Slow Rendering Maximized Window On Windows

[FMXExpress]

I have this project ( https://www.fmxexpress.com/deep-space-rocks-runtime-customizable-mobile-arcade-game-for-delphi-10-2-tokyo/ ) which uses a game loop. It works fast in the standard FMX. The normal screen size (not maximized) runs fast and the maximized version runs fast (this is all on Windows). When I add Skia4Delphi 5.0.0 to the project and run it in the normal screen size (not maximized) it also runs fast. When I maximize the window of the Skia4Delphi 5.0.0 enabled version then it runs slow.

So something is different with the way the Skia4Delphi version effects the game loop vs. standard FMX rendering under Windows. On the larger render area it effects the performance.

I remember an issue like this in v5 and fixed in v6 beta. Could you test using the latest version? v6.0.0-beta4.

I tested the projects and I confirm the slow performance with Skia using the default Windows render (raster CPU), but the normal performance using the Skia OpenGL (GPU) or Skia Vulkan (GPU). I will keep this opened for now because maybe we could change the default backend of Skia for Windows.

You can also test it adding to the dpr:

  ...
begin
  GlobalUseSkia := True;
  GlobalUseVulkan := True;
  GlobalUseSkiaRasterWhenAvailable := False;
  ...

For windows, it looks like the mainform property 'Quality' to HighPerformance/HighQuality has inpact also. Is that something that you also notice?
