Could you attach .RPT file to this ticket? It would help us pin point the issue of your problem.

You can find .RPT files here C:\Users\<Name>\AppData\Local\Arma 3\

Thank you

done and done :) i really hope i get FPS back somehow. i almost tought my graphic card, memorys, mother board or hard disk was broken. but i saw there is same issues some players

Hello,

It seems you have custom allocator running which could be the source of your problems. Try removing the -malloc=tbbmalloc line from your Target field in your Arma .exe properties.

sorry it doesent work.

still crashes in few mins

We need crash dump files from this folder to analyze your problem.
C:\Users\<Name>\AppData\Local\Arma 3\
Can you upload somewhere in winrar package, please?

How to find correct crashdump file:
Try to make the crash happen
Look into crashdump folder
Upload crashdump with latest date in name (crashdump is rpt + bidmp + mdmp file with same name). Please try to provide as many crashdumps as possible, it helps us investigating the problem in a big way.

ok. i hope these was you asked

Yes, those are the files i was looking for. Unfortunately you are running either mods or custom allocator. Could you please run the game vanilla without any mods or custom allocators and try to reproduce the crash?

Thank you very much.

seems game wont crash when im single player anymore, but its reeeeeeally low FPS. i tried multiplayer and there its impossible to play 1-2 fps and in singleplayer its around 10 fps

could you please verify your game files via Steam?
