Here is NVIDIA's response to the 81.26 driver that has recently surfaced on the web.
“NVIDIA is continually releasing drivers to our OEM partners, ISVs, and developers for testing and evaluating new NVIDIA products and new software applications. This driver v81.26 that has appeared on the web is not reflective of the final driver stability quality that NVIDIA will release, so many of the application problems that users are reporting are a result of alpha driver.
NVIDIA recommends users continue to use official drivers from our websites: NVIDIA.com or nZone.com. These drivers have been thoroughly tested by our QA and performance labs.
Please continue to check back on our websites for new official drivers from NVIDIA that will be released in the near future.”
