I do not like processes I dont need running.
Ok thats my rant.
If you are seriously involved with 3D rendering etc. and were wanting to run 'clean' I'd uninstall everything on your machine except the OS and the 3D modelling program...and that includes EVERYTHING that is not the OS and graphic proggy.
If, on the other hand you wish to use both Deskscapes and Fences then the option intended for their joint use will be required....
