At least I've had the problem from the beginning, it's not a result of any of the patches for me. I also think that the delay might have something to do with the framerates, but if that's the case, pretty much everyone is guaranteed to be suffering from it; my framerates aren't stellar, but they are quite acceptable. Also, if rendering slows down control input (and physics etc.?) it sounds like an issue with prioritization in the code and shouldn't happen. At least for me, iCoD is the only sim that suffers from this issue so badly.
Well my situation is exatly the same. I have this problem since the first time. I put the game on the shelf, becouse I thought this issue will be fixed soon. Well it hasn`t been fixed.
Maybe more people have it than we know. Only they haven`t noticed yet, or their delay is very short. Maybe it is only a minor problem and effects only a few users with a certain hw combo.
Anyway, It would be interesting if some people could test the followings:
-Press the mg trigger and check when the gun starts to fire
-Look at the virtual control stick. Make a sudden move with your joystick and check that the virtual is in perfect sincron.
-Click onto an instrument in the cockpit by mouse and check if the clicking sound has a delay or not.
