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.

A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Performance Summary

The Core i3-8121U + GeForce RTX 4090 pairing runs this title with CPU utilization between 29% and 74% and GPU utilization between 32% and 100%. Core i3-8121U keeps significant headroom across presets, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 61% at 1080p to 81% at 4K, while CPU averages move from 54% to 42%.

Load Interpretation

From a utilization perspective, this is a GPU-heavy load profile. At 1440p (2K QHD) Ultra, the GeForce RTX 4090 averages 100% usage (100-100%), while the Core i3-8121U stays at 46% (36-55%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.

Resolution Scaling

At 1080p, averages sit around CPU 54% and GPU 61%. At 1440p, that shifts to CPU 44% and GPU 80%, and at 4K it reaches CPU 42% and GPU 81%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.

Optimal Settings Recommendation

1440p (2K QHD) High is the most balanced preset based on this dataset. It runs around CPU 40% (31-49%) and GPU 94% (91-97%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i3-8121U remains stable for consistent frame delivery.

Upgrade Insight

Upgrade priority should be the GPU. The GeForce RTX 4090 reaches 100% average load at 1440p (2K QHD) Ultra while the Core i3-8121U still has headroom, so a faster graphics card would deliver the largest uplift.

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.

  • High GPU Load: You typically want to see High GPU Utilization (90%+) and moderate CPU usage when visual settings are heavy. This indicates the graphics pipeline is under strong load, but the exact FPS limiter should still be confirmed by the FPS ceiling analysis.
  • High CPU Load: If you see High CPU Utilization (85%+) paired with lower GPU utilization, the processor is handling a disproportionate share of frame preparation and game logic. That can point to CPU-side pressure, but it should not be treated as a direct replacement for FPS ceiling analysis.
  • Low CPU and GPU Load: If both CPU and GPU utilization are relatively low, it means the hardware is waiting on something else. This could be a game engine limitation, poorly optimized code, or an artificial framerate cap like VSync holding performance back. It does not mean both parts are equally fast in FPS terms.

Frequently Asked Questions

1Can the Core i3-8121U and GeForce RTX 4090 run Dead by Daylight well?

Yes, the Core i3-8121U paired with the GeForce RTX 4090 can run Dead by Daylight smoothly up to 1440p achieving around 87 FPS at Ultra quality. Your GPU is 692% above the recommended specs, and your CPU is 20% below the recommended requirements.

2Is there a more cost-effective setup to run Dead by Daylight?

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.

3Which component should I upgrade first to improve Dead by Daylight performance?

For Dead by Daylight, upgrading the CPU would have the biggest impact on performance. The Core i3-8121U 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 Dead by Daylight?

Dead by Daylight 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 Dead by Daylight?

Dead by Daylight requires at minimum a Core i3-4170 (CPU) and GeForce GTX 460 (GPU) with 8 GB RAM and 50 GB storage. For the recommended experience, you need a Core i3-4170 and GeForce GTX 760 with 8 GB RAM. Your hardware falls below the minimum requirements for this game, which may result in poor performance.

6How accurate are these Dead by Daylight FPS estimates for the Core i3-8121U and GeForce RTX 4090?

These Dead by Daylight 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.
