is there a way to use the NV_multisample_filter_hint extension to enable quincunx (or whatever its called) antialiasing on a NVidia card? I presume it would have to be implemented in the GLCapabilities…?
Judging from the specification it looks like you just call glHint(GL_MULTISAMPLE_FILTER_HINT_NV, GL_NICEST).
Ah, I see that now (that it isn’t determined by the pixel format) - should have read it more carefully. Thanks.
