Unigine 2.1 released- OpenGL 4.0 support with Tessellation

[Scali]

It's very much in existence for Linux. See here. (or the download page ) I think you can run either tropics or Heaven on OSX too via the Phoronix test suite.

I referred to "OS X and other similar OSes" with "those". Not linux obviously, anyone can see the linux download links right below the Windows ones. I actually said that in the previous part of the sentence: "and also platform-independent, as it can also run on linux".
