Can My RTX 4080 Super Run Sea of Thieves? FPS Estimate & System Requirements (2026)
Estimated RTX 4080 Super FPS for Sea of Thieves at 1080p, 1440p and 4K, plus the GPU tier you need for 60 FPS.
Last updated 2026-09-09 · evergreen reference
Wondering "can my RTX 4080 Super run Sea of Thieves?" Our estimate puts it at roughly 135 FPS at 1080p, 89 FPS at 1440p and 51 FPS at 4K. The settings that tax Sea of Thieves most are water rendering and high/ultra ship detail. FPS figures are editorial estimates from a transparent demand-tier model (TechPowerUp relative-performance indices, retrieved 2026-08-29), not benchmarks. Verify with your own hardware.
Estimated RTX 4080 Super FPS for Sea of Thieves
Frame-rate estimate by resolution. "Estimate" means modeled, not measured.
Bottom line
The RTX 4080 Super is a natural fit for Sea of Thieves at 1440p: about 89 FPS there and 135 FPS at 1080p. Native 4K is possible only with upscaling, not smooth Ultra. Note that Sea of Thieves is CPU-bound at high frame rates, so on a RTX 4080 Super the processor — not the GPU — decides how high your average FPS actually climbs.
RTX 4080 Super FPS by resolution
Modeled Sea of Thieves performance on a RTX 4080 Super (tier 5/9).
| Resolution | Est. FPS | Verdict |
|---|---|---|
| 1080p (Full HD) | 135 | Excellent — high/ultra settings |
| 1440p (QHD) | 89 | Smooth 60+ FPS |
| 4K (UHD) | 51 | Playable on low–medium |
Verdict for the RTX 4080 Super + Sea of Thieves pairing
What to expect and where to aim.
Best target resolution
On a RTX 4080 Super, aim for 1440p (QHD) in Sea of Thieves. The RTX 4080 Super is a natural fit for Sea of Thieves at 1440p: about 89 FPS there and 135 FPS at 1080p. Native 4K is possible only with upscaling, not smooth Ultra. Note that Sea of Thieves is CPU-bound at high frame rates, so on a RTX 4080 Super the processor — not the GPU — decides how high your average FPS actually climbs.
Settings to hit 60 FPS on your RTX 4080 Super
A starting point tuned to this exact pairing; adjust to taste.
CPU, not your RTX 4080 Super, is the limit
Unlike most titles, Sea of Thieves leans on the processor more than the RTX 4080 Super. At 1080p you can already be CPU-limited, so a faster RTX 4080 Super gives diminishing returns — spend the budget on a stronger CPU or faster RAM. The RTX 4080 Super has more than enough pixel-pushing power for Sea of Thieves.
You have headroom to spare
With ~135 FPS at 1080p, runs fine on mid GPUs at 1080p. You can also enable the game's quality upscaler for crisper 1440p without sacrificing smoothness.
Bottleneck analysis: RTX 4080 Super + Sea of Thieves
Why this pairing performs the way it does.
What actually bottlenecks Sea of Thieves on a RTX 4080 Super
The limiting factor for this specific pairing is your CPU. Sea of Thieves spends most of its frame budget on the processor (entity counts, physics, draw calls), so the RTX 4080 Super — a flagship card at relative index 88/100 — rarely reaches its own limit. Upgrading the CPU yields more FPS than upgrading the GPU here.
What GPU tier Sea of Thieves needs
For ~60 FPS targets, based on its demand tier.
Recommended GPU tiers
Nearest real GPUs for each target (estimate).
| Target | Approx. GPU tier needed | Example GPU |
|---|---|---|
| 30 FPS @ 1080p (minimum) | index ≈ 17 | GTX 1650 |
| 60 FPS @ 1080p (recommended) | index ≈ 34 | GTX 1660 Super |
| 60 FPS @ 1440p (high) | index ≈ 52 | RX 6600 XT |
How this estimate is calculated
Full transparency on the model.
Method
Sea of Thieves is assigned a hardware-demand tier 5/9 from its published requirements (or release era + genre). Each GPU has a relative-performance index (RTX 4090 = 100, source TechPowerUp). FPS ≈ 60 × (GPU index ÷ required index)^0.85, then scaled ×0.66 for 1440p and ×0.38 for 4K. FPS figures are editorial estimates from a transparent demand-tier model (TechPowerUp relative-performance indices, retrieved 2026-08-29), not benchmarks. Verify with your own hardware.
