Just got the demo of LO-MAC...not very impressed at all, especially when taxing, it especially has that sterile railroad feel without any bumps, lumps in the tarmack and the air. I can say the same for FS2004 although it's getting there and has much improved since '98. I have the CH USB Yoke, Flightstick and pedal. I also have 2+ years of real flight experience in single engine piston aircraft. (Aerospatiale TB-9, Cessna C-172R and Piper Arrow) While I cannot say much about the fighter jet's flight performance accuracy (since I've never flown em) it doesn't have the true 'wrestle with the stick to keep the plane afloat' feel that Parsoft's A-10 sim had and that's a real shame because that sim is so old without texture mapped graphics! Even with the fly-by-wire systems used in these jets, there are still bumps to be felt and corrected in an advanced sim. I can't imagine any real pilot to be satisfied with these packages yet, although things have greatly improved since the last few years..
As far as LO-MACs avionics go, very cool. Everything still functions as you pan around in 3D. That's something I haven't seen in a PC flight sim and very impressed by it. Graphics are pretty cool too.
Man I gotta dig out A-10.... It's somewhere in the 3000+ pile of CD's I have...arrgh!
