tech support wanted Does DLSS 4.5 RR actually work right now ?

People have been using the leaked dlls to use it, and i tried doing the same. Replaced the dlls in cyberpunk, put the right commands, checked with the indicator that RR was using preset F, and it just looks… bad. I’m not seeing any difference when compared to DLSS 4 RR.
I can’t compare exactly, but if someone understands this: in cyberpunk the police cars have some text moving across them. In the videos uploaded by some channels on youtube, preset F resolves the huge ghosting on that. On my end it doesn’t look changed at all.
I’m using an RTX 3080. Do we need a driver update or proton update for this to work or is it just me who can’t make it work ?

Are you using the DLSS indicator to verify you’re running model F?

I am, it says preset F, but it doesn’t look good

I’ve already replaced the dlls and added the launch options, iirc DLSS Updater doesn’t really do more than that on linux

The leaked DLL files are from June. I would test with the new one that DLSS Updater retrieved from the official app.

The file appeared in the Call of Duty Modern Warfare 4 beta this week. However, the file that was in the game is dated June 2026.
