Assassin’s Creed Black Flag Resynced PC requirements cover four separate presets, and the gap between the lowest and highest tier is huge. This guide breaks down exactly what CPU, GPU, RAM, and storage you need to run the game at every preset, from a basic 1080p setup all the way to 4K Ultra.
TL;DR
- Minimum needs a GTX 1660 or RX 5500 XT for 1080p at 30 FPS
- Recommended needs an RTX 3060 or RX 6600 XT for 1080p at 60 FPS
- High preset targets 1440p at 60 FPS with an RTX 3080 or RX 6800 XT
- Extreme preset needs an RTX 4090 or RX 7900 XTX for 4K at 60 FPS
- 16GB of dual-channel RAM is required across every single tier
- 65GB of SSD storage is mandatory, the game will not run properly from an HDD
- Supports DLSS 4.5, FSR 4, and XeSS 3 upscaling on PC
Assassin’s Creed Black Flag Resynced Minimum Requirements
The minimum requirements target 1080p resolution at 30 FPS on the Low preset, with Ray Tracing set to Standard and the upscaler set to Balanced. This tier is meant to get the game running, not to make it look great.
- OS: Windows 10 (64-bit) or Windows 11
- CPU: Intel Core i7-8700K @ 3.7 GHz or AMD Ryzen 5 3600 @ 3.6 GHz
- GPU: NVIDIA GeForce GTX 1660 (6GB), AMD Radeon RX 5500 XT (8GB), or Intel Arc A580 (8GB)
- RAM: 16GB dual-channel
- Storage: 65GB SSD (mandatory)
- DirectX: Version 12
Assassin’s Creed Black Flag Resynced Recommended Requirements
The recommended tier targets 1080p at a smoother 60 FPS on the Medium preset, still with Ray Tracing set to Standard and Balanced upscaling.
- OS: Windows 10 (64-bit) or Windows 11
- CPU: Intel Core i5-10600K @ 4.1 GHz or AMD Ryzen 5 3600 @ 3.6 GHz
- GPU: NVIDIA GeForce RTX 3060 (12GB), AMD Radeon RX 6600 XT (8GB), or Intel Arc B580 (12GB)
- RAM: 16GB dual-channel
- Storage: 65GB SSD (mandatory)
Assassin’s Creed Black Flag Resynced High Preset (1440p)
If you want 1440p at 60 FPS on the High preset with Quality upscaling, the requirements jump up significantly. This is likely to be the sweet spot for players who want a noticeably better visual experience without chasing 4K.
- CPU: Intel Core i5-11600K or AMD Ryzen 5 5600X
- GPU: NVIDIA GeForce RTX 3080 (10GB) or AMD Radeon RX 6800 XT (16GB)
- RAM: 16GB dual-channel
- Storage: 65GB SSD (mandatory)
Assassin’s Creed Black Flag Resynced Extreme Requirements (4K Ultra)
The top-end configuration targets 4K resolution at 60 FPS on the Ultra preset, with Ray Tracing bumped up to Extended and Quality upscaling enabled. This tier is built for high-end rigs only.
- CPU: Intel Core i7-12700K @ 3.6 GHz or AMD Ryzen 7 5700X3D @ 3 GHz
- GPU: NVIDIA GeForce RTX 4090 (24GB) or AMD Radeon RX 7900 XTX (24GB)
- RAM: 32GB recommended for this tier
- Storage: 65GB SSD (mandatory)
VRAM Usage and What GPU You Actually Need
The good news is that Black Flag Resynced is fairly efficient with VRAM compared to other modern open-world releases. At native 1440p, the Very High and Ultra High settings use around 10GB of VRAM, while High and below can run comfortably on 8GB cards. If your GPU has 10GB or more, Very High or Ultra High should run fine at 1440p. If you’re on an 8GB card, sticking to High is the safer choice to avoid stutter from VRAM overflow.
Upscaling and Ray Tracing Support
Black Flag Resynced supports all three major upscaling technologies on PC: NVIDIA DLSS 4.5, AMD FSR 4, and Intel XeSS 3. The game also supports frame generation, HDR, and ultrawide aspect ratios, with an uncapped frame rate in both gameplay and cutscenes. Ray tracing options range from Standard, which is usable even on lower-end hardware, up to Extended for the Ultra preset, which adds more accurate global illumination and reflections. Players without a ray tracing capable GPU can still access software-based lighting options, so lower-end devices are not completely locked out of the visual upgrades.
Why the SSD Requirement Matters
Ubisoft has made SSD storage mandatory for this game, not just recommended. The Steam store page explicitly states the game must be installed on an SSD. At 65GB, the install size itself is reasonable for a 2026 release, but running it from a traditional hard drive risks long load times, texture pop-in, and streaming issues since the game relies on fast asset loading for its open world.
Handheld and Steam Deck Support
Black Flag Resynced also ships with dedicated graphics presets built for handheld devices like the Steam Deck and ROG Ally. A built-in benchmark tool is included as well, which is useful for testing your own hardware or comparing GPU and CPU performance before committing to a specific preset.
