only a few rides in and zwift has been working great - no crashes, no dropped sensors.
I’m running on a i7 laptop with 16gb, and 2GB NVIDIA GeForce GT 640M Graphics card - mirrored out to a big TV. Due to the card being fairly low end I suspect I’m running with the lowest quality graphics options - but still works fine.
The only regular video glitch I see is when I’m passed by other (human) riders they occasionally zigzag across to the other lane at high speed - it all returns to normal in around 1 second.
I also see some other video glitch on the “close the gap” graphic - it momentarily leaves some kind of artefact around my riders head hight.
