i guess you referring to this one?

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...
