Is there any idea why am I got lag when I i put the robot on the map ?
I installed AAI mods , when I added a AI into the robot than its fine, but some how its lag again when I take AI out. I dont know why, I try into a new save than its fine again.
do you know any reason why its happen like that ? thank you ...

No I don't know the reason but I also don't know how the AAI mod works. Could you give me the names of the relevant AAI mods so that I can try for myself?

as soon as i put down the dreadnought my fps dies. any reason why that may be the case?

Probably because you have a weak PC. My script checks every tick if any dreadnought is moving. That's normally 60 times per second.

Edit:
I just tested it on a busy map of mine. 20 UPS XD
I always tested on new maps that's why I never noticed.
I'll try to adjust the script.

For now you can use the startup option to disable it.

oh....thank you so much , save my SAVE (MAP) XDD. thank you so much

I used all of AAI's mods

yeah disabling the walking sound in start up options does fix it, thanks

I pushed an update where you should be able to enable it while having normal fps. Could you try that? So far I've not heard negative feedback, it should work now.
