So, September is rapidly approaching, and with it should come Apple's latest and greatest OS X upgrade. We know the basics of Metal (Apple's new graphics API), but specifics and particulars are shrouded beneath layers and layers of NDA. As usual, those who know can't speak. But this is Mac Rumors and this community has never let a paucity of facts stop us before! And, let's be honest, there's a certain personal pride to be had for getting a prediction correct, right? So, what kinds of performance gains do you think we'll see once Metal hits its stride? By this I mean the time between now and when developers have been able to write their games to it. Aspyr has already indicated some confidence in their ability to match or exceed Windows performance of games they port to OS X. What do you think that means for individual games? 10%? 20%? More? Will we see more games that can do 60 fps in older Macs? I'll go on record and predict an average of 25% faster than OpenGL Yosemite. Some will be greater, some will be less.
