. You can do this in GDScript.

OS.set_window_size(Vector2(1600, 900))

I tested it with and without the test resolution, didn't change anything. Just tried the command, that didn't do anything. Neither did toggling HiDPI.

Update: I turned off the fullscreen option and in the first scene set

func _init():
  OS.window_fullscreen = true
That works. However, I already know it's going to be an issue when the player uses a screen that doesn't have a 1920x1080 resolution and when I want to support different resolutions.

For different screen sizes, in the project settings you could see if setting the Mode property under stretch to 2D and the aspect to Expand or Keep helps. Then if a window is smaller or larger, it will resize the content to best try and fit it with the width and height project settings.

Godot always runs at native resolution. The resolution you set in the options is just for the renderer and how it scales to the screen. In fact, very few modern games support exclusive fullscreen mode anymore, most vendors recommend you don't use it (after DX12 and Vulkan game out). In any case, it's not even supported in Godot. But you have to adjust the Window Stretch options in the Project Settings. It will depend on your game which settings work best.

Yes, I tried with different sizes and modes. Somehow I can't get Godot do do this properly. It either gets pixelated, or it looks like someone tried to resize an image with MS Paint. Maybe that's because I imported all the graphics without filter, but if I leave filter on, everything gets blurry.

I wasn't aware that most modern games no longer have exclusive fullscreen. The ones I played recently did (or at least what I'd consider exclusive fullscreen). Also, if it's not supported, why is the option still there?

It turns out, setting the window to borderless works, too, though. And it doesn't cause weird scaling. It's fine for this game as it has no mouse control, so no danger of accidentally clicking outside the window. However, now I noticed another thing. On my laptop Windows is set to display text and UI elements at 125%. This also seems to cause the game to display at 125% resolution, meaning parts of the game window are outside of the screen. None of the settings seem to change that. Can I remedy this or do I need to tell the players to set their screen's scale to 100% before playing?

HiDPI setting should fix that. It works for me.

For future, see https://github.com/godotengine/godot-proposals/issues/3681 which proposes enabling Allow Hidpi by default in Godot4.0 and later.

Thank you, that put me on the right track. Activating HiDPI is half of the necessary steps - it fixes it visually, but the application still thinks it's a different size. The executable also needs to be set to overwrite high DPI scaling. If anyone has the same issue and doesn't know how to do that: Right-click the game executable, select Properties, go to the Compatibility tab, click "change high DPI settings", check "override high DPI scaling behaviour" and set it to "application". Do the same thing to your Godot.exe, then it will also work with the play test.

What version of Windows are you on? I've never had to do those steps.

Enabling Allow Hidpi in the project settings will enable DPI awareness when the project starts, but you need to export the project again for it to have an effect on the exported project.

Yes, I did that. But I still needed to override the high definition scaling behaviour in the exe's settings. I don't know why. But at least I can work with that.
