Hello dear people,
did you try with Valve Hammer Editor with ATI/AMD Readon HD Drivers
I have been tested with AMD/ATI CCC 10.x 11.x and 12.x works with VHE now.
CCC 9.x doesn't work

- I have been found opengl() function from library by ATI-Library was not included. It has been got error of gl_opengl and gl_draw_opengl.
I hope you because you work with VAlve Hammer Editor with ATI/AMD Drivers now. I would wish you happy mapping now! Don't be sad! Please keep happy and make your dream of level design
Thanks for support & suggestion
