Downfall

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 5090 is an overwhelmingly powerful combination for Downfall, delivering frame rates that far exceed the 60 FPS playability threshold at every resolution and preset tested. Benchmark data indicates this combo is ranked 51st out of 3716 tested configurations, placing it in the top 1.4% of systems. Across all three resolutions, the system maintains average frame rates well above 100 FPS even at the most demanding settings, making it capable of driving high-refresh-rate displays without compromise.

Best Settings per Resolution

At 1920x1080, the system achieves its highest performance ceiling. The most demanding preset, Ultra, runs at an average of 192.2 FPS. This is the recommended setting for this resolution, as it provides the full visual experience while still delivering nearly triple the 60 FPS threshold. Lower settings yield even higher frame rates — Low averages 456.1 FPS, Medium averages 372.6 FPS, and High averages 306.2 FPS — but the Ultra preset's 192.2 FPS average is already so far above the playability threshold that there is no practical reason to sacrifice visual quality.

At 2560x1440, the Ultra preset again emerges as the best choice, maintaining an average of 139.6 FPS. This is comfortably above the 60 FPS threshold, leaving substantial headroom for demanding scenes. The scaling from 1080p to 1440p shows a predictable performance cost: Ultra drops from 192.2 FPS to 139.6 FPS, a 27% reduction. However, even this reduced figure remains more than double the playability threshold. High settings at this resolution average 220.6 FPS, Medium averages 267 FPS, and Low averages 326.3 FPS, all of which are exceptionally high.

At 3840x2160, the Ultra preset still holds at 87.5 FPS average, which clears the 60 FPS threshold with a 46% margin. This is the most demanding configuration tested, yet the system handles it without dropping below playable levels. High settings average 136 FPS, Medium averages 168.7 FPS, and Low averages 203.2 FPS. The verdict data confirms that all four settings — Low, Medium, High, and Ultra — are playable at 4K, with Ultra being the optimal choice for maximum fidelity while maintaining a smooth experience.

CPU and GPU Roles

The performance scaling across resolutions and presets reveals that the GPU is the primary bottleneck for this combination in Downfall. The CPU, with its 12 cores and 24 threads based on Zen 4 architecture, provides ample processing power that never becomes the limiting factor. The data shows a clear pattern: as resolution increases from 1080p to 4K, frame rates drop proportionally, which is characteristic of GPU-bound scenarios.

Examining the scaling between presets at each resolution provides further evidence. At 1920x1080, moving from Low to Ultra reduces average FPS from 456.1 to 192.2, a 58% decrease. At 2560x1440, the same preset transition drops from 326.3 to 139.6 FPS, a 57% decrease. At 3840x2160, the drop is from 203.2 to 87.5 FPS, a 57% decrease. This consistent proportional reduction across resolutions indicates that the GPU's workload scales uniformly with visual complexity, while the CPU maintains its ability to feed the graphics card.

The resolution scaling itself tells the same story. At Ultra settings, moving from 1080p to 1440p reduces FPS by 27%, and moving from 1440p to 4K reduces it by another 37%. These are substantial performance hits that align with the increased pixel count and shading demands placed on the GPU. The RTX 5090's 32 GB of GDDR7 memory and 512-bit bus provide 1.79 TB/s of bandwidth, which is sufficient to handle 4K textures without memory-related stutters. The CPU's role remains consistent throughout — it delivers high single-thread and multi-thread performance that never constrains the GPU, as evidenced by the smooth scaling curves.

Measured FPS Breakdown

At 1920x1080, the measured frame rates are exceptionally high across all presets. Low settings produce an average of 456.1 FPS, making this the fastest configuration in the entire dataset. Medium settings average 372.6 FPS, High settings average 306.2 FPS, and the most demanding Ultra preset still achieves 192.2 FPS. The gap between Low and Ultra represents a 263.9 FPS difference, demonstrating the significant impact of visual fidelity settings on this hardware.

At 2560x1440, the performance remains remarkably strong. Low settings average 326.3 FPS, Medium settings average 267 FPS, and High settings average 220.6 FPS. The Ultra preset drops to 139.6 FPS, which is still more than double the playability threshold. The progression from Low to Ultra shows a consistent degradation: each step up in quality costs roughly 60-80 FPS at this resolution. This pattern suggests that the GPU handles each preset tier with predictable efficiency.

At 3840x2160, the system continues to deliver playable performance across all settings. Low settings average 203.2 FPS, Medium settings average 168.7 FPS, and High settings average 136 FPS. The Ultra preset averages 87.5 FPS, which is the lowest figure recorded for this combination but remains comfortably above the 60 FPS threshold. The 4K Ultra result is particularly notable because it shows that even the most demanding configuration in this test does not push the system to its limits. The data shows no minimum or maximum FPS figures, only averages, but the consistent averages across multiple presets and resolutions indicate stable performance without severe frame-time spikes.

Similar Performance Alternatives

The CPU's nearest rivals, based on average benchmark scores, provide context for how the Ryzen 9 7900X performs relative to other processors. The AMD EPYC 7313P scores 53,206, which is 0.2% lower than the Ryzen 9 7900X's 53,288 average. The Intel Xeon Phi 7290 scores 53,469, a 0.3% advantage over the 7900X. The Intel Xeon 634 scores 52,974, trailing by 0.6%. The Intel Core i7-14700F scores 53,620, leading the 7900X by 0.6%. These deltas are all within 1% of each other, meaning a system with any of these CPUs would deliver nearly identical frame rates in Downfall when paired with the same GPU.

On the GPU side, the RTX 5090's nearest rivals show similarly tight clustering. The NVIDIA Tesla P100 PCIe 16 GB scores 79,605, which is 0.3% lower than the 5090's 79,842 average. The Tesla P100 PCIe 12 GB scores 79,396, trailing by 0.6%. The AMD Radeon RX 6850M XT scores 78,940, a 1.1% deficit. The AMD Radeon Pro Vega 64X scores 80,959, leading by 1.4%. These small deltas suggest that swapping the RTX 5090 for any of these alternatives would produce nearly identical performance in this game, with frame rate differences of only a few FPS at most. For practical purposes, any combination of the 7900X with one of these rival GPUs would maintain the same playability verdict across all resolutions and presets.

How This Combo Ranks

The combination of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 5090 ranks 51st out of 3716 tested combos in Downfall. This places the system in the 98.6th percentile of all configurations tested, meaning only 50 combinations performed better. Given that the dataset includes a wide range of hardware pairings, this top-1.4% ranking confirms that this is an elite-tier gaming system. The ranking reflects the cumulative strength of both components — the CPU's 91st percentile standing among all CPUs and the GPU's 92nd percentile among all GPUs combine to produce a system that handles this horror title with exceptional ease.

The high rank is consistent with the measured frame rates. At 4K Ultra, the system achieves 87.5 FPS average, which is 46% above the playability threshold. At 1440p Ultra, it nearly doubles the threshold at 139.6 FPS. At 1080p Ultra, it more than triples the threshold at 192.2 FPS. These results indicate that the combo not only meets but vastly exceeds the requirements for a smooth gaming experience. The rank of 51 also suggests that while there are a few faster combinations, they would deliver only marginal improvements over an already outstanding performance profile.

The Verdict

This PC can run Downfall at every resolution and preset configuration tested, with all results clearing the 60 FPS playability threshold. The verdict data confirms that all four settings — Low, Medium, High, and Ultra — are playable at every resolution from 1080p through 4K. At 1920x1080, the best settings are Ultra with an average of 192.2 FPS. At 2560x1440, Ultra is again the best choice, averaging 139.6 FPS. At 3840x2160, Ultra remains the recommended setting, averaging 87.5 FPS.

The system demonstrates remarkable headroom even in the most demanding scenario: 4K Ultra. The 87.5 FPS average provides a 27.5 FPS buffer above the 60 FPS threshold, which should absorb most frame-time spikes during intense gameplay moments. The horror genre often relies on sudden visual effects and dense lighting, but the RTX 5090's 104.8 TFLOPS of FP32 performance and 170 RT cores handle these demands without issue. The Ryzen 9 7900X's 64 MB of shared L3 cache and 5.6 GHz boost clock ensure that CPU-bound scenarios, such as AI-driven enemy behavior or complex physics interactions, do not introduce stutters.

For players targeting maximum visual fidelity, the Ultra preset at 4K is fully viable. For those with high-refresh-rate monitors, the 1440p Ultra configuration at 139.6 FPS pairs well with 144 Hz displays, while 1080p Ultra at 192.2 FPS suits 165 Hz or higher panels. The data shows no configuration that falls below the playability threshold, making this an uncompromising combination for Downfall. The only consideration is whether the visual quality differences between presets justify the frame rate trade-offs, but with all options playable, the choice comes down entirely to personal preference for fidelity versus raw frame rate.
