I’m not sure it is a problem with your configuration. In the past two weeks I have suffered multiple screen freezes and app crashes making zwift unusable. Previously I have been Zwift for over a year with no real issues so I am not sure what has changed.

I only use Zwift for structured workouts so having an app that constantly crashes make it a tad useless

The 560M is not a powerful GPU, but you may not even be using it, and instead using the built-in Intel GPU for rendering Zwift.

Go into your NVIDIA Settings (sitting in your System Tray) and make sure your PhysX is set to your NVIDIA GPU, and not your onboard Intel GPU. Also make sure vSync is disabled, or you will cap your FPS at 30fps.

This KB I wrote should help further:
