CUDA Compute 1.3 Global Atomics Profiled

Got the GT275 in yesterday, was very exciting to move up to a card which has what might be 8x the ALU capacity of what I normally have at home and at work (I use a GPU with similar performance to the PS3 and 360). First test I ran was my point based Atom engine, and sure enough only a 2x frame rate improvement. As I expected, likely the engine is fully triangle setup (for points) bound, and couldn't make use of the added bandwidth and ALU capacity. Hence the interest in CUDA/OpenCL/DX11 CS, I'm currently limited by the fixed function hardware on high-end cards.
