Weird Pausing/Stuttering Lag Only During Star Fort Sieges

So I've been playing NTW for a while now, and never had any problem. Campaign map is smooth, and battles are smooth. I play everything on "High" with all of the special effects except AA and SSAO.

Anyways, in the past couple days I had 2 big siege battles against star forts. I noticed my troops are moving in a weird stuttering speed with their legs, and everything else seems to have a pausing/stutter sensation.

If I reduce every single graphic option to low, it doesn't change one bit. I get reduced graphic quality, but still the same stuttery speed.

Is this a known problem and is there a way to fix it?

UPDATE:

While playing my latest star fort siege and experiencing that major stutter, all of a sudden it fixed itself half way into the battle. This is with my current High settings and all special effects, as graphic options made no difference.

What is causing this? Is it a pathfinding issue or an issue with too many units during star fort battles? It was so horrendous, I was thinking of just quitting the battle and autocalc'ing them. Even musket fire was annoying, with the bullets stopping mid way 3 times before reaching targets. Took 10 minutes to move units 5ft.

From what I have read star fort sieges are bugged. Was ther a breach in the wall and the ai was milling about?

Yes this is a known problem, the usual thing is to disable grass, and reduce the sound cache

so it is the bug...

lower your bulding details that helped with me

Ya, I used artillery to bash down the wall. I had another star fort siege battle, but I didn't use artillery to smash the walls, and just used tropps to climb them instead, and it didn't lag.

Also, I have maxed sound settings as well, and sound caching on. If I disable sound caching, it fixes the problem? Is it worth it though, compared to the performance loss overall on everything else?

Take a look at this thread here

I'd say this is the problem I have personally.

Using any method to make them move away from the wall (assaulting thru the breach, breaking them up with artillery, etc.) will stop the problem, try it out.

What you are describing is exactly what I get and I seem to have discovered what Chewie explains above to be true, at least for me in my siege battles. If I carry on, despite the lag and manage to get near the walls, forcing the units to move, the lag suddenly disappears.

ahh i think i just got this problem. was thinking it was 10.5 ati drivers i just installed...

same scenario have a broken star fort with some troops on the walls. as i send my men it become a lag fest even though my fps says over 100...

its from the engine

It's the ai can't make up it's mind to attack or run.

Aye, On the verge of indecision and that`s how battles are lost.
