@Alien

One advantage of using OpenGL is that it's cross-platform, meaning it works on Linux/Mac OS/Windows. Another advantage is that sometimes, vendor-specific extensions are introduced which allow upcoming hardware features to be toyed with early on.

The primary advantage to Direct3D, at least for me, is the cleanliness and precision with which features are implemented. For example, the new patch types play along with the geometry shader when no tessellation stages are present, whereas the OpenGL extension doesn't allow the geometry shader to operate directly on a patch.

One interesting thing to note is that the OpenGL tessellation extension specifies a barrier function in the control point shader, due to the fact that it allows you to read back per-output-control-point data from any execution.

Hello!

I am not very good at OpenGL, and before starting to learn it I want understand some advantages and disadvantages.

P.S.
Sorry for my english=)

It's nice to see OpenGL catch up to Direct3D. Now I can play around with the tessellator in other operating systems.

Good game Khronos!

But now open-source drivers are not one but two major versions late!

Well, that's why I said "Like id Software". They only supply a binary, nothing more, nothing less.

Though obviously there's always extra work involved...

why not port it to Linux as well?

because it's more q&a and support work

Blizzard will follow? They've been on the Mac for a long, long time.

But it's definitely good to see other operating systems are getting more attention from the "big" game developers.

And I do understand why they choose Mac above Linux. Because you'd basically limit yourself to NVIDIA cards, though the open-source ATI drivers are hopefully going to change that.

On the other hand though, if they already have an OpenGL renderer, why not port it to Linux as well?

This is indeed awesome news, I really hope this push from Valve will change things for the Mac as gaming platform.
