nVidia GTX 260 SLI motherboard has come to the market with many advanced features making it perfectly ideal for graphic processing and reduced power consumption. This hybrid SLI was introduced after the launching of nVidia’s 700 and 8000 series motherboard chipsets. nVidia GTX 260 SLI integrates augmented graphic processing power through GeForce Boost in the chipset. An onboard graphics chip together with a supported discrete video card make this nVidia with increased capabilities comparing with the traditional multi-GPU configuration.

nVidia has proved its capabilities and showed less hungry for power through its more modern, traditional multi-GPU setup, which helped the chip to enhance the system’s graphical horsepower. The nVidia GTX 260 is a new chip set in the market competing with its predecessors and is relatively expensive. But comparing the visual comfort and the great features offered by GTX 260, the bit high cost is worth shouldering to get a grandeur videocard.

nVidia GTX 260 features a 576MHz, 192sp processing core with 896MB of 1000MHz GDDR3 linked through a 448bit interface. This hybrid SLI comes as a white-box, refurbished unit. External appearance of the box is not eye catching, but it contains a praise worthy important stuff, the hardware platform needed to link the two cards via nVidia’s Scalable Link Interface, or SLI.

You must have already had a best performing single card and there can be a desire in you to have a card with more graphical horsepower, then the best option in front of you is nVidia GTX 260. Comparing three factors performance, efficiency and cost nVidia GTX 260 stands in the front for any user to enjoy the great features of this modern tech savvy video card.

It is better to upgrade your card to a relatively low priced nVidia GTX260. This will improve the speed and efficiency and you will feel the difference. Your gaming experience is going to change with nVidia GTX 260 SLI.

EVGA’s GeForce GTX 285 Mac Edition has given Mac users an amazing and handy GPU option to buy the video card upgrades from online vendors including Apple.com. Prior to the release of EVGA’s GeForce GTX 285 Mac Edition, the video card upgrades were from either NVIDIA or ATI and Apple did not support the upgrade market. It is a real worth move form the Apple.

Apple has come out lately with GPU releases which are better in handling the upgrading process. The Radeon HD 4870 and the 8800 GT are build-to-order the much wanted GPU options directly from Apple. Importantly now Apple officially supports conventional PC video cards helping the user to dump the ROM from the Mac and hack the PC cards to become Mac editions.

GeForce GTX 285 Mac Edition is a compact hardware just identical to what you get when you buy a PC card. The prime difference comes in the packaging and firmware. You can use these cards in the Mac Pro. Typically additional PCIe power connectors are not required in the standard video card in any Mac Pro. When you intend to upgrade to a more powerful video card, you may require one or two cables to connect the small PCIe power connectors on the Mac Pro’s motherboard and also to the connectors on the video card. All these required cables are in the GTX 285 Mac Edition box.

GTX 285 Mac Edition has major change in firmware. The firmware has a few EFI hooks to make your PC Video card to work under OS X. PC specific cards do not have EFI hooks. This will enable you to do Binging or Googling and to find ROM dumps suitable for other PC cards which can enable Mac operation. GeForce GTX 285 with firmware can be used without any modifications to POST and function under OS X.

The price is fixed at $449.99. It is bit high compared to other Video upgrading cards. But comparing the price of the hardware and the price for two extra cables Mac Edition Box has a moderate price. The box comes with a lone DVI to VGA adapter, a pair of power cables and a driver CD. It has two dual-link DVI outputs and has no support for mini-DisplayPort. In brief EVGA’s GeForce GTX 285 Mac Edition is worthy of buying it and is perfectly ideal for all Mac owners.

Let’s start with a quote from Nvidia’s senior developer Jeff Brown:
“Thousands of applications are being created today that harness the phenomenal power of GPUs, a clear sign that GPU computing has reached a tipping point. The world of computing is shifting from host-bound processing on CPUs to balanced co-processing on GPUs and CPUs. NVIDIA application acceleration engines arm developers with the tools they need to further revolutionize both real-time graphics and advanced data analysis.”

In short, with this new engine, you are invited to the new world of technology Optix Ray Tracing. It is the state of the art technique for creating an imaging by perfectly tracing the light rays passing through pixels in an image plane. Nvidia Optix Ray Tracing engine is designed and developed based on this technology which can produce a very high degree of photorealism with amazingly perfect style. Of course this perfection comes with higher computational cost. Ray tracing is ideal for all types of applications where time is not a critical factor like in still films and videos and not perfectly suited in applications where time plays a critical role like in computer games. The important advantages of the ray tracing come in optical effects. It can simulate all types of optical effects like scattering, reflection, refraction and chromatic aberration.

The NVIDIA OptiX engine, a programmable ray tracing pipeline enabling software developers, brings high levels of realism their applications by the proper programming with traditional C language. The OptiX engine makes the ray tracing faster with the tapping of the amazing potential of the amazing powers of the NVIDIA Quadro parallel processors. The Nvidia Optix Ray Tracing engine uses wide range of disciplines like optics simulation, photorealistic rendering, radiation research, automotive styling, acoustical design and volume calculations.

Fantastic way to fool your brain is old well known technology in a totally new way of designing. Do you remember VFX helmets, where games can be placed stereo 3D?? It was amazing but the technology was pretty prehistoric, running games like doom 2 or quake 1:) And now I got a fantastic pleasure to introduce you a fantastic new product with nVidia logo - brand new 3d glasses. And so nVidia has teamed up with Samsung and created a 3d binoculars with high quality 120 Hz LCDs, with all new 3D stereo shutter glasses technology. 120 Hz are very important - that your eyes will be no tired. NVIDIA has its finish in the driver support and go to a state where it is really good. Alongside this, it redesigned the approach to the game experience. These remarkable shutter 3D glasses are wireless and rechargeable, games that rely on new drivers automatically kicks-ass in 3D mode and next to that NVIDIA wanted to find a really cool game.

It is now 2009, a lot in the stereoscopic market segment has changed and sure, a lot hasn’t. With the new GeForce 3D Stereo Vision slowly kits now available here in Europe, contained a good time to look at them. We asked NVIDIA to send the complete package, with a 120Hz Samsung LCD monitor and shutter glasses kit for. I got nothing more to say - they’re amazing!

A MIP mapping is a type of graphics effects filter that is used to create an semblance of depth in computer design environment. It makes a two-dimensional (2D) samples of a three-dimensional (3D) graphic surrounding. MIPmapping id being used with texture displaying, more of that MIP mapping features multiple visualizations of a each graphic texture map made in different resolutions to show surface textures with an illusion of distances from the user point of view. It simply creates the largest available scaled image and placing it inside the front environment and dynamically placing smaller ones that reaches the farther zones of background area to the same horizon - it depends what level of mip mapping your software/game provides. Every generated image is scaled to feel the difference between what’s close and what is farther - is defined as a MIP map level - higher level means more generated images that builds 3d environment. When the level of MIP mapping is higher, your card performance will be decreased. Besides generating 3D graphics MIP mapping is useful avoiding unwanted scratched edges, these “ragged” borders is called jaggies. Generally speaking mipmapping upgrades the quality level of graphics surroundings by placing various versions of the texture that are minimized more when the 3D depth increases. This graduation of every single mipmap level is dependent on the Texture LOD (Level Of Detail).

MIPmapping and 3d environment

But 3d artificial environment takes more than just MIP mapping to get a proper result, that’s because the texture’s perspective is oriented closer when it gets to the horizon. Therefore the minimized textures are the farther ones from the viewer. The true is that without any graphic filtering of the texture, you can get only a very pixilated image - it is called point sampling. There is a significant rule saying that when the distance from the viewer is increasing, the pixels that are available near the horizontal ones only for representation, that is because the 3d environment runs from the lower zones of the screen to the center.

Take a look at the Mip mapping example above. The left part is done without mipmapping. You might think that it looks sharper in the screenshot here. It is, but without mipmaps all textures flicker with a large amount of noise - this looks awful when the scene is set in motion. Simplifying the Mipmaps are different versions of one and the same texture that is available in various sizes to fit it in a proper place (depth) inside 3D graphic environment. Just try to imagine that you are standing in a long highway and you are focusing on the road texture beginning from your legs to the all way to the same horizon. To secure as much realistic appearance as it possible. The middle lines on our highway which are closer to the viewer must be generated in high details, higher resolution. If you are moving your sight closer to the horizon, the textures gets smaller and smaller. There are situations where details which are closer can be lost due to scaling problem because your graphic card driver doesn’t know which are the most significant details in the texture - it can be avoided by installing a newer driver or lower the level of MIP mapping.

DirectX 10 was available to Windows Vista users only at the time of its introduction, but unfortunatelly, you will not find DirectX 10, being released for the Windows XP operating system. DirectX 10 is deeply linked into Windows Vista OS and we currently do not know about the plans by Microsoft to allow Windows XP to officially support the new DX10. In general, DX10 gives much more generic graphic processing model with lots of flexibility and reliability. This will be very crutial going forward, but right now developers still need to make some limitations on shader length and complexity based on the performance of the hardware that exists. Another thing related with the Geometry Shader is the Stream Out functionality that provides the GPU to recycle graphics files without computing on the CPU. Not only is this a hit of performance, it will also gives completely independant of the CPU for particle systems. Take a look at the DirectX 10 performance tested on two nVidia Cards:

If you want to have a DirectX 10 on your computer you will have to go with Windows Vista as your OS, theres nop possibility to launch dx10 on MS windows XP systems. Because of this we will see an expensive upgrade path associated with the experience of DirectX 10. You will need Windows Vista, DirectX 10 hardware and of course some DirectX 10 coded games, what is totally rediculous, that’s why plenty of gamers are turning into PS3 or Xbox. The question that gamer all over the world are asking is: “Will this very expensive upgrade will have positively impact on my my gaming experience enough to justify the cost?” That has yet to be seen and can only be answered with the games we have yet to play. We can however talk about some of capabilities of DirectX 10 with a unknown architecture and answer the question how it can potentially benefits to the gamers. In next reviews we’ll be reviewing later versions of DirectX.
