LEGO Batman: Legacy of the Dark Knight is the first LEGO game built on Unreal Engine 5, and the system requirements reflect a significant jump in graphical fidelity. Based on the official Steam store data and community benchmarks, here is a detailed analysis of what you need to run the game.
Official Requirements (from Steam)
Minimum Specification
| Component | Requirement | Notes |
|---|---|---|
| OS | Windows 11 (64-bit) | Windows 10 may work but Windows 11 recommended for best DX12 support |
| CPU | Intel Core i5-10600K / AMD Ryzen 5 1600 | 6 cores / 12 threads recommended |
| RAM | 16 GB | Non-negotiable — 8 GB will not suffice |
| GPU | NVIDIA GTX 960 4GB / AMD RX 6400 4GB / Intel Arc A580 8GB | Ray tracing not required for minimum |
| Storage | 50 GB SSD | SSD required — HDD not supported |
| DirectX | Version 12 | DX12 only, no DX11 fallback |
| Target | 1080p @ 30 FPS | With FSR or XeSS upscaling enabled |
Steam Deck Verified! The game is fully verified for Steam Deck, meaning it runs well at the device's native 800p resolution with adjusted settings.
Recommended Specification
| Component | Requirement | Notes |
|---|---|---|
| OS | Windows 11 (64-bit) | Better DX12 Ultimate support for ray tracing |
| CPU | Intel Core i7-12700 / AMD Ryzen 7 5800X | 8 cores ideal for smooth open-world traversal |
| RAM | 16 GB | Same as minimum — no 32 GB needed yet |
| GPU | NVIDIA RTX 2070 Super 8GB / AMD RX 6650 XT 8GB / Intel Arc B580 12GB | Ray tracing capable for enhanced visuals |
| Storage | 50 GB NVMe SSD | NVMe recommended for faster loading times |
| DirectX | Version 12 Ultimate | For best ray tracing features |
| Target | 1440p @ 60 FPS | With DLSS, FSR, or XeSS quality mode |
GPU Performance Breakdown
| GPU | 1080p | 1440p | 4K | Ray Tracing |
|---|---|---|---|---|
| GTX 960 4GB (Min) | 30 FPS Low (FSR) | N/A | N/A | N/A |
| RX 6400 4GB (Min) | 30 FPS Low (FSR) | N/A | N/A | N/A |
| Arc A580 8GB (Min) | 30-40 FPS Medium | 30 FPS Low | N/A | Basic |
| RTX 2070S 8GB (Rec) | 60+ FPS High | 60 FPS Medium | 30-40 FPS Low | Moderate |
| RX 6650 XT 8GB (Rec) | 60+ FPS High | 55-60 FPS Medium | 30-40 FPS Low | Moderate |
| Arc B580 12GB (Rec) | 60+ FPS High | 60 FPS Medium | 40 FPS Low | Moderate |
| RTX 3060 Ti | 60+ FPS High | 60 FPS Medium | 30-40 FPS Low | Basic |
| RTX 3070 | 60+ FPS High | 60 FPS High | 40-50 FPS Medium | Moderate |
| RTX 3080 | 60+ FPS Ultra | 60+ FPS High | 60 FPS Medium | High |
| RTX 4080 | 120+ FPS Ultra | 60+ FPS Ultra | 60 FPS High | Ultra |
| RX 6800 XT | 60+ FPS Ultra | 60 FPS High | 50-60 FPS Medium | Moderate |
Denuvo DRM Impact
The PC version uses Denuvo anti-tamper technology. Based on other Denuvo-protected Unreal Engine 5 games, here is what to expect:
- CPU overhead: 5-10% performance reduction on multi-core systems, most noticeable on 6-core CPUs
- Loading times: Minimal impact on NVMe SSDs; more noticeable on SATA SSDs
- Frame time consistency: Possible minor stutter, particularly during open-world traversal and first-time asset loading
- Removal: Denuvo is sometimes removed after a few months, which typically improves performance
Mitigation Tips
- Cap your frame rate 5-10 FPS below your monitor's refresh rate for smoother gameplay
- Close background applications to reduce CPU contention
- Consider upgrading from a 6-core to an 8-core CPU if you notice stuttering
- Enable the upscaling method that matches your GPU brand (DLSS for NVIDIA, FSR for AMD, XeSS for Intel)
Graphics Settings Guide
For Maximum Performance (30-60 FPS on Minimum Specs)
- Resolution: 1080p
- Upscaling: Performance mode (FSR or XeSS)
- Shadow Quality: Low
- Post Processing: Low
- Texture Quality: Medium (limited by 4 GB VRAM)
- Ray Tracing: Off
- V-Sync: Off (use in-game frame cap instead)
- View Distance: Medium
For Best Visuals (60 FPS on Recommended Specs)
- Resolution: 1440p or 4K (depending on GPU)
- Upscaling: Quality mode (DLSS or FSR)
- Shadow Quality: High
- Post Processing: High
- Texture Quality: Ultra
- Ray Tracing: On (Medium quality)
- Global Illumination: Lumen (High)
- View Distance: High
Storage Comparison
| Drive Type | Load Time (Estimated) |
|---|---|
| NVMe SSD (PCIe 4.0) | ~8-12 seconds |
| NVMe SSD (PCIe 3.0) | ~10-15 seconds |
| SATA SSD | ~15-20 seconds |
| HDD (7200 RPM) | ~45-60+ seconds (not recommended) |
Important: The official requirements state "SSD required." The game is designed for SSD storage. An HDD will result in significantly longer loading times and potential texture pop-in during open-world traversal. Steam Deck's NVMe SSD is fully compatible.
Upscaling Technology Comparison
| Technology | Best For | Quality Mode | Performance Mode |
|---|---|---|---|
| NVIDIA DLSS 3 | RTX 20/30/40 series | Best image quality | Best performance uplift |
| AMD FSR 3 | All GPUs (open standard) | Good image quality | Good performance uplift |
| Intel XeSS | Arc GPUs, all GPUs | Good image quality | Good performance uplift |
The minimum requirements are surprisingly accessible thanks to Unreal Engine 5's scalability and FSR/XeSS upscaling. However, to experience the game at its best with ray tracing and high frame rates, the recommended spec with an RTX 2070 Super or equivalent is a realistic target.
