Significant Lag with Resistance

Hi guys

I am using a Tacx Flux S via Bluetooth on a Mac and every second ride or so I make in Zwift I experience terrible lag in the resistance change of my trainer. We’re talking about 2-3 Minutes of lag between what happens on screen and what the trainer does. Other times it works perfectly fine. I’m running the newest firmware versions of everything. Trainer is calibrated.

Is this a known issue? Is it a software-related problem or is something wrong with my trainer?

Thanks for the help.

Hi @Marco_Fassler

Can you drop your log file into Zwiftalizer.com and look for dropouts and low frame rate (FPS)

Hi, thanks for your suggestion. Since I have no experience with this, here are the screenshots:

Can you tell me what you see?

Looking at the log it does not look like dropouts. And your frame rate is ok but I would suggest dropping the resolution to basic and see if that help.

In big group rides your FPS may go into the low teens and that is not good.

Ok, I’m going to try that. Thanks for the suggestion.
