Percentages show how much potential FPS of the stronger component is lost because the other component has a lower FPS ceiling.
🧠Methodology

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.

The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Frequently Asked Questions

1Can the Core i3-8100T and GeForce RTX 4090 run Honkai: Star Rail well?

Yes, the Core i3-8100T paired with the GeForce RTX 4090 can run Honkai: Star Rail smoothly up to 1440p achieving around 67 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 76% below the recommended requirements.

2Is there a more cost-effective setup to run Honkai: Star Rail?

This CPU + GPU combo costs approximately $1708 ($59 CPU (Rank #213 Value) + $1649 GPU (Rank #77 Value)). 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 9950X is a great upgrade option for around $649 (Rank #5 for value).

3Which component should I upgrade first to improve Honkai: Star Rail performance?

For Honkai: Star Rail, upgrading the CPU would have the biggest impact on performance. The Core i3-8100T 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, 4k high, 4k ultra.

4Does this setup support Frame Generation for Honkai: Star Rail?

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.

5What are the minimum and recommended specs for Honkai: Star Rail?

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.

6How accurate are these Honkai: Star Rail FPS estimates for the Core i3-8100T and GeForce RTX 4090?

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.
