The gaming community has stumbled upon an unexpected discovery in the recently launched Modern Warfare 4 pre-order beta: what appears to be the first implementation of NVIDIA's highly anticipated DLSS 4.5 Ray Reconstruction technology.
Early access for preorders began on August 21st, and within hours, an eagle-eyed Reddit user unearthed evidence of the new upscaling technology hidden within the game files. This marks a significant milestone, as NVIDIA had previously announced DLSS 4.5 Ray Reconstruction for release this month, but no games had yet utilized it—until now.
A Surprise Addition to the Beta
What makes this discovery particularly noteworthy is that the Ray Reconstruction model came bundled with a completely new DLSS version, labeled as version 310.7.128. The community has already begun manually replacing DLL files across different games to test the new capabilities.
"This is huge for the PC gaming community," one Reddit user commented. "We're getting early access to tech that hasn't even been officially rolled out yet."
How to Test the New DLSS Version
For enthusiasts eager to try out the new files, third-party tools like Profile Inspector or DLSS Swapper are currently the most reliable methods. Interestingly, replacing files through the NVIDIA app won't work properly—the app fails to detect them all and won't display them as available options.
To test the new DLSS 4.5 Ray Reconstruction:
- Obtain the
nvngx_dlssd.dllfrom version 310.7.128 build files - Back up original files in your chosen game
- Replace the old file with the new one
- Ensure DLSS overrides are disabled in the NVIDIA app
- Change the Ray Reconstruction Preset to Preset F (value 6 in Profile Inspector)
The community has already reported successful testing using this method on Alan Wake 2, Cyberpunk 2077, Crimson Desert, and Hogwarts Legacy. To verify the new model is active, users can utilize NVIDIA's DLSS debug overlay, which comes bundled with DLSSTweaks.
What Makes DLSS 4.5 Special
When NVIDIA announced DLSS 4.5 Ray Reconstruction, they highlighted significant improvements over previous versions. The new model uses a second-generation transformer architecture featuring:
- 20% more parameters than its predecessor
- 35% more compute capability
- Maintained performance similar to previous models
- Improved temporal stability
- Better lighting accuracy
- Enhanced detail preservation during motion
Early community testing confirms these promises, with users reporting reduced ghosting, less temporal flickering, and noticeably better detailing. Results vary depending on the game and specific graphics settings, but the overall reception has been positive.
Official Release on the Horizon
With August drawing to a close, industry analysts expect the official DLSS version and DLSS 4.5 Ray Reconstruction model to launch within the next week. All signs point to Gamescom as the likely venue for the official announcement, where many gaming companies are scheduled to make major reveals.
"This is just the beginning," one industry insider noted. "Once DLSS 4.5 becomes widely available, we'll likely see a wave of games implementing it."
