How To (Hopefully) Reduce Memory Leaks

[BlackShot]

I know a good amount of people know it already. For those who don't, this guide is for you. If you have been facing too many memory leaks recently - a.k.a. FPS drop, FPS lag, invisible items/people - we'll try to change your memory allocator. Just follow the simple instructions below.

1. Open your game launcher
2. Click 'Parameters'
3. Go to 'All Parameters' tab
4. Scroll down until you see 'Memory allocator' option
5. If unchecked, check it and select 'JEMalloc_bi' on the drop-down list
6. Launch your game and test your new settings



Hopefully changing your memory allocator is either gonna fix or reduce your memory leaks.

You're welcome!

Some of my friends were still facing memory leaks too often. I know this workaround has been *around* for a while now, but many people still don't know about this memory allocator stuff. So I thought it would be easier to send them a link with all the instructions instead of telling every single one of them what to do.

Alot of people see performance improvements/less memory leaks if they have no launch parameters, it helped alot with my memory leaks, used to get one after 30mins of playing..

After my visit to the prison yesterday I mem-leaked 5 times in 20 minutes. Have you been their recently?

i have 4gb video memory so I should set my memory limit to 4097?

If you're really talking about the video memory limit, yeah. I'd personally set it to 3996, so that way you can leave 100 MB for your operational system. Don't confuse it with the system memory limit though.

Never knew this existed, even after searching on how to fix this issue, or at least make it not as bad. I will be doing this when I am back home in couple of hours, hopefully this works, thank you for the nice guide.

This workaround was usually something very spoken of. But I personally haven't seen anything written anywhere. Hopefully more people will get to know about this. By the way, please let me know your results! You're welcome!

If I increase my resolution to 2560 x 1440 after approximately 1 hour of gameplay frames will drop to 5, character will do odd movements and it will not recover.  I have to shut down Arma and log back in for normal play.  No issues at 1920 x 1080.  Any suggestions other than gaming at 1080?  Sorry to hijack a post just seemed like you guys maybe able to help.

Thanks

That sounds like memory leak. Have you tried following the instructions at the main post?

[BSquare]

will do tonight.  Thanks for the help. Will let you know how this works out.

I have personally tweaked ingame settings, launcher parameters, different arma clients ect.

Still get the memory leaks, however the frequency of them drastically changed between the different available memory allocators.

Have you specifically tried JEMalloc before?

Yes, for me having no allocator is currently best.

JEMalloc gave me a high amount of mem leaks on CQC servers and lower fps on Asylum.

Both with and without i have the same amount of memory leaks on Asylum.

Thanks for the feedback. In my personal case, it seems like I'm getting less FPS on Asylum (nothing scary), but my memory leaks are basically gone now. Very rare to even face one in a day.

Yeah very strange issue in general.. 

Eitherway for the people that still experience memory leaks after trying this fix, also try the other allocators.

@BlackShot  12 hours of Asylum thru the past weekend using JEmalloc I experienced 0 mem leaks.  Finally able to enjoy my new monitor at 2560 x 1440 144mhz.  

Thank you, thank you!

It drops FPS a little bit, compared to other allocators. But it's either that or constant memory leaks every single day.

worked out very well for me

Good to hear!

that was very helpful i'm out of likes I will give you some tmr

UPDATE: This method might be out of date because of Arma's new patch, where they introduced Arma 64 bit. Just by updating your game to that version, 64 bit, you are likely not to encounter memory leaks anymore.
