I know WPF is more complex an flexible so could be thought to do more calculations. But since the rendering is done on the GPU, wouldn’t it be faster than Winforms for the same application (functionally and visually)?

I mean when you are not running any games or heavy 3d rendering, the GPU isn’t doing heavy work, right? Whereas the CPU is always busy.

Is this a valid assumption or is the GPU utilization of WPF a very minor operation in its pipeline?

EDIT: The application that I am interested is a 3d modeling and animation software, where you have 3d viewports to navigate and edit the scene, and objects inside the scene. But I want to use WPF because of its modern architecture, and it’s from scratch.

EDIT2: Also for my purposes I will use DirectX hands down for the app itself because of the high end requirements of the software. As for people using lower end or computers without a dedicated GPU, that’s OK since they aren’t not in my primary customer area. Just like other high end 3d software for film and games, it will be understandable to require a powerful computer to fully benefit from the application.

    Provided the machine has a GPU, you’ll get better rendering performance in WPF.

    We have a large desktop application that we wrote in WinForms, and are now porting to WPF. We’ve witnessed much better rendering performance, particularly when resizing windows or redrawing controls.

    We’ve also found that WPF “controls” are more lightweight than WinForm controls. If I recall right, WPF controls do not necessarily require an operating system handle, and don’t register for Windows window messages via WndProc, at least not independently.

    For your case, since you’re building a 3d modeling app, which kind of assumes some 3d hardware on the machine, you should absolutely use WPF over WinForms.
