[REPORTED]High Memory Consumption

[sFalcon]

I only have 8GB of RAM and last night while hosting a simple server it was eating 7GB of RAM, upon saving and editing missions it would take literally 5 minutes to save any changes, because I was out of RAM, and therefore I'm out of fast processing ability :( so doing anything like saving missions etc always takes ages.

 

Temporary increase your pagefile to 20gb or so.. then you can play for some hours

[Stanomatic]

I was in the Options | Controls key setup for about two hours and DCS became real sluggish. I thought it froze, just took a long time for my mouse clicks to respond. I didn't look at the memory at the time. I fired DCS up again and when into Controls and watched the memory climb slowly. Version 1.5.1.4702

 

Looks like the problem is found while flying, encyclopedia, and Options | Controls page from what I have gathered reading through this thread.

Hi guys!

 

In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released.

So, in DCS... I think problem is that all models loaded stay stuck in the memory and every new one increases memory usage.

 

Check your normal memory usage in windows without DCS in performance monitor. I have G15 keyboard and display on it and Logitech Performance Monitor on that display.

 

Test it as I do:

 

- Ok, my Win7 & apps use 14% of 8GB RAM

- I start DCS and my ram jump on 21% usage and Video Memory (ctrl+pause) is 531.48

- Open Mission Editor............................................ RAM=27% Video memory=597.72

-- Open Encyclopedia (and look every model) with A-10A model (default).............. RAM=29% Video memory=902.39

...continue to browse all models (one by one) and see how they eat our memory:

So... only for browse encyclopedia my 8GB RAM is not enough. Models simple stuck in memory. Why they use memory if we don`t need them (we simple watch some other model after that)?

Same thing happens in missions too and servers crash, clients crash...

This is interesting.

I've seen similar behaviour,

 

When I was finished with a mission and thrown back to the menu screen, RAM would be up a little.

After doing like 5 missions my RAM usage for just sitting at the main menu doubled. And it kept doing that.

 

Same goes if you leave a server and join another.

 

During gameplay it takes a long time for me for it to actually crash because of it, but after a hour or so I will get stutters and lag.

[Gh0st007]

Yay I'm not the only one! 12Gb ram installed, when playing DCS 11.9Gb ram usage!

[Ocelottr]

Is there a flush command for clearing out VRAM in DCS?

[secret1962]

New update out. DCS 1.5.1.47285 Update 2

I don't see memory leak mentioned anywhere. Has it been fixed yet ? It's been 2 months... please...

Last update, better RAM usage, only the time to made some simple test. TF51D cold start up for ex., before update switching f11 view to see all airports increased VRAM to about 7000Mb, now only 3800Mb. Good job, i still don't test campaing or multiplayer.

[terence44]

Today we have updated DCS World Open Beta to Ver. 1.5.2 with the following primary changes:

 

Stability improvements

Continued work on Chinese localization and textures

New Mi-8MTV2 features like anti-icing “SECTION X” lamps and current heating for windows

Fixes and improvements to the L-39C.

F-86F improvements, including improved input for clock, canopy controls, rudder switch and fire warning system

MiG-15bis improvements, including: fixed marker activation over NDBs and adjusted G-suit performance

A-10C improvements, including fixes for no elevation data for init position, manually entered coordinates of init position not changing, and RWR switch being set to OFF when starting hot or from runway.

Corrected NDB and VOR positions.

Fixed memory leaks.

Updated Magic II and Super 530D performance.

Updated and corrected Encyclopedia.

 

"Fixed memory leaks." :v:

[droopy114]

Finger crossed

[secret1962]

It's 5 gb just in the lobby all over again.

 

5.50 gb...

 

6.00 gb..

 

Is this a joke ?

 

It's freezing all over the place. My GPU is like dying... worse performance

 

Unplayable... can't even start up with all these freezes.

 

20 fps at most and it keeps freezing... Please...

 

My pc is beginning to freeze all over the place.

 

Any head movement I make freezes the game.

 

Far from fixed.

Edited December 12, 2015 by secret1962

[Boberro]

16 GB here, 8 GB usage but not the highest settings.

[secret1962]

Memory leak is definitely still here.

 

And the GPU performance is worse or something.

 

Anything you do corresponds to a freeze. Look behind.. freeze. Open chat... freeze. Every 1-2 seconds you can see a small stutter/freeze. If you alt-tab everything starts freezing up. If you look at another player the fps drops by half or something AND FREEZES. It was definitely not this bad in 1.5.1.1

 

Ram usage keeps growing but slower than before.

Every 1 second you get a stutter. You can notice it when making a turn and I suggest you to try it. Sometimes the game will just go halt and you'll crash.. this was already present but is much worse since 1.5, and REALLY worse now in 1.5.2

 

Went back to menu... still 6 gb. So yeah it hasn't been fixed definitely.

Edited December 12, 2015 by secret1962

[bkthunder]

Still here for me as well. I have 8gb and it's still unplayable in MP. Crashed within 5 minutes of gameplay with around 6gb of ram usage.

Free flight server with 5 people in it.

You're not alone. 8gb here too.

Did you notice the stutters, freezes and fps drops worsening compared to 1.5.1.1 too ?

Then wait for the GA release and stop testing out Alpha or Beta products. Reporting a problem is one thing...complaining about beta products is altogether different.

yeah, actually in terms of smoothness and FPS every patch since the first release has been worse.

The initial 1.5 was very smooth, I had about 60 fps constantly and was very pleasantly surprised.

 

Now I barely get 35 fps in cockpit, and every time I turn the head I get freezes.

Big freeze every time I get to F2 view, and even bigger freeze in F3 when the plane is passing in front of the camera, I get about a 2-3 seconds freeze.

[xcom]

I can confirm, DCS ISRAEL server has been running for 34 hours straight, started with around 2/3 GB RAM now it is taking about 9GB, seems like most of the leak has been fixed, but there are still some remnants left.

[Anatoli-Kagari9]

One question,

 

this memory leak affects only the server side of the game, or does it plague even the client side, or the program used even in offline mode ?

[xcom]

server side/client side, same EXE.

So I do not think there should be any difference.

[terence44]

Hi, I have just made 30 hatreds of minute of flight in multiplayer and in L-39 (in 1.5.2.48726.137) and I am impressed, me had no annoying freeze, my RAM did not exceed 2,5 GB, while on the same server with less world I was in the later versions in easy 6 used GB of RAM, from time to time

 

I had a microphone-freeze and my RAM was reset in 400 Mb! :lol:

 

I know that a correction of the leaks of memory does not appear in the exchange log of the version 1.5.2.48726.137, but in any case during this flight it was the first time since I have 1.5 that I had no leak of memory . :)

 

I had also deactivate my antivirus (Avast free license) before launching my game, I do not know if that helped or not ....

 

In any case if it is good Eagle dynamic who corrected the problem, one thank you ! That finally restored me the envy to use DCS World !

 

Sorry for my bad English, and Merry Christmas everybody !

[bkthunder]

Unfortunately nothing has improved for me. Just tried on a free flight server.

I had 5 Gb filled before entering the cockpit.

Slowly kept adding up to more than 6.5 Gb and then crashed.

1.5.2 is out of open beta. Can I complain now ?

I still get 6 gb and over RAM usage and the game stutters everything both inside and outside the game. 5 gb JUST IN THE LOBBY. I'm not the only one here with this problem anyway. 8 gb. I think freezing the entire computer is a serious issue though.

[hansangb]

Yes you can! Hell, I'm trying to track down a weird DX11 problem when 1.2 went to 1.5GA!

 

EDIT: It wasn't the upgrade the 1.5 that created my problem. Tracking it down to an added USB card or Prepar3D.
