It’s here, (Edit: It’s official) haven’t read it yet but here it is:
The OpenGL ® Graphics System: A Specification (Version 3.0 - August 11, 2008)

Let me know what you think of it, thanks nosmileface!
It’s been a while since I posted but this one will make up for it. A messy screenshot of NVIDIA’s 2008 timeline has emerged on Chilehardware (CHW) and reveals that OpenGL 3.0 drivers/implementation will be due in September of this year in a collection called Big Bang II (Big Bang I was SLI).
CHW member KaiserGerhardI has provided a deciphering of the screenshot which provides more information on the contents of the screenshot:
The words which could not be deciphered are marked with question marks. What this means for OpenGL enthusiasts and developers is that we won’t have to attend SIGGRAPH, NVISION or any other meeting for that matter, since this is basically a confirmation on its own.
Now, let’s hope that ATI will also provide an implementation this soon.
NVIDIA officially announced its new line of GPUs today on their website. Two models from the line have been announced, namely the GTX 260 and the GTX 280.
NVIDIA claims that the cards have a 50% performance increase over the Geforce 8800 Ultra (figures anyone?). Below are some highlighted specs for the high-end GTX 280:
| Processor Cores | 240 |
| Graphics Clock | 602 MHz |
| Processor Clock | 1,296 MHz |
| Texture fill rate | 48.2 billion/second |
| Memory | 1GB DDR3 |
| Memory Interface Width | 512 bits |
| Memory Clock | 1,107 MHz |
| DirectX Version | 10 |
| OpenGL Version | 2.1 |
| Card Dimensions (WxHxL) | 2 Slots x 4.376″ x 10.5″ |
I’d love to see a benchmark done on this puppy.
DirectX 11 is to be presented at NVISION 08, click here for details.
Looking at the few mentioned features on the page (tessellation, multithreaded rendering, compute shaders, Shader Model 5), I’d say OpenGL is in big trouble if they want to catch up.
This weekend I took some time out to reformat my development computer in preparation for Windows Vista. I used Vista before but switched back to XP x64 in less than a week’s time. But heck, after a year and a Service Pack, I was willing to take the chance with Vista.
I wanted to take advantage of the DirectX 10 features Vista exposes since they’re not available on XP but was kind of disappointed with the performance of the API in Vista. It seems to me that the samples provided in the DirectX SDK simply run much slower than on XP.
Granted, I bought the most budget oriented GPU that supports DX10 (Geforce 8500GT 512VRAM) but that was simply because of the reason that I want my projects to be able to run on the lowest budget hardware possible while still being able to access DX10-like features. Dell, in fact, offers the 8400 on their laptops and budget desktop PCs, which is a fair share of the market and should be targeted.
Vista itself seems pretty solid so far; it certainly responds better than a year ago and supports all of my hardware and development tools (VS 2008, AQTime, Intel C++ compiler, etc). The big test will be OpenGL: Will it also have performance drops or stay the same? I’ll see tonight.
