There's still unanswered questions about how hard it would be to build or run such a massive mission, even if it does have simpler geometry, right?
I can't wait to see how far the boundaries get pushed with TDM, since we're at the beginning of the process.
Well, running it if it is optimized properly should run as good as a small properly optimized mission (though load time would be longer).
Vis portals segment the missions into smaller pieces so you are usually rendering an area around the player, and parts of other areas that are visible through the visportals.
So in a massive mission you are still just rendering a small area around the player, not the whole mission at one.
So missions large or small can have the same performance.
Building it though, at least as much time as any other massive mission :)
Radiant is still an editor, it takes time to build missions, but I think people will be able to turn out missions faster and easier once they get the tools down though. It just takes that first step...

But I guess missions of Night in Murkbell or Mission X's size won't be possible for quite a while? Considering that I had some noticeable slowdowns in some places even in the very small mission like The Chalice, I have some doubts about possibility of really large missions in the nearest future...
Especially keeping architectural detail level of The Chalice.
That depends on the actual layout of the mission and how well it can be portalized. Drams Mission had areas where my old machine really choked on, but in other areas the scene complexity was much lower so the framerate was good again there. The size of the mission is pretty huge, so that is not really the issue, it's mostly scene complexity that matters.

@TDM Team: Guys, I have a one question about Parallax mapping: how difficult to implement it into TDM? I've heard that there are about three instructions should be added into a shader's code, but, alas, I'm not a graphics programmer...

It can be done, but with everything else that's already going on in TDM, it's quite a large performance hit for very little pay off. One of our members brought it to our attention a year or two ago.
It isn't something we'll be supporting officially. We don't want the mod to be so weighed down by graphic enhancements that it shuts out the core fan base.

is there a way to alter or remover the menu delay ?

New Horizon: Yes, I understand your care about those taffers who cannot afford themself a more-less power hardware. But, AFAIK, a parallax mapping is not so difficult thing for most modern graphics cards. Something like GeForce 8800/Radeon 3850, I think, will be able to handle such an eye-candy feature. Those graphics cards are two-three years old and cheap enough these days :).

I cant afford one.
Does that mean you will buy us some since they are so cheap ?

As I said, "

To elaborate, if you dropped parallax enhancement into Vanilla Doom 3 you probably wouldn't notice much of a difference in performance, if you put the same enhancement into TDM you would notice because we have to deal with AI, sound prop, tracking objectives, stim-response pings, lightgem calculations, ambient lighting...yadda, yadda, yadda.
In any case, maybe it's something that could be looked at in the future, but for now I don't think it will be making it into the mod in an official capacity. It might not even be something that would be compatible with our current interaction shader ambient lighting enhancements. Eye candy is a low priority matter right now.

I'm on an 8600 and can't really drop enough for a new card either. And considering some people are complaining about $10 for Doom3...

Thelvyn: I don't mean that I'd buy anybody some modern graphics hardware :). I mean that many of taffers are already have that hardware, and I think they'd welcome any eye-candy features implemented in TDM.
New Horizon: Parallax mapping is a graphics feature that runs on GPU (I mean it's a pixel shader), so it cannot slow down tasks that runs on CPU :).
Schwaa2: Don't worry :)! Your graphics card is fast enough for parallax mapping. Why do I know that? Because I ran FEAR 1 on by integrated Radeon HD 3200 in 1024*768 with almost all maximum graphics features (including parallax mapping but excluding soft shadows and FSAA), and I can assure you that Radeon HD 3200 is much more slower than your GeForce 8600.
