My ARMA 3 works with 120 FPS in ULTRA , but when I installed the MOD alive my FPS dropped to 30 , why?

Need more information than that... was that after joining a server? If so how many people were on it, how many ai were spawned, how many vehicles, etc...

Was it just at the main menu? Blank map in the editor? Did you restart your computer and it was still dropped to 30 when repeating the situation?

ALiVE will definitely drop the frames a bit. Just an FYI.

We need more details in order to help you out. i.e...

• Is this on a dedicated box?
• How many AI did you spawn?
• etc.

Most responsible for FPS is Virtual AI module setup. For dedicated server the best idea is 900m radius and 15 unit spawned at once.
