So last night I spent far too many hours figuring out and configuring Prepar3D v4.3 on my newly converted Windows 10 64-bit machine. After a lot of trial and error I was able to get Tileproxy to work from my SSD. I flew around the San Francisco Bay area in a C130 and that was a treat. No more generic scenery.
I thought Google Earth looked good, but I do like Tileproxy better. Tileproxy does have outdated scenery though. I was flying in for a landing at Moffett Field and passed over the Apple spaceship campus. Good Earth had it, of course, but Tileproxy just showed a bunch of buildings. Also, for those that used Tileproxy before, the world is flat whereas Google Earth shows some buildings. There's no night lighting so daylight only flying, same as it was with FSX.
I was able to load up Google Earth too so I did a quick proof of concept video.
