Thank you for your time writing this. fallout 4 is my most favourite game i get low fps there too like 45 fps max. but idk votv have like half-life 1 graphics the game not suppose to get low fps. shadows dont lower my fps only the lights at base. when the transformers turn off the fps skyrockets to 75 or when im out of the base gathering sattalite data. tried the vulkan mode get few more fps but the game needs to be optimized
