**** Performance fix!!! ****

Disable CPU Parking for multicore users!

See here:

http://www.coderbag.com/Programming-C/Disable-CPU-Core-Parking-Utility

Restart your PC after and try the game out again.

My FPS went up by 30 for most of the sections and atleast 20 for all. I have an I7 2600K by the way.

Everything feels so much smoother now. Can other people try and provide me with feedback please?

[SamCookiez 1]

I know when you go onto a server with 100+ ping the FPS slowly drops with the more people joining, is this a fix for that also?

[Tiglet 10]

Sorry haven't tried that because I've only joined servers < 50 ping for me. Maybe you should try it.

I had cores unparked since the Alpha beggining, so i dont know what does it change but the performance is still bad.

I've never been able to get this utility to work for some reason.

[SPARTdAN 10]

Is this just an Intel thing or does it relate to AMD?

[MavericK96 0]

Does nothing. Tried the same thing for ArmA 2 and it did nothing as well. My guess is this "issue" does not affect that many users.

[zimms 22]

For many/most people this won't do much I guess. As long as you have set your power settings to high performance, parking shouldn't really be an issue.

[Droikka 1]

Unparking cores does 0 things for performance as the game utilizes only two cores properly. You can set core affinity to 2 with A3 and you lose 0 fps.

Wait for the developers to optimize the game.

I would if they actually acknowledged this issue in SITREP, "known issues list" or simply reply on feedback tracker http://feedback.arma3.com/view.php?id=716&nbn=138#bugnotes

[Silent_Thunder 1]

The only way this will help is if you have a Bulldozer processor, as core parking is notoriously broken on those.

[chrisb 196]

@zimms is right, always set to 'High Performance', also visual effects in win7 I have set to 'Performance' as well. Most gaming pc's I would think are aimed at the game and not how good the OS looks or its background stuff..

The OP's idea may help for 6 or 8 core machines that are experiencing problems though, fps wise, maybe worth looking at.

This works fine. But if your OC, and set all your cores to the same speed (turbo off) its not nessesary. C-states and EIST off... HT off.

Have more than four cores? turn off the "extra" cores. MS will always try to spread the load around between the cores... That will mess you up. Then when a slower (bring up the map?) time in the game ,Intel will (along with MS trying to keep the cores equal) lower/or turn off a core(s), but will it be the right one(s)? Big frame drop/stutter, and or a constant low FPS do too the load balance.... If you dont OC use Corepark on Intel. More than 4 cores is a waste. And on AMD the 6 cores can be a issue. Only use 4, but which 4 to use? You can test that out.

I'm running a Dell XPS 17 Windows 8 Pro, and even with high performance, my CPUs still park.

[TEAMKILLER 1]

Thanks man! Worked good for me.

[Fuse 1]

I see this fix mentioned at least once per new game. I have yet to see it actually do anything (though I hear it may actually help if you've got a laptop with all the power-saving crap on?).

The massive issue tracker for the low performance/low utilization issue has been "assigned" so I guess we can hope they are looking into it seriously.

Making Parking Options Show in the Windows Power Options

[MaxiM_PL 1]

I hoped against all hopes that unparking CPUs would give me some performance boost. Alas, the only difference is that CPU consumption is distributed more evenly, but the overall usage stays at about ~30%, which is the same as with parked CPUs. Same thing with ArmA II and TOH. All BI games leave ~70% of my CPU and about ~60% of my GPU *unused*. Such a waste of processing power... ArmA games just refuse to take advantage of my PC.

You should probably give credit where it's due, bro.

Glad to see it's working for some people! Need to try it out myself.

Making Parking Options Show in the Windows Power Options

Don't need software, but you link software. I've tried that program. You have to set that "show in the windows power options" via the software. However, once I do that, I can't edit the "processor performance core parking min cores" option. and, when I do, what do i set it to?

[qbert 10]

I've had my cores unparked since a month ago when I got into Planetside 2, which it actually did help for. I can't comment on the performance increase in Arma though, I'd assume since it doesn't use multiple cores it wouldn't matter.

[magicool 10]

have my CPU unparked since release of Planetside 2 because this was claimed to be a fix for it aswell and I have problem of low performance aswell so obviously this is not a fix
