CATALYST and OpenGL 1.5

you’ll have to forgive my limited knowledge, but i tried to download OpenGL 1.5 from my graphics card site (ATI) and found that they only provide catalyst drivers. If i have catalyst 4.2 do i need openGL 1.5?

OpenGL support is included in the display driver.

If your 3d card actually supports OpenGL 1.5 is a differend story though.
