If it uses GPU rendering, possessing physical media doesn't mean much. GPU vendors aren't that diligent about making sure old games run properly on their current hardware offerings.
Even for physical media for console games, patches DLC are delivered through the console's online service. Once that ends, as it has for the PSP and original Xbox, you're left with the game as it was originally released with whatever bugs it contains.
The compatibility situation has improved a lot, thanks to Vista. Windows Vista required D3D9-capable GPU, actually used it to render desktop, and Microsoft’s GUI stack uses the hardware too, e.g. modern WPF is still based on DX9 because compatibility reasons.
While GPU vendors indeed don’t care about gamers running 10 years old games, they can’t ignore business customers running 10 years old LoB software. As a side effect, even very slow (by modern standards) integrated Intel GPUs are usually quite good at running older DX9-based games.
