Hot on the heels of news that DLSS 3.5 Ray Reconstruction can be made to work with DLAA (DLSS at native resolution) using a DLSS-modding utility, we're coming across yet another hack. This one gets you to use DLSS 3.5 Ray Reconstruction on Cyberpunk Phantom Liberty without the need for Path Tracing, and using the game's regular ray tracing technology. Path tracing is very hardware intensive feature, and in our testing, we've only been able to get playable frame-rates at 4K Ultra HD using the two fastest GPUs in the market, the RTX 4090 and RTX 4080. A user on Reddit discovered how to get Phantom Liberty to use regular ray tracing with Ray Reconstruction. We don't know who the original author of this hack is, but it was re-posted to Reddit by Daemoni73. Here are the steps:

• Launch Cyberpunk 2077, enable Ray Tracing and DLSS Super Resolution (in other words apply your preferable settings).
• Exit the game and go to your %LOCALAPPDATA%\CD Projekt Red\Cyberpunk 2077 and open the UserSettings.json file.
• Search for "DLSS_D", set the "value" and "default_value" from "false" to "true".
• Save the config file and set it as "read only".
• Launch the game and play with Ray Tracing and DLSS Ray Reconstruction.

This should make the game less hardware intensive in my opinion
