Lockdown Protocol

Resolution Scaling

The performance drop from 1080p to 4K is steep but uneven across settings, revealing where the bottleneck shifts. At Low settings, the RTX 4090 + i5-11400F combo delivers 231.9 FPS at 1080p, which falls to 209.1 FPS at 1440p and 176.1 FPS at 4K. That is a 24% reduction from 1080p to 4K, indicating the GPU remains dominant even at lower presets. However, at Ultra settings, the scaling is far more aggressive: 174.1 FPS at 1080p, 126.4 FPS at 1440p, and 82.1 FPS at 4K. The 4K Ultra figure represents a 53% drop from 1080p Ultra, showing that the game’s highest preset imposes a heavy shading and memory bandwidth load that scales nearly linearly with pixel count.

The data suggests that at 1080p and 1440p, the processor is not the limiting factor for most presets. At 1080p Low, the combo reaches 231.9 FPS, while at 1440p Low it still holds 209.1 FPS — a modest 10% decline that points to GPU headroom rather than CPU saturation. The real divergence appears at 4K. At 4K High, the average is 106.1 FPS, and at 4K Ultra it falls to 82.1 FPS, while 4K Medium sits at 126.1 FPS. The gap between 4K Low (176.1 FPS) and 4K Ultra (82.1 FPS) is a 2.1x difference, confirming that resolution scaling is entirely GPU-bound once pixel count rises. For users targeting 4K, the i5-11400F’s six cores are sufficient to feed the RTX 4090, but the GPU’s 24 GB frame buffer and 1.01 TB/s bandwidth are what determine the outcome.

How This Combo Ranks

In the benchmark database, this combination of Intel Core i5-11400F and NVIDIA GeForce RTX 4090 ranks 119th out of 1,637 tested combos for Lockdown Protocol. That places it in the top 7% of all configurations, a strong result given the processor’s age. The i5-11400F itself sits at the 75th percentile among all CPUs, while the RTX 4090 sits at the 91st percentile among all GPUs. The combo’s rank of 119, however, is lower than the GPU’s percentile would suggest, implying that the CPU holds back the system in this FPS title.

The nearest CPU rivals in general benchmarks are the AMD Ryzen 7 5700U (0% delta), Intel Core i7-1260P (-0.2%), Intel Core Ultra 7 164U (-0.2%), and Intel Core i5-1240U (0.2%). These processors have similar average scores to the i5-11400F, but none of them are paired with an RTX 4090 in the measured data. The combo’s rank of 119 out of 1,637 means that 118 other configurations achieve higher average FPS in Lockdown Protocol. Given that the RTX 4090 is one of the fastest GPUs in the database, the ranking reflects the CPU’s inability to fully exploit it at lower resolutions. At 1080p Low, the combo hits 231.9 FPS, but many higher-ranked combos likely pair newer CPUs with similar GPUs, yielding higher frame rates in CPU-light scenarios.

GPU Role

The RTX 4090’s specifications are central to understanding these results. It features 24 GB of GDDR6X memory on a 384-bit bus, delivering 1.01 TB/s of bandwidth. The GPU’s boost clock is 2520 MHz, with a base clock of 2235 MHz. These numbers explain why 4K performance remains playable even at Ultra: 82.1 FPS is above the 60 FPS threshold, and 4K High at 106.1 FPS is smooth. The GPU’s 16,384 shading units and 128 RT cores are relevant for Lockdown Protocol’s FPS rendering, though the game is not ray-tracing heavy based on the measured data.

The RTX 4090’s memory clock is 1313 MHz (21 Gbps effective), which contributes to the 1.01 TB/s bandwidth. This bandwidth is critical at 4K, where the 24 GB frame buffer allows high-resolution textures without swapping. The data shows that at 4K Low, the GPU still produces 176.1 FPS, indicating that even at the lowest preset, the GPU’s raw compute (82.58 TFLOPS FP32) is not fully utilized — the CPU is likely the constraint at 1080p Low (231.9 FPS) and 1440p Low (209.1 FPS). The GPU’s 91st percentile ranking among all GPUs is consistent with its performance, but the measured FPS in Lockdown Protocol suggest the game is more CPU-sensitive at lower resolutions.

Settings Recommendations

The measured data indicates that Medium settings offer the best balance of performance and visual quality. At 1080p Medium, the combo delivers 204.1 FPS, which is close to the Low preset’s 231.9 FPS but with better visuals. At 1440p Medium, the average is 188.3 FPS, still well above 144 Hz refresh rates. At 4K Medium, the average is 126.1 FPS, which is a significant improvement over High (106.1 FPS) and Ultra (82.1 FPS). For users with 1440p monitors, Medium is the sweet spot: 188.3 FPS is 13% higher than High (166.5 FPS) and 49% higher than Ultra (126.4 FPS).

High settings are viable for 1080p and 1440p, with 195.9 FPS and 166.5 FPS respectively, but at 4K High the average drops to 106.1 FPS, which may be below the refresh rate of high-end 4K displays. Ultra settings are only recommended for 1080p, where 174.1 FPS is still competitive, but at 1440p Ultra (126.4 FPS) and 4K Ultra (82.1 FPS), the visual gains diminish relative to the FPS cost. The data suggests that Low settings are unnecessary for this combo, as even 4K Low (176.1 FPS) exceeds the refresh rate of most monitors. Therefore, Medium is the recommended preset for most users, with High as a fallback for those prioritizing image quality at 1080p or 1440p.

CPU Role

The Intel Core i5-11400F has 6 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its 12 MB of shared L3 cache and dual-channel DDR4 memory (51.2 GB/s bandwidth) are modest by current standards, but the benchmark results show it does not bottleneck the RTX 4090 at 4K. The CPU’s 3DMark scores are telling: 5,619 in the 16-thread test and 868 in the single-thread test. In Cinebench R23, it scores 14,372 multi-core and 2,029 single-core. These numbers place the i5-11400F at the 75th percentile among all CPUs, with an average benchmark score of 17,181.

The CPU’s nearest rivals in average score are the AMD Ryzen 7 5700U (17,189, 0% delta) and Intel Core i7-1260P (17,212, -0.2% delta). This indicates the i5-11400F is competitive with mid-range mobile processors, but in a desktop FPS game like Lockdown Protocol, the six cores are sufficient for 4K gaming. The measured FPS at 4K Low (176.1 FPS) versus 4K Ultra (82.1 FPS) shows that the CPU can push high frame rates when the GPU is not heavily loaded. However, at 1080p Low (231.9 FPS), the CPU may be nearing its limit, as the GPU could theoretically render more frames. The combo’s rank of 119 out of 1,637 suggests that other CPUs paired with the RTX 4090 achieve higher FPS, likely due to higher single-thread performance or more cores.

Measured FPS Breakdown

At 1920x1080, the combo achieves 231.9 FPS on Low, 204.1 FPS on Medium, 195.9 FPS on High, and 174.1 FPS on Ultra. The spread from Low to Ultra is 57.8 FPS, or a 25% reduction. At 2560x1440, the figures are 209.1 FPS (Low), 188.3 FPS (Medium), 166.5 FPS (High), and 126.4 FPS (Ultra). The drop from Low to Ultra at 1440p is 82.7 FPS, or 40%. At 3840x2160, the results are 176.1 FPS (Low), 126.1 FPS (Medium), 106.1 FPS (High), and 82.1 FPS (Ultra). The reduction from Low to Ultra at 4K is 94.0 FPS, or 53%.

Resolution scaling is consistent: moving from 1080p to 1440p reduces FPS by 10% at Low, 8% at Medium, 15% at High, and 27% at Ultra. Moving from 1440p to 4K reduces FPS by 16% at Low, 33% at Medium, 36% at High, and 35% at Ultra. These percentages show that the Low preset is least affected by resolution, while Ultra is most affected. The data also shows that at each resolution, Medium provides a substantial FPS advantage over High: at 1080p, Medium is 4% faster than High; at 1440p, Medium is 13% faster; at 4K, Medium is 19% faster. The only setting where the combo dips below 100 FPS is 4K Ultra (82.1 FPS), while all other configurations exceed 100 FPS. This breakdown confirms that the RTX 4090 is the primary driver of performance, with the i5-11400F providing adequate support across all tested resolutions and presets.
