Get all available graphic cards & put into batch variable using Powershell

[JN-]

https://stackoverflow.com/questions/61397665/batch-file-to-get-all-available-graphics-...les-and-output

I previously managed to do this thanks to above link that uses the now depreceated WMIC.

Any ideas on how to do using powershell?

Thanks.


The nearest I could find searching was this ...

But how to put result into a batch file variable ?


https://lindevs.com/methods-to-get-available-gpu-devices-on-windows

C:\> $gpu = (Get-WmiObject Win32_VideoController).Name
C:\> $gpu
Intel(R) UHD Graphics 620

C:\> $gpu -like "Intel"
False

C:\> $gpu -like "*Intel*"
True

C:\> $gpu -like "Intel*"
True

try ..

# Get the video controller information
$gpuInfo = Get-WmiObject -Class Win32_VideoController

Thanks for trying. When I open a powershell window (as Admin) and enter

$gpu = (Get-WmiObject Win32_VideoController).Name

I just get lots or red error messages?

I managed to get this to work below, (running from a batch file) sort of. But it incorrectly returned false for all tests.
The weird thing is that when I ran it first (from within a powershell window, not batch file) I got some line, (6 lines) that returned true.
But then further testing returned all false also as in batch file.

I'm testing on a laptop that has a Nvidia GPU.


Powershell $gpu -like 'nvidia'
Powershell $gpu -like 'Nvidia'
echo.
Powershell $gpu -like '*nvidia*'
Powershell $gpu -like '*Nvidia*'

Powershell $gpu -like '*nvenc*'
echo.
Powershell $gpu -like 'nvidia*'
Powershell $gpu -like 'Nvidia*'
echo.
pause
exit

Try .. in PS

# Get the video controller information
$gpuInfo = Get-WmiObject -Class Win32_VideoController

# Filter for Nvidia GPUs and display relevant information
$NvdaGpus = $gpuInfo | Where-Object { $_.Name -like "*Nvidia*" }

if ($NvdaGpus) {
    foreach ($gpu in $NvdaGpus) {
        Write-Host "GPU Name     : $($gpu.Name)"
        Write-Host "Driver Version : $($gpu.DriverVersion)"
        Write-Host "Device ID        : $($gpu.DeviceID)"
        Write-Host "Video Memory: $($gpu.AdapterRAM / 1MB) MB"
    }
}

or .. in BAT

for /f "tokens=1" %%i in ('cmd /c "wmic path win32_VideoController get name | findstr /I NVIDIA"') do set gpu=%%i
echo %gpu%

OK. Thanks for all of that. The 2nd. code item I didn't test as (it uses WMIC which is depreceated and now gone AFAIK) the issue is that WMIC is no longer supported by Win 11 AFAIK with the latest 25H2 update.

I already have working version using WMIC which I knew was depreceated but is not much use going forward.

The 1st. item works, tested in a powershell window. Thanks.

FWIW: The code mentioned in this link ( https://lindevs.com/methods-to-get-available-gpu-devices-on-windows ) at page #1. I found also works (Get-WmiObject Win32_VideoController).Name

It's similar to what you suggested in your post #2. except with .name added.

Anyway, happy days, thanks for that.

I hope this is ok to post as although it's a Powershell query it's not connected to main topic. If not I can create a new topic.

I use this code to do a Powershell division.
REM Getting the FPS value by dividing the before / part by the after / part. An even divide like 25 fps will return 25 only without a trailing period.
SET _DIVIDENT=%_DIVIDENT_INPUT_FPS%
SET _DIVISOR=%_DIVISOR_INPUT_FPS%
for /f "delims=" %%g IN ('powershell -Command [convert]::ToDouble^(\"%_DIVIDENT%\"^)/[convert]::ToDouble^(\"%_DIVISOR%\"^)') DO SET _INPUT_FPS=%%g

Question is: Is it possible to modify the PS query to only return say 3 decimal places?

I can do so using batch by extracting only 3 chars after the period in the resulting batch variable %_INPUT_FPS%, but it would be neater to do it using PS. Thanks.

For a typical 29.970 frame rate the above returns 29.97002997003

try this .. untested

powershell -Command "[math]::Round([convert]::ToDouble(\"%_DIVIDENT%\")/[convert]::ToDouble(\"%_DIVISOR%\"), 3)"

[JN-]

Works. Thank you.

I just have to convert to a FOR command now.

Excellent.

[JN-]

Done.

for /f "delims=" %%g IN ('powershell -Command "[math]::Round^([convert]::ToDouble^(\"!_DIVIDENT!\"^)/[convert]::ToDouble^(\"!_DIVISOR!\"^), !_DEC_PLACES!^)" ') DO SET _FRAME_RATE=%%g

echo Frame rate = [%_FRAME_RATE%]

[videoAI]

what are you building exactly?

[JN-]

I have over 2 dozen small batch utils, already built. Most rely on the ffmpeg utils.

Thanks to other users here I have implemented option to get gpu's available and screen resolution both using WMIC.

Since that's now being removed by MS in latest 25H2 build I needed to replace, modify about 17 of them.

The last item above, Powershell division with decimal places option I wasn't stuck for but a nice to have ability for sure.

Thanks for help with that and Gpu availibility using PS.
