Zwift intermittent shut downs


I have been having random shut downs lately (software simply closes itself back to my desktop with no error message showing).

This started happening while just creating and modifying custom workouts, but today it happened half way through a session.

I’m running a win 10 PC with at least the minimum requirements, everything is up to date. I’m using a TACX ANT+ aerial and a wired internet connection with good UL/DL bandwidths.

Is there a way to attach my logs for someone to have a look at through zwiftalizer?

many thanks

we will need more pc specifications.

But you can look at your windows crash logs, it might be a graphics driver or intel gen 10 or 11 on board graphics


PC specs-

windows 10
8GB ram
AMS radeon R5 310 GPU
I3 4160 3.6GHZ processor
over 400GB available space

Ive checked the windows crash logs and can see the following around the time zwift shut down-

'Faulting application name: ZwiftApp.exe, version:, time stamp: 0x608c37f7
Faulting module name: ntdll.dll, version: 10.0.19041.928, time stamp: 0x9bed63d6

And also-

ATI EEU maximum number of session has been surpassed

That is an extremely slow graphics card I’m afraid. In fact I’m almost certain you’d get better results from the integrated graphics on your CPU and it may be more stable too. Worth a go.

Stick a log file into and post the results, I’ll be able to tell you.

Hi Dave,

Not sure how to attached the results?

Graphics profile

Your graphics profile (level of realism and detail) is Basic . The levels are Basic, Medium, High and Ultra. Integrated GPUs, iOS and Apple TV devices use a Basic profile. The Medium and High profiles use higher polygon count models, higher resolution textures, and more sophisticated shadow and lighting effects. The Ultra profile adds even higher polygon count models. Graphics profile is automatically set by the game engine according to the capabilities of your graphics processing unit (GPU). You can not set it yourself. You do not necessarily need to be running the Ultra or 4K resolutions to get the Ultra profile. An Nvidia GTX 960 or higher will get the Ultra profile at High (1080) resolution.

Graphics resolution

The highest resolution detected for this activity was 1080 full high definition (FHD), which is the same as full HD television. This is the middle setting. This is the number of pixels rendered in the vertical axis. It is independent of the resolution of your display. The options are 576 (standard definition - SD), 720 (high definition - HD), High (1080 - full high definition - FHD), Ultra (1440 - wide quad high definition - WQHD - 4x as many pixels as 720 HD), and 4K UHD (2160 - ultra high definition - 4x as many pixels as 1080 FHD). You can change the graphics resolution at any time in the game settings. However, a high end discrete GPU is necessary to unlock the 1440 Ultra and 4K resolution options.

1440 and 4K Ultra capable GPUs

Nvidia GeForce GTX 1650 Super

Assuming you can’t attach a screenshot?

Anyway looks like you’re on 1080p resolution, Basic profile and getting 9fps average. In which case you’d be much better off on your CPU’s integrated graphics. It won’t look any different, but will run at 20-30fps and be a far better experience. Or just buy a GT 1030. :wink:

Thanks for the input Dave, With the 1030 or similar, would i need to upgrade anything else with that spec of PC, more ram for example?

Nope, as it happens your specs are spot on even if you wanted to go right up to 4K and Ultra profile (that’s if your PC can physically take a full size graphics card and upgraded power supply), you’d have to spend a lot of money to substantially beat your current CPU and more RAM doesn’t do anything. An SSD is always a nice upgrade but not necessary.

Biggest problem right now is supply of such graphics cards, and therefore the costs. It’s ridiculous. The GT 1030 is mostly unaffected though, and would take you to Medium profile at 60fps (solo rides) which is a huge step up. It’s available in low profile too, so would be a straight swap for what you have now.
