Comparing 430.xx to 418.74, looking at the list of devices supported as documented in the readme, I have noticed that the 430 series drops support for:
I suspect someone hit the key. Otherwise I must be hallucinating because 430.26 works fine on my “unsupported” GT740M which is also gone from the list.
ProdID 1292, there are only some Lenovo specific desktop 740A left, the generic 740M is gone. Furthermore 1291-1293 all use the same GK208M chip so the changes don’t make any sense at all.
Makes for an interesting speculation, though. Maybe this is the advent of a new legacy driver, retiring Kepler. Looking at the support timeframes, there have always been two legacy releases and the support for the 340 driver ends by 12/19.

Now look what I found:

So looks like Kepler mobile chips are already depreciated/obsoleted in some way so this wasn’t completely unintentionally. Since this still works on mine, this might be just affecting Windows for now since “game ready drivers” are mentioned. Looks like the same mess as with 3D-Vision. The usual internal communication failure, it seems.
Nvidia finally replied by email, also referring to that link.
I guess “Game Ready Driver” means “latest driver” (i.e. 430 series), for which it says that desktop Kepler is supported but mobile Kepler is not. Maybe the remaining 1292 devices still listed in the README are desktop devices? Is yours a desktop device?
The “Game Ready Driver” is the Windows graphics driver. Like said That 740A in the list is a specific desktop gpu derived from the mobile chip, I’m running a generic 740M mobile gpu. Also, another user already noticed his mobile Kepler gpu being removed from the list despite still working.
So we can safely assume that drivers >418 on Windows dropped some features like mobile Kepler support and 3D Vision while the Linux driver still supports this since this would require to create a new legacy driver which is always work for the nvidia devs to maintain it so the number of concurrent legacy drivers will be kept low.
As a conclusion and a happy owner of that said ‘unsupported’ mobile Kepler gpu which just got render offload I can only state that there are wise and not-so-wise questions you can pose to a company, sleeping dogs and such.
wise question: your docs tell that my device is still supported, yet it doesn’t work, why?
not-so-wise question: your docs tell that my device is unsupported, yet it works, why?
for more info, take a look into the Adobe-Flash-Linux-legacy stuff, maybe you get the picture.
These “forgotten” GPUs are not listed there at all. Strange.
I looked for GeForce GTX 765M (10DE:11E2), which one of our users has, in that file. It was missing there, although was listed as supported in the readme for 418.x.
The user checked that v440.x of the drivers seems to work OK with that GPU, but still, it would be good to know the official status.
