Hi all, I was wondering if anyone is using PREPAR3D instead of FSX? It looks very good(yes I know that it is based on Micro$oft's ESP which was sold to Lockheed last year). It is a bit pricey but it does look smoother than FSX. I may just bite the bullet and purchase the software. FSX and it's fault are starting to get old. I have viewed You Tube videos on a comparison between FSX and PREPAR3D but any comments would be appreciated.
