Pls let me know how it's working for you on Discord.

Beta features
Expect bugs and performance issues at this stage.- Calibration eliminated!
- Better wing controls: roll naturally with your wrist instead of triggers
- Temporal Super Resolution - save on FPS by turning down render resolution without much visual quality loss
- Better lighting with extremely long distance shadows
- Better day/night sky graphics
- High quality volumetric clouds you can fly through and above
- Dynamic weather system with rain, thunder, lightning, fog, and cloud coverage
- Weather clears above the cloud layer
- Better flight physics
- Proper graphics options
- Little tutorial guys
- Returning to massive finite landscapes with more human touch in their design.
Infinite procedural generated landscapes are being removed because they are too much of a performance burden and not reliable with some of the new landscape features like rivers, waterfalls, and mountain lakes that I'm working on.
- Better grass
- Better groundcover
- Better ambient audio
- Fast-forward time from the popup menu
- Better landscape detail
- OpenXR instead of the older SteamVR/Oculus targets
These features from the Unity version are not in the UE5 Beta yet but I'm working on it:
- Talon controls
- Hunting rabbits
- Glowy deer
