Downfall

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 3080 Ti delivers a compelling 4K experience in Downfall, but the data shows that the Ultra preset is not viable at high resolutions, while Medium and High offer the best balance of performance and visual fidelity across the board.

Settings Recommendations

Based on the measured FPS data, the High preset at 2560x1440 is the sweet spot for this combination, delivering an average of 149 FPS. This provides a significant performance cushion over the 60 FPS threshold while maintaining the visual upgrades over Medium. At 3840x2160, High still manages a playable 93 FPS average, making it the strongest choice for 4K displays.

The Ultra preset is problematic. At 4K it drops to 58 FPS, which is below the 60 FPS target for smooth gameplay. Even at 1440p, Ultra only reaches 93 FPS, which is identical to the High preset at 4K. The performance cost of Ultra is steep: at 1080p, Ultra averages 130 FPS, a 38% reduction compared to High at the same resolution. This suggests Ultra introduces effects that disproportionately tax the GPU without a corresponding visual return.

Medium is a viable fallback for players prioritizing frame rates. At 4K, Medium averages 113 FPS with a minimum of 96 FPS, ensuring consistent performance. The jump from Medium to High at 4K is 20 FPS (from 113 to 93), which is a moderate cost for the visual improvement. At 1080p, Medium hits 254 FPS, making it an excellent choice for high-refresh-rate monitors.

Low is only recommended for extreme frame rate targets. At 1080p, it reaches 284 FPS, which is useful for 240Hz displays, but the visual compromises are substantial. The data indicates that the RTX 3080 Ti has enough headroom at lower resolutions that Low is rarely necessary; even High at 1080p produces 208 FPS.

For the best overall experience, High at 1440p is recommended. It offers a 149 FPS average, which is well above the refresh rate of most gaming monitors, and the gap to Ultra is not justified by the performance loss. For 4K users, High is the only preset that maintains both visual quality and playability, with a 93 FPS average that leaves room for minor frame drops without hitting the 60 FPS floor.

This ranking reflects the balanced nature of the pairing, where the GPU provides ample performance across all resolutions while the CPU avoids becoming a bottleneck.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but predictable. At High settings, 1080p averages 208 FPS, 1440p averages 149 FPS, and 4K averages 93 FPS. This represents a 28% reduction from 1080p to 1440p, and a further 38% reduction from 1440p to 4K. The total drop from 1080p to 4K at High is 115 FPS, a 55% decrease.

At Low settings, the scaling is more aggressive. 1080p averages 284 FPS, 1440p averages 222 FPS, and 4K averages 138 FPS. The drop from 1080p to 1440p is 22%, and from 1440p to 4K is 38%. The total reduction from 1080p to 4K at Low is 146 FPS, a 51% decrease.

The Medium preset shows similar patterns. 1080p averages 254 FPS, 1440p averages 182 FPS, and 4K averages 113 FPS. The reduction from 1080p to 1440p is 28%, and from 1440p to 4K is 38%. The total drop is 141 FPS, a 56% decrease.

At Ultra, the scaling is the most dramatic. 1080p averages 130 FPS, 1440p averages 93 FPS, and 4K averages 58 FPS. The reduction from 1080p to 1440p is 28%, and from 1440p to 4K is 38%. The total drop is 72 FPS, a 55% decrease.

The consistent 38% reduction from 1440p to 4K across all settings indicates that the GPU is the limiting component at higher resolutions. The pixel count increase from 1440p to 4K is 2.25x, but the FPS drop is only 38%, suggesting that the game’s rendering workload is not purely pixel-bound. The RTX 3080 Ti’s 912.4 GB/s memory bandwidth appears sufficient to feed the GPU at 4K, as evidenced by the playable High preset results.

The scaling behavior points to a GPU-bound scenario at all resolutions. The CPU’s role becomes less significant as resolution increases, and the consistent FPS drops align with the GPU’s rendering capacity. The fact that the 1440p-to-4K drop is uniform across presets suggests that the GPU’s compute units are the primary constraint, rather than memory bandwidth or texture fill rate.
