My only issue is that once again here is a new technology that requires developers to support it in the game. It isn't just an automatic thing. And we know how they like to take shortcuts and save time/money. If this is similar to how it works in the XBOX then maybe developing it with the console in mind will translate easily to the PC? That's the only way it'll probably proliferate on the PC.
So as it is now, we have to wait to see how individual games utilize it, as it is game-based, and other games just won't benefit. If only a handful of games utilize it, then what's the point. So I guess time will tell how ubiquitous this becomes.
I'm also all ears for suggestions on how to benchmark this. I'd love to show the advantages, the hardest part will be consistency. I'm also not sure if the feature can be toggled on or off, or if it's just "on" the whole time regardless. No idea how it will be implemented and enabled.
