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, frame rates range from 27 to 44 FPS depending on quality settings. At 1440p, frame rates range from 27 to 44 FPS. At 4K, frame rates range from 11 to 44 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for Honkai: Star Rail. The Pentium Dual Core T2390 is 87% below minimum CPU requirement.
At lower resolutions (all 1080p settings, all 1440p settings, 4k (low/medium)), the Pentium Dual Core T2390 sets the FPS ceiling. As graphical load increases at (4k ultra), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 4k high.
Approximated average price on current market:
Combo price: $1654. At 1080p Ultra, this combo delivers 27 FPS, equivalent to 0.02 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Pentium Dual Core T2390 sets the ceiling at about 44 FPS, while the GeForce RTX 4090 could reach 174 FPS. In this scenario, the CPU limits the GPU potential by 75% (FPS gap: 130 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 1/12, balanced 1/12.
Your Pentium Dual Core T2390 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 75% | CPU Limits GPU 65% | CPU Limits GPU 51% | CPU Limits GPU 40% |
| 1440p (2K QHD) | CPU Limits GPU 71% | CPU Limits GPU 59% | CPU Limits GPU 43% | CPU Limits GPU 33% |
| 4K (Ultra HD) | CPU Limits GPU 59% | CPU Limits GPU 40% | Balanced | GPU Limits CPU 20% |
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 Pentium Dual Core T2390 and GeForce RTX 4090 will struggle to run Honkai: Star Rail at smooth framerates. At 1080p Ultra, you can expect around 27 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1654 ($5 CPU + $1649 GPU). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 7845HX is a great upgrade option (Rank #1 for value).
For Honkai: Star Rail, upgrading the CPU would have the biggest impact on performance. The Pentium Dual Core T2390 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium. GPU fully utilized at: 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 hardware falls below the minimum requirements for this game, which may result in poor performance.
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.
