1. Checking Frame Rate and Response Time 

The app should feel fast and natural. Measuring frame rate and response time helps confirm that everything runs smoothly during interactions.

2. Monitoring Heat and Battery

Long usage can lead to overheating or fast battery drain. Testing under continuous use shows how well the app handles time and power.

3. Testing with Complex Scenes

When an app has many 3D objects or animations, performance may drop. Adding heavy scenes during testing shows how stable the app really is.

4. Verifying Spatial Tracking

In MR, the app must stay in sync with the real world. Testing spatial accuracy ensures that digital content lines up with real-world positions.

5. Identifying Memory or Graphics Issues

Tools like Unity Profiler help find memory leaks or rendering problems. Fixing these improves app speed and reliability.

6. Trying It on Different Devices

MR apps should work well on more than one headset. Testing on multiple devices makes sure the app is consistent and smooth everywhere.
