I know what you are complaining about, but I cannot reproduce your problem, and I tried to. I don't even get the lag or out of memory errors that you get. All I am saying is that all points at a problem on your end, and that it has nothing to do with CUP.

Lag and Out of memory are totally normal ! the way i perform my stress test cause this and this is NOT what i complain about.

What you say, though, does not point at a problem with CUP. If you get lag with vanilla tanks and out of memory, that might be amplified by loaded addons. It still points at an issue with either Arma 3 itself, or your installation.

Damage and penetration values have been updated as of rWEAPONSSVN593. These values may still require fine adjustment to ensure they perform accurately.

Yeah did memtest86, windows memry check too, no error found. Swaping my pair of 4GB RAM (I have 2*4GB DDR3) to test only one of them at a time, but I still crash with one or the other.
I don't think it is a hardware issue, because on my test with popping lot of vanilla tank the game is very slow laggy but don't crash (until I get Out Of Memory error, witch is normal cause i'm limited by my ram + virtual memory).

Have seen something similar before. You might want to check your computers RAM with, for example memtest+ or something similar. It might be a hardware problem (althou it could be a software issue with OS, Arma or thirdparty programs aswell).

Yeah It seems to afflict me only ... don't know why, my teammate don't have any issue. Just me since Tank DLC ...

Tried it and I cannot reproduce it, neither any lag nor crash.

If you want here is my original ARMA 3 tracker : https://feedback.bistudio.com/T128171

Well as i said earlier :

It can be expected that the game crashes with many vehicles spawned and Arma starting to access pagefile etc. You most likely experience this only with other mods loaded, as those are loaded additionally by the game and thus producing a larger memory footprint of the game.

Submunition penetrators have been added as of rWEAPONSSVN586. The values still need fine-tuning for penetration and damage values to be correct.

I have added a few definitions in rWEAPONSSVN583. I believe them to be mostly correct, however there were a few that I was unsure about. (HESH rounds, APHE rounds, and the AGM-84s).
I have modelled HESH rounds as HE, APHE rounds as AP, and the AGM-84 as HEAT, however these may need to be changed.

This is a known problem since we haven't updated anything to the Tanks DLC yet. The last update was (IIRC) last October, so it would have come as a surprise if there was already Tank DLC stuff in it :)

Edited. MCC Causes problem when used in conjuction with CUP and Ares Achillies Expansion. when removed no issues occur

Just tried it, cannot reproduce. Works as expected here.

Leaving this in progress. Considering making a proper MATADOR. For now I replaced the model with the NLAW from vanilla.

Probably a corrupt download. Try to reinstall.
Also, there might be incompatibilities with other mods.

A friend more knowledgeable than I came to the same conclusion a couple hours ago. He added the info to my BIS ticket, hopefully they recognize their part this time.

	private_vec = vectordir _sh;
	private_no= 20 + random 7;
	_i=0;

Note, no space between the private and the var name, so the script errors out.
Broken on 1.80 and dev. IMHO, there is nothing for cup to do except wait for it to be fixed by BIS
