The news that Oculus SDK 0.7 would incorporate Direct Driver Mode after the August 20th update is not very old and now NVIDA has announced the availability of the beta version of their GameWorks VR. As mentioned on this podcast, until now your GPU has treated the Oculus as a secondary monitor but with this update your graphics driver will directly talk to the Oculus as a separate device, which should help greatly with latency and development of the tricks and treats yet to be discovered when programming for this type of interface.
NVIDIA's Gameworks VR, as well as AMD's LiquidVR will provide a platform for developers to program for the Oculus Rift as well as the competeing products from other companies. The new beta SDK from NVIDIA has been updated to support VR SLI and is compatible with the new 350.60 Game Ready drivers. Programmers working with the Maxwell architecture will benefit from Multi-Res Shading which should increase the performance of your current programs.
