Performance question in Win2D on WinUI 3 (win32)

[dimohy]

I want to use Win2D in WinUI 3 (win32).

The 'Gallery of Win2D examples' from the Microsoft Store shows very beautiful behavior.

So, using the source code of 'Win2D Example Gallery', I understand Win2D and reconfigure it as a WinUI 3 (win32) project.

However, the performance of 'Invalidate()' in 'CanvasControl' is significantly different from Win2D in UWP.

I want the performance of Win2D on UWP. I'm not at the level to look into the source code of WinUI or Win2D, so I desperately need your answer.

Hi dimohy, which examples are you experiencing the poor performance on?

CanvasAnimatedControl is not yet supported by WinUI 3, so it happens in the example where CanvasControl is used. From what I have confirmed, it seems that it is because of the delay between drawing again after executing the canvas.Invalidate() method rather than drawing performance. What I suspect is that the fps seems to be locked.
