Zwift crashes when saving workout on Windows 10


(Matt) #1

Joined Zwift yesterday. Running Windows 10 with 16gb RAM. The program seems very buggy, isn’t very smooth and crashes when trying to save each of my workouts the past two days. Not very happy during this trial/

Please post the full specs of your PC and which version number of Windows 10 you are on.

Are you running Zwift in full screen or Windowed Mode?
What graphic setting are you using within

Just an FYI the program closes when saving rides/runs.


(Matt) #5

I’ve tried both with the same result, when I click “End Ride” the ride’s summary screen minimizes then Windows says “(Not Responding” and is frozen for 60 seconds or so then crashes/closes.

What do you mean by “graphic setting”?


(Paul Allen (Watopia Wayfinder)) #6

When in Zwift go to Settings and what do you have the resolution set to?

Also, do this work around to see if it improves the closing of Zwift when you are saving: [Workaround] Zwift not saving rides/creating folders

I am a firm believer that if you are running Windows 10 that you should also be running an SSD.
