Animate Pro 2 Recommended Configuration
Microsoft Windows 7 (32 and 64 bits), Vista or XP

1GB of RAM (Minimum), 2 GB (Recommended)
500 MB of available hard disk space for the software

The requirements are higher for the graphic card because in TBS you have the Bones tools with texture deformation which does not exist in Animate Pro 2.

The most accurate indicator for how the software can be expected to run on your system would be to try the evaluation/PLE version of both programs before deciding because the system requirements are only a
starting point. Many factors come into play to determine how well the software is able to run on any system (such as for example if you are using dual display or not; dual monitors cut the available resources from the graphic card - in half).
