Interestingly, if NVidia do an RTX card with VR in mind then GameWorks / VRWorks will be used. One good thing about that is VRWorks has VR-SLI support built in, that and the new “VR Port” could all be tied together.
This reminds me of the 3DFX evolution. Maybe this is the next turning point as we teeter on requiring huge change in the way we generate graphics as the technology/future is once again taking a new shape.
I do wonder how AMD will cope though. Their Vega cards are actually very good at real-time ray-tracing but if they can not access VRWorks / Gameworks like they can with DirectX then what? Huge license fees demanded by NVidia so AMD card cost will go up? AMD writing their own ray-trace SDK?
