Resolution Scaling

The frame rate data reveals a clear pattern of GPU-bound performance at higher resolutions. Moving from 1920x1080 to 2560x1440 at High settings, the average FPS drops from 128 to 103, a 25 FPS reduction (19.5%). The further move to 3840x2160 at High settings brings the average down to 76 FPS, another 27 FPS reduction (26.2%). This progressive decline aligns with the increasing pixel workload rather than any CPU limitation.

At Low settings, the scaling is more dramatic. The system produces 218 FPS at 1080p, 176 FPS at 1440p, and 130 FPS at 4K. The drop from 1080p to 4K is 88 FPS (40.4%), which is steeper than the High preset's 52 FPS drop (40.6%) in percentage terms. This suggests that at Low settings, the CPU is still capable of driving higher frame rates at 1080p, but the GPU becomes the limiting factor as resolution increases.

The Medium preset shows the most complete data with minimum and maximum frame rates recorded. At 1080p Medium, the system averages 170 FPS with a minimum of 144 and maximum of 195. At 1440p Medium, the average drops to 137 FPS with a minimum of 116 and maximum of 157. At 4K Medium, the average is 101 FPS with a minimum of 86 and maximum of 116. The minimum frame rates at each resolution stay above 60 FPS, indicating consistent performance without severe stutters.

The scaling pattern indicates that at 1080p, the CPU's 12 cores and high boost clock allow the GPU to work near its full potential at Low settings, but game engine limitations or CPU overhead prevent higher frame rates. At 4K, the GPU's 16 GB of VRAM and 960 GB/s bandwidth become the decisive factors, with the system delivering playable but progressively lower frame rates as settings increase.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 218 FPS, Medium averages 170 FPS with a minimum of 144 and maximum of 195, High averages 128 FPS, and Ultra averages 122 FPS. The gap between Low and Ultra is 96 FPS, representing a 44% reduction in performance when maxing out all settings. The relatively small difference between High (128 FPS) and Ultra (122 FPS) suggests diminishing returns at the top end.

Moving to 2560x1440, the frame rates scale down proportionally. Low averages 176 FPS, Medium averages 137 FPS with a minimum of 116 and maximum of 157, High averages 103 FPS, and Ultra averages 98 FPS. The spread between Low and Ultra is 78 FPS, a 44.3% reduction. The Medium preset's minimum of 116 FPS remains well above the 60 FPS threshold, indicating smooth gameplay even during demanding scenes.

At 3840x2160, the system still maintains playable frame rates but with a narrower margin. Low averages 130 FPS, Medium averages 101 FPS with a minimum of 86 and maximum of 116, High averages 76 FPS, and Ultra averages 72 FPS. The difference between Low and Ultra is 58 FPS, a 44.6% reduction. The Ultra preset's 72 FPS average is above 60 FPS but does not provide as much headroom for complex scenes or add-on content that could cause frame drops.

The data shows a consistent pattern where the percentage reduction from Low to Ultra settings remains relatively stable across resolutions (44-44.6%), indicating that the settings impact is multiplicative rather than additive. The Medium preset consistently delivers the highest minimum frame rates relative to its average, making it the most predictable option for maintaining consistent performance.

Settings Recommendations

The measured data suggests that the Medium preset offers the best balance of performance and visual quality for this system. At 1440p Medium, the system delivers 137 FPS average with a 116 FPS minimum, providing smooth gameplay with room to spare for complex scenery or weather effects. At 4K Medium, the 101 FPS average with an 86 FPS minimum maintains a comfortable margin above 60 FPS, making it the highest settings level that guarantees playable performance at the maximum resolution.

For users prioritizing maximum visual fidelity, the Ultra preset at 1440p delivers 98 FPS average, which is still highly playable. At 4K Ultra, the 72 FPS average is above the 60 FPS threshold but offers less headroom for performance dips during heavy scenes like crowded airports or detailed urban areas. The High preset at 4K provides 76 FPS, which is only 4 FPS higher than Ultra, suggesting that the additional 4 FPS gained by dropping from Ultra to High may not justify the visual compromise.

The Low preset at 1080p produces 218 FPS, which is valuable for competitive or high-refresh-rate scenarios, but the visual quality reduction is significant. The data indicates that Medium at any resolution provides the most consistent frame pacing, as evidenced by the minimum frame rates being closest to the average. For most users, the Medium preset at 1440p or 4K represents the sweet spot, delivering frame rates that are 2.3 to 1.7 times higher than the 60 FPS baseline while maintaining visual fidelity that is appropriate for the game's detailed environments.
