FULLNAME=DXGI
DESCRIPTION=Various tweaks and options for DirectX Graphics Infrastructure (DXGI).
SHORT_DESCRIPTION=Tweaks for DXGI

[COMMON]
; Common tweaks
; (independent section)
DPI_AWARE=1 ; DPI aware (forces AC window to be the exact resolution set in video settings despite monitor DPI setting); 1 or 0
TRIPLE_BUFFERING=0 ; Use triple buffering (might help to prevent screen tearing if vertical synchonization is disabled); 1 or 0
MAXIMUM_LATENCY=0 ; Maximum latency (the number of frames that the system is allowed to queue for rendering, use 0 for driver-defined default, which is usually 3 frames. Lower values might reduce input lag and increase responsiveness, while higher values might help to achieve smoother FPS); from 0 frame(s) to 8, round to 1
SELECT_ADAPTER=0 ; Select GPU based on selected screen (if you have two monitors connected to two different GPUs — like dedicated and integrated, for example — and specify AC to appear on a certain screen, this option would make it choose GPU according to the screen you selected, allowing to use fullscreen mode on a secondary GPU and moving rendering job to it); 1 or 0
TRUE_BORDERLESS=0 ; Window style (true borderless mode actually disables window border no matter the window size); 0 for Default, 1 for True borderless, 2 for With border
CENTER_WINDOWED=1 ; Center windowed window (center windowed window in the middle of its screen if resolution is lower); 1 or 0
BACKGROUND_PAUSE=0 ; Idle in background (lowers FPS when AC is in background to save battery and lower CPU and GPU consumption); 0 for Disabled, 2 for 30 FPS, 1 for 2 FPS
BACKGROUND_COLOR='#000000' ;; hidden
HIDDEN_LOADING=0 ;; hidden
ACCELERATED_EXIT=1 ; Instantly close AC window when exiting (replays and such will be saved in background); 1 or 0
SAVE_WINDOW=0 ; Save window position and size (if resized, changes resolution in AC video settings. Does not work if AC is running in fullscreen mode.); 1 or 0; new

[BASIC]
; New DXGI flip model
ENABLED=0 ; Active (set to 0 to disable DXGI & HDR tweaks); 1 or 0
ALLOW_TEARING=0 ; Allow tearing for lower latency; 1 or 0
__HINT_BOTTOM=DXGI flip model allows to draw directly to Desktop Window Manager buffer, speeding up windowed mode (doesn’t work in fullscreen). Requires Windows 10 to work. <url="https://docs.microsoft.com/en-us/windows/win32/direct3ddxgi/dxgi-flip-model">More information</url>.

[HDR]
; HDR support (for HDR screens only)
ENABLED=0 ; Active; 1 or 0; only with BASIC/ENABLED
UI_GAMMA=0.45 ; UI gamma; from 0.1 to 2, perc.
UI_BRIGHTNESS=1.7 ; UI brightness; from 0 to 4, perc.
__HINT_BOTTOM=Make sure to activate DXGI flip model and run AC in non-fullscreen mode for this option.

[HDR_YEBIS]
; HDR support with YEBIS
USE_FILTER_VALUES=1 ; Use PP-filter HDR-related values if defined; 1 or 0; only with HDR/ENABLED
FORCE_LINEAR_FUNCTION=1 ; Force linear function for YEBIS; 1 or 0; only with HDR/ENABLED
BRIGHTNESS_ADJUSTMENT=0.2 ; YEBIS brightness; from 0 to 1, perc.; only with HDR/ENABLED
POST_TONEMAPPING=1 ; Final tonemapping; 1 or 0; only with HDR/ENABLED
POST_GAMMA=0.45 ; Final gamma adjustment; from 0.1 to 2, perc.; only with HDR/ENABLED
POST_BRIGHTNESS=1.2 ; Final brightness; from 0 to 4, perc.; only with HDR/ENABLED
__HINT_BOTTOM=Although YEBIS (AC post processing framework) can process data without accuracy loss, it still clamps brightness. However, HDR displays are still limited and require tonemapping, so it’s actually useful as long as brightness is lowered before sending image to YEBIS, and raised afterwards.<br><br>Of course, it would require PP-filter settings, especially tonemapping-related, to be adjusted. With final tonemapping option enabled here, it might be better to switch YEBIS tonemapping to linear mode.

; [HDR_DIRECT]
; ; HDR support without YEBIS
; SCENE_BRIGHTNESS=1.0 ; Scene brightness; from 0 to 1, perc.
; SCENE_GAMMA=0.45 ; Scene gamma adjustment; from 0 to 1, perc.
; __HINT_BOTTOM=
