WDDM 2.0 drivers and Rift dk2 support.

I know I've been complaining a lot, and for that I apologize. Last night I became a man possessed. I want to be the first person outisde of AMD and Nvidia themselves to use DX12 and the rift in glorious harmony.

My background is a hardware platform and solutions provider. I was one of the first people using AMD's eyefinity and surround, we built simracing rigs, we played around with TrackIR in the early days for our end users.

I now work in software QA in digital signage across 4 operating systems, so testing betas is what I do. But that's a whole other level.

In my spare time I still love to test bleeding edge hardware. I also like to come up with solutions and fixes for complex hardware issues.

I've written fixes for motherboard bioses. I've Jtagged firmware onto harddisks and saved may a raid stripe in my day. I've compiled custom drivers from source to make webcams from windows 95 work on windows 8.1 64bit. I know my way around this stuff.

The community should know that OVR could release a beta display driver injector for the Rift, on windows 10, which would unlock the potential of directX 12's massive improvements across the board (even on non dx12 titles) with about 15 minutes of work.
Obviously they should do some internal QA, but seriously, JUST REPACKAGE THE DRIVER FOR WDDM 2.0.

Microsoft is providing the DSK for free right now. EVERYTHING except the display profile already works in windows 10, on direct x12, tracking, morph, everything. The only thing that needs to be updated is the extended mode display driver to fit the timing of the virtual monitor that the oculus creates. The HMD is detected properly in everything but extended.

I took the time to create a WDDM 1.2 compatible inf for you.

here you go:

Now, if you turn off signature enforcement, this driver will install and help the rift work in extended mode on windows 8.1 and 7 and so on.

However, because oculus display driver is actually INJECTED into the display driver itself, (really just riftenabler.sys, and it's companion inf), it's unable to properly setup the monitor timings necessary (as it's a pnp default) and you will get a flashing blue/amber light on the rift and errors in attempting direct to rift mode with calls to the 32bit aticfx dll in syswow64 and system32.

I suspect the reason for this is that the locations in the registry, as well as where display drivers in windows look to set the timing (as well as the calls to directX, opengl, etc) the driver have changed due to WDDM 2.0 only. Pre-configuring the rift as an ACTUAL display, should allow at least extended mode. This is why standard monitor inf/sys pairs still work in Wddm 2.0. In fact, by this logic they shouldn't, but I suspect windows imports the timings into the new registry locations, IF the EDID stored in the registry previously is valid (the rift's isn't, more accurately, it doesn't exist.)

The rift display driver is the one thing we don't have the source for, and of course I understand why, but why not get this poppin? Simply make a detection for dx12 + wddm 2.0 and write the changes to the driver. At least extended mode would work.

The Display driver examples for KMOD WDDM 2.0 can be found over at microsoft's github:

https://github.com/Microsoft/Windows-dr ... ideo/KMDOD

But I suspect you don't need to go that far. All you need to do is make a display miniport driver visible to the other WDDM components that are now in play - by changing your inf and adding a few lines to the sys.

I didn't have time to modify this for you because I had to go to work. Hopefully my lack of sleep today will be valuable to someone over there.
