FAQ
The game appears dull. Is this even HDR? - By default, RenoDX is configured to match Vanilla SDR. From there you can tweak to your liking. For a more "HDR" appearance, try some of the Color Grading templates.
How is this any better than (insert other HDR process)? - The engine has been rewritten and resources upgraded from 8-bit SDR to 16-bit HDR. The source to create the image is not the SDR image, but the raw image before the game converts it to SDR. This allows information that was completely blown out by the game's original lack of tonemapper to show through. This is not a post-process of an SDR image, but a reprocessing of the native one.
I don't have HDR. Can I use this? - Yes, you can still reconfigure game's visuals with the tonemapper, only you would have to add just Gamma Correction to Off (unless your monitor is in SRGB mode). Peak nits and Game nits should be set to 80 which is Window's default for SDR.
Note: you can find RenoDX mods for more games here.
About RenoDX
RenoDX, short for "Renovation Engine for DirectX Games", is a toolset to mod games. Currently it can replace shaders, inject buffers, add overlays, and write user settings to disks. Because RenoDX uses Reshade's add-on system, compatibility is expected to be pretty wide. Using Reshade simplies all the hook necessary to tap into DirectX without worrying about patching version-specific exe files. The source code is available on GitHub.
