[BASIC]
; Extension
ENABLED=1 ; Active (set to 0 to disable graphic adjustments); 1 or 0
FORCE_FXAA=1 ; Force FXAA route (enables FXAA in AC video settings without actually applying it to make sure some of the CSP features will work); 1 or 0
__HINT_BOTTOM=Disabling Graphics Adjustments might break most of CSP: a lot of other modules rely on some things set up by this one.

[RENDER_SCALE]
; Render scale
SCALE=1 ; Scale; from 0.1 to 1, perc.
SCREENSHOTS_SCALE=1 ; Accumulative screenshots (keep at 100% to create full-resolution screenshots); from 0.1 to 2, perc
__HINT_BOTTOM=This option affects render, UI and everything else, good for fixing the size of original UI elements and improving performance on high DPI screens. For example, if you’re using a laptop with a 4K monitor, set AC resolution in video settings to maximum, disable fullscreen mode, set this scale to 50% and you’ll get a FullHD experience and a massive performance boost.<br><br>Not compatible with fullscreen mode. Also, screenshot scale might not be available with some older advanced WeatherFX styles.

; AMD FidelityFX Super Resolution
ACTIVE=0 ; Active; 1 or 0; not available with IS_LIVE__
DISABLE_FOR_SCREENSHOTS=1 ; Disable for screenshots; 1 or 0

QUALITY2=0.77 ; Quality, new (resolution multiplier is in brackets); "Custom (Any%)" is -1, "Best Quality (87%)" is 0.87, "Ultra Quality (77%)" is 0.77, "Quality (67%)" is 0.67, "Balanced (59%)" is 0.59, "Performance (50%)" is 0.5, "Sad (25%, for testing)" is 0.25; hidden with OLD_IMPLEMENTATION; not available with IS_LIVE__
CUSTOM_PIXEL_DENSITY=1.2 ; Pixel density; from 0.1 to 2, perc.; visible with OLD_IMPLEMENTATION=1 and QUALITY=-1 or OLD_IMPLEMENTATION=0 and QUALITY2=-1
SHARPEN=-1 ; Sharpness, old; Auto is -1, Very low is 0.15, Low is 0.3, Medium is 0.5, High is 0.7, Very high is 0.85; visible with OLD_IMPLEMENTATION
SHARPEN2=0.5 ; Sharpness, new; from 0 to 1, perc.; hidden with OLD_IMPLEMENTATION
ADJUST_MIP_BIAS=0.5 ; Adjust MIP bias; from 0 to 1, perc.; hidden with OLD_IMPLEMENTATION

__HINT_BOTTOM=Available only with single or triple with both post-processing and FXAA in AC video settings active, or in VR (any combination of settings). Might negatively affect screenshots quality. Works with AMD Radeon, Intel UHD and NVIDIA GPUs. Restart Assetto Corsa to activate, deactivate or change quality preset, other settings can be changed live.

[LODS]
; LOD settings

TREAT_TRACK_CAMERAS_THE_SAME=1 ; Treat track cameras the same; 1 or 0

__HINT_BOTTOM=Please note: the way this and a few other effects work, they’re intercepting FXAA when Assetto Corsa applies it. So, keep FXAA enabled in original video settings. If you don’t need it, instead, disable it here.

; Tweaks
DISABLE_LDR_FIX=1 ; Disable HDR-LDR conversion for AC emissives (a lot of CSP features might break if this tweak is disabled); 1 or 0; hidden
BLOCK_COLOR_CLEAR=1 ; Skip color clearing stage (might slightly improve performance, but mainly, might help to hide small holes in some track models); 1 or 0
USE_VIRTUAL_MIRROR_MASKING=0 ; Do not draw anything under virtual mirror (for single or triple mode and only if it’s drawn with post-processing active, might improve performance a bit); 1 or 0; only with BLOCK_COLOR_CLEAR
