Memory Leak, 3 FPS, GameCrash


Since some people found out that the recent problems (crashing and stuff) can be fixed (or least help to dont crash early) with the maxMem parameter...

i may have found a fix...

in your arma sync check the box malloc and go for JEMalloc_BI then make the max memory to 2047.

not tested in MP but my editor seems fine now

In regards to Max Mem, i noticed they have changed the settings for it so
now i am running @ 3071 to see if it stops my 3fps bug aswell.

  • 32-bit Windows + 32-bit game: 2047
  • 64-bit Windows + 32-bit game: 3071

Just add it to the additional parameters.
Spoiler


...We should start to collect some infos about which settings people are using.
Maybe we can pinpoint some workarounds and get something like recommended settings that everyone should atleast use

Please use the following Template:

    -nosplash
    -enableht
    -hugepages

PS: I know that the MaxMem value Ive set is unnecessary high and it does not actually assign that amount.....

reV would you still have that previous link from the BI devs, re memory allocators.  I seem to recall that they no longer recommend using any

i guess you  referring to this one? https://dev.arma3.com/post/sitrep-00177

One of the recent Dev-Branch changelog entries informs the players about the removal of certain memory allocators. After a broader discussion within the programming team, we have decided to discontinue support of several memory allocators from the game distribution on Steam. These (TCMalloc_bi, NedMalloc_bi, JEMalloc_bi, tbb3malloc_bi) were not loaded to the game by default; players needed to use a special start-up parameter (-malloc=<string>). The reason we decided for this approach is rather pragmatic: we simply could not support all of the allocators properly and guarantee Arma 3's stability on other than the default allocators (tbb4malloc_bi, JEMalloc_bi). While the game is still able to load any allocator it is commanded to via the start-up parameter, the clarity of what we officially support and what is an experimental (and potentially unstable) solution will hopefully prove beneficial both for player experience on the one side and issue solving by the developers on the other side.

anyways, fred41's tbbmalloc isnt developed anymore and he deleted everything from his github.
there is a guy called _blub on the biforums that is developing a new allocator, and it looks pretty promising so far: https://forums.bistudio.com/topic/19181 ... or-for-a3/

i tested the tbb and xtbb as some of the vanilla ones and ill get a slightly increase of fps while using tbb over xtbb,
and when i tested the default ones i was pretty disappointed, some crashes and usual lower fps.
additonally since the largepage flag isnt working anymore (it got removed from windows 7 sometime ago) and i dont run the game as admin so i dont have the benefits of large paging allocations, but i still have better perfromance with tbb. (maybe some mix of placebo effect and bad timing regarding results :))
when 64bit will be released they wont work anymore though...

as the devs said, they will drop support of the other allocators that got shipped with arma for now
and will only focus on the tbb4 and JE allocator in the future

when you feel like JEMalloc_BI is working better for you than stay on JE.
cant really tell whats the diffrence there, but the most custom allocators ive seen were based on tbb3/4

ill try out the newer CMA (Community Memory Allocator) from _blub this weekend and see how it goes...

@Jdownward. Can you stick up your settings using reV's template, please: equally, anyone else, who (or not) found success using the details in this thread.

My head is on a swivel, I just left the WD-40 at home.
