With Low settings, the average FPS is 411.4, which is more than sufficient for any high-refresh-rate monitor. Medium settings reduce this to 346.7 FPS, while High settings yield 283.6 FPS. The Ultra preset at 1080p produces 178.5 FPS, which remains well above the 144 Hz threshold for smooth gameplay.

Moving to 2560x1440, the frame rates remain high but show more variation. Low settings produce 303.6 FPS, a 26.2% drop compared to 1080p Low. Medium settings deliver 245.9 FPS, High settings achieve 205.4 FPS, and Ultra settings drop to 125.7 FPS. The step from High to Ultra at 1440p costs 79.7 FPS, a 38.8% reduction, which mirrors the 4K pattern. At 1440p, even the Ultra preset maintains playable frame rates, though it falls below the 144 Hz mark.

At 3840x2160, the highest resolution tested, the system still delivers strong performance but with clear limitations. Low settings produce 188 FPS, which is excellent for 4K gaming. Medium settings yield 152.5 FPS, and High settings achieve 124.8 FPS. The Ultra preset drops to 76.7 FPS, which is below the 100 FPS threshold for optimal smoothness but still playable for a horror title where atmosphere matters more than competitive frame rates.

The scaling pattern across resolutions is consistent: Low settings at 4K (188 FPS) are comparable to Ultra settings at 1440p (125.7 FPS) in terms of the gap between presets. The data shows that the system is capable of exceeding 200 FPS at 1080p and 1440p on High settings, and exceeding 100 FPS at 4K on High settings. The Ultra preset, however, presents a significant challenge at 4K, with frame rates dropping by 38.6% compared to High settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1920x1080, all presets deliver frame rates above 170 FPS, making the choice driven by visual quality preferences rather than performance constraints. Ultra at 1080p produces 178.5 FPS, which is still well above the 144 Hz mark, so players with 144 Hz monitors can comfortably use Ultra settings.

For 2560x1440, the High preset at 205.4 FPS offers an excellent balance of visual fidelity and performance. The Ultra preset at 125.7 FPS is also viable for 120 Hz displays, but the 38.8% performance drop compared to High may not justify the visual improvements. For players with 144 Hz or higher refresh rates, High settings are the recommended choice, as they maintain frame rates above 200 FPS.

At 3840x2160, the High preset at 124.8 FPS is the best option for a smooth experience, as it comfortably exceeds 120 FPS. The Medium preset at 152.5 FPS offers even higher performance for players with 144 Hz 4K displays, though it sacrifices some visual quality. The Ultra preset at 76.7 FPS is only recommended for players who prioritize visual fidelity over frame rate, as it approaches the 60-75 FPS range typically considered playable for cinematic horror experiences. The Low preset at 188 FPS is unnecessary for most players, as the visual quality reduction is substantial relative to the performance gain.

The data suggests that the High preset provides the most consistent experience across all three resolutions, with frame rates of 283.6 FPS at 1080p, 205.4 FPS at 1440p, and 124.8 FPS at 4K. This preset offers a good balance between visual quality and performance, making it the recommended choice for most users.
