Any area that has a lot of moving platforms (eg. E2M3) destroys the FPS when it is in the player line-of-sight, as the CPU needs to calculate all of the platforms - this was on my 386SX-40. Any situation for where there's a lot of active monster AI (eg. HR2FINAL.WAD MAP32) will also destroy the FPS, but that's an unavoidable situation - I can still see sub-30 FPS on a 500Mhz Coppermine Pentium III with that specific map, but I use that map with a tool-assisted UV-max demo purely for benchmarking.
those are interesting cases that deserve some profiling - it might very well be a case of suboptimal algorithm doing something stupid.
