SUBSIM Radio Room Forums - View Single Post - Auto TDC consistently misses (torps arrive late always)

I am in my first SH4 campaign as a SHIII veteran and am getting a really confusing problem.

Essentially when I have perfect AOB and have merchants crossing my front at 500 meters to 1500 meters I cannot get a torpedo to hit a merchant. Whether I am locked on the target or manually moving the scope to get a firing solution on the forward tip of the nose of the vessel the torpedos (at slow or at fast settings) will never hit the target.

Leaving the sub I can tell by 25%-50% of the run time it will never arrive in time to hit the ship becuase the torpedo was not fired ahead of the target to meet it at it's speed and distance.

I have tried this in 2 different subs and 2 different campaigns (ver. 1.1) and the torpedo *always* arrive .5-1 ship lengths too slow. The problem is consistent and reproducible - it's like the TDC computer is 10 degrees retarded always.

I go back to SHIII and my targeting is dead on, so it is something with SH4 but darned if I can figure out what.

What I've Tried:
=============
1.) Different Sub - Problem is reproducible of the TDC regardless of sub.
2.) Locking on target vs. manually leading the target using the periscope to the nose of the vessel to attempt to lead more - No effect. Torpedo always arrive .5-1 ship lengths too late.
3.) Changing distance from target - No effect. The torpedo will always arrive .5-1 ship lengths behind at 400 meters or 1200 meters.
4.) Changing speed of torpedos - Setting to fast or slow makes no difference. The torpedos will still arrive .5-1 ship lengths behind.

What I'll Try Next:
================
1.) Try different torpedo classes - Maybe it's a bug TDC computing with the larger Mk 14 steamers?
2.) Go back and play the sub training in ver 1.1 (I qualified when SH4 was ver 1.0) and see if the problem occurs there as well..

I am really drawing a blank here. Has anyone else observed this effect? I cannot get the TDC to compute a proper firing solution.. It's almost like something is consistently being miscalculated.
