Is there any way to optimze the pluging or a update to something newer?

What do you want to optimize ? It does almost nothing. There is almost no computation in it.

I have to update it anyway, because there is a new state added.

so i was talking to my server host and he said that these plugins where causing a performance issue on the server for frames rates my server frame rate is about 30 to 40 and im trying to make tweaks to it to see how i can get it better with out removing the plugins. if u have an advise i would greatly apprecatice since i have only been and owner for two weeks so im learning and i appreciate all the work u devs do man

Usage time is because of triggers (targeting for example), that cannot be avoided but don't consume that much when called. They are just called a LOT of times.

Did you use to have better framerate ? Maybe the server you are running isn't scaled enough for the map size you have (the major consumption).

i seem to have lowered there pop from 25 to 15 and that helpped a lot  plus i been making few other tweaks but ok i was just wondering and whats the update about if u dont mind filling me in if u can anything new.

Yeah I'd gonna tell you to lower the population too, as it's a big factor.

It's about repairing the custom AI, or completely remove it, I don't know. Now that it's fixed by Facepunch, maybe I dont need to rebuild it.

haha hey prob saved u a punch of work and yea if the 15 dont work ill lower to 10 i just like them on there there cool lol
