I have an asus laptop with an intel i3-8109u processor, a GeForce MX130 graphics card, and 4 gb of DDR4 ram. I was playing GTA V with medium graphics while MSI Afterburner was running, at the start I was having 30-40 fps and my gpu temperatures were around 50°C-60°C with only 60-70% usage while my cpu was around 70°C-80°C with 90-99% usage. After about 10 minutes, both the gpu and cpu usage started going to 90% and dropping to around 20% quickly and continuously until framerates dropped to 1-5 and became irresponsive. The temperatures of both the cpu and gpu remained the same. Shouldn't the gpu be the one running on 90-99% usage instead of the cpu? and what could be causing the sudden drops of framerates?
I would like some help and advice with what's happening to my laptop. Thanks in advance
