All this noise is nice and all, also it's a good thing we move forward, but what applications and/or games do you know that are using OpenGL 4.0? Is ATI again first to support something that nobody is using to code anything at the moment?
If nobody gives hardware support in the first place, who on earth will code anything?
OpenGL is used in quite a few games and that includes pretty much all the games that can run on Macs, WoW included.
OpenGL 4.0 is a new extension added which is never a bad thing.

No word of which cards it's supported on? I assume all ATI's DX 10.1+ cards.
Radeon HD Series gives you OpenGL 3.3
Radeon HD 5000 Series and above gives you OpenCL 4.0

OpenGL USED to be the standard for video games, and practically every 3D desktop application until a little company called Microsoft came along an introduced DirectX. They promised a robust API, more functionality and closer integration with the OS layer as an enticement, which most game developers bought into, albeit slowely. The other part of it was the ease of code porting to other MS devices/operating systems.

OpenGL was/is open source, so the developers of it weren't working for the profit part of it like M$. OpenGL is somewhat extensible... adding new shader models is possible. With DirectX, you are totally at the whim of M$.

If you want to see a quick, simple comparison of OpenGL to DirectX, install Google Earth. There is program menu option to start it in OpenGL or DirectX. Ironically, I have to use OpenGL to run Google Earth, as it will crash often using DirectX

I was talking about OpenGL 4.0, not the past versions, I know a few things older versions of OpenGL are used for (Adobe CS4 for example), but I don't know of any things that use OpenGL 4.0... And what exaclty does this version bring new to the table as opposed to the older versions?

I had the 10.3 drivers but without the OpenGL update. Cinebench has a OpenGL benchmark. I was only scoring mid 19FPS @ 2.8GHz. I installed the OpenGL 4.0 update (beta) and ran the benchmark and my system is running all stock now (2.6GHz) and my FPS jumped to 36FPS. So atleast in that benchmark it proved to be a performance gain. Now Heaven benchmark on OpenGL had problems. Some scenes were just black. I believe scene 10 and 12 were solid black with a few others having problems with solid black areas.

since sasqui brought it up, i'll cover it in one post so we dont need to go off topic:

openGL was king for graphics. it seemed to be the one for hardware acceleration, back when directX was still used for software.

Things changed however, because directX stopped being all about direct draw (2D) and became a 'bundle' - you got 2D (directdraw) 3D (direct3D) audio (directsound) input (directinput) and so on. Coding for openGL may have given you broarder support and potentially better work, but sticking with directX (and shafting linux/mac) made it easier, since you could get everything you needed in the one package - not just the video component.


Lately, people are just making directX games and swapping direct3D for OpenGL - which is why theres not many ports for other platforms. (they have to go to effort for input, sound, etc)

That was going to be my question. A new api is great and all, but what is out there that uses OGL4 that I need to worry about the drivers right this moment?

Nope, OpenGL isn't open-source, never was. The "Open" in OpenGL refers to open-standards, where each GL vendor (such as NVIDIA, ATI, etc.,) is free to make his own additions (GL extensions).

DX11 graphics on XP? noice!
To bad there are no good games that are using OpenGL. The old stuff from ID doesn't count since they use either OpenGL or DX9...

Nope, OpenGL isn't open-source, never was. The "Open" in OpenGL refers to open-standards, where each GL vendor (such as NVIDIA, ATI, etc.,) is free to make his own additions (GL extensions).

OpenGL (Open Graphics Library) is a standard specification defining a cross-language, cross-platform API for writing applications that produce 2D and 3D computer graphics. The interface consists of over 250 different function calls which can be used to draw complex three-dimensional scenes from simple primitives. OpenGL was developed by Silicon Graphics Inc. (SGI) in 1992[2] and is widely used in CAD, virtual reality, scientific visualization, information visualization, and flight simulation. It is also used in video games, where it competes with Direct3D on Microsoft Windows platforms. OpenGL is managed by a non-profit technology consortium, the Khronos Group.

The OpenGL standard allows individual vendors to provide additional functionality through extensions as new technology is created. Extensions may introduce new functions and new constants, and may relax or remove restrictions on existing OpenGL functions. Each vendor has an alphabetic abbreviation that is used in naming their new functions and constants. For example, NVIDIA's abbreviation (NV) is used in defining their proprietary function glCombinerParameterfvNV() and their constant GL_NORMAL_MAP_NV.

what's the most recent game to use OpenGL? I thinking it would be nice to use two 4890's since they are getting dirt cheap for DX11 like graphics.

for "DX11 like" do you mean... DX10?

Well, the HD 5000 series are the first AMD GPUs with official tessellation support, but a tessellator has been built into AMD GPUs since the R600 (in fact, it even went into the x360 Xenos GPU). From what I've read (it obviously will never be verified) is that the original DX10.0 spec was to include tessellation (hence why AMD included it). However, nVidia didn't add such a component into its "DirectX 10.0 certified" g80 architecture, pressuring Microsoft to lax the API and shove off tessellation (and other features) for DirectX 10.1 and 11.

Using the Linux Unigine OpenGl demo (not sure with the Windows OpenGl renderer), one can use the tessellation option with a pre-RV870 GPU (not an option with DirectX 11). Granted, the framerate takes a nose dive, but it is possible. It is unclear if the Unigine demo is using the built in tessellator of a pre-RV870 GPU (RV770 in my case) or just doing it in software. Because the Unigine demo (and Ubuntu Karmic and newer) require an R600 (or more recent GPU), one cannot see if tessellation would even work with a R500 or older GPU. It'd be cool if someone with a pre-Fermi nVidia GPU tries to run the Unigine Linux demo with tessellation enabled and reports their results.

Finally, one more thing to keep in mind is that many stubborn people (;)) chose to remain running Windows XP, and thus they loose out on the DirectX 10/11 features (regardless if their card is capable of them). Should a game support OpenGl 4.0, it will run in XP with graphics comparable to the same game being rendered on Vista/7 under DirectX 11.

As an aside, I would like to do something I don't typically do, and that would be commend nVidia on their Fermi tessellator. From benchmarks I've seen, Fermi's first generation tessellator eats the R870's tessellator for breakfast, yet AMD has had tessellation experience since the Xenos GPU (as I mentioned before). :respect:

Indeed!! Unreal 2, Unreal Tournament 2, Counter Strike, Half Life, Quake 3 Arena, Serious Sam, and some other games are using the tessellation option when they detect an ATI card. But the feature was actually implemented or coded in game not in the DX driver...I think...

Anyway that feature wasn't called Tessellation but, ATI TruForm

yes! i knew it had another name, but had forgotten it.

Truform has been around for a VERY long time, but since NV never used it, it died off. It was mostly used in openGL games, where it was easier 'per hardware' features in
