Direct link to spec with changes marked.

After a very quick look these are the main differences I see:

-Added tessellation shaders. They make it easier to support level-of-detal rendering where objects look good when they are near and they have less polygons when they are far away to save computation. See also.

-Added support for double-precision data in the shaders. This will allow for more accurate computations -- not sure how much this will be used in games.

-Per-sample shading. This will improve antialiasing - making edges look smoother.

There are quite a few changes in there. Some of them seem to be targeted to make it easier to port Direct3D games/apps onto OpenGL. A potential boon for developers.

Also, DirectX sucks

Oh hi Valve fanboy, I didn't know it was you.

This will be the downfall of Valve. They're putting all this money into porting they're games and Steam, but nobody will buy it on MAC.
