@mqualls2Found a light program 'Prio' that is able to save the priority setting if that helps
@mqualls2No, no, no! You don't want to run all of your games in realtime. You're going to kill your GPU doing that.
I have a GeForce card, and was able to fix all my stuttering and audio issues without touching Task Manager, or any in-game settings. In GeForce Experience, I needed to "optimize" the game.
Did you set the priority of the game to real-time?
