Right now I'm playing FFXIII-2 on PC and many people say that it is horribly ported and doesn't work well on most anything. I wasn't expecting to run 60 FPS since I'm on a laptop, but 5-8 FPS is kinda stupid. Now the strange thing is that when my battery is almost dead and I plug my laptop in, my FPS suddenly shoots up to 30+. Once my laptop hits around 80% charge, the FPS drops again back to 8. So I've been playing it unplugged until I get the notification that the battery is running low, then I plug it in and enjoy smooth frame rate for an hour or two until it charges. Why does it do this? I checked all my settings, and there doesn't seem to be a difference between plugged in and on battery. Also why does it stop being awesome when I hit 80% charge? I figured that my FPS would stay great while plugged in but it doesn't. I would appreciate it if someone could explain to me what is going on and how I can improve my gaming. Thanks.
