I work in AAA. I'm talking lower level things like picking which "type" of GPU memory to allocate, access to specific registers in shaders, etc. PC didn't have real async compute capabilities until DX12, for example.

On the CPU side yeah it's 100% just a normal computer but nothing will be interrupting your threads. I think Windows 10 tries to do in it's new game mode too.

Sorry for assuming the link was the PS5 one. I have a UDN account and their login setup sometimes just dumps me to their homepage, so I made the assumption that it was the same video that I had seen everywhere else.

Indeed it didn't, and DX12 is extremely old tech. Consoles don't have async compute right now. (Edit: apart from the PS3).

AMD GCN absolutely supports async compute[1]. Radeon cards for years would only make use of the ACEs in pure compute contexts, as OpenGL and DX11 had no concept of a secondary command queue and could not make use of them. This is a big part of the reason why Vulkan/DX12 require so much boilerplate to get a triangle rendered.

The PS3's SPU definitely counts as async compute especially with how it was used later in the console lifecycle[2] once people had time to familiarize themselves with it.

However, in the current gen consoles, you don't have to deal with a different ISA, command queuing, and shared memory between the GPU and CELL processor. You are only writing HLSL/GLSL/PSSL and setting up an aggressive amount of fencing to transition resources between readable and writable states within the GPU.
