Forza Motorsport 6 makes its way to PC in the form of an Apex edition. Direct X 12 and 4k support are included if you have a PC powerful enough to run it. The great news is it is now in Open Beta so you can download it and try it out. It weighs in at 18gb. You can download it from the Windows Store.
I’ll provide my thoughts over the next couple of days (downloading now). If you download the Forza Hub Windows Store app as well you’ll get a free car added to the Apex Garage (2012 Nissan GTR Black).
