Hello! I have an Alienware 15 R2 gaming laptop, and I've been having a new problem recently. Whenever my laptop's on battery, it drops to 30 fps (normal, not an issue) and when it's charging, the FPS return to normal, at 80-120 fps. However when it finishes charging, my fps drops to a stable 49 fps. I've fiddled with both the Windows power options and Alienware Command Center power options, still happens. What's possibly the source of this? Thank you!
