The GraphicsRules.sgr file in The Sims 4 is a configuration script that controls how the game detects and applies graphics settings based on your hardware. It is essentially a set of rules written in a scripting language that the game uses to determine:

WHAT IT DOES

Graphics Card Detection
  • It checks your GPU (Graphics Processing Unit) and assigns it a category like low, medium, high, or ultra.
  • If your GPU isn’t recognized, the game might default to low settings.

Automatic Settings
  • Determines the default resolution and quality settings (shadows, lighting, texture detail, etc.) for your system.
  • Helps the game decide what settings to apply when you click “Reset to Defaults.”

Feature Enable/Disable
  • Controls features like edge smoothing (anti-aliasing), post-processing, lighting effects, and bloom based on hardware capability.
  • Can disable certain high-end effects on weak GPUs.

GPU Blacklist or Exceptions
  • Contains rules to blacklist unstable GPUs or set exceptions for integrated graphics.
  • Prevents crashes by disabling unsupported options.

Why It Matters
If your graphics card is misidentified (e.g., listed as "Unknown" in Config.log), the game might force low settings even if you have a powerful GPU.

Advanced players sometimes edit this file to:
  • Force higher settings than the game allows.
  • Enable unsupported resolutions.
  • Improve performance by turning off effects manually.

Caution: Editing GraphicsRules.sgr incorrectly can cause crashes or weird graphics issues. Always make a backup before modifying it.
