Right, so, which should be supported? CUDA, Stream, OpenCL, or do we
just do things with shaders and hack tricks in DirectX and OpenGL? Do we
go lower than that, skip the OS, and make POV-Ray something that runs at
a very low level, accessing the hardware in assembly just to get every
bit of speed and capability from the architectures? Support your answer
with examples of benefits and potential problems that will be faced
along the development path. Discuss the impact that future GPU
capabilities, such as shorter buses, integration into the CPU, and
branching, will offer.
