The new patch did not improve this issue.
I still have micro stuttering in the cutscences.
Changes in the ini settings did not help or removed the FPS limit (tried the one in user/document and the one in the game folder)
Everything else is running with 40fps+ on ultra with hairworks on with no stuttering.

I have lips/voice desync on dialoges =(

Plot and writing are the most important thing for me in a game and this is breaking witcher 3...
I'll wait for the new patch and a new amd drive.

There is a topic with many people having this problem on the cdprojektred forums. Someone extracted a pre-rendered cutscene and played it outside of the game. It is smooth outside of the game. This is a problem with the in-game movie player. I cannot post the links to the videos in this forum. Search for them on the cdprojektred forums if you want to see the big difference between in-game pre-rendered cutscenes and outside of the game pre-rendered cutscenes.
