When I got a floppy with Doom, I played it on a clone 386 and it ran well (and in fact better than on the PC's of other people I knew).

Not so much because the standard for gaming in 1993 was relative to gaming in 1993 but because Doom is a great game even at 15FPS because it was designed to be a great game even at 15FPS.

The last minute of the video shows Doom running in Windows Task Manager.

I highly recommend just seeing those few seconds (start at 14:13)

Interesting timing…I just finished John Romero’s book Doom Guy. It’s definitely worth the read if you grew up on id’s early games.

Masters of Doom is also an excellent read.
