Optimal RAM requirements for SH5 ?

[Adriatico]

I would like to know what is optimal RAM level for SH5 (fully moded)... ?

With my IntelDual 8400 / 4G RAM / HD5870 under Win7 64 I have significant FPS drop - as soon as I approach Kiel or some other port.

What is your experience with 4G, 6G or 8G...of RAM?

(Maybe it is simply lack of CPU optimisation in engine...)

I've got a Core i7 and 6GB of DDR3 and I still lag a bit near harbors, especially with mods running.

I wouldn't use anything less than 6GB on a machine anymore though. I keep meaning to upgrade to 8-12, but I'm lazy and cheap. heh

Thanks kylania,
It seems that in Win7 64 - I am outsider with 4G of RAM...

I was wondering if SH5 is 32bit or 64bit appliacation... and does it uses QuadCore CPU ?

[Jan Kyster]

Of course it's 32-bit...

I don't own it (at least not until the you-know-what is removed by you-know-who), but it have to be 32-bit.

Btw. running it under Win7 guarantees a balanced load on multi-cores CPUs and if you want SH5 to use more than the 32-bit programs restricted 2GB RAM, go ahead with the Large Address Aware-bit setting.

Made a big difference in SH4 and may indeed remove the lag Kylania is experiencing...

Actually, when I've tried to activate the Large Address Aware tag in the past, it's told me that it already uses more than 2gig, so afaik it's a 64bit app.

@OP - I've got 4g DDR3 and Win 7. Try turning harbour details down in the in-game menu, or particle effects in the same place. Failing that, use D3D antilag to improve your overall framerate.

With what application?

If you use the app from the above link, you may find something else...

So system requirement is Windows 64-bit? Find that hard to believe...


Btw. switching to a mouse with higher resolution (dpi) solved my lag issues

[Adriatico]

Actually, it is not a lag problem... but overall FPS drop problem.

I use a lag-cure from the 1st campaign...

Are there any reliable info: how much RAM this sim addresses ? How many CPU cores it uses ?

Is it another "military secret" of Ubi... ?

Yup, that's the app I use (used it for SH4 to make that LAA). When I point it to the SH5.exe, the box is already checked. I was surprised too, so it probably doesn't mean it's a 64 bit app, rather that Win7 recognises it as something that can use Large Address Aware and applies it automatically.

I have 8 Gb RAM, CoreI5, 1 Gb Nvidia 520, and I have drops of FPS in dense scenaries. I use 4Gb patch over SH5. exe.

I drop as well near harbors. That can't be avoided. The question is "where does it drop to?"

If it drops to 18-24 FPS as it did on my old rig, then that can be pretty distracting. But if it "drops" to about 50 FPS during Kiel rush hour (which it does on my new rig), then it really doesn't matter in my opinion, as our eyes are "wired" to about 30FPS.

What I found was that the "bottleneck" for SH5 appears to be the CPU load. My old rig, an AMD Phenom 9850 BE @2.5GHz didn't see hardly any improvement at all in "tough areas" like harbors when I upgraded my GPU from an nVidia 260 to a 570, which surprised me a bit. Never had a chance to try out upping my RAM from 4Gb to 8Gb on that one, but I'm not sure that would have made much of a difference as the HDD LED wasn't really flashing that much near harbors.

But upgrading to my current rig (in my sig), which was mainly a CPU upgrade, made a world of difference, so I suspect it's mainly CPU load keeping the FPS's down.
