Temas has been working very hard and has got a Linux version of OGRE running on OpenGL and SDL! You can view an early screenshot here: OGRE on Linux Shot.
Cearny’s also made some changes to make the GL/SDL renderer work under Windows too so we have an alternative to DirectX on Win32, he’s also looking at a DX9 version since he’s on the beta program (good man).
Thanks also go to Tels for suggestions and telling me about a bad link on this page.
The OGRE 0.99 release was very successful, with at least 7,500 downloads in the first 3 days, congrats to all involved!
