I'm guessing the whole point of this is to boost AI. Pre-RTX have no tensor cores, therefore it would be a waste of time to open source.

I guess it's the GSP which isn't there on the pre rtx cards. Also, most of the stuff is moved into the firmware as a blob (hence the need for the GSP) so the drivers are not really open open. But it's still a refreshing move

I was kind of hoping that Pascal and Volta would still be included, given how much of a userbase still has those, however from Nvidia's standpoint, I can kind of see it? These are almost a decade old. But either way, i'm sure they have some other corporate bullshit in mind
