Visual Commands

Commands to customize visual settings and display options

Visual commands allow you to customize how Halo looks and performs, including field of view, resolution fixes, and performance overlays.

Field of View

chimera_fov

Set your field of view. End with “v” to lock to a vertical FoV, or use “auto” for automatic FoV.

degrees · number | string

Field of view in degrees, or “auto” for automatic FoV. Append “v” for vertical FoV (e.g., “90v”)

chimera_fov 90        # Set to 90 degrees horizontal
chimera_fov 90v       # Set to 90 degrees vertical (recommended)
chimera_fov auto      # Automatic FoV

Using vertical FoV helps prevent distortion when switching aspect ratios.

chimera_fov_cinematic

Set FoV specifically for cinematic sequences. Falls back to chimera_fov if not set.

degrees · number | string

Field of view for cinematics

chimera_fov_cinematic 70v

chimera_fov_vehicle

Set FoV specifically for vehicle views. Falls back to chimera_fov if not set.

degrees · number | string

Field of view for vehicles

chimera_fov_vehicle 100v

chimera_lock_fp_model_fov

Prevents the game from scaling first-person weapon model FoV with camera FoV changes.

enabled · boolean

true to lock first-person model FoV, false to allow scaling

chimera_lock_fp_model_fov true

Widescreen & Resolution

chimera_widescreen_fix

Fix scaling of HUD, menu, and text elements for wider aspect ratios.

mode · 0 | 1 | 2 | 3

• 0: Disabled
• 1: HUD fills the screen
• 2: HUD restricted to center 4:3 area
• 3: HUD restricted to center 16:9 area

chimera_widescreen_fix 1  # Fill screen
chimera_widescreen_fix 3  # 16:9 center area (recommended for ultrawide)

This may break some custom maps that have non-standard HUD layouts.

chimera_safe_zones

Sets safe zone sizes for HUD margins. Values are clamped between stock PC values (8, 8) and stock Xbox values (48, 36).

horizontal · number

Horizontal margin (8-48)

vertical · number

Vertical margin (8-36)

chimera_safe_zones 16 12    # Custom margins
chimera_safe_zones off      # Disable

Performance Overlays

chimera_show_fps

Display your current frames per second on screen.

enabled · boolean

true to show FPS, false to hide

chimera_show_fps true

chimera_throttle_fps

Limit Halo’s frame rate to a specific value.

fps · number

Maximum FPS, or 0 to disable throttling

chimera_throttle_fps 144    # Cap at 144 FPS
chimera_throttle_fps 0      # Unlimited

chimera_uncap_cinematic

Remove the 30 FPS cap from cinematic sequences.

enabled · boolean

true to uncap, false to keep 30 FPS limit

chimera_uncap_cinematic true

Graphics Quality

chimera_af 16        # 16x anisotropic filtering (recommended)
chimera_af true      # Enable with default level
chimera_af false     # Disable

enabled · boolean

true to force highest detail, false for normal behavior

chimera_model_detail true

chimera_force_alternate_bump_attenuation

Force alternate bump attenuation method for environmental bump mapping.

enabled · boolean
