Battlefield 2042 not using the right GPU

Lenovo Ideapad Gaming 3, GPU Nvidia 3050(laptop 85W), APU AMD 5600H (has integrated graphics)

Had a similar problem with fallout 76, but after finding a reddit post with the following fix:

''Go to your documents, find the folder "My Games/Fallout76". Open the Fallout76Prefs.ini and find the line:

sD3DDevice=

Now, this is the GPU the game actually selects.'' (typed in my GPU and it Then used it) No other fix fixed it, the same ''fixes'' I have already tried on battlefield 2042 and which haven't fixed the problem)

Before that the windows 11 Taskmanager showed the nvidia gpu not working nor did the nvidia performance overlay display any activity in that area and by any I mean 0gpu usage. The FPS was maybe 40 while looking at the ground or more. After the reddit fix I was running the game high with no issues. So all the things I read about it being the hardware issue went out the window. So now the twist, I bought Battlefield 2042 before Fallout 76 and refunded Battlefield 2042 before finding that fix and now I return. I couldn't find a way to fix it and as I continue to search, I turn for ideas here.

Reading threads even here and seeing the same problem with the same laptop I think gives me great comfort that nothing will come of this, also someone with a dual GPU setup in a desktop pc. So can someone just straight up tell me that there is no fix or can I wait 6 months and maybe hope? Or even better I want this puzzle to be unending so send me on a wild goose chase. Or I missed another reddit post with 12 upvotes that fixes the game that could in theory have a way of selecting the right GPU or give me the chance to change something in notepad and have it run from the Nvidia GPU.

To robot the problem:

Issue with Battlefield 2042 not using correct GPU

Laptop has 2 GPUs One is 5600H integrated GPU Other is 3050 laptop 85W

Tried Nvidia Control Panel settings, did not work.

Not going to disable the IGPU in the Bios

Game 100%  running off of IGPU

Previous games like Battlefield V, Cyberpunk 2077 running good on this system.

Same issue had with fallout 76, fixed with editing 

"My Games/Fallout76". Open the Fallout76Prefs.ini and find the line:

sD3DDevice= (Here I added 3050 Laptop GPU as it is named in my system and it fixed the problem of Fallout 76 extremely low FPS and the Nvidia GPU being at 0% usage in Taskmanager and Nvidia Performance Overlay)

Need help with problem, thanks.

 

Edit:

Forgot to add that the fallout76 issue presented with the same kind of problems, unable to change the screen resolution and by that I mean there is no selecting or applying that change. I can go left or right on the in game menu or enable it from PROFSAVE_Profile but nothing changes, there are just arrows with nothing under where I should be able to at least see what I can or can't select. Game boots in a small window. Sameish was the problem with fallout76, changing the equivalent of PROFSAVE_Profile document/file fullscreen mode made the game crash on launch and the mentioned fix was the only and right way. So if there is a way to find something like what was found, adding a manual line to some file that makes the game used the right GPU I would be very very happy to hear about that.

    @Opakaz1 In nvidia controlpanel ya could select nvidia for bf2042
    Or ya could disable igpu in device manager so nvidia gpu is only GPU
    But ya could also disable igpu in BIOS , so all programs (windows) will only use the nvidia gpu !!!!

    Cheers

    Have done the first and won't be doing the other 2, because I'm pretty sure it will brick my system or it just won't work. The laptop doesn't have a mux switch, the display is still handled by both GPUs the heavy load on 3050 and the information is put through the IGPU into the display. Nvidia GPU can not connect straight into the monitor nor is there a way to have an external display only connected to the Nvidia GPU. If I disable the IGPU I am sure the display will just not work.

    @Opakaz1  try turning off Hybrid mode in Lenovo Vantage or the BIOS of the machine.
    This should allow the laptop to always use the Nvidia card.

    Update us please !

    PS check also if there is a bios update !!!!

    The system does not have hybrid mode, but updating the BIOS Did help for One match. The game ran fine for the duration, on mid settings 60 fps. The same problem is now back, I updated everything else and tried nvidia control panel settings again, but the game isn't using the 3050 again. Other games are running fine.

    hey there. So it seems that alognside other games such as age of empires 4, the game does acheck comparing available VRAM on all devices and chooses one that way, TERRIBLE design choice. The solution? go into your bios and decrease allocated ram for integrated graphics from 4gb to 2gb

    hope this helps!

    I have the exact same issue and the exact same laptop.

    Cannot turn off the Integrated Graphics GPU in device manager because it disables using any monitors (I think the HDMI port is connected to the IGPU).
    Also I cannot find a place in Lenovo's BIOS that lets me decrease the allocated VRAM for the IGPU.
    If anyone finds how to change the allocated VRAM or if you find another fix, please let me know in this thread.

    @Jarekgaming19 Hmmm it should be possible to set memory for internal gpu.
    Maybe a bios update is needed , or google for vram with youre laptop brand and type. Im sure ya find an answer !!

    I recently installed the latest BIOS update and still nothing. Apparently there is some "developer mode" for the BIOS that can be accessed by pressing a key combination, which goes like this: 

    1. Power off completely.
    2. Press the power button.
    3. Repeatedly press F2 to enter BIOS.
    4. Press the following key sequence 3 times, one key at a time: Fn , R , N.
    5. Press F10 and Enter to save and exit.
    6. Repeatedly press F2 to enter BIOS, that reveals the advanced settings.

    Source, the all-reliable Reddit thread with 12 upvotes: Accessing Lenovo Ideapad gaming 3 15ACH6 Advanced BIOS options : r/GamingLaptops (reddit.com)

    Anyways, this doesn't help at all since it brings up a lot of useless options but no option to modify VRAM.
    Another link from the Lenovo Forums further backs this up: B590-No-option-BIOS-to-modify-integrated-graphics-vram - English Community - LENOVO COMMUNITY
    I've seen videos of people modifying VRAM on older Lenovo laptops, but the new BIOS doesn't allow it.
