If this is a problem with graphics and switching it, I don't think I can do it despite trying. I even switched the computer to energy saving mode ... I'm just not a specialist in this field. All the time I wonder why the movies (animations) from the file play smoothly and without problems in the game there is no vision, there is a black screen and you can hear the sound ... after all, the game does not draw pictures itself but plays the required file ... it is as if it were a problem with the player built into the game and my codecs ... something can't see something ... Or maybe there is an option in the game to turn off the vision in animations? in one of the games I played it was possible ... Ps. Radeon 6600M / 6700m is one graphics card with this name.
