Steam Frame Motion Sickness: Setup & Comfort Guide

Steam frame motion sickness is the dizziness or nausea some people feel when using the Steam Deck’s built-in frame motion smoothing feature, which interpolates frames to make gameplay look smoother. This guide explains what causes it, how to adjust your settings for comfort, and what to do if you still feel sick. You’ll learn the practical setup changes that reduce the effect without sacrificing visual quality.

What Is Frame Motion Smoothing?

Frame motion smoothing, often called frame interpolation, is a display technology that creates new frames between real ones to increase the perceived frame rate. On the Steam Deck, this feature is designed to make games look smoother, especially when the actual frame rate is low. It works by analyzing consecutive frames and generating intermediate ones, which can make motion appear more fluid. However, this synthetic motion can confuse your brain’s vestibular system, leading to motion sickness symptoms like headache, nausea, and eye strain.

Why It Causes Motion Sickness

Your brain relies on a combination of visual cues and inner ear signals to sense motion. When you see smooth, artificially created motion on screen but your body is still, the mismatch can trigger nausea. The effect is stronger when the interpolation is noticeable, such as during fast camera pans or quick character movements. The Steam Deck’s screen is small and close to your face, which increases the visual impact. Some people are more sensitive than others, but the underlying cause is the same: your brain perceives motion that your body doesn’t feel.

Practical Setup to Reduce Discomfort

If you’re experiencing motion sickness with frame motion smoothing enabled, try these changes in order:

• Turn off the feature: The most effective fix is to disable frame motion smoothing entirely in the Quick Access Menu (QAM) under Performance settings. This removes the artificial frames and returns to the original frame rate.
• Lower the interpolation strength: If you want to keep some smoothing, some games or system settings allow you to adjust the intensity. Lowering it reduces the visual artifacts and the chance of sickness.
• Increase the base frame rate: Use the Steam Deck’s built-in FPS cap or game settings to raise the actual frame rate. The higher the real frame rate, the less interpolation is needed, and the less noticeable the effect.
• Play in a well-lit room: Dim lighting can make the screen flicker more apparent, worsening symptoms. A bright environment reduces eye strain.
• Take regular breaks: Give your eyes and brain a rest every 20-30 minutes. Look at something in the distance to reset your focus.

Adjusting Steam Deck Settings for Comfort

Beyond turning off frame motion smoothing, you can tweak other settings to reduce motion sickness:

• Disable motion blur: Many games have a motion blur option that can exacerbate nausea. Turn it off in the game’s video settings.
• Reduce screen brightness: A very bright screen can cause eye strain. Lower the brightness to a comfortable level, but not so low that you squint.
• Enable the 60Hz refresh rate: If your game runs at 30fps, the screen refresh rate might be 60Hz. Some users find that setting the refresh rate to 40Hz (with a 40fps cap) feels smoother and less nauseating than 30fps with interpolation. Experiment with different refresh rates in the Quick Access Menu.
• Use the built-in FPS limiter: Set the FPS limiter to a value your game can consistently hit, like 30 or 40. This avoids frame rate fluctuations that can trigger sickness.

Common Problems and Fixes

Here are typical issues and how to solve them:

• Feature is greyed out: Frame motion smoothing may be unavailable if the game is running at a high frame rate or if the screen is set to a certain refresh rate. Check that the game is in fullscreen mode and the refresh rate is set to 60Hz.
• Game still feels laggy after disabling: If you turn off smoothing and the game feels choppy, it’s because the actual frame rate is low. Lower the game’s graphics settings to increase the frame rate.
• Motion sickness persists even with the feature off: This could be due to other factors like low frame rate, small text, or playing in a moving vehicle. Try increasing the frame rate, using a larger font, or playing in a stable position.
• Interpolation causes visual artifacts: When enabled, you might see ghosting or halos around moving objects. This is a known artifact of frame interpolation. Reducing the strength or turning it off is the only fix.

Comparing Frame Motion Smoothing to Other Options

Frame motion smoothing is not the only way to improve perceived smoothness. Here’s how it compares:

• Frame rate capping: Capping the frame rate to a stable value (like 30 or 40) can reduce frame pacing issues, making motion feel more consistent without interpolation. This is often a better choice for motion sickness because it doesn’t introduce artificial frames.
• Lowering graphics settings: Reducing graphics quality can boost the actual frame rate, which is the most natural way to improve smoothness. Higher real frame rates are always less likely to cause motion sickness than interpolated ones.
• Using an external display: Playing on a larger TV or monitor can reduce motion sickness because the screen fills more of your vision, but it can also make the effect worse if the display has its own motion smoothing. If you connect to a TV, turn off any TV-specific motion smoothing features.

Safety and Health Considerations

Motion sickness is not harmful in the long term, but it can be uncomfortable. If you experience severe dizziness, headaches, or nausea that lasts after you stop playing, take a break and consult a healthcare professional if symptoms persist. It’s also important to stay hydrated and play in a comfortable position. If you are prone to motion sickness, consider playing in shorter sessions and gradually increase your tolerance. The Steam Deck’s portability means you might play in different environments, so be aware that a moving car or train can worsen symptoms.

Alternatives to Frame Motion Smoothing

If you cannot tolerate frame motion smoothing, there are alternatives to achieve smooth gameplay:

• Play games that run at high frame rates: Choose games that can run at 60fps or higher on the Steam Deck. These won’t need interpolation to look smooth.
• Use the Steam Deck’s built-in FSR (FidelityFX Super Resolution): FSR can boost performance by rendering at a lower resolution and upscaling, giving you higher frame rates without the need for motion smoothing.
• Adjust the game’s internal resolution: Lowering the resolution can significantly increase frame rate, making the game feel smoother natively.
• Use a wired connection for streaming: If you’re using Steam Remote Play, a stable wired connection can reduce latency and frame drops, which might help with motion sickness.

Frequently Asked Questions

Will turning off frame motion smoothing reduce my game’s quality? It might make the motion look less smooth, but it will remove the artificial frames that can cause sickness. The visual quality in terms of resolution and detail is unaffected.

Can I use frame motion smoothing on all games? No, it depends on the game’s engine and how it handles frame pacing. Some games may not support it, or it may cause more issues than it solves.

Is there a way to test if I’m sensitive to frame motion smoothing? You can try enabling it for a few minutes in a game with fast movement. If you start feeling dizzy or uncomfortable, you’re likely sensitive. Turn it off immediately and see if the symptoms subside.

Does the Steam Deck OLED version have different motion smoothing? The OLED model has a different screen, but the frame motion smoothing feature works similarly. The same settings and tips apply.

Can I get motion sickness from the Steam Deck even without frame motion smoothing? Yes, low frame rates, motion blur, and playing in a moving environment can all cause motion sickness. The tips in this guide apply to those situations as well.

How long does it take to adjust to frame motion smoothing? Some people adapt over time, but it’s not guaranteed. If you don’t feel better after a few sessions, it’s best to leave the feature off.
