Hi. After the latest updates i’m trying to finish the tour of watoria and the stage 5 - Deca Dash. 2 times (yesterday - today) exactly after 1 hour of training the zwift is getting slow and then is crashing.
System: windows 10 pro 22H2
Thanks
What’s the CPU, GPU, amount of RAM in the PC?
I never had issues before and for this reason i opened a topic.
Cpu: athlon x4 860k 3.7ghz
Ram: 8gb
Gpu: Amd radeon Hd 6670 2gb
Several people have reported that the updated Radeon driver from the AMD website helps with this issue. Try that and let me know if it helps you. Most of those people were using integrated Radeon graphics so I’m unsure if it will.
Ok thanks I will try but is a bit old i don’t think i will find any update. It looks a ram issue for me. The app starts with 2gb ram and at the end needs 5gb+.
Also it do it at the same hour when 24000+ users are online.
I did the update. I will try on weekend and i will post the results.
Thanks again
Hi. I tested today at the same time and i finished the same route without issues. It seems that the update did the work. The ram was continuously at 1,7 - 2gb. Online user was about 14000.

I had a similar issue today after updating (yesterday I believe) to the latest Zwift version. After almost 81 minutes into a workout, the Zwift window froze completely, ultimately had to terminate Zwift using the task manager. It somehow had saved the workout in a .fit file. I have never had this before. This is on a relatively new Windows 10 desktop with 8 Gb of memory and an AMD Radeon RX 550 graphics card that I have been running Zwift for several years on without any issue.
When was this driver updated? Because I installed this desktop just a few weeks ago with the then latest drivers from the AMD site.
Good question, I don’t know. You can check the driver version (eg, in DXDIAG) and then check it again after installing the latest.
Note that some people who have installed the latest driver are still reporting crashes, but many have been helped by doing it.
