Downfall

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 3060 Ti produces a highly capable 1080p and 1440p gaming system for Downfall, though its performance curve reveals a clear hierarchy between settings presets. The data shows that the Medium preset delivers the most balanced experience, offering a substantial frame rate jump over High while avoiding the severe fidelity cuts of Low. At 1080p Medium, the combo hits 155.9 FPS average, which is a 23% improvement over High’s 126.4 FPS. This is the sweet spot for players with high-refresh monitors, as it provides enough headroom to maintain smooth gameplay. The Ultra preset, while visually demanding, drops the average to 82.1 FPS at 1080p—still playable but not ideal for competitive or fast-paced horror sequences where reaction time matters. At 1440p, Medium remains the strongest choice, with 112.8 FPS average, keeping the experience fluid. For 4K, the situation changes; Medium’s 71.1 FPS is the best compromise, as High drops to 57.2 FPS and Ultra falls to an unplayable 35.5 FPS. Low settings are not recommended for any resolution beyond 4K, as they sacrifice too much visual immersion for a genre that relies on atmosphere.

Settings Recommendations

The benchmark results clearly indicate that the Medium preset is the optimal configuration for this hardware combination across all tested resolutions. At 1080p, Medium yields 155.9 FPS, which is not only 23% faster than High but also 51% faster than Ultra, making it the most efficient use of the GPU’s resources. The jump from Medium to Low at 1080p is 35.4 FPS (from 155.9 to 191.3), but that gain comes at the cost of significant visual detail that is crucial for the horror genre’s environmental storytelling. At 1440p, the Medium preset’s 112.8 FPS average keeps the experience above the 100 FPS threshold, while High trails at 94.6 FPS and Ultra drops to 54.4 FPS. For 4K, Medium’s 71.1 FPS is the only preset that maintains a playable frame rate above 60 FPS, making it the clear choice for UHD displays. High at 4K produces 57.2 FPS, which is borderline for smooth gameplay, and Ultra at 35.5 FPS is effectively a slideshow. Low settings are only advisable for 4K users who prioritize frame rate over everything else, but the 83.9 FPS result at that resolution still falls short of what Medium offers at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 3060 Ti is the primary driver of frame rate scaling in Downfall, and the data reflects its 8 GB GDDR6 memory and 448.0 GB/s bandwidth handling the game’s texture loads effectively. The GPU’s boost clock of 1665 MHz and its 4864 shading units provide the raw compute power needed for the horror game’s lighting and particle effects. At 1080p, the GPU is clearly not the bottleneck, as evidenced by the 191.3 FPS average on Low settings—this indicates the CPU is keeping up with the GPU’s output. However, the GPU’s role becomes more pronounced as resolution increases. The 4K results show a dramatic performance cliff between Medium (71.1 FPS) and Ultra (35.5 FPS), a 50% drop that suggests the 8 GB VRAM buffer is being saturated by Ultra’s higher-resolution textures. The RTX 3060 Ti’s 80 ROPs and 152 TMUs are sufficient for 1440p Medium, where it achieves 112.8 FPS, but the pixel rate of 133.2 GPixel/s starts to struggle at 4K Ultra. The GPU’s 16.20 TFLOPS FP32 performance is well-matched for this game, yet the Ultra preset at 4K pushes it beyond its comfort zone. This is a GPU that excels at 1080p and 1440p, but 4K requires careful settings management.

CPU Role

The Intel Core i5-9400, with its 6 cores and 6 threads, provides adequate processing power for Downfall, though it is not the star of the show. The CPU’s base clock of 2.90 GHz and boost clock of 4.10 GHz are sufficient to feed the RTX 3060 Ti at lower resolutions, as shown by the 191.3 FPS average at 1080p Low. This indicates the CPU is not bottlenecking the GPU at 1080p, since the frame rate scales appropriately with settings changes. The 9 MB shared L3 cache helps with the game’s asset streaming, and the 42.7 GB/s memory bandwidth is adequate for a title from 2016. However, the CPU’s limitations become apparent when comparing across resolutions. The 1080p to 1440p scaling at High settings shows a 25% frame rate drop (from 126.4 to 94.6 FPS), which is expected. But the CPU’s 6-thread limitation means it cannot fully leverage the GPU’s potential in CPU-bound scenarios. The data suggests that at 1080p Low, the CPU is the limiting factor, as the GPU could likely push higher frame rates if the CPU were faster. The Cinebench R23 multicore score of 7969 places this CPU at the 50th percentile, indicating it is mid-pack. For a horror game that relies on sudden AI-driven events, the 6-thread count is adequate, but it does not provide the headroom for background tasks that a higher-thread processor would offer.

How This Combo Ranks

This specific combination of the Intel Core i5-9400 and NVIDIA GeForce RTX 3060 Ti ranks 1219 out of 1741 tested combos in Downfall, placing it in the 70th percentile of all configurations. This ranking is slightly lower than what the GPU alone would suggest, given that the RTX 3060 Ti sits at the 69th percentile of all GPUs. The disparity between the GPU’s standalone percentile and the combo’s ranking indicates that the CPU is holding back the system somewhat. The CPU’s nearest rival, the Intel Core i3-10305, scores 2300 in average benchmarks versus the i5-9400’s 2305, a negligible 0.2% difference. This means the i5-9400 is performing exactly as expected for its class. The combo’s rank is also affected by the fact that many of the 1741 tested combos include newer CPUs with higher core counts. In practice, this rank means the system will outperform roughly 70% of tested configurations, but it will struggle against combos with modern 8-core processors paired with similar GPUs. The data shows that the RTX 3060 Ti has headroom that the i5-9400 cannot fully utilize, particularly in scenarios where the CPU becomes the bottleneck.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a predictable pattern that points to the GPU as the primary constraint at higher resolutions. At Medium settings, the FPS drops from 155.9 at 1080p to 112.8 at 1440p (a 28% decrease) and then to 71.1 at 4K (a 54% decrease from 1440p). This scaling is consistent with a GPU-bound scenario, where the rendering load increases with pixel count. At High settings, the drop from 1080p to 1440p is 25% (from 126.4 to 94.6 FPS), and the drop to 4K is 40% (from 94.6 to 57.2 FPS). The Low settings show the most dramatic scaling, with 1080p at 191.3 FPS, 1440p at 138.8 FPS (a 27% drop), and 4K at 83.9 FPS (a 40% drop). The fact that the 1080p to 1440p scaling is consistent across all settings (around 25-28%) indicates the CPU is not the bottleneck at these resolutions. However, the 4K drops are more severe, suggesting the GPU’s memory bandwidth and pixel throughput are being taxed. The 448.0 GB/s bandwidth is a limiting factor at 4K, as the game’s textures require more data transfer. This analysis indicates that for 1080p and 1440p, the system is well-balanced, but 4K requires dropping to Medium settings to maintain playability.

Measured FPS Breakdown

The complete measured FPS data for this combo provides a detailed picture of performance across all settings and resolutions. At 1080p, the averages are: 82.1 FPS on Ultra, 126.4 FPS on High, 155.9 FPS on Medium, and 191.3 FPS on Low. This represents a 133% spread between the lowest and highest settings, indicating the GPU has significant headroom at this resolution. The 1440p results show: 54.4 FPS on Ultra, 94.6 FPS on High, 112.8 FPS on Medium, and 138.8 FPS on Low. The spread narrows to 155%, but Ultra remains below the 60 FPS threshold. At 4K, the averages are: 35.5 FPS on Ultra, 57.2 FPS on High, 71.1 FPS on Medium, and 83.9 FPS on Low. Here, only Medium and Low achieve playable frame rates above 60 FPS. The data shows that the step from High to Ultra at any resolution causes a significant drop: at 1080p, it’s a 35% decrease (from 126.4 to 82.1); at 1440p, it’s a 43% decrease (from 94.6 to 54.4); and at 4K, it’s a 38% decrease (from 57.2 to 35.5). This consistent drop indicates that the Ultra preset introduces effects that disproportionately tax the GPU. Conversely, the step from Medium to High is more moderate: 19% at 1080p (from 155.9 to 126.4), 16% at 1440p (from 112.8 to 94.6), and 20% at 4K (from 71.1 to 57.2). This makes Medium the most efficient setting, as it offers a 19-20% performance boost over High with a smaller visual fidelity loss than dropping to Low. The data supports a clear recommendation: use Medium for 1440p and 4K, and consider High for 1080p if visual quality is paramount.
