Downfall

Resolution Scaling

The measured FPS data for Downfall with the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 5080 reveals a pronounced resolution scaling curve that shifts the bottleneck between CPU and GPU as pixel count rises. At 1920x1080 with Low settings, the combo delivers 386.4 FPS, which drops by 21.2% to 304.3 FPS at 2560x1440, and then falls another 37.6% to 189.8 FPS at 3840x2160. This scaling pattern indicates that at 1080p and even 1440p Low, the system is heavily CPU-limited — the Ryzen 9 5900X's 12 cores and 24 threads are sufficient to feed the RTX 5080 at these lower resolutions, and the frame rates are so high that the GPU is not the primary constraint.

Moving to High settings, the scaling changes character. At 1080p High, the combo produces 284.1 FPS. Dropping to 1440p High yields 200.3 FPS, a 29.5% reduction, and 4K High comes in at 125.6 FPS, another 37.3% reduction from 1440p. The percentage drops between 1080p and 1440p are larger at High settings than at Low settings, suggesting that the increased shading workload is beginning to engage the GPU more meaningfully even at mid-range resolutions. However, the RTX 5080's 56.28 TFLOPS FP32 compute and 960.0 GB/s memory bandwidth still deliver triple-digit frame rates at 4K High, indicating the GPU has substantial headroom for this horror title.

Ultra settings tell the most revealing story about the limiting component. At 1080p Ultra, the combo hits 180.3 FPS. At 1440p Ultra, it drops to 128.9 FPS (a 28.5% reduction), and at 4K Ultra, it falls to 77.8 FPS (a 39.6% reduction from 1440p). The consistent 28-40% reductions across each resolution step at Ultra suggest a more balanced workload, where both CPU and GPU are contributing to the performance envelope. The fact that 4K Ultra still maintains nearly 78 FPS average — comfortably above common 60 FPS display refresh thresholds — indicates that this combination can handle the game's maximum visual fidelity even at the highest resolution tested.

Settings Recommendations

Examining the measured rows, the sweet spot for this hardware combination depends heavily on the target resolution. At 1920x1080, every settings level produces frame rates above 180 FPS, with Low peaking at 386.4 FPS and Medium at 348.9 FPS. For players with high-refresh-rate displays, Medium settings at 1080p offer the best balance: the 348.9 FPS average is 22.7% higher than High's 284.1 FPS, and the visual upgrade from Low is substantial enough to justify the frame rate trade-off. Ultra at 1080p still delivers 180.3 FPS, which is playable, but the jump from Medium to Ultra costs 48.3% of the frame rate for what is likely a marginal visual improvement in a horror title where motion clarity matters more than texture fidelity.

At 2560x1440, the data points toward High or Medium as the optimal presets. Medium produces 248.7 FPS, while High delivers 200.3 FPS — both well above 144 Hz refresh rate thresholds. Ultra at 1440p drops to 128.9 FPS, which is still playable but represents a 35.5% reduction from High. The recommendation here is High settings, as the 200.3 FPS average leaves enough headroom for demanding scenes while providing the enhanced lighting and shadow quality that horror games rely on for atmosphere. Low at 1440p, at 304.3 FPS, is excessively high for any current display technology and sacrifices too much visual fidelity.

At 3840x2160, the choice narrows considerably. Ultra produces 77.8 FPS, which is playable on 60 Hz displays but marginal for 120 Hz panels. High settings at 4K deliver 125.6 FPS, a 61.4% improvement over Ultra, and this is the recommended preset for 4K gaming with this combo. Medium at 4K reaches 155.9 FPS, which exceeds most 4K display refresh rates, but the jump from High to Medium only gains 24.1% more frame rate while reducing visual quality. The data supports High as the best experience-per-measured-row choice at 4K, with Medium serving as a fallback for those prioritizing maximum frame rate.

GPU Role

The NVIDIA GeForce RTX 5080's specifications align closely with the measured performance in Downfall. The GPU features 16 GB of GDDR7 memory on a 256-bit bus, yielding 960.0 GB/s of memory bandwidth. In a horror game like Downfall, which typically involves large texture sets and shadow-heavy environments, this bandwidth is sufficient to avoid memory-related stutters even at 4K Ultra, where the 77.8 FPS average remains consistent with the scaling pattern rather than collapsing due to VRAM exhaustion. The 16 GB capacity provides ample headroom for this title, which was released in 2016 and does not demand the same memory footprint as modern AAA releases.

Clock speeds play a significant role in the observed scaling. The GPU's base clock of 2295 MHz boosts to 2617 MHz, and with 10752 shading units, the RTX 5080 achieves 56.28 TFLOPS of FP32 compute. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are directly relevant to Downfall's fill-rate requirements, particularly at higher resolutions where pixel throughput becomes more critical. The 84 RT cores and 336 tensor cores are less relevant for this title given its 2016 release date, which means the GPU's traditional rasterization performance — as measured by the DirectX 11 and DirectX 12 benchmark scores of 324 and 151, respectively — is what drives the frame rates seen in the measured data.

The GPU's benchmark percentile of 89 versus all GPUs, with an average benchmark score of 59188, places it in the upper tier of tested hardware. Its nearest rivals in the benchmark database include the Intel Arc A570M at 58239 (1.6% lower), the Intel Arc Pro A60 at 60326 (1.9% higher), and the Intel Arc A580 at 57756 (2.5% lower). These deltas are small, suggesting that the RTX 5080's performance class is well-established, and the measured Downfall results reflect a GPU that is not being artificially constrained by its memory subsystem or clock behavior.

Measured FPS Breakdown

At 1920x1080, the full settings sweep shows a clear hierarchy. Low settings produce 386.4 FPS, Medium 348.9 FPS, High 284.1 FPS, and Ultra 180.3 FPS. The gap between Low and Medium is 37.5 FPS (9.7%), between Medium and High is 64.8 FPS (18.6%), and between High and Ultra is 103.8 FPS (36.5%). This widening delta as settings increase indicates that each step up in quality level imposes a progressively larger computational cost, with Ultra being the most demanding step by a significant margin.

At 2560x1440, the measured values are 304.3 FPS for Low, 248.7 FPS for Medium, 200.3 FPS for High, and 128.9 FPS for Ultra. The relative gaps remain similar to 1080p, with the Low-to-Medium gap at 55.6 FPS (18.3%), Medium-to-High at 48.4 FPS (19.5%), and High-to-Ultra at 71.4 FPS (35.6%). The consistency of these percentage deltas across resolutions suggests that the settings scaling is resolution-independent, which is typical for a well-optimized game engine.

At 3840x2160, the results are 189.8 FPS for Low, 155.9 FPS for Medium, 125.6 FPS for High, and 77.8 FPS for Ultra. The Low-to-Medium gap narrows to 33.9 FPS (17.9%), while the Medium-to-High gap is 30.3 FPS (19.4%), and High-to-Ultra remains the largest at 47.8 FPS (38.1%). Notably, the 4K Low result of 189.8 FPS is actually lower than the 1080p Ultra result of 180.3 FPS, which is a narrow margin that underscores how resolution scaling interacts with settings to determine the final frame rate.

How This Combo Ranks

The AMD Ryzen 9 5900X and NVIDIA GeForce RTX 5080 combination ranks 81st out of 1741 tested combos in Downfall, placing it in the top 4.7% of all configurations in the database. This strong ranking reflects the balanced nature of the pairing: the CPU's 90th percentile ranking among all processors (with an average benchmark score of 39453) and the GPU's 89th percentile ranking among all GPUs combine to produce a system that excels in both CPU-bound and GPU-bound scenarios.

The CPU's nearest rivals in the database include the AMD EPYC 4245P (0.2% higher average score), the AMD Ryzen 7 PRO 8845HS (0.7% lower), the Intel Core i7-13700F (0.9% higher), and the Intel Core i7-13700 (1.0% lower). These tiny deltas indicate that the Ryzen 9 5900X is performing exactly at its expected level, with no anomalous behavior inflating or deflating its contribution to the Downfall results. The GPU's nearest rivals — the Intel Arc A570M, Arc Pro A60, and Arc A580 — all fall within 2.6% of the RTX 5080's average benchmark score, further validating that the measured frame rates are representative of the hardware's true capabilities.

Given that Downfall is a horror title from 2016 with a release date in February of that year, the game's engine does not leverage modern features like ray tracing or DLSS. This means the combo's rank of 81 out of 1741 is achieved purely through raw rasterization performance and CPU throughput. The fact that this pairing outranks 95.3% of tested configurations in a game that is nearly a decade old highlights how the Ryzen 9 5900X's Zen 3 architecture and the RTX 5080's Blackwell 2.0 design combine to deliver exceptional performance even in legacy titles. The measured FPS data supports this ranking, with no resolution or settings combination falling below 77.8 FPS average, and the top configuration reaching 386.4 FPS at 1080p Low.
