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] |
Tearing (simulated)
Tearing is the act of breaking apart a material by force, without the aid of a cutting tool. A tear in a piece of paper, fabric, or some other similar object may be the result of the intentional effort with one's bare hands, or be accidental. Unlike a cut, which is generally on a straight or patterned line controlled by a tool such as scissors, a tear is generally uneven and, for the most part, unplanned. An exception is a tear along a perforated line, as found on a roll of toilet paper or paper towels, which has been previously partially cut, so the effort of tearing will probably produce a straight line. Materials vary in their susceptibility to tearing. Some materials may be quite resistant to tearing when they are in their full form, but when a small cut or tear is made, the material becomes compromised, and the effort needed to continue tearing along that line becomes less. Materials can be characterized by standard test methods to measure their tear resistance. There ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-Sync
G-Sync is a proprietary adaptive sync technology developed by Nvidia aimed primarily at eliminating screen tearing and the need for software alternatives such as Vsync. G-Sync eliminates screen tearing by allowing a video display's refresh rate to adapt to the frame rate of the outputting device (graphics card/integrated graphics) rather than the outputting device adapting to the display, which could traditionally be refreshed halfway through the process of a frame being output by the device, resulting in screen tearing, or two or more frames being shown at once. In order for a device to use G-Sync, it must contain a proprietary G-Sync module sold by Nvidia. AMD has released a similar technology for displays, called FreeSync, which has the same function as G-Sync yet is royalty-free. Nvidia built a special collision avoidance feature to avoid the eventuality of a new frame being ready while a duplicate is being drawn on screen (something that could generate lag and/or stut ...

ZX Spectrum
The ZX Spectrum () is an 8-bit computing, 8-bit home computer developed and marketed by Sinclair Research. One of the most influential computers ever made and one of the all-time bestselling British computers, over five million units were sold. It was released in the United Kingdom on 23 April 1982, and around the world in the following years, most notably in Europe and the United States. The machine was designed by English entrepreneur and inventor Sir Clive Sinclair and his small team in Cambridge, and was manufactured in Dundee, Scotland by Timex Corporation. It was made to be small, simple, and most importantly inexpensive, with as few components as possible. The addendum "Spectrum" was chosen to highlight the machine's colour display, which differed from the black-and-white display of its predecessor, the ZX81. Rick Dickinson designed its distinctive case, rainbow motif, and chiclet keyboard, rubber keyboard. Video output is transmitted to a television set rather than a ded ...

Commodore 64
The Commodore 64, also known as the C64, is an 8-bit computing, 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, January 7–10, 1982, in Las Vegas). It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the VIC-20 and Commodore PET, the C64 took its name from its of RAM. With support for multicolor sprite (computer graphics), sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware. The C64 dominated the low-end computer market (except in the UK, France and Japan, lasting only about six months in Japan) for most of the later years of the 1980s. For a substantial period (1983–1986), the C64 had betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Racing The Beam
''Racing the Beam: The Atari Video Computer System'' is a book by Ian Bogost and Nick Montfort describing the history and technical challenges of programming for the Atari 2600 video game console. Content The book's title comes from the fact that the Atari 2600, initially branded the VCS (Video Computer System), did not have a video frame buffer and required the programmers to write each line of video to the TV output, one line at a time. As there were only a limited number of machine cycles in which to do this, the programmers were "racing" a high-speed electron beam across the screen. ''Racing the Beam'' discusses the history of the VCS platform and the design decisions that impacted the types of games that could be written for it. Specific games such as ''Combat'', ''Pitfall!'' and '' Yars' Revenge'' are analyzed from a technical and cultural perspective. ''Racing the Beam'' is the first in a series of books on early video-game platforms and has been cited by modern Atari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raster Interrupt
A raster interrupt (also called a horizontal blank interrupt) is an interrupt signal in a legacy computer system which is used for display timing. It is usually, though not always, generated by a system's graphics chip as the scan lines of a frame are being readied to send to the monitor for display. The most basic implementation of a raster interrupt is the vertical blank interrupt. Such an interrupt provides a mechanism for graphics registers to be changed mid-frame, so they have different values above and below the interrupt point. This allows a single-color object such as the background or the screen border to have multiple horizontal color bands, for example. Or, for a hardware sprite to be repositioned to give the illusion that there are more sprites than a system supports. The limitation is that changes only affect the portion of the display below the interrupt. They don't allow more colors or more sprites on a single scan line. Modern protected mode operating systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benchmark (computing)
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. The term ''benchmark'' is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves. Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems (DBMS). Benchmarks provide a method of comparing the performance of various subsystems across different chip/system architectures. Benchmarking as a part of continuous integration is called Continuous Benchmarking. Purpose As computer architecture advanced, it became more difficult to compa ...

Input Lag
In computers, lag is delay ( latency) between the action of the user (input) and the reaction of the server supporting the task, which has to be sent back to the client. The player's ability to tolerate lag depends on the type of game being played. For instance, a strategy game or a turn-based game with a slow pace may have a high threshold or even be mostly unaffected by high lag. A game with twitch gameplay such as a first-person shooter or a fighting game with a considerably faster pace may require a significantly lower lag to provide satisfying gameplay. Lag is mostly measured in milliseconds (ms) and may be displayed in-game (sometimes called a lagometer). The most common causes of lag are expressed as ping time (or simply ''ping'') and the frame rate (fps). Generally a lag below 100 ms (10 hz or fps) is considered to be necessary for playability. The lowest ping physically possible for a connection between opposite points on Earth crossing half of the planet is 133 ms. ...

Telecine Judder
Telecine ( or ), or TK, is the process of transferring film into video and is performed in a color suite. The term is also used to refer to the equipment used in this post-production process. Telecine enables a motion picture, captured originally on film stock, to be viewed with standard video equipment, such as television sets, video cassette recorders (VCR), DVD, Blu-ray or computers. Initially, this allowed television broadcasters to produce programs using film, usually 16-mm stock, but transmit them in the same format, and quality, as other forms of television production. Furthermore, telecine allows film producers, television producers and film distributors working in the film industry to release their productions on video and allows producers to use video production equipment to complete their filmmaking projects. Within the film industry, it is also referred to as a ''TK'', ''TC'' having already been used to designate timecode. Motion picture film scanners are simila ...

FreeSync
FreeSync is an adaptive synchronization technology that allows LCD and OLED displays to support a variable refresh rate aimed at avoiding tearing and reducing stuttering caused by misalignment between the screen's refresh rate and the content's frame rate. FreeSync was developed by AMD and first announced in 2014 to compete against Nvidia's proprietary G-Sync. It is royalty-free, free to use, and has no performance penalty. Overview FreeSync dynamically adapts the display refresh rate to variable frame rates which result from irregular GPU load when rendering complex gaming content as well as the lower 23.97/24/29.97/30 Hz used by fixed video content. This helps remove stuttering delays caused by the video interface having to finish the current frame and screen tearing when starting a new frame in the middle of transmission (with vertical sync off). The range of refresh rates supported by the standard is based on the capabilities reported by the display. FreeSync can be e ...
