REQUIRES DX11
RenoDX rewrites the game's shaders to fix and enhance its HDR implementation. It improves tonemapping, brightness control, and color grading for a more immersive experience. RenoDX uses the Reshade Add-on API, not Reshade effects.
Features
General:
- Based on ReShade's Addon system, eliminating the need for patches after game updates.
- 3 customizable presets.
- "Off" Preset that roughly matches how the game looks without the mod.
- New tonemapper built on the Daniele Curve, the basis for ACES 2.0.
- Realtime sliders for instant feedback.
- In-game HDR sliders have been disabled and replaced with RenoDX's own sliders in the RenoDX menu
- Gamma Correction Fix: The original SDR used sRGB gamma but was likely still made on 2.2 gamma displays. The HDR implementation mistakenly does not correct for this mismatch, resulting in grayish, washed-out shadows. The game's developers added a contrast slider as an attempt to remedy this issue, but it provided poor results. This issue has been properly addressed by correcting for gamma mismatch so the output resembles 2.2 gamma, eliminating the need for a contrast slider fix.
- Better brightness control: The game defaulted to a high brightness level and the lowest value of 80 is still fairly bright for a dark room. RenoDX allows for a greater range of brightness adjustment.
- Fixed Highlight Clipping: The game's brightness slider scales brightness after tonemapping, but the vanilla tonemapper's peak nits didn't properly adjust for when the user adjusted the brightness slider, so the developers just clipped highlights to cover up overshoot.
- Peak Brightness: Adjust the game's maximum brightness to fit your display.
- Game Brightness: Control the brightness of the game render.
- UI Brightness: Control the brightness of UI elements.
