The Graphic Card created for Virtual Reality:

VR Direct in a nutshell is a collection of technologies and software enhancements designed to improve the experience and performance of virtual reality headsets such as the Oculus Rift. From a practical perspective NVIDIA already has some experience in stereoscopic rendering through 3D Vision, and from a marketing perspective the high resource requirements of VR would be good for encouraging GeForce sales, so NVIDIA will be heavily investing into the development of VR technologies through VR Direct.

From a technical perspective the biggest thing that Oculus and other VR headset makers need from GPU manufacturers and the other companies involved in the PC ecosystem is methods of reducing the latency/input lag between a user’s input and when a finished frame becomes visible on a headset. While some latency is inevitable – it takes time to gather data and render a frame – the greater the latency the greater the disconnect will be between the user and the rendered world. In more extreme cases this can make the simulation unusable, or even trigger motion sickness in individuals whose minds can’t handle the disorientation from the latency. As a result several of NVIDIA’s features are focused on reducing latency in some manner.

First and foremost, for VR headsets NVIDIA has implemented a low latency mode that minimizes the amount of time a frame spends being prepared by the drivers and OS. In an average case this low latency mode eliminates 10ms of OS-induced latency from the rendering pipeline, and this is the purest optimization of the bunch.

Meanwhile at the more extreme end of the feature spectrum, NVIDIA will be supporting a feature called asynchronous warp. This feature, known by Oculus developers as time warp, involves rendering a frame and then at the last possible moment updating the head tracking information from the user. After that information is acquired, the nearly finished frame then has a post-process warping applied to it to take into account head movement since the frame was initially submitted, with the ultimate goal of this warping being the simulation of what the frame should look like had it been rendered instantaneously.

From a quality perspective asynchronous warp stands to be a bit of a kludge, but it is the single most potent latency improvement among the VR Direct feature set. By modifying the frame to account for the user’s head position as late as is possible, it reduces the perceived latency by as much as 25ms.

NVIDIA’s third latency optimization is less a VR optimization and more a practical effect of an existing technology, and that is Multi-Frame sampled Anti-Aliasing. As we'll discuss later in our look at this new AA mode, Multi-Frame sampled Anti-Aliasing is designed to offer 4x MSAA-like quality with 2x MSAA-like performance. Assuming a baseline of 4x MSAA, switching it out for Multi-Frame sampled Anti-Aliasing can shave an additional few milliseconds off of the frame rendering time.

Lastly, NVIDIA’s fourth and final latency optimization for VR Direct is VR SLI. And this feature is simple enough: rather than using alternate frame rendering (AFR) to render both eyes at once on one GPU, split up the workload such that each GPU is working on each eye simultaneously. AFR, though highly compatible with traditional monoscopic rendering, introduces additional latency that would be undesirable for VR. By rendering each eye separately on each GPU, NVIDIA is able to apply the performance benefits of SLI to VR without creating additional latency. Given the very high performance and low latencies required for VR, it’s currently expected that most high-end games supporting VR headsets will need SLI to achieve their necessary performance, so being able to use SLI without a latency penalty will be an important part of making VR gaming commercially viable.

On a side note, for the sake of clarity we do want to point out that many of NVIDIA’s latency optimizations come from the best practices suggestions of Oculus VR. Asynchronous warp and OS level latency optimizations for example are features that Oculus VR is suggesting for hardware developers and/or pursuing themselves. So while these features are very useful to have on GeForce hardware, they are not necessarily all ideas that NVIDIA has come up with or technologies that are limited to NVIDIA hardware (or even the Maxwell 2 architecture).

Moving on, other than NVIDIA’s latency reduction technologies the VR Direct feature set will also include some feature improvements designed to improve the quality and usability of VR. NVIDIA’s Dynamic Super Resolution (DSR) technology will be available to VR, and given the physical limits on pixel density in today’s OLED panels it will be an important tool in reducing perceptible aliasing. NVIDIA will also be extending VR support to GeForce Experience at a future time, simplifying the configuration of VR-enabled games. For VR on GeForce Experience NVIDIA wants to go beyond just graphical settings and also auto-configure inputs as well, handling remapping of inputs to head/body tracking for the user automatically.

Ultimately at this point VR Direct is more of a forward looking technology than it is something applicable today – the first consumer Oculus Rift hasn’t even been announced, let alone shipped – but by focusing on VR early NVIDIA is hoping to improve the speed and ease of VR development, and have the underpinnings in place once consumer VR gear becomes readily available.
