It's not that it would spoil the experiance. It's more about having learned the hardway too many times, computers and I don't get along very well. And I'm not blaming the computer.
Add to that, my spare time is very limited. So when I do have it, I just want to fly, not spend time learning new programs, tweaking things, and troubleshooting.
After countless hours the last couple years messing around with things to get FSX to run glitch free with good frames, I don't want to make any changes or add programs etc. My philosophy these days is if it ain't broke don't fix it. At least until it's time for a new computer.
