What frames per second should developers aim for in VR games to help combat nausea?

In virtual reality (VR) games, achieving a frame rate of 90 frames per second (FPS) is crucial for providing a smooth and immersive experience for players. This higher frame rate helps to create a more fluid motion in the game, which is essential for maintaining the user's sense of presence within the virtual environment.

At lower frame rates, such as 30 FPS, motion can become choppy and laggy, leading to a disjointed visual experience that can confuse the brain and contribute to motion sickness or nausea. VR relies heavily on quick and accurate feedback to the user’s motion; therefore, a minimum of 90 FPS is often recommended to ensure that the visual experience closely aligns with the user's real-world movements. This high frame rate reduces latency, minimizes blur, and enhances the overall realism, making it easier for players to feel comfortable while in the VR environment.

Frame rates of 60 FPS and even 120 FPS may also be beneficial in certain contexts, but 90 FPS is considered the industry standard for a balance of performance and comfort, especially when aiming to reduce the risk of nausea among players.
