Single Status Update
Yay, I managed to install new Doom on my mid-2012 MacBook Pro (on Windows 10), on an external hard disk!
And the game is perfectly playable. The frame rate is indeed slower, but nothing bad -- the game simply plays somewhat slower as well, giving me more time to react. And it's actually faster than first time I played Doom 3 with that old computer!
So glad -- knowing this, I can certainly play other cool games, such as Wolfenstein: The New Order. Probably not so much the sequel, given that it's so new and the specs reportedly so high.
I'm still a bit unsure what might happen if I'm "caught" without the external hard disk. Will Steam panic about it and try to cancel my installation?
"Probably not so much the sequel, given that it's so new and the specs reportedly so high."
If the steam reviews are anything to go by then your specs don't matter because it would crash every 5 seconds anyway.

Speaking of Doom 3, I think it's actually more memorable than the new Doom. Better? I dunno, I think the new Doom has better gameplay overall. But Doom 3 is in many ways a very unique game. Even to this day very few games can rival the amount of detail in it's level design and it's horror atmosphere is extemely well done. It also has the best depiction of hell in any video game ever. It's a shame it's mapping community did not take of more.
