When it comes to graphics, Windows is now far ahead of macOS. It's simple economics: the GPU manufacturers work with Microsoft for DirectX support due to userbase (especially the game playing userbase, which is where all the profit is). Apple, on the other hand, struggles to keep up with Metal on the same GPUs, unwilling to invest the money to keep up. DXGI, for example, is an extremely powerful and well-supported API, as compared to IOSurface which is like stumbling around in a dark cave.

(On mobile, things are different, but even here PowerVR is increasingly looking beleaguered compared to ARM and Qualcomm's offerings.)
