BTW, the wddm 2.1 is for fix memory addressing issue. It is about virtual addressing thing with MS. It didn't work under wddm 2.0 fine because of 4KB vs 64KB addressing issue of nvidia hardware.

Means less crash from now on Nvidia hardware than before with the same software.


Just a bit of hint, Vulkan Fermi support has been cancelled because of this issue and Nvidia wasn't aware of it. Instead, they have released some sort of new update in Vulkan pr project press, with out Fermi.
God bless NV software engineers

Article says, should work with : physical page size

As mentioned previously the video memory manager supports two page sizes. System memory is always managed in 4KB pages, while memory segments may be managed at either 4KB or 64KB granularity as determined by the kernel mode driver. In the real word, 4KB isn't working with NV hardware. That is why came up with WDDM 2.1 .

God bless anandtech, guru3d and other tech sites to be silent in this matter over a year


Just to get this up , memory management is not really working with WDDM 2.0 with the current state of support from both MS and NV.

So much of the truth from NV . This company tells you nothing if possible to keep it behind the doors.
