I manage to get rid of annoying stuttering cutscene. I would like to share it, but I don't guarantee this would work to everyone.
How to Fix Temporary Opening & Cutscenes Lag
- Turn on in-game V-sync.
- Try to use borderless window or fullscreen (both work for me).
- Move the game folder to SSD.
- Make sure your pc is running on high performance mode. How to enable high performance mode: press windows button > type control panel in search box > select power options > choose high performance mode.
- Update your graphics card driver.
- Open in-game settings and adjust the rendering scale to 100% - 150% (mine is working fine on 150%).
That's all. I hope this could help those who experience the cutscene lag.
