The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards.DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display.
AMD Eyefinity is a brand name for AMD video card products that support multi-monitor setups by integrating multiple (up to six) display controllers on one GPU. [1] AMD Eyefinity was introduced with the Radeon HD 5000 series "Evergreen" in September 2009 and has been available on APUs and professional-grade graphics cards branded AMD FirePro as ...
The main competing factor was the price of hardware and raw performance in 3D computer games, which is greatly affected by the efficient translation of API calls into GPU opcodes. The display driver and the video decoder are inherent parts of the graphics card: hardware designed to assist in the calculations necessary for the decoding of video ...
The Steam interface allows for user-defined shortcuts to be added. In this way, third-party modifications and games not purchased through the Steam Store can use Steam features. Valve sponsors and distributes some modifications free of charge; [132] and modifications that use Steamworks can also use any Steam features supported by their parent ...
With an AMD graphics card, they found that all ran at considerably fewer frames per second on SteamOS, and Left 4 Dead 2 stuttered, which they attributed to a device driver problem. With an Nvidia graphics card, they found that Metro: Last Light ran at a slightly higher frame rate and Dota 2 broke even.
Once again, a GPU can be either integrated or dedicated. Video Memory is built-in RAM on the graphics card, which provides it with its own memory, allowing it to run smoothly without taking resources intended for general use by the rest of the computer. The term "Video" here is an informal designation and is not intended in a narrow sense.
use a complete (or partial) hardware implementation of a video compression or decompression algorithm; it has become very common to integrate such ASICs into the chip of the GPU/CPU/SoC and therefore abundantly available; for marketing reasons companies have established brands for their ASICs, such as PureVideo (Nvidia), Unified Video Decoder ...
Nvidia Optimus is a computer GPU switching technology created by Nvidia which, depending on the resource load generated by client software applications, will seamlessly switch between two graphics adapters within a computer system in order to provide either maximum performance or minimum power draw from the system's graphics rendering hardware.
