Physics in Doom3

Recommended Posts

Okay, I don't know if anyone has the alpha and I don't think this is a bannable offense for asking (god I hope not) but can you tell me if the Doom3 engine has Ragdoll physics a la UT2K3/Raven Shield? The models in the game look great, but am I going to have people hanging over cliffs by their ankles, and so on, or do the models conform to the environment? It would be an awful shame for such an exciting game to have the same non-existant physics that you saw in other good games like Quake3, MOH, etc...

While I'm at it, my new system... Would it run it?

AMD Athlon XP 2200 1.67 ghz
VisionTek Nvidia GeForce3 Ti200 64 mb
256 Megs PC2100 SDRam
100 Gigs HD Space spanning two hard drives

I don't want to buy anything else... lol

1 - No, you won't be banned for talking about the "demo", only for posting links to it or constantly asking for it.
2 - This really should be in the Doom 3 General forum. I'd move it myself, but I'm not a super moderator.
3 - Read this FAQ about that.

The minimum system is something like 800mhz with a GeForce 2, although obviously you'll have to turn every single graphical option to the minimum to run it on a system like that.

GeForce256, or Radeon 7000, ain't it?

And you probably wouldn't have to turn them all to minimum. Turning off real-time shadows would probably be the, well, you know the rest.

I suggest waiting until the thing comes out, read a few reviews, and decide if it's right for you.

Why? His primary question is asking about ragdoll technology in Doom3...

Which as BNA has said, is included in Doom3.

Yes, DOOM III includes so called "advanced" physics engine, but AFAIK it's not Ragdoll, but something that id did by themselves.

It was shown on leaked video, have been discussed several times and I've even tested it with leaked alpha.

The physics of DOOM III was even discussed in these forums I guess, did you try to search?

Eh? Ragdoll is actually a specific engine or something? I was just using that word as a general description for the type of physics, ie, bodies fall and distort like ragdolls.

CPU-wise, second only to the physics engine. Vidcard wise, scaling down the resolution is the biggest advantage ever, just like in the software rendering days.

What about AA? Scaling down resolution won't help as much as disabling AA IMO.

1.67 GHz Athlon XP is 2000+, not 2200+. Or have you down-clocked you'r AXP 2200+? AMD Athlon XP 2200+ should be 1.8 GHz.

They'll both make a difference, but I would much rather lower resolution than disable AA.

Most newer graphics systems support "Performance" AA, which is really superior to "Quality" AA. So "Performance" 6xAA uses about the same power as "Quality" (normal) 2xAA, but looks WAY better.

Yup, but talking of Laguna's GeForce 3 Titanium 200?

Well I played half of the damn thing on a P3650 256 ram and a geforce 2 mx400 and it ran like shit but it still ran.

Well, it ran almost normally (20-30 fps) on my system

If you can actually play the game, then in no way can it be considered unplayable. If it's not worth playing with all graphics settings at low, then it's not a very good game.

On a Dell discussion site, two computer nerds were telling others that Doom 3 would not run on a Radeon 9000. They said that it would require AT LEAST a GeForce FX 5600 for bare minimum, and that it has a ton of features that require a DirectX 9 card. Freaks.

Enabling AA/Anisothropic Filtering is more of a global, personal preference rather than a game option. That's why I'm ignoring it.

All ready owning a

Keyboard,

Printer,
Speakers,
and so on and so forth I did not feel, at the time, that it was important to list all of it , and I didn't. I will try to make it more clear next time. heh

A mainboard and a power supply is not any thing I will do any big research on because that is not as important to me. I only want to see if I can use it or not for my other components.

I think, that it is almost pointless to buy Radeon 9700 PRO while looking at Radeon 9800 PRO's prices ;)

Anything support T&L, but Im not sure if the 7000 (RV100 core) does support T&L; ATI may have ripped it out (Cant remember :/)

I dont think Doom will be as demanding as everything thinks it will be either. There are tradeoff's being made, instead of ultra-high polgygon counts we have ultra-realistic lighting, and so on. Even HL2's renderer seems like it will be more demanding.

You are definitely right about this... I've seen more detailed Q3 maps out there. They manage to make it look really detailed though, so I guess the lower level geom. polycount doesn't mean shit.

I think I would invest in some RAM... Say, some higher-end PC3200 DDR.

Whoever those Dell guys were, they're being silly fools. Carmack hates coding for DirectX. He said as much in the Quake days. He's been doing everything with GL, except when he needed some ASM code in there or something.

From what he himself has said in interviews, DooM III should be able to run (in theory) on a GF1, just really badly.

However, playing this game without the shadows will probably ruin it since the gameplay is designed around the really really scary atmosphere. There's a neat little mod started up for Tenebrae that shows that. You can see the shadows coming around the corner and it's damn scary.

The physics engine in DooM III is good too. Can't wait to compare specifics in it with HL2.

For anyone interested, here's some new info on Doom III becnchmarks.

Hm, I think we're fooling ourselves at this point by saying Doom will be playable with old cards. Sure you might be able to technically play it, but will you be playing it how it was meant to be played?

My point exactly. If you can't play a game with the settings maxed, you're not really playing the game. You're playing an approximation of the game. It's pointless to play any non-competitive game if you have to reduce it to a gooey mush to play it at any sort of decent framerate.

At any rate, we've been over this a thousand thousand times, and this point has been established over and over, so I don't know why I bother. If people aren't getting it now, they're not going to.
