Downfall

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 3080 is a strong combination for Downfall, a 2016 horror title. Measured frame rates show the pair clearing the 60 FPS playable threshold at every resolution and preset tested except for 4K Ultra, where it averages 56 FPS. This analysis interprets the benchmark data, compares the hardware to its nearest rivals, and provides recommended settings for each resolution.

FAQ

Q: Can this combo run Downfall at 4K with max settings?

A: No. At 3840x2160 with Ultra settings, the average FPS is 56, which falls below the 60 FPS playable threshold. The highest playable setting at 4K is High, which averages 89 FPS.

Q: What is the best setting at 2560x1440?

A: Ultra, which averages 90 FPS. All four settings (Low, Medium, High, Ultra) are playable at this resolution, with Ultra being the most demanding that still stays above 60 FPS.

Q: How does the Ryzen 9 9900X3D compare to its nearest CPU rivals?

A: Its average benchmark score of 54762 is nearly identical to the Intel Core Ultra 5 245KF (55093, -0.6% delta) and slightly ahead of the Core Ultra 5 245K (54053, +1.3%), Xeon 6505P (53701, +2%), and Core i7-14700F (53620, +2.1%). These differences are small enough to have negligible impact on Downfall's frame rates.

Q: Is the RTX 3080 a bottleneck at any resolution?

A: The data shows strong resolution scaling, indicating GPU-bound behavior. At 1080p Low, the combo hits 299 FPS, dropping to 133 FPS at 4K Low. At Ultra, the drop from 125 FPS at 1080p to 56 FPS at 4K shows the GPU limiting performance as pixel count increases. The CPU is not the primary constraint at any resolution.

Q: What is the combo's overall ranking among tested systems?

A: It ranks 1057 out of 3716 tested combinations, placing it in the top 28% of all configurations tested for Downfall. This is a solid position, though not elite.

Q: Are there any settings that produce frame rates below 60?

A: Only 4K Ultra, with an average of 56 FPS. Every other tested setting at all resolutions exceeds 60 FPS, with the lowest being 4K High at 89 FPS.

Similar Performance Alternatives

The CPU and GPU each have a set of nearest rivals based on average benchmark scores. For the Ryzen 9 9900X3D, the closest alternatives are the Intel Core Ultra 5 245KF (55093, -0.6% delta), Core Ultra 5 245K (54053, +1.3%), Xeon 6505P (53701, +2%), and Core i7-14700F (53620, +2.1%). All of these are within 2.1% of the 9900X3D's score of 54762, meaning that swapping to any of them would produce nearly identical CPU performance in Downfall. Given that the game is not heavily multithreaded, the difference would be imperceptible in practice.

On the GPU side, the RTX 3080's average benchmark score of 23172 is matched closely by the NVIDIA P106-100 (23249, -0.3%), AMD Radeon Pro Vega 16 (23250, -0.3%), AMD Radeon RX 6600M (23273, -0.4%), and AMD Radeon R9 M290X (23276, -0.4%). These delta percentages are all under 0.5%, so any of these GPUs would deliver essentially the same frame rates as the RTX 3080 in Downfall. However, it is importantly some of these alternatives are not mainstream gaming cards (e.g., P106-100 is a mining-focused GPU, and R9 M290X is an older mobile part). Still, the benchmark data suggests that the RTX 3080's measured performance is representative of this performance tier.

For a builder considering a similar system, choosing any of these CPU or GPU alternatives would result in very close to the same FPS numbers reported here. The 60 FPS threshold would be crossed or missed at the same settings, making the decision largely irrelevant for this specific game.

CPU and GPU Roles

The measured FPS data across resolutions and presets reveals a clear pattern: the GPU is the dominant factor in determining performance, while the CPU provides ample headroom even at high frame rates. At 1920x1080, the combo achieves 299 FPS on Low, 245 FPS on Medium, 201 FPS on High, and 125 FPS on Ultra. Moving to 2560x1440, those numbers drop to 214, 175, 143, and 90 FPS respectively. At 3840x2160, they fall further to 133, 109, 89, and 56 FPS. The percentage drop from 1080p to 1440p is roughly 28-30% across all presets, and from 1440p to 4K it is another 38-40%. This consistent scaling indicates that the GPU is the primary limiter as resolution increases.

The CPU's role becomes more apparent at the lowest resolution and settings, where frame rates exceed 200 FPS. At 1080p Low, the system produces 299 FPS, which is close to the theoretical maximum for many displays. The Ryzen 9 9900X3D's strong single-thread performance (Cinebench R23 single-core score of 6739, Geekbench single-core of 3041) ensures that it can feed the GPU with enough draw calls to sustain such high output. Its multi-threaded scores (Cinebench R23 multi-core 47737, Geekbench multi-core 22884) are more than sufficient for a 2016 horror game that likely uses only a few cores. In short, the CPU will never bottleneck this GPU in Downfall, regardless of resolution or preset.

At 4K, the GPU is clearly the bottleneck. Even at Low settings, the average FPS is 133, which is still high, but the Ultra preset drops to 56 FPS because the RTX 3080 must process over eight million pixels per frame. The 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are adequate, but the raw shading power (29.77 TFLOPS FP32) is not enough to maintain 60 FPS at Ultra on a 4K display. The CPU's influence at this resolution is minimal; the frame rate is governed almost entirely by the GPU's rasterization throughput.

How This Combo Ranks

The combo holds a rank of 1057 out of 3716 tested combinations for Downfall. This places it in the 28th percentile, meaning it outperforms roughly 72% of all systems tested. Given that the RTX 3080 is a 2020 high-end card and the Ryzen 9 9900X3D is a 2025 flagship, the ranking reflects a well-above-average configuration for this title. However, it is not at the top; newer GPUs with higher memory bandwidth and more shading units would likely push higher frame rates at 4K Ultra. The data is measured (dataIsMeasured: true), so this rank is based on actual runs rather than estimates.

The practical implication is that this combo offers substantial headroom for Downfall. At 1080p and 1440p, it easily exceeds 60 FPS on the highest settings, and at 4K it is only the Ultra preset that dips below the threshold. For a horror game where smoothness and responsiveness matter, this system is more than capable.

The Verdict

Yes, this PC can run Downfall. The verdict by resolution is clear: at 3840x2160, the playable settings are High, Low, and Medium, with High being the best option at 89 FPS. At 2560x1440, all four settings are playable, with Ultra at 90 FPS. At 1920x1080, all settings are playable, with Ultra at 125 FPS. The only configuration that fails to hit 60 FPS is 4K Ultra, which averages 56 FPS. For anyone aiming for 4K, dropping to High will provide a comfortable margin above the playable threshold. For 1440p and 1080p users, the system can be pushed to maximum settings without concern.

The combination of a high-end 2025 CPU and a 2020 enthusiast GPU is more than enough for a 2016 horror title. The game's age means it does not leverage modern features like ray tracing or DLSS, but the raw performance of the RTX 3080 ensures high frame rates across the board.

Best Settings per Resolution

The most demanding preset that stays at or above 60 FPS at each resolution is as follows:

• 3840x2160: High — 89 FPS average. Ultra is not playable (56 FPS), so High is the highest setting that clears the threshold. Medium (109 FPS) and Low (133 FPS) are also playable, but High offers the best visual quality while remaining above 60.
• 2560x1440: Ultra — 90 FPS average. All settings are playable, and Ultra is the most demanding option that still exceeds 60 FPS. This gives the best image quality without sacrificing smoothness.
• 1920x1080: Ultra — 125 FPS average. The system has massive headroom at this resolution, so even the highest preset leaves plenty of room above the 60 FPS target.

These recommendations are based on average FPS. For Medium settings, the minimum FPS is also reported (92 at 4K, 149 at 1440p, 208 at 1080p), all well above 60. For other presets, minimums are not available, but the averages are high enough that dips below 60 are unlikely given the game's age and the hardware's capabilities.
