Hi Zhuwan, I am not aware of any changes that would introduce a regression in anti-aliasing, perhaps rather than a bug you have confused the set up of aliasing.
The OSG by default does not enable anti-aliasing, this applies to 3.2 the same with all previous OSG releases. So running the osgviewer with cow.osg and without the OpenGL driver overrding to switch on anti-aliasing you should see no anti-aliasing in any OSG version. To enable antialising you have to set the Traits::samples and sampleBuffers values when setting up the GraphicsContext. You can set the default via the OSG_MULTI_SAMPLES env var, or via the command line i.e. osgviewer cow.osg --samples 4 I have just tried this on my OSG svn/trunk + Linux/NVidia system and it works just fine. If there has been a difference in behaviour then it'll likely be down to the OpenGL driver playing games with auto-detecting the software that is running and choosing defaults. This does happen, but I haven't heard this happening to osgviewer yet. Robert.
