FuzzleSnuz Posted March 31, 2022 Share Posted March 31, 2022 (edited) This was a hot topic back in 2012, and we all know how Microsoft gave up halfway when they brought the D3D11.1 API to Win 7 but didn't bother bringing WDDM 1.2 along with it. That was now ten years ago. Since then, especially in recent years, there have been some great projects that make the better versions of Windows remain viable in these dark, modern times. I'm thinking of things like the extended kernels for Vista, the Win 8 xHCI driver stack brought to Win 7, and even 12on7 by Microsoft themselves. I even see some talk about making extended Win 7 and 8 kernels now, given that the right person (or people) with the right knowledge shows up to do it. Given the recent progress with these kind of things, I would like to know if anyone, anyone at all, is aware of a current-day effort to get WDDM 1.2 functional on Windows 7. By functional, I mean something that makes it possible to install a Win 8 graphics driver in order to benefit from the improvements in WDDM 1.2, like the superior GPU preemption model. For certain graphics applications that abandoned Win 8 early but kept Win 7 support, this would be an incredibly helpful thing to have.

Some versions of Autodesk Maya. For Maya, it's not a technological support issue but rather a "we only bothered testing on Win 7 and 10" kind of thing. There isn't any anti-Win8 behavior as far as I can tell, but there could be a mountain of showstopping bugs that aren't immediately evident. It was a decision driven by the leverage of Autodesk's enterprise clients, who were only using 7 and 10 at the time and thus pressured Autodesk to do the same. This isn't uncommon.

Microsoft decided to do a freebie ESU program for 365 on Win 7. Ofc 365 is dysfunctional spyware and I use 2010 whenever I can. Link to comment Share on other sites More sharing options...
