How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4080 SUPER achieves a rank of 280 out of 3,716 tested combos in Downfall. This places the pairing in the top 7.5% of all configurations tested, indicating that it delivers performance well above the median system. The rank reflects both the CPU's strong single-thread performance and the GPU's high fill rate, which together produce excellent frame rates across all tested settings.

Given that the CPU holds a 91st percentile ranking among all processors and the GPU holds an 86th percentile ranking, the combo rank of 280 is consistent with expectations. The gap between the individual component percentiles and the combo rank suggests that some other pairings—possibly with higher-tier GPUs or more gaming-optimized CPUs—manage to outperform this specific match-up. However, the 3,716 total combos mean that only 279 configurations deliver higher frame rates in this game, evidence of the strength of this pairing.

The data shows that the combo's ranking is not limited by the CPU, as its benchmark scores are competitive with rivals. Rather, the GPU's position at the 86th percentile, while strong, leaves room for higher-end cards to achieve better results. This suggests that in Downfall, the graphics card is the primary performance differentiator, and users seeking higher rankings would need to look at more powerful GPUs.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers exceptional frame rates across all settings. The Low preset achieves an average of 397 FPS, while Medium reaches 325 FPS with a minimum of 276 FPS and maximum of 374 FPS. High settings produce 267 FPS average, and Ultra drops to 167 FPS. These numbers indicate that at 1080p, even the Ultra preset provides frame rates well above the refresh rate of most monitors, making this resolution largely CPU-bound at lower settings.

Moving to 2560x1440, the performance remains strong but shows the expected scaling. Low settings yield 284 FPS average, Medium produces 232 FPS (minimum 197, maximum 267), High drops to 190 FPS, and Ultra settles at 119 FPS. The step from 1080p to 1440p reduces performance by approximately 28-29% across presets, a consistent decline that points to the GPU becoming more involved in rendering.

At 3840x2160 (4K), the frame rates become more demanding but remain very playable. Low settings deliver 177 FPS average, Medium achieves 144 FPS (minimum 123, maximum 166), High reaches 118 FPS, and Ultra drops to 74 FPS. The Ultra preset at 4K is the only configuration that falls below 100 FPS, though 74 FPS is still smooth for a horror game that emphasizes atmosphere over twitch gameplay.

The Medium preset at each resolution shows the tightest frame time consistency, with minimums that are roughly 15-17% below average and maximums that are 15-18% above. This suggests that Medium settings provide a balanced workload that avoids the extreme frame time spikes that can occur at Ultra or the potential CPU-bound inconsistencies at Low.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The performance scaling from 1080p to 4K reveals important information about which component limits performance in Downfall. At Low settings, the frame rate drops from 397 FPS at 1080p to 284 FPS at 1440p (a 28.5% reduction) and then to 177 FPS at 4K (a 37.7% further reduction from 1440p). This pattern indicates that at Low settings, the CPU is heavily involved, as the absolute frame rates are extremely high and the GPU is not the primary constraint.

At Medium settings, the scaling shows 325 FPS at 1080p, 232 FPS at 1440p (28.6% drop), and 144 FPS at 4K (37.9% drop). The consistency of these percentage drops across Low and Medium suggests that the workload distribution between CPU and GPU remains similar at these settings. However, at High settings, the progression is 267 FPS, 190 FPS (28.8% drop), and 118 FPS (37.9% drop), maintaining the same relative pattern.

The Ultra preset shows slightly different behavior: 167 FPS at 1080p, 119 FPS at 1440p (28.7% drop), and 74 FPS at 4K (37.8% drop). The near-identical percentage drops across all settings indicate that the limiting component does not change with resolution or quality level. This consistency suggests that the RTX 4080 SUPER is the primary bottleneck at all tested configurations, as frame rates scale predictably with pixel count rather than showing signs of CPU limitation at lower resolutions.

If the CPU were the limiting factor, we would expect to see smaller percentage drops from 1080p to 1440p at Low settings, where the GPU has less work to do. Instead, the uniform scaling indicates that the GPU's rendering capacity is the determining factor, with the 9900X3D providing enough headroom to avoid becoming a constraint even at the lowest settings.

Settings Recommendations

Based on the measured frame rates, the Medium preset offers the best balance of visual quality and performance consistency. At 4K, Medium delivers 144 FPS average with a minimum of 123 FPS, ensuring smooth gameplay even during intense horror sequences. The frame time data for Medium shows the most stable distribution among all presets, with minimums and maximums that stay within a reasonable range of the average.

For users with high-refresh-rate monitors (144 Hz or above), the High preset is the recommended choice. At 1440p, High produces 190 FPS average, providing enough headroom to maintain a stable 144 FPS experience. At 1080p, High reaches 267 FPS, which exceeds the refresh rate of most gaming displays. The jump from Medium to High costs roughly 18-20% performance but likely adds meaningful visual improvements in lighting and texture detail, which are important in a horror game's atmosphere.

The Ultra preset should be reserved for users who prioritize visual fidelity over frame rate. At 1440p, Ultra achieves 119 FPS, which remains above 60 FPS and is acceptable for most players. At 4K, Ultra drops to 74 FPS, which is still playable but may show occasional frame pacing issues in demanding scenes. Given that the Medium preset at 4K achieves nearly double the frame rate of Ultra, the visual difference between these presets would need to be substantial to justify the performance cost.

The Low preset, while delivering extremely high frame rates (397 FPS at 1080p), is not recommended for a horror game where atmosphere and visual immersion are critical. The data shows that Low settings sacrifice too much visual quality for frame rates that exceed the refresh rate of virtually all monitors. Users should start with Medium and adjust upward to High if they have refresh rate headroom, or downward to Medium if they experience frame time spikes at High settings.

Ultimately, the measured data supports Medium as the settings sweet spot for this combo in Downfall, with High as the choice for users with high-refresh displays who want enhanced visuals without sacrificing smoothness.
