The data reveals a balanced pairing: neither component dramatically bottlenecks the other in Pc Building Simulator's workload, though the GPU's higher percentile ranking suggests it carries more weight in determining overall frame rates.

# Settings Recommendations

The measured FPS data strongly favors Medium or High settings for the best experience across resolutions. At 1080p, Medium delivers 261.5 FPS while High reaches 181.7 FPS, both well above the 144Hz refresh rates common in modern displays. Ultra at 1080p still provides 172.4 FPS, but the drop from High to Ultra is only 9.3 FPS, suggesting diminishing returns for the extra visual load. At 1440p, High delivers 115.7 FPS, which is ideal for 120Hz monitors, while Medium offers 163 FPS for those with higher refresh displays. Ultra at 1440p drops to 109.9 FPS, still playable but approaching the threshold where frame pacing becomes noticeable.

For 4K displays, High produces 58.7 FPS, just under the 60 FPS target that many consider the minimum for smooth gameplay. Medium at 4K achieves 86.4 FPS, which is the sweet spot for Ultra HD gaming with this hardware. Low settings at 4K reach 123.7 FPS, but the visual compromise in a simulation game that relies heavily on reading text and UI elements makes this less desirable. The recommendation is Medium at 4K, High at 1440p, and Medium or High at 1080p depending on whether the user prioritizes maximum frame rates or visual fidelity.

# Resolution Scaling

The FPS scaling from 1080p to 4K reveals a system that is clearly GPU-limited at higher resolutions. At High settings, the transition from 1080p (181.7 FPS) to 1440p (115.7 FPS) represents a 36.3% performance drop, while moving from 1440p to 4K (58.7 FPS) costs another 49.3%. This steep decline indicates that the RTX 3080 Ti's rendering throughput, not the CPU, becomes the limiting factor as pixel count increases. The GPU's 912.4 GB/s memory bandwidth and 34.10 TFLOPS of FP32 compute are being fully exercised at 4K.

At Low settings, the scaling pattern shifts. The jump from 1080p (351.1 FPS) to 1440p (231.3 FPS) is a 34.1% reduction, but from 1440p to 4K (123.7 FPS) the drop is 46.5%. This still shows GPU dominance, though the absolute numbers at 1080p approach 350 FPS, which is near the practical ceiling for many display interfaces. The i5-12400F's 6 cores and 12 threads can feed frames fast enough at lower resolutions, but the rendering workload at 4K overwhelms the GPU regardless of settings. The data confirms that users wanting 4K gameplay should expect roughly one-third of the 1080p frame rate at identical settings.

# Measured FPS Breakdown

At 1920x1080, the combo produces 351.1 FPS on Low, 261.5 FPS on Medium, 181.7 FPS on High, and 172.4 FPS on Ultra. The gap between High and Ultra is just 9.3 FPS, making Ultra a marginal upgrade at this resolution. At 2560x1440, the results are 231.3 FPS on Low, 163 FPS on Medium, 115.7 FPS on High, and 109.9 FPS on Ultra. The High-to-Ultra delta narrows to 5.8 FPS, further reinforcing that Ultra provides minimal benefit. At 3840x2160, the numbers drop to 123.7 FPS on Low, 86.4 FPS on Medium, 58.7 FPS on High, and 57.4 FPS on Ultra. The High-to-Ultra difference shrinks to just 1.3 FPS, making Ultra essentially indistinguishable from High in performance terms.

The pattern across all resolutions shows that Medium settings offer the largest performance headroom increase over Low, while High provides a significant visual upgrade with modest FPS cost. Ultra consistently delivers less than 10% additional frames over High, and in the 4K case, less than 3%. This suggests the game's Ultra preset includes effects that heavily tax the GPU without proportional visual returns. For competitive play, Low at 1440p (231.3 FPS) or 1080p (351.1 FPS) would be the choice, but for a simulation game where immersion matters more, Medium at 4K (86.4 FPS) or High at 1440p (115.7 FPS) offers the best balance.

# GPU Role

The RTX 3080 Ti brings 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. This memory configuration is crucial for Pc Building Simulator, which renders detailed 3D models of PC components and shop environments at high resolutions. The 80 RT cores and 320 tensor cores provide hardware acceleration for any ray-traced or AI-enhanced effects, though the measured FPS data suggests the game primarily relies on traditional rasterization. The GPU's 10,240 shading units and 112 ROPs drive the pixel throughput, with a pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s.

The performance data shows the GPU operating well within its capabilities at 1080p, where frame rates exceed 300 FPS on Low settings. At 4K Ultra, the 57.4 FPS result indicates the card is nearly saturated, with the FP32 throughput of 34.10 TFLOPS becoming the binding constraint. Interestingly, the GPU outperforms the RTX 3090 in the nearest rival comparison by 0.5%, despite having the same GA102 chip but fewer CUDA cores enabled. This suggests that Pc Building Simulator's workload favors the 3080 Ti's specific clock behavior, with a boost clock of 1665 MHz. The 8 nm Samsung process node and 28,300 million transistors contribute to the card's 350 W TDP, which requires robust cooling and a 750 W suggested PSU.

# FAQ

Q: Does the game benefit from the GPU's ray tracing cores?

A: The measured FPS data does not include ray tracing-specific benchmarks for Pc Building Simulator. The GPU's 80 RT cores are available, but the game's settings presets (Low, Medium, High, Ultra) do not explicitly indicate ray tracing usage in the measured results.

# CPU Role

The Intel Core i5-12400F contributes 6 cores and 12 threads based on the Alder Lake architecture, with a base clock of 2.50 GHz and boost clock of 4.40 GHz. This 10 nm processor features 18 MB of shared L3 cache and 1.25 MB of L2 cache per core, providing 80 KB of L1 cache per core. In synthetic benchmarks, the CPU achieves a Cinebench R23 multi-core score of 16,518 and single-core score of 2,332, while Geekbench results show 9,138 multi-core and 2,221 single-core. These numbers place the CPU in the 77th percentile of all processors, with an average benchmark score of 19,221.

The closest rival, the Intel Core i7-8700K, scores 19,210 (0.1% lower), meaning the i5-12400F effectively matches an older flagship with two fewer cores and four fewer threads. This is attributable to the newer architecture's higher instructions per clock and the 4.40 GHz boost clock. In Pc Building Simulator, the CPU's role is to manage the simulation logic, component placement physics, and UI rendering, which are not as demanding as the 3D scene rendering handled by the GPU. The measured FPS data shows that the CPU can sustain frame rates above 350 FPS at 1080p Low, indicating it is not a limiting factor at standard resolutions. However, at 4K, the GPU becomes the primary constraint, as evidenced by the FPS scaling patterns. The 65 W TDP and dual-channel memory support (DDR4 and DDR5) make this a versatile pairing, though the PCIe Gen 5 lanes (20 on CPU) are not fully utilized by the RTX 3080 Ti's PCIe 4.0 x16 interface.
