ZDoom

Wait, so with that we could finally fix the frozen time , remove the gross hack bridge and add a proper 3D floor for +100fps?

And also, people are already doing workarounds for doing the same thing (couf brutal doom came in mind) so why not add THE oficial way of checking what mods/iwads the player is playing (I never played with that feature but for map specific changes I'd get the map name + the player Spawn pos and angle, I don't think there would be maps with the same map name + the same player Spawn coord)

You couldn't really use this to affect Frozen Time because this is a ZScript request and ZScript can't modify map data enough to remove parts of the map (you'd have to remove the copious amounts of double sided lines, which is what trips the renderer up) since that would require nodes to be rebuilt while the game is running.

... not to mention replacing them with 3D floors. Doing that will indeed improve performance quite a bit - but of course this cannot be from inside the engine.

I'll be using that until it's mainlined, thank you.

Mark this a 'yes' now.

Wow... thanks.
