Persona 4 Arena Ultimax [DX11]

Helix Mod [Unofficial] May 3, 2026

geo-11 fix for Persona 4 Arena Ultimax. The game originally runs in DX9, so this needs dgVoodoo to convert the game to DX11.

Fixed

  • Character sprites, other effects and HUD are at correct depth too.
  • Clouds in a puddle reflection put to full depth.
  • Haloing issues.

Known issues

  • The main menu looks pretty bad, but for now I didn't see a way to disable 3D in it without harming gameplay. Just in case, I don't want to risk it. But you can still easily see all the options in the menu.

Installation

  • Before installing anything, make sure the game is running in windowed mode at 1920x1080 and also without MSAA. Fullscreen and MSAA (not necessarily together) break graphics completely.

  • geo-11 (with build v0.6.164): download this file and extract its contents in the "P4U2 " folder, where "P4U2.exe " is. Remember to edit "d3dxdm.ini " to change your "direct_mode" to the output you need. It's set to "sbs" by default and also "upscaling" is set to 1 in that same file.

  • Install dgVoodoo (v2.87.1 is the version that you need. Different ones may break effects) by copying the "MS\x86\D3D9.dll " file to the folder where you installed the fix. Then run "dgVoodooCpl.exe " to configure dgVoodoo similar to this:

Setting "Mipmapping to "Auto-gen with bilinear filter" improves the image quality a lot since the game lacks mipmaps.

  • Run the game.

Hotkeys

  • F1 : convergence presets (150, 250, 400). 250 by default.

Notes and reminders

  • Do not attempt to use fullscreen mode. It breaks everything due to some incompatibility with dgVoodoo. Also, borderless mode leaves the game as a small rectangle in the middle when you try to upscale to 4K, so it's best to use windowed mode.
  • Also remember to disable MSAA ingame.
  • Upscaling is already enabled in the fix, with "upscaling = 1" in "d3dxdm.ini". If you want to disable that, set it to 0.
