Nvidia is dropping support for 32-bit system after Version 390 of its graphics driver. This is somewhat earlier than expected, but most computers have already moved to 64-bit operating systems. Although, it may prove troublesome for some legacy machines.
This isn’t to say that Nvidia is dropping 32-bit immediately. The company will still be providing security updates for the older systems for a year.
What changes here is that many organisations still stick to 32-bit operating systems because those support the running of 16-bit programmes. Something that newer 64-bit systems do not. Even 32-bit applications don’t run in a 64-bit environment without some tweaking or a virtual environment.
Nvidia’s change affects all operating systems, including older versions of Windows, Linux, and FreeBSD. Not that the average consumer should notice any difference in their setup. Most people who regularly update their drivers should already be on 64-bit operating systems; since that’s the only way to get the most out of having more than 4GB RAM.
