The same as for IntelliCAD8.0, NVidia Quadro video drivers have some problems with IntelliCAD8.1. It is not 100% rule, in many cases it could be ok, but a lot of Quadro users reported about problems. So, there are some notes about how to avoid issues:

1. Recommended video cards for working with IntelliCAD, with decreasing preference:
   • NVidia GeForce series
   • ATI/AMD (working on 4+ monitors is not recommended with ATI/AMD)
   • NVidia Quadro (it could be worked around)
   • integrated (Intel/ATI) - usually they have bad performance
2. For customers with NVidia Quadro, there are two major recommendation:
   1. Update video driver to latest possible: http://www.nvidia.com/Download/index.aspx
