For some reason sometimes the game does not show me the sparkles to follow. For example, in Chapter 6 the game didn't show me the two sparkles that I encircled in red in the attached screenshot.
That is not the only case actually, I remember that several times I couldn't figure out how to proceed as I couldn't see the sparkles.
I send you attached the DxDiag of my rig for your information.
Thanks in advance for your help,
Have a nice day
