Hello, I'd like to consult everyone about abnormal frame rate issues encountered during Vision Pro usage, along with questions regarding refresh rates. I hope to gain insights or solutions:
My VP (M5) device experiences sudden frame rate drops during operation, with the following specific symptoms: During initial operation, the frame rate is approximately 90 frames per second, providing a smooth and normal user experience; However, it subsequently drops unexpectedly to 45 FPS, causing noticeable lag that severely impacts usability.
Actual usage logs provide a clear timeline: During the first session (23:47:35–23:57:41), the frame rate remained consistently stable at 90 FPS; After pausing usage for a period and restarting the device (00:22:30–00:30:47), the frame rate initially remained stable at 90 FPS. However, starting at 00:30:48, the frame rate suddenly dropped to 45 FPS and remained at this low rate until 00:36:18.
Additionally, we have two further questions:
- What could cause this sudden, unexplained drop from 90 FPS to 45 FPS?
- Our team has multiple VP M2 devices of the same model and noticed that some default refresh rates are 90Hz while others are 100Hz. What factors determine the frame rate of these devices? Why do refresh rate differences occur among identical models?
Have others encountered similar sudden frame rate drops? If so, could you share potential causes and troubleshooting approaches for resolving such issues? Thank you very much!
