Assassin's Creed Black Flag Resynced benchmark on RTX 4090: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Assassin's Creed Black Flag Resynced FPS with a RTX 4090 and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 127FPS min 82Excellent | 112FPS min 79Good | 83FPS min 72Good |
| High | 165FPS min 107Excellent | 145FPS min 102Excellent | 108FPS min 94Good |
| Medium | 216FPS min 140Excellent | 190FPS min 133Excellent | 141FPS min 123Excellent |
| Low | 279FPS min 181Excellent | 245FPS min 172Excellent | 183FPS min 159Excellent |
| Bottleneck (estimated) | CPU 38% | CPU 29% | balanced |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the Intel Core i9-14900K downwards the processor becomes the brake on the RTX 4090. There is 11% between the slowest and fastest CPU in the table. One caveat: this is at 1080p, where the CPU weighs most. At 1440p and 4K the graphics card takes over and the processor stops mattering.
DLSS 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 RTX 4090 with DLSS enabled, starting from its native Ultra FPS.
| Resolution | Native | DLSS Quality | DLSS Performance | + Frame generation |
|---|---|---|---|---|
| 1080p | 127 | 159 | 184 | 270 |
| 1440p | 112 | 151 | 185 | 257 |
| 4K | 83 | 120 | 154 | 204 |
Frame generation inserts intermediate frames: it raises the smoothness you see on screen, but it does not reduce input latency, so use it selectively in competitive games.
About ray tracing: every figure on this page is with ray tracing off. The RTX 4090 does have dedicated hardware for it, so you can turn it on in games that implement it. The FPS cost swings widely depending on how much ray tracing each title uses, and DLSS is exactly what people lean on to pay for it.
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.
With that CPU, the RTX 4090 has headroom to spare in Assassin's Creed Black Flag Resynced: the processor runs out before the graphics card does. A faster processor would gain you FPS; a stronger graphics card would barely help.
Is the RTX 4090 Enough for Assassin's Creed Black Flag Resynced?
The RTX 4090 delivers 127 FPS at 1080p Ultra in Assassin's Creed Black Flag Resynced. More than enough for 144Hz. You can comfortably play at 1440p.
At 1440p it gets 112 FPS and at 4K 83 FPS at Ultra quality.
This GPU is more than enough — you can play at 1440p or 4K comfortably
