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 71 FPS. At 1440p, all settings exceed 64 FPS. At 4K, frame rates range from 50 to 82 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for Honkai: Star Rail. The M4 Max (14 cores) is 79% above the recommended CPU (Core i7).
The M4 Max (14 cores) sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k high, the M4 Max (14 cores) sets the ceiling at about 57 FPS, while the GeForce RTX 4090 could reach 105 FPS. In this scenario, the CPU limits the GPU potential by 46% (FPS gap: 48 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your M4 Max (14 cores) is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 22% | CPU Limits GPU 28% | CPU Limits GPU 27% | CPU Limits GPU 37% |
| 1440p (2K QHD) | CPU Limits GPU 20% | CPU Limits GPU 26% | CPU Limits GPU 29% | CPU Limits GPU 39% |
| 4K (Ultra HD) | CPU Limits GPU 40% | CPU Limits GPU 45% | CPU Limits GPU 46% | CPU Limits GPU 44% |
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.

The M4 Max (14 cores) + GeForce RTX 4090 pairing runs this title with CPU utilization between 4% and 19% and GPU utilization between 26% and 55%. M4 Max (14 cores) keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 39% at 1080p to 50% at 4K, while CPU averages move from 13% to 13%.
Neither component is close to saturation: CPU tops out at 19% and GPU at 55%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.
At 1080p, averages sit around CPU 13% and GPU 39%. At 1440p, that shifts to CPU 14% and GPU 40%, and at 4K it reaches CPU 13% and GPU 50%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 11% (4-18%) and GPU 50% (45-55%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while M4 Max (14 cores) remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the M4 Max (14 cores) and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the M4 Max (14 cores) paired with the GeForce RTX 4090 can run Honkai: Star Rail smoothly up to 1440p achieving around 64 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 79% 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 M4 Max (14 cores) is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Honkai: Star Rail performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
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 M4 Max (14 cores) 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.
