12th gen and windows 11 Hardware question

Still deciding after reading numerous posts about fps near large airports etc dropping to unplayable whether I should not up grade or should just try XPlane 12. I would have thought that with the 12 gen laptop c/w 3050 I could cruise at 30 fps and not degrade. I’ve turned everything off for traffic. I’ll be flying at 70fps and then start to come to any airport and it drops to 30 and then it just stops completely.

Any comments welcomed.
