Been playing with it for a week after using the beta. Looks very good, way better than the previous (now freeware) release. Cockpits are nice and well detailed, however to me it just doesnt look quite as 'real' as the VRS F/A-18E for instance (I am being picky here!). Visually its a nice job. I have moved the viewpoints in the VC and removed several of the ton of provided views as its easier to pan than click through 5 or 6 to get the view you want.
Im using the modified ground friction lua in FSUIPC and it seems the PC-9 accelerates very quickly even on idle (this has been pointed out as normal during the beta process). Not tried it with default friction yet. Handles nicely though, very easy to hand fly in the circuit. Its a little twitchy in roll on my rig when airborne in cruise at any altitude, which seems at odds with a flight test report Ive read - this said it was very stable but with excellent response. Systems wise, well the default FSX turboprop modelling is pretty much evident, but doesnt spoil anything other than the reported hot starting. There is some lag but thats evident in the real thing (apparently). The nav systems use FSX vor as tacan/dme and there are several modes available on the EHSI. The IRIS facebook page has some videos of the systems in use if you want a look first.
My FSX is capped at 30 FPS and it runs at that or in the 20's around airports (except for Orbx YSTW - drops to high teens at points). My PC is a bit old, i5-760 @4GHz, 8Gb ram, GTX460. FSX is running autogen at normal or dense, water 2x low, everything else at max and AI at 60% airlines and 20% GA. So it works on lower specs than IRIS claim!
If I have some moans, they are minor. The pilot figures dont appear animated beyond moving visors, would be a nice touch if they were. The landing lights dont illuminate the ground at dusk - bug? Ive made the beacon effect smaller as it was lighting up the rear cockpit! And the cockpit floods are connected to the main panel lighting dimmer (there is no other switch for them, I found the effect too much so commented out the vclight lines in the aircraft.cfg, no floods now).
Ive been using RAAF Pearce from Rob Graham and the MAIW East Sale (FS9 but generally works well except for a rogue default building on the apron and the usual FS9 issues with trees and fences).
