- CyberRabbi 6y ago> Rendering method > In order to maintain compatibility, GDI performs a large part of its rendering to aperture memory using the CPU. In contrast, Direct2D translates its APIs calls into Direct3D primitives and drawing operations. The result is then rendered on the GPU. Some of GDI?s rendering is performed on the GPU when the aperture memory is copied to the video memory surface representing the GDI window. I can’t say for certain but I think the main point being communicated here is that Direct2D uses 3D driver interfaces to get its pixels on the screen. Not necessarily that it renders the image using the GPU. I could be wrong.
