Problems with Jets

I have gotten close to airport and Jet freezes and then program exits. I have 4 gigs on card, Rysden and one Tb at 3.4 mgz. The taskmaster performance chart in Microsoft show 32 percent memory use and high power usage. Simming for many years, and this is improvement over FSX but stability is questionable. Please help.

4GB of RAM?! That aint going to cut it lol. I have 64 just upgraded from 32gb and it uses around 12-20gb of ram for me. I do play on Ultra settings though

I have 16 gigs of ram. The 4gb is for video card. See below for system:

and thanks for responding>
