It looks like this problem has been fixed. I just rode Zwift with the GPU enabled and it worked great! Not that much difference in graphics quality between the integrated GPU and the nVidia GPU though.
I’m in the market to replace my 5 y old dell xps lap top w i7 and geforce gt 435m w a 2-in-1 (as my old ipad 2 is slowly dieing). I’m considering a surface book. Is it worth it to pay more to get the model w the dGPU vs the lower end one w the onboard intel hd 520 gpu, as far as zwift performance goes? I looked at the zwift log file but can’t find how many fps i’m getting on my current rig
also considering getting a SP4, but currently when on zwift one usb is used by my computrainer and the other by my garmin dongle… whats the work around if SP4 has only one USB port? Will a USB hub work?
