At our company we are supporting somewhere close to 30 different configurations of graphic cards. So having a concise list of "Legacy" drivers is very handy when a machine needs a rebuild. If the legacy driver is not available the latest will get install and usually will require downgrading to the Legacy driver if you can locate it anywhere.
Locating the newer systems drivers is easier than located a Legacy driver. So if PTC could maintain this information for archive history. All customers could benefit.
Nvidia provides a location to search for Certified driver for PTC as a partner but the available drivers are limited to newer hardware. I will give kudus to Nvidia support when I have requested a legacy driver they usually will provide a link. Just requires waiting a day or so to get the response.
