Hello guys. I've went through many forums and topics, but nothink helps or direct me to the right path.
So the problem is:
My video performance slows down significantly. In one point, everythink works fine. I play some game, fps about 120+. Then after some time fps drops to 10-. I've restarted PC. Didn't help. I've tried watch some video, the image lags so much, that the sound wasn't synchronized with video. So i did clean reinstall of system. Install all drivers from Dell sites (the original ones and even the newest from AMD), but it doesn't help either. Even flash web browser app/games lags hardly.
I think power settings are set allright. Can report if you want.

Dell Inspiron 15R 5521
Windows 10 x64
Intel Core i7-3537U 2GHz, 2501 MHz
Intel HD Graphics 4000
AMD Radeon HD 8730M
Resolution: 1920x1080px

I've tried start some game with GPU-Z on to check switchable graphics. Both, AMD & Intel, perform by their limits. Laptop heating is a little bit high, but it doesn overheating.
I even try FurMark and Unigine Heaven. Both freezes fps to 10.

Today, i will try to manually clean dust and some other day charging. But i don't think this are my problems here.

I would appreciate some help.
Thanks a lot :)

Sounds like your laptop is overheating and reducing performance to keep from burning out.
