Nvidia promises desktop performance for laptops with quadro rtx gpus
Nvidia plans to help everyone with ray tracing, even its competitors. Nvidia is releasing its RTX Global Illumination SDK v1.0 (RTXGI) for use by developers. This is essentially a set of ray tracing tools that will be equipped with tools that provide scalable lighting solutions in games for any GPU that supports DXR.
This will allow game developers to integrate RTX functionality, allowing them to scale the lighting in the game to significantly enhance the lighting effect. This should help those who can't afford or don't want to splurge on giant GPUs; this is generally necessary to enable ray tracing. The
RTXGI SDK will allow developers to access optimized memory layouts, calculation shaders, hooks for game and engine events, and support for multiple coordinate systems.
developers will be able to track and block light from active light sources in the game, which means there is no need to spend countless hours on lighting during the development process. For developers and gamers who enjoy better graphics during the game, this seems to be a benefit.
Tony Tamasi, senior vice president of content and technology at Nvidia, said: "The key advantage here is that it is an extensible SDK that supports low-level hardware that may not have ray tracing to generate global illumination."
He went on to describe the technology. How it works and how game developers can use it: "It works from a very traditional process that game developers are very familiar with, namely light probes. Think of it as baking lighting. But then it allows you to track the light from these light probes, resulting in more accurate lighting, more real-time updates, and you will not get some artifacts that are usually obtained with these light probes, such as light leakage. "
RTXGI will be able to run on any GPU that supports DXR. This means that any graphics card that can run the Microsoft DirectX Ray Tracing API can use it.
Interestingly, AMD is currently developing a DXR line-compatible graphics card that will use RDNA 2 graphics architecture. This shows that Nvidia’s main competitor AMD will also be able to use this new technology, and will also be able to provide scalable global illumination in its products. Oops, it looks like it is no longer Microsoft’s DXR API Or unique to Nvidia's RTX 20 series.
AMD has been working with ray tracing for some time and will be implemented with graphics cards based on the RDNA 2 architecture, which will appear on PlayStation 5 and Xbox Series X later this year.
