The performance scaling from 1080p to 4K reveals interesting characteristics about this combo. At High settings, the transition from 1920x1080 (212 FPS) to 2560x1440 (150.1 FPS) represents a 29.2% drop, while moving to 3840x2160 (90.4 FPS) shows a further 39.8% reduction. This scaling pattern indicates that the GPU becomes increasingly stressed as resolution increases.

The Low settings data shows even more dramatic scaling: 312.9 FPS at 1080p drops to 224.9 FPS at 1440p (a 28.1% reduction), then falls to 137.5 FPS at 4K (a 38.9% reduction from 1440p). This consistent pattern across settings suggests the RTX 3080 Ti is the primary limiting factor at higher resolutions, with the Ryzen 5 8400F providing sufficient CPU throughput even at 1080p where framerates exceed 300 FPS.

The Ultra settings curve is particularly telling: 131.7 FPS at 1080p, 92.3 FPS at 1440p, and 55.9 FPS at 4K. The 4K Ultra result falls below 60 FPS, indicating that this resolution and preset combination pushes the GPU to its limits. The scaling from 1440p to 4K at Ultra (a 39.5% drop) closely mirrors the High settings drop, reinforcing that resolution scaling is consistent regardless of quality preset.

Measured FPS Breakdown

At 1920x1080, the system delivers 312.9 FPS on Low, 258.1 FPS on Medium, 212 FPS on High, and 131.7 FPS on Ultra. The step from Low to Medium costs 54.8 FPS, Medium to High costs 46.1 FPS, and High to Ultra costs 80.3 FPS. The Ultra preset's significant penalty suggests it enables particularly demanding effects.

Moving to 2560x1440, the results are 224.9 FPS on Low, 183.4 FPS on Medium, 150.1 FPS on High, and 92.3 FPS on Ultra. Each settings step costs roughly 30-40 FPS until the Ultra jump, which imposes a 57.8 FPS penalty over High. This pattern indicates that Ultra settings at 1440p stress the GPU considerably more than lower presets.

At 3840x2160, the system produces 137.5 FPS on Low, 111 FPS on Medium, 90.4 FPS on High, and 55.9 FPS on Ultra. The progression from Low to Medium (26.5 FPS drop) and Medium to High (20.6 FPS drop) is relatively modest, but the High to Ultra transition (34.5 FPS drop) pushes the system below 60 FPS. The 4K Ultra result of 55.9 FPS is the only sub-60 FPS measurement in the entire dataset.
