Hi:

Some players continue to complain stuttering issues in some localized versions such as Chinese version.

We do not have direct proof but there're some indirect clues:

Many people describe this issue as "everything seems to be fine at start, but AFTER several hours of playing, stuttering becomes more frequent".

And they usually say they need to restart the game or even the PC to regain the visual fluency. Makes me wonder what's happening behind, and why this issue seems to be specific for these localized versions but not English version.

Hope this information helps.
