Doom 3 source code packaged and tested.

Riva TNT2?! That thing was 6 hardware generations old by the time Doom 3 came out. Who cares how well it runs on such old trash?

it was supposed to be some kind of joke
you cant run Crysis on TNT2
TDM is laggy because d3 engine is shit engine,not because of my retarded hardware (4gb Ram 512 Vram GeForce GTS250 ect)

GTS250 is just a rebadged 8800GT. Doom 3 would run really well on my 8800GT and 9800GT when I had those cards. You sure that something isn't wrong on your end?

Yeah it even runs great on my cheap GT440. I don't use insane resolutions or AA though... just 1280x1024. I still live in the "90s, as dethtoll will agree with.

On the flipside, I do somewhat agree with you SH. It sucks that we can't have all windows be translucent in 2011. I really wish we were at a point where I can be on the top floor of a mansion looking out through a window at guards passing below the way I could in Heist Society. I'm not even a mapper, but having to isolate parts of a level sucks and is limiting on immersion. Maybe this can be fixed with the source code, I don't know.

doom 3 is well optimized corridor
TDM lags when you got something like this :

What OS do you use SH?

by the way,Crysis 2 runs pretty smooth,so there is nothing wrong with my end

IIRC even the author of that mission originally said it wasn't fully optimized. The revised version ran and looked much better than the original one. It even was playable on my junky P4 machine.

17 - 20 FPS in original version or 25 in v2, it doesn't matter
d3 engine is poorly optimized by itself.Look at Far Cry,it was playable on my oldest P3,it handle a lot of polygons,there is dynamic light and pixel shaders.But it requires 3D - modeling skill to make custom geometry

I don't place John Carmack on quite the pedestal that some do, but I'll happily credit him with knowing how to program an efficient game engine. Hell, he's been doing this (writing 3D engines for first-person games) for longer than almost anyone.

For the specific features that it offers, I would bet that the Doom 3 engine is rather well optimised.

Serious question: Has anyone seen a good looking outdoor environment with sunlight in the Doom 3 engine? Maybe you have screenshots or a video example? Every attempt I've seen at doing daylight stuff resulted in washed-out looking lighting. Granted sunlight isn't what TDM is designed for anyway.

I subscribe to the theory that any engine can produce good visuals in the hands of a good author. Some maps for e.g. id tech 3 still look very nice like this. (http://www.youtube.com/watch?v=3zp889rI0EQ)

Notice the large amount of geometric detail: walls with 3D panels, rounded railings, windows where you can actually see outside into the mountains. Hell, even the fluorescent light bulbs are 3D.

This is the best looking daytime demonstration I can find for Doom 3.

That's the engines biggest benefit, and it's biggest problem. The version of Doom 3 TDM is using is optimized for, well, Doom 3 like environments. High detail in tight spaces with a controlled view distance. For large outdoor environments, the TDM guys have to control just how much detail is being rendered by the engine, since it'll attempt to draw everything that's viewable at full detail. Near or far, it doesn't matter. It's being drawn just like you've got your face right up against it. Since I don't believe there's much in the way of tesselation or instancing in the current D3 rev, this would suck for something like, say, a field of grass and trees. It can even cause potential problems with large open hallways filled with details, like statues and banners.

How they could fix that, I have no idea. But they're a clever bunch over there. I'm sure they'll find a way.

When they do, and streamline some of the mod's more hacky implementations into the engine, you'll see a HUGE performance boost.

Doom 3 ran at consistent 55-60 FPS at Ultra 1280x1024 with 16xAF and 4xAA on my old 7900 GTX system and it was pretty much the same for TDM the brief time I tried it on my old system before the upgrade.. I have seen your other posts and you really, really dislike iD Software, so your conclusion doesn't exactly come as a surprise.
