Its not that they would be useless in the real world, its that they would add nothing to the visibility we already enjoy in AHII but would add alot of graphics load.
Well if you really feel that way, you should have corrected all the people that posted that it was useless in the real world.
It would absolutely be useful to be looking forward and have a chance to see someone is on your 6 that you didnt know about. And that is its purpose as I described.
Why would it add so much to the graphics load? Where did that come from. Has a dev stated that or did you make it up? I hope with the level of graphics in the game, and the what you can buy in a graphics card for 80 dollars, that we are not too worried about optionally adding a little extra view window above the view screen.
No matter its eye candy advantage, the head on a stick view system in IL2 was always a fundamental and serious weakness vs AH in all of its versions.
