The Call of Duty: Modern Warfare 4 beta is currently ongoing for pre-order customers, and eagle-eyed observers have noticed that the game files bundle in the heretofore unreleased second-gen version of Nvidia's DLSS ray reconstruction tech.

DLSS 4.5 adds a new "F" model for ray reconstruction, and it's possible to swipe the .DLL file from the beta and copy it into other game directories to automagically upgrade to the new DLSS ray reconstruction model.

Tools like DLSS Swapper also exist to automate this process, and while this particular tool doesn't support Model F yet, you can tweak the program slightly to enable it early. In short, you'll just need to check the DLSS Swapper install directory, open a file with Notepad using admin privileges, then duplicate the "Preset E" entry, changing it to Preset F with the hex value of six. The instructions are available via the DLSS Swapper tweet below.

If you're not that fussed to try the new model early, it should be announced properly at a Nvidia event at Gamescom in Cologne tomorrow, August 25th, and presumably rolled out via the Nvidia app soon thereafter.

The "GeForce On Community Update" stream kicks off at 5PM local time (so 4PM UK), and should include the usual assortment of game showcases and feature updates for various gaming products, including DLSS.

Are you hoping for anything in particular from the GeForce stream? Are you going to tune in, given the busy Gamescom schedule? Let me know in the comments below.
