Fallout: New Vegas [DX11]

Helix Mod [Unofficial] June 14, 2026
Source

geo-11 fix for Fallout: New Vegas in DX11 mode, which requires dgVoodoo. To be specific, a very specific non standard version that I already include in the fix (also including the dgVoodoo.conf). That version can be found here, if you're curious.

Fixed

  • Skyboxes.
  • Sun position.
  • Water effects.
  • Specular reflections.
  • Radial blur.
  • Automatic low convergence when bringing up the Pip-Boy.
  • Dynamic HUD depth when gameplay is detected, and screen depth for menus.

Installation

  • geo-11 fix (with build v0.6.164): download this file and extract its contents in the "Fallout New Vegas " folder where "FalloutNV.exe " is. Remember to edit "d3dxdm.ini " to change your "direct_mode" to the output you need (and/or upscaling or the default dm_convergence). It's sbs by default.
  • Run the game through any way you want, like "nvse_loader.exe" or "Fallout_Fullscreen.exe" if you're using the mod that makes it run in borderless mode.

Basic mods I recommend alongside the script extender and other basic patches

  • Fake Fullscreen Mode Windowed - Alt Tab Fix, for easy alt+tab instead of crashing.
  • NVTF - New Vegas Tick Fix, for smooth high fps.

Notes

  • If you open "dgVoodoo.conf" you will see that I set "VRAM" to 4096, which is 4GB of VRAM. Adjust that if you don't have a lot more free VRAM than that.
