Window and Display Settings

Pass GameWindowOptions to the Game base constructor to choose startup settings:

public sealed class MyGame(IServiceProvider services) : Game(services, new GameWindowOptions
{
    Title = "My Game",
    Size = new Vector2(1280, 720),
    Mode = GameWindowMode.Windowed,
    Resizable = true,
    VSync = true,
    MaximumDrawRate = 120,
    MaximumUpdateRate = 120,
    ShowFramerateInTitle = false
})
{
    protected override void Cleanup() { }
}

The original Game(IServiceProvider, maxDrawRate, maxUpdateRate) constructor remains available.

Game exposes the settings commonly used by an options screen:

Game.Viewport = new Vector2(1920, 1080);
Game.VSync = true;
Game.MaximumDrawRate = 144;
Game.MaximumUpdateRate = 120;
Game.ShowFramerateInTitle = false;
Game.WindowMode = GameWindowMode.BorderlessFullscreen;

The available modes are Windowed, BorderlessFullscreen, and Fullscreen. Switching away from windowed mode remembers the window's size and position and restores both when returning. Borderless fullscreen covers the window's current monitor.

Rates and viewport dimensions must be finite and greater than zero. VSync and the draw-rate limit are both forwarded to Silk.NET; the platform window backend determines their exact scheduling behavior.
