I remember trying to run a game, Rise of the Triad, which was built with an improved Wolfenstein engine iirc, and having it struggle on my 386 unless I made the viewport as small as possible. At which point it told me to buy a 486... well I did eventually, I guess it worked.

Had the same experience with Doom II. Got it to run surprisingly well on a brand new Tandy 486DX2 + 4MB RAM, though I seem to recall having issues with SoundBlaster compatibility.
