Righto - just to clarify, your ping is 15 milliseconds and not seconds mentioned above, right? 15ms isnt exactly fast, but its not terrible. But you mention above your ping can get up to 35/40ms. I would suggest that is starting to push the limits.
I’ll post a pic of one of your Zwiftalizer view of logs here for others but some observations (and bear in mind I am not a pc person):
Your screen FPS drops to a really low number but is often OK. Something is being stressed periodically and may be consistent with the FPS issues some of us have been having for the past weeks since a Nov update.
You are getting quite a high 2-4% ANT failure rate is unlikely to be helping.
Networks - your network is not great and the error condition being picked up and mentioned in the logs is interesting Couldn’t resolve host name’ for: GET https://us-or-rly101.zwift.com/api/profiles? [snipped]
So this tells me Zwift is trying to get some data, likely your workout data, from a host but because it cant resolve the name, it cant get the data. This is in your Log (old 1). You could also be using a really slow DNS server and its not responding quickly enough for Zwift’s liking. It would be nice if Zwift had a FAQ covering log msg interpretation!
I’m guessing, with the recent updates where played around with video performance (to our detriment and causing a lot of lower FPS issues for some folks) will not have helped you at all. But with your network not being very clean, I think those events are causing the issue of causing Zwift to get confused with timestamps.
I’d suggest you log a support ticket with zwift with a focus on asking what the likely outcome of that error in your logs is. Many would suggest you get your network sorted too. Powerline if you cant run an ethernet cable seems popular for people. Also, you can x your fingers and hope Zwift fix up there current video problem. Also, some people here might be able to help you tune your vid card/pc a bit. Finally, if you did a workout in your house with current setup, would you get the issue? If not (which I suspect you wont), then that will really determine what you should do next (hardwire your network to your cave.).
