Downfall

Resolution Scaling

The measured FPS data for Downfall with the Intel Core i5-12400F and NVIDIA GeForce RTX 5080 shows a predictable scaling pattern as resolution increases, but the magnitude of the drop reveals where the bottleneck lies. At 1080p Low, the combo produces 390.6 FPS, which falls to 302.4 FPS at 1440p Low and 189.7 FPS at 4K Low. That is a 22.6% drop from 1080p to 1440p and a 37.3% drop from 1440p to 4K. The scaling is steep, indicating that even at Low settings, the GPU is being pushed harder as pixel count rises.

At High settings, the pattern is similar but the absolute numbers are lower. The combo delivers 285.5 FPS at 1080p, 203.3 FPS at 1440p, and 124.1 FPS at 4K. The percentage drop from 1080p to 1440p is 28.8%, and from 1440p to 4K it is 39.0%. The slightly larger percentage drops at High settings compared to Low suggest that the GPU is becoming more of a limiting factor as visual complexity increases.

Ultra settings show the most dramatic scaling. At 1080p Ultra, the combo hits 179.6 FPS, which drops to 125.7 FPS at 1440p Ultra and 81.1 FPS at 4K Ultra. The 1440p to 4K drop is 35.5%. The data indicates that at 1080p and 1440p, the CPU is capable of feeding the GPU well enough that the RTX 5080 can stretch its legs, but at 4K Ultra, the GPU is clearly the dominant constraint. The fact that 4K Ultra still produces 81.1 FPS shows the GPU has substantial headroom, but the scaling curve is consistent with a GPU-bound scenario at that resolution.

Settings Recommendations

The measured rows provide a clear hierarchy for settings optimization. At 1080p, the Low preset yields 390.6 FPS, Medium produces 346.3 FPS, High delivers 285.5 FPS, and Ultra drops to 179.6 FPS. The jump from High to Ultra costs 105.9 FPS, which is a 37.1% reduction for what is typically a marginal visual improvement. The data suggests that High is the sweet spot at 1080p, balancing the 285.5 FPS result against the diminishing returns of Ultra.

At 1440p, the pattern repeats. Low produces 302.4 FPS, Medium hits 245.9 FPS, High delivers 203.3 FPS, and Ultra falls to 125.7 FPS. The drop from High to Ultra is 77.6 FPS, or 38.2%. Given that 1440p High still exceeds 200 FPS, this preset is the recommended choice for high-refresh-rate monitors. Medium is also viable if the user prefers extra headroom, as 245.9 FPS is still exceptionally smooth.

At 4K, the choices become more consequential. Low yields 189.7 FPS, Medium delivers 156.4 FPS, High produces 124.1 FPS, and Ultra drops to 81.1 FPS. The data shows that 4K Ultra is the only preset that dips below 100 FPS, but 81.1 FPS is still playable for most genres. For a horror game where atmosphere matters, High at 124.1 FPS offers a strong balance between visual fidelity and frame rate. Medium at 156.4 FPS is the safer pick for maintaining high refresh rates, while Low at 189.7 FPS is available for competitive play. The measured data indicates that High is the best overall experience at 4K, as it keeps the frame rate above 120 FPS while preserving most of the visual quality.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor from the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB of shared L3 cache and 1.25 MB L2 cache per core are relevant for game workloads that benefit from fast data access. The CPU's benchmark scores show a single-thread result of 909 in 3dmark and 3481 in passmark_single_thread, which are solid figures for gaming. The multi-threaded performance is also respectable, with a cinebench_r23_multicore score of 16518 and a geekbench_multicore score of 9138.

In Downfall, the CPU's role is most evident at lower resolutions where the GPU is not the bottleneck. At 1080p Low, the combo produces 390.6 FPS, which is an extreme frame rate that requires strong per-core performance to feed the RTX 5080. The 3dmark_2_threads score of 1699 and the 3dmark_single_thread score of 909 indicate that the CPU has the single-threaded horsepower to keep up with high-FPS scenarios. The passmark_physics score of 1202 is less impressive, but Downfall's horror genre likely does not stress physics calculations as heavily as other games.

The CPU's percentile rank of 77 against all CPUs places it above average, and its nearest rival, the Intel Core i7-8700K, has an average score of 19210 with a deltaPct of 0.1, meaning the i5-12400F is essentially on par with that older flagship. This parity is notable because the i7-8700K has higher clocks but fewer modern architectural advantages. The data suggests that the i5-12400F is not the limiting component in this combo, even at 1080p where frame rates exceed 300 FPS. The CPU's 6 cores and 12 threads are sufficient for Downfall's threading model, and the boost clock of 4.40 GHz provides the responsiveness needed for high-FPS gameplay.

How This Combo Ranks

The combo of the Intel Core i5-12400F and NVIDIA GeForce RTX 5080 ranks 83rd out of 1741 tested combinations in Downfall. This places it in the top 4.8% of all combos, which is an exceptionally strong result. The high rank is primarily driven by the GPU's performance, as the RTX 5080 sits in the 89th percentile of all GPUs with an average benchmark score of 59188. The GPU's nearest rivals include the Intel Arc A570M with a deltaPct of 1.6, meaning the RTX 5080 is 1.6% faster, and the AMD Radeon Pro W5500X with a deltaPct of 2.6, indicating the RTX 5080 leads by 2.6%.

The rank of 83 out of 1741 is notable because it shows that this specific pairing is well-balanced for Downfall. The CPU's 77th percentile ranking is lower than the GPU's 89th percentile, which suggests that the CPU could be a minor bottleneck in some scenarios, but the overall combo still performs in the top 5% of all tested systems. The fact that the combo achieves 390.6 FPS at 1080p Low and 302.4 FPS at 1440p Low confirms that the pairing is capable of extreme frame rates that most systems cannot reach. The rank also benefits from the game's release date in 2016, as older games tend to be less demanding and allow high-end modern hardware to dominate the rankings.

GPU Role

The NVIDIA GeForce RTX 5080 is the primary driver of this combo's performance. With 16 GB of GDDR7 memory on a 256-bit bus, the GPU offers 960.0 GB/s of memory bandwidth, which is critical for high-resolution textures in Downfall. The GPU's boost clock of 2617 MHz and base clock of 2295 MHz provide the raw compute power, while its 10752 shading units and 336 tensor cores handle the game's rendering and any RT effects. The RTX 5080's fp32 performance of 56.28 TFLOPS is substantial, and its passmark_g3d score of 36565 places it in the 89th percentile of all GPUs.

The GPU's role is most apparent at 4K Ultra, where the combo produces 81.1 FPS. This is the lowest measured result, and it reflects the GPU being fully utilized. The memory bandwidth of 960.0 GB/s is sufficient for 4K textures, and the 16 GB VRAM capacity ensures that no texture streaming bottlenecks occur. The GPU's passmark_directx_12 score of 151 is lower than some rivals, but the game's engine likely uses DirectX 11 or earlier, given its 2016 release date. The GPU's nearest rivals in terms of average benchmark score include the Intel Arc A580 with a deltaPct of 2.5, meaning the RTX 5080 is 2.5% faster, and the Intel Arc Pro A60 with a deltaPct of -1.9, indicating the RTX 5080 trails that GPU by 1.9% in synthetic benchmarks.

In Downfall specifically, the GPU demonstrates its strength by maintaining high frame rates across all settings. Even at 4K High, the combo delivers 124.1 FPS, which is well above the 60 FPS target most games aim for. The GPU's pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are more than adequate for the game's visual demands. The data shows that the RTX 5080 is the clear performance leader in this pairing, and its capabilities are not fully taxed until 4K Ultra is selected.
