I don't know if this has been reported yet but in some cutscenes. The screen tears. For a split second. A 1/4 of the screen (bottom and right side of the screen) turns black. Then returns to normal. Also I notice abnormal frame rate drops in areas like forests and Oxenfort. I am running a GTX 2060 Super and an overclocked Ryzen 7 2700x. It should easily run it off Ultra with 60 frames minimum. I know this cause I had the Witcher 3 Rework HD mod installed and many other graphical update mods prior to 4.0 and the game ran like butter. I'm not broken up over this though as they are not game breaking bugs but over time and if they remain consistent, they will ruin the overall feel of the 4.0 update. I first began to notice these screen tearing instances while playing Heart of Stone DLC. As I was playing the game again and the update 4.0 came out right as I was starting the DLC. The game looks amazing. With new mods. It will flourish and bloom for years to come. However I believe a hot fix may be needed for some of these bugs. If I can get a picture of the screen tearing. I will post a reply here with the image showing the graphical issue. Thanks for the amazing update CDPR. Just fix the bugs and cook it a bit more for the PC side and it'll be perfect.
