what is headless client?

[kgino1045 12]

I don't get it what this function do it :(

In shortest way:

1. When running dedicated server it usually utilizes 30%-40% of CPU core/cores power (depends of mission) leaving 40-50% no utilized power,

2. Headless client = client connected (like player do) to dedicated server, it takes AIs calculation, so free CPU power is utilized,

3. It gives better Server FPS = more AIs,

4. Mission must be designed to get headless client working,

So headless client make server to clean and good performance?!

Thanks Pawel :)

What happens if I set up a hc and play a mission which is not designed to support a hc?

I would like to set up a hc but we play a lot of pvp missions or smaller coop missions also which doesn't need/support a hc.

You cannot setup HC on a mission that does not support HC. So... Nothing happens...

HC ai play as they were coded to perform. It's a whole other ai when freed from server calculations.

They will flank your position once engaged.

Here's a youtube vid, "ArmA 3 Alpha: Headless Client AI performance test with 500 AI!":

Seems like a complex workaround which only works for specially designed missions. Why can't the dedi server just use all the available CPU to avoid the need for this?

Interesting question :)

Whats funny is the word itself always made me think that headless client was some bug in the game that you would see,.. well a headless client,

would it not make more sense to name it low core client or something of the like?

I think that's where they are getting the term from.

Apologies for a dumb question, but does a headless client run on the same processor as the server, ie utilising an un-used core, or is a separate machine required ? Probably like many I have enough old half decent parts lying around to build a small machine which could offload the AI workload in SP games (assuming they are structured to use HC). I guess licensing is also a factor with a separate license for the game required for a separate machine ?

The ideal situation would be the availability of a low/no cost headless client license running on a local second machine without a full UI, with the Arma server engine modified somehow so that a connected HC system would be automatically used for the AI calculations without having to customise the missions. I am not modernly technical, so am probably smoking the wrong stuff again . . . back to the bath with the national ladies volleyball team. :) . Thats never going to happen either.
