Micro Stuttering
__notoc__ Micro stuttering is a quality software bug, defect that manifests as irregular delays between film frame, frames rendered by a graphics processing unit (GPU). It causes the instantaneous frame rate of the longest delay to be significantly lower than the frame rate reported by benchmarking applications such as 3DMark, which usually calculate the average frame rate over a longer time interval. In lower frame rates,Under which frame rate the effects of micro stuttering become apparent varies depending on numerous variables and how sensitive the human test-subject is. The worst-case scenario would be that the frames from all GPUs finish rendering at the same time, in such a case the frame rate perceived by the viewer would be half of the reported average frame rate in the case of a dual-card configuration, and just a fourth in a quad-GPU configuration. when this effect may be apparent the moving video appears to stutter, resulting in a degraded gameplay experience in the case ...

Device Driver
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it). Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface. Purpose The main purpose of device drivers is to provide abstraction b ...

Screen Tearing
Screen tearing is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate. That can be caused by non-matching refresh rates, and the tear line then moves as the phase difference changes (with speed proportional to the difference of frame rates). It can also occur simply from a lack of synchronization between two equal frame rates, and the tear line is then at a fixed location that corresponds to the phase difference. During video motion, screen tearing creates a torn look as the edges of objects (such as a wall or a tree) fail to line up. Tearing can occur with most common display technologies and video cards and is most noticeable in horizontally-moving visuals, such as in slow camera pans in a movie or classic side-scrolling video games. Screen tearing is less noticeable when more than two frames finish r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rendering (computer Graphics)
Rendering is the process of generating a physically-based rendering, photorealistic or Non-photorealistic rendering, non-photorealistic image from input data such as 3D models. The word "rendering" (in one of its senses) originally meant the task performed by an artist when depicting a real or imaginary thing (the finished artwork is also called a "architectural rendering, rendering"). Today, to "render" commonly means to generate an image or video from a precise description (often created by an artist) using a computer program. A application software, software application or component-based software engineering, component that performs rendering is called a rendering software engine, engine, render engine, : Rendering systems, rendering system, graphics engine, or simply a renderer. A distinction is made between Real-time computer graphics, real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or an ...

Jitter
In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery applications it is called timing jitter. Jitter is a significant, and usually undesired, factor in the design of almost all communications links. Jitter can be quantified in the same terms as all time-varying signals, e.g., root mean square (RMS), or peak-to-peak displacement. Also, like other time-varying signals, jitter can be expressed in terms of spectral density. Jitter period is the interval between two times of maximum effect (or minimum effect) of a signal characteristic that varies regularly with time. Jitter frequency, the more commonly quoted figure, is its inverse. ITU-T G.810 classifies deviation lower frequencies below 10 Hz as ''wander'' and higher frequencies at or above 10 Hz as ''jitter''. Jitter may be caused by electromagnetic interference and crosstalk with ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battlefield 3
''Battlefield 3'' is a 2011 first-person shooter game developed by DICE and published by Electronic Arts. It is the sixth main installment in the '' Battlefield'' series and a follow-up to '' Battlefield 2'' (2005). The game was released on Microsoft Windows, PlayStation 3 and Xbox 360 in October 2011. The campaign takes place in various locations and follows the stories of two characters, Henry Blackburn, a U.S. Marine and Dimitri Mayakovsky, a Spetsnaz GRU operative. Development on the game began in 2009 after the release of '' Battlefield 1943''. DICE employed an upgraded version of the Frostbite game engine to present realistic and engaging graphics. An open beta was presented forty-eight hours before it was released to gamers who pre-ordered ''Medal of Honor'' Limited Edition. Following its announcement, ''Battlefield 3'' received much anticipation and hype. The game received mostly positive reviews from critics who praised its multiplayer and graphics, but criticized th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radeon HD 7000 Series
The Radeon HD 7000 series, codenamed "Southern Islands", is a family of GPUs developed by AMD, and manufactured on TSMC's 28 nm process. The primary competitor of Southern Islands was Nvidia's GeForce 600 series (also manufactured at TSMC), which shipped during Q1 2012, largely due to the immaturity of the 28 nm process. Architecture Graphics Core Next was introduced with the Radeon HD 7000 series. *A GPU implementing Graphics Core Next is found on the Radeon HD 7730 and above branded discrete GPUs. *A GPU implementing TeraScale (microarchitecture) version " Evergreen (VLIW5)" is found on Radeon HD 7670 and below branded discrete GPUs. *A GPU implementing TeraScale (microarchitecture) version " Northern Islands (VLIW4)" is found on APUs whose GPUs are branded with the Radeon HD 7000 series. *OpenGL 4.x compliance requires supporting FP64 shaders.

Program Optimization
In computer science, program optimization, code optimization, or software optimization is the process of modifying a software system to make some aspect of it work more efficiently or use fewer resources. In general, a computer program may be optimized so that it executes more rapidly, or to make it capable of operating with less memory storage or other resources, or draw less power. Overview Although the term "optimization" is derived from "optimum", achieving a truly optimal system is rare in practice, which is referred to as superoptimization. Optimization typically focuses on improving a system with respect to a specific quality metric rather than making it universally optimal. This often leads to trade-offs, where enhancing one metric may come at the expense of another. One popular example is space-time tradeoff, reducing a program’s execution time by increasing its memory consumption. Conversely, in scenarios where memory is limited, engineers might prioritize a slower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
