Nvidia to cease producing new drivers for 32-bit systems [arstechnica.com]
While most people have probably made the switch by now, yet another reason to drop 32-bit operating systems and move to 64-bits is coming. Version 390 of Nvidia's graphics drivers, likely to arrive in January, will be the last to contain support for 32-bit versions of Windows (7, 8/8.1, and 10), Linux, and FreeBSD.
There will be another year of security updates for 32-bit drivers, but all new features, performance enhancements, and support for new hardware will require the use of a 64-bit operating system and 64-bit drivers.
