Being turn-based, extreme FPS is less critical here. The game features high-fidelity models and uses considerable storage for audio and cutscenes. 8GB of RAM is recommended for smooth operation.
This game has a built-in FPS cap of 60 FPS
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 109 FPS. At 1440p, all settings exceed 95 FPS. At 4K, all settings exceed 76 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for Honkai: Star Rail. The Core Ultra 9 275HX is 160% above the recommended CPU (Core i7).
The GeForce RTX 4090 sets the FPS ceiling at all 1080p settings, all 1440p settings, 4k (low/medium), while the Core Ultra 9 275HX still has additional frame-generation headroom. The FPS ceiling is closely matched at 4k (high/ultra).
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p medium, the GeForce RTX 4090 sets the ceiling at about 93 FPS, while the Core Ultra 9 275HX has headroom up to 121 FPS. In this scenario, the GPU limits the CPU potential by 23% (FPS gap: 28 FPS). Overall distribution: GPU limits 10/12 cells, CPU limits 0/12, balanced 2/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Core Ultra 9 275HX frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 22% | GPU Limits CPU 22% | GPU Limits CPU 22% | GPU Limits CPU 14% |
| 1440p (2K QHD) | GPU Limits CPU 22% | GPU Limits CPU 23% | GPU Limits CPU 20% | GPU Limits CPU 13% |
| 4K (Ultra HD) | GPU Limits CPU 13% | GPU Limits CPU 15% | Balanced | Balanced |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 160% above and your GPU is 279% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Core Ultra 9 275HX paired with the GeForce RTX 4090 can run Honkai: Star Rail smoothly up to 4k achieving around 76 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 160% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Honkai: Star Rail performance right now. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium.
Honkai: Star Rail does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Honkai: Star Rail requires at minimum a Core i3 (CPU) and GeForce GTX 650 (GPU) with 6 GB RAM and 20 GB storage. For the recommended experience, you need a Core i7 and GeForce GTX 1060 with 8 GB RAM. Your Core Ultra 9 275HX and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Honkai: Star Rail FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
