How to Optimize XR Performance in Unreal Engine 5 for VR/AR Devices?

Hi everyone,

I’m diving into XR (Extended Reality) development using Unreal Engine 5 for a VR/AR project and I’m running into a few performance issues that I hope you can help with. As a newcomer, I’m looking for advice on optimizing performance and ensuring a smooth user experience across various XR devices.

  1. What are the best practices for optimizing performance in XR projects in Unreal Engine 5, specifically when targeting devices like Oculus Quest 2 and other standalone headsets?
  2. Which rendering settings should I tweak in UE5 to ensure smooth performance in VR without sacrificing too much visual fidelity? I’m particularly concerned about maintaining consistent frame rates (minimum 72 FPS) for VR.
  3. How do you handle high-fidelity assets (like complex meshes or high-res textures) in XR environments, especially for larger scenes, without causing performance dips in VR?
  4. What’s the best approach for UI/UX design in XR? I’m looking for advice on ensuring user interactions feel natural and comfortable in both VR and AR, without breaking immersion.
  5. How do you optimize AR experiences, particularly for issues like motion tracking, lighting, and device limitations such as field of view and image recognition?
  6. How can I integrate ARKit/ARCore into an Unreal Engine 5 project, and what performance trade-offs should I expect with these plugins in XR development?

Any insights or advice from your own XR development experience would be incredibly helpful! I’m eager to learn the most effective ways to improve performance and create a polished experience for my users.

Thanks so much! :folded_hands:
