Adjust game resolution in Zwift
If you feel like your computer is not keeping up with the demands of the Zwift game, or if you're not able to stay with the group even when pedaling, try changing the resolution settings of the game.
To change resolution settings:
From the Home Screen, select your initials at the top right, then select My settings ((if you've started an activity, select Menu, then Settings at the bottom right of the in-game menu).
Select My Settings
Select Preferences, Sound and Display, or Controls to adjust your settings.
When you're happy with your settings, select OK.
