I asked them by email about 2 months ago. The reply I got back was at this time there no plans for a windows 10 driver
You asked who specifically? NVidia is a huge company with hundreds of sections and thousands of people who do one specific job and might not exactly know what's going on in others...
I don't know if it's new or not but they pushed out an official Windows 10 driver for the 7xx series this morning so they may have for other series too. 353.30
I don't know who I asked. I went on nvidia site and found it email address for support. But doesn't matter now. Since a Windows 10 driver has been released
