Details: Although I am not experiencing such a problem (or any problem) in any other game I am playing on this system, i get this constant stuttering on FFXI during the title screen sequence and most importantly, playing the game. The game runs as normal for a second then freezes for a moment then normal again and so on, forever. It happens even if there is no dynamic models other than my character on the screen.
Steps:
1. i experienced constant stuttering on title screen and in-game.
2. first, i just tried using the minimum settings on in-game config options, turning off shadows, weather effects, setting character models displayed at minimum etc.
3. as suggested on various tech forums; i tried "Run as administrator", running the game in compatibility modes for windows 2000, XP and Vista , disabling QoS pocket scheduler from network settings, disabling controllers in windows device manager and FFXI config utility, disabling other USB devices and nothing worked.
4. then I unistalled the POL provided in my Vana'diel Collection 2008 disc and installed the vista/w7 compatible POL that i downloaded from official site but that didn't work either.
Date & Time: i can't really give exact date and time but i noticed the stuttering 2-3 months ago and it is still the same
