Game Update 1.26 [June 2022]

I raised your question with the team, and I was told that not all bodies of water will trigger reflections to reduce runtime loads. That particular lake may have that effect intentionally.

Thanks for the feedback. This is interesting, since it did work three out of four times. :thinking: One can only assume that it was due to the time of day in-game and how the sun was shining that there wasn’t a reflection.

No idea about this issue ? Thx


Your crash logs and your game logs may provide some clues to see what’s happening on your machine. Please go to and let us know that you want to email us the crash logs, and this will get you to one of my colleagues who’s good at reading those logs.

These need to be emailed because we don’t allow uploads of text files on the forum due to malware risks.

it sounds like you may know this already, but you can find game logs using these instructions and logs for crashes that occurred in the past 24 hours by following these steps:

Game crashed for me for the first time in years tonight, all because my internet connection dropped out on the home screen (I think). Loaded into London which took ages, frame rate was abysmal and repeatedly locked up fully for seconds at a time. Avatar was flickering, then it just died to desktop. Log file shows hundreds of curl errors where the hostname couldn’t be reached. Nothing at all in Event Viewer or Reliability History, the game just ended itself.

Starting to suspect the internet connection watchdog and/or an inconsistent connection to the subdomain above might be what causes the stuttering I’ve been noticing.

PS: on the basis of the errors, every single user account has its own URL at /api/profiles/<youruserid>/in-game-fields/. That seems like a lot of folders.

They won’t be actual folders. It’s an API call where the user id will be used to look up whatever in a database or some other data structure.

Ah okay, can’t say I know what I’m on about with web stuff. Not unusual.

Power curve still has issues. New power records in the power curve for several areas don’t meet up with the best power curve.

Hi @shooj !
Thank for helping. Actually I did a complete uninstall / install of Zwift. Seems to be better (first short ride about 30mn OK)… Wait and see :slight_smile:

I have a MacBook Pro with a Gen 10 Intel i5 processor. I was reading through the latest update to see if there had been any fix to the issue, it seems, a lot of zwifters with this processor have been having since one of the previous updates… has there been any specific attention paid to this issue? Before, I would be able to ride for hours without an issue, but now my computer will restart randomly after opening Zwift. I have seen it where my MacBook will restart before I’m even fully logged in and ready to ride and other times when I’m 20 minutes from finishing a workout. Would love to see this issue be fixed! :slight_smile: If there is amen thing I need to do, please let me know! Thanks!!

Buenas tengo problema para abrir la app de Zwift a traves de un proxy marca ZSCALER, me puede ayudar a ver cual es el problema, ya logro que haga login pero no carga toda la aplicacion bien.

I wonder if your mac might be overheating. My wife’s older MacBook Pro gets super hot running Zwift because it is pretty demanding of the CPU. If I were in your situation, I would quit all other applications and use Activity Monitor to see if anything other than Zwift is on the CPU, prune startup items if necessary, reboot the computer before running Zwift, make sure the vents and fan are clear of dust and pet hair, and if all else fails I would aim a fan at the computer and set it on a bag of ice to rule out overheating. A completely failed CPU fan can also cause a problem like this when a demanding app is running but not otherwise.

:joy: :cold_face: (8 chars)

I will try this on my next ride and see how it goes! Maybe not the bag of ice part, but I know they make platforms for computers with fans underneath to help keep cool the computer above it! :slight_smile: I’ll try it and report back, thank you!

One other thought: reset the system management controller (SMC)

One more: try running the laptop on battery power for the duration of the ride. Afaik the stupid computer-frying CPU overclock settings for Macbooks are only enabled when running on mains power.


This might deserve its own thread by now but I had a few more ideas to try. I promise to shut up now.

  • Run Apple Diagnostics to check the hardware. You could also use MemTest86 to check memory more thoroughly, but it can take a LONG time (days) depending on the test suite and amount of RAM
  • In Zwift settings, set Game Resolution to something lower
  • In Zwift settings, set Laptop Battery Saver at some level other than Max Speed

If all else fails…



Hey everyone - we’re always looking for ways to improve our security practices to protect our users’ data. With Zwift game version 1.26.2, we upgraded some security measures. If your home network setup is very strict, it’s possible that the firewall settings on your Zwifting computer and/or router may have to be reconfigured in order to connect to Zwift.

Your firewall should allow incoming and outgoing traffic on:
TCP ports 443, 3023 and 3025.
UDP ports 3022 and 3024.
