As a boot camp user (only for PC gaming) for the past 3 years, I'm inclined to agree, actually. I just upgraded the boot camp installation on my retina iMac to Windows 10, and it went off without a hitch except for the AMD drivers, which aren't supported. Except AMD doesn't ship the drivers for it, Apple does. So I have to wait for Apple to ship Win10 compatible drivers for AMD's card, and who knows how long that'll take. Meanwhile this is my primary gaming box (yes, it actually is quite a nice machine GPU-wise) so I guess I can say goodbye to PC gaming until Apple is gracious enough to provide me with an updated driver. (The last driver they shipped was in December 2014, it's been total silence since then. Who knows if they'll ever update it? Maybe El Capitan will have new drivers as part of an updated Boot Camp Assistant? Do they even care?)
