Sims 4: Best GraphicRules.sgr for 2026 Hardware Recognition

The objective is to manually add your GPU’s Device ID to the game’s database and override the texture memory limits that often cause “blurry textures” on 12GB+ VRAM cards.

1. Finding Your GPU’s Device ID

Before editing, you need to know exactly how the game sees your hardware.

File Path: Documents\Electronic Arts\The Sims 4\Config.log

Open this file and look for the Graphics Device Info section. Note down these two values:

• Vendor: (e.g., 10de for NVIDIA)
• Device: (e.g., 28a0 for an RTX 4060 or a newer 2026 equivalent)

2. Editing GraphicsCards.sgr

This file tells the game what your card is. To prevent game updates from overwriting your changes, use the ConfigOverride folder.

Step-by-Step:

1. Go to C:\Program Files\EA Games\The Sims 4\Game\Bin.
2. Copy GraphicsCards.sgr.
3. Paste it into Documents\Electronic Arts\The Sims 4\ConfigOverride.
4. Open the copy and search for your Vendor (e.g., NVIDIA).
5. Add a new line under the vendor section:card 0x[YourDeviceID] "Your GPU Name" $cardLevelUber $resolutionHigh

3. Editing GraphicRules.sgr (The “Uber” Override)

While GraphicsCards identifies the hardware, GraphicRules.sgr determines the performance caps.

Variable to Search	Recommended 2026 Value	Technical Purpose
seti textureMemory	4096 or 8192	Forces the game to utilize more VRAM for high-res CC/Mods.
prop $ConfigGroup ShadowMapSize	4096	Increases shadow resolution to 4K (Ultra is usually 2048).
prop $ConfigGroup SsaoEnabled	true	Ensures Ambient Occlusion is active on modern GPUs.
seti cpuLevel	4	Forces the engine to use the highest level of simulation logic.

4. Performance Tip: The 2026 “Memory Boost”

A new feature introduced in recent patches is Memory Boost (FPB).

• The Check: Open the cheat console (Ctrl+Shift+C) and type version. If you see (FPB) in the summary, the game is utilizing its 2026 memory optimization patch.
• If missing: Ensure your GraphicRules.sgr has seti useMemoryBoost true added under the [Config] header to allow the game to exceed the legacy 4GB RAM limit more effectively.
