Game Randomly Crashing During Workouts

Bugs and Support
1

Hello,

I’m experiencing an issue where Zwift randomly crashes during workouts. Sometimes the game runs fine for 40 minutes or more, but other times it closes unexpectedly after just 10 minutes. There’s no error message—Zwift simply shuts down.

I’ve tried connecting my trainer (Magene T600) using both the Zwift Companion app and Bluetooth directly on my PC, but the crashes happen in both cases.

Here’s my setup:

  • Windows 10
  • Processor: Intel(R) i7-11700K
  • RAM: 32 GB
  • GPU: NVIDIA GeForce RTX 3050 (8 GB VRAM)
  • Trainer: Magene T600

I’ve noticed some errors in the log file, such as missing WAD files (e.g., gearing.wad) and issues loading textures and shaders.

The crashes are really frustrating and disrupt my training routine. Any advice on how to fix this would be greatly appreciated.

Thank you in advance!

I updated Windows to 11, updated Zwift, let’s see if this helps.

Nice PC, more than adequate for Zwift.

Some standard things to do:

  1. Use the Nvidia driver that comes from Microsoft. There is no need to experiment with newer versions.
  2. Disable Microsoft OneDrive
  3. Disable any anti-virus software other than Microsoft Defender
  4. Reinstall Zwift using these instructions to clean out the old installation. Re-Installing Zwift

I’m using the official driver from Nvidia, I don’t use OneDrive, although I don’t understand how that could affect it. The only antivirus is Defender, and it’s partially disabled. Considering that I installed a new system, there’s no point in reinstalling Zwift anymore. )))

There have been crashes reported from people using recent Nvidia drivers. There is no benefit to using a recent one from Nvidia for running Zwift. I don’t know if this is the problem you’re running into. I suggest using the driver delivered by Microsoft. My system (GTX 970) is completely stable with an old driver.

I edit videos in DaVinci Resolve, and the latest version wouldn’t start without a driver update.

In any case, it’s highly likely that this is a flaw in Zwift, as the developer could catch and handle the error to prevent losing workout progress. A full application crash is clearly some kind of unaccounted-for exception.

I hope the developers will figure out this issue, and everything will start working stably without any hassle.

I think you are right about that. If you test the game with an older driver you might find that is true.

The main difficulty in finding and testing such intermittent bugs is that the game sometimes works perfectly for 40 minutes, but other times crashes after just 10 minutes. (

I checked my driver version in dxdiag and it’s 32.0.15.6094 from August. Zero crashes on that.

Hi Alejandro,

Thank you for following up! Yes, I was contacted for clarification, but by that time, I had already reinstalled Windows to version 11, updated Zwift to the latest version, and installed the most recent graphics card driver (even though my previous driver was relatively up-to-date, it wasn’t the latest version).

Since then, I’ve completed three rides without any crashes so far.

Best regards,
Aleksandr
