they are adding more OpenGL support but through a Mac ApI called GLL . It now only works if you have a MAC. second if you run WOW with -opengl you get almost all effects turned way down and they are grayed out and can not be set back to where they were before patch 4.0 . This is because the new graphics engine that did many effects with the CPU have now been moved to the GPU and require DirectX. Old VIA graphic cards that worked on the old engine are completely shut out and cant run the game even. Hardware Mouse support was added a long time ago in the old Graphics engine but never turned on. they just pasted that code into the new engine. All the programmers are working on the GLL layer for Macs and no effort is being put into OpenGL for windows as they plan to migrate all Graphics to DX9 and up off the CPU .
