Yes, but note no hardware composition is involved. The composition is done by the 3D GPU like I said. Either in your app if you render that video yourself, or if you supply a swap chain’s back buffer to IMFMediaEngine.TransferVideoFrame met

GDI is only used by legacy apps. It gonna stay there for quite a while for backward compatibility reasons, but modern Windows apps are using better GPU-centric APIs to render their GUI. Specifically, WPF is based on DirectX 9, Direct2D is b

2D games are mostly rendering sprites. GUI renderers do that too for raster images and font glyphs, but the harder part for GUI is vector 2D graphics.

The higher levels of the stack, be it hardware or software, need to make sure that never happens. That’s how GPUs are doing that. Each thread group can use a limited amount of SRAM, programs declare in advance how many bytes they need. Then

Very relevant. Apart from a few minor exceptions, C++ is a superset of C i.e. almost any C code can be compiled as C++ language, and will result in a correct program.

If I would rework that snippet to be in C instead of C++, that code would no longer be my today’s WTF. Also, IMO `std::max` is more readable than the equivalent conditional operator.

Interesting, thanks. BTW, I fixed like that: uint64_t mask = -( missingLanes < 8 ); mask >>= missingLanes * 8; I only care about the AMD64 because the surrounding code uses AVX2 intrinsics, i.e. my new version is hopef

I think the #1 reason for these regulations wasn’t compatibility, it was safety. People die in fires, railway accidents, aviation disasters, and from waterborne infections.

How would you fix the fundamental problem? It’s technically possible to force these two companies to implement a shared API, but hard to do, and “Vulkan API Support Act of 2024” sounds a bit weird, IMO.

Neither Apple nor Microsoft want any usable multiplatform graphics API. For this reason, none of them delivers such a thing. If you want a multiplatform graphics API, you should use a library which implements such API on top of these native
