Did you already test SVP with the latest NVIDIA driver that was just released and see performance improvements or decresement?
Thank you for information about new WHQL driver 295.73. I tested 280.* and 285.*. All of them are slower than 275.33 (see details).
I will compare new driver with 275.33 soon.
I looked at Quadro drivers description. It is nothing new for 3 months: 3 last versions has the same text in Release Highlights: 276.28, 276.42, 276.52. The latest driver relates to R275 driver-set. It is the indirect confirmation that there is still no performance increase in 280.*, 285.* and 295.* driver-sets.
In official R295 release notes which consists of 60 pages I found only one place at the page 59 by searching "OpenCL". It is "OpenCL Notice" title
There is no changes declarations of OpenCL in R295.
