Bug Report, OpenGL 13.25 reporting incorrect properties for G-Series SOC

Question asked by shadazar on Jan 15, 2014

I have installed the Catalyst driver v 13.25 on OpenSuse 13.1 on a AMD GX-420CA SOC with Radeon(tm) HD Graphics however after writing a few Geometry Shaders with max_vertices set to > 400,the shader does not work.

 

The OpenGL driver reports the following 2 values, showing that max_vertices should be able to be 1024, but this does not work. I think it is a bug that the driver reports 1024 but the hardware will not support that. I have the same code running on different 6xxx series Radeon hardware as with no issues using Catalyst 13.12 on OpenSuse 13.1

 

GL_MAX_GEOMETRY_SHADER_INVOCATIONS has: 127

GL_MAX_GEOMETRY_OUTPUT_VERTICES has: 1024
