One word, Stunning! Well worth the money, and by far the best visual enhancement available for X-Plane. Couple MAXX FX with the Hi Res scenery packs and you've got the perfect combination. Thanks for the great work once again. I was leery about adding another scenery enhancement, fearing my frame rates would take a dive. This was absolutely not the case, and I'm running XP 10 on a mid 2009 Macbook Pro. So if you're running a machine built specifically built for X-Plane don't hesitate to purchase Maxx FX, you'll be glad you did.
