Cyberpunk 2077 uses real-time ray tracing for ambient occlusion and diffused illumination

Earlier this week, we informed you about Cyberpunk 2077 supporting real-time ray tracing effects. And even though NVIDIA did not reveal any additional details, PCGamesN has reported that CD Projekt RED currently uses RTX for ambient occlusion and diffused illumination.

As PCGamesN noted, the ray-traced ambient occlusion solution adds a “little complementary depth to the scene.” Obviously the ray-traced ambient occlusion is better than SSAO, however it remains to be seen whether the difference between HBAO+ and ray-traced AO is that big visually.

On the other hand, diffused illumination is said to be the feature that most gamers will notice when they enable the RTX effects. It is said that this effect accurately portrays the way light reflects from one object and illuminates others around it.

For example, pay close attention to the reflected lights on the floor in the header image. These reflections are calculated via ray tracing and are the highlight (at least for now) for Cyberpunk 2077.

What’s really disappointing here is that these ray tracing effects offer a light improvement to the overall image, at least in the E3 2019 demo that was showcased using them.

As PCGamesN reported:

“But overall the implementation has been a light touch, at least so far in the game’s development. CD Projekt Red has been selective over where and when ray tracing is used, carefully crafting the demo environment to limit its scope.”

Cyberpunk 2077 releases in April 2020 so it will be interesting to see whether CD Projekt RED will decide to go bananas and take advantage of ray tracing (instead of simply using it to add an extra layer of polish).

    1. Always good to have a few more tricks and shadows other than trimming, To make things look bigger! lol

  1. They better be pretty careful of how they use RTX aka DXR effects in this game. Or it will have 1000+ memes made on launch.

      1. 1000+ more on the way if they blow it with this game… Kinda like all the attention witcher 3 had after the gameworks disaster that needed a lot of patches

        1. ray tracing is already a success, there’s no flopping. more and more games will be using it in the future.

          1. i’d be typing lol if i couldn’t afford anything other than a gtx 750 as well.

        1. i don’t agree with that, i smile at some of the rtx memes as well but if you want to see a real poor peasant scroll down a little bit.

  2. >What’s really disappointing here is that these ray tracing effects offer a light improvement to the overall image

    How can you say that when they did not show any comparison with it on/off?

    Either way, the difference will be most drastic in exterior environments with sun/moonlight.
