For DX11 to take off, alot of things have to happen. XP desktops have to become the minority - I still think thats a while off. ATI and Nvidia both have to support it 100% - That could go either way at the moment. PC games need to become nearly as profitable as console a game - Not likely Or ATI/Nvidia need to pay the developers to add DX11 features - A possibly, and ATI have got the ball rolling with Dirt2, but will they keep doing it? If not, we will have to wait until the PS4/Xbox720 or whatever it will be called. sykozis, i'm pretty sure any port of PhysX for ATI would more than likely be slower, but if the games keep building up, and with no other GPU physics competitor, ATI will surely feel the pressure The Nvidia drivers have now been hacked, so you can now use a ATI and NV card for PhysX, but its hardly ideal for ATI that every PC could potentially have an NV card of some sorts in it.
