Why don't I have a custom title by now?!

Doom runs at a constant frame rate of 35 FPS. Well, it can run more slowly if your hardware isn't powerful enough; but it cannot run faster. You might have a Beowulf cluster of a thousand Cray supercomputers, Doom will still run at 35 Hz.
Most computer screens nowadays are LCD with a refresh rate of 60 Hz. (Some can get higher refresh rates, of course.) 60 Hz is better than 35 Hz, smoother and stuff.
With some source ports, framerate is uncapped. That means that Doom might run at 3500 FPS, no problem. The simulation is still only updated 35 times per second, because the entire game logic is inextricably tied to constant-length "ticks"; but the renderer can still update more often and interpolate the views to make it look smoother.
(The 35 Hz in Doom is tied to old CRTs which used to have a refresh rate of 70 Hz. Wolfenstein, which is simpler and less resource-intensive than Doom, runs at 70 FPS. Some of the console ports of Doom run at a slower tic rate, such as 30 FPS for Doom 64 or 15 FPS for Jaguar Doom IIRC.)
