As I now neither afford to fly real GA airplanes nor does my health allow me to do it I have started to build at my office desk a kind of cockpit to use with the Microsoft Flying Simulator running on my PC. This is possible thanks to my good friend from the days we flow together with his Bonanza airplane in California, Nevada, and Arizona. So I got a powerful PC with a powerful motherboard, the ASUS ROG Maximus XIII Extreme with an Intel CPU 11700k, a graphics card from MSI with the RTX3080, a Samsung M.2 SSD HD pro 980 and the latest purchase, a 32" monitor that I use with a resolution of 3840x2160 and a frame rate of up to 240Hz. The setup at my desk that I am still working on has 5 monitors. The main screen is the 32" monitor, to the left and right of it I have my 28" monitors, all connected to the RTX3080. The 2 24" monitors are connected to the motherboard via its Thunderbolt 4 interfaces so that the graphics functionality of my CPU takes care of this 2 28" monitors.
Flight specific periferals I do use the devices from Logitech, rudder horn, pedals and 2 power quadrants that make it posible to individualy control the up to four engines. Additionally I have the instrument panels that Logitech offers.
It is not the same as flying a real plane, but it is the closest I can have it this days. Amazing is that my friend who lives in Hawaii and me that lives in Germany near Munich can fly, each on its own plane on the simulator, see each others plane in realtime and make trips together.
