DirectX 9 was first released in 2002. That makes it over 20 years old. I'd say that it has gone well beyond any reasonable expectation for compatibility for recent processor and integrated graphics chipsets. The real issue here is that RealFlight needs to update their graphic engine. This is not going to be a trivial or simple undertaking and from what I understand it is being undertaken by realflight but there is no current timeline as to an expected release. You are fortunate to have bought a gaming computer with an actual graphics card that doesn't have to rely on the integrated graphics chipset. There are many who only have the Intel 12th gen graphics to relly on and are completely out of luck for the moment!
