Can't believe I'm going to ask this but...

Carenado does a poor job with complex FMS-equipped aircraft - their Hawker 800 had numerous problems with the so-called Proline 21 emulation - FMS problems, autopilot inaccuracies etc.

 

Bert did some excellent "clean up" mods on the Hawker that fixed some of the issues, but it still is a frustrating aircraft to fly.

 

However, I have found Carenado emulations of piston-powered GA aircraft to be quite good. I own the PA23 Aztec, and I find it to be an excellent performer in P3D, with good frame rates, and quite accurate performance. It has GTN750 support in the VC. My only complaint is that they modeled the aircraft with turbocharged engines, and though there are some turbocharged Aztecs, the great majority of PA23s produced were normally aspirated.

 

The Aztec, like most simulated (and real) piston twins does have limited visibility due to the engine nacelles.

 

I can heartily recommend the Milviz Baron and Cessna 310 also. Both aircraft are excellent performers, and both have native GTN750 and WX Advantage radar support in the VC - but again, like most low-wing piston twins, out-the-window visibility is somewhat limited.
