Stride and WPF

[jhimes144]

Hello,

I'm exploring using WPF as UI for my game. I was able to get an app running with WPF and the game rendered inside. However, the game is being rendered on top of the UI. I've been trying to scour the source code to see how the Stride Editor does it, because its able to draw context menus on top of the game view. Any ideas? Thanks.

EDIT:

After messing around, I was able to get wpf rendered on top of the game by making a borderless wpf window that allowed transparency, and using win32 functions to sync its position with the game. However, this requires the game to run in windowed mode (borderless and fullscreen, but IsFullscreen is off), and in window mode the game's performance suffers a lot from excessive screen tearing, I've yet to find how to fix this.

For your frame rate issue can you try adding this within your gamecontext?

WindowMinimumUpdateRate.MinimumElapsedTime = TimeSpan.FromMilliseconds(1000f / 144);
MinimizedMinimumUpdateRate.MinimumElapsedTime = TimeSpan.FromMilliseconds(1000f / 144);

It may be a weird issue where the window thinks its minimized or out of focus so it uses the default fps limit.

If you need a spot to put this code you can override the Game class like below:

public class CustomGame : Game
{
	protected override void BeginRun()
	{
		base.BeginRun();
                // force 144FPS when in focus
		WindowMinimumUpdateRate.MinimumElapsedTime = TimeSpan.FromMilliseconds(1000f / 144f);
                // force 144FPS when out of focus
		MinimizedMinimumUpdateRate.MinimumElapsedTime = TimeSpan.FromMilliseconds(1000f / 144f);
	}
}

and then in you startup where you run game.Run() use the CustomGame class instead of the Game class.

Thanks for the help, unfortunately I'm still getting screen tearing. (This is with the fps template btw)

interesting last thing I know about is https://forums.stride3d.net/t/how-to-disable-frame-rate-throttle-and-vsync/2094 where it might be a vsync issue? if you try changing the GraphicsDevice.Presenter.PresentInterval to something else maybe it will help.

If this doesnt help would you be able to share what you have done so far with the window renderer? Maybe I or someone more knowledgable than me can play around with the code to see if something comes up.

I came a across that forum earlier and tried those options, thanks for the help. I just opened this issue #2216
