I'm also having the same problem on MacPro 3.1 8-core, on Mountain Lion 10.8.5.
Have an AMD Radeon 5870 1Gb, which I thought might have been the issue with this, but on reading this thread, the problem seems to be with all configurations of Mac OSX.
I've a newer Nvidia GeForce GTX 680 2Gb about to replace the Radeon this month (I want to get into the Cuda Core era of cards for Premiere & After Effects CC work), so I'd bet that'll probably not solve the issue either, but I'll report back if I see any differences using the Nvidia drivers, which unlike AMD Radeon can be loaded directly from Nvidia's software on Macs.
Like the other guys, the problem with the video tearing on AeroFly RC7 v7.31 happens when you're doing fast, horizontal fly-bys with photographic backgrounds. It doesn't happen when you've the aircraft flying towards or away from the camera (in general).
