Hello, @JinThomson! In general, the higher graphic settings option will provide enhanced visual effects. For instance, graphical elements on HDR will be much enhanced and more visually pleasing in comparison to smooth graphic settings. Moreover, some special effects look better in higher graphic settings. However, you should note that higher graphic settings might require your device to perform more. As such, the 90 FPS option is only available while using the Smooth graphic settings option.
