I’d check if you are running out of memory. How much is installed? You’re the second person I’ve heard from who has not had success from the driver upgrade (among dozens). The other guy had 8GB installed but no option to add more in his laptop, and these Ryzen systems with integrated graphics steal system memory for the GPU, so with 8GB installed they have less than the minimum recommended for Zwift.
I would also disable the video screenshots feature in Zwift settings.
Aside from that you could send a log file to support@zwift.com to see if there is some other issue causing the crash that they can identify.
That might be the problem, my laptop has got 8GB RAM in total with 5,86GB available.
How can I see if I can add more to my laptop?
Even though I think this is the problem I dont understand why it is, as my laptop has runned Zwift without any problems for 18 months. I don’t know a lot of digital stuff
Yes something changed recently for sure. It may be that some systems that barely got by with that amount of RAM have tipped over a line and are now failing, or perhaps the memory leaks that are helped by this driver update don’t completely solve the problem.
To understand the possible upgrades you would need to know the make/model of the laptop. A screenshot of the system tab in the Windows DXDIAG utility would answer that if you want me to look it up, or you could take it to a PC shop and ask them what your options are. Memory is pretty cheap and most of the expense would be labor if you pay someone to do it. Some laptops are really easy to upgrade and can be done at home with a screwdriver, but some are a real pain to open up.
It looks like that is an IdeaPad 3 17ALC6. That 17ALC6 model number is probably printed on a label on the bottom of the laptop. If that’s correct it has 4GB soldered on the motherboard and one slot for a RAM upgrade, which currently has a 4GB memory module for a total of 8GB. The 4GB module could be replaced with either an 8GB or 16GB memory module for a total of either 12GB or 20GB RAM. Crucial says the memory is DDR4 3200.
It looks like the upgrade process involves removing 10 screws and then carefully prying the plastic bottom off the laptop to expose the memory slot. I usually search YouTube for a video of the upgrade process. For example you could search YouTube for ideapad 3 17alc6 ram upgrade and you’ll get various results for similar models.
I can’t guarantee this will resolve the crashing issues but it would be a nice upgrade anyway.
I’m having the same issue and talking to tier 3 now.
They’re aware of an issue with AMD machines and my gut tells me it’s a memory leak. If you watch task manager, you’ll likely see the app hard lock around the 93-95% RAM utilization. The app will start at whatever RAM usage percentage (75%’ish in my case) but will constantly creep up forever until it crashes. It’s easily reproducible on my end.
Having the same issue for the last few weeks too. After around 30 minutes it starts with the riders disappear and its just bikes and helmets but tthen it freezes up and i can’t save the ride. I’ve added ram and swapped the gpu for a Gtx 750 but still the same issue.Anyone any suggestions?
Same issue here. I bought a new lap top this summer AMD Ryzen 5 - 7530u with 8gb soldered in with no expansion slot. Worked great till about 2 weeks ago, zwift froze up about 2/3s in Peak performance loop, about an hour 20 in or so. Then today froze up with 2.6k left on triple twist. I’ll make sure drivers are updated and disable video screen shots.
Quick follow up. I checked and my drivers are up to date, and I already had disabled video screen shots. I changed the video from high to medium. Hopefully that helps. This is pretty annoying; I assume Zwift knows most of their users are not IT people. I purchased a new laptop this summer, I looked at Zwift requirements and purchased one that met them without spending more than needed.
Riders disappearing while bikes remain on screen typically means you have run out of CPU for some reason. That’s not necessarily a video driver or GPU problem.
Will check my CPU usage next session so. I’m using a xeon e3-1241 CPU , 20gb ram and gtx 750 graphics card. Was working well up until a few weeks ago. Problem seems to happen more with crowding on routes.
Zwift did say this (linked below) about crashes on Nvidia systems recently but I’m kind of doubtful it’s what you are dealing with. On an Nvidia system you should be safe with the driver provided by Microsoft, no need to update it with anything newer from Nvidia. You should also make sure you’re not burdening the CPU with anything other than Zwift, like Sauce or OBS, while you are troubleshooting this. You could upload logs to zwiftalizer.com and post results here or on the ZPCMR Facebook group.
Hi, in the last week or so i have had zwift crashing between 40-60 mins every ride, it seems to be since the last update, I’m running a laptop with windows 11, amd system, everything is upto date, i’ve tried all suggestions on various threads, deleted old files so i have plenty of memory etc, turned off video snapshot recording, its getting very annoying now trying to follow my training program, any ideas?
Just to update from my previous posts. I updated to the latest nvidia driver and it ran smooth today for 2 hours.Seems the previous nvidia driver update in October had some issues with zwift latest update, as described in the link Paul shared. Thanks for the help.
I just zwifted again. Last week I upgraded my laptop from 4GB memory module to 8GB, so in total 12GB RAM. Also I updated the driver.
After 45 minutes Zwift crashed again, same problem as two weeks ago. Anyone knows what might cause the problem?
Oops. I’m having the same issue, on a Ryzen 5, 5xxx series. 12Gb of RAM. Been running fine up until a few weeks ago. Updated drivers.
Normally I could run Zwift, after rebooting, no companion app, empty route/world and it would be ok for a 60-90 minute ride (haven’t gone farther). Today rode in Watopia, no app, after rebooting… locked in 54 minutes.
I have been running some tests on my Ryzen Laptop with integrated graphics. 8 GB of RAM, from those 2 are reserved for the GPU.
576p - Crash after 1:55 h
1080 - Crash after 1:15 h; 55 min; 50 min
4k - Crash after 2:25 h (weirdly, has obviously the lowest FPS)
In the task manager you can watch the RAM cluttering up, starting at maybe 80% and then going up to 98%.
8 more GB of RAM will be installed today, hopefuly that will resolve the problem.
I will keep you posted.
Also: Why is there still no option to finish rides that have not been ended by the rider within a reasonable grace period to reboot the PC, or the trainer, or fix the internet connection?
It is a topic that comes up regularly in the feature request forum:
/t/autosave-to-finish-rides-after-crashes-or-disconnects/639940
/t/ability-to-rejoin-a-ride-after-disconnect/624037
/t/resuming-a-workout-after-computer-crash/240870
Installed the latest update (1.79) now I can report that it crashes after 90min… reliably.
It managed 2-2.5h with 1.78.
Luckally I have managed to convince 5 people that asked me about zwift over the past weeks to try something else… I am stuck with yearly subsciption…
