Downfall

Measured FPS Breakdown

The measured frame rates for this Intel Core Ultra 7 270K Plus with Intel Arc B580 combination in Downfall show a clear pattern of diminishing returns as resolution increases. At 1920x1080, the system delivers a wide range of performance depending on the preset selected, from a very fluid 185 FPS average at Low settings down to 77 FPS average at Ultra. The Medium preset at this resolution yields 151 FPS average with a minimum of 128 FPS and a maximum of 174 FPS, indicating strong frame pacing. High settings produce 124 FPS average, which is comfortably above the 60 FPS playability threshold.

Moving to 2560x1440, the performance envelope tightens considerably. Low settings still deliver 132 FPS average, while Medium achieves 108 FPS average with a minimum of 92 FPS and a maximum of 124 FPS. The High preset drops to 88 FPS average, which remains playable, but Ultra falls to 55 FPS average, dipping below the 60 FPS threshold. The step from Medium to High at this resolution costs approximately 20 FPS, while the step from High to Ultra costs 33 FPS, showing that the Ultra preset imposes a disproportionate penalty.

At 3840x2160, the system struggles to maintain playability across the higher presets. Low settings yield 82 FPS average, Medium produces 67 FPS average with a minimum of 57 FPS and a maximum of 77 FPS, and High drops to 55 FPS average. Ultra at 4K is the worst case, with only 34 FPS average. The gap between Low and Medium at 4K is 15 FPS, while the gap between Medium and High is 12 FPS, and the gap between High and Ultra is a steep 21 FPS. Notably, the 4K Medium preset's minimum of 57 FPS sits just below the 60 FPS threshold, suggesting occasional stutter in demanding scenes.

The data reveals that the Intel Arc B580's 12 GB memory buffer and 456.0 GB/s bandwidth are sufficient for medium settings at 4K, but the rendering load at Ultra across all resolutions grows faster than the GPU's 13.67 TFLOPS compute can sustain. Across all resolutions, the Low to Medium transition costs roughly 20-25% performance, while Medium to High costs another 15-20%, and High to Ultra costs the largest relative drop at 30-40%.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS average is Medium, which delivers 67 FPS. Low settings achieve 82 FPS but sacrifice visual fidelity, and Medium represents the highest quality option that remains playable. The minimum FPS at Medium is 57, which is close to the threshold, but the average comfortably clears it.

At 2560x1440, High settings deliver 88 FPS average, making it the best visual preset that maintains playability. Medium achieves 108 FPS and Low reaches 132 FPS, but High offers the best balance of quality and performance. Ultra at 55 FPS falls short of the 60 FPS requirement.

At 1920x1080, Ultra settings deliver 77 FPS average, which is the most demanding preset that clears the 60 FPS threshold. This is notable because the same preset fails at both higher resolutions. High, Medium, and Low all exceed 60 FPS as well, with 124, 151, and 185 FPS respectively, but Ultra is the maximum quality option available.

The Verdict

This PC configuration can run Downfall, but the experience varies sharply by resolution. At 1920x1080, the system clears 60 FPS on every preset, including Ultra at 77 FPS average. This is the resolution where the combination of the Intel Core Ultra 7 270K Plus and Intel Arc B580 shows its full capability. At 2560x1440, the system remains playable on High, Low, and Medium presets, with High at 88 FPS being the best quality option. Ultra at 55 FPS fails the threshold, so 1440p users must cap their settings at High.

At 3840x2160, only Low and Medium presets are playable, with Medium at 67 FPS being the best option. High and Ultra fall to 55 and 34 FPS respectively, which are not smooth enough for consistent gameplay. The verdict data confirms that 4K gaming is possible but requires careful preset selection. Overall, the system is best suited to 1080p and 1440p gaming, where it can push high visual quality with headroom above the 60 FPS target.

How This Combo Ranks

In the benchmark database, this Intel Core Ultra 7 270K Plus plus Intel Arc B580 combination ranks 2802 out of 3716 tested combos for Downfall. This places the system in the lower third of all configurations, which aligns with the measured FPS data showing that 4K Ultra is unplayable and 1440p Ultra barely misses the threshold. The rank reflects the GPU's mid-tier positioning—the Arc B580 sits at the 68th percentile among all GPUs—while the CPU is far stronger at the 96th percentile. The bottleneck is clearly the GPU, as evidenced by the large frame rate drops when increasing resolution.

The rank also suggests that many other tested combinations, likely featuring higher-end GPUs, achieve better performance in this horror title. However, the combination is not at the bottom of the rankings, and the 1080p Ultra result of 77 FPS shows that the system handles the game well at mainstream resolutions. The 3716 total combos indicate a large database, and a rank of 2802 means roughly 75% of tested configurations outperform this one, which is consistent with the Arc B580's 68th percentile GPU ranking.

CPU and GPU Roles

The data reveals an interesting split in component roles across resolutions. At 1920x1080, the CPU's strong single-thread performance appears to support high frame rates even at Ultra settings, where the GPU is less likely to be the sole bottleneck. The 1080p Ultra result of 77 FPS, compared to the 1440p Ultra result of 55 FPS, shows a 29% drop when pixel count increases by 78%, indicating that the GPU becomes progressively more dominant as resolution rises.

At 2560x1440, the scaling from Low to Ultra shows a clear GPU-bound pattern, with frame rates dropping from 132 to 55 FPS. The CPU's 24 cores and 24 threads, along with its 36 MB of shared L3 cache, are sufficient to feed the Arc B580 at this resolution, as evidenced by the strong 108 FPS Medium result. At 3840x2160, the GPU is definitively the limiting factor. The 4K Low result of 82 FPS versus the 4K Ultra result of 34 FPS represents a 59% reduction, while the CPU's workload remains similar across presets.

The scaling between resolutions further clarifies the GPU's role. At Medium settings, the frame rate drops from 151 FPS at 1080p to 108 FPS at 1440p (a 28% reduction), then to 67 FPS at 4K (a 38% further reduction). This non-linear scaling is characteristic of GPU memory bandwidth and fill rate limits—the Arc B580's 456.0 GB/s bandwidth and 213.6 GPixel/s pixel rate are taxed increasingly heavily as resolution climbs. The CPU, by contrast, shows its strength in the 1080p Low result of 185 FPS, which is the highest measured frame rate and suggests that the processor is not constraining the system at mainstream settings. For players targeting 4K, the GPU is the component to upgrade; for those at 1080p, the current balance is nearly optimal.
