If your result is ready
Keep your settings and revisit only after a driver or game patch changes performance.

Best Assassin's Creed Black Flag Resynced PC Settings
This settings advice is not official Ubisoft guidance. It is a practical approach based on the published presets and the fact that ray tracing is always on, which changes where you should look to recover frame rate.
Bottom line
Because ray tracing cannot be disabled, lean on the upscaler and resolution scaling first, then lower ray tracing quality and shadows before touching textures. On minimum-tier cards, the upscaler is doing real work, so treat it as a core setting, not a last resort.
Stop guessing from spec lists. Run the 60-second check and see exactly where your setup lands, then fix one thing.
What to do next
If your result is borderline
Lower the upscaler quality and ray tracing settings before assuming you need new hardware.
If your result needs an upgrade
Check that your GPU actually supports ray tracing, since that is the most common hard blocker.
Evidence status
inferred: use this page as a current planning guide. If official PC specs or real benchmark data changes the answer, FrameReady should update the recommendation.
Start with the upscaler and resolution
The upscaler is part of the official spec, so use it deliberately rather than avoiding it.
- Set the upscaler to Balanced or Performance on lower-end cards.
- Lower render resolution before cutting core visual settings.
- This matters most on minimum-tier GPUs that already rely on upscaling.
Lower ray tracing quality, since you cannot turn it off
Ray tracing is the biggest GPU cost and it is always on, so its quality slider is your main tool.
- Reduce ray tracing quality before lowering textures.
- Standard ray tracing is the assumed setting at the minimum and recommended tiers.
- Shadows and reflections are the next place to recover frame rate.
Watch VRAM on 8 GB cards
The listed minimum cards have 6 to 8 GB of VRAM, which sets a practical ceiling for textures.
- Lower texture quality on 6 to 8 GB cards if you see stutter or pop-in.
- 12 GB cards have more room to keep textures higher.
- Ray tracing itself also uses VRAM, so budget for both.
Keep the CPU and RAM in mind
The open world and dense sea and city areas can lean on the CPU, and 16 GB RAM is required.
- Close background apps if you are at exactly 16 GB RAM.
- A weak CPU can limit frame rate in busy areas even with a strong GPU.
- Ray tracing also adds some CPU overhead for building the scene.
Keep drivers current
Ray tracing performance is especially sensitive to driver updates.
- Update GPU drivers before launch and after major patches.
- New drivers frequently improve ray tracing performance specifically.
- Recheck settings after a driver or game update rather than assuming they still apply.
Common questions
What settings should I lower first in Black Flag Resynced?
Start with the upscaler and render resolution, then ray tracing quality and shadows. You cannot turn ray tracing off, so lowering its quality is the main lever.
Should I use the upscaler in Black Flag Resynced?
Yes. Ubisoft's own minimum and recommended tiers assume an upscaler set to Balanced. On lower-end cards it is a core setting, not optional.
Why is Black Flag Resynced heavy even on a decent GPU?
Required ray tracing and micropolygon rendering are both demanding. A card that handles older games easily can still struggle here because of the ray tracing load.
