Which/what "streaming assets" were downloaded and what are the expectations/benefits regarding each asset?
Source site for those downloads?
Did you install all at once? Changing more than one thing at a time makes troubleshooting difficult.
There should be some text or posting for each asset explaining its purpose, installation requirements, how to install, and related configuration settings, etc..
Go back a step or two and use the available Windows tools (Task Manager, Resource Monitor, Process Explorer) to look for what happens (or stops happening) when the stutters occur.
