Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Examining the resolution scaling reveals a classic shift in bottleneck behavior. At 1080p with High settings, the average FPS is 176.1. At 1440p, this drops to 112.8 FPS, a reduction of 63.3 FPS. Moving to 4K, the frame rate falls further to 60.4 FPS. The scaling from 1440p to 4K shows a drop of 52.4 FPS. This pattern indicates that as resolution increases, the GPU becomes the primary limiting factor.

The data supports this interpretation when comparing the scaling at different settings. At 1080p with Low settings, the combo produces 354.7 FPS. At 1440p Low, it drops to 220.3 FPS, and at 4K Low, it reaches 114.5 FPS. The percentage drop from 1080p to 1440p is approximately 38%, while from 1440p to 4K is approximately 48%. These are substantial reductions that point directly to the GPU's rendering capabilities being stressed as pixel count increases.

Conversely, the CPU's influence is most apparent at lower resolutions. The fact that 1080p Low can hit 354.7 FPS suggests the processor is not holding the system back. The RTX 3080, with its 10 GB of GDDR6X memory and 760.3 GB/s bandwidth, is a capable GPU, but the data shows it is the component that determines the frame rate ceiling at higher resolutions and settings.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080 resolution, the measured average FPS values are as follows: Low settings produce 354.7 FPS, Medium settings yield 251.5 FPS, High settings deliver 176.1 FPS, and Ultra settings result in 167.4 FPS. The progression from Low to Ultra shows a clear decline, with the most significant drop occurring between Medium and High, a decrease of 75.4 FPS.

For 2560x1440 resolution, the average FPS values are: Low settings at 220.3 FPS, Medium settings at 158.4 FPS, High settings at 112.8 FPS, and Ultra settings at 105.5 FPS. The gap between Medium and High is 45.6 FPS, while the gap between High and Ultra is a smaller 7.3 FPS, suggesting diminishing returns at the higher end.

At 3840x2160 resolution, the average FPS values are: Low settings at 114.5 FPS, Medium settings at 83.9 FPS, High settings at 60.4 FPS, and Ultra settings at 53.3 FPS. The drop from Low to Medium is 30.6 FPS, and from Medium to High is 23.5 FPS. The difference between High and Ultra is 7.1 FPS, indicating that the Ultra preset imposes a similar relative penalty at 4K as it does at 1440p.

These numbers reveal that the scaling between settings is not linear. The largest performance hits occur when moving from Low to Medium and from Medium to High, while the jump from High to Ultra is comparatively modest across all resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 ranks 508th out of 1769 tested combos in Pc Building Simulator. This position places it in the top 29% of all systems tested. Given the high frame rates observed, this ranking might seem lower than expected, but it reflects the broader spectrum of hardware combinations.

The ranking suggests that while this combo is capable of high frame rates, there are many other systems that outperform it. The Ryzen 5 8400F's average benchmark score of 25064 places it in the 82nd percentile, and the RTX 3080's score of 35787 puts it in the 80th percentile. The combo's rank of 508 indicates that the pairing is well-matched in terms of overall capability, but the game's results are influenced by other factors such as memory configuration and storage speed, which are not part of this data set. The rank also implies that systems with more powerful CPUs or GPUs, or both, will achieve higher frame rates, particularly at lower resolutions where the CPU's headroom is more relevant.

Settings Recommendations — which preset gives the best experience per the measured rows

Analyzing the measured FPS rows, the optimal settings depend on the target resolution and desired frame rate. At 1080p, the Medium preset at 251.5 FPS is a strong choice for high-refresh-rate monitors, as it offers a substantial frame rate advantage over High settings (176.1 FPS) while likely maintaining better visual fidelity than Low (354.7 FPS). The jump from Medium to High costs 75.4 FPS, which is a significant trade-off for potentially minor visual gains in a simulation game where detail is often in menus and text.

At 1440p, the Medium preset at 158.4 FPS is the best balance. It provides a smooth experience for most displays, and the drop to High at 112.8 FPS is noticeable but might be acceptable for users prioritizing visual quality. The Ultra preset at 105.5 FPS is still playable, but the 7.3 FPS difference between High and Ultra is minimal, making High the more sensible choice if visual fidelity is paramount.

At 4K, the situation changes. The Medium preset at 83.9 FPS is the highest setting that maintains a frame rate above 60 FPS. The High preset at 60.4 FPS is right at the threshold, while Ultra at 53.3 FPS dips below. For a consistently smooth 4K experience, Medium is the recommended preset, as it provides a 23.5 FPS advantage over High. For users with VRR displays, High might be acceptable, but the data suggests Medium is the safest choice to avoid frame rate dips.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3080 is a high-end GPU from the GeForce 30-series, built on the Ampere architecture with the GA102 chip. It features 8704 shading units, 272 texture mapping units, and 96 raster output units. The GPU operates at a base clock of 1440 MHz and a boost clock of 1710 MHz. Its memory subsystem consists of 10 GB of GDDR6X on a 320-bit bus, providing a bandwidth of 760.3 GB/s. The RTX 3080 also has 68 RT cores and 272 tensor cores, which are relevant for ray tracing and DLSS features, though their impact on Pc Building Simulator is likely minimal given the game's nature.

The GPU's average benchmark score is 35787, placing it in the 80th percentile. Its nearest rival, the AMD Radeon Pro Duo, has a score of 35860 with a delta of -0.2%. The 3DMark Steel Nomad DX12 score of 4407 provides a modern gaming benchmark. In Pc Building Simulator, the GPU's role is evident in the resolution scaling. The 10 GB VRAM is sufficient for the game's textures and models, as evidenced by the stable frame rates at 4K. The boost clock of 1710 MHz allows for consistent performance, but the data shows that the GPU is the primary bottleneck at higher resolutions and settings, particularly when moving from 1440p High to 4K High, where the frame rate drops from 112.8 to 60.4 FPS. This is a clear indication that the RTX 3080's computational throughput, rather than its VRAM capacity, is the limiting factor in this simulation.
