TheRazerMD edited this page Feb 6, 2026 · 7 revisions

Version

0.9-pre9

Filename

dxgi.dll, OptiScaler.asi

OS

Win 11 24H2

GPU

9070XT

Inputs

DLSS, XeSS, FSR2 (not working)

Settings

Dxgi=false - already applied in 0.9 builds

FG-Settings

  • DLSSG via SL → XeFG - recommended

Known Issues

  • Only recommended if standard dxgi.dll doesn’t work

    • Requires using OptiScaler as OptiScaler.asi with Ultimate ASI Loader, otherwise crashes on launch

    • Download Ultimate ASI Loader x64

    • Rename ASI loader dll (usually dinput8.dll) to winmm.dll, add it to the game folder where OptiScaler is installed as OptiScaler.asi

    • Set LoadAsiPlugins=true in OptiScaler.ini


  • Might also require Fakenvapi (already bundled with 0.9 builds)

  • MS Store/GP version of the game is supported, but Opti Overlay does not work - requires changing settings through OptiScaler.ini - link

  • FSR2 inputs don’t work and should be disabled with EnableFsr2Inputs=false - Opti 0.7.8+ already apply this

Notes

  • Reactive Mask Bias at 0.65 seems to fix the flickering lights and improve car ghosting

  • Car ghosting is unavoidable with FSR-FG - if your GPU is supported (has DP4a), better to use XeFG
