Hi Michael,
Thank you for both the re-post and the answer.
I read that in HSLS 3.0, the keyword "double" was removed, which seems an antithetical move given the trend in hardware.
Nonetheless, I further understand that DirectX 10.1 was chiefly motivated by AMD-ATI for this specific line of cards--hence, these are the only 10.1 cards on the market today.
But, after just a little research, I see that I can supply "untyped" buffers to the card and execute pixel shaders against them. All I need to do now is see if I can receive the data as streams of doubles. A little testing should give me the answers I need.
I downloaded your SDK yesterday and experimented with it, but it crashed my video card after running just one sample. I am using a single card for both Video output (in Vista 64) as well as GPGPU processing. If the card works well, I will buy a second and use it as a dedicated GPGPU board.
If you hear any more on this topic, please post back to this thread, as will I, so we can all keep up to date 🙂
Thanks again,
Scott
