Hi all. I've noted with interest the rise in popularity of the Prepar3D sim. This might seem like an obvious question but, since Prepar3D is based on the FSX engine, why would a person chose to use it instead of FSX? Are the graphics better than FSX? Is performance better? Are the frame rates better? Just curious. 
Yes to all above you mentioned really plus its still getting worked on unlike the old engine which aces do not support anymore also it has a 700feet/meters underwater environment .
