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

The measured FPS data for Pc Building Simulator shows a predictable but steep scaling curve as resolution increases. At 1920x1080 with Ultra settings, the AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 3070 combination delivers 144.7 FPS. Moving to 2560x1440 Ultra drops that to 89.5 FPS, a reduction of roughly 38%. At 3840x2160 Ultra, the average falls to 47 FPS, which is about 68% lower than the 1080p result. This scaling pattern is consistent with a GPU-bound scenario at higher resolutions — the frame rate drops are proportionally larger than the pixel count increases would suggest if the CPU were the limiting factor.

The Low settings row tells a different story. At 1080p Low, the system hits 302.8 FPS, but at 1440p Low it falls to 188.3 FPS, and at 4K Low it drops to 98.6 FPS. The gap between Low and Ultra at 1080p is substantial: 302.8 FPS versus 144.7 FPS, a difference of over 2x. This wide spread indicates that graphics settings have a major impact on performance, which points to the GPU as the primary bottleneck when settings are raised. The CPU has ample headroom at lower settings, as evidenced by the very high frame rates at 1080p Low.

Looking at the Medium preset, the scaling from 1080p (215.3 FPS) to 1440p (133.8 FPS) to 4K (72.4 FPS) shows a nearly linear relationship with pixel count. This is classic GPU-bound behavior. The High preset follows a similar pattern: 150.4 FPS at 1080p, 94.9 FPS at 1440p, and 50.9 FPS at 4K. The consistency of these ratios across presets suggests that the rendering pipeline is well-balanced for this title, with no sudden cliff or unexpected stall as resolution increases.

The data indicates that at 1080p, even with Ultra settings, the system is not fully utilizing the CPU's potential. The Ryzen 7 5800XT can push well beyond 144 FPS in this game when the GPU is not the constraint, as shown by the 302.8 FPS Low result. At 4K Ultra, the GPU is clearly the limiting component — the 47 FPS result is far below what the CPU alone could deliver. For users targeting 4K, the RTX 3070 is the binding constraint; for 1080p, the CPU has significant headroom left on the table.

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

The NVIDIA GeForce RTX 3070 brings 8 GB of GDDR6 memory on a 256-bit bus, yielding 448.0 GB/s of bandwidth. In Pc Building Simulator, a simulation title with complex UI elements and 3D component models, this memory configuration appears sufficient at all tested settings. The fact that the 4K Ultra preset still achieves 47 FPS suggests that VRAM capacity is not causing a performance cliff — the GPU is compute-bound rather than memory-limited.

The RTX 3070's clock behavior is notable: a base clock of 1500 MHz and a boost clock of 1725 MHz. The memory runs at 1750 MHz, which translates to 14 Gbps effective. These clocks, combined with the Ampere architecture's 5888 shading units, produce 20.31 TFLOPS of FP32 compute. In this game, the scaling from Low to Ultra at 4K (98.6 FPS down to 47 FPS) shows that the GPU's raw throughput is the deciding factor at high settings. The 184 texture mapping units and 96 ROPs handle the game's texture-heavy simulation interface without obvious bottlenecks.

The RTX 3070's benchmark scores provide context for its gaming performance. Its Passmark G3D score is 22214, placing it in the 72nd percentile of all GPUs. The 3DMark Steel Nomad DX12 score of 3162 indicates strong DirectX 12 performance, which aligns with the game's support for modern APIs. The GPU's nearest rivals in the benchmark database include the AMD Radeon RX 6600 XT (scoring 27985, a 0.9% delta) and the NVIDIA GeForce GTX 980 Ti (scoring 27956, a 1% delta). The RTX 3070 outperforms both in average benchmark score, though by less than 1% — a margin that would be imperceptible in real-world gaming.

The 8 GB VRAM capacity deserves scrutiny for 4K gaming. While the measured data shows playable frame rates at 4K High (50.9 FPS), the gap between 4K Medium (72.4 FPS) and 4K High (50.9 FPS) is larger than the 1440p equivalent gap (133.8 FPS to 94.9 FPS). This suggests that at 4K, the higher settings are consuming more memory bandwidth, and the 448.0 GB/s figure is approaching its practical limit. The GPU's 220 W TDP and dual-slot design indicate it is a power-hungry part, but the measured FPS data shows no thermal throttling artifacts — the scaling is smooth and predictable.

A: The FPS scaling from Low to Ultra at a fixed resolution is steep (302.8 to 144.7 FPS at 1080p), indicating strong GPU sensitivity. The CPU's 8 cores and 16 threads provide ample parallelism for this simulation genre, but the rendering load is what drives frame rate differences.

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

At 1920x1080, the full settings range was tested. Low produces 302.8 FPS, Medium delivers 215.3 FPS, High drops to 150.4 FPS, and Ultra bottoms out at 144.7 FPS. The jump from Low to Medium is 87.5 FPS, while the jump from High to Ultra is only 5.7 FPS. This suggests that the High to Ultra transition adds minimal visual benefit relative to its performance cost.

At 2560x1440, the pattern shifts. Low gives 188.3 FPS, Medium provides 133.8 FPS, High achieves 94.9 FPS, and Ultra reaches 89.5 FPS. The delta between High and Ultra narrows to 5.4 FPS, similar to the 1080p gap. The Medium to High drop is 38.9 FPS, which is the largest single-step decline at this resolution, indicating that High settings impose a significant rendering load.

At 3840x2160, the results are more constrained. Low still manages 98.6 FPS, Medium drops to 72.4 FPS, High falls to 50.9 FPS, and Ultra limps to 47 FPS. The Medium to High gap is 21.5 FPS, while the High to Ultra gap is just 3.9 FPS. At 4K, the system cannot maintain 60 FPS on High or Ultra, making those presets marginal for smooth gameplay.

The resolution scaling from 1440p to 4K at each setting shows consistent drops: Low falls by 89.7 FPS, Medium by 61.4 FPS, High by 44 FPS, and Ultra by 42.5 FPS. This pattern indicates that as settings increase, the absolute FPS loss from resolution scaling decreases, but the percentage loss increases. The RTX 3070's 8 GB VRAM and 448.0 GB/s bandwidth are sufficient to avoid catastrophic failure, but the compute units are clearly saturated at 4K High and Ultra.

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

Based strictly on the measured data, the Medium preset provides the most balanced experience across all resolutions. At 1080p Medium, the system delivers 215.3 FPS, which exceeds any display's refresh rate in practical use. At 1440p Medium, 133.8 FPS is smooth for high-refresh monitors. Even at 4K Medium, 72.4 FPS remains above the 60 FPS threshold, making it the only preset that achieves playable frame rates at every tested resolution.

The High preset is a reasonable alternative for users prioritizing visual quality over frame rate stability. At 1080p High, 150.4 FPS is excellent. At 1440p High, 94.9 FPS is still very good. However, 4K High drops to 50.9 FPS, which may introduce noticeable stutter on 60 Hz displays. The Ultra preset offers marginal gains over High — the difference in FPS is only 5.7 at 1080p, 5.4 at 1440p, and 3.9 at 4K — yet it consistently produces the lowest frame rates of any preset.

For users with 1080p displays, the High preset is the best choice. The 150.4 FPS result is only slightly below the Ultra result of 144.7 FPS, and the visual difference between High and Ultra in a simulation game is likely minimal. For 1440p users, Medium at 133.8 FPS is the sweet spot, as High drops to 94.9 FPS — still playable but a significant step down. For 4K users, Medium is the only viable option if 60 FPS is the target, as High and Ultra both fall below 51 FPS.

The Low preset, while delivering the highest frame rates (302.8 FPS at 1080p, 188.3 FPS at 1440p, 98.6 FPS at 4K), sacrifices too much visual fidelity for a simulation game where readability of component models matters. The data suggests that Medium is the recommended default, with High as an option for 1080p and 1440p users who want better visuals and can tolerate frame rates above 90 FPS.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. Its base clock is 3.80 GHz with a boost clock of 4.80 GHz, and it features 32 MB of L3 cache. In Pc Building Simulator, the CPU's role is to manage the simulation logic, component interactions, and UI updates while the GPU handles rendering. The measured frame rates at 1080p Low (302.8 FPS) demonstrate that the CPU is not a limiting factor in this title — it can feed the GPU far more frames than the RTX 3070 can render at high settings.

The CPU's benchmark results support this interpretation. Its Cinebench R23 multicore score of 23794 and single-core score of 3359 indicate strong performance in both threaded and single-threaded workloads. The 3DMark single-thread score of 959 and 16-thread score of 7683 show that the processor scales well with thread count. In a simulation game, the 8 cores and 16 threads allow the game engine to distribute simulation tasks across multiple threads, preventing CPU bottlenecks that could limit frame rates.

The CPU's 86th percentile ranking among all CPUs, with an average benchmark score of 29774, places it in the upper tier of desktop processors. Its nearest rivals include the AMD Ryzen 7 PRO 5755GE (scoring 29740, a 0.1% delta) and the AMD Ryzen 7 6800HS (scoring 29856, a -0.3% delta). These differences are negligible in real-world terms, but the 5800XT's 4.80 GHz boost clock gives it an edge in single-threaded tasks that simulation games often rely on.

The CPU's memory bandwidth of 51.2 GB/s over a dual-channel DDR4 interface is adequate for this game. The 32 MB L3 cache helps keep frequently accessed simulation data close to the cores, reducing memory latency. The 105 W TDP and AMD Socket AM4 compatibility make it a straightforward drop-in for existing systems. The CPU's launch MSRP is $249, and it was released on 2024-07-30, making it a relatively recent addition to the 5000 series lineup.

In terms of FPS impact, the data shows that the CPU is not the bottleneck at any tested resolution or setting. The proof lies in the scaling: at 1080p Low, the system hits 302.8 FPS, which is far above what the GPU can sustain at higher settings. If the CPU were limiting, we would expect to see similar frame rates across different settings at the same resolution. Instead, the FPS varies dramatically with settings (302.8 to 144.7 FPS at 1080p), confirming that the GPU is the primary performance driver. The Ryzen 7 5800XT provides ample headroom for this game, making it a suitable match for the RTX 3070 in Pc Building Simulator.
