il try reinstaling everything...maybe try NYGM...alternatively im gonna wait for living sh5...tnx for help but i think this kind of **** doesent happen to you and i hope it doesent...

Since GWX is the only mod you are using, a complete uninstall, registry cleanup, and reinstall should take maybe 20 minutes. I'd encourage you to also re-download GWX3 before you do the reinstall. All told, you will invest less time than continuing to try and pin down the problem. Why fight it?

Here is some technical information about the type VIIC (sound profiles) from U-boat archive.net, enjoy!

U-boat Information

h) Sound levels (from testing with "U-45 and "U-51")
(updated for VII C boats after testing)

Boat lying on the bottom
Sound from auxiliary machinery at 250 meters distance
Operating: Underwater telegraphy converter and gyro compass

Not heard
Gyro compass-circulation pump
Gyro compass- converter
Extending attack periscope
Extending air search periscope
Tracking motor in torpedo data computer
Dive planes electric drive
Dive planes (hand drive)
Main rudder electric drive
Quiet
Radio converter
Hydraulic oil pump
W.C. pump
Echolot (shallow depth device)
Control valves for the periscope drive
Engine order telegraph without buzzer
Main rudder (hand drive)
Moderately loud
UT converter
Auxiliary LO pump
Retracting attack periscope
Retracting air search periscope
Compartment ventilation fan
Engine order telegraph with buzzer
Loud
Main drain pump
Walking in the boat
Very loud
Auxiliary drain and trim pump
Air compressor
Drive motor for turning attack periscope
Speaking in the boat
Working in the boat
Echolot (deep depth device)

Boat hanging on the periscope

Sound from auxiliary machinery at 250 meters distance. Motors stopped. No auxiliary machinery except for UT converter and gyro compass.

Not heard
Extending air search periscope
Extending attack periscope
Moderately loud
Retracting air search periscope
Retracting attack periscope

Boat at attack depth
Boat driven at attack depth in a circle of 500 meters radius
Not heard
One motor KF = 50 RPM
Attack periscope
Dive plane driving motor
Both motors KF = 50 RPM
Compartment ventilating fan
Both dive plane driving motors
Quiet
Draining and trimming with air
Operating both dive planes by hand
Both motors 80 RPM
Loud
Draining and trimming with auxiliary drain and trim pump
Both motors 140 RPM
Both motors 120 RPM
Both motors LF 100 RPM
Very loud
Both motors 250 RPM
Both motors 200 RPM
Both motors 180 RPM
Both motors 160 RPM
At starboard 110 and port 90 RPM the noise is weaker than with both motors at 100 RPM
Draining and trimming by means of air at 80 RPM or less: slight noise is audible.
Detection range with different RPM rates (submerged)
At 80 RPM: 4500 meters (Detection range particularly large because of howling sound)
At 160 RPM: 5000 meters (Detection range lowered.)

From the U-boat owner's manual, about as official as it gets...

Kudos to you UKönig!
Thanks for the awsome info!

So it looks like GWX is not hitting us with random stuff... very intresting

This means the game probably requires a high degree of attention, care and situational awarness (and a bit of experience) from each wannabe kaleun who would try to put his feet in this kind of simulated shoes...

That is always presuming that GWX accurately models these sound profiles. And that the SH3 game engine actually is flexible enough and precise enough to permit such modeling. I don't know if either of these is true, but I'll bet there are people around this forum who do.

Otherwise, it comes down to individual experience to ascertain what is really going on in the game (as opposed to what was true R/L).

For example, UKönig's post basically says that running slow (80 rpm) doesn't significantly lower detection range compared to running about Ahead One-Third (160 rpm). Is this borne out by experience?

Detection range with different RPM rates (submerged)
At 80 RPM: 4500 meters (Detection range particularly large because of howling sound)
At 160 RPM: 5000 meters (Detection range lowered.)

Other examples: I have seen posts indicating that, in the game, the Echolot is never heard by the enemy, and this is borne out by my own experience. In R/L, raising a scope does not produce any noise, but lowering one does. I haven't noticed such behavior, but it might be present in-game.

Most of the activites classed as "Loud" or "Very Loud" are prevented when in Silent Running. But turning the attack periscope is allowed, and, AFAIK, does not increase detection probability.

We are more fortunate than our R/L prototypes, because we can learn from all of our experiences, successful or not. They only learned from the ones that didn't get them killed.

In the end, the model is what the model is, and it is not a U-boat.

Some suggestions:

re-install just in case you have detection range settings corrupted

after that:

try

1. waiting for bad weather
2. keeping a distance of 2000 meters to the escorts
3. minimizing up periscope time
4. running at 50 RPM
5. occasionally switching off engines altogether
6. keeping your bow turned towards the closest escort

Don't get frustrated by a failed approach, take notes about the situation instead and try something new on the next attempt

The approach will get more and more difficult by the years, so:

7. Start learning how to shoot from a minimum distance of 4500 - 5000 meters

To be fair, I am trying to recreate the page the info was found on, and it was from the original german type viic technical manual. I don't know how to read some of the charts or mathematical formulas involved. And some of the equipment that makes noise in one state seems to make more or less noise in another state. I presented it here for the reader to try to interpret his own understanding on the document.
I am learning everything that I can about the subject, and I will play the game based on those rules. If the game falls short, I will realize it (and start 'gaming the game'), and carry on as I know something that it doesn't.
Besides, I've said here and elsewhere, I have an unhealthy devotion to the subject matter, and I'm sure that a lot of other readers/players here do as well.
I know where I can get more of this "submarine-porn"
