Why my CPU speed just running at 0.50 GHz while gaming about 20 minutesI have Acer Swift 3 SF314-56G

I have Acer Swift 3 SF314-56G. With i5-8256U, Nvidia MX250, 8GB RAM (2x4GB Dual Channel).

The problem is, when I play a game up to 20 minutes, the performance got insanely decreased.

I detect the CPU speed running at 0.50 GHz, also it causing my GPU usage decrease.

as you can see here, 1st pict is when I just launch the game

and then the 2nd one, when I run the game around 20 minutes

You can clearly see the differences between those picts. From the FPS, CPU speed, CPU Power, GPU Usage.

Eventhough when I change the graphic settings to the lowest value at 1366x768 resolution, it won't fix.

Also I've already update all the drivers that I need, such as GPU Driver, CPU Driver etc.

Did you guys know where the problem is?

And how to fix it?

*sorry for my terrible english

Are you seeing this while running on battery or with the charger connected?
