February 27, 201115 yr First let me say this, I've been running an nVidia GTX-560 TI and am completely satisfied with it's performance in FS9. Simply stellar. Now my TI has 384 CUDA Cores while the GTX-570 has 480 and the GTX-580 has 512. So how does an increase in CUDA cores help performance?Mark

February 27, 201115 yr Hi Mark. Have a look at this link. It should give you the basics of what CUDA is and how it's used in a much more simpler form than I could explain!http://gamecreator.blogspot.com/2008/06/what-is-cuda.htmlFrom what I can see, a program has to be specifically adapted to utilise CUDA to it's full potential; something that FSX can not. However someone with a more specialised knowledge might be able to help you more! Sam Crawford "Don't judge the intelligence of an individual by the number of posts that they have made.

February 28, 201115 yr Author CUDA.Ah, the veil is lifted. Now I see why the 570 and 580 cards not only have more CUDA cores but also have a larger memory interface width. I suppose that the larger memory interface width is to relieve any bottlenecks due to latency between the CPU and GPU interfaces. So more CUDA cores means more parallel processing. I found the following Wiki statement enlightening..."GPUs have a parallel throughput architecture that emphasizes executing many concurrent threads slowly, rather than executing a single thread very quickly."Thanks for the info gents!Mark

That was an interesting read...thank you!Mark

So you write once and compile twice, once for each processor CPU + GPU.
