Key points
- Complete suite of game development tools and engine used by over 1000 games, see Games.
Video
Multi-monitor
See Ultra-widescreen.
Ultra-widescreen
- Unreal Engine games are Vert- by default, unless the developer specifically implements proper Hor+ ultrawide support. See each individual game's entry page for specifics.
- If a game is Vert-, FOV can be increased to give a proper 1:1 Hor+ ultrawide image. See the ultra-widescreen glossary page for details.
- If a game does not allow FOV to be adjusted, and an external mod to implement it does not exist for the specific game in question, then the game does not support a proper ultrawide experience.
- For multi-monitor or 32:9 setups, the resolution may be so wide that the in-game FOV option may not go high enough to achieve a proper 1:1 Hor+ image. See individual game entry pages for workarounds.
Field of view (FOV)
- The FOV variable name is set individually by each developer and differs from game to game, so unfortunately there is no universal solution for adjusting FOV in games where it is not available as an option.
- If the developers of a particular game have implemented FOV as a variable, it can usually be adjusted in
GameUserSettings.ini
. - For games in which customizable FOV is not supported, a wider FOV can be obtained by changing the FOV scaling from horizontal to vertical.

High dynamic range (HDR)
For a list of known games and their specifics, see Unreal Engine 4-5 games where HDR can be forced.
Unreal Engine 4 has had native HDR output support since version 4.14 and it can be forced in many games that don't officially support it with mixed results.
Earlier versions of the engine required running in Exclusive Fullscreen (FSE) in order for this to work, while newer versions supports it for windowed modes as well, though some more recent versions have broken HDR in DirectX 12 out of the box,[citation needed] requiring the use of -dx11
launch argument to run games in DirectX 11[Note 1].
Depending on the version of the engine or the way it renders UI, the UI might use the wrong gamma and look washed out. Additionally, some color correction features of the SDR tonemapper are skipped in HDR, like parts of the filmic grading (which isn't necessary, nor generally wanted in HDR) and color correction LUTs.
Some games don't acknowledge user config changes, for these it's sometimes possible to force HDR by runtime memory editing.
Force the built-in HDR display output of the engine: |
---|
Engine.ini or GameUserSettings.ini to include the following lines or enforce the variables via UE4SS:
[SystemSettings] r.AllowHDR=1 r.HDR.EnableHDROutput=1 r.HDR.Display.OutputDevice=5 r.HDR.Display.ColorGamut=2 Recommended changes (optional): r.HDR.UI.CompositeMode=1 r.HDR.UI.Level=1.5 Notes

Issues fixed
Stuttering
- There are two main causes of stutters in Unreal Engine 4 games, shader compilation stutters as well as texture streaming related stutters.
Shader compilation related stuttering |
---|
Unfortunately there is no console variable (cvar) to tweak this behavior,[citation needed] however DXVK-async might be used to reduce or eliminate shader compilation stutters since it offloads these operations to a worker thread instead of performing them on the main rendering thread of the game. Note however that using DXVK-async may reduce the average frame rate by up to 20% depending on the game. |
Forcibly enable compiling of shaders on load |
---|
[/script/engine.renderersettings] r.CreateShadersOnLoad=1 niagara.CreateShadersOnLoad=1
|
Texture streaming related stuttering |
---|
Using the guide below, modify [SystemSettings] r.TextureStreaming=0 |
Disable Control Flow Guard |
---|
|
Jittery temporal anti-aliasing
- At higher TAA sample counts edges may appear jittery, even when still with no camera movement.
- Fortunately it seems there's a way to remove the jitter without compromising on TAA quality/sample count.
- This method may cause more ghosting to appear in some games.
Stop current frame from being considered in TAA |
---|
Using the guide below, modify [SystemSettings] r.TemporalAACurrentFrameWeight=0 Note that as mentioned above this may cause more ghosting artifacts to appear, likely depends on which UE4 version the game uses as different UE4 versions use slightly different TAA implementations. Using a value range of =0.2 through =.45 will remove ghosting and jitter. Value range is dependent on the game. Start at .2 then increase as needed. |
- This bug may occur when using a Vulkan beta driver from Nvidia.
Disable Use Collapsed Arrays option for the game |
---|
Run the game with this Launch Parameter: __GL_GlslUseCollapsedArrays=0 On Steam that would be: __GL_GlslUseCollapsedArrays=0 %command% |
Native resolution is not available in borderless window modes
- Newer versions of Unreal Engine 4 handles DPI automatically and prevents the use of native resolutions when a borderless window mode is being used. The render resolution will instead be the lower "DPI-aware" resolution.
- For example, on a 3840x2160 monitor with 150% DPI scaling set, 2560x1440 will be used instead, as 3840 / 1.5 (150%) = 2560 and 2160 / 1.5 (150%) = 1440.
Allow a game to use the native resolution in borderless window modes[7] |
---|
|
SteamVR starts despite the game not using HMD devices
Start the game with -nohmd parameter.[8][9]
|
---|
Other information
GameThread timed out waiting for RenderThread - After Windows Standby
- Games may crash after a longer standby period. This can be fixed by increasing the timeout value.
Increase the timeout value |
---|
Using the guide below, modify [SystemSettings] g.TimeoutForBlockOnRenderFence=9999999 |
Unreal Engine 4/5 Scripting System
- UE4SS is a scripting system for UE4/UE5. Includes a console enabler script by default.
- While UE4SS has a high compatibility with most UE titles, only UE 4.12 onwards are officially supported by it, and certain games may also have customized the engine enough for UE4SS to no longer be compatible. Titles not supported by UE4SS may have support added by the UE4SS community, searching the GitHub Issues page may help to find UE4SS configs for unsupported games.

Enable developer console
- The developer console allows real-time adjustments through various Unreal Engine 4 console variables, along with being able to run debug commands like ToggleDebugCamera that enables a flycam mode. Most games ship with the console disabled, although often retains code related to it that allows for its reactivation through third-party DLL injection.
- Independent of custom game code - potential for reliability.

Permanent console variable (cvar) changes
- Global list of all console variables available here.
- Like most engines that use console variables, Unreal Engine 4 has a config file that the variables' values are read from at startup.
- Unlike in most engines, the method it uses may not be obvious. Editing files such as
Scalability.ini
could result in entered values being ignored depending on the graphics settings.
Add cvar name/values to Engine.ini
