This is a physical connector that links the graphics cards together and shares data without using any bandwidth on the PCIe slots. The master gathers all the information from the slaves and acts as the final port of call by sending finalized 3D rendered graphics to the display.įor that communication to be possible, Nvidia uses the SLI bridge. It means that one card functions as the master and the others work as slaves. The SLI technology works on a master–slave basis. This way, you won’t have to set up anything manually. Nvidia provides SLI profiles in their driver package for the apps with SLI support. However, not all games and apps support SLI. The SLI technology aims to improve the performance of programs, especially in terms of frames-per-minute count, lighting, shadows, and texture quality. ![]() The algorithm takes the data, breaks it down into smaller pieces, and lets multiple cards work on various elements simultaneously. It incorporates a parallel processing algorithm to achieve this technology. SLI can link two or more video cards that share real-time graphics rendering and produce a single output. Simply put, SLI allows two to four video cards to work together in a single system and share the workload. ![]() Later, Nvidia re-released SLI with new updates in 2004 for use in modern computer systems on certified motherboards based on the PCI Express (PCIe) buses. SLI stands for Scalable Link Interface, first invented in 1999 by the company, 3dfx Interactive. If you want to know how to prepare, install, and test SLI on your computer, this article can help guide you through the process. Nvidia has a feature named SLI that makes it possible to double the power of your graphics card without any hassle. Now, aren’t two graphics cards better than one? As a gamer, digital artist, video editor, programmer, or anyone who needs a powerful gaming computer in terms of graphics, you must know the importance of the graphics card. ![]() Keep an eye out for more news about DLSS in Unity 2021.2 by subscribing to NVIDIA game development news and following the Unity Technologies Blog. You get the performance headroom you need to maximize ray tracing settings and increase output resolution.Īt GTC 2021, Light Brick Studio demonstrated how stunning Unity games can look when real-time ray tracing and DLSS are combined. From those inputs, DLSS composes a beautifully sharp high-resolution image, to which post-processing and UI/HUD is then applied. Once trained, the model can be integrated into the core DLSS library, the game itself or even downloaded by NVIDIA’s Game Ready driver.Īt runtime, DLSS takes three inputs: 1) a low-resolution, aliased image 2) motion vectors for the current frame, and 3) the high resolution previous frame. We built a supercomputer to train the DLSS deep neural net with extremely high quality 16K offline rendered images of many kinds of content. NVIDIA’s solution is to ray trace fewer pixels and use AI on our dedicated Tensor Core units to intelligently scale up to a higher resolution, and while doing so, significantly boost framerates. ![]() While ray tracing produces far more realistic images than rasterization, it also requires a lot more computation, which then leads to lower framerates.
