Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 9 5900X + AMD Radeon RX 6750 XT

The AMD Ryzen 9 5900X paired with the AMD Radeon RX 6750 XT delivers a broadly playable Lockdown Protocol experience across all tested resolutions, though the character of that experience shifts dramatically depending on where you land on the settings spectrum. At 1080p, this combo is capable of triple-digit frame rates at every preset, while 4K demands more careful settings selection to stay above 60 FPS. The data reveals a system that is firmly GPU-limited at higher resolutions, with the CPU's substantial 12-core, 24-thread configuration providing ample headroom even at lower settings where frame rates climb steeply.

Resolution Scaling

The measured FPS data shows a clear and consistent pattern of performance degradation as resolution increases, which is typical for a GPU-bound scenario. At Low settings, the average frame rate drops from 200 FPS at 1920x1080 to 147 FPS at 2560x1440, a reduction of 53 FPS, and then further to 95 FPS at 3840x2160, representing a cumulative drop of 105 FPS from 1080p to 4K. This scaling behavior indicates that the Radeon RX 6750 XT's rendering throughput is the primary constraint as pixel count rises.

The Medium preset tells a similar story: 142 FPS at 1080p falls to 104 FPS at 1440p and then to 67 FPS at 4K. The percentage drop from 1080p to 1440p is roughly 27%, while the drop from 1440p to 4K is approximately 36%, showing that the performance penalty accelerates at higher resolutions. This nonlinear scaling suggests that memory bandwidth and fill-rate limitations become more pronounced as the pixel workload increases, consistent with the GPU's 192-bit memory bus and 432.0 GB/s bandwidth.

At High settings, the frame rates are 124 FPS at 1080p, 91 FPS at 1440p, and 59 FPS at 4K. The 4K result sits just below the 60 FPS threshold, indicating that High is borderline at that resolution. Ultra settings push the GPU even harder: 93 FPS at 1080p, 68 FPS at 1440p, and 44 FPS at 4K. The 44 FPS average at 4K Ultra is the only configuration in the entire dataset that falls below 60 FPS, making it the clear outlier in terms of playability.

The resolution scaling data strongly suggests that the limiting component at 1080p is not the CPU, given the massive frame rates achieved, but rather the GPU's ability to sustain high output. The Ryzen 9 5900X, with its 12 cores and 24 threads running at a boost clock of 4.80 GHz, is unlikely to bottleneck at these frame rates. Instead, the RX 6750 XT's 2,560 shading units and 64 ROPs are the determining factors, with the GPU's pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s directly influencing how quickly each resolution's pixel workload can be completed.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, fabricated on a 7 nm process at TSMC. Its clock speeds are notably high for the segment, with a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. These aggressive clocks, combined with 12 GB of GDDR6 memory on a 192-bit bus, give the card substantial raw throughput. The memory operates at 2250 MHz, translating to 18 Gbps effective and yielding a bandwidth of 432.0 GB/s.

In Lockdown Protocol, the GPU's role is clearly dominant across all tested configurations. The scaling from Low to Ultra at each resolution demonstrates how the card's compute resources are taxed by increasing graphical fidelity. At 1080p Low, the card produces 200 FPS, but this drops to 93 FPS at Ultra, a reduction of over 53%. This indicates that the game's Ultra preset introduces significant shading and texture workloads that consume the GPU's FP32 throughput of 13.31 TFLOPS.

The 12 GB VRAM capacity is worth noting in the context of this game. At 4K Ultra, the card still maintains a 44 FPS average, which suggests that memory capacity is not a limiting factor at these settings, as the GPU would likely exhibit severe frame drops or stuttering if it were running out of memory. The 192-bit bus and 432.0 GB/s bandwidth appear sufficient for the data demands of Lockdown Protocol at 4K, though the frame rate drop from Medium to Ultra at that resolution (67 to 44 FPS) highlights how bandwidth-intensive the Ultra preset is.

The GPU's benchmark scores place it at the 71st percentile among all GPUs, with an average benchmark score of 26,011. Its nearest rivals in synthetic testing are the AMD Radeon R9 M395X (0.5% slower), AMD FirePro W7100 (0.6% slower), AMD FirePro D700 (0.7% slower), and NVIDIA GeForce RTX 3080 Ti Mobile (1.1% slower). These close margins in synthetic benchmarks do not directly translate to Lockdown Protocol performance, but they do indicate that the RX 6750 XT sits in a competitive performance tier.

Settings Recommendations

For players targeting 60 FPS as a minimum, the data supports specific settings choices at each resolution. At 1920x1080, every preset delivers well above 60 FPS, with even the demanding Ultra preset averaging 93 FPS. This means 1080p users can freely select Ultra for maximum visual fidelity without sacrificing smoothness.

At 2560x1440, the High preset averages 91 FPS, while Ultra averages 68 FPS. Both comfortably exceed 60 FPS, but Ultra offers a more immersive experience at the cost of 23 FPS. For competitive play where higher frame rates are beneficial, High is the recommended choice, as it maintains 91 FPS while still providing substantial visual quality over Medium's 104 FPS baseline.

At 3840x2160, the settings selection becomes more critical. The Medium preset averages 67 FPS with a min FPS of 57 and max of 77, which is the only 4K configuration that consistently stays near or above 60 FPS. High averages 59 FPS, which may be acceptable for some players but risks dropping below 60 in demanding scenes. Ultra at 4K averages 44 FPS, which is likely too low for smooth gameplay in a fast-paced FPS. The recommendation for 4K is Medium, as it provides the best balance of visual quality and playable frame rates.

For players who prioritize frame rate above all else, the Low preset at 1080p delivers 200 FPS, which would be ideal for high-refresh-rate monitors. At 1440p, Low delivers 147 FPS, still excellent for 144 Hz displays. The Low preset at 4K averages 95 FPS, which is remarkably high for 4K and indicates that the game scales well even at lower quality settings.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are as follows: Low settings produce 200 FPS, Medium produces 142 FPS with a min of 121 and max of 164, High produces 124 FPS, and Ultra produces 93 FPS. The spread from Low to Ultra is 107 FPS, showing that the preset selection has a massive impact on performance at this resolution.

At 2560x1440, the averages are 147 FPS for Low, 104 FPS for Medium (min 89, max 120), 91 FPS for High, and 68 FPS for Ultra. The difference between Low and Ultra here is 79 FPS, a smaller absolute gap than at 1080p but still significant. The Medium preset's min FPS of 89 indicates that even in demanding scenes, frame rates remain high.

At 3840x2160, the averages are 95 FPS for Low, 67 FPS for Medium (min 57, max 77), 59 FPS for High, and 44 FPS for Ultra. The Medium preset is the only one with reported min/max values, showing a range of 57 to 77 FPS. This 20 FPS variance suggests some scene-to-scene variability at 4K, but the average remains playable.

The data reveals a consistent pattern across resolutions: the gap between Low and Medium is substantial (58 FPS at 1080p, 43 FPS at 1440p, 28 FPS at 4K), while the gap between Medium and High is smaller (18 FPS at 1080p, 13 FPS at 1440p, 8 FPS at 4K). The gap between High and Ultra is similar in magnitude (31 FPS at 1080p, 23 FPS at 1440p, 15 FPS at 4K). This suggests that Medium to High is the most efficient upgrade path in terms of frame rate cost.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, codenamed Vermeer, and manufactured on TSMC's 7 nm process. It features a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a 64 MB L3 cache and dual-channel DDR4 memory support. Its passmark multithread score of 39,002 and Cinebench R23 multicore score of 16,262 demonstrate strong multi-threaded performance, placing it at the 87th percentile among all CPUs.

In Lockdown Protocol, the CPU's role appears to be secondary to the GPU, based on the frame rate data. At 1080p Low, the system achieves 200 FPS, which would require the CPU to feed the GPU with draw calls and game logic at a very high rate. The 12 cores and 24 threads provide ample parallelism for the game's FPS genre demands, which typically include physics, AI, and network processing.

The CPU's single-thread performance, as measured by a passmark single-thread score of 3,469 and 3dmark single-thread score of 941, is also robust, ensuring that the game's main thread is not a bottleneck. The boost clock of 4.80 GHz on a single core provides the high-frequency responsiveness that FPS games often require.

The CPU's memory bandwidth of 51.2 GB/s over dual-channel DDR4 is adequate for the game's data demands, though it is lower than what newer platforms might offer. The 64 MB L3 cache is generous and helps reduce memory latency, which can be beneficial in fast-paced gameplay scenarios.

Given that frame rates scale so heavily with resolution and settings, the evidence points to the GPU being the primary constraint in this combo. The CPU's performance headroom is demonstrated by the fact that even at 4K Low, the system achieves 95 FPS, which is a frame rate that would stress many CPUs. The Ryzen 9 5900X's combination of high core count and high clock speeds ensures that it can keep up with the RX 6750 XT across the entire tested range of resolutions and settings.
