You don't have to use it automatically
it is only used for applications that require it at the time of their use
as also said by thellier the program is not able to release the "used resource" after its use.
I hope to be proven wrong because this step would be of great interest to me.
And I would be able to configure other programs better.
If you are running voodoo3 with 4.1 Patchwarp3D would also be very handy.
