Frequently Asked Questions
Why is my FPS locked at 60?
Most browsers lock the rendering frame rate to match your display monitor's refresh rate (V-Sync) to prevent screen tearing.
How can I test higher refresh rates?
Ensure hardware acceleration is enabled in your browser settings, and that your display settings in your OS are set to your monitor's maximum refresh rate.
