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

The frame rate scaling across resolutions reveals a classic pattern of a system becoming increasingly GPU-limited as pixel count rises. Starting at 1080p with the High preset, the system achieves an average of 165 FPS. When moving to 1440p, the average drops to 107 FPS, a decrease of 58 FPS (or 35%). This substantial drop indicates that the GPU is working significantly harder to render the additional pixels.

The trend continues when scaling to 4K, where the same High preset yields an average of just 58 FPS. This is a further 49 FPS reduction from 1440p, representing a 46% drop. The scaling from 1080p to 4K results in a total performance loss of 107 FPS, meaning the 4K frame rate is only 35% of the 1080p frame rate. This steep curve is a clear indicator that the NVIDIA GeForce RTX 5070 is the primary limiting factor at higher resolutions.

However, the data also suggests that at 1080p, the CPU plays a more significant role. With the Low preset at 1080p, the system reaches 224 FPS. This is a 36% increase over the High preset at the same resolution (165 FPS). If the GPU were the sole bottleneck even at 1080p, we would expect a smaller difference between presets. The fact that lowering settings yields such a large gain indicates that the CPU has enough headroom to push the GPU harder, but the GPU's rendering workload is still a major factor. The pattern of diminishing returns as resolution increases firmly establishes the GPU as the bottleneck at 4K, while both components are more balanced at 1080p.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured frame rates provide a detailed look at the system's performance across all tested configurations. The data is presented for each resolution and all four settings presets.

3840x2160 (4K):

• Low: The average FPS is 79.
• Medium: The average FPS is 68, with a minimum of 58 and a maximum of 79.
• High: The average FPS is 58.
• Ultra: The average FPS is 47.

2560x1440 (1440p):

• Low: The average FPS is 145.
• Medium: The average FPS is 126, with a minimum of 107 and a maximum of 145.
• High: The average FPS is 107.
• Ultra: The average FPS is 87.

1920x1080 (1080p):

• Low: The average FPS is 224.
• Medium: The average FPS is 195, with a minimum of 166 and a maximum of 224.
• High: The average FPS is 165.
• Ultra: The average FPS is 135.

The data shows a clear and consistent hierarchy across all resolutions. The Low preset always yields the highest average FPS, followed by Medium, High, and finally Ultra. This is expected, as the higher presets increase the rendering workload on the GPU. The gap between Low and Ultra is significant. At 1080p, the difference is 89 FPS (224 vs 135), and at 4K, it is 32 FPS (79 vs 47). This highlights the substantial impact that graphical settings have on performance, particularly at lower resolutions where the GPU is less saturated.

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

Based on the measured FPS data, the optimal settings preset depends heavily on the user's target resolution and refresh rate.

For 4K (3840x2160), the Medium preset is the clear recommendation. It achieves an average of 68 FPS, which is above the 60 FPS threshold for smooth gameplay. The High preset dips to 58 FPS, which, while playable, is noticeably less fluid and risks dropping below the refresh rate of many 4K monitors. The Ultra preset, at 47 FPS, is not recommended for a consistently smooth experience, and the Low preset, while faster, sacrifices too much visual fidelity for the gains. Medium provides the best balance of visual quality and performance for a 60 Hz display.

For 1440p (2560x1440), the High preset is the best choice for most players. It delivers an average of 107 FPS, which is excellent for a high-refresh-rate monitor (100Hz-120Hz). The Ultra preset still provides a very good 87 FPS average, suitable for a standard 60Hz or 75Hz monitor, but the jump to High offers a significant 20 FPS boost for a minor visual trade-off. For those with 144Hz displays, the Medium preset, at 126 FPS, could be considered, but the High preset's 107 FPS is likely the sweet spot for balancing visual fidelity and speed.

For 1080p (1920x1080), the system has ample power to drive high refresh rates even at the highest settings. The Ultra preset delivers an average of 135 FPS, which is more than enough for a smooth experience on a 120Hz or 144Hz monitor. Players with a 165Hz or higher refresh rate display could opt for the High preset, which pushes the average to 165 FPS. The Medium preset, at 195 FPS, is ideal for esports-focused players with 200Hz+ monitors, but the visual downgrade from High is significant. The Low preset, at 224 FPS, offers the absolute highest frame rate for competitive play but should be avoided for a visually rich single-player experience. In this case, the High preset offers the best overall experience, providing a frame rate high enough to saturate most high-refresh displays while maintaining a high level of graphical detail.
