Downfall

Downfall, a horror title from 2016, exhibits a wide performance envelope depending on the graphics preset and resolution chosen. The measured data for the Intel Core Ultra 9 290K Plus and AMD Radeon RX 6800 XT combination reveals a system capable of high refresh rates at 1080p and 1440p, but one that requires careful settings management to maintain smooth gameplay at 4K. The benchmark results indicate a clear hierarchy where the GPU becomes the primary bottleneck as resolution increases, with the CPU's substantial headroom only becoming apparent at lower resolutions and settings.

Settings Recommendations

Based on the measured FPS data, the optimal experience balances visual fidelity with frame time consistency. At 1920x1080, the High preset delivers an average of 195 FPS, which is a significant drop from the 291 FPS seen at Low but still exceptionally smooth. However, the Medium preset at 1080p yields 238 FPS, which represents a 22% improvement over High while likely offering a more stable frame pacing for a horror title where sudden drops can be jarring. The data shows that Ultra at 1080p produces 122 FPS, which is more than enough for most displays, but the jump from Medium to Ultra costs 116 FPS, a 49% reduction, making it a less efficient choice for competitive play.

At 2560x1440, the High preset is the sweet spot, achieving 139 FPS. This is a 36% improvement over the Ultra preset's 87 FPS, while only sacrificing a modest amount of visual quality. The Medium preset at 1440p offers 170 FPS, but the data shows a min FPS of 144, which is still well within the range of high-refresh-rate monitors. For a horror game, maintaining a high minimum frame rate is crucial to avoid stutter during intense scenes, and the High preset's performance headroom over Ultra provides a safer margin.

The most demanding scenario is at 3840x2160. Here, the High preset produces 87 FPS, which is playable but not ideal for a 120Hz or 144Hz display. The Medium preset at 4K delivers 106 FPS, with a minimum of 90 FPS, making it the only 4K option that consistently stays above the 90 FPS threshold. While Ultra at 4K drops to 54 FPS, the data suggests that Medium is the recommended preset for 4K gaming, as it offers a 96% performance increase over Ultra while maintaining a playable frame rate. The Low preset at 4K reaches 129 FPS, but the visual compromise is likely too severe for a game that relies on atmosphere and detail.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this configuration for Downfall. Its 16 GB of GDDR6 memory on a 256-bit bus provides 512.0 GB/s of bandwidth, which is more than sufficient for this title's texture and geometry demands at all tested resolutions. The GPU's RDNA 2.0 architecture, built on a 7 nm process, includes 4608 shading units and 128 ROPs, allowing it to handle the game's lighting and shadow effects efficiently. The boost clock of 2250 MHz and game clock of 2015 MHz are the primary drivers of its raw throughput.

The data shows a clear pattern: as resolution increases from 1920x1080 to 3840x2160, the average FPS at the same settings drops significantly. At High settings, the FPS falls from 195 at 1080p to 139 at 1440p, a 29% reduction, and then to 87 at 4K, a 55% reduction from 1080p. This scaling is typical of a GPU-bound scenario, where the number of pixels rendered directly impacts the workload. The RX 6800 XT's 20.74 TFLOPS of FP32 compute is being fully utilized at higher resolutions, and its performance relative to other GPUs is notable; it sits at the 85th percentile among all GPUs, with an average benchmark score of 48477.

The GPU's nearest rivals in the benchmark database include the NVIDIA RTX A1000 Mobile, which it leads by 1.5%, and the Intel Arc A550M, which leads it by 2.5%. The RX 6800 XT also trails the NVIDIA GeForce RTX 5070 Ti and AMD Radeon RX Vega 64 by 3% each. This places the RX 6800 XT in a competitive mid-to-high tier, and its 16 GB VRAM capacity ensures that even Ultra settings in Downfall, which likely uses high-resolution textures, will not exceed the memory buffer. The data does not show any VRAM-related performance cliffs, suggesting the memory subsystem is not a limiting factor in this game.

Resolution Scaling

The FPS scaling across resolutions is a direct indicator of where the system bottleneck lies. At 1080p with Low settings, the average FPS is 291, which is likely near the CPU's maximum frame output for this game. When moving to 1440p Low, the FPS drops to 207, a 29% decrease, and at 4K Low, it drops further to 129, a 56% decrease from 1080p. This scaling is steeper than what would be expected from a purely CPU-limited scenario, indicating that even at Low settings, the GPU is becoming a significant factor at higher resolutions.

Conversely, at Ultra settings, the scaling is even more pronounced. The FPS goes from 122 at 1080p to 87 at 1440p, a 29% drop, and then to 54 at 4K, a 56% drop from 1080p. The consistency of this scaling pattern across all settings suggests that the RX 6800 XT is the primary limiter. The CPU, with its 24 cores and 24 threads, is not the constraining factor in these scenarios; its high benchmark scores, such as the Cinebench R23 multicore score of 51731, indicate it has ample headroom.

The data reveals that the performance gap between Low and Ultra settings widens as resolution decreases. At 4K, the difference between Low (129 FPS) and Ultra (54 FPS) is 75 FPS, while at 1080p, the difference is 169 FPS (291 vs 122). This is because at lower resolutions, the CPU can feed frames faster, allowing the GPU's settings-dependent workload to become more dominant. At 4K, the GPU is already near its limit even at Low settings, so the additional load from Ultra settings has a smaller absolute impact. The FPS drop from 1080p to 4K averages around 55% across all settings, indicating that the pixel count is the primary variable driving performance.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's capabilities. At 1920x1080, the Low preset achieves an average of 291 FPS, the highest recorded in the dataset. The Medium preset follows with 238 FPS, with a minimum of 202 FPS and a maximum of 273 FPS, showing a tight frame time distribution. The High preset delivers 195 FPS, while the Ultra preset drops to 122 FPS. The scaling from Low to Ultra represents a 58% performance loss, which is substantial but expected given the visual enhancements.

At 2560x1440, the Low preset produces 207 FPS, a 29% reduction from 1080p. The Medium preset achieves 170 FPS, with a minimum of 144 FPS and a maximum of 195 FPS, maintaining a 144 FPS floor. The High preset delivers 139 FPS, which is still above the 120 FPS threshold for high-refresh-rate gaming. The Ultra preset drops to 87 FPS, a 37% reduction from High, making it less suitable for fast-paced sequences. The transition from 1080p to 1440p costs an average of 29% performance across all settings.

At 3840x2160, the Low preset yields 129 FPS, which is surprising for a 4K resolution and indicates the game's low settings are not very demanding. The Medium preset achieves 106 FPS, with a minimum of 90 FPS, making it the only 4K setting that consistently stays above 90 FPS. The High preset drops to 87 FPS, while the Ultra preset falls to 54 FPS, a 50% reduction from Medium. The data shows that 4K Ultra is only viable for 60Hz displays, while 4K Medium is the recommended choice for high refresh rates.
