You have correctly displayed the value of the main video card.

Did not detect Intel (R) HD Graphics 4000


Did something go wrong with my adaptation?
Or maybe the DXGI I used doesn't work for that.

WMI class ( AdapterRAM ) does not support video cards over 4 GB.
Only for that reason the matter continues.

try this one, you can remove the DXGI code if you having issues and just use the registry. Should produce the same results.

Thanks @Razor12911

I just didn't understand one thing ...
In your code above, the registration information overlaps the GDXI values (if parametter UseDXGI = true).
Shouldn't there be an "end else" in place of "end;"?

        inc(i);
      end;
    end;
  end else
    for j := 0 to SL.Count - 1 do
    begin

If someone using older versions of Delphi, I attached the example of Razor12911 adapted for Delphi 2010.
Thanks again Razor12911 for the code, it's working perfectly, especially the version using registry that also detects the ON-BOARD video card.

[Razor12911]

I made it to work like that for a reason. Remember you said your intel you was not detected. So after dxgi is done detecting gpus using its methods, if any gpus were missed then registry code adds the remaining gpus. This is why I didn’t use “else”.
But then you might say why not just get rid of dxgi if doesn’t detect all gpus.

Here is why, registry skips gpus with names that have already been detected which means if SLi/Crossfire was used, registry method will not be able to detect this but dxgi will be able to.
While dxgi has issues of detecting intel gpu, registry helps dxgi
Plus we have no idea if the same registry idea works on older operating systems so it’s best to have both methods working together

So you can see why both code have to exist because they nullify the disadvantages they both have, furthermore. Dxgi has issues detecting gpu size in x86 because the value type used in x86 has the same issue as with wmi adapterram where gpu over 4gb is misread.

Tl;dr both code help mitigate their own disadvantages so the code works flawlessly

[Cesar82]

@Razor12911
Now I understand. Thanks!
There will only be differences in the results checking or not DXGI if you use SLI/Crossfire.

It seems to be working perfectly.

For those who have Inno Setup 6 installed and do not have the knowledge to change the script and want to do the test, I attached to this post the script adapted for Inno Setup 6.0 or newer.

retrieving directX version makes the setup to take more time then if directX is not added in script. pl look into it.
