Time Compression Issues
 

Does anyone know if there if there is any real fix for this? I was looking at some of the coding, but I dont really see anything that handles time compression other than main config.

welcome aboard!
 

You know, I was getting seemingly random crashes, and then I figured out the cause. I'm not 100% sure what setting it was anymore though. Basically, the crash was caused by the game running out of memory. 2 Things:

1: Grab the 4GB of Memory patch if you don't have it already.

2: Next time you experience it, try to save in a new save slot, don't risk your last good one. Drop all the graphics settings and see if that fixes it. It may require closing the game and restarting it. If that fixes it, try bumping the settings back up one by one until you find out which setting it is exactly. If I recall, it was one or both of the terrain object settings doing this and dropping it to the half way mark or so fixed it. I know that some of you are saying it wasn't near shore, but that doesn't mean that the game isn't buffering terrain models anyways. I suspect that what happens is that the game keeps textures and models for all objects you have seen on the patrol loaded into memory.

Edit: Oh, sorry for the slight necro, but the post was still on the first page so it's not really that bad I guess.

Very good advice. A little curiosity often leads to better gameplay and you gave great advice there.

It brings me great pleasure to award you Necro of the Week though. Congratulations....I think:D

having this same issue. having a blast these past couple of days. second patrol i found a large convoy on the way home. taken damage and was low on fuel/torpedoes. tried to TC past them. no matter where i was in the game, anything above 128x greatly reduced performance. i tried to make it back to pearl with the low TC only to have my game CTD half way there.

I remember running into this problem before and it being the primary reason i stopped playing. i found the memory fix was already enabled. i heard this could be a problem with 1.5 and uboat DLC. tried to uninstall, but it seems linked to one another through steam. i cant run one without the other.

i know its been almost half a decade, but any help would be appreciated.

It's usually better to start your own thread freqimann, otherwise you end up at the bottom of page 2 of a thread, and might get buried when someone sees how old the thread is... but that's neither here nor now. Some are going to wonder if you've been in a time warp

Sorry, distraction... If your crew has been injured in any of the damage you speak of, or if maybe you accidentally left them at battlestations for a few days, their "efficiency" deteriorates, and the game limits you to 128x TC in those cases. If you have a lot of traffic around you, especially airplanes, the game has limited "throughput", and will stutter trying to display it all. The 4 gig patch helps, but you're still limited by your computer and its "background" apps running, the amount of RAM you have, the free-space on your hard drive, and the vid card you're using. Do you have any of your system specs, or if you have any mods on your game. Also, what folder do you have the game installed in?

And we really should welcome you to SubSim :subsim: since this is your first post, though almost 9 years later... :salute:

i figured that would be messy. if someone already had this problem, why make a new thread? when i post, this thread gets bumped to the top of the list. correct?

is the 128 limit you speak of a soft limit? i'm able to exceed this, it just bogs down the sim and starts getting SLOWER the more i increase. that defeats the purpose of TC. any tips for dealing with this, if that is the case?

-i'm using a mod that decreases the amount of enemy air traffic. that's it.

-Path: D:\Steam\steamapps\common\Silent Hunters Wolves of the Pacific

-Intel i5-4690 @ 3.5GHz
8 GB RAM
Radeon RX 570 4GB?

update: successfully removed UBM DLC. it involved a complete reinstall. after going through and setting up things the way i like i found that all map measurements are in nautical miles rather than yards. i'm willing to put up with a lot from the downgrade, but this is harsh. calculating speed using tenths of a nautical mile? what a nightmare. i havent really bothered to test if this works. the absence of yard measurements is just to distracting to get deep into a patrol.

another thing: is the steam version really locked at 1.3? i read a thread saying that yard measurements could be taken in 1.4, but i don't see that in the version i'm using.

welcome aboard!
 

True, the cream rises to the top. I always forget whose thread I posted in though... :oops:

That is a cfg file that limits the TC when you have damage. That's not what you are encountering, from your description. 128x is often the maximum that the game will "play" smoothly when near a lot of traffic, such as when near a harbor or bay with a lot of traffic in it, or when near a battle scene. There's usually not too much to be done for it, other than try to makes things more efficient for the game.

If that's the Webster version, that works good. However, it is NOT for ver 1.3 of the game...

good path to the game, excellent computer specs, even if a 1st gen i5 (which it's not, since it's 3.5GHz). Plenty of RAM, good vid card...

That is v1.3 - it did not do "measurements" correctly. Most of the mods you will find will be for v1.5 (Uboat Missions) of the game. A very distant second would be v1.4, and very few, if any, for v1.3

You cannot use the Ubisoft v1.4 update on the Steam version of v1.3 - it just will not do it. You have to "update" to the Steam version 1.5 Uboat Missions add-on when doing Steam v1.3. Steam with Steam.

Make certain with the game that you have the correct executable file with the Large Address Aware set on it. When doing that, make certain that the executable is not write-protected, else the LAA will fail, without message. With your computer, you should not be experiencing bad lags, unless you run into a lot of traffic in the game. Make certain that the video display driver matches the "Native" ("Recommended" in Windows) resolution of the display monitor (unless you have a CRT), and that you have the game set to the same resolution. Do not do any "over-sampling" or anything like that, because that will add overhead.

Possible fix
 

Hi,

Just a few days ago I have experience this TC issue where going pass 1000x would dramatically slow the game.

I discover that the sound was the problem and as I switch to a different sound device (driver) it work flawestly again and I can go to 7200x no problem.

Hope this help.

And, here we are all the way out in 2021 and the problem is still there. It is so random, I can't identify any suspects. Whatever the problem is, it gets saved as code in a Save Game so saving, quitting, and restarting doesn't help. It is a lot more than just a "stutter". The system is unable to monitor the keyboard or mouse, so if you want to do something via the keyboard, such as surface, you must hold the key down for as much as a second.

There are all sorts of reasons for that to happen. Number one used to be computer resources, but most modern computers can handle SH4 with two hands tied behind their backs. The use of Time Compression can also cause issues, and if you are shelling out to the Windows desktop to do email or other chores while playing, that can introduce troubles. Also, doing your "Saves" on top of each other, that can also contribute to the issue. Make each Save unique with a new name, and delete old, unneeded Saves - using the game interface...

The Stock game doesn't gain too much advantage by their use, but any modded game will generally benefit from applying either LAA or the 4Gig Patch - LAA is pointing at a CapnScurvy write-up on its use on his new install of Windows 10, and the links for the download are in his thread. The 4Gig Patch is from NTCore, and has a bit of a write-up also. You do need to have a 64-bit Windows to use those little applets. Another way the issue you describe can happen is by a bunch of traffic in your vicinity, which might be an area of roughly 30-100 square kilometers, or 20-60 square miles. The traffic doesn't have to be seen yet, for it to slow you down. But if you have a minimal computer system, no LAA, and encounter a 24 or more ship convoy or Task Force, that can really impact your computer - especially if there are errors involved.

I mention this, because some older mods have improperly terminated ships, that just keep circling the globe, while others keep spawning, and the "group" of ships near you might be 100 or more DD. This was bad in some older FOTRS versions, but it was not alone in this. If that's what you have (FOTRS - not FotRSU), let us know, and we have a small "patch" somewhere on one of my hard drives in the basement we can post somewhere for you...

There have not been any updates to the game or many of the mods in more than 10 years .. any issues around back then are still in the code.

One of the biggest problems is the 2GB memory limit. You need version 1.5.0.0 of the game to be able to apply the 4GB memory patch. Have you applied that?
