NPC speech problem, not sure if its sound related

I'll list my computer spec, just in case there are any arguments...

 

CPU: AMD 550 BE (2.9GHz)

RAM: 4GB ddr3-1033

video: NVIDIA 550Ti 1G ddr5 (not overclocked)

OS: Win7-32bit ultimate

 

I believe those should be enough to tell you guys that i have good enough hard ware spec to run the game..... but every time i play, pretty much the graphics intensive area, i get lag when NPC are talking, i'll give you an example...

 

if a village were to say

" I have a pretty busy day ahead, please don't bother me "

in actuality on my computer, it would sound like this... not really distorted, but rather extended

" Iiii hhhaaavvveee aaa pprrrrrttyyyy bbbbbuuuu......" < i'm sure u get the picture

 

at first, i thought perhaps the scene is a bit too graphically intensive, so i try to rotate the camera a bit, to lower the background rendering... but that didn't help

 

so i'm thinking 2 things, whether my CPU isn't powerful enough, or there is a bottleneck on the system

 

anyone else has similar problem?

 

thanks

Some have reported that putting the ds3 process on Low Priority (through Task Manager) solves the issue.

i'll definitely try that when i get home

 

are there other things i can do to solve the problem? i'll put all of them to work
