I read in an article in a rather technical computer magazine that stuttering can be there because some components in PCs are
too fast. Too fast for oher components, which are always running after them, thus creating the stuttering.
If this is true, now everyone would say "this can't be !" - and especially owners of high-end machines would not believe that their "machine power" would be too much for the processing of a game' data. Because our logic says u : Normally, it would be different.
I have seen a similar case where "maxing everything out" actually ruined a game completely, but due to totally different reasons :
For Drakensang 2, in the official forums a self-called "haxx0r" found the game and the fights totally boring, the game boring, and everything ending far too fast - to him, there simply was no chllence at all.
Why ? Because he maxed everything combat-related out. He put everything into combat. He completely ngnored the social interacion part in a game that puts quite a bit of emphasis on social interaction.
Thus, he killed his own game by unconsciously making his on character far too strong - the exact opposite of what's now the current fashion in gaming. Everyone has to be god-like at least (

to Larian

) , but everyone findfs low-power characters ultimtively boring thus no-one wants to play thm - although they give a much, much better challenge. Has anyone here played the game called "Evil Islands" ? Now THAT is an absolutely low-nd powered character with a LOT of challenge !
Same might go for too strong machines : Some rather weaker components can become bottlenecks within the system,. where oher, too fast components, can do nothing but wait, until the slower components - which define the speed of priocessing, then - are ready with processing their data.
Maxing everything out might not always be the right thing. Balance is better, imho.
