This game has awful optimization issues. For one thing, the menus are locked at 30fps. Then it jumps from 30fps to 60fps during gameplay, While trying to play in 4k resolution with an RTX4080, I was experiencing terrible stuttering and frame rate drops while moving the camera around in certain areas such as the main section of the castle in the second level. I was able to fix this issue by lowering the shadows and lighting setting to LOW. I found that even setting this to MEDIUM caused the issue to return. In case anyone is experiencing the same issue, try setting the shadows and lightning to LOW. It makes a big difference.
