Dad wants to fly - RealFlight questions

[Jerry Mattson]

My dad is pretty old, used to have a private pilot's license and has been hanging out at the local RC flight park. The guys there are recommending the RealFLight simulator.
I've looked through the FAQs.
Is it worth doing?
He has a 5 year old Windows box (7th gen i7, with no graphics card; onboard graphics only). The description on their website isn't super clear https://www.dynamrc.com/collections/rc-airplanes.
How well does it run on onboard Intel graphics?
