Downfall

Resolution Scaling

The measured FPS data for Downfall reveals a pronounced sensitivity to resolution, with the AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 3080 Ti combination showing a clear progression from extremely high frame rates at 1080p to more moderate numbers at 4K. At the Low preset, the system delivers 313.6 FPS at 1920x1080, which drops to 219.3 FPS at 2560x1440—a reduction of approximately 30%—and then to 140.7 FPS at 3840x2160, which is about 36% lower than the 1440p result. This scaling pattern indicates that while the CPU is capable of driving very high frame rates at lower resolutions, the GPU becomes increasingly dominant as pixel count rises.

The gap between 1080p and 4K at Low settings is substantial: the 4K figure of 140.7 FPS is only 44.9% of the 1080p result. This is a classic sign that the rendering pipeline is shifting from CPU-bound at 1080p to GPU-bound at 4K. The Ryzen 9 9950X3D, with its 16 cores, 32 threads, and 128 MB of shared L3 cache, is more than adequate to feed the RTX 3080 Ti at lower resolutions, but the sheer pixel throughput required at 4K overwhelms even this capable GPU.

At the High preset, the scaling is steeper: 209 FPS at 1080p falls to 146.4 FPS at 1440p (a 30% drop) and then to 92.6 FPS at 4K (a 37% drop from 1440p). The Ultra preset shows a similar pattern, with 128.6 FPS at 1080p, 91.6 FPS at 1440p, and 57.7 FPS at 4K. Notably, the drop from 1080p to 4K at Ultra is 55%, which is the largest relative decline across all presets. This suggests that the additional shading and texture work at Ultra settings amplifies the GPU's workload more than the CPU's, reinforcing that the RTX 3080 Ti is the limiting component at high resolutions and quality levels.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture with a GA102 chip, fabricated on Samsung's 8 nm process. It features 12 GB of GDDR6X memory on a 384-bit bus, yielding a bandwidth of 912.4 GB/s—a figure that is critical for high-resolution texture streaming in a horror title like Downfall, which often relies on dense environmental detail. The GPU's base clock is 1365 MHz, with a boost clock of 1665 MHz, and it contains 10,240 shading units, 320 TMUs, and 112 ROPs. These specifications translate to a pixel rate of 186.5 GPixel/s and a texture rate of 532.8 GTexel/s, which are directly relevant to the frame rates observed.

The RTX 3080 Ti's 34.10 TFLOPS of FP32 compute is substantial, but the data shows that at 1080p Low, the system reaches 313.6 FPS, which is likely near the CPU's practical limit for this game. The Ryzen 9 9950X3D, with its 5.70 GHz boost clock and high single-thread performance (3,540 in Cinebench R20 single-core), is clearly not the bottleneck at lower resolutions. However, at 4K Ultra, the GPU's workload increases dramatically, and the 57.7 FPS result reflects the RTX 3080 Ti's struggle to maintain high frame rates with all quality features enabled. The GPU's percentile rank of 83 among all GPUs, with an average benchmark score of 41,224, places it just 0.5% below the NVIDIA GeForce RTX 3090 in average score, indicating that it is a high-end part but not the absolute fastest.

The memory subsystem is particularly relevant here: 12 GB of VRAM is sufficient for 1080p and 1440p at most settings, but at 4K Ultra, the combination of high-resolution textures and heavy post-processing can push memory usage near the limit. The 912.4 GB/s bandwidth helps mitigate this, but the measured FPS drop from 115.5 at 4K Medium to 57.7 at 4K Ultra suggests that the GPU's compute and memory resources are being saturated by the Ultra preset's additional effects. The GPU's clock behavior, with a boost of 1665 MHz, is typical for the Ampere generation, and the data indicates that the RTX 3080 Ti is performing as expected relative to its specifications.

Settings Recommendations

The measured data provides a clear hierarchy for optimal settings in Downfall with this hardware. For players prioritizing high refresh rates, the Low preset at 1920x1080 offers 313.6 FPS, which is far beyond what most displays can show, making it suitable for competitive play or maximum fluidity. However, the visual quality at Low is likely to be minimal, and the Medium preset at 257.7 FPS still provides excellent performance with better graphics.

At 2560x1440, the High preset delivers 146.4 FPS, which is an ideal balance for most users. This frame rate is smooth on high-refresh monitors (144 Hz) and the visual quality is significantly better than Low or Medium. The Medium preset at 180.5 FPS is also viable for those who prefer even higher frame rates, but the 34 FPS difference between Medium and High (180.5 vs. 146.4) may not justify the visual downgrade for most players. The Ultra preset at 91.6 FPS is playable but may feel less responsive, especially in a horror game where quick reactions are sometimes needed.

For 4K gaming, the data suggests that the High preset at 92.6 FPS is the most sensible choice, as it provides a smooth experience on 60 Hz displays and maintains good visual fidelity. The Medium preset at 115.5 FPS offers a buffer for more demanding scenes, while the Ultra preset at 57.7 FPS is borderline—it dips below 60 FPS, which may cause noticeable stutter in a horror title that relies on atmospheric tension. The Low preset at 140.7 FPS is unnecessary for most 4K displays, as the visual compromises outweigh the performance gain.

Overall, the best experience per the measured rows is achieved at 2560x1440 with the High preset, delivering 146.4 FPS. This configuration combines high image quality with frame rates that exceed the refresh rate of most gaming monitors, ensuring a responsive and immersive experience. At 4K, the High preset at 92.6 FPS is the recommended choice, as it maintains a playable frame rate while preserving visual detail. The Ultra preset should be avoided at 4K unless the user is willing to accept sub-60 FPS performance, as the 57.7 FPS result falls short of the smoothness expected in a modern horror game.
