This? But I think it was fixed in later versions of softimage. Not sure though:
Work-Around to Problems with Tablets and Softimage March 11th, 2011 by Luc-Eric: There is a strange user interface lag that affects Softimage XSI when you use a Wacom tablet. With heavy scenes or simulation, you may never be able to stop playback. Other users have reported problems with the render region.The best work-around is to disable tablet support in Softimage (any version). This will not affect any other program.To do this, start a Command Prompt using the link in the Autodesk Softimage Start menu group. If you are running under Vista or Windows 7, its best to run it as an administrator. A command prompt will will start in the bin directory of the application. Type this command: C:\Program Files\Autodesk\Softimage 2011\Application\bin> copy xsi.bat wintab32.dll And re-launch the Softimage. You should now be fine. The only place Softimage uses the tablet is for pen pressure in Weight Painting and in the compositor, and it doesnt work very well anyway. To restore tablet support, simply delete wintab32.dll from the bin directory from that command prompt.

See <http://www.softimageblog.com/archives/546> Workaround for Problem with Wacom Tablets and Softimage. This link is dead unfortunately, and we have some issues at the moment with Wacom on Linux with heavy scenes. Any info of how to resolve freezes or lags would be really appreciated.
