Hi game-developers I would like to know whether there is a way of retrieving data about your videocard programmaticly. I would be interested in the following information: Vendor, Name, Version, Ammount of memory and maybe things like GPU speeds, mem speeds or something like that. I know it's possible to retrieve this info, because programs like Everest can do this. So, can anyone tell me how to do this? Thanx a bunch! ;)

Vendor, name and driver version is possible with D3D (IDirect3D9::GetAdapterIdentifier). I believe you can get the same info from OpenGL. Anything more than that and you'll probably have to do some horrible driver specific hacks.

I think, amount of memory and GPU speed and thinks like that is not receivable via the direct3d enumeration structures and functions.
I have never tried it, but you could also think about performance tools form nvidia and amd?!

Check out the directX caps viewer to see what is receivable with the enum functionality.

I believe DirectShow can get total video memory, and D3D can report available texture memory.

When I write a log file I always output general PC info like CPU, OS, RAM, video card, audio card etc. All this info is available by using WMI. It's even easier to access this info in .NET Framework using System.Management.

Thanx for the quick replies. ;)

Does anyone know how to do this with OpenGL?
And what exactly is WMI?

Thanks again. :D

WMI is Windows Management Instrumentation which can be used to query hardware info.

Here is an example using C# to get information about the video card.

ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_VideoController");

foreach (ManagementObject obj in query.Get())
{
WriteEntry("Video Card: " + obj["Name"].ToString());
WriteEntry("Video Driver: " + obj["DriverVersion"].ToString());
if (obj["AdapterRAM"] != null)
{
double videoRAM = double.Parse(obj["AdapterRAM"].ToString()) / 1024 / 1024;
WriteEntry("Video RAM: " + videoRAM + " MB");
}
}

This prints at least some information about the display adapter via OpenGL (from wglinfo.c):

printf("OpenGL vendor string: %s\n", glGetString(GL_VENDOR));
printf("OpenGL renderer string: %s\n", glGetString(GL_RENDERER));
printf("OpenGL version string: %s\n", glGetString(GL_VERSION));

On my laptop it prints:

OpenGL vendor string: S3 Graphics
OpenGL renderer string: VIA/S3G UniChrome IGP/MMX/SSE
OpenGL version string: 1.2

@Headkaze: Thanx for your info. However, i don't use "managed code", so i need some other snippet... nevertheless thanx. ;)

@SnotBob: Thank you, very usefull!
