Downfall

The AMD Ryzen 7 3700X and NVIDIA GeForce GTX 1660 Ti pairing delivers a playable but dated experience in Downfall, a 2016 horror title. The benchmark data shows this combo sits near the bottom of the pack, ranking 3202 out of 3716 tested configurations. This is a system that can handle the game at lower resolutions and settings, but it struggles to maintain high frame rates at 4K or with Ultra presets.

Resolution Scaling

The performance drop from 1080p to 4K is steep and clearly exposes the GPU as the primary bottleneck. At Low settings, the average frame rate falls from 147 FPS at 1920x1080 to 105 FPS at 2560x1440, a 28.6% reduction. Moving further to 3840x2160, the average drops to 65 FPS, which is a 55.8% decline from the 1080p baseline. This scaling pattern is typical for a GPU that is running out of pixel-pushing capability as resolution increases.

The High settings preset shows a similar, though slightly less dramatic, trend. The average frame rate goes from 99 FPS at 1080p, down to 70 FPS at 1440p, and finally to 44 FPS at 4K. The drop from 1440p to 4K is a 37.1% reduction, indicating that the GTX 1660 Ti's 6 GB of VRAM and 192-bit memory bus are being saturated by the higher pixel count and texture demands.

The data suggests that the CPU is not the limiting factor at any resolution. The Ryzen 7 3700X, with its 8 cores and 16 threads, provides ample headroom. The frame rate differences between resolutions are far too large to be attributed to CPU limitations. This is a GPU-bound scenario across the board, with the GTX 1660 Ti's performance ceiling being hit well before the CPU's capabilities are exhausted.

GPU Role

The GTX 1660 Ti is a Turing-architecture GPU built on a 12 nm process, featuring 1536 shading units and 48 ROPs. Its boost clock of 1770 MHz and 6 GB of GDDR6 memory on a 192-bit bus provide a memory bandwidth of 288.0 GB/s. These specifications explain its mid-range standing, as its benchmark score of 12871 in Passmark G3D places it in the 41st percentile of all GPUs. The data shows it is closely matched with the AMD Radeon 540, which is only 0.7% ahead, and the Intel Arc A310, which trails by 2.3%.

In Downfall, the GPU's VRAM capacity and bandwidth are the key constraints at higher settings. At 4K Ultra, the average frame rate collapses to 27 FPS, a 58.5% drop from the already-low 65 FPS at 4K Low. This massive penalty suggests that the Ultra preset is demanding far more memory bandwidth and fill rate than the card can provide, likely causing texture streaming and memory allocation overhead. The GPU's FP32 performance of 5.437 TFLOPS is simply insufficient for the most demanding settings.

The card's DirectX 12 performance is notably weak, with a Passmark DX12 score of just 51. This is significantly lower than its DirectX 11 score of 103, which could indicate driver overhead or architectural limitations in this specific API. This is relevant because Downfall may be utilizing a DirectX 12 render path, and the data suggests the GTX 1660 Ti is not well-optimized for it, contributing to the poor performance at high settings.

CPU Role

The AMD Ryzen 7 3700X is a Zen 2 architecture processor with 8 cores and 16 threads, clocked at a base of 3.60 GHz and a boost of 4.40 GHz. Its multi-threaded performance is solid, scoring 22458 in Passmark's multithread test and 2092 in Cinebench R15 multi-core. This level of performance places it in the 84th percentile of all CPUs, making it a strong pairing for a mid-range GPU from a processing standpoint.

Benchmark results show the 3700X is a very capable processor. Its Passmark single-thread score of 2656 and Geekbench single-core score of 1593 are respectable for its generation. In terms of overall average benchmark score, it sits at 34260, which is statistically tied with rivals like the AMD Ryzen AI 7 350 and Intel Core i5-13450HX, showing a delta of just 0.1% and -0.2% respectively. This indicates the CPU's processing power is not a weak link in this system.

The CPU's role in Downfall appears to be secondary. Given the GPU-bound nature of the performance scaling, the 3700X is never the primary constraint. Even at 1080p Low, where the GPU is working least, the CPU is able to feed it enough data to achieve 147 FPS. The 32 MB of L3 cache and dual-channel DDR4 memory support are more than adequate for this title's demands, ensuring the GTX 1660 Ti is the sole performance limiter.

Measured FPS Breakdown

At 1920x1080, the GTX 1660 Ti delivers playable frame rates across most presets. Low settings produce an average of 147 FPS, which is exceptionally smooth. Medium settings yield 120 FPS, with a minimum of 102 FPS and a maximum of 138 FPS, indicating stable performance. High settings bring the average down to 99 FPS, still well above the 60 FPS threshold for most displays. Ultra settings are the exception, with the average dropping to 62 FPS, which is playable but shows a significant performance hit.

Moving to 2560x1440, the performance becomes more constrained. Low settings still provide a high average of 105 FPS. Medium settings offer 86 FPS, with a range of 73 to 99 FPS, which is a solid experience. High settings drop the average to 70 FPS, which is acceptable for most players. Ultra settings, however, fall to 44 FPS, making the game feel less fluid and potentially problematic for fast-paced sections.

At 3840x2160, the GTX 1660 Ti is clearly out of its depth. Low settings manage an average of 65 FPS, which is borderline playable. Medium settings drop to 53 FPS, with a minimum of 45 FPS, which will result in noticeable stuttering. High settings fall to 44 FPS, and Ultra settings become nearly unplayable at 27 FPS. The data indicates that 4K is not a viable resolution for this combo, even with settings turned down.

How This Combo Ranks

The combination of the Ryzen 7 3700X and GTX 1660 Ti ranks 3202 out of 3716 tested combos in Downfall. This places it in the bottom 13.8% of all systems tested, which is a poor result for a horror game that typically relies on atmosphere and tension rather than fast-paced action. This low ranking is primarily due to the GPU's limitations. While the CPU is a strong performer in its own right, the GTX 1660 Ti's 41st percentile GPU score drags the entire system down.

This ranking is consistent with the GPU's rival data. The GTX 1660 Ti is essentially tied with the AMD Radeon 540, which is only 0.7% faster, and the AMD Radeon Pro WX 3100, which is 1.9% slower. These are all entry-level or older mid-range cards, and their performance in a 2016 title like Downfall is expected to be limited. The system's overall benchmark score of 34260 for the CPU and 7723 for the GPU confirms this is a balanced but low-end pairing for modern gaming.

The data suggests that this combo is not well-suited for Downfall at high resolutions or settings. The 3202nd rank out of 3716 indicates that a majority of other tested systems will provide a better experience. For a game released in 2016, this is a disappointing result, showing that the GTX 1660 Ti, despite being a capable 1080p card, struggles with the game's higher-end presets.

Settings Recommendations

For the best experience, the 1920x1080 resolution is the clear choice. The data shows that at 1080p, the High preset provides an average of 99 FPS, which is smooth and visually appealing. If a higher frame rate is desired, the Medium preset offers 120 FPS with a minimum of 102 FPS, ensuring no drops below the refresh rate of a standard 60 Hz monitor. Low settings at 147 FPS are only recommended for competitive play or if the user has a high-refresh-rate display.

At 2560x1440, the Medium preset is the best balance of visual quality and performance, yielding 86 FPS. The High preset at 70 FPS is also viable, but the Medium preset's minimum of 73 FPS provides a more consistent experience. The Low preset at 105 FPS is an option for players prioritizing frame rate over fidelity, but the High preset is still within acceptable bounds.

The 3840x2160 resolution is not recommended for this hardware. Even at Low settings, the average of 65 FPS is marginal, and the Medium preset's minimum of 45 FPS will cause noticeable hitches. The Ultra preset at 27 FPS is unplayable. Users with a 4K display should either lower the resolution to 1440p or consider a GPU upgrade. The data indicates that the Ultra preset is not worth the significant performance cost at any resolution, as the jump from High to Ultra results in a 37.4% performance drop at 1080p, from 99 FPS to 62 FPS.

Ultimately, the sweet spot for this combo is 1080p with High settings, offering a solid 99 FPS average. For those wanting to push to 1440p, Medium settings are the optimal choice to maintain a fluid experience. Avoid 4K and the Ultra preset entirely, as the hardware cannot handle the demands.
