Support for Wide FOV VR headsets (removing Frustum Culling issue)-

@legia92
I believe this is a more general VR problem solely due to FS2020.

In effect, with the last few SteamVR version you can limit the FOV and when I reduce it to 50% in SteamVR with the Index, I can see FS2020 is over-culling the objects too early on the sides. In other words: with SteamVR FOV set to 50% trees (for example) are disappearing before reaching the edge of the view when turning the head around.

NB: In my opinion there is a logical possibility the game could be under-culling objects with any VR device with more than 90 deg FOV therefore. If this is the case, the game could actually be delivering lower performance in VR because it would be processing unnecessary objects.

NB: The inverse effect if happening with the selection of object LODs. In short, it displays highest details (lowest LOD) if the object is at 45 deg from center, and the next LOD (lowest details) if the object is at the center.

Here are more details about this (with screenshots):

I don’t know whether this has anything to do with the many other LOD problems, but it seems these are still prevalent and still not fixed.


For what it’s worth, here is a compilation of topics I’ve already posted:
