never mind my last comment. Restarted vorpx, now it came up. Was able to find and fix the broken shader by applying matrix invert mode to it. Now enjoying the game in full G3D, that was awesome, thank you again Ogrescar.
hm, i was able to apply Base Unity 5 profile. Works pretty well out of the box. Z3D looks realy good. G3D too, also almost without performance loss. However in G3D shadows seem to be off a little. Guess some shader needs to be fixed.
But i wasn’t able to activate the shader authoring page as described in the guide. I have activated both “Expert Settings” and “G3D authoring”. But pressing CTRL+END does nothing. Any help on that?
3D Vision requires/required a stereo profile for a game before it would work, which essentially required collaboration between the game developer and nvidia
Yes, but there was helixvision.
Geometry 3D adds a second camera (one for each eye) to give stereo vision. This is why it looks most real and cost double performance.
It sounds obvious, but…
I was using Nvidia 3d Vision before it was dumped by vendor. It was in fact doing real Geometry 3d, not Z3D for sure. And the performance was dropping only by like 10-15%. Rendering a second cam should not cost double performace, as most of the rendering of the scene can be shared between both cams, and only at final rendering stage it needs to be separated.
Also games that are made specially for VR, are actually real 3d and they run on my same machine on max graphics and high resolutions at maximum frame rates. Even though, they also need to render two eyes.
I was expecting performance drop with vorpx when using G3D, but not that much. In example Farming Simulator 19 on same machine, was running for me with Nvidia 3d Vision at 60fps at maxed out graphics stable. While with vorpx G3D it breaks down to something like 10fps. Even with lowest graphics settings and lowest resultion its not going higher then 30 but of course looks like mess. With Z3D runs smoothly at 60 fps with max settings and high res. G3D kills the performance for FS19 completely it’s not just halving the performance, it kills it completelly. So actually even though G3D is available for FS19 it is in fact unusable.
I assume therefore that the method how vorpx realises G3D certainly has some issues with the performance, and it cannot be justified by just saying, well it has to render everything twice. No it doesn’t. If it does it, then its not an optimal solution.
I am suspecting, that G3D breaks the performance in vorpx because it actually renders everything 3 times from scratch and is not sharing ressources. Don’t forget the monitor. I have a reason to believe that monitor is rendered compeletely separately. 1. It runs a different resolution. 2. When changing camera hight in vorpx G3D settings, it does not affect the monitor, you see it only in VR.
