Rendering

OpenGL

{
    "FFlagDebugGraphicsDisableDirect3D11": true,
    "FFlagDebugGraphicsPreferOpenGL": true
}

Vulkan

Warning

May cause bugs, issues and instability.

{
    "FFlagDebugGraphicsDisableDirect3D11": true,
    "FFlagDebugGraphicsPreferVulkan": true
}

Lighting

Enable GPU Light Culling

Note

Light culling is a technique in computer graphics used to optimize rendering by determining which lights affect which objects in a scene, reducing unnecessary lighting calculations and improving performance.

{
    "FFlagFastGPULightCulling3": true
}

Enable CPU Light Culling

{
    "FFlagDebugForceFSMCPULightCulling": true
}

Graphical

Occlusion Culling

Only renders instances that is visible to the player. Improves FPS significantly on lower-end devices.
