OpenGL supports parallax, proofs

I was talking about tessellation, not parallax. Yes, parallax mapping is possible with OpenGL; I wouldn't say "supported by" because of the nature of how pixel shaders are written.

It can create some pretty awesome effects, I especially like the cobblestone in crysis and the staircase in Mass Effect, hard to believe its a flat plane.

As for the cobblestone, that's using parallax occlusion mapping, which is something slightly different and even more expensive.

Unfortunately i'm not very familiar with opengl and cg programming, so i can make these silly mistakes, pardon.

No need to apologize. Also, while the first two links are about tessellation as a technique to increase detail, the third is about an entirely different kind of tessellation.
