Lockdown Protocol

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 3080 Ti delivers a high-refresh-rate experience in Lockdown Protocol, but the data reveals a clear hierarchy where the GPU dominates the workload. This combination ranks in the 73rd percentile of tested combos, placing it firmly in the upper tier for competitive play. The measured frame rates show that this system is capable of exceeding 240 FPS at lower settings, yet it also demonstrates the classic performance cliff when pushing maximum image quality at 4K.

Resolution Scaling

The transition from 1080p to 4K produces a steep, predictable drop in average frame rates across all settings. At High settings, the system delivers 160.9 FPS at 1920x1080, which falls to 117.5 FPS at 2560x1440, and further to 74.6 FPS at 3840x2160. This represents a 53.6% reduction in performance from 1080p to 4K, indicating that the GPU is the primary bottleneck as pixel count increases.

The scaling pattern becomes more aggressive at lower settings. At Low settings, the 1080p result of 259.8 FPS drops to 193 FPS at 1440p, and then to 120.5 FPS at 4K. The percentage drop from 1440p to 4K at Low settings is 37.6%, which is larger than the 26.9% drop seen when moving from 1080p to 1440p. This suggests that even at Low settings, the RTX 3080 Ti's compute resources are being saturated by the 4K resolution.

Ultra settings show the most pronounced scaling penalty. The 119.5 FPS at 1080p falls to 86.6 FPS at 1440p, and then to 58.3 FPS at 4K. The 4K Ultra result is barely above the 60 FPS threshold, meaning players seeking smooth gameplay at maximum quality will need to consider 1440p as their primary resolution. The data indicates that 1440p High is the sweet spot, offering 117.5 FPS, which is 57.5% higher than the 4K High result.

GPU Role

The RTX 3080 Ti's 12 GB of GDDR6X memory on a 384-bit bus provides 912.4 GB/s of bandwidth, which proves sufficient for Lockdown Protocol at all tested resolutions. The memory clock runs at 1188 MHz, translating to 19 Gbps effective, and this bandwidth headroom is evident in the relatively small performance gaps between Medium and High settings at each resolution.

The GPU's boost clock of 1665 MHz and base clock of 1365 MHz, combined with 10240 shading units, 320 TMUs, and 112 ROPs, deliver a raw compute throughput of 34.10 TFLOPS FP32. This architecture, built on Samsung's 8 nm process with 28,300 million transistors, produces a pixel rate of 186.5 GPixel/s and a texture rate of 532.8 GTexel/s. These specifications translate directly to the measured results: the GPU maintains a 44.6% advantage at 1080p Medium (185 FPS) over 4K Medium (87.2 FPS).

The GPU's benchmark scores corroborate its gaming performance. Its Passmark G3D score of 26896 and 3DMark Steel Nomad DX12 score of 5077 place it in the 83rd percentile of all GPUs.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 259.8 FPS, Medium reaches 185 FPS, High achieves 160.9 FPS, and Ultra drops to 119.5 FPS. The progression from Low to Ultra represents a 54% reduction in performance, but even the Ultra setting remains above 100 FPS, making 1080p a viable resolution for maximum quality.

At 2560x1440, the frame rates remain highly playable. Low settings yield 193 FPS, Medium produces 137.5 FPS, High maintains 117.5 FPS, and Ultra falls to 86.6 FPS. The step from High to Ultra is 30.9 FPS, which is the largest relative drop between any two adjacent settings at this resolution, suggesting that Ultra's additional effects are particularly demanding.

At 3840x2160, the system's limits become apparent. Low settings still manage 120.5 FPS, which is playable for competitive play. Medium drops to 87.2 FPS, High falls to 74.6 FPS, and Ultra bottoms out at 58.3 FPS. The 4K Low result is interesting because it outperforms the 1440p Ultra result by 33.9 FPS, indicating that resolution has a greater impact on performance than graphical settings in this title.

The full data set shows a consistent pattern: lowering resolution provides more headroom than lowering settings. Moving from 4K Ultra to 1080p Ultra yields a 61.2 FPS improvement, while moving from 4K Ultra to 4K Low yields a 62.2 FPS improvement. This suggests that Lockdown Protocol is heavily pixel-bound, and players should prioritize resolution scaling over setting adjustments when optimizing for frame rate.
