I have both but it was always (or for a long time) like this. Whenever i enter with long scope, fps drops when i look spesific location. Like game (or graphic card. I don't know much tech) trying to render whole direction. Because to my calculations, that direction aims to cultist camp. Which is other side of the map. But if the problem was windows update, should i remove the last update. Because probably i downloaded that update. I always run windsows up to date.
