I gave mywhoosh a go last night since zwift decided to act up and give me "no signal" for my trainer and sensors despite trying everything I could think of to get it to work. Mywhoosh worked. I only used it for an hour and just to do a zone 2 ERG mode ride so I don't have a lot to say about it yet. I do think I'll end my zwift subscription next month though and give mywhoosh a go. I don't give a poo about group rides or any of the other social aspects of zwift, I just need something to run my trainer in ERG mode while doing training rides and it looks like mywhoosh will do that fine and well FREE. I'm running it on my old gaming laptop with a nvidia 2060 and that seems to handle it fine but from the youtubes I've watched it is rather GPU hungry.
