Hi, I feel ashamed That I didn't saw your answer back in May ... I was so desesperate i let arma 3 down. With new update i try again and still crash ...

UP a month latter nothing has change I'm still crashing.

Is that possible for to downgrade Arma 3 to a version prior to DLC Tanks ? (I mean the exe + datas) So I can test If I crash on this previous version ?

Yep, just tested with dev branch 1.83 :

As expected, seems to work in 32 bit for this simple mission and the teammate mission (papi dans les orties V3).

NOTE : I crash also on several other mission that don't necesserally have boat, so it is not the fault of the boat, but since i can easily reproduce crash with this very simple vanilla mission, maybe it will help hunt the bug.

OK, I work on this issue all afternoon.
I get back to the original and first mission that make me crash : papi dans les orties V3

I created those tracker :

Yes it seems to related to mod.

Just did a memtest86, test 2 -5 - 8, 4 pass, no error.

I keep monitoring my PC during this period :

Ok I was alt-tabbing meanwhile, letting my arma3 running in background. Then I come back to arma (main menu) and chose virtual arsenal and then it crash ! I wasn't even trying to load a mission !

Some update : I manage to make this test mission work in 64 bit when not loading ACRE2 addon.

Note this crash in 64 bit. In 32 bit this do not crash.

I create a PBO of this test (still crashing everytime)

Ok another test that crash the game, at least 2 time in a row (i can test several time again if needed) :

Crystal disk is clean for both my SSD, and tried both of my 4GB ram alone, and crash every time too.

Thanks for your answer.

I want to add to, and I don't know if it's related, I also experienced a strage bug at the same time : Whenever I shot (whatever weapon i use) the fire sound is bearly audible like there is no sound ... And it is only for me firing, I can hear other fire sound from other people normal !

And now another error : 0x000000FF - Unknown

Tried in windowed mode it crash with a bad_module_error, and got this report : 0xC0000409 STATUS_STACK_BUFFER_OVERRUN
