ZDoom

It's been how many years and someone only just noticed this? We're still learning new things about these games.

fixed.

Actually, Heretic kills the velocity just as Doom does, it just doesn't do the 'freezing'. It gets even more interesting: In Hexen this effect is transferred to the Boots of Speed - and that is implemented!

I'm not fairly sure what momentum function is (not that tech savvy sadly) but if you mean keeping the same speed when going through then yes.

Confirmed. I tried out Heretic in my DosBOX, and as Plucky described; without the Tome of Power activated, the player pauses for a moment after teleporting (Just like Doom). With it activated, the player has no pause after teleporting.

ZDoom does it the Doom-way. Pauses after teleporting, with or without the ToP activated. I think this should be easy to fix, since we have that Teleport, but keep momentum function?

Now I just hastily created an account to get this out to the general ZDoom public. I'm not entirely sure if this is considered a bug to you guys but it seems like one to me. Here's the "bug" I'm talking about: in the original MS-DOS heretic when one has a tome of power active they can go through teleporters wothout the usual split second freeze once appearing on the other side, this isn't present in ZDoom and ZDoom derived ports.
