just to avoid some confusion, nvidia changed the environment vars between
12.51 and 15.12:
NVIDIA_GLX-1.0-1251/usr/share/doc/README:
__GL_ENABLE_FSAA
Setting this to a non-zero value will enable full scene
antialiasing.
__GL_FSAA_QUALITY:
This can be set to either 0, 1 or 2. 0 means 1.5x1.5
oversampling. 1 means 2x2 oversampling with texture LOD
bias. 2 means 2x2 oversampling with no texture LOD bias.
Note that this variable only makes sense when
__GL_ENABLE_FSAA is set.
NVIDIA_GLX-1.0-1512/usr/share/doc/README:
Several anti-aliasing methods are available and you can select between
them by setting the __GL_FSAA_MODE environment variable appropriately.
Note that increasing the number of samples taken during FSAA rendering
may decrease performance.
__GL_FSAA_MODE GeForce/GeForce2/Quadro Description GeForce3 Description
-----------------------------------------------------------------------
0 FSAA disabled FSAA disabled
1 FSAA disabled 2 x 2 oversampling with
texture LOD bias
2 FSAA disabled 2 x 2 Quiconx
3 1.5 x 1.5 oversampling FSAA disabled
4 2 x 2 oversampling with 4 x 4 Bilinear
no texture LOD bias
5 FSAA disabled 4 x 4 Guassian
regards,
j.
