I had this issue since the beginning of EA, the game keeps loading new textures. It is very noticeable during cutscenes and when arriving new maps. The new patch kinda made it much worse. I assume it has something to do with the fact the game is not on an SSD drive but I honestly have no idea. I'm running the game on a laptop so that might be it, but I don't think it should matter since I can run Witcher 3 pretty smoothly on the same rig, and that is a demanding game. The graphics of this game are good, but not that good to justify these slow downs and texture issues
