Drops OptiScaler v0.9.1 + a FH5-tuned OptiScaler.ini into the FH5
install dir to unlock FSR 4 INT8 on this RDNA 3 (Navi 32) box.
OptiScaler intercepts FH5's DLSS/XeSS calls and reroutes them through
the bundled FFX SDK. Per the OptiScaler FH5 wiki page: rename
OptiScaler.dll to dxgi.dll, set Dxgi=false, DlssReactiveMaskBias=0.65,
and Fsr4Update=true for the INT8 RDNA 3 path.
Sets Steam launch options PROTON_FSR4_UPGRADE=1 and
DXIL_SPIRV_CONFIG=wmma_rdna3_workaround on fh5-optiscaler (the FSR 4
wiki documents both as required for RDNA 3 on Linux).
fh5-vkd3d-no-hvv is its own mod (no files, just one launchOptions
entry for VKD3D_CONFIG=no_upload_hvv) so the upload-hvv workaround
can be removed when a future Proton release fixes the underlying
issue without disturbing the OptiScaler config.
Extends the intro skip stub to cover the hires variant of the
T10/Microsoft Studios splash; the engine picks SD or hires based on
the installed asset profile, so stub both per PCGamingWiki.
