SH5 performance improvement >>>>>>>>>>>
 

Copied from the readme
Enabling 3GB switch on Windows XP or Windows Vista
Advanced users may know that the virtual address space of processes and applications is still limited to 2 GB unless the /3GB switch is used. Activating this option in Windows greatly enhance Silent Hunter 5 performance.
WARNING IF YOU STUFF IT UP YOU WILL HAVE TO REFORMAT YOUR COMPUTER

I will try. Since i play SH5 i have performance problems with the game (stuttering in external view and jelly water).

My specs:

Intel P55
i7 860 @3.15GHz SMT on
8 GB DDR3 1400MHz
2xHDD SATAII non raid
AMD HD58701GB
1920x1200
Win7 HP 64 bit

Grateful for any tips.

edit: With 64 bit windows i don't need to do this?

The jelly water is a hardcoced water rendering issue i would say . I dont think it has anything to do with your hardware . No need for the bootini request with your system . No idea what would be causing the stuttering . I have an asus eah5870 version 2 card and no stuttering at all . 100fps outside and 120 fps inside sub . No stuttering at all . Although i have an i5 cpu with just 4 cores and not i7 with 4 cores and 4 virtual cores .

Can u show us the steps on how to do it?

If i had the stuttering i would tend to think it may be some sort of irq conflict ? I would move the graphics card to a diffrent slot , if it is in a pcie16x slot maybe move it to a pcie8x slot and see how that goes . You will only lose a couple of fps .

Its a 64 bit os , no need to do it .

Another thing with the stutters , go into ccc and set the AA to performance and see how that goes . If that doesnt work try down clocking the card in overdrive to 800/1100 .

Hi sober, thank you for the reply.

I want to read the boards manual because i don't know the specs of the second peg port now. It's the Gigabyte GA-P55-UD3. Also i can remove the audio recording card and second networking card. SMT off as an option. And will look in bios the turbo mode settings.


Good idea. I will try this tommorow. 10.5. AA is already set to performance.

I have a corei7 920 running 3.4ghz and a gtx295.
I get the stuttering too and I have to run alternate frame rendering 2 in the drivers or sh5 only uses 1 gpu.
I have it running 1920x1200 with all settings on except shadows off.
Shadows seem to make it really bad.
I hope a sli profile is released but I doubt it.

only if the programs .exe has it already enabled. I dont have sh5 installed right now but i use a program called CFFexplorer to change that.

All you do is install CFFexplorer,
right click on the SH5.exe,
choose "open with CFF explorer",
then on the left look for "File Header",
click it,
then on the right click "click here" next to characteristics
then a box opens up with checkboxes,
if you see a check next to "App can handle >2GB address space" then it is enabled. If not checkd, check it, close the box, and File--> save

make a backup if ur skurrd.

Many programs do not have it on by default. Maybe games, but i always check to make sure its enabled. (usually isnt)

I tried this. Seems to be checked (enabled) by default.

Thank you for the tip.

be careful if you have a weak Power supply or bad cooling though :o

:yeah:

he said down clocking, which should be safe for temps/PSU right? Sometimes stuttering is caused by a high temp video card. You arent hurting anything, i dont think, but once a card reaches its upper range of temp, i think it cuts back performance.

Its summer guys protect your PCs and keep them cool. Underclock if necessary. I try to keep my GPU below 80c, usually by forcing the fans to 65% while i game.

A good tip with down clocking. I set the values to 800 and 1100 and a much smoother playing now.

Thanks again sober.
