Time compression at TC > 256
Hey all,
I'm noticing something odd in my campaign patrol. When I left base (Pearl) I could ramp up TC to 2048 or higher and the game would still run smooth as glass. The keyboard was responsive, the mouse was not jerky, etc. The only way to know that time compression was set to something other than "1" was by the speed of my sub on the tactical map or by looking at the TC setting in the lower right corner of the screen. Somewhere during my patrol something changed. Now, time compression is only really usable up until TC = 256. Anything higher than that and the following things happen:
Because of this it's taking much longer to return from patrol than it did to get to my patrol area. As you might imagine, this is somewhat frustrating. Has anyone else ever experienced this change in TC behavior during a patrol? Is there anything I can do to fix what's happening? |

Happens in stock game usually when there are a lot of things for the game to keep track of. I get it most often after sinking an entire convoy, the game continues to process all the life boats, rafts, floating boxes and barrels until I'm 20 or so miles away. Some mods aggravate the effect, thinking there wasn't enough debris after a ship went down they edit \Data|Library files debris.dat and LifeBoat&Debris.dat to double or triple the amount of floating junk after a ship goes down. Looks great for 1 or 2 sunken ships, sink half a dozen and the game slows down because it's tracking all that movement.
If it's not related to a recent sinking (if the game doesn't smooth out when you're 20+ miles away) or near something that appears as a contact 5-10 minutes after the stuttering starts, check your video and sound drivers. Never figured out why, but unless the sound card can process audio correctly it somehow makes the video stutter even if the video card and drivers are perfect. |

CTD - it's not just a job

If you have a 64-bit OS, you could try this: Windows10; Large Address Aware; SH4 Install - CapnScurvy speaks specifically about a Windows 10 install, but any of the other 64-bit Windows is very similar. He installs Silent Hunter 4 and LAA (Large Address Aware), to set the SH4.exe file. It allows the game access to more than 2 gig of RAM (or rather tells the OS it can address more properly), and that will sometimes - sometimes, not always - let the game run smoother. If you have a 32-bit OS and more than 3 gig of RAM, let me know, and I'll accelerate my tutorial for that. I have had success with Windows XP 32-bit, but I still have to try things out on Vista and Win7 32-bit, to see if similar is available, but I'm lazy right now, and the Vista machine is sitting in the corner unplugged, missing a hard drive... does not look good...

I'm still chugging along with an ancient Dell XPS 400, Win XP media center (kind of half assed XP pro with a movie maker app) upgraded a few times with a Pentium D 3.4, 2 gigs RAM, Nvidia GTX 650 2 gig, and a SSD. Running SH4 off the F drive (the SSD) I get better performance than 12 years ago, but if the patrol runs on long enough and I get 300,000+ tons (happens a lot since I have all these resupply bases) it will sTTTTTTart sTsTsTuTTTTTering in TTTTTTTime compression. Only cure I've found is quit before it gets up to 400 thousand, return to base, end patrol, start a new patrol and the stuttering is gone. Until I go crazy again, of course. Not really an issue if I don't get carried away, medals max out before 200 thousand tons anyway, and by the second patrol I have more renown than I can possibly spend.
Get back to base, end patrol, see if it does it after starting the next patrol - save files getting fat is my main theory, although I haven't proved it yet. |

It's kind of normal.
256 compression in extremely crowded areas and even close to land cause a lot of stutter due to the amount of elements the game has to process. I have noticed this happening both in SH3 and SH4, keeping around x64 compression seems to prevent this issue though.

Didn't read this, sorry.
It might be a memory leak in this case, did you set up Large Address Aware before playing?

I decided to throw that install way and re-install the game from scratch and try again. Quote:
