My HP envy notebook randomly gets spells of low fps. When I play csgo my fps are either in the 60s or not breaking 20. When i look in task manager my resources are low and not being used a ton, and i have set my laptop to performance settings. I have checked the heat and it gets to about 60c when I play csgo. Why am i not seeing more consistent framerates? Here are my laptop's specs:
8gb ram
amd radeon r6 1.8 ghz integrated graphics
Windows 10
What could be casuing this?
