Recently I’ve created a post about how id Software will no longer use OpenGL as their primary graphics API for game development. Here’s John Carmack’s response to the rumors:
There is certainly no plans for a commercially supported linux version of Rage, but there will very likely be a linux executable made available. It isn’t running at the moment, but we have had it compiled in the past. Running on additional platforms usually provides some code quality advantages, and it really only takes one interested programmer to make it happen.
The PC version is still OpenGL, but it is possible that could change before release. The actual API code is not very large, and the vertex / fragment code can be easily translated between cg/hlsl/glsl as necessary. I am going to at least consider OpenGL 3.0 as a target, if Nvidia, ATI, and Intel all have decent support. There really won’t be any performance difference between GL 2.0 / GL 3.0 / D3D, so the api decision will be based on secondary factors, of which inertia is one.
Somehow I keep getting back on this topic. Maybe it’s because of the excitement that was involved with the features promised by the idTech 5 engine as presented in the earlier QuakeCon demo.
Today was one of those exciting days for me. I just finished watching a two part video commentary on the development aspect of idTech 5 that was posted on GameSpy. A third video is an interview with John Carmack on the changes that will be occurring within id Software and other issues. The two commentary videos feature commentaries by John Carmack and Matt Hooper from id Software.
Keep in mind that the “lag” that you might notice is because you’re viewing a technical demo of an unfinished product. Another thing that might be worthy to notice is that the OpenGL API is no longer being used as primary graphics API, yet the company is moving towards DirectX as their primary API.
The first video is presented by John Carmack and is about the development of idTech 5 and Rage. The backdrop for this video is pretty much continuous, so you might want to look away to avoid insanity. He speaks about graphics development, Enemy Territory: Quake Wars and other things that might be interesting to developers.
The second video introduces Matt Hooper as a secondary host and talks more about the tools and assets given to the level designers and artists in idTech 5. For an unreleased product, it looks amazing. There seems to be a great (if not massive) improvement over older tools such as GtkRadiant by having a more intuitive user interface. But you can judge for yourself below by watching the videos attached to this post.
The third video announces a new “game” or adaptation of the existing Quake 3 code base and create a free to download online game, hear all about it in the third video.
Edit: as of 2023, it seems that these videos have been lost to the ravages of time.
If you’re an American citizen or resident and you’re not aware of this issue, keep reading. Otherwise, take action. Links follow.
The Internet is the “Information Highway.” It provides unlimited information, a myriad of free resources and some commercial resources. Due to an expiration of the “Internet Tax Freedom Act of 1998” we might be hitting some toll-plazas along our routes. If you do not feel comfortable paying taxes for free information, sign up at DontTaxOurWeb.org to take some action. If you want to do more, write your senator, but do it promptly. We’re almost at November 1st.
This could potentially be doomsday for many of us. The main thing that the tax would cause is a limit on information which would hurt everyone. Since a large percentage of Americans use the internet, it is imperative that we keep an international resource out of local hands.
At this moment there are many opposed to internet taxes in the senate but it will not hurt to petition and write your congressman or congresswoman. This needs to be fought, freedom of information is at stake.
John Carmack and the id Software company have always been great supporters of the OpenGL Graphics API. Alas, major development with the API stops here for the game developer.
id Software has been working on a new game engine that would “revolutionize” the gaming industry and provide many advanced features. One of its main features is that it can support a constant 60fps on console systems. It was also announced that their new engine will run on: PC, Mac, Xbox 360 and PlayStation 3. Eh, are we missing something important here?
Linux. Linux has always been a supported system when it came down to games from id Software. Yet according to Todd Hollenshead (id Software), id’s upcoming game “Rage” (which will be using idTech5) will be primarily a DirectX 9 game, not DirectX 10, nor OpenGL. Yet OpenGL will be used for the Mac release of both the engine and the game.
This could mean that OpenGL might become very unattractive in the game development community since there will be one less patron to support its Open cause.
One benefit from all this is that the game will be able to run on the Windows XP platform and not solely on Vista as all DirectX 10 games require. This, of course, is no consolidation for the Linux people who will now have to run the game on Windows.
Finally Microsoft has announced the second version of their XNA Game Studio. The best thing? It will work with all versions of Visual Studio 2005. Finally. Read the full story here.
As a developer (and gamer) you always want the latest gadgets and DirectX 10 seems to be one of these gadgets that you just “need to have”.
But does it justify spending much money for an upgrade?
What does DirectX 10 have that DirectX 9 doesn’t? According to some technology demos - not so much. Ok, some special effects but what about the rest? A game isn’t made out of SFX (although it seems to become a trend).
It turns out that DirectX 10 isn’t only about special effects but defines a new style of next generation technology. Video Card manufacturers are forced to use optimized pathways to support the new industry standard resulting in very fast hardware such as the Geforce 8 series (8800 GTX, 8800 GTS).
One of these features is WDDM which stands for Windows Display Driver Model. WDDM is basically a resource manager for graphics processes. One example of what WDDM does is this: In XP when you switch from one Direct3D application you will receive a DEVICE_LOST exception, which basically means that you can’t run two processes from one GPU. Your application crashes and you’ll have to write X amount of handlers dealing with the exception. According to Microsoft this is now a thing of the past.
Since the Vista desktop is a 3D environment you’d loose your application everytime you minimize. This has now been eliminated. Each GPU process is its own thread (just like in regular programming) meaning that you can have X amount of 3D processes running without the need for special handlers.
Also in the same category is improved crash handling that comes with DirectX 10.
Ok, so that’s neat but I’ll need more to be convinced to switch to DirectX 10 hardware and Windows Vista.
Another feature of WDDM is that if you run out of video memory WDDM can virtualize your System’s memory for video processes. Which - in theory - sounds very cool, but I don’t know if this would cause slowdowns.
Here’s a list of new features
Shader Model 4
Texture arrays
DirectSound is gone, XACT is its replacement
Less load on the CPU - GPU tasks really get processed by the GPU this time
Unified Pipeline Architecture - the Programmable Graphics pipeline (SM 4.0)
No object limit - There is no software limit to how many objects you can add to your scene. The only factor in this is your graphics hardware
Geometry Shaders
Instancing 2.0 - An optimized version of the Instancing technology found in Geforce 6 series up and Radeon 9500 and up
So as a developer is it worth it to upgrade to Vista and DirectX 10 hardware? In my opinion, yes. This is simply the new generation of computer graphics, just because you have to upgrade doesn’t mean is’t evil.
Remember when you upgraded from your TNT 2 card to a Geforce? Same thing. Yet this time the improvements revolve more around the pipeline than the actual quality of the image.
I guess writers have this, but now I have it with coming up with new programs. I just can’t think of anything. I’ve been wasting my time reading many programming books on Agile, Design Concepts etc. but that didn’t give me any ideas either. Some knowledge, yes, but inspiration, no.
This is probably one of the coolest ideas that I’ve seen on the Internet in a loooong long time. Google Music Trends is a small program that you download that interacts with your music player and uploads statistics to Google. At the moment the most listened to song is “In the end” by Linkin Park. Of course this has to change ;)
In November of last year, NVIDIA released its latest flagship graphics card chipset, the 8800 / G80. This chipset featured the first full featured DirectX 10 support ever conceived and was (still is at the moment) the only DirectX 10 card on the market.
So when will the other giant, ATi, catch up? According to rumor, ATi is planning to release its latest chipset (R600) in the first quarter of 2007, more precisely an early March launch.
But did ATi push its launch too far back or did NVIDIA jump the bullet on this one? Some say that ATi is holding back for a reason so they can improve their technology and beat NVIDIA performance wise. Others say that ATi didn’t expect NVIDIA to launch this early and is trying to throw together a product too fast. The latter, I personally don’t believe.
ATi has been a major player in graphics technology for a while, so it would be a strange decision to underestimate DirectX 10 and continue focusing on their X1900 technology. I think we can safely assume that ATi is preparing its product to perform to the fullest and maybe be waiting for better software support in Vista - something that NVIDIA has been lacking.
Also, what good is a DirectX 10 card if there are no DirectX 10 games out yet? Again, some say that the 8800 is simply “the best DirectX 9 card out there that happens to have DirectX 10 support.” Yet according to hardware tests on TomsHardware.com, the ATi X1950 XTX stands above the card with full head and shoulders.
So what can we expect in the near future from these two graphics giants? In my opinion (Nostradamus style), ATi will launch the R600 chipset and will make the G80 look like something from 1999 performance wise. The 8800 GTX will get a successor soon enough that will compete with the R600 and I think that ATi will get you more value for the money, as is happening with all AMD and ATi products lately (same company).
I was eagerly looking into buying a G80 or 8800 but I have a feeling I’ll be regretting it within the span of one month. After all, the G80 is already 4 months “old”.
