Rotating Penguin - the developer of GZ3Doom - has just released a brand new update that improves the experience in VR, specifically by making menus easier to read and by tweaking the games head-tracking.
◾Avoid camera problem when viewing Rift mode without an actual Oculus Rift attached.
◾Merge latest changes from GZDoom upstream
◾Apply late-scheduled head tracking, to reduce latency, to make menu viewing more comfortable, and to reduce nausea in doom mods that force head position.
◾Elevate per-eye camera shift from OpenGL-only, up to renderer camera, to avoid missed textures in culling.
◾Reset pitch and roll when leaving rift mode.
