Recently, an exciting update known as Ray Reconstruction was introduced alongside DLSS 3.5, offering a plethora of graphical enhancements to the world of ray tracing technology. Notably, DLSS 2 is a prerequisite for enabling Ray Reconstruction, meaning you cannot render at native resolution using DLSS alone. Surprisingly, modders wasted no time in creating a solution that allows Cyberpunk 2077 Phantom Liberty to utilize Ray Reconstruction in conjunction with DLAA (Deep Learning Anti-Aliasing).
Ray Reconstruction is specifically tailored for games employing Ray Tracing, designed to sharpen reflections, such as those seen in puddles, which have previously appeared somewhat blurry.
DLAA, on the other hand, is an advanced zero-enhancement mode of DLSS. It permits games to run at their native resolution while adding anti-aliasing and enhanced details from DLSS, making it one of the most sophisticated algorithms of its kind.
Enhancing Graphics in Cyberpunk 2077 Phantom Liberty
For reasons unknown, NVIDIA initially restricted the use of DLAA alongside Ray Reconstruction. Essentially, DLAA could be used independently of reflection enhancements or Ray Reconstruction, but only when operated under DLSS. This artificial limitation has now been circumvented.
Enter the DLSSTweaks tool, designed to enable DLSS in games that do not officially support the technology. This tool allows users to select the scaling method for each profile and even disable it entirely. Consequently, DLSS can function similarly to DLAA, prioritizing anti-aliasing.
DLAA primarily serves to significantly enhance visual quality, and its integration into Cyberpunk 2077, alongside DLSS, may not be ideal since DLSS already operates by rendering the game at a lower resolution before upscaling it.
To utilize Ray Reconstruction, DLSS 3 is required, and it is compatible with RTX 30 Series, RTX 20 Series, and more modern graphics cards. Note that this technology bears similarities to Frame Generation, exclusive to the RTX 40 Series.
To enable DLAA, you must adjust settings accordingly. Download the DLSSTweaks tool and make the necessary modifications:
- Locate the ForceDLSS option within the INI file, which converts DLSS profiles into DLAA, enabling the game to run at its native resolution. Keep in mind that DLSS operates by rendering the game at a lower resolution before scaling it.
- DLAA profiles now take precedence over DLSS profiles within the game, effectively making DLAA equivalent to having DLSS disabled while preserving anti-aliasing.
Enjoying Ray Reconstruction without Path Tracing
NVIDIA’s approach of bundling technologies has faced criticism, as it can limit accessibility for users with less powerful hardware. Some users have sought workarounds to enjoy new technologies without these restrictions.
Path Tracing is an essential component for Ray Reconstruction within DLSS 3.5. However, it imposes demanding hardware requirements, particularly for 4K resolution and frame rates exceeding 60 FPS, necessitating RTX 4090 and RTX 4080 graphics cards.
A user has discovered a method to utilize Ray Tracing with Ray Reconstruction without engaging Path Tracing in Cyberpunk 2077 Phantom Liberty:
- Launch Cyberpunk 2077 and enable Ray Tracing and DLSS Super Resolution using your preferred settings.
- Exit the game and navigate to %LOCALAPPDATA%\CD Projekt Red\Cyberpunk 2077, then open the UserSettings.json file.
- Locate “DLSS_D,” and change both “value” and “default_value” from “false” to “true.”
- Save the configuration file and set it to “read-only.”
- Relaunch the game and enjoy Ray Tracing with DLSS Ray Reconstruction without the need for Path Tracing.
