I was wondering if some one could tell me about how I could get a 3d card and drivers for dos.
Also, has anyone came up with a way to use a second core of a two core processor as a virtual video card?
Thanks.

No. What's your goal, here? Maybe someone solved it a different way, and asking about method is getting in your way. Problem is video card architecture is different than standard general processor - it's hard enough to separate out one core of a CPU, it'd be a bigger task to do that with the specialized GPU chip, and you'd still need full driver support if the hardware supported it. Sometimes you hear about using the GPU for other tasks, like calculating bitcoin hashes or other math (GPUs are good at iterative math!), but that's just using shader and programmable pipeline technology, not actually getting into the processor and doing whatever you want. (AFAIK from what I've read, IANA(GPU architect or programmer)!)Also, has anyone came up with a way to use a second core of a two core processor as a virtual video card?
