There's an easy way to make FSX run great at HIGH detail settings. All you have to do is purchase a powerful Intel Core i5k or i7k based PC, and you're sorted  ;)

My dad won a laptop in April from a poetry competition. He gave it to me, considering he already had a very good gaming PC himself (1GB Graphics - Nividia 8500 GTX). The laptop he gave me was a Vostro V13, that's 2.22 GHZ. It has a chipset and was very fast system-wise (Windows 7) and when I installed FSX it ran very well, but a bit laggy at times. So I used this and now it runs like a dream. I can't get a new chipset because the electrician said I'd have to buy a desktop PC.

Still, it's a good enough, thanks for replying.
