# Launches a Windows game through a GE-Proton build's integrated OptiScaler
|
||||
# (PROTON_USE_OPTISCALER) with OptiScaler's DLSS backend routed into the d4r
|
||||
# shim, i.e. official NVIDIA DLSS executed through the Wine CUDA bridge and
|
||||
# ZLUDA on the AMD GPU.
|
||||
#
|

# usage: run_game_d4r_optiscaler_proton.sh PROTON_DIR COMPAT_DATA_DIR GAME_EXE [ARGS...]
|
||||
#
|
||||
# The Proton installation and game directory are not modified. The prefix's
|
||||
# system32/umu/OptiScaler.ini (rewritten by GE-Proton from
|
||||
# PROTON_OPTISCALER_CONFIG) is restored when the game exits, and the real
|
||||
# DXVK-NVAPI is placed next to the identity bridge as d4r_nvapi64_real.dll.
|
||||
# With D4R_VKD3D_DIR (a directory holding d3d12.dll and d3d12core.dll, e.g. the
|
||||
# d4r-patched vkd3d-proton), those replace Proton's vkd3d-proton in the prefix
|
||||
# for this launch; the prefix's previous copies are backed up to the log
|
||||
# directory and restored when the game exits.
|
||||
# With D4R_UE_ENGINE_INI (the game's Saved/Config/Windows/Engine.ini) and
|
||||
# D4R_UE_CVARS ("r.A=0;r.B=1"), those console variables are added to its
|
||||
# [SystemSettings] for this launch only: an existing file is backed up to the
|
||||
# log directory and restored on exit, a new one is removed again. Unreal games
|
||||
# apply tonemapper sharpening and chromatic fringe after the upscaler; e.g.
|
||||
# Townfall's r.Tonemapper.Sharpen and r.SceneColorFringeQuality turn DLSS's
|
||||
# clean thin lines into haloed, stippled and beaded ones.
|
||||
# Logs go to D4R_GAME_LOG_DIR (default: a timestamped capture directory).
