Hi,
With the current stable version 21.3.5 I was able to run the DX11 version including the FPV mods, but there was no grass/trees/etc, no matter what profile I tried. I think this must be something related to VorpX – when I ran the same without VorpX, the grass was there.
With 21.1.0 I’m not able to run at all, unfortunately. It offers to install a mod of its own, but that won’t compile (even on a clean Witcher 3 install, no mods). If I choose not to use this, it won’t start, saying it could not initialize the Vive libraries.
So, there is currently no way for me to run the Witcher 3 using VorpX…
