Multicore Patch?

[redeyemingo]

Will there be a patch to use all cores on a multicore cpu, like microsofts sp1 sp2 for FSX?

It is a planned feature, but there is no ETA. It's a massive job to re-write the engine to be multithreaded, so it's basically one of those things that they would like to do but it's no easy thing. This might get delayed to a completely new version of the engine, which means it would take a good while.

 

They will give the engine 64-bit native support first.

 

In the meantime, you can use Vista's and W7's good multicore managing features to boost your FPS immensely through the various affinity tools that are out there.

Hi,

By waiting the feature, u can use DCS Max -> http://forums.eagle.ru/showthread.php?t=39261&highlight=DCS+Max

[EtherealN]

No he can't, since he is using Windows XP.

[Feuerfalke]

Yes, he can.

 

But as with FSX, he won't benefit as much from it, as Vista/Win7-Users do.

[psycho]

exactly, he can but gain not lot of fps.

[EtherealN]

Yeah, that's what I mean - every test I've seen (though I did stop looking a month or so ago) has indicated that any affinity trick use in XP either gives you zero boost or something in the order of a few percent - where the "gain" would be within error margins. So in my opinion it would seem that from a pure performance/multicore perspective, there is no real point to running it in XP. (Whereas on Vista it can give really good gains that are definitely outside of error margins.)

 

If there's been ways found to get proper boosts (even if not as good as Vista's) with DCSMax in XP, then obviously I am mistaken and will have to retract my statement. I just haven't heard of anything such.

[redeyemingo]

Also read up on these tests and came to the conclusion it was not worth using affinity in XP, getting 35fps to 40fps using one core on my

Q6600 most of the time , I got a good cooler so i will wind her up to 3.2ghz to get some more FPS that way!:)

 

Cheers

Have you considered getting a Vista or W7 partition? As far as purchasing a new windows license I suppose one might as well wait for W7, but between the security gains and performance gains with DCS I don't really find reason to stay with XP.

OEm visat 64bit off new egg for $80.00, Worth every penny after i got a 30fps boost in DCS and all my other games look amazing

[redeyemingo]

I were under the impression from reading multiple threads that vista would slow down my fps because of the bigger over head for the OS,only reason I can see is direct X10 but comparison screenys do not make a compelling enough argument at the moment . I have windows 7 Beta on another machine I will make a partition on my gaming machine and compare FPS!

Sims Run

Black Shark

FSX Acceleration

XPLANE 9

fs2004

LOMAC

IL2 1946

Open Falcon 4.5

Falcon 4 Allied Force

7 G Beta

Tests I have seen with DCS:BS indicate a couple percent lower FPS with Vista before applying the affinity trick, compared to XP. When affinity is applied, I've seen boosts at 30-40% and up.

 

Basically, Vista and W7 have more things under the hood, so that will decrease performance, but they also have much more refined mechanisms for handing it's workload, which gives a boost. This is most noticeable in how it handles multicore processors and how it manages to use the extra core(s) to get you greatly increased performance even in applications that are not multithreaded (like DCS:BS).

 

In contrast, Windows XP has only patched-in multicore management to allow it to use multicore processors. But it's sort of like how almost any car can technically drive a rally, but it won't get as good results as a car that was built for rallying from the start.

 

EDIT:

If you want a compelling argument though, I'd say you should notice the fact that Windows XP is now on extended support. (Since April 14th.) From my understanding, that basically means that Microsoft will not lift a finger to keep the system current, but they will still offer paid support for users that need them. (Which is usually only interesting for commercial or industrial users.)

 

So pretty soon we'll see XP have the same problems as 98, 2000 etcetera in that while the old stuff still works, no thought is given to it as people create new standards and new applications and games. So while it will remain more effective on it's own from having less overhead internally, you can say that about 98 and 2000 as well - they have even less overhead. But just like they are pretty much abandoned, Microsoft is doing all it can to be able to drop XP entirely. (Hell, they're even making noices about wanting to drop Vista once W7 is released...)

Thanks EtherealN

 

 

Looks Like the way forward for me is to have a windows 7 Beta partion as well for now with Black Shark on it enjoy the Extra FPS for 2 months then wait for the release of Windows 7 (Back to 30 to 40 fps with xp for a couple of months waiting for windows 7 release! :mad:).

 

And an Over Clock to 3.0+Ghz as core temps at stock under full load is only 28c!

 

Had good experience with windows seven just hope Microsoft do not clutter it up before release!

 

 

Older Sims running at 90 to 110 fps on xp max settings

 

X Plane using all cores 40 to 90fps xp Max settings

 

Fsx using all cores 20 to 50 FPS Medium High Settings (should get a 30+% increase after an overclock!)

Patch 1.01 will just fix the affinity bug. That doesen't mean it will make DCS a multicore application. ED said in the future perhaps DCS will be optimized for multicore, meanwhile we'll just get the boost from Windows automatic core affinity managing, nothing more. If DCS was a true multicore application it will gain like 50% more fps going from 2 to 4 cores. Windows is capable of giving a very nice boost going from 1 to 2 cores, but from there to more cores perfomance boost is way lower.

 

For real multicore simulations check upcoming Rise of Flight or Oleg's Storm of War. That is the way to go, considering multicore CPU are the standard to get more powerful computers.

I am using vista 64:

- without dcs max I got 18 fps in cabin, with dcs max I get 29 fps.

[EtherealN]

Windows is capable of giving a very nice boost going from 1 to 2 cores, but from there to more cores perfomance boost is way lower.

 

Maximus_G showed us some pretty extensive tests with very interesting results that indicated a performance decrease (if memory serves) when moving from 2 to 4 cores on the i7.

 

The decrease (again, if memory serves, I have a link to the thread somewhere around here and will try to doublecheck) was within error margins though.
