Rendering Performance: 3D vision vs VR
Hello everyone, I just want to know why 3D vision performance is not as the same as VR when upgrading to new architecture, when we compare Kepler vs Maxwell vs Pascal there is a ~2x VR performance between each next architechture so I was wondering why it's not the same thing with 3D vision it's the same rendering* after all (stereo; rendering per eye) *i'm not really sure about that Thanks!

What you have linked is performance per watt. It's meaningless as you can't infer gaming performance from it.

VR will discard a lots of pixels in some areas: https://blogs.nvidia.com/blog/2016/07/21/rendering-foveated-vr/ https://developer.nvidia.com/vrworks/graphics/lensmatchedshading etc. If you would render the same thing as 3D Vision does in VR, you would see the exact same results, on the same hardware and performance degradation. VR needs to run at 90FPS otherwise it "kills" you! 3D Vision can run PERFECTLY fine at 30FPS without "killing" you! :)

VR uses different techniques to render as opposed to 3D Vision.
3D Vision will always render the same 2 TIMES, FULL frames, NO PIXEL DISCARD.
VR will discard a lots of pixels in some areas:

https://developer.nvidia.com/vrworks/graphics/lensmatchedshading


etc.

If you would render the same thing as 3D Vision does in VR, you would see the exact same results, on the same hardware and performance degradation.

VR needs to run at 90FPS otherwise it "kills" you!
3D Vision can run PERFECTLY fine at 30FPS without "killing" you!
