Developers from CD Projekt Red made an interesting video discussing new technologies they have implemented in the game. The first is DLSS 3, more specifically image generation, which was added to the game in January. While DLSS 2 only works as a scaling from a lower resolution to a target, DLSS 3 can create a “fake” frame based on the image data, which is then inserted between two classically rendered frames. Upscaling helps in a situation where the graphics card is slow, but image generation can push the FPS beyond what the processor is capable of, which can reach up to double the frame rate at best.
I must say that DLSS 3 is still not perfect, on the one hand it significantly increases latency, which Nvidia is trying to minimize by automatically enabling Reflex technology. However, even the developers at CD Projekt admit that the technology will find its application mainly at higher frame rates, where the increased input lag is not so noticeable. The second problem is the user interface. Whereas upscaling only changes the part of the image specified by the developers, DLSS 3 creates a completely new image and nothing can be left out of it. For example, this can cause artifacts in the user interface that doesn’t look very nice. However, Nvidia is working on fixing these issues.
The second technology that has yet to be added to the game is Path Tracing. The developers first explain that the game mainly uses classic rasterization and with it several lighting techniques, which, however, can never be completely realistic and accurate. Therefore, the game has the ability to enable ray tracing, which allows you to trace individual rays of light in real time, which makes the result much more accurate and generally more pleasant. The technology is very demanding, and so far Cyberpunk 2077 has only had a so-called hybrid form of ray tracing, so the developers just chose a few areas where they wanted to use it, such as shadows or reflections. Path tracing goes one step further, it’s ray tracing in its fullest form. It can track all light rays that hit the surface (direct illumination) as well as all that are subsequently reflected (indirect illumination). The resulting image is very realistic, and all light sources cast shadows.
But this cannot be done without tax. The developers themselves note that this is a “technology preview”. According to them, Path Tracing is the future of game rendering, and this is just an example of what this technology is capable of. Therefore, they say in advance that some errors may appear, and most importantly, a very demanding Cyberpunk 2077 with Path Tracing will be launched. You will need a powerful graphics card and enable scaling and frame generation to get any playable FPS values. However, GPU performance is constantly increasing, and it is likely that in a few years you will be able to play games with path tracing on a regular graphics card.
Ray Traced Mode: Overdrive is coming to PC on April 11 as part of a larger update.
