NVIDIA GTX 980Ti and GameWorks VR

Yesterday I was in Geek heaven trolling through computer parts to build a Virtual Reality ready PC that is fast, powerful and quite. What a difference a day can make because the rumored NVIDIA GTX 980Ti will be available for ordering within the week.

The GTX 980 Ti is “almost” as fast as the mighty Titan X but $350 cheaper at MSRP of $650. The main difference between the two cards is 6 GB of GDDR5 memory vs. the 12 GB on the Titan. NVIDIA also announcemed a new VR software development kit (SDK) called GameWorks.

NVIDIA Adds GameWorks VR

To help improve the VR experience, NVIDIA have created “GameWorks VR” SDK for VR headsets and game developers that improves performance, reduces latency, and improves compatibility. GameWorks VR includes the following technologies:

Multi-Res Shading
An innovative new rendering technique for VR whereby each part of an image is rendered at a resolution that better matches the pixel density of the final ‘warped’ image (VR images are an oval instead of a rectangle, as seen on a desktop monitor). By using Maxwell’s multi-projection architecture to render multiple resolutions in a single pass, substantial performance improvements are seen in VR games.

Context Priority
Enables control over GPU scheduling to support advanced virtual reality features such as asynchronous time warp, which cuts latency and quickly adjusts images as gamers move their heads, without the need to re-render new frames. This results in a smoother, more responsive experience that makes VR more comfortable to use, especially over longer play sessions.

With VR SLI, multiple GPUs can be assigned a specific eye to dramatically accelerate stereo rendering. VR SLI even allows scaling for PCs with more than two GPUs.

Direct Mode
Plug and play support for upcoming virtual reality headsets ensures instant support the second they’re connected to a PC and treats them as separate device, rather than an extension of the Windows desktop as currently seen on some system configurations.
