Hi,

it seems that __GL_FSAA_MODE has no effect on offscreen
rendering buffers under linux. Using an on-screen buffer
works great with all the various FSAA modes. I am wondering
why that is, and if windows users have the same problem
or if it's yet another linux-disadvantage. I'm using
the latest nvidia drivers....

Regards,

	Toni

Have you tried asking for multisampling when you create the pbuffer? Maybe
the environment variable is only meant to affect on-screen buffers.

Cheers,

Hi Jon,

adding

GLX_SAMPLE_BUFFERS_ARB, 1,
GLX_SAMPLES_ARB, 4,

to the attribute list worked out fine. Thank you for the hint!

But I still dont't know which settings match the ones I
can setup throught the __GL_FSAA_MODE variable. There
doesn't seem to be any documentation on GLX_SAMPLE_BUFFERS_ARB
or GLX_SAMPLES_ARB.

Cheers and thanks again,

	Toni
