Default How can i fix this in GWX2???

Patrol 6... dead in 1942 by depth charges and extreme depth:

here is why. (sometimes this happens and sometimes it doesnt)

I dive down to 200 meters and im doing a fair job of sneaking away.

everything is going perfectly and eventually the destroyers loose intrest and start to leave the area. but then i notice that my depth is nearing 250 meters

the dilema: moving at "ahead slow" or giving the order to maintain "one knot" doesnt offer up enough speed to maintain depth... and as a result the sub creeps ever so deeper in an uncommanded descent. BUT if i order any faster than ahead slow the destroyers hear me and return to commence the attack.

this is exactly what happened to me just a few minutes ago. The sub kept creeping deeper and deeper and i was concerned about taking damage from the pressure of the depth so i blew ballast back up to about 180 meters. but once i reached 180 meters the sub began this slow plunge again. and WOULD NOT maintain depth unless ahead one third or faster was ordered... and if i ordered that speed the depth charge attacks were fast to follow.

now the questions:

1. Why does this happen some days and not others? there is no consistency in this event (no save game was involved in any way) one day i can hold depth at 1 knot and the next day im like a stone and i will sink from 200 to 250 within 5 minutes in the game.

2. How do i fix this? i have looked for the removal of the positive bouyancy aspect of GWX2 but have not been able to locate this.

3. Has anyone else experienced this problem?

4. If there is no way to correct this issue with GWX 2... how should i change my tactics so that i can prevent it from happening again?

the traditional "go deep and go slow" strategy doesnt seem to work in GWX2 because going slow results in the inability to maintain depth.

thanks

As long as you keep the rpm at a maximum of 150rpm you can go a little faster than 1 knot. In the VIIB 3 knots will still stay silent. I think it's only when the rpm goes above 150 that you are no longer silent.

interesting, i was not fully aware that this had changed... i will give it a try, but i would think that ahead 1/3 would put me in a position to hold depth... but the DDs would U-turn and make a b-line right for my position when i did this.

back to the drawing board.

Set the speed by knots and keep checking the rpm on the gauges.

on a side note i dont want anyone to think im complaining about GWX2... i like the neutral bouyancy effect... but this seems to be a problem only sometimes, which doesnt make sense due to the inconsistency.

When a man has a problem he doesnt go to Dr. Phil and talk about it all day long.... he does one of two things...

either

A: he changes to suit his environment

or

B: He changes the environment so that it suits him

Im just trying to figure out whether to go with A or B on this one...

For now im going with A

Dive to 150 meters, if you're still sinking and the buggers are dropping depth charges, rise a little while the charges are exploding and you're at flank.

good plan, and i usually try that when i encounter this problem. but i thought that i heard somewhere that exploding depth charges do not inhibit the ability of enemy AI to detect you on their hydrophones.

is this correct?

also are there any better depth charge sound effects out there?

Yes I have made the experience too that the DD can still hear you even when the DC are going off... back when I was still using the stealth o meter it always turned red when I went to flank speed whilst the DC exploded.

And I also have the same problem in my VIIC... I manually adjust the speed to around 2 - 3 knots, this usually allows me to maintain a steady depth. Howver this is not silent running anymore.


Did this problem really occur in real life? Because if it didn't I would like to kindly ask the GWX team to fix this "bug"

The DCs exploding are noisier than you are.

well the stealth-o-meter doesnt indicate that you have been detected... it only indicates the likleyhood that you might be detected if you contibnue to do what you are doing.

I will have to test out this 150RPM strategy. the way i understand it is regardless of speed you are in silent running as long as you are at or below 150 RPM

The stealth meter should be considered a training device that informs you when you're screwing up. Other than that, it is useless.

I haven't a definitive solution for this...the go silent go deep tactic usually works, however, it pays to know that a slight increase in speed, say a short burst of ahead standard may get your boat rising again especially if the DDs are leaving already, just don't do this when they're very near or you're sure your not in their baffles...

also, I don't usually go that deep...I find that 150 to 170 meters in generally deep enough to sucessfully evade, as long as the escort haven't been able to accurately pinpoint my location....

as to the inconsistency, I've never had this problem in GWX 1.3 or 2.0 with any boat, and I've used them all except maybe the IXc/40....what I'd like to know is which boat you're using, doesn't seem to be mentioned, see if we can reproduce this problem..

type IIa problem I have noticed and mentioned, suffice to say it's a seriously clunky boat, not very useful to begin with, that's why they were all used for training post 1940... the IID is much better suggest you upgrade asap

Could this be the "Crash Dive Blues," i.e. did you crash dive in order to escape the destroyers? If you did, and you issue a new depth order before reaching the actual crash dive depth, you will not be able to maintain depth at ahead slow. I don't think that this should be ruled out until the possibility is eliminated.

So in your example, you could hit the C key and then order 200 meters before reaching the crash dive depth. If you have done this, then you are experiencing the "Crash Dive Blues."

Here is a full report of the incident:

Type VIIC...

Located at Periscope depth, about to attack a convoy. Suddenly i get the message that the enemy is pinging us. I hit the "D" key to order a dive and set ahead flank.

The destroyer passed overhead and executed a depth charge attack against me but his charges were set too shallow.

Upon his passing overhead i executed a hard to starboard turn to reverse course, ordered a depth of 200 meters.

During the course reversal the depth stabilized at 200 meters. I ordered ahead slow.

the speed reduced to about 1 or 2 knots as the turn was being completed.

I then proceeded to rig for silent running.

The DDs continued their assault, however they were attacking the wrong part of the ocean. time compression was limited to 8X due to the enemy activity overhead.

Over time i slipped away to about 2KM away from the area they were attacking. monitoring the attack via hydrophones myself and through the sound officer i was able to determine that the warships were headed back to the convoy at full speed.

At this time i looked at the depth gauge so i could order a much shallower depth. The depth gauge indicated about 240 - 250 meters (near pegged!). I ordered an immediate ballast blow which reversed the sinking trend. upon reaching 150ish meters i ordered a new depth of about 140- 150 or so. the depth held for approximately 10 - 12 seconds and began a gradual sink rate of perhaps 0.5 meter per second. The boat had taken no damage, there was no flooding... and none of the previous depth charge attacks came close enough to so much as rock the boat.

as i scratched my head i ordered ahead one third... almost right away the depth stablized and returned to the assigned depth setting.

HOWEVER... upon ordering the new speed setting one of the DDs which i will only assume was still in the area about 2 - 3 KM aft of my position made an almost immediate turn to my direction at high speed. I was depth charged and again undamaged.

my dilemna now was that if i was at a telegraph setting of "1" or slower the sink rate could not be controlled BUT the enemy could not hear me. On the other hand if i was at a telegraph setting of "2" or more i could control depth but was no longer silent.

I elected to change strategies.

I would allow my boat to sink to or near 240 meters depth and use short bursts of speed to correct the sink rate back up to 180ish.

initially this strategy worked... there were at least two more innacurate depth charge attacks, and other DDs were closing in as they had apparently renewed their search efforts!

As i once again closed on about 230 meters depth (keep in mind the assigned depth was still about 180) the latest depch charge attack was lethally accurate.

The conning tower took heavy damage... observation and attack scopes were destroyed, AA guns destroyed. light damage to all compartments, light flooding in bow quarters, bow torpedo room, and stern quarters.

The new level of damage to the submarine combined with the pressure of the increasing depth caused the bow quarters to go red.... along with that condition, the forward batteries were destroyed. I ordered ahead flank and the Electric motors cranked out their best power on one remaining set of batteries which was providing only about one or two knots. (not even enough to control sink rate or hold depth) at this point i decided to Blow ballast and scuttle the boat once on the surface.

Only about 50% of the compressed air remained, upon blowing all of the compressed air... there was no notable change to the depth, and flooding in the forward quarters had increased to a critical point.
