There are different kind of stutters and I will show different aproaches.
1. Micro stutters.
If you don't have big and sudden freezes and want the game to be more smoothly set the correct Max. frame rate (your monitor rate) in the launcher. Well if you have potato computer this will help if you decrease max frame rate additionally.
2. Global map stutters and cursor flickering.
You need to patch mb_warband.exe or change one bit manually. WSE has already implemented that fix.
Read this post.
3. Battle stutters.
-----Turn off Formations and Advanced Horse Archers AI in mod options.
-----Disable switch weapon trigger, wich forces agents to switch lances for melee weapon if enemy is near or if dehorsed.
1) Open mission_templates.txt
2) Find lead_charge
3) In the #4 trigger (counting from 0)
Code:
2.000000 0.000000 2.000000 0 145
Replace 0 to "1 31 2 1
0" keep 2 spaces before and after snipet.
You can turn this script on by changing to
"1 31 2 1
1"
Disabled trigger
Code:
2.000000 0.000000 2.000000 1 31 2 1 0 145
Enabled trigger
Code:
2.000000 0.000000 2.000000 1 31 2 1 1 145
I have tested and that trigger doesn't have a big effect. There is another trigger that should be turned off. It calculates courage effect. This trigger is inherited from Native Warband. Disabling troop routing in the mod options menu doesn't stop this trigger.
-----Disabling morale trigger
1) Open mission_templates.txt
2) Find lead_charge
3) Find trigger
Code:
3.000000 0.000000 0.000000 1 1 1 936748722493063479 0
4) Replace it with
Code:
3.000000 0.000000 0.000000 0 0
There should be one space after code block. Forum doesn't show it.
That will remove any stuttering.
