The idea is since there are known issues such as legacy adapters that a known to cause performance problems when connecting that is fixed by disabling hardware acceleration in msp connect.
why not set the setting in a rule to disable hardware accelleration for msp connect or enable peer to peer or limit image capture.
then with a filter like
Hardware > Video Adapter Name > Contains > matrox
you can easily make to correct settings - a one and done versus - one person is fixing adhoc and they leave so next person experiences the same issue.
it's actually to better fine tune the settings for MSP connect - if all the MSP Connect settings could be available in the rule, that would be fantastic.
