I went on vacation and brought my windows 7 laptop. I start playing metal gear rising and binding of isaac rebirth, first it starts of a bit laggy but otherwise fine. Then the the madness begins. Later when playing, the lag is gone but then later sometimes it speeds up. Then it gets worse and worse. Which now its fast almost all the time. For some reason its happening on my laptop but I never got this on my windows 8. Thanks in advance.
