Since 2012 sp1 tablet support has been disabled by default, to fix the annoying lag bug. For earlier versions, you should edit setenv.bat and add this string after @echo off : "set XSI_ENABLE_WINTAB_SUPPORT=0" You should also make sure, you have pen cursor feedback disabled in win 7 (use “gpedit” in the command line window and go to User Configuration > Administrative Templates > Windows Components > Tablet PC > Cursor) and turn it off. Another way i found to fix this is using the keyboard to start and stop the simulation. This is useful in case you need pressure support in xsi. But never get the pen close to the tablet surface while you do that.
