As I read I spot a lot of sub-par FPS results. Even on low.

But let me comment about the i7. Yes that's plenty for the game but has little to do with FPS results. FPS is more about the GPU than the CPU.

You have an OK laptop but not a gaming laptop. You need something like the Nvidia 1050 GPU today with the 1080p display to satisfy most gamers. Some gamers want even more than that. Also, there is no 4K laptop gamer today that I would recommend.
