Up to now, all my vertex shading is done using EXT_vertex_shader. And the more I use it, the more problems I have with the Catalyst driver.
I thought that maybe it was time to switch to OpenGL Shading Language. But since it is a relatively new implementation for ATI, I suspect that it can have a lot of problems too.
Can someone comment on how is ATI supporting (performance and stability) the OpenGL Shading Language with Catalyst?
