Edit: After finally stumbling onto Capn's original [REL] thread (instead of poking through the Download section), I've confirmed it's sadly an untinkerable issue. I'll keep the post for posterity's sake, and anyone else finding the same.

It's been a long time, fellow submariners! (The forum alerted me my last login was back in 2010-- whoops!) But having my interest in the endeavors of the Silent Service in the Pacific rekindled has brought me back, as it tends to do. I'm actually using the 3k Yd Bearing Plotter on top of TMO for this install, and I've noticed a rather quirky behavior. I don't think this is necessarily the fault of the Plotter, but it's rather probable the following occurs in stock 1.5 as well.

I decided to test the accuracy of the plotter since other similar projects have been known to be off by a degree or more, and I figured the easiest way to do this, of course, was by setting a nav waypoint and seeing if the zero bearing tracks correctly. Something tells me that there's been a change in DirectDraw protocols since release, or the devs took the lazy route of rotating the .dds itself. When correcting towards a course, the sub's actual heading is accurate, however the 'own ship' icon (and thus the plotter) never quite finishes turning to the correct heading, usually stopping about a half-degree short.

In practice, I know it can't be the fault of the Plotter itself, because the attack map still shows fore tubes on a perfectly straight track aligned with the Plotter's 0-bearing. Seems to occur only on the nav map, when the sub is correcting heading for a waypoint course; example, if you have to make a starboard turn, the sub/plotter will stop rotating with the 0-bearing juuust shy of the nav line (Sadly, I'm not an ace when it comes to naval terminology-- logic suggests I could say the icon's heading is 'port' to the true line of travel, but this may be a technical faux pas. Correct me at will.) Conversely, if you have to correct to port to hit the next navpoint, it will still stop short of the true course. If it was a matter of a misaligned Plotter, then it should stay on the same relative side of true course, methinks...

At any rate, since this happened to be one of the most recent posts, and the man himself has already weighed in, I figured it might be a handy place to begin my search. Sadly it seems like such a vague and difficult-to-describe issue that forum and web searches both failed to turn up anything useful in my case. Advanced apologies if it's a recognized issue that I've somehow overlooked, but fingers crossed someone has either run across it before and has a solution, or at least can confirm I'm not crazy even if there isn't a fix. You guys always come to the rescue!
