Here is the list of OpenGL extensions supported by Catalyst 8.6 drivers for the Radeon X1950XTX under Windows XP SP2 32-bit.
Compared to the Radeon HD 3870, there are five extensions in less:
The GL_ARB_texture_non_power_of_two extension is an important missing. Is it a graphics driver or a hardware problem?

Expreview has published an interview with FutureMark’s vice president Oliver Baltuch. This interview is a little special since questions are asked by Expreview’s readers.
Read the complete interview HERE.
Question: There’s some points we have found that 3DMark lacks, for example, OpenGL benchmark, Sound Card features test, special test for mouse and keyboard (this will be great for hard-core FPS fans )
Answer: ID and the OpenGL committee already make a great benchmark for OpenGL, Quake and Viewperf. The others are covered by internal tests at manufacturers.
Question: Why named “Vantage”?
Answer: As a benchmark, we have a unique Vantage point from which to view the competition. Also, I wanted a V to go with Vista.
The NVIDIA GTX 280 is easily the fastest gaming GPU at the moment and we thought we’d find out how well it does in a dual card setup. From past experiences, we’ve seen that SLI or Crossfire add quite a bit of overhead (SLI especially) and doubling the GPUs certainly doesn’t result in doubling the performance- far from it actually. We already had nVidia’s reference card and thus, when we received the ASUS GeForce GTX 280, we wanted to see how fast can it get with an SLI setup.
Read the complete review HERE.
As expected, the drivers aren’t quite ready for SLI. Games like ET: Quake Wars and Half Life 2 Episode 2 perform worse in an SLI setup on the GTX 280 than with a single card.
Conclusion- At the moment, a single GTX 280 is a much better option that two. With driver optimizations, this could change but certainly not for now.
GLM is a header only C++ math library based on GLSL specification so that if you know how to use GLSL, you know how to use GLSL types and functions: They are the same, same behaviors, same rules. Mostly all GLSL specification have been implemented except texture related issues.
GLM handle all vector and matrix types, GLSL conversions, swizzle operators, the math function library, etc… Beyond the GLSL features an extension system based on GLSL extension system is available. It provides to GLM lot of features like quaternion, matrix transformations, splines, intersections, number precisions, euler angles and various useful functions.

Microsoft will start talking about DirectX 11 in less than two weeks. his conference takes place on the 22 and 23 July in Seattle, Washington.
The big feature of DirectX 11 is tessellation / displacement while we also heard that multithreaded rendering and compute shaders are part of it. DirectX 11 also brings shader model 5.0 but we don’t know many details about it.
It looks like DirectX 11 will stick to rasterization as there is no any mentioning of Ray tracing support.
mvktech.net has has just released a new version of NVIDIA BIOS Editor (NiBiTor) software. NiBiTor is the original and definitive BIOS tweaker that supports the latest NVIDIA graphics cards, and which is updated on a regular basis. NiBiTor allows graphics card enthusiasts, or the hardcore overclockers to have full control over some advanced features and functionality found on firmware of supporting cards.
Mountain House (CA) – You gotta love this industry. 12 days ago, we reported about a website making progress in getting Nvidia’s CUDA platform and PhysX to run on ATI Radeon cards, which Nvidia denied would be possible. Some even claimed that such a tool was a planned hoax. Now we are told that developer Eran Badit has not only been invited to join Nvidia’s developer program, but has also been offered hands-on help. Here is an update to a fascinating story that may soon bring PhysX support to your Radeon graphics card.
Read the rest of the story HERE.

AMD GPU Clock Tool is an overclocking and monitoring tool from AMD and allows you to manage clocks frequencies of all Radeon-based cards.

OpenGL apps running inside a Virtual Machine (VM) can use VMGL to take advantage of graphics hardware acceleration. VMGL can be used on VMware guests, Xen HVM domains (depending on hardware virtualization extensions) and Xen paravirtual domains, using XVnc or the virtual framebuffer. Although not tested, VMGL should work for qemu, KVM, etc. VMGL is available for X11-based guest OS’s: Linux, FreeBSD and OpenSolaris. Finally, VMGL is GPU-independent: we support ATI, Nvidia and Intel GPUs.
Roughly speaking, OpenGL up to version 1.5 is supported with the following exceptions:
- OpenGL 1.2 imaging functions related to histogram, min/max, convolution and colortables (like you really needed them…)
- Display lists aren’t fully conformant: GL_COMPILE_AND_EXECUTE mode may not work reliably, specifically if there is a glGet* call between glNewList and glEndList which gets state that was set by a previous command compiled/executed inside the display list.

Moi (Moment of Inspiration) version 2.0 beta, a new 3D modeling software for designers and CG artists has been released. MoI’s sleek intuitive UI blends a fluid easy workflow with powerful tools, making it the perfect choice for someone who has been frustrated with the complexity of existing tools. MoI is also a fantastic complementary 3d tool for a polygon-based artist since its CAD toolset and advanced boolean functions enable extremely rapid creation of mechanical or man-made type hard surface 3d models. The icing on the cake is MoI’s unique polygon mesh export that generates exceptionally clean and crisp N-Gon polygon meshes from NURBS 3d models.

Tommti-System has released a patch that allows ATI users to run the NVIDIA Medusa demo(GT200) on Radeon-based graphics cards.
Applying the patch
* download the Medusa demo and install it.
* download the patch on Tommti-System and copy the patcher.exe into Medusa\bin directory
* run patcher.exe – Medusa.exe and MedusaLoading.exe will be patched and backed up
* now you only new a nvcpl.dll file from a nvidia driver and copy the nvcpl.dll into Medusa\bin
Getting the nvcpl.dll
* download an nvidia driver (You can check the 175.80 leaked driver here)
* extract all files
* open a command promt and go to the extraction directory
* run expand nvcpl.dl_ nvcpl.dll from the command line
* now you have a nvcpl.dll in the exctraction directory, copy it to Medusa\bin

Recently NGOHQ.com managed to get PhysX running on a Radeon HD graphics card and here’s a little update on the project.
I would like to update you about what’s going on. First, we were very pleased to see so many users and readers have applied to our Beta Test Program! To be specific: 191 users, 5 spies and 2 double agents have submitted applications during the last week. Those that will be chosen will be informed early before the beta is available – we can’t still point to “when” at this stage.
The bad news is we still don’t have access to any HD 4800 hardware yet. It is very important for this project to receive AMD’s support on both developer and PR levels. It seems that AMD still is not being cooperative, we get the feeling that they want this project to fail. Perhaps their plans are to strangle PhysX since AMD and Intel have Havok. We truly hope this is not the case since “format wars” are really bad for the consumers (For example: Blu-ray vs. HD-DVD).
Before we get to the good news, I’m going to ask you to hold on to something steady as some of you are going to feel a bit dizzy after you hear this. The truth is… Nvidia is now helping us with the project and it seems they are giving us their blessings. It’s very impressive, inspiring and motivating to see Nvidia’s view on this. Why they help us? My best guess would be: They probably want to take on Intel with CUDA and to deal with the latest Havok threat from both AMD and Intel.
Some other good news, we are getting a lot of help from cool journalists like Theo Valich to address the HD 4800 access issue. I can confirm that our CUDA Radeon library is almost done and everything is going as planned on this side. There are some issues that need to be addressed, since adding Radeon support in CUDA isn’t a big deal – but it’s not enough! We also need to add CUDA support on AMD’s driver level and its being addressed as we speak.
Sapphire has always offered the most influential ATI graphics products available, and the new Radeon HD 4850 is no different. Although it still uses GDDR3 clocked at 993 (1986 MHz DDR), unlike the 4870 version that is decked out with GDDR5, the Sapphire 100242L model offers 24x custom filter anti-aliasing (CFAA) on its 625 MHz 800-core RV770 GPU. Benchmark Reviews tests the Sapphire Radeon HD 4850 graphics card against the closest competition, and even compare CrossFireX performance in this performance review.
