Any Priority @Epic? Not just VR but cube captures could gain performance.
hmm, good question.
I’m also interested if/when this makes it into the engine 
Would be a reason to actually get a new GPU 
Since the SMP is Nvidia privately owned, I think Epic will not make an official integrated.
I find the Github of NvPhysX/UnrealEngine has a branch called VRWorks-Graphics-4.12, it has integrated the feature Lens Matched Shading (LMS), Single Pass Stereo (SPS) which was based on the Simultaneous Multi-Projection (SMP) engine.
What I am interested is the simple Planer Projection on multi monitor screens based on SMP. I’ve download the Nvidia VRWorks sample code and have a check, since I’m no rendering engineer, all I can do is waiting and hope someone can integrate it.
