How can I force the game to use a preferred GPU?

Hey @Mootill2 

Apologies, what type device (make/model) are you playing on? I was curious because in some cases, for ex. If you have a laptop without specified hardware will still run your integrated graphics on some level and some often try switching to save power which may be causing hiccups in performance. 

Also to confirm, do you notice it flip flopping because your system resources change in Task Manager or due to performance changes? Within PGA Tour settings you can't set a specific GPU and I wanted to check how you saw the change.
