VR Comfort Calculator: FPS & Motion Sickness

How it Works

The tool compares your 'FPS' against thresholds established by headset manufacturers. Standards: * < 72 FPS: High risk of nausea. * 72-90 FPS: Acceptable for most (Quest standard). * 90+ FPS: Optimal comfort (PCVR standard). * 120+ FPS: Hyper-smooth.

What is VR Comfort Calculator: FPS & Motion Sickness?

Virtual Reality induces motion sickness when there is a disconnect between visual input and the vestibular system (inner ear). Low frame rates (FPS) or high latency cause this sensory conflict. This calculator evaluates your system's performance metrics against industry standards for VR comfort.

Step-by-Step Guide

1. Input FPS

Enter your average frames per second in VR.

2. Select Headset

Different headsets have different refresh rates (Hz).

3. Analyze

The tool determines the comfort level and risk.

Example

Input: 45 FPS, Quest 2

Result: Risk: High (Reprojection Active)

FAQ

What is Reprojection/ASW?

Techniques to fake frames when FPS drops (e.g., 45 FPS becomes 90Hz). It can cause visual artifacts.

Why do I feel sick?

Sensory mismatch. Your eyes see movement, but your ears don't feel it.

Is 120Hz better?

Yes, lower latency reduces motion sickness for sensitive users.

What affects VR FPS?

GPU power, resolution scale (Supersampling), and game optimization.

Does IPD matter?

Yes, incorrect Interpupillary Distance causes eye strain, not low FPS.

Conclusion

Maintaining a stable frame rate is critical in VR. Unlike flat screens where 30 FPS is playable, VR requires 72-90 FPS minimum to maintain 'presence' and prevent nausea. If your FPS is low, lower graphical settings before resolution.
