[maximka52]

My friend has problem, when he playing games after 15-20 min FPS in games drops from 60 to 15. No overheat, no viruses. What can be problem?
Sorry for my bad English.

What are you using for temperature monitoring?

Aida64

Found that there is no temperature sensor for Nvidia GPU

Try using HWMonitor instead, it should read the sensor.
What are the hardware specs on the laptop?

Installed olders Nvidia driver, now its working fine, no FPS drops.

Try using HWMonitor instead, it should read the sensor.

Also wont read sensor. Tried also MSI Afterburner, it shows temperature same as integrated Intel GPU.
