Following a declaration that it would stop releasing GeForce graphics card drivers for 32-bit operating systems, which came at the end of last year, Nvidia has confirmed that support will officially cease before the end of April.

This affects 32-bit versions of Windows 7, 8/8.1 and 10, as well as Linux and FreeBSD, although important security fixes will continue to be provided running through to the beginning of next year.
