CrossFire ™ Overview 35 CHAPTER 7: Using the Radeon ® X1950 XTX with CrossFire ™ The Radeon ® X1950 XTX can be used as a Slave graphics card in a CrossFire ™ system. For the full system requirements necessary to put tog ether a working CrossFire ™ system, see the CrossFire ™ FAQ.
36 CrossFire ™ Rendering Modes The first three are perfor mance-oriented modes, while Super Anti-aliasing is a quality-oriented mode. Each mode uses a different method for dividing the workload required to render a 3D image across multiple GPUs. Only one mode can be in operation at any given time .
CrossFire ™ Rendering Mo de s 37 SuperTiling has the advantage o f being able to work with practically any 3D application. However, there are a small number of applications where the SuperTiling workload distribution does n ot provide optimal performance.
38 CrossFire ™ Rendering Modes Although Scissor Mode is generally a less efficient means of splitting the workload than using SuperTiling , th ere are a few cases where it can be more efficient. It is supported by CrossFire ™ in order to maximize compatibility an d performan ce.
Super Anti-aliasing Mode 39 The main limitation of this mode is that it cannot be used in appl ications where the appearance of the current frame is dependent upon data generated in previous frames, since AFR generates successive frames simultaneously on d ifferent GPUs.
40 Super Anti-aliasing Mode Some types of textures, especially those with transpar ent portions, can exhibit aliasing that is not removed by MSA A techniques. Another form of anti-aliasing, known as Super-sample Anti-aliasing (SSAA), can be useful in these cases, because it affects ever y pixel in an im age.
Super Anti-aliasing Mode 41 pattern that does a better job of anti-aliasing near-h orizontal and near- vertical edges, resulting in better overall image quali ty. Two of the new Super Anti-a liasing modes use a combination of MSAA and SSAA to achieve the ultimate in im age quality.
42 Super Anti-aliasing Mode.
43 CHAPTER 8: CrossFire ™ FA Q The following are frequently-ask ed questions about CrossFire ™ . For the late st informatio n, please consult th e CrossFire ™ Web site at: ati.
44 5 Which slot does the CrossFir e ™ Master card go into on the motherboard? The CrossFire ™ Master card must go into the primary PCI Ex press ® slot (slot zero) on the motherboard. Note: T o determine which PCIe ™ slot is the primary slot, consult your motherboard manual.
45 T o access and enable CrossFire ™ in Catalyst ™ Control Center, do the following: •C l i c k CrossFir e ™ in Advanced V iew . Then, select Enable CrossFir e ™ . When CrossFire ™ is successfully enabled, all display devices except the one used by C rossFire ™ will be disabled.
46 graphics card. The result is a comp lete frame rendered at up to twice the performance of a single graphics card. 8 How are the graphics cards connected on a CrossFir e ™ system ? The two cards are connected by an external cable.
47 15 How many independent displays can be connected to a CrossFir e ™ system? While CrossFire ™ is designed for optimal use on a single display , it is possible to drive multiple monitors using a CrossFire ™ system when CrossFire ™ is not enabled.

59 CHAPTER 10: Glossary 2D Acronym for “two dimensional,” a term applied to computer graphics that are “flat.” Typical desktop applica tions such as wo rd processors, spreadsheet programs, or .
60 surfaces, allowing game pr ogrammers to include mo re texture and lighting details without affecting performance. Adaptive Anti -aliasing Adaptive anti-aliasing is a technique that applies a com binat ion of multi- sampling (MSAA) and super-sampling (SSAA) on 3 D objects to improve edge smoothness and fine detail.
61 operation is only avai lable in Radeon ® CrossFire ™ graphics cards running Microsoft ® Direct 3D ® and OpenGL ® games or applicati ons. Anisotropic Filtering A technique that preserves the surface de tails of an object as it recedes into the distance by utilizing and blendin g together the object’s texture maps.
62 single display within its exi sting ambient lighting environment, or to bett er color match two or mo re adjacent monitors. Back Buffer A type of offscreen memory used to provide smooth v ideo and 2D graphics acceleration. This techniqu e uses two frame buffers, so the process is often referred to as “double- buffering.
63 Brightness The amount of white or black that i s applied to all colors onscreen. By making the screen “brighter” you are adding more white to it. This sh ould not be confused w ith luminosit y, which measures the actual light l evel emitted from the computer display.
64 Component Video Typically used on DVD players and HDTV systems, component video is a standard Red/Green/Blue (RGB) color signal for televi sions. The signal is split and compressed into separate luminance and color values—luminance (“Y”), red minus luminance (R-Y), and blue minus lu minance (B-Y).
65 beams activate separate red, green, and blue values in various strengths in order to produce a colored image. Dashboard The dashboard is the part of the Ca talyst ™ Control Center used to displa y a graphical representation of the features available in installed ATI hardware and software.
66 DVI Acronym for “Digital Vide o Int erface,” a standard video connection used on many current computer disp lays . There are three types of DVI connections: DVI-A (analog) , DVI-D (digital), and DVI-I (in tegr ated, capable of either analog or digital).
67 Frames Per Se cond In terms of 3D graphics, refers to the rate at which the graphic processor can render new screens per second. Higher rates equals better, more naturalistic performance fo r such things as games set in a 3D environment. Sometimes abbreviated to “fps.
68 HDTV Acronym for “High Definition Tel evision,” a format that produces much greater picture quality than a st andard televi sion, and in a wide-screen format that matches that of a movie theater screen.
69 Keyframe Interpolation This feature is also known as “morphing.” In an animation, a start and end point are picked as the key frames. In a 3D rendering, the start point could have a character with a neutral expr ession, and the end point could have that same character smili ng.
70 flicker-free. The acronym refers to the National Televi sion Systems Committee, which devised this color video standard in 1953. Offscr een Memory An area of memory used to preload im ages so that they can be quickly drawn to the screen.
71 PCI Express ® (PCIe ™ ) The successor standard to the PCI and AGP bus standards, with a significantly faster serial communi cations system, further opening up bandwidth for more communicatio ns between such peripherals as graphics cards and the computer’s CPU.
72 Resolution The resolution of any display is the number of pixels that can be depicted on screen as specified by the number of horizontal rows against the number of vertical columns. The default VGA resolution of many vid eo cards is capable of displaying 640 rows of pixels by 480 col um ns.
73 (HDTV) systems. SDTV systems use the same 4:3 aspect ratio and 480 scan lines to produce a picture as regul ar analog television sets, but digital decoding enhanced of the signal, displa ying a sharper and crisper picture.
74 Super Anti-aliasing A feature that improves image quality by comb ining the results of full- screen anti-aliasing across two graphics cards in a CrossFire ™ configuration. The two graphics cards work on differ ent anti-aliasin g patterns within each frame.
75 textured surface that look s like cloth and wrap it around a 3D sphere, the sphere will now a ppear to have a cloth-like surface. T exture Prefer ence Texture Preference is a feature enabling the user to select the texture quality level for the surface of a 3D object.
76 V ersaV ision ™ An ATI technology enabling accelerated display rotation and scaling. Any desktop can now be rotated 90 degrees left or right, or even 180 degrees, while maintaining the full feature set of other ATI 2D and 3D technologies, such as SmoothVision ™ .
77 capability. It also supports component output support for EDTV displ ays at 480i (interlaced scanning), 480p (progressive scanning ), and for HDTV displays at 720p, and 1080i. V ideoShader ™ HD A feature that integrates pixel-shad ing technology with vid eo filtering and processing functions.
