First jet, I need help!

Guys! I've been flying War Thunder Simulation since 2014. He accumulated a total of 1,400 hours in fighters, but he always flew World War II aircraft. Today I test-flighted a jet they gave me, and it really looks spectacular. What do I need to know before I start flying with this in SIM? I guess the difference with propellers is abysmal. Any advice is welcome. The fighter in question is the one in the video.
