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.
The dedicated graphics cards consume much more power than integrated graphics but also provides higher 3D performances, which is needed for a better gaming and CAD experience. Following is a list of the TDPs of the most popular CPU with integrated graphics and dedicated graphics cards.
Under Windows 7 and with WDDM 1.1 drivers, DWM only writes the program's buffer to the video RAM, even if it is a graphics device interface (GDI) program. This is because Windows 7 supports (limited) hardware acceleration for GDI [2] and in doing so does not need to keep a copy of the buffer in system RAM so that the CPU can write to it.
In August 2019, Nvidia announced Minecraft RTX, an official Nvidia-developed patch for the game Minecraft adding real-time DXR ray tracing exclusively to the Windows 10 version of the game. The whole game is, in Nvidia's words, "refit" with path tracing , which dramatically affects the way light, reflections, and shadows work inside the engine.
General-purpose computing on graphics processing units (GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).
The article suggested that a PhysX rewrite using SSE instructions may substantially lessen the performance discrepancy between CPU PhysX and GPU PhysX. In response to the Real World Technologies analysis, Mike Skolones, product manager of PhysX, said [ 32 ] that SSE support had been left behind because most games are developed for consoles ...
This makes it possible for C programs to take advantage of a GPU's ability to operate on large buffers in parallel, while still using the CPU when appropriate. CUDA was the first API to allow CPU-based applications to directly access the resources of a GPU for more general purpose computing without the limitations of using a graphics API.
The GeForce 256 is the original release in Nvidia's "GeForce" product line.Announced on August 31, 1999 and released on October 11, 1999, the GeForce 256 improves on its predecessor by increasing the number of fixed pixel pipelines, offloading host geometry calculations to a hardware transform and lighting (T&L) engine, and adding hardware motion compensation for MPEG-2 video.
