  • Disable motion blur in the post processing settings
  • The in-game anti-aliasing option needs to be enabled for TAA to work as intended.
  • If you plan to use the HDR Bloom effect of this mod, it is recommended to turn bloom and light shafts off in the post processing settings
  • If sparks and igni are too red for your taste, try out the optional file "Blitz Igni"


  • Press F8 to open the BlitzFX settings
  • For more informations on the settings see the "BlitzFX Documentation" in bin\x64\blitz_resources.


  • Compatible with lighting mods

  • Depending on your setup and resolution, your FPS will drop by about 5 to 15 frames with all effects enabled.
