I need help. When I play games on my Late 2015 5k iMac I reach around 99% GPU usage on low graphic's settings. This never happened before, but randomly a few weeks ago it started doing this. I didn't install any updates, nothing. I was wondering if this is a known issue or something I'm only experiencing. I am running a Windows Bootcamp partition but the same happens on the MacOSX side.
My computer specs:
GPU: AMD RADEON R9 M390 (2048 mb) (GDDR5)
CPU: i7 6700k 4.00GHz
Ram: 24 GB of DDR3
OS: Windows 10 (64 Bit)
