I have dual core and as far as i understand sh3 doesnt use the second(sort of) so it is actually pretty anoying runing at 1024 and sometimes fps drops dramaticly.IN any case indeed low tc is best solutions,it can make IX patrols really long but it wont let you out of high tc when have a contact in a fog 3 seconds before collision.

I play with 256 and yes it takes 4times the usual to go anywhere but hey, you can do other things than watch the monitor,what are the watch crew for ? :up:

There is one problem however, when the radio operator recieves a radar warning from the Metox or Naxos there is no audible warning, there is only message displayed in the dialog box.
Otherwise I would just set TC to 64 and chill out infront of the television... but because of this limitation I don't risk the lives of my crew.

I would like to have a mod that makes someone of my crew shout out when the FumB recieves enemy radar waves. Ala "Schiff gesichtet" style.

That is often true regarding dual core processors default operation.

I use an optimizer program that shares out the load on my dual core processor evenly.

IE: If my processor is working at 30% capacity... each of the two processors receives 15% of the load.

Oi... my PC shop loaded it in for me. I can give you the name, but not the program itself.

Let me hunt for it... been a long time since I even looked at it.

When you choose to view its operation status, it shows a current load graph for each processor.

Here is the full title and readme minus the legal disclaimer mumbo-jumbo:

TY...:up: just about said what I was reading up on em...

from AMD:
Quote:
AMD Dual-Core Optimizer - The AMD Dual-Core Optimizer can help improve some PC gaming video performance by compensating for those applications that bypass the Windows API for timing by directly using the RDTSC (Read Time Stamp Counter) instruction. Applications that rely on RDTSC do not benefit from the logic in the operating system to properly account for the affect of power management mechanisms on the rate at which a processor core's Time Stamp Counter (TSC) is incremented. The AMD Dual-Core Optimizer helps to correct the resulting video performance effects or other incorrect timing effects that these applications may experience on dual-core processor systems, by periodically adjusting the core time-stamp-counters, so that they are synchronized.

A while back Letum posted this explanation of how TC tracking operates in SHIII. http://www.subsim.com/radioroom/show...10&postcount=6

I'm not sure where he got the info but it's one of the clearest explanations I've seen of why you see more at low TC than high TC. Simple computational expediency.

...Which leads us back to the answer that high TC reduces... and even eliminates aircraft attacks regardless of what we may try to do.

During the beta sessions for GWX 1.0 a little over a year ago, we did some testing with the airstrike.cfg file using elevated airstrike generation percentage values.

What we found was that though you do get a few air attacks at high TC... you are absolutley SWARMED by air attacks at low TC. (Dangerous file that is!)

Recommendation to all: NO TOUCHY THE AIRSTRIKE CEEFIGGY!!!:o VERY BAD JUJU THERE!:o BAD MEDICINE FOR YOU!:o

Hi Kpt Lehmann,

You've beem misled on what this app does. It doesn't "equalise" the load between each CPU, windows does that itself (and its not necessarily a good thing... look up "cache thrashing" on google to see what I mean.

Each CPU has a register which acts as a sort of time counter, but it measures processor cycles, not time. Power management and other things may change the clock frequency and this means the counter on each CPU on a multicore or multiprocesor system won't stay syncronised, differences will creep in.

Now some games and other apps use this time counter to measure elapsed time. This is really a bug, they shouldn't do this because one minute the program's code is running on one cpu, the next second the OS switches the code to a different CPU/Core and the program makes some assumptions based on what the time counter was a minute ago, and what is is now... but it never realises it isn't comparing the same time counter.

A program that has this bug may do many different things, from crash to have a very slow or unstable frame rate. This app was released by AMD (and only works on AMD systems) to try and keep the time counters syncronised between CPUs so badly written programs work properly.

I'm pretty sure SH3 doesn't have this bug, and unless you are running something that has this problem the app won't increase your framerates at all

Hope this clarifies things

I dont run over 512 myself anymore, which from experience still allows me to get reports on aircraft and still have time to either submerge or load the guns up...same with convoy reports
I did used to jump right into a patrol and head out to the patrol grid at full TC and always wondered why I wasn't getting any action....

Well, I'm also one of the lucky few who knows I'm not getting screwed over by my PC shop.

I've encountered no problems using the app with any game, and though its been awhile, they took the time to explain the optimizer to me. (twice... because I asked again at a later time) They push it on me.

Infact, the store I go to often chases me out of the door without charging me for many of the things that others are normally charged for.

Heck, they gave me a full brand new copy of Rainbow Six one day not to far back.

They get free stuff and pass it on to people they like.

No offense intended. I've been their customer for several years now for good reason.

They listen.:yep:

That being said, dual core processors were still fairly 'new-tech' when we built my current rig. I'll ask them about it in the next day or so here. If new info is available and it turns out to be negative... they'll be straight with me and recommend a course of action.

KeptinCranky 01-03-08 11:22 AM
Harr, all this rambling about high TC settings :nope: my first GWX beta test rig couldn't handle TC aboce 256x effectively, CPU too slow, and ramping it up beyond 1024x was right out, so I did most of it on 128x...it's the way to go, even across the atlantic all the way to the Carribean :yep:

this is also why I went to silly places like Liverpool and the Irish sea and still maintain that AM36 is a great hunting spot :up:

Has any modder tryed to slow the aircraft speed down.

I am 100% sure that slower aircraft will mean more aircraft spotted at high TC because
the "Jumps" they make will be smaller.
This is why we dont get the problem with cargo ships.

I rather suspect the GWX aircraft are faster, more realistic when fighting them, but it
makes the TC bug worse.

The ideal solution would be to have aircraft move at 30knots when not near the player,
but speed up to normal speed when in visual range. Alas, impossibe asaik.

Jimbuna 01-05-08 09:02 AM
The problem with the aircraft speed is, if you lower it they lose altitude and eventually crash.
