This plugin retrieves the camera position from the VR headset and moves the X-Plane camera to match that position. It then captures a screenshot and uploads it back to the VR headset.
The goal is to achieve extremely high performance with minimal latency.

I used "X-Plane SDK 4.2.0 for Windows, Linux and Mac ZIP (X-Plane 12.3.0 & newer)"
I used version: Version 16.3
Most likely other version should work fine too.
Most likely if you build it for x86_64 too it will support X Plane 11 too. You might also need to use an older SDK version but maybe not.
