Ifly 737 for prepar3d is my new favorite aircraft, just love the systems, graphics and feeling of flying it. I get 25-30fps with most settings on high/ultra with ASN,REX at 2540x1440 with a Nvidia 780ti in 2D cockpit, 5fps less with VC. Sure it is expensive, but it but peronsally I feel it is well worth the money. Just waiting on the ifly 747 p3p so I can throw my money at it. As long as it's less than 100USD, I'm happy.
