So, I run a little fledgling community playing Arma. I don't claim to be good at mission editing, infact I do it all on the fly with Zeus and VTS. My latest bugbear was the AI, and I did a test where I ran Firefight Improvement and ASR AI3 and between them, the AI were fantastic. They worked as a cohesive army as well as, at a squad level, were tactically lethal. However, I realized after players joined that it tanked our FPS. In Zeus it was fine, but as soon as I jumped out into my characters shoes, my FPS was awful, the VTS client was unbelievably laggy and everyone could barely play. This was, I assume, due to the AI pathfinding and waypointing.

Is there a way to get around this issue? These AI are superb, and I'd love to continue using them, but not at the behest of all our collective FPS.

What you need is something to cache the units so they dont showup til your
within range of them, something like EOS does.
IDK if this could help you but this:

A revisited version of the simpleCache script included in AI Spawn Script Pack which does not require to execute any controlled militarize and fillHouse script before.

There is another caching script which i had used in Arma2Co which worked perfect, but Im not sure if it will work in Arma3:

hope that helps.

Welcome to the Armaholic forums btw :)

Thanks. I don't tend to post in Arma forums because I know jack all about scripting or editing. I make my missions using VTS and Zeus, so it's kinda pathetic in comparison to most people.

No worries, everyone plays the game different, and has their own interests, its whatever floats your boat.
