Unreal Tournament 2003, Now With More Ogg

Alizarin Erythrosin writes "Unreality is running an article today about a hands on preview of Unreal Tournament 2003. An interesting bit was on page 2, saying that Ogg Vorbis is being used to compress the audio for the game." A nice screenshot demonstrates some of the eye-candy.

lame graphics?

[Anonymous Coward]

Am I the only one who thinks these graphics are well kinda lame. Maybe it's a semester of taking computer graphics, and recently being exposed to real time radiosity engines that is spoiling me. :)

I have a silly question

[interstellar_donkey]

Why would you want to have any sort of audio compression taking up CPU cycles in a game that is so processesor depedent?

These sort of games seem to work by pushing computers to their limits, so it just seems odd that they would include something that takes power away from graphics/engine, espically when it's really not needed. (standard CD audio can be read off a disk with next to no CPU usage)

Am I way off base here? If so, let me know why.

My first thought: Better to use the CPU than rely on disk I/O.

Let's face it: if you don't compress the audio file, you're going to be relying on disk I/O to get the file out. That's going to suck in a fast-paced game. If you can minimize the disk I/O, you stand a good chance of speeding up the game.

1. Any recent FPS is not CPU-limited. It is video card-limited. (Except for really low resolution, color depth, and detail, but nobody plays that any more).

2. On modern CPUs, MP3s take about 1% - 3% load to play. I expect ogg to be similar.

In short, CPU usage is a non-issue.

For one reason - on 3D games the video card is usually the bottleneck.

Right, but at 10MB/min for CD audio it takes up A LOT of space that could be used for textures, models, levels, etc. A half hour of music would waste half the space on a CD.

You made an assumption based on Unreal Tournament actually. It is a fairly well known fact that UT was very CPU dependant(Q3 being vid card dependant).

Well UT2003 is a totally different. The latest version of UT is v436. UT2003 should have a version number in the 600's... then old engine was meant to run great on 3dfx cards... the new one will not(a V3 will not be able to run the new version).

Now back to the cpu myth. They changed the engine to allow for the latest eye candy and effects... so it will not be CPU dependant... as they designed the engine to run on a certain class of video cards(Radeons and above). It is the video card that is holding back games these days...

this makes things so hard.

Ok I was set to buy my ps2, after all GT3, made it all worth it, now this, now I have to put aside my years savings to buy a new video card because my dual voodoo2 isn't supported by win2k and it would probable choke. ofcourse my new video card, wont work on my overclocked celron 300a. so now i need a new board cpu memory. WHY !!!! dont people realize it sucks to play on my computer in my basement i want to go upstairs on my 48" TV. but i still want my network play so i can shoot the heads off all my wayward co-workers

Re:Operation Flashpoint...

[tshak]

Operation Flashpoint... Also uses Ogg Vorbis - except you never saw that as a headline on slashdot.org

Ya, funny how one of the most popular games, based on the most popular FPS game engine, get's mentioned but a far less popular, niche-market targetted game doesn't get mentioned.

Consumers use MP3 because it has integer decoders

[yerricde]

Perhaps this will encourage the semi-tech crowd (the casual gamer type mostly) to use Ogg, and it may filter down in to the main populous who mainly uses mp3 right now.

People still use MP3 because there are pocket-sized MP3 players, and there are pocket-sized MP3 players because efficient MP3 decoder software that uses fixed-point (integer) arithmetic is widely available. The reference Vorbis decoder still uses floating-point arithmetic, which common ARM microprocessors cannot do in real time.

Re:Assult?

[Pxtl]

That's a shame... sounds like those gametypes all use the same maps - 2 bases with 1 "point" at each end, with a point int the middle for the ball to spawn. Boomball is a popular UT mod already - I'm a diehard player of that one - nice that a 3rd party mod is being incorporated into the game, although I prefer it in black flag mode, in which the ball is a graphically a more traditional flag - same gameplay though.

Assault was one of my fave parts of UT - its how I got my brother, who swore he'd never get into mouseaiming into UT. Coop AS was awesome, especially playing sniper on Overlord.

The problem with AS was a tendancy for overcomplex objectives. If they'd just made the maps have big red numbers saying "shoot me" and you have to shoot each number in order, then it all would be fine. Maybe include TFC style signs on where everything is. Instead you had to have already played the map to know the objectives - not good for newbies. DOM was similar, it was impossible to find the map points, and you never knew which name referred to which point.
