high level assembly language
No such monster except for HLA which I don't use.

Assembly can be used for extremely fast copy operations - basically bitblt's from one surface to another. Multi-texturing can be done this way, and using MMX, can also be alpha blended as well if, and only if there are no hardware resources available to do this. Often times the resources are quite limited so this happens more than you think.

But coding an entire DirectX or OpenGL game in assembly, well....................let's just say you and I wouldn't be playing any games developed in this century on our systems.
