I've cleared the cache and the stuttering isn't totally away (but better and all the game-updates are back updated).
But I think it's more a problem that I play DKS (and other games on my Xbox) TOO long in one time so my Xbox become too warm/hot and the Xbox start to have difficulties to play "smooth" ...
So now their's only one thing I can do: play more, but with a shorter playthrough at the time ...
Unfortunality ... some of the games I have are SO addictive !!!
Especially those with the logo "Larian Studios" ...
So kind Commanders of Larian, can you imagine that it's most of the time
not simple to stop playing ? Can you imagine that ???
