DNF & Unreal Tech
by Steve Gibson, Dec 13, 2000 3:48pm PSTI generally shy away from posting comments made by 3DR guys on messageboards but this post by Brandon Reinhart talking about working on the DNF engine is pretty interesting stuff. (Thanks Eric). GreenMarine however talks quite a bit (Thanks Unreal-Universe) of the CPU bound limitations of the Unreal tech and how they are dealing with it at 3DR. Here's a bit:
The Unreal engine is heavily CPU bound, so our focus on optimization is more on releasing that CPU tension. For example: the Unreal engine uses span buffering for occlusion. This approach has a lot of benefits, but is CPU intensive. We have saved a lot of framerate by reducing the complexity of the span calculations and reducing the number of required calculations. This kind of optimization is unrelated to the render API layer. [...]

For an unhyped game, DNF certainly has quite a lot of interested parties. IMHO, once you reach a certain level of interest, deliberately witholding information does the same thing as hyping it. Everyone wants to know, and every little tidbit is pounced upon, torn apart, magnified a hundred fold and examined in minute detail.
I felt Diablo 2 was the bs with its SSOTW's - I mean, its a screenshot, it looks nice, do you really have to rip it apart and wring every last preview clue out of it?? Thx diabloii.net, gg. After a while I stopped reading sites with D2 information because I wanted some surprises before I actually bought the thing. Its a shame that none of the previews described how much ASS was involved in the network code, b.net servers and the wonderful caching when you attack big monsters (Duriel).
This isn't anyone's fault, i'm just saying that in the absense of hype, the community goes ahead and makes some anyway.. its unavoidable. I must confess to not being as interested in DNF as some, but even so, i'd hate to see it fall victim to miniscule examination like some other games..
3DR, release nothing, please.
Cheers,
Raziel

You should take the same tact that smart movie producers use - get out enough info to build interest but not so much that you blow the whole story.
I guess in the same sense you want to be smart and not start the ad campaign too early.

but like i mentiond i thought dx8 was mostly new features..... so the only work needed to be done would be to add effects into hardware and such things.. which would run faster but was DNF really doing a bunch of expensive effects in software? most cards wont even use a lot of dx8's new features right? i dont see how if DNF runs like at say 40 FPS now on DX7 moving over to DX8 and tweeking it would make it run that much faster?
mayb ei just read the post wrong

will this game ever be done?
I am getting the feeling Doom3 will be done before DNF.
