If you're one of the lucky b... er, few that have a GeForce GTX 1080 on preorder, you're in luck. The first official driver for the GTX 1080, version 368.25, is out now in preparation for the card's launch, and carries a WHQL certification badge.
The new driver is essentially similar to the 368.22 release we covered recently, but doesn't just add "GTX 1080" to its list of supported cards. Nvidia's new VRWorks features are now enabled in systems using the new graphics card.
What are those features, you say? Well, first there's Lens Matched Shading, which Nvidia says will offer a "substantial" pixel shading performance improvements by rendering to a surface that more closely matches the final warped version that your eye(s) will see.
Then there's Single Pass Stereo, which avoids having the GPU process the same geometry twice just because there are two viewports instead of one. According to Nvidia, Single-Pass Stereo ought to cut down the GPU's geometry workload in half when compared to current VR geometry shading techiques, as tesselation and vertex shading will only have to be done once for the whole scene.
