My Zwift has been jerky for a couple of days.
It recognizes Watts, cadence, etc at first. Then I ride for a few seconds only
and then my avatar stops.
Have not been able to ride for the past couple of days.
I downloaded the app again, restarted my Mac, etc…but problem persists.
It’s a Tacx Neo connected via bluetooth to an IMac.
I’ve been doing everything as always. Today I decided to reinstall the Zwift App and restart the iMac. At the g]beginning I thought it solved the problem as the Zwift app recognized everything, including watts & cadence and it seemed fluid, but my ride only lasted 40 seconds. Then my avatar stopped and as others riders went by, it became jerky again.
I don’t know much about Macs but what you are describing sounds like some sort of CPU throttling activity happening. As if your Mac is heating up in the 40 or so seconds you are running Zwift and to protect itself the Mac is throttling the CPU. Is this something you can check?
Bt shouldn’t suffer dropouts at that range unless it’s caused by interference.
To experiment you could purchase an ant+ dongle to see if that too suffers.
Is your firmware up to date on the Neo? There have been issues with BT dropouts on the Neo which were addressed in a firmware update but a small number of users still report issues.
