If you are trying to do computations with shaders and then read back the
results to CPU local memory be prepared for massive disappointment. Reading
back through PCI or AGP bus is excruciatingly slow and has massive
latencies.

Your best bet is to render to floating-point rendertarget (=texture) and
read it back and interpret the results. But this approach obviously is very
limited and "reading back" involves not only beginframe, rendering, endframe
and the latency that is associated with that, but also the slow extraction
of the data from the textures in GPU local memory.

Good luck..
