Just for a bit of fun, here's a comparison between the Just Flight Piper PA28R Arrow III (or IV or whatever) in FSW and in P3D V4, and purely for the comedy value of alluding to that 'Arrow to the Knee' meme from Skyrim, I took this particular Arrow to Kneeland Airport in California. And you thought this comedy stuff was just thrown together eh?
Some things to note: FSW is on medium settings with no AI traffic because my PC struggles a bit with it at the moment and will continue to do so until I put more RAM into it (next week), and it is apparent that FSW is not optimised properly yet since it is rubbish in full screen mode and shouldn't be if P3D V4 can run like this, because P3D V4 is on the other hand on pretty high settings and has Active Sky and Cloud Art in there and also has Terraflora in there as well and the AI traffic is up high too and all the fancy HDR lighting options are ticked.
For performance reference, the computer has a ASUS Strix RX480 GPU with 8Gb of DDR5 RAM, the processor is a Kaby Lake 7th generation i5, the motherboard is a ASUS Prime Z270P with 4Gb of Corsair Vengeance DDR4 RAM on it, both sims get about 45 FPS on the noted settings with that hardware at present, but performance is brought down somewhat by FRAPS.
Other things worth noticing: The lighting in general on the textures in FSW is better because of all that PBR malarkey, but the PA-28R does not have internal objects casting shadows in the VC (yet), which are there in P3D, although FSW does have directional lighting affecting the surfaces, so things like the ambient light falling on the panel do look better than in P3D and FSX, but those large moving shadows certainly are missed in the FSW version at the moment as they do add a lot to the feeling of being there:
