Now there's something that oughta make you wonder just WTF is microsoft doing that this lag should exist in the first place, i have just got win8 forced down my throat by my laptop manufacturer and this... directx games remais the only reason i cant jump ship
but it is there fault that they are pushing devs adjust to there new ways of things. trying to push away legacy apps and trying to convert to people to new things. in a way I can understand Gabe from valve.
pushing devs toward new things is good. You can always run things in some sort of emulated or compatibility mode later when systems are more powerful. If you don't do that, you end up with a huge bloated mess of an OS. We already have enough bloat in win8.
