I had finally decided to build my own pc, only to be met with the issue of erratic gpu usage and no it is not a cpu bottleneck because usually the cpu runs at about 70% usage the entire time when playing a game, the random gpu usage causes games to stutter quite some.
The cpu is the Athlon 880k and the gpu is a sapphire rx 460 4 GB model and the os is windows 10 and the motherboard is the ASUS A88XM-plus.
I hope this driver issue will be resolved soon. If you are asking why I think this is a driver issue and not a hardware issue is because the clocks are stable and stays at the boost frequency the entire duration of the gameplay and the pc does not crash.
My setup is basically the pc connected to my tv through hdmi (does this cause gpu usage fluctuations?)
