1. What are your experiences with high-end computers and a high battle size? Did anyone of you reach 1000?
Nope, no matter what i put it on i seem to get this stutter, even happens at battles as low as 300. Its not lag as i still get high FPS just a weird stutter.
2. How can I improve my battlesize and get the stuttering fixed?
Lower it. Personally when i play battles in England i don't stutter, when im on a crusade i start getting that jitter.
3. Are there grafik options that are not so relevant and can be ignored? My game estimation (in the settings menu) is curently at 130%, so the game should normally work without stuttering.
Your PC can easily handle highest graphics and they aren't the problem. Your CPU might be abit low, is that card the i5-3570 or the i5-3570k? If its the K then whack liquid cooling on and Overclock that thing! Ive managed to get 5Ghz on my I5 2500k with the Corsair H80 Liquid cooling and its temps are only 40 in intensive games. So i would recommend that you look into that. Also overclock your graphics card (if you already haven't) But that card is a ****ing Beast so really it can't be hardware.
As a side note i have the same issue, in big battles i get a stutter, moreso when im on a crusade, when i fight battles in England its much smoother somehow.
My specs are:
MSI GeForce GTX 660Ti Power Edition Superclocked 2048MB GDDR5 @ Core Clock: 1019MHz
I5 2500k Qaud @ 5Ghz /w Corsair H80 Liquid Cooling
Asus P8 Z77 V - PRO
8Gb Ram
1Tb HDD
850W PSU
(although come the 26th im upgrading to a Asus 7970 3gb Card)
One thing which worked for me was turning off the battlemap. Someone here said that it is generated by Warband having to check the position and status of all soldiers on the field, so turning it off saves on processor time.
I'll go check that real quick.
