Did my first ride yesterday, some comments:
* I ran out of harddrive space during install and Zwift crashed before fully done. I would expect it to fail gracefully. (After some clean up it installed nicely on the second try.) I have logs if you are interested, where to send?
* The FPS is really low. I estimate somewhere between 4-7 frames/second. I have a barebone Intel H61-desktop computer so I expect it to be slow with graphics, but as an example I get 38-40 frames/second with Quake Live. CPU and Network load was minimal during the ride so graphics was the bottleneck.
* Somewhere to put my body weight in and that the virtual speed depends not only on pure watts but watt/kg(+air-resistance).
