How do you test a game like FSX flight Sim for cor

In trying to get DOF to look somewhat correct fro Microsoft FSX instead of just maybe uniform blur with values as provided by many on this forum, I wonder if there is a way to test to see if the Depth Buffer provided by the application is correct - as mentioned in this forum here and there. Also, for a flight sim, perhaps because the near and far planes are placed a long ways apart (1.0 and 50000.0 maybe), could that be why DOF is difficult to get working?

Thanks for any help!

I did the Depth Texh test with F12 - it showed only black even after turning all the Antialiasing off

No depth = No DOF. Unfortunately.

Sadly only Tilt Shift was working for fsx, at older mastereffect versions. I tried everything but couldnt get depth in game. But when choosing planes at main screen, there is depth buffer, but ingame = none. Only tilt shift worked so far.

And in fact that shader does not use the depth buffer, it only blurs the screen edges to emulate the effects of real tilt-shift (and it's still there in the Framework, in the CustomFX group).
