The following are known limitations in this release.

Viewport 2.0 ‘graphics hardware does not have sufficient memory’ error (MAYA-34609)

When using the Mac OS X platform, if you encounter a warning in Viewport 2.0 that your graphics hardware does not have sufficient memory, you can workaround this issue by setting the environment variable MAYA_OGS_GPU_MEMORY_LIMIT to the amount of graphics card memory (in MB) that you have available.
For example, if your graphics card has 6GB of memory, set this environment variable to 6144.
