I ran Zwift in my old core duo 2007 iMac the other day OS10.11 ( the latest available)
After it had upgraded ( slowly) to the latest version of Zwift
I did a lap of London ( where recently it always seems to be raining) and it was still raining I the waster tube tunnel near tower bridge.
Generally this computer runs applications as fast as my iPhone and iPad. Why does Zwift take so long to load on my iMac, where its almost instant on the tablet and phone?
I know the graphic card is low resolution and low frame rate, but why the slowness before the game even starts?
