It is recommended that players do the following if they want to achieve high FPS while playing Genshin Impact on their device:
1. Turn on GT mode in your device.
2. Pause the game to summon the Paimon Menu.
3. Select the 'Graphics' option.
4. Set the 'FPS' option. Adjust it to the user's preference.
5. Set the 'Graphics Quality' option. Adjust it to the user's preference. (The lower the quality, the easier it is to get a better FPS)
Tips:
1. There is a bar at the top that reads 'Smooth', which is to the right of 'Current Performance Load'. Ideally, the green bar should be as small as possible.
2. Some graphics settings will not take effect until you restart the game.
