Quad Core vs Dual Core. Which performs better in BS?

[815TooCooL]

BS : best multi-core support game of the year.

(Note: NOT intended by devs.)

Devs, did you think it was ok? It runs just horrible without affinity trick.

But it runs so silky with affinity trick and I'm so satisfied with the game so don't bother. :D

It is BEST flight sim, ever. No more IL-2, no more flight simulator.

Thank you devs.

 

Anyhow, let me ask you a question.

Someone said his quad core gets 60~130 fps with affinity trick, whoa. When he didn't do affinity trick, it was at 15~30 fps in ground.

 

Usually, we dual-core users got similar on-the-ground-fps, 15~30 fps.

And it jumps up to 40~60(vsync considered, actual fps definitely not going over 60) when affinity check is turned on then it runs like baby. No more trackir choppiness.

 

Looking at quad-core user's comment, it seems BS benefits from quad-core so the frame rate goes up, say, 50% better than dual-core.

 

I'm considering quad-core CPU from current E8500 dual core.

I'm at 3.16 ghz but if i go quad it becomes 2.8ghz or so, less core speed.

 

Can BS benefit from even 4 cores? it just seems to me that it's about core numbers, not core speed.

 

Additional core effect was so dramatic that it still tempts me to add more cores. Really wonder how BS would look like with Core i7.

 

I just hope devs don't mess up affinity effect with upcoming patch. :D

Slightly of track and isn't answering your question but FYI your E8500 is generally known as one of the best Intel cpu's for over clocking. Even with the std cooler mine is running silky smooth at 3.8ghz and not hitting 60deg under load. With aftermarket cooling most are running 4-4.2 ghz. maybe you should try a little overclocking up to 3.8 to be safe and you should get about 15-25% fps increase. Only increase the fsb by 16ish at a time and monitor it with speedfan program then increase again etc. :) Sure a lot cheaper for the short term till the quads come down in price.

The grass is always greener - I was considering the exact opposite - Q6600 to an E8500 :)

 

Nothing scientific, but when initially messing with the affinity trick, I did not notice a difference between enabling 2 vs 4 cores.

 

I agree with Macka that you should overclock that 8500. My gut says 3.8 - 4.1 Ghz on an E8500 will outperform 3.2 on a C2Q.

Just got a quadcore. Whats the affinity trick?

[Flanker15]

You can set the affinity to use all of a multicore processor in DCS, but it only works in Vista (due to an interesting coincidence in how Vista manges cores). This is unintentional on the devs part but may or may not give you a boost in performance. Unless you don't play any other game or do anything else with your comp, it's probably not worth upgrading to the horror of Vista (it makes DCS run better but will make everything else run worse and drive you insane, as it did for me until reinstalled XP!).

 

I eagerly await true multi-core support, which will give a larger performance boost to all OS's.

 

If you have Vista and want to try it, start the game then alt-tab out and go to the process explorer. There is an option to set the core affinaty for processes.

[theox]

Hmm, seems I can do this in XP as well.

[Flanker15]

You can do it but it won't give you any boost, atleast no one has reported a boost with XP yet.

yep. BS is the first application that made me think to go for Vista.

I cant help hoping ED to release patch that gives affinity boost for XP

That's correct for my PC. I already had a dual boot setup. XP & Vista64. I initially installed DCS BS on XP (because every other sim/game works much better on XP for me). I tried the affinity trick and didn't notice any gain........ so after reading many post here, I said what the heck, let me try it on Vista. So I installed it and was amazed at how much SMOOTHER the whole thing played! (no micro stutters). Then I enabled all four cores and got a HUGE boost in fps! So for me, I now have some use for vista..........BLACKSHARK. I was so excited, I rebooted into XP and uninstalled BS without de-activating it :( But overall, I'm very happy with this. Just wish I had more time to devote to my hobby :)

 

I still can't get over how great this sim is! I got the russian version and was happy to get the English version and can't wait to get my hands on that printed manual.

[redtail]

One thing I forgot to mention. I turned off aero (think thats what it's called) and all of the un-needed backround apps in vista.......clocks, callenders, pretty desktop themes and all that nonsense. Just give me the barebones OS not a pretty one! I want the fastest performance i can get......... It loads up faster now also :)

[815TooCooL]

I'm a PC and I even like Vista now thanks to BS.

Oh, I'm serious. :D

[tarball]

False

[McVittees]

False

 

Agreed. The bashing of Vista is boring. The only thing against it is you need a decent spec system, but if you've got one then it's invisible and for me works better than XP in many little, but noticable, ways. Really, Vista is a non-issue 99% of the time. The fact BS runs silkily smooth with multiple threads is an unexpected icing on the cake.:thumbup:

[Nate--IRL--]

Dammit!!! Don't make me install Vista again!!! :)

 

I've held out this long with XP, but it's tempting!

Just ordered Vista Ultimate from Amazon.......Post-Xmas present to me from me :D

As redtail mentioned earlier in this thread, you will get the most from Vista and your gaming experience if you turn off some things in Vista to game.

The way I do this is 1st turn off the siddebar ( you can always turn it back on after your done).

Then right click your games .exe file ( for blackshark this is the DCS.exe, not the launcher.exe), right click it and check the boxes to run as administrator, and Disable Desktop Composition. This latter entry turns off the Aero themes and all the eye candy items when your blackshark game starts giving you much of your systems power back for gaming. The aero theme and all the eye candy reactivates automatically once you exit the game too.

Hope this helps those stepping into Vista for gaming.

[AlphaInfinity]

I ran BS on my Dell e1705 with the core duo and a 7900GS card on XP and Vista.

 

Vista does seem to run the game smoother for me but only after I turned off Aero and went back to the windows classic desktop. I also upgraded the laptop to 4 Gigs of ram. The OS only sees 3 because it is a 32 bit, but overall, vista seemed to run the game better.

 

I am putting together my new Corei7 machine this weekend and I will be installing vista ultimate 64bit. In terms of the dual core vs quad core argument, I am not sure that the question is right. I believe that Black Shark really will perform better on a faster processor, not neccesarily a processor that has dual cores vs a true quad core processor like the i7 or a dual dual core like the Q6 series.

hi, can you point me in the direction of the exe file? I can only the launcher exe and not the dcs.exe file?

 

thanks:helpsmilie:

[Flanker15]

False

It was true when I had it about half a year ago, it wouldn't run most of my games (the older ones), took a huge chunk out of my performance and basically said "I don't think you should do that" every 10 seconds.

I think the last straw was when it basically went: "Sorry Dave I can't let you do that" when I tried to run an unverrified program.

I might give it another shot if the UAC and DRM have been removed (have they)? Might aswell wait for Windows 7 though.

 

I'll probably try duel booting it for BS though.

[xell]

The UAC is very easy to turn off - usually the stuff that annoys most people in regards to Vista. (win-r, enter msconfig, go to the tools tab and turn off UAC).

 

I usually have great experience with vista nowadays. Unless i want to copy files. grr. :)

[815TooCooL]

No tweaks needed.

Only you need is just turning off the UAC.

All other gimmicks do not affect game performance that much in recent systems.

[uhoh7]

I'm also happy with vista ultimate.

 

Never built a vista machine before this---much better than i expected.

 

Runs many old programs fine---even office 2k

 

It will boot in 30 seconds or less--fastest boot and shut down i've ever seen on any machine.

 

I like aero, but will try the setting mentioned above to disable in gam play.

 

running 2560x1600 on 30" samsumg----it plays well.

[cucu666]

=815=TooCooL, you can see my PC below, and BS get the same performace with 2 or 4 cores.

No one of the games and apps that I had probe, had taken more than 60 % of core use.

Yes, I know I've PC for 5 years.

If you only fly simulators, don't buy a quad core. But if you love Call of Duty too, please buyit.

[Wolf Rider]

Hi

Just bought the sim and can only say, Well Done.

 

I am at a bit of a loss though... I read of having to manually set Affinity for the dual/ quad core precessors. I checked on my Vista install to find all four cores were already ticked by default. :unsure:

[815TooCooL]

Finally, kind of an answer what I was looking for!!

Thank you, cucu666.

 

Oh, I don't like Call of duty. :)

I keep coming back to flight simulation.
