I’m experiencing about a 3 second delay between the gradient I can see on the route (including the percentage shown in the map at the top right corner) and what I feel from the trainer.
To explain a little more, the gradients feel right they are just delayed by about 3 seconds. For example, on Downton Dolphin on the ‘Prime’ climb, when I first hit the bottom of the climb I don’t feel any increase in trainer resistance till I’m 3 secs in to it. When the climb has finished and goes back to flat, I still feel the resistance for another 3 seconds.
The trainer difficulty setting in the Zwift settings menu is set at default 50% if that makes a difference.
Windows 10 (64 bit)
Intel i3-4130 @ 3.40ghz
NVIDIA GTX 960 2GB
50mbps Ethernet Wired Fibre Broadband
Garmin ANT+ Dongle with 2m USB shielded extension cable (placed under bottom bracket)
Saris H3 Trainer (Ant+)
iPhone companion app (12 Pro / iOS14.7.1)
Taope Heart Rate Monitor (Ant+)
32” Celcus TV @ 1080p via HDMI (60hz)
My previous setup used the Zwift iOS game app on my phone, connecting everything via Bluetooth. There was never any gradient lag on this setup with the same trainer, so I guess it’s unlikely it’s a trainer issue.
Any ideas please?
