The percentage estimates how much of the stronger component's capability goes unused because of the other one.

It makes no difference which processor you have: with the RX 580 8GB in Assassin's Creed Black Flag Resynced the graphics card is always the brake. Swapping CPU would not gain you a single frame — put the money into the card.

FSR performance: FPS with AI upscaling

Upscaling renders Assassin's Creed Black Flag Resynced at a lower internal resolution and reconstructs the image, so you trade a little sharpness for extra frames. These are the estimated figures for the RX 580 8GB with FSR enabled, starting from its native Ultra FPS.

About ray tracing: every figure on this page is with ray tracing off. The RX 580 8GB has no dedicated hardware for it, so it is an option best left disabled.

Estimated figures. The real gain varies by game and by the version of the technology.

Is the CPU or the graphics card holding you back?

These FPS assume a mid-range CPU that isn't a bottleneck — roughly a Intel Core i5-13400 — and 16 GB of RAM.

Here the graphics card is the brake: the RX 580 8GB is what caps the frame rate in Assassin's Creed Black Flag Resynced. A faster processor would hardly change the result.

Frequently asked questions about Assassin's Creed Black Flag Resynced on the RX 580 8GB

How many FPS does the RX 580 8GB get in Assassin's Creed Black Flag Resynced at 1080p?
The RX 580 8GB averages 23 FPS in Assassin's Creed Black Flag Resynced at 1080p on Ultra settings. Dropping to High takes it to around 30 FPS, and Low reaches roughly 51 FPS.
What about 1440p and 4K?
On Ultra, the RX 580 8GB manages around 15 FPS at 1440p and around 6 FPS at 4K. Those are native figures: switching on AI upscaling lifts both considerably.
Can the RX 580 8GB run Assassin's Creed Black Flag Resynced at 60 FPS?
Not on Ultra — it averages below 60 FPS at every resolution. Dropping to Low at 1080p gets the RX 580 8GB to about 51 FPS in Assassin's Creed Black Flag Resynced, and AI upscaling helps close the gap to 60.
Do these Assassin's Creed Black Flag Resynced figures include upscaling or ray tracing?
No. Every FPS figure on this page is native, with no AI upscaling and with ray tracing off. The RX 580 8GB has no ray tracing hardware, so that option is off the table for this card.
How many FPS do I gain by turning on FSR in Assassin's Creed Black Flag Resynced?
At 4K, FSR on Quality mode takes the RX 580 8GB from around 6 native FPS to an estimated 9 FPS. Performance mode goes higher still, at the cost of some image sharpness.
What processor do I need to pair with the RX 580 8GB?
The figures on this page assume a Intel Core i5-13400, a mid-range processor that does not bottleneck the card. What matters with the RX 580 8GB is that the CPU is not far below it: past that class, moving up a processor barely changes FPS at higher resolutions.
