It's Silence, Silence Everywhere.
What I found interesting in changelog of the REDUX ver. is that ver was a VR mode (supported ? dunno how to tell it correctly) before patch 1.01.
But with the patch 1.01 we got.
Patch Redux Edition 1.01 (17.09.2015)
Scale resolution 150% added, great cost/effect ratio
Proper mouse behavior in menus (no extra click needed)
Fixed re-assigning keys to arrow keys
Perma-config, no longer requires the load of a savegame
Water Reflections can now be turned off
Smart Crosshair turns off in the outro
Fixed the fog flash after Start New Game
Proper display of graphics options on a fresh install
Language now remembered 100% of the time
Smaller visual and code/script fixes
Disabled VR support
So my ninja skills tell me that the possibility of VR Ethan can happen on GoG, but it's up to dev to implement it.
