Downfall

Downfall is a 2016 horror title that, on this hardware pairing, delivers exceptionally high frame rates across all tested configurations. The AMD Ryzen 5 5500X3D and NVIDIA GeForce RTX 5090 D combination produces results that are far beyond what the game requires for smooth play, making the choice of settings a matter of balancing visual fidelity against already surplus performance. The data indicates that this combo is never bottlenecked by the GPU in a way that forces a compromise; instead, the CPU's strong single-threaded performance and the GPU's massive memory bandwidth create a system capable of handling the game with ease.

Settings Recommendations

The measured FPS rows show a clear hierarchy across the four settings presets. At 4K, the Ultra preset averages 90 FPS, which is the lowest recorded figure for this combo but still comfortably within the bounds of smooth gameplay for a horror title where atmospheric tension often benefits from consistent pacing. However, the jump to High at 4K yields 144 FPS, a 60% improvement over Ultra, while likely retaining most of the visually important effects that a game from 2016 can offer. The data suggests that High is the optimal choice for 4K, as it provides a substantial frame rate buffer that prevents any potential dips from becoming noticeable.

Moving to the lower presets at 4K reveals diminishing returns for the loss in visual quality. Medium produces 175 FPS, while Low reaches 214 FPS. These numbers are impressive, but the difference between High and Medium (31 FPS) is less critical than the difference between Ultra and High (54 FPS). Given that the game is a horror title where shadows and lighting are crucial for atmosphere, sacrificing the High preset's visual features for a 31 FPS gain at Medium is not a practical trade-off. The Low preset at 327 FPS at 1080p is the absolute maximum performance, but it is unnecessary.

At 1440p, the pattern shifts slightly. High averages 231 FPS, while Medium is at 272 FPS, a difference of 41 FPS. The Ultra preset at 1440p hits 144 FPS, matching the High preset's 4K performance. This indicates that the GPU has enough headroom at 1440p to make even Ultra a viable option, but High remains the sweet spot because it nearly doubles the refresh rate of most high-end monitors while still delivering a complete visual package. The Low preset at 1440p produces 292 FPS, which is marginal over the Medium result.

At 1080p, the data shows that the CPU begins to play a more significant role. High averages 284 FPS, Medium is at 305 FPS, and Low reaches 327 FPS. The difference between Low and High is 43 FPS, which is smaller than the 70 FPS gap seen between the same settings at 4K. This compression of frame rates at lower resolutions suggests that the CPU is starting to limit the maximum output, as the GPU has more than enough power to render frames quickly. For the best experience at 1080p, the High preset is again the recommended choice, as it offers the full visual experience while still delivering 284 FPS, which far exceeds any display's refresh rate capabilities.

The general recommendation across all resolutions is to use the High preset. It provides the best balance between the measured frame rates and the visual quality expected from a horror game. The Ultra preset should only be considered if a user prioritizes absolute image quality over the 54-86 FPS drop it causes, but the data shows that High is the practical default for a smooth and immersive experience.

How This Combo Ranks

The combination of the AMD Ryzen 5 5500X3D and NVIDIA GeForce RTX 5090 D ranks 126th out of 2928 tested combos in Downfall. This places it in the top 4.3% of all configurations, which is a strong result for a pairing that includes a 2025 CPU and a 2025 GPU. The rank indicates that this setup is significantly faster than the vast majority of other hardware combinations tested for this specific game.

The CPU's individual performance contributes to this high rank. The Ryzen 5 5500X3D has an average benchmark score of 37018, placing it in the 85th percentile of all CPUs. Its nearest rivals in the benchmark database are the AMD Ryzen 5 5600F, which scores 36945 (a 0.2% difference), and the Intel Core Ultra 5 225, which scores 36938 (also a 0.2% difference). This shows that the 5500X3D is positioned right at the top of its performance class, trading blows with other mid-range processors.

The GPU's role in this rank is even more pronounced. The RTX 5090 D has an average benchmark score of 77712, placing it in the 92nd percentile of all GPUs. Its nearest rivals are notably different in class, such as the AMD Radeon RX 6850M XT with a score of 78940 (-1.6% delta) and the NVIDIA Tesla P100 PCIe 16 GB with a score of 79605 (-2.4% delta). This indicates that the RTX 5090 D is a top-tier consumer card, and its high score is the primary driver behind the combo's strong rank in this game.

The rank of 126 out of 2928 is impressive, but it is not a top-10 placement. This suggests that while the hardware is powerful, other factors, such as the game's engine limitations or CPU bottlenecks at lower resolutions, prevent this combo from reaching the absolute peak of the rankings. The data implies that the 5500X3D, despite being a capable processor, may hold back the RTX 5090 D in a game like Downfall, which might not be perfectly optimized for multi-threaded workloads.

GPU Role

The NVIDIA GeForce RTX 5090 D is a monster of a graphics card, and its specifications directly explain the high frame rates measured in Downfall. It features 32 GB of GDDR7 memory on a 512-bit bus, delivering a bandwidth of 1.79 TB/s. This massive memory subsystem is overkill for a 2016 game, but it ensures that there are no memory bandwidth bottlenecks even at 4K with high-resolution textures. The GPU's 21760 shading units and 680 TMUs provide immense pixel and texture throughput, which is why the game can run at 202 FPS on Ultra at 1080p.

The card's clock speeds, with a base of 2017 MHz and a boost of 2407 MHz, are high for a GPU of this size. The measured FPS data shows that the GPU is capable of pushing the game to 327 FPS at 1080p on Low settings, which is a clear demonstration of its raw compute power. The RTX 5090 D's 104.8 TFLOPS of FP32 performance is more than enough to handle the DirectX 12 rendering path that Downfall supports.

In the context of Downfall, the GPU is the dominant factor in determining performance at higher resolutions. The data shows that at 4K, the frame rate scales directly with the settings preset, from 90 FPS at Ultra to 214 FPS at Low. This scaling indicates that the GPU is the limiting component at 4K, as lowering the graphical load directly translates to higher frame rates. The 32 GB of VRAM is never a concern, as the game's assets are unlikely to exceed even a fraction of that capacity, but the bandwidth and compute power are what drive the performance.

The GPU's benchmark scores corroborate its in-game performance. Its Passmark G3D score of 44065 and 3DMark Steel Nomad DX12 score of 14326 are indicative of a top-tier part. The Geekbench OpenCL score of 310674 and Vulkan score of 376915 further confirm its compute capabilities. While these synthetic benchmarks do not directly translate to game FPS, they align with the measured results that show the RTX 5090 D providing well over 144 FPS at 1440p on High settings.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how the combo performs across different resolutions and settings. At 3840x2160 (4K), the Ultra preset averages 90 FPS, which is the lowest recorded. The High preset at 4K jumps to 144 FPS, a significant 54 FPS improvement. Medium at 4K averages 175 FPS with a minimum of 149 FPS and a maximum of 202 FPS, showing a tight frame time distribution. Low at 4K reaches 214 FPS, which is the highest 4K result.

Moving to 2560x1440 (1440p), the performance increases across the board. Ultra averages 144 FPS, which is exactly the same as High at 4K, highlighting the resolution scaling. High at 1440p averages 231 FPS, a 60% improvement over the 4K High result. Medium at 1440p averages 272 FPS with a minimum of 231 FPS and a maximum of 313 FPS, demonstrating very stable performance. Low at 1440p averages 292 FPS, which is the second-highest result in this resolution.

At 1920x1080 (1080p), the frame rates are at their peak. Ultra averages 202 FPS, which is higher than the 4K High result. High at 1080p averages 284 FPS, a substantial number for a visually rich preset. Medium at 1080p averages 305 FPS with a minimum of 259 FPS and a maximum of 350 FPS, showing that the combo can push beyond 300 FPS consistently. Low at 1080p averages 327 FPS, which is the maximum recorded average across all tests.

The data reveals a pattern: the gap between settings narrows as resolution decreases. At 4K, the difference between Ultra and Low is 124 FPS. At 1440p, the difference is 148 FPS. At 1080p, the difference is 125 FPS. This non-linear scaling suggests that at 1080p, the CPU is becoming a limiting factor, preventing the GPU from fully flexing its muscles and creating a larger gap between settings.

Resolution Scaling

The FPS drop from 1080p to 4K provides insight into which component is the bottleneck. At 1080p High, the combo averages 284 FPS. At 1440p High, it drops to 231 FPS, a decrease of 53 FPS (18.7%). At 4K High, it drops to 144 FPS, a further decrease of 87 FPS (37.7%). This scaling pattern is typical of a GPU-bound scenario, where increasing the pixel count directly impacts the render workload.

However, the scaling is not perfectly linear with pixel count. The pixel count from 1080p to 4K quadruples, but the frame rate only drops by 49% (from 284 to 144). This indicates that the GPU is not the sole limiting factor at 1080p. If it were, the 4K frame rate would be closer to 71 FPS (284/4). Instead, it is 144 FPS, suggesting that at 1080p, the CPU is holding back the GPU from reaching its full potential, and the GPU has headroom that is only utilized at higher resolutions.

Comparing Low settings across resolutions reinforces this. At 1080p Low, the combo hits 327 FPS. At 1440p Low, it drops to 292 FPS, a decrease of 35 FPS. At 4K Low, it drops to 214 FPS, a further decrease of 78 FPS. The drop from 1080p to 1440p is relatively small (10.7%), but the drop from 1440p to 4K is steeper (26.7%). This suggests that at 1080p Low, the CPU is a hard limit, capping performance around 327 FPS. As resolution increases, the GPU becomes more engaged, and the frame rate scales more predictably with pixel count.

The data indicates that for this game, the Ryzen 5 5500X3D is the limiting factor at 1080p, preventing the RTX 5090 D from exceeding roughly 330 FPS. At 4K, the GPU takes over as the primary bottleneck, and the frame rate scales more predictably with the settings preset. This is a classic sign of a high-end GPU paired with a mid-range CPU, where the CPU's single-threaded performance caps the maximum frame rate at lower resolutions.

CPU Role

The AMD Ryzen 5 5500X3D is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.00 GHz and a boost clock of 4.00 GHz, with a 96 MB shared L3 cache. This large cache is a key feature of the X3D series, and it helps with gaming performance by reducing memory latency. The CPU's Passmark single-thread score is 2941, and its multithread score is 20363, placing it in the 85th percentile of all CPUs.

In Downfall, the CPU's role is most evident at 1080p. The fact that the frame rates at 1080p High (284 FPS) and 1080p Low (327 FPS) are not as far apart as they are at 4K (144 vs 214 FPS) shows that the CPU is hitting a performance ceiling. The game, being from 2016, likely uses a single primary game thread, and the 5500X3D's boost clock of 4.00 GHz is sufficient to drive high frame rates, but it cannot keep up with the RTX 5090 D's raw rendering speed.

The CPU's benchmark scores relative to its rivals clarify its position. The Ryzen 5 5500X3D's average score of 37018 is nearly identical to the AMD Ryzen 5 5600F (36945) and the Intel Core Ultra 5 225 (36938), with deltas of 0.2%. This means that in synthetic workloads, the 5500X3D is effectively tied with these other mid-range parts. The 96 MB L3 cache, however, provides a distinct advantage in gaming, which is why the combo is able to achieve such high scores in Downfall despite the CPU's modest clock speeds.

The CPU's 105W TDP and support for DDR4 memory (with a dual-channel bandwidth of 51.2 GB/s) are adequate for this game. The data suggests that the CPU is not a weak link in a traditional sense, but it is the limiting factor when the GPU is not fully loaded. At 4K, the CPU's workload is relatively lighter because the GPU is busy rendering more pixels, allowing the frame rate to be dictated by the GPU's performance. At 1080p, the CPU must feed the GPU with draw calls, and its 4.00 GHz boost clock is the ceiling for this task.

The Passmark physics score of 2282 and the integer math score of 60033 provide additional context. These scores indicate solid computational performance, but the single-thread score of 2941 is the most relevant for a game like Downfall. The data shows that the CPU's single-thread performance is sufficient to deliver over 300 FPS at 1080p Medium, but the scaling to 4K is smooth, confirming that the CPU is not a bottleneck at higher resolutions. For users with high-refresh-rate 1080p monitors, this CPU may be the limiting factor, but for 1440p or 4K displays, the RTX 5090 D will be the primary driver of performance.
