Oculus VR has said time and time again that latency is the enemy of high-quality VR experiences, and the company's new 0.7 SDK for the Oculus Rift headset offers a new "Direct Driver Mode" that should help.
Developed in collaboration with GPU providers Nvidia and AMD, it allows the headset to address compatible graphics cards directly -- rather than at the OS level. Beyond boosting performance, it should also reduce conflicts with other software, Oculus reports.
There's a big risk in the upgrade, however: "as a result of these underlying changes, the 0.7 runtime won’t support applications built with SDK 0.5 or earlier, including all current content built with Unity 4.x," the company warns.
