release 390

The tag 'release 390' refers to NVIDIA's Release 390 driver branch, which was the final driver series to support 32-bit operating systems. After Release 390, NVIDIA ended driver support for 32-bit OS platforms, meaning later driver versions will not install or operate on 32-bit systems. This change affected users running 32-bit versions of Windows and other operating systems, as driver enhancements and optimizations after Release 390 were not backported. The tag is relevant for discussions about legacy driver support, GPU compatibility, and the transition away from 32-bit computing in the context of NVIDIA graphics drivers.
