I'll be honest, I"m rather disappointed.
First thing out of the gate, it doesn't recognize my CH Pro Pedals. They're only one of the most common pieces of sim gear, but ok. Took me about 30 minutes to figure out how to configure them, it's a one time thing, I can get over this.
Load up an airplane, hey, 172S with a G1000...sweet. Selecting an airport was a little funny, the interface felt coarse and buggy. It wouldn't show anything when I searched for my home airport, it kept suggesting that I go somewhere else. I'm not sure how, but I finally got it selected. Time to fly....and...wait. And wait. And wait. Nice to see some things don't change. Mind you, I'm running on 100Mb/s network and a AMD Ryzen 5 with 64 GB of memory plus a GeForce 2080 card. I'm not exactly bottom of the barrel here. Finally it loads me on the threshold, ready to go.
For some reason, the airplane stuck in place. The brakes were released, the parking brake was off, but the plane just never moved down the runway. The speed tape started climbing, it said I was going 80 kts, but still sitting in the same position. Ok, something is broken there. Maybe a restart.
Out of caution, I restarted and chose the regular 172. All the setting are there and after I released the hand brake (on the runway?), I can see that it started to roll. Performance was choppy, nosewheel steering was extremely sensitive. I got into the air and started climbing. Woo, I'm flying, now, let's go find my house.
Now here's where the air went completely out of me. As I'm climbing out, I realize 1) the ground looks entirely flat and 2) there are no vertical landmarks. The big radio towers aren't there. The little radio towers aren't there. The tall buildings aren't tall. Even the nuclear power plant is completely missing and that's one of the THE major landmarks in the area. There are trees and buildings on the ground as promised, but there just isn't any way to navigate visually. Within 10 miles, I was lost in a city I've grown up in, other than being able to see the 430 moving map. I know what was supposed to be under me, but it was all just a flat sheet. After all the build up on how great the terrain would be, it was rather a let down.
I'm done for the night. I'll try it out again tomorrow, maybe turn the graphics down so I get better performance, try to dampen the flight control sensitivity, and see if I'm missing a setting about making the terrain run better. I still have to work on connecting some more hardware, but that will likely wait for the weekend.
Really hoping this improves.
