I have an Early 2015 Macbook Pro. I removed OS X and installed Windows 10. I installed Bootcamp drivers and everything works great except for one thing.
Sometimes, not always, when playing or watching HD Youtube videos at fullscreen my computer gets really slow, so I looked at the CPU frequency and it's limited at 500MHz or 900MHz even when the CPU Usage is 100% on each core and the temperature is about 70 Degrees Celsius. This doesn't always happens, maybe I'm playing great with the CPU at 2.7GHz for hours, but sometimes event after playing 10 minutes the CPU suddenly goes down to 900MHz at best. I tried:
- Installing ParkControl to force CPU Frequency to maximum but it doesn't work
- Using High Performance power profile with minimum CPU State to 100%, doesn't work
- Trying to force the CPU to get higher frequency using some CPU stress test, doesn't work
I just simply don't know what's happening, the temperature is not high so I don't think it's thermal throttling. When playing games (DotA 2 in my case) and the CPU is being limited as soon as I exit the game the core frequency goes up.
