I think <dont quote me> :
That additional Intel Integrated Graphics card support was intended for Laptop machines which have both an
iGPU (Intel Integrated Graphics Processing Unit, embedded on the Central Processing Unit (CPU) such as Core I7), ASWELL as a
dGPU (dedicated Graphics Processing Unit, such as NVidia or AMD GPU cards)
Laptops with
both iGPU and a dGPU, even if the game primarily uses the dGPU for extremely fast graphics rendering, still uses the iGPU for displaying the rendered result to the laptop screen.
Such Laptops are known as Optimus setups
https://en.wikipedia.org/wiki/Nvidia_Optimus Here's my theory - Maybe, prior to Pathfinder, NMS did not support some iGPUs in combination with the games minimum spec dGPU
So people with the minimum spec dGPU or above, going by the games specifications, would expect the game to work, but would not be aware that their display iGPU (which is not mentioned as part of the game specifications), was not compatible with the game ..
.. So HelloGames expanded the range of supported iGPUs in Optimus setups that the game would work with purely to display the rendered results from the dGPU.

PC
Support for Intel HD Graphics 530, 540, 550, 580, 630, 640, 650
.
Thats my theory anyway. When HelloGames mentioned increased Support for Intel Integrated cards with various model numbers, I dont think they meant that the game could run purely from those without a dGPU, having at least a minimum specification dGPU is still needed hence why its still in the games specification notes on Steam and GOG page for the game.
I know that the game X4 in its settings at one time had trouble recognising and distinguishing different combinations of iGPU for display, and dGPU for rendering, but has since resolved such issues (see screenshot attached), and makes it known to the user that both iGPU and dGPU are recognised correctly for their setup
.. Maybe its the same for NMS, and further recognition of a wider variety of iGPUs became necessary
The fact that the games minimum spec still specifies a dGPU would seem to back this theory, and as other have said I would also think that trying to get the game to run purely on an iGPU with no dGPU in the machine would not work. Intel Integrated Graphics are getting better as time goes on, but they are no where near capable of doing the same work as a desktop dedicated graphics card chip, and its onboard Video RAM. Not even when you compare with a Laptop Mobile version of a dGPU which are weaker than the desktop equivalent mentioned in the game specifications.
