ok in the Fenix app itself when you open it up tick the 3 boxes under flight deck displays i think its called left hand middle off the app
3 boxes? I only have 2:
"Use Alternative display renderer"
"Use display synchronization"
I see the 2nd one gets greyed out when you select the 1st, which is said to help with systems with an iGPU.
All laptop have an iGPU, many also have an extra Discrete GPU, and sometimes, depending on the power profile used, they switch or cause issues with games not using the "good" GPU, so you might need to explicitly set it for that particular game, maybe this is related.
