Interesting, as much smaller black halos where exactly what the multisampling removed on my system, particularly when running the atmospheric shader! Your graphics card is listed as supporting multisampling, and the effect should fall back to the previous rendering method if it doesn't. Nevertheless, can you check that you have GL_ARB_multisample listed as a supported extension in your graphics driver? A quick google found this reference to a possible Mac bug: http://lists.apple.com/archives/mac-opengl/2010/Mar/msg00009.html It refers to a bug report "(radar: 4917355)", if that means anything to you. If it is a long-standing Mac bug, then we have a couple of options for working around it: 1) Add another rendering control to enable multi-sampled trees. I'd prefer not to do this unless there is a perf degradation with this change, which I'm not seeing. 2) Add some platform properties and enable the effect based on those. Hooray on the forums has suggested that we expose more static platform information through the properties tree so we can extend the current About dialog to include more diagnostics information that can be submitted in support requests to the forums or bug reports. -Stuart ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
