I'm at work but I will post when I get home in 2 hrs unless someone beats me to it...
FPS... not quite as good as Carenado's latest, but not as bad as Mustang/PMDG etc
Here's a quick breakdown of my payware against default C172 VC. I always conduct tests without vsync and all traffic, weather, and autogen is off. Test mid day at a 60% vc zoom at Edwards, avionics powered up.
Carenado 1st gen stuff (Arrow/Seneca/Cherokee/Mooney) = equal with stock plane
Carenado Bonaza F33 = 80% of C172 (ie I lose about 20% fps compared to default c172)
Lotus L39 = 75%
Orbx Lancair = 70%
RA 1st gen stuff (Scout pack, SF260 etc) = nearly equal or 90%
RA piston Duke = 70%
RA Turbine Duke = 65% (with new VC options enabled, otherwise same as piston)
LevelD 767 = 60%
ES Citation X = 55%
F1 Mustang = 50%
Obviously, others will get different results but I notice this stuff because I'm not running the latest n greatest Sandy Bridge CPU

If you have a somewhat modern PC you'll be just fine with the Turbine Duke. My system is circa late 07 early 08 so I'm starting to notice the increase in FSX modeling and decrease in my fps LOL
