Cyberpunk 2077 will make use of DLSS 2.0 and other ray tracing techniques

It may be time to start saving up cash for a new GPU as Cyberpunk 2077 aims to push the limits of real time graphics with ray tracing and DLSS 2.0 support.


As if the building hype for CD Projekt Red’s Cyberpunk 2077 wasn’t already reaching a critical mass, the recent media blitz for the game has confirmed that the PC version of the game is going to look really good. In addition to all the regular graphical features and tricks that the Polish developer has been working on since the release of The Witcher 3: Wild Hunt back in 2015, Cyberpunk 2077 will be the first game from the studio to make use of next-generation ray tracing effects to enhance realism and immersion. Additionally, owners of NVIDIA RTX-enabled graphics cards will be able to enjoy improved performance thanks to the implementation of DLSS 2.0, an A.I.-powered upscaling technique.

With the debut of DirectX Ray Tracing (or DXR) back in the second half of 2018, game developers have been able to make use of hardware-accelerated graphical effects made possible with ray tracing. NVIDIA’s Turing architecture-based RTX graphics cards were the first consumer graphics cards to have silicon dedicated to powering these effects with the help of Microsoft’s DXR API in DirectX 12. AMD’s upcoming RDNA 2-based GPUs will also offer hardware acceleration for DXR, allowing owners of each brand to take part in the fun.

Cyberpunk 2077 will use multiple ray tracing effects to bring its gritty, dystopian open world to life. 

  • Ray-traced ambient occlusion - Ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting. The result is a diffuse shading effect that darkens enclosed and sheltered areas and enhances the rendered image's overall tone. In Cyberpunk 2077, ray-traced ambient occlusion additionally can be used with local lights to approximate local shadowing effects where shadows are missing.
  • Ray-traced diffuse illumination - This technique is used to capture sky radiance as well as emissive lighting from various surfaces, which is difficult to achieve with traditional rendering techniques. 
  • Ray-traced reflections - In Cyberpunk 2077, ray-traced reflections are used on all surfaces and can trace ranges for up to several kilometers. They are present on both opaque and transparent objects to simulate the way light reflects from glossy and metal surfaces by tracing a single bounce of reflection rays against the scene. This includes smooth natural mirrors like window glass, but also rougher surfaces like brushed metal. Unlike screen space techniques which can only reflect what’s on-screen, ray-traced reflections incorporate the entire scene around the character, and can accurately represent objects outside the camera view or facing away from the camera.
  • Ray-traced shadows - Cyberpunk 2077 preview supports directional shadows from the sun and the moon. These shadows aim to be physically accurate and even account for light scattering from clouds. Shadows may be enhanced in the final release to support other types of light sources where it is needed.

The use of DLSS 2.0 will be exclusive for NVIDIA RTX graphics cards. It uses the power of neural networks to intelligently upscale supported games in real-time. For example, a game can be rendered at a native resolution of 1920x1080 and DLSS upscaling will allow it to have the appearance of a 2560x1440 image. While ray-traced effects can offer near photorealism, they have never been used for real-time rendering due to how computationally expensive they are. DLSS upscaling will help to alleviate much of the performance hit associated with using such effects so players won’t need to compromise performance for image quality. DLSS 2.0 first debuted with The Foundation DLC for Remedy’s Control.

These new features are expected to be ready in time for Cyberpunk 2077’s launch in November, though some games in the past have released with DXR features arriving later on. For more information about the DXR features in Cyberpunk 2077, check out NVIDIA’s guide.
