When did people start to expect a constant 35fps in wads?

Had some time on a high-end period-correct vanilla system and was surprised that the game rarely sustained 35fps.  My best guess would be around when Boom came out, because maps for those weren't overly complex, but zdoom ones were?

In 1994 I worked on a company Pentium 90 with 64MB and a high end Diamond video card. I didn't notice any framerate drop playing Doom II. By constrast the 486s in the office with considerably less memory and a stock video card, didn't feel half as smooth to play.

The card plays a huge role because of the way Doom works.

 

I am not an expert but I think the vanilla iwad maps ran fine on an 486DX, 8mb RAM and some reasonably fast VESA card.

According to https://www.complang.tuwien.ac.at/misc/doombench.html anything faster than a 486-66 was pretty much full 35 fps most of the time on vanilla.

I only ever got below that when a ton of monsters went aggro at once. It turns out my processor barely gave it any ram to work with. I've never heard anyone else with that problem, so it's probably not that, but it's fairly easy to fix if it is the problem.

Is go2it the most demanding iwad level?  I've found that a 486-100 is needed for 35fps in its busiest parts.
