A lot of people including me are having an issue with the game Star Wars Battlefront 2 (2017). Everything runs perfectly fine, except on the map called Kamino. There are really big frame drops when lightning occurs during the game, it's so bad that it literally made the game unplayable on that map. It doesn't happen with Nvidia GPU's or GPU's from the RX 5000 line. So it's probably a driver related issue.
