Recently, modder softsoundd returned to Mirror's Edge and used NVIDIA tools to update the game:
This is a custom version of Remix that I've been working on to make Mirror's Edge compatible with NVIDIA RTX Remix. The work is not yet complete, and you may notice some issues, but overall the mod is already in a usable state.
The graphics in Mirror's Edge are transformed thanks to the transition "from pre-calculated lighting to real-time path-traced rendering." softsoundd intends to further improve the project.
The "dxvk-remix-mirrorsedge" mod has already been published in open access on GitHub.
