Sorry to add to the pile of bug reports guys, but rounds fired at the ground using CCIP in TAS, RS, and TAS + RS modes are falling far short of the predicted impact point. :\
You can't aim a set distance above the target and get a hit, as the error increases with range, so it would appear that the problem is that the ballistic calculation is not correct and it is not a simple matter of the gun pipper being a few pixels high.
Best of luck guys! Thank you for all your work!
