View Full Version : How is ATI Catalyst implementation of Shading Language?

03-24-2005, 07:33 PM
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?

Developing GLSL on ATI Radeon 9X series is ... challenging.
You need a Radeon X800 (the 'X' series) - apparently the GLSL implementation is better.

ARB_vertex_program is working great for me (at least for 9x series) - never had (serious) problems -.
But it's low level language.
