WGL_EXT_swap_control supported in 8.42.3??

[chrisr]

I thought that WGL_xxx were Windows OpenGL programs. So why does this appear in glxinfo?

Did ATI ever support GLX_SGI_swap_control?

I am trying to find a reason why World of Warcraft and Wine just give a black screen, and not finding support for GLX_SGI_swap_control is the only warning that I can see in the Wine trace log.

Nearly black screen here too with opengl and if i enter realm the world is drawn right but without any models (pc or npc).
And with cedega with -d3d everything displays right but the fps are too low....
Anyone knows how to fix that black screen/model problem ?
