# PS5 DualSense adaptive triggers in Forza Horizon 4 / 5.

# Declarative game-file mods on top of Steam (file drops only; Steam launch
# options live in `programs.steam.config.apps` below).
# Steam per-app declarative config via steam-config-nix:
# - launch-option env vars (PROTON_FSR4_UPGRADE et al)
# - file drops into the install dir (FH5 intro stubs, OptiScaler DLLs +
# hand-written FH5/RDNA3 INI). Backups land next to replaced files with
# a `.steam-config-nix-backup` suffix on first apply.
#
# fh5-no-intro: stub the 40 MB T10/Microsoft Studios cold-start splash.
# Two copies live in the install (SD + hires); engine picks one based on
# the installed asset profile, so stub both. PCGamingWiki documents both
# paths under "Skip intro video".
# The patcher runs as a system oneshot at activation; closeSteam = true
# ensures Steam is shut down before the localconfig.vdf write so Steam
# can't clobber it on next exit. File drops happen in the same run but
# don't share that concern \u2014 they only touch steamapps/common/<dir>
# and steamapps/compatdata/<id>/pfx.
#
# fh5-optiscaler: drop OptiScaler v0.9.1 + a hand-written FH5/RDNA3 INI into
# the install dir to enable FSR 4 INT8 on this Navi 32 box. OptiScaler
# intercepts FH5's DLSS/XeSS calls and reroutes them through the bundled
# FFX SDK. Override values + sources live in
# ./optiscaler-fh5-rdna3.ini; keys not listed there fall through to
# OptiScaler's "auto" defaults.
# OptiScaler intercepts FH5's DLSS/XeSS calls and reroutes them through
# the bundled FFX SDK. Override values + sources for the FH5/RDNA3 path
# live in ./optiscaler-fh5-rdna3.ini; keys not listed there fall through
# to OptiScaler's "auto" defaults.
#
# Required one-time per-game setup the user has to do in Steam (the
# in-game upscaler picker has no public API):
# - In-game: switch the Upscaling option from FSR 2.2 to DLSS or XeSS
# (FSR 2 inputs aren't intercepted). Press Insert to open the Opti
# overlay and set the FFX upscaler to FSR 4.
# Required one-time per-game setup the user has to do in Steam (no API):
# - Properties > Compatibility: pick the GE-Proton tool by hand. The
# `compatTool` option is intentionally unset \u2014 nixpkgs registers
# proton-ge-bin under its versioned id (e.g. GE-Proton10-34), and
# writing the generic "GE-Proton" string silently falls back to
# bundled Proton.
# - In-game: switch the Upscaling option from FSR 2.2 to DLSS or XeSS
# (FSR 2 inputs aren't intercepted). Press Insert to open the Opti
# overlay and set the FFX upscaler to FSR 4.
#
# Caveats:
# - OptiScaler.ini is dropped with mode = "init" so in-game overlay edits
# persist. The hand-written template is only written on first apply (or
# after manual deletion). To push a new default into an existing
# install: rm OptiScaler.ini in the FH5 dir, then `systemctl start
# game-mods`. The DLLs and other static assets stay mode = "create" so
# they're updated on every OptiScaler version bump.
# - OptiScaler's installation page warns against use with online games.
# FH5 has no kernel-mode anti-cheat but Playground does server-side
# telemetry. Use at your own risk.
