I recently made the jump to using Prepar3d (odd name I know) after years of using FSX. My main problem was the cost. Not for Prepar3d itself which isn’t cheap but getting all the addons, I use as well. I bought PMDG’s Boeing 747, 100 bloody quid and I got a discounted upgrade for Majestic Dash 8 Q400. Then there’s the scenery, weather program active sky with the cloud art. This all smashed my account to bits.
After using it for a month or so I can now say it is well worth it. It’s taken me to the place I always wanted from FSX but could never quite get to and by that I mean when I get moments when I sit back in my chair and go “wow!” and I have to say there have been lots of those moments. The fps I’m getting is always well above 40 usually between 60-120 and that’s with all my add-ons. I never fly the default aircraft they simply don’t compare to the high-end stuff and of course that’s fine.
I would highly recommend getting Prepar3d. The user interface is modern and easy to use. There is less messing about tweaking the settings for every flight. It’s stable, I haven’t had it crash yet and above all else, it looks superb.
PS: The logbook has been updated. I can’t believe I missed a whole year of flight simming. I must have flown and stopped logging.
