Better is the enemy of good enough! There are all sorts of interests in flightsim. Some guys like to build new computers and spend time tweaking their hardware and software for performance. Some guys like to try new sims and spend hours, days, weeks, months building a new sim with airports, aircraft and other add ons, then spend hundreds of hours optimizing. Some guys just take the default aircraft and default scenery, and fly! I too am veteran of FS7, FS9, and FSX (I skipped FS2000). I have spent over 20 years and thousands of hours flying and tweaking. Right now I have FSX as good as it gets and I am done, done, done peaking and tweaking. No P3D and no FSNext, whatever they call it for me. I have a great FSX rig, great add ons, no crashes, no OOMs, just flying and enjoying. As I said, better is the enemy of good enough. Think about it.
