I have heard reports that antialiasing is a bit of a problem with OpenGL because application settings can be overridden by the graphics card configuration. Is this correct? Is there a way to force antialiasing to be always on? And, are current OpenGL antialiasing techniques as good as traditional CPU-based techniques?
As far as I know there is no cross-platform way to enable on the driver side antialiasing through opengl extensions.
The ARB_multisample extension may interest you to perform antialiasing with multisampling.
Thanks for the reply. When you say there is no cross-platform way, are you saying that there is a way but it requires platform-specific code? I don’t see that as a major problem.
