@Anton_Moiseenko Great to hear, thank you for letting us know!
My Surface Win11 on AMD 64 started crashing so badly on Fri Jan 17 2025 after only 15 minutes each time, that I uninstalled it. First, I would get just an object or two pixelating (a single tree or side of a building), then the entire background or foreground, then the workout would freeze. All graphics options were turned off in Settings, my instance was running fullscreen, not in a window. Three tries to make it through the same course, and I had to stop. Maybe I’ll try again after the next version is released.
Which model of Surface do you have? Did you mean to say ARM64? Because those systems are not supported by Zwift.

I had updated to the latest version(at the time) but I was/still am getting the app crashing, but only when I save at the end of the session. I haven’t risked going back to allowing screenshots to be automatically taken whilst using Zwift, so thankfully it doesn’t crash mid session, but I still have to close the app via the Windows task manager.
I did run my laptop with 8gb of memory, then updated it to 24gb of memory in the hope that this may solve the issue but it does seem to always happen when saving the session to exist.
Any thoughts on what to try next?

Really pleased to confirm that the fix has worked for me - I ran the update and have been doing workouts for the last couple of weeks and I’ve not had a freeze since. Many many thanks! Appreciate the free month as well

@evan-zwift After several tests, I can confirm that the crash issue has been resolved on both of my PCs. However, unfortunately, Zwift still crashes during the saving process. This happens consistently on both of my computers, both of which have AMD graphics cards. Fortunately, the activity is still saved, but Zwift has to be closed via Task Manager.
It would be great if this issue could also be addressed.
That being said, it’s fantastic that we’ve finally made a big step forward and that no one had to buy new hardware. As a small bonus, it would be nice if the promised free month, as announced via email, actually gets credited.
Thanks for the continued improvements! 
Hi @Tobi_Frtz_R2, thanks for the update and for the report of the additional issue. We’re investigating this.
Hey there so I also have crashing issues on my ROG Zephyrus AMD Ryzen 9 4000 with Nvidia GEFORCE RTX. It looks like i am running zwift version 1.83.2 about 5 mins into my ride the screen freezes then app closes. I made sure i have all window updates. Should I try turning off Avast premium security even though I hade zwift as a acceptable app? please help this is very aggravating. My iwfe went to Rouvy and I might have to follow. Thanks Scott James
Hi @Scott_James, welcome to the forums and sorry to hear about the issue. You shouldn’t need to turn off security software but it’s difficult to say whether or not that could be contributing to the issue.
If you haven’t already, could you please try doing a clean uninstall/reinstall of Zwift? That would help rule out many issues in the local installation.
Hi Evan, Well I read on another post about updating the grphics card on my laptop. So I ran a test last night. I opened the game as if I was going to ride and jsut sat there to see if it would crash…sure enough the app closed. I then went to nvidia webiste and downloaded an updated driver and repeated the test. The app stayed on for 31 mins before I just closed it. So I think this has fixed it but will know more tonight when I try it. This was the driver that added and it mentions fixing flickering on gaming apps and such so maybe it has helped the Zwift app. It was updating the Geforce RTX grphics cards. The update was released on 1/30/2025. The general notes on this update is as follows: Fixed Gaming Bugs
- Certain G-SYNC Compatible monitors may display flickering when game FPS drops below 60FPS [5003305]
- [G-SYNC] Indiana Jones and the Great Circle may display micro-stutters when Vertical Sync is disabled [5015165]
- Improved stability for Ubisoft games using the Snowdrop engine [4914325]
Fixed General Bugs
- [Evernote/QQ/Asus Armoury Crate] displays higher than normal CPU usage [4730911]
- Motion blur renders incorrectly in some more cases in Blender Cycles [4912221]
- [KeyShot2024] TDR on loading the scene Camera Keyframe Animation [4909719]
I will update later for my results. If still crashes I will try the uninstall then.
Hi @evan-zwift I can confirm after the graphics driver update it is no longer crashing.

Thank you @Scott_James for following up with those findings! I’m really glad to hear that the Nvidia graphics driver update resolved the issue.
Looks like a memory leak is back in 1.85.
RAM maxed out at 95%, app hard locked, exact same symptoms as before.
I just upgraded. In my case the game is using A LOT more memory than before:
According to my previous post in this thread, it was in the range of 2.3GB in version 1.81.2.
“But” I was monitoring the numbers and it’s stable. In my case it allocated all that memory at the start of the ride and then it remained there. It’s basically allocating 2 extra GB compared to previous version. And as the extra memory requirement goes straight into the working area, it means higher risk of hyperpaging situations on smaller systems.
Until October I was running zwift with only 4GB with no problem. Then I increased the memory to 8GB to mitigate the issue. I guess after this update my old configuration would not work at all.
But I guess this might or might not be related to be running with AMD GPUs?
Even after the latest update and a fresh installation, Zwift still freezes when saving an activity. While the activity itself is saved and uploaded, the game remains stuck, requiring a manual shutdown. This is incredibly frustrating and shouldn’t be a long-term issue.
Additionally, Drops are not being saved and are lost every time this happens. I estimate I’ve already lost around 500,000 Drops due to this bug.
On another note, I have yet to hear anything regarding the promised free month. It’s starting to feel like something was announced but not actually implemented.
Would appreciate some clarity on both issues!
I also noticed this on a PC with 8 GB of RAM and GeForce 1050.
Hi folks, thank you for the reports, we are looking into it.
Hi all,
We just released Zwift Game version 1.85.2 for all Zwifters on Windows - please update when you are able and let us know if you continue to observe any issues.

Memory usage is back to 3.7 GB after loading Watopia, same as version 1.84, while version 1.85 was using 5 GB.
