Resolution Scaling

The resolution scaling analysis reveals how the FPS drops as resolution increases, highlighting the GPU's role as the primary bottleneck. From 1920x1080 to 2560x1440 at High settings, the average FPS drops from 158.3 to 103.8, a reduction of 54.5 FPS or approximately 34%. Scaling further to 3840x2160 at High settings, the average FPS falls to 58.9, representing a 63% drop from the 1080p baseline.

This scaling pattern is consistent with GPU-bound behavior. The GTX 1080 Ti's 11.34 TFLOPS of FP32 compute and 484.4 GB/s memory bandwidth become increasingly taxed as pixel count rises. At Low settings, the drop from 1080p (218.9 FPS) to 1440p (142.6 FPS) is 76.3 FPS, while the drop to 4K (78.4 FPS) is 140.5 FPS. The relative consistency of these drops across settings indicates that resolution, rather than settings, is the dominant factor.

The data suggests that at 1080p, the CPU's 6 cores and 12 threads with a 4.40 GHz boost clock can feed the GPU adequately, allowing it to reach 218.9 FPS at Low settings. As resolution increases, the GPU's pixel rate of 139.2 GPixel/s and texture rate of 354.4 GTexel/s become limiting factors. The 4K Ultra result of 47 FPS shows the system struggling at the highest load, indicating that 1440p is the practical ceiling for smooth gameplay at higher settings.

Measured FPS Breakdown

At 1920x1080 resolution, the measured FPS shows a clear progression across settings: Low delivers 218.9 FPS, Medium 191.8 FPS, High 158.3 FPS, and Ultra 130.5 FPS. The gap between Low and Ultra is 88.4 FPS, demonstrating that settings have a significant impact at this resolution. The 1080p results are all well above 60 FPS, making this resolution ideal for high-refresh-rate displays.

Moving to 2560x1440, the results drop but remain respectable: Low produces 142.6 FPS, Medium 122.1 FPS, High 103.8 FPS, and Ultra 85.4 FPS. The difference between Low and Ultra at 1440p is 57.2 FPS, showing that settings still matter but the GPU is beginning to feel the load. All 1440p results remain above 60 FPS, suggesting smooth gameplay is achievable at this resolution.

At 3840x2160, the FPS figures become more constrained: Low delivers 78.4 FPS, Medium 63.3 FPS, High 58.9 FPS, and Ultra 47 FPS. Here, the gap between Low and Ultra narrows to 31.4 FPS, indicating that resolution is the dominant constraint. The Ultra setting at 4K falls below 60 FPS, while High barely exceeds the 60 FPS threshold. This breakdown shows that 4K gaming is possible but requires settings adjustments to maintain smooth frame rates.

GPU Role

The NVIDIA GeForce GTX 1080 Ti's specifications directly influence the measured results.

The 4K Ultra result of 47 FPS directly reflects the GPU's limits. The 58.9 FPS at 4K High shows that reducing settings can bring the system closer to playable thresholds, but the GPU's 250 W TDP and thermal constraints may limit sustained performance. The memory bandwidth of 484.4 GB/s is sufficient for 4K textures, but the compute resources are stretched at this resolution.

Settings Recommendations

The measured FPS data supports specific settings recommendations based on resolution. At 1920x1080, all settings produce playable results, with Ultra delivering 130.5 FPS. This makes Ultra the recommended choice for 1080p gaming, as it provides the best visual quality while maintaining frame rates well above 60 FPS.

At 2560x1440, the High setting (103.8 FPS) offers a strong balance between visual fidelity and performance. Ultra at 85.4 FPS is also viable, but the 18.4 FPS drop from High to Ultra may not justify the visual gains for competitive play. Medium at 122.1 FPS provides headroom for high-refresh-rate displays, while Low at 142.6 FPS is suited for maximum responsiveness.

For 3840x2160, the recommendations become more nuanced. High at 58.9 FPS is on the edge of playability, while Medium at 63.3 FPS provides a safer margin above 60 FPS. Low at 78.4 FPS offers the smoothest experience but sacrifices visual quality. Ultra at 47 FPS is not recommended for 4K, as the sub-60 FPS result may cause noticeable stuttering in fast-paced scenes.

The data indicates that the optimal experience is at 2560x1440 with High settings, where the 103.8 FPS result combines good visuals with smooth gameplay. For users prioritizing frame rate over visuals, 1080p with Ultra settings at 130.5 FPS or 1440p with Low settings at 142.6 FPS are strong alternatives.
