Thanks Emeg, no problem with the language.
Me english is bad, that`s why I wrote in german… ^^
First; yes, the Gforce-Driver are actual.
And as far as I know I haven`t not too many other programms in the back.
I also tryed to play directly after a restart of the PC, with same bad result.
And there is no Bandicam or something else, cause I first need to be able to play the game, before I can start recording it. ^^
But thanks, I will try it next time with stopping EVERYTHING in the back, so I will see.
