    Lenovo Legion 5 3070RTX - Very low FPS, system using vega not nvidia

    Hi

    Hoping someone can help.

    I bought a laptop last week, it is a Lenovo legion 5 (non pro) 2021 version. it has the 5800H with IGP Vega and a 3070 RTX discrete GPU. I use a Samsung odyssey G7, 240 1440p external monitor. I am using my original charger for the laptop.

    I got the laptop last week and it was great, I'm talking 130-150 fps in warzone with DLSS on at 1440p. really good performance. I installed windows 11 and everything was still fine, however the 512 nvme installed was full, I replaced the nvme with a 1tb one that I had and reinstalled windows 11, clean install and then used lenovo site to update drivers and install vantage.

    The problem
    Once I had everything reinstalled when I load a game I get 17fps in game play, AMD fidelity is an option AND DLSS in the settings. it gives the option to pick the GPU in the settings but it only has the Nvidia 3070 listed. I have tried setting the bios to discrete only. lastly i have reinstalled the entire OS using the lenovo recovery media... updated everything downloaded all the games etc again. still getting 17fps. if I change fidelity to balanced then it goes up to 40 fps. this prooves that the game is selectiung the onboard GPU over the 3070.

    The nvidia control panel is installed and shows that i am using correct native Res and 240 hz, the game picks up the monitor and shows 240 fps. I have tried disconnecting the external display and using the laptop screen (1080, 144hz) but the same problem persists.

    Any ideas of what else I can try?

    Thanks in advance.

    I thought i would update this thread with the solution in the hope that it may help other people in the future. it took me a long time to find this and I reinstalled windows TWICE!

    The solution is to carry out a bios reset. To do this simply unplug the laptop, shut windows down, when it is switched off press and hold the power button for around 45 seconds. when it boots back up it is all fixed.

    Sounds like whoever setup your laptop chose the graphics to default to the APU. I have an option in the Nvidia Control Panel to change 'Preferred graphics processor', under 'Manage 3D Settings'
    Worth noting if it happens again
