I can't find anything on how to hint to the driver to disable any antialias. I'm using a very minimal passthrough setup yet I notice my driver is still doing what looks like MSAA. I want to disable this, or at least give a strong hint to disable it, so to save performance. As I will be doing deferred rendering with my own SSAA.

    \$\begingroup\$ OpenGL does no Anti Aliasing by itself. What you are looking at might be linear texture filtering. \$\endgroup\$

  • \$\begingroup\$ @Mr.Beast: What makes you think texture filtering is related? Question is clearly about disabling AA. \$\endgroup\$

  • \$\begingroup\$ @KromStern Linear filtering makes the textures blurry, which can be misunderstood as anti aliasing, but I agree a Screenshot is needed. \$\endgroup\$

OpenGL drivers allow user to force enable AA. I'd like to see a workaround of that too, but I'm afraid there's none.

Possible solution would be to render to a texture through FBO (which is not controlled by drivers AA setting?) and then render that texture pixely-perfect to screen.
