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

The measured FPS data reveals a dramatic scaling curve as resolution increases, and the pattern strongly suggests the GPU is the dominant constraint at higher resolutions. At 1080p Ultra, the combination delivers 145 FPS, but stepping up to 1440p Ultra drops that to 89.6 FPS — a reduction of roughly 38%. Pushing further to 4K Ultra yields 47.8 FPS, which is about 67% below the 1080p Ultra result. This steep decline is classic GPU-bound behavior, where pixel throughput becomes the bottleneck.

The Low preset tells an even more revealing story. At 1080p Low, the system hits 305.9 FPS, which is a phenomenal number for a simulation title. At 1440p Low, it still manages 191.7 FPS, and at 4K Low, it holds onto 102.3 FPS. The fact that 4K Low exceeds 100 FPS while 4K Ultra falls below 50 FPS indicates that the graphics settings are having a massive impact on frame times, far more than the resolution change alone. This suggests that the game's Ultra preset introduces effects that heavily tax the Radeon RX 7700 XT's shading units and ROPs.

Looking at the intermediate settings, the scaling is remarkably consistent. From 1080p Medium (219.3 FPS) to 1440p Medium (134.6 FPS) is a 39% drop, and from 1440p Medium to 4K Medium (75 FPS) is a 44% drop. This near-linear scaling with pixel count indicates that the limiting component responds predictably to workload increases, with no sudden cliff or stutter suggesting CPU limitations. The Ryzen 7 5800XT's 8 cores and 16 threads appear to be feeding the GPU adequately even at lower resolutions, where CPU overhead typically becomes more visible.

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

The AMD Radeon RX 7700 XT brings 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. In a simulation game like Pc Building Simulator, where scene complexity can vary wildly depending on how many components and systems are rendered on screen, this memory configuration appears well-suited. The 4K Medium result of 75 FPS versus the 4K High result of 53.3 FPS suggests that the graphics memory isn't being exhausted at medium settings, but the higher preset's additional texture and shading demands cut deeply into performance.

The GPU's clock behavior is notable for this title. The boost clock of 2544 MHz and game clock of 2171 MHz are the specifications that matter for sustained gaming loads. The data shows that at 1080p Low, the system achieves 305.9 FPS, which is likely pushing near the limits of what the game engine can render per frame. At that frame rate, the GPU is almost certainly not running at its maximum boost clock, because the workload per frame is so light. Conversely, at 4K Ultra with 47.8 FPS, the GPU is fully saturated and likely holding boost clocks steadily, yet still cannot break 60 FPS.

The 96 ROPs and 3456 shading units are the key compute resources that determine how well the RX 7700 XT handles the pixel-heavy presets. The gap between 4K High (53.3 FPS) and 4K Medium (75 FPS) is a 29% improvement, which is substantial. This indicates that the High preset adds render features that disproportionately load the ROPs, likely through increased overdraw or post-processing effects. The FP32 throughput of 35.17 TFLOPS gives the card ample raw compute for simulation logic, but the frame rate data shows that pixel fill rate is the constraining factor at 4K.

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

The AMD Ryzen 7 5800XT is a Zen 3 part built on TSMC's 7 nm process, featuring 8 cores and 16 threads. Its base clock of 3.80 GHz and boost clock of 4.80 GHz provide substantial single-threaded performance, as evidenced by the 3DMark single-thread score of 959 and Cinebench R23 single-core score of 3359. In Pc Building Simulator, where the simulation logic tracks dozens of components and their interactions, this single-thread capability is likely what keeps the game running smoothly at high frame rates.

The multi-threaded performance is equally robust, with a Cinebench R23 multicore score of 23794 and a 3DMark 16-thread score of 7683. The game's simulation loop can leverage multiple threads for physics and AI calculations, and the fact that 1080p Low achieves 305.9 FPS suggests that the CPU is not creating a bottleneck at lower resolutions. If the CPU were the limiting factor, we would expect to see similar frame rates across different resolutions at the same preset, but the data shows clearly that resolution changes have a profound effect.

The L3 cache of 32 MB is worth considering in this context. Pc Building Simulator's simulation state, which includes component temperatures, power draws, and compatibility checks, benefits from having that data in fast cache rather than main memory. The memory bandwidth of 51.2 GB/s from dual-channel DDR4 is adequate for the game's needs, as evidenced by the consistent scaling from 1080p to 1440p. The CPU's percentile rank of 86 against all CPUs indicates it sits comfortably in the upper tier of processors, which aligns with the observed ability to feed the RX 7700 XT at high frame rates.

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

For 1080p displays, the High preset at 151.3 FPS is arguably the sweet spot. It delivers a frame rate that is nearly three times the 60 FPS threshold while providing the visual fidelity that most users expect from a modern game. The Ultra preset at 1080p drops to 145 FPS, which is only a 4% reduction, so if the visual differences between High and Ultra matter to you, the cost is minimal. However, the Low preset at 305.9 FPS is overkill for most displays, and Medium at 219.3 FPS is still far beyond what typical 144 Hz monitors can display.

At 1440p, the Medium preset at 134.6 FPS provides an excellent balance. It maintains a frame rate that is well above 120 FPS, making it ideal for high-refresh-rate monitors. The High preset at 99.9 FPS is still very smooth and likely the best choice if you prioritize image quality over raw speed. The Ultra preset at 89.6 FPS is playable but begins to approach the territory where frame time consistency becomes more important than peak average. Low at 191.7 FPS is unnecessary for most users.

For 4K, the situation is more constrained. The Medium preset at 75 FPS is the only option that comfortably exceeds 60 FPS, making it the recommended choice for 4K gaming. High at 53.3 FPS is playable on VRR displays but will show occasional dips below 60. Ultra at 47.8 FPS is best avoided unless you are willing to accept a cinematic frame rate. Low at 102.3 FPS shows that the hardware can handle 4K when the visual load is reduced, but the medium preset offers the best compromise between fidelity and frame rate.

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

At 1920x1080, the measured average FPS values are as follows: Low preset runs at 305.9 FPS, Medium at 219.3 FPS, High at 151.3 FPS, and Ultra at 145 FPS. The gap between Medium and High is 68 FPS, while the gap between High and Ultra is relatively small at 6.3 FPS. This suggests that the High preset captures most of the visual benefits without the performance penalty of Ultra.

Moving to 2560x1440, the results are 191.7 FPS on Low, 134.6 FPS on Medium, 99.9 FPS on High, and 89.6 FPS on Ultra. The drop from Low to Medium is 57.1 FPS, from Medium to High is 34.7 FPS, and from High to Ultra is 10.3 FPS. The diminishing returns between High and Ultra are consistent with the 1080p pattern.

At 3840x2160, the measured values are 102.3 FPS on Low, 75 FPS on Medium, 53.3 FPS on High, and 47.8 FPS on Ultra. The transition from Low to Medium costs 27.3 FPS, Medium to High costs 21.7 FPS, and High to Ultra costs only 5.5 FPS. The Ultra preset at 4K is within 5.5 FPS of High, making High a questionable choice if you are already considering Ultra.

The complete picture shows that this combination of AMD Ryzen 7 5800XT and AMD Radeon RX 7700 XT is highly capable for Pc Building Simulator at 1080p and 1440p, with excellent frame rates across all settings. At 4K, the system is playable but requires settings management to maintain smooth performance. The data indicates a well-balanced pairing where the CPU and GPU complement each other effectively for this simulation title.
