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

The measured FPS data reveals a clear pattern of resolution scaling that points to the GPU as the primary limiter at higher resolutions. At 1080p Low, the system achieves 332 FPS. Moving to 1440p Low drops this to 285 FPS, a reduction of 47 FPS or 14.2%. At 4K Low, the frame rate falls to 178 FPS, which is 46.4% below the 1080p figure. This substantial drop at 4K even on Low settings indicates the GPU is being pushed harder as pixel count increases.

The High settings tier shows similar scaling behavior. From 268 FPS at 1080p, the frame rate drops to 191 FPS at 1440p (a 28.7% reduction) and then to 119 FPS at 4K (a 55.6% reduction from 1080p). The Ultra settings tier follows the steepest curve: 168 FPS at 1080p, 120 FPS at 1440p, and 74 FPS at 4K. The 4K Ultra result represents a 56% drop from the 1080p Ultra figure.

The pattern suggests that at 1080p, the CPU still has headroom to push higher frame rates — the 332 FPS Low result is close to what the RTX 4080 can output when unconstrained. As resolution increases, the GPU’s workload grows significantly, and the frame rate drops accordingly. The RTX 4080’s 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are being exercised more heavily at 1440p and 4K, where texture detail and memory bandwidth demands scale with pixel count.

Interestingly, the 1080p Medium setting shows 309 FPS, which is only 23 FPS below the Low setting. This narrow gap suggests the GPU is not the limiting factor at 1080p Medium — the CPU is likely providing the ceiling. The 1440p Medium result of 233 FPS and 4K Medium of 145 FPS show a gentler scaling curve than the Ultra tier, indicating that Medium settings allow the GPU to maintain higher utilization without hitting memory or shading bottlenecks.

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

At 1920x1080, the system delivers its highest frame rates. Low settings average 332 FPS, Medium averages 309 FPS with a minimum of 263 FPS and maximum of 355 FPS, High averages 268 FPS, and Ultra averages 168 FPS. The spread from Low to Ultra is 164 FPS, with the drop from Medium to High being 41 FPS and from High to Ultra being 100 FPS.

At 2560x1440, performance remains strong but shows the expected reduction. Low averages 285 FPS, Medium averages 233 FPS with a minimum of 198 FPS and maximum of 268 FPS, High averages 191 FPS, and Ultra averages 120 FPS. The drop from 1080p to 1440p is 47 FPS at Low, 76 FPS at Medium, 77 FPS at High, and 48 FPS at Ultra. The consistent reduction across settings indicates the GPU is becoming more stressed at this resolution.

At 3840x2160, the frame rates reveal the GPU’s limits. Low averages 178 FPS, Medium averages 145 FPS with a minimum of 123 FPS and maximum of 167 FPS, High averages 119 FPS, and Ultra averages 74 FPS. The drop from 1440p to 4K is 107 FPS at Low, 88 FPS at Medium, 72 FPS at High, and 46 FPS at Ultra. The Ultra setting shows the smallest absolute drop, suggesting that at this quality level the GPU is already heavily loaded and additional resolution has diminishing impact on the frame rate.

Notable observations include the Medium settings providing the only measured minimum and maximum values across all resolutions. At 4K Medium, the minimum of 123 FPS ensures no frame drops below playable levels, while at 1080p Medium the maximum of 355 FPS shows the system can briefly exceed its average by a significant margin. The Ultra settings at all resolutions lack minimum/maximum data, which may indicate more consistent frame delivery or less variance in the measured runs.

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

Analyzing the measured FPS rows, the Medium preset at 1440p emerges as a sweet spot for most users. At 233 FPS average with a minimum of 198 FPS, this configuration provides smooth gameplay on high-refresh-rate monitors while maintaining visual quality above the Low preset. The 4K Medium option at 145 FPS average with a 123 FPS minimum also delivers excellent performance for 4K displays, though the 4K High preset at 119 FPS is still well above standard 60 Hz refresh rates.

For users with 1080p displays, the Medium preset at 309 FPS offers the best balance — the 263 FPS minimum ensures no noticeable stutter, and the 355 FPS maximum shows the system can handle intense scenes without dropping below competitive frame rates. The High preset at 268 FPS is also viable, but the 41 FPS difference between Medium and High may not justify the visual improvement for players prioritizing raw frame rate.

At 1440p, the Medium preset’s 233 FPS average and 198 FPS minimum make it the recommended choice for competitive play or high-refresh-rate displays. The High preset at 191 FPS still provides excellent performance, and the Ultra preset at 120 FPS is playable on 120 Hz displays. For 4K, the Medium preset at 145 FPS is the best measured option for users who want high frame rates, while the High preset at 119 FPS offers a good balance for 120 Hz displays. The Ultra preset at 74 FPS is only recommended for users prioritizing maximum visual fidelity over frame rate, as it remains above 60 FPS but with less headroom for demanding scenes.

The data suggests that the Low preset is unnecessary for this configuration, as even the Ultra preset at 1080p delivers 168 FPS. The GPU’s 16 GB VRAM and high bandwidth mean there is no memory-related penalty for choosing higher settings, so users can safely select Medium or High without worrying about resource constraints.
