Settings Recommendations — which preset gives the best experience per the measured rows

For the best balance of visual quality and performance, the Medium preset at 2560x1440 is the optimal choice, delivering 97 FPS average with a minimum of 82 FPS. This configuration allows for smooth gameplay on most monitors while maintaining acceptable visual fidelity. The 1080p Medium preset is even more compelling, achieving 140 FPS average with a minimum of 119 FPS, which is ideal for high-refresh-rate displays.

At 4K, the Medium preset at 57 FPS average with a 49 FPS minimum is the only viable option for maintaining playability, though it falls short of 60 FPS average. The Low preset at 4K provides 85 FPS, which is smoother but sacrifices visual quality. For players prioritizing competitive performance over visuals, the 1080p Low preset at 209 FPS is the clear winner, providing maximum frame rates with minimal input lag.

The High preset offers diminishing returns over Medium, with only a 22 FPS difference at 1440p (82 vs 97 FPS) and a 9 FPS difference at 1080p (119 vs 140 FPS). The Ultra preset shows the largest performance hit, with 4K dropping to 37 FPS and 1440p to 62 FPS, making it unsuitable for most gaming scenarios. Based on the measured data, Medium settings provide the best experience across all resolutions, balancing visual enhancements with frame rate stability.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling from 1080p to 4K reveals a clear transition in the bottleneck component. At Low settings, the average FPS drops from 209 at 1080p to 144 at 1440p (a 31% reduction) and then to 85 at 4K (an additional 41% reduction). This steep decline at 4K indicates that the GPU is the limiting factor, as the CPU should be able to maintain high frame rates given its strong single-thread performance.

At Medium settings, the scaling is more gradual: 140 FPS at 1080p, 97 FPS at 1440p (a 31% drop), and 57 FPS at 4K (a further 41% drop). The proportional decreases suggest that the GPU’s workload scales consistently with pixel count, confirming that the RX 6800 XT’s 512.0 GB/s bandwidth and 4608 shading units are the primary constraints at higher resolutions. The CPU’s role diminishes as resolution increases, which is typical for modern games where GPU fill rate dominates.

The High settings show a similar pattern: 119 FPS at 1080p, 82 FPS at 1440p (31% drop), and 48 FPS at 4K (41% drop). Ultra settings follow the same trend, with 90 FPS at 1080p, 62 FPS at 1440p (31% drop), and 37 FPS at 4K (40% drop). The consistent percentage drops across all settings indicate a linear GPU scaling behavior, meaning the CPU is never a bottleneck at any resolution. This analysis confirms that while the i5-14600K provides ample processing power, the RX 6800 XT reaches its limits at 4K, making 1440p the sweet spot for this pairing.
