Hi @gordyg and welcome to the community 
My first advice would be: Optimize Windows → FREE e-book by Deskew - Optimize your Windows PC for the stage!
My second thought: when you change your audio settings, do they get saved?
We had a user where a Windows update messed with his permissions, so he needed to change audio settings every time.
My third thought: make sure that audio buffer sizes and sample rates match between:
- your audio interface (audio interface’s control app)
- Windows integrated audio chip
- Gig Performer Options
