Hey there,
Try your best to keep to one thread. Multiple threads and answers can confuse you and us
Your CPU temps are pretty high on your vid. Your CPU is throttling. Although, it's not throttling that much. Have you the CPU set at a max of 3.6ghz or something? I would expect it to boost to about 4ghz all core under load. At 90-93c on your CPU, it's defo throttling. This can have an impact on your gaming.
What gaming settings are you playing in the vid? What resolution. What's the model of the laptop?
You might look at some options for cooling the lappie better. Do you have a laptop cooling pad? If not, get a decent one, and seat your laptop high at the rear on the cooling pad. This will allow more airflow/cold air to get into your cooling system, and give lower temps, with higher performance.
Consider undervolting your CPU with Throttlestop. This will reduce the voltage going to your CPU, thereby reducing heat output, and allow your CPU to boost higher speeds, and for longer. It will also reduce fan speed and noise.
You can also consider re-applying thermal paste on your CPU. This can have a dramatic effect on your CPU/GPU temps and increase performance.
