Key points

A controller is recommended.
Features 60 FPS support, albeit slightly botched with some lagspikes and harder QTEs. The game speed is bound to frame rate and has no frame skipping, some animations play at lower frame rate.
Some improved textures over previous versions. An unofficial texture project is also being developed to completely revise them.
Mouse controls are hit-or-miss. While they work fine for some, others experience issues such as unresponsiveness, possibly to the extent of being unplayable.[1][2][3] See mouse aiming problems for potential fixes.
Positional audio is hit-or-miss; many sound effects are mono.[citation needed]

Essential improvements[edit]

Ambient occlusion mod[edit]

This is a mod which adds AO. You have to disable AA to get it to work, but you can add SMAA in with ReShade. It doesn't work with cutscenes.
Please note that AO can be very taxing on the framerate, and you may have to choose between AO and 60 FPS. If you choose AO due to the framerate hit, then change it to 30 FPS in the game's settings.
For more information, see this.

To install, extract this to the game's Bin32 folder.

Open d3d9.ini with notepad, and change the four paths to where RE4 is located. Chances are, it should be:

EffectSearchPaths=C:\Program Files (x86)\Steam\steamapps\common\Resident Evil 4\Bin32\reshade-shaders\Shaders
TextureSearchPaths=C:\Program Files (x86)\Steam\steamapps\common\Resident Evil 4\Bin32\reshade-shaders\Textures
PresetFiles=C:\Program Files (x86)\Steam\steamapps\common\Resident Evil 4\Bin32\AO.ini
ScreenshotPath=C:\Program Files (x86)\Steam\steamapps\common\Resident Evil 4\Bin32

Resident Evil 4 HD Project[edit]

Resident Evil 4 HD Project is a mod aiming to revise the textures of the game. It intends to be very faithful to the original look, as the creators even went to the real-life European locations to capture photos of the art and architecture. It also re-does effects such as lighting so that they make more logical sense, while fixing some of the environmental problems leftover in the game
Current version was released July 13, 2018, which basically covers the vast majority of the environments. A trailer with comparisons is here. These are still yet to come: Characters, enemies, background files, and some effects (blood, fire) and lighting retouchments. There is no release date for the next version.
How to install HD Project[4]
  1. Download the HD Project here. Follow the instructions.


Windows 10 users may encounter problems installing the HD Project using the provided .bat file. Follow these instruction if you are having problems installing the HD Project.

  4. Now type install-hd-texture-packs.bat and press Enter to run the .bat file and install the new textures.

Natural Gradient Mod[edit]

Film Grain Removal Mod[edit]

120+ FPS
Frame rate must be capped at either 30 FPS or 60 FPS. Editing higher value in config file results in the game running in slow motion.[8]

Field of view (FOV)[edit]

Even though Flawless Widescreen claims it supports Resident Evil 4, it does not work past patch 1.0.2; a modified plugin is required to support later versions.
Unofficial Flawless Widescreen FOV patch by λ[9]
  1. Install and open Flawless Widescreen.
  2. Install the Resident Evil 4 plugin and close the program.
  3. Go to the Flawless Widescreen installation folder.
  4. Go into the \PluginCache\FWS_Plugins\Modules\ResidentEvil4\Dependencies\Scripts\ folder.
  5. Download the modified ResidentEvil4.lua.
  6. Copy the modified ResidentEvil4.lua to Scripts\ and replace the existing file.
  7. Open Flawless Widescreen and adjust the FOV as needed.

NOTE: This method below is meant for 1.0.6, not 1.1.0. It will probably not work on 1.1.0, while the above method likely will.

Change FOV with Cheat Engine[10]
  1. Download and install Cheat Engine, but be warned during installation: Cheat Engine is one of those types of programs where if you just install it blindly, you'll also install other unnecessary programs, so be sure to deselect checkboxes.
  2. Download the cheat table.
  3. Open the cheat table to load it in Cheat Engine.
  4. Start the game and Alt+Tab out.
  5. In Cheat Engine, click the flashing button in the top left corner.
  6. Select bio4.exe and click Open, then click Yes.
  7. At the bottom part of Cheat Engine, check the boxes on the left beside the character to show the values below.
  8. Check the boxes beside the camera views you wish to modify to freeze the values (e.g. FOV, Gun, Knife, etc.)
  9. Select one or more of them, then press Enter and type in a new FOV value.

Anisotropic filtering (AF)[edit]

Change sample rate[citation needed]
  1. Go to the configuration file(s) location.
  2. Open config.ini.
  3. Change anisotropy 16 to the desired value.

Vertical sync (Vsync)[edit]

DualShock Button Prompts[edit]

Mute on focus lost[edit]

Set mute in background[citation needed]
  1. Install Special K by following the Special K Unofficial Guide. Manual local installation may work better.
  2. Start the game once and close it to allow the configuration file of Special K to be created.
  3. Open <path-to-game>\Bin32\d3d9.ini or %USERPROFILE%\Documents\My Mods\SpecialK\Profiles\bio4.exe\SpecialK.ini depending on the installation method you used.
  4. Change MuteInBackground=false to MuteInBackground=true under [Window.System].

VR support[edit]

Issues fixed[edit]

Random slow downs[edit]

If you're playing the game and it suddenly slows down, load the map and exit.[citation needed]

Mouse aiming problems[edit]

Some players have reported problems using the mouse to aim their weapon.[citation needed] This can potentially be improved by changing the aim mode to "Modern" and adjusting the sensitivity level.

Can't pass QTE[edit]

In some QTEs, such as when Leon is hanging on a ledge in Chapter 4, mashing the buttons as fast as you can might still not pass the QTE. This is because of botched 60 FPS support, requiring QTEs to be mashed faster.[citation needed] Try changing it to 30FPS, or use Cheat Engine, attach the process, Speed Hack it to 0.5, thus giving you more time to press the button. After the QTE, simply exit Cheat Engine and continue the game. Another tip is to mash the button even before the prompt appears.


Stop "Touch Keyboard and Handwriting Panel Service" Windows service[citation needed]
Crashes around after 15 minutes of gameplay in Windows 8 and 10.
  1. Open Task Manager.
  2. Go to Services.
  3. Identify "Touch Keyboard and Handwriting Panel Service" (TabletInputService).
  4. Stop the service.
  5. Launch RE4.
Disable Bitdefender antivirus[12]
Known affected areas are chapters' 1-3 "swamp area" and 3-1 "castle water room".

Run the game at screen refresh rate[edit]

Fullscreen mode defaults to 60 Hz, even if the screen refresh rate is set higher than that.
Set screen refresh rate[citation needed]
  1. Install Special K by following the Special K Unofficial Guide. Manual local installation may work better.
  2. Start the game once and close it to allow the configuration file of Special K to be created.
  3. Open <path-to-game>\Bin32\d3d9.ini or %USERPROFILE%\Documents\My Mods\SpecialK\Profiles\bio4.exe\SpecialK.ini depending on the installation method you used.
  4. Change RefreshRate=-1 to RefreshRate=0 under [Render.FrameRate].
