As a note just to get the game running I had to install Directx 9 which I found in a support article. Would be nice if this was included in the installation files. I never played any of The Witcher series so I wanted to dive in from the beginning and I got about 30 seconds into the game when the video quality would stutter or remain on a cut scene even though you could hear dialogue and fighting happening in the background. I finally gave up after some troubleshooting it's the shame as the beginning intro seemed very promosing. I wish GOG would at least make this playable as I paid for it!
