Remastered pirate adventure ships with modern upscaling and engine overhaul

The remake runs on the latest version of Ubisoft's Anvil engine, which rebuilds the game's foundation for seamless open-world traversal and improved graphics. The PC version supports NVIDIA DLSS 4.5, a technology that uses dynamic multi-frame generation to boost visual fidelity and speed. This architecture allows the game to scale efficiently across different resolution settings while maintaining visual clarity.

Game Engine: Anvil (latest version)
Graphics Technology: NVIDIA DLSS 4.5, Ray Tracing
GPU Tested: Gainward GeForce RTX 5070 Snow OC
GPU Architecture: NVIDIA Blackwell
GPU VRAM: 12GB GDDR7

We tested the title using the Gainward GeForce RTX 5070 Snow OC, a card built on the new NVIDIA Blackwell architecture. This GPU features 12GB of GDDR7 memory and supports clock speeds up to 2542MHz with a memory speed of 28Gbps. These specifications provide the necessary bandwidth and processing power to handle the demands of the remastered engine and advanced upscaling features.

Performance benchmarks show that the Gainward RTX 5070 delivers exceptional frame rates when utilizing DLSS 4.5 6X Frame Generation with Ray Tracing enabled. At 1080p, the system achieves an average of 255 FPS, while 2K resolution yields 242 FPS. The card also reaches 185 FPS at 4K, effectively removing performance bottlenecks at higher resolutions.

The game also introduces new content such as 3D spatial audio, expanded pirate songs, and new playable crew officers, while removing the modern-day storyline in favor of in-game Animus anomalies. We looked at GAINWARD GeForce RTX 5060 Ti 8GB earlier while tracking Ubisoft launches, noting similar support for DLSS 4.5 in recent hardware releases. Ubisoft confirmed the release with the statement: Assassin's Creed IV Black Flag Remastered is live! Gainward RTX 5070 Snow OC Performance Test.
