Wow Scoobe, that Archer really looks nice and your screenies are looking great, they should put you on payroll as it's making me want to revisit it since my poor first impressions on the demo.
I was not impressed with the demo either. I played with it for a little bit and deleted it. But I kept having this nagging feeling that there was more to it than the demo was showing, so I ended up buying the full version which I had a feeling I would regret. I didnt.
In the 2 months that Ive had it, there have been many updates to its performance and I can now run it with most settings high and still get 70 FPS! this on an overclocked 2600k @ 4.8 ghz and an Nvidia 560ti (also overclocked). Although I dont have an ATI card, I hear that XPX curreently has issues running on ATI cards, but they are working on it as well as other bug fixes and enhancements. Im not recomending anyone to go and buy it, but I do think X-plane will be a big player in the Simulation world in the next 2 years or so. Its just not fully ready for that role yet, but will be once there are more bug fixes and more 3PD's jump on board.
For now, Im enjoying it a lot and eveytime I use it, I find more things about it I like better.
