Lockdown Protocol

The AMD Ryzen 5 5600F and NVIDIA GeForce GTX 1660 Ti combination delivers a playable but constrained experience in Lockdown Protocol, with performance that scales predictably with resolution and settings. The pairing is clearly GPU-limited at higher resolutions, while the CPU provides sufficient headroom at 1080p. This analysis breaks down the measured data, contextualizes the combo's standing, and offers concrete settings guidance based on the recorded frame rates.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and reveals a classic GPU-bound scenario. At High settings, the average frame rate falls from 76 FPS at 1920x1080 to 56 FPS at 2560x1440, a reduction of roughly 26%. Pushing further to 3840x2160 drops the average to 36 FPS, which is a 53% decrease compared to the 1080p result. This pattern indicates that the GTX 1660 Ti's rendering throughput is the primary bottleneck as pixel count increases.

The scaling at Low settings is even more pronounced. The average at 1080p is 122 FPS, which is an excellent result for competitive play. At 1440p, the average drops to 90 FPS, a 26% reduction. At 4K, the average plummets to 58 FPS, which is a 52% loss from the 1080p baseline. The fact that the Low preset at 4K (58 FPS) is nearly identical to the High preset at 1440p (56 FPS) suggests that the GPU is saturated regardless of the graphical complexity; the resolution alone dictates the upper bound of performance.

The Medium preset data provides the clearest view of the scaling curve. Across the three resolutions, the averages are 87 FPS (1080p), 64 FPS (1440p), and 41 FPS (4K). The jump from 1080p to 1440p costs 23 FPS, while the jump from 1440p to 4K costs another 23 FPS. This linear degradation is a hallmark of a graphics card that is running out of fillrate and memory bandwidth as the render target expands. The GTX 1660 Ti's 192-bit memory bus and 288.0 GB/s bandwidth are simply insufficient to feed the pixel pipeline at 4K, making the resolution the single most important factor in determining playability.

How This Combo Ranks

In the grand scheme of tested hardware combinations, this pairing sits in the lower half of the database. The combo ranks 2441 out of 2828 tested combinations, placing it in the 14th percentile of all systems evaluated in Lockdown Protocol. This low ranking is consistent with the components' individual standings: the CPU is in the 85th percentile of all processors, while the GPU is in the 41st percentile of all graphics cards. The system's overall performance is dragged down by the GPU, which is the limiting factor in this title.

The GPU's nearest rivals illustrate its position. The GTX 1660 Ti has an average benchmark score of 7723, which is only 0.7% higher than the AMD Radeon 540 (7673). It is 1.9% ahead of the AMD Radeon Pro WX 3100 (7580) and 2.2% ahead of the AMD Radeon R7 250 (7557). These are extremely tight margins, indicating that the GTX 1660 Ti is not a dominant performer in its class. The Intel Arc A310 is a mere 2.3% behind, showing that even entry-level modern GPUs are competitive with this older card.

The CPU, however, is a much stronger component. With an average benchmark score of 36945, it is essentially tied with the Intel Core Ultra 5 225 (36938, 0% delta) and the AMD Ryzen 5 5500X3D (37018, -0.2% delta). This places the Ryzen 5 5600F in a solid mid-range position for processing power. The data suggests that in Lockdown Protocol, the CPU is rarely the bottleneck; the GTX 1660 Ti is what prevents this combo from achieving higher frame rates and a better ranking.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is a Turing-architecture GPU built on a 12 nm process at TSMC. It features 1536 shading units, 96 texture mapping units, and 48 ROPs. Its clock speeds are rated at a base of 1500 MHz and a boost of 1770 MHz. The card's memory subsystem consists of 6 GB of GDDR6 on a 192-bit bus, yielding a bandwidth of 288.0 GB/s. These specifications align with its performance profile: adequate for 1080p gaming but limited for higher resolutions.

In Lockdown Protocol, the 6 GB VRAM capacity is a potential concern at higher settings. While no VRAM usage data is provided, the FPS drops at 4K Ultra (27 FPS) and 4K High (36 FPS) suggest that the memory capacity and bandwidth are being taxed. The card's pixel rate is 84.96 GPixel/s and its texture rate is 169.9 GTexel/s, which are respectable figures for its generation but not sufficient to handle the demands of 4K rendering at high detail levels.

The GTX 1660 Ti's compute capabilities are modest by modern standards, with an FP32 performance of 5.437 TFLOPS. This limits its ability to handle advanced shading and post-processing effects at high resolutions. The benchmark results reflect this: the PassMark G3D score is 12871, and the DirectX 12 score is only 51. These low-level scores correlate with the measured FPS in Lockdown Protocol, where the card struggles to maintain high frame rates at 4K. The card is end-of-life, which means no further driver optimizations are likely, but its performance in this game is predictable and consistent with its hardware class.

Measured FPS Breakdown

The measured data provides a complete picture of performance across all settings and resolutions. At 1920x1080, the card delivers its best results. The Low preset achieves an average of 122 FPS, which is ideal for high-refresh-rate monitors. The Medium preset averages 87 FPS, with a minimum of 74 FPS and a maximum of 100 FPS, ensuring smooth gameplay. The High preset averages 76 FPS, and the Ultra preset averages 57 FPS. All 1080p settings are playable, with even the most demanding Ultra preset staying above 60 FPS on average.

At 2560x1440, the performance drops but remains mostly acceptable. The Low preset averages 90 FPS, which is still very smooth. The Medium preset averages 64 FPS, with a minimum of 54 FPS and a maximum of 73 FPS, indicating some frame time variance but overall playability. The High preset averages 56 FPS, which dips below the 60 FPS threshold. The Ultra preset averages 42 FPS, which is not ideal for a fast-paced FPS game. This resolution represents the edge of the card's comfort zone, requiring users to drop settings to maintain high frame rates.

At 3840x2160, the card is clearly out of its depth. The Low preset averages 58 FPS, which is technically playable but not smooth. The Medium preset averages 41 FPS, with a minimum of 35 FPS and a maximum of 47 FPS, resulting in noticeable stuttering. The High preset averages 36 FPS, and the Ultra preset averages 27 FPS. These results are below the threshold for competitive play, and even casual play would be hampered by the low frame rates. The data shows that 4K is not a viable resolution for this combo in Lockdown Protocol.

Settings Recommendations

Based on the measured FPS, the optimal settings depend on the user's display and performance priorities. For 1080p users, the Medium preset offers the best balance. The 87 FPS average is well above the 60 FPS standard, and the minimum of 74 FPS ensures that frame drops are rare. The High preset also works well at 76 FPS, but the Medium preset provides a larger safety margin for intense combat scenarios. The Low preset is the best choice for esports-focused players who want to maximize frame rates, as it delivers 122 FPS.

For 1440p users, the Low preset is the only setting that guarantees a consistently smooth experience, with a 90 FPS average. The Medium preset is acceptable for most players, with a 64 FPS average and a 54 FPS minimum, but it may result in occasional hitches during heavy action. The High and Ultra presets are not recommended, as they average 56 FPS and 42 FPS respectively, which are too low for a responsive FPS experience. Users with 144Hz monitors should definitely stick to Low settings to get the most out of their display.

For 4K users, the data is clear: this card cannot deliver a satisfactory experience at this resolution. The Low preset's 58 FPS average is the only playable option, but it is still below the 60 FPS ideal. The Medium preset's 41 FPS average and 35 FPS minimum will cause noticeable stuttering. The High and Ultra presets are effectively unplayable. If a 4K display is a must, users should consider lowering the resolution scaling or accepting that the game will run at less than 60 FPS. The best experience, per the data, is to run the game at 1080p or 1440p with Low or Medium settings.

FAQ
