A laptop's dedicated GPU might not be used due to a few common reasons: outdated or incorrect drivers, incorrect Windows settings, the program not being optimized for the GPU, or issues with the GPU itself. You can try updating drivers, checking Windows settings, ensuring the program is set to use the dedicated GPU, and potentially checking the BIOS for GPU settings.

i tried that as well i also try other games. But the results are still the same. Also screen tears a lot. Even while using igpu (i.e normal using before this game checking) screen tears in browsers and discord. the old frames stays up and new frames are generated inside the old frames in browser and discord.😢

Hi Saugat_Gaire, thanks for reaching out! 😊

To help you properly, we need a bit more info:

What’s your exact Nitro model number? (You can find it on the bottom of the laptop or in the system info.)
Are you using Windows 10 or 11?
Have you tried a clean install of the NVIDIA driver using DDU (Display Driver Uninstaller)?
Is the laptop plugged in when gaming or testing GPU usage?

Also, if you can share a screenshot of your NVIDIA Control Panel > Manage 3D Settings > Preferred GPU, that would help confirm if the system is even recognizing the dGPU.
