*sigh*
That's the kind of topic like those over on the Arch forums shen people try to run Arch on 10+ year old hardware: Get it - your hardware is too old - upgrade your hardware!
A3 always was and sometimes still is the Crysis of the 2010s: It is unoptimized as hell to cause even beefy hardware to perform like crap.
An example: I ran a R9 290X - one of the high-end cards of its time - got roughly 30 fps ob mid settings - upgraded to a R570 - still only managed to get unstable 60 - it takes a freaking xt 7700 and a 5600 to get me stable 90 fps on high - with cranking to very high tanks me back to below - and all that on just 1080p!
Same goes with loading times: As I'm on Linux and ZFS most is cached into RAM - but it still forever on first start to load it all. And A3 is like gta V o that matter: big simple archives to aid with high sequential reads. Ever played killing floor 2 with all its billion of 1kb assets? Enable ANY anti virus on windows and your back at the 80s when we used tape with our C64

Point is: Some games are designed and hence run like ass - unfortinately A3 is one of them - all you can do is compensate with beefy hardware. You want to play with a metric ton of mods - cool - use a system that is able to load all that crap in time! This request is like dealing with flu by drownibg painkillers with liquir - it doesn't solve the root cause: bad optimization on bad hardware

my recommendation: figure out which mods take all the time up to load so slow and just don't use them

@Dwarden is it possible?

BattlEye would need to add it on their end.
Probably into their existing BE server config.

There was a problem with sending BE messages, they would get dropped if you had packet loss.
Last week on prof/dev we changed them to be retried on packet loss. That should fix packet loss related BE timeouts.

It was never fixed for me, and for players on my server.
I have an i9 with 32 Gb RAM, RTX 3080 Ti and a 1 Tb NVMe drive and another 2 Tb NVMe drive, but it is supposed to work with anything in the minimum requeriments or above.
And i tried many hosting ways, at home, game server, cloud and dedicated (Linux and Windows).
My situation is or I turn BE off, or no Arma server.

Also it has nothing to do with long delay on game start, players are kicked in game, walking and shoting, some time after they join the server, and it's no filters kick, i use no filters.

Same thing in AMP Linux Panel forum: AMP Panel for Linux is wonderful, but for Arma 3 it needs BE to work correctly, so... no Arma server because BE kicks everyone with Query Timedout. Many users in the forum are asking for a solution and AMP devs says Arma 3 devs need to make Arma 3 RCON free from BattlDead (they not even consider fixing BE). This will make RCON less secure? I don't know, but this is what they say.

I will love to be free from BK (BatllKicker) forever (hackers do less harm).
Search for problems with BE, you will find many, many topics, in many games, everyone with the same problem, 100 ways to solve it and none works. Even ChatGPT apologize when you ask for help on that.

I know nothing about Reforger, like i knew nothing about Arma 3 some years after its release (i was in Arma 2), but something say me it don't use BE and Arma 4 will don't use it too, and no other game in world will use BE anymore.

But for sure, all i sayd can be wrong and the problem is my low IQ, no will to live, arrogance, lack of suitability, moral, and lack of valor as a human, who knows?

I'm Donnovan, BattlEye is amazing.
Ban me please!
