Downfall

Downfall is a 2016 horror title that stresses the GPU heavily at higher resolutions, and the combination of the AMD Ryzen 9 5900X with the NVIDIA GeForce GTX 1660 Ti produces a clear performance hierarchy across the measured settings. The data shows a system that is capable of smooth frame rates at 1080p, but which begins to struggle as resolution and graphical fidelity increase, with the GPU acting as the primary bottleneck in most scenarios.

Resolution Scaling

The measured FPS data reveals a steep performance drop as resolution increases from 1920x1080 to 3840x2160, indicating that the NVIDIA GeForce GTX 1660 Ti is the limiting component in this configuration. At Low settings, the average frame rate falls from 147 FPS at 1080p to 105 FPS at 1440p, a reduction of 42 FPS, and then further down to 65 FPS at 4K, representing a total loss of 82 FPS from the baseline. This scaling pattern is characteristic of a GPU that is being pushed to its limits by pixel count, rather than a CPU bottleneck, as the Ryzen 9 5900X has ample headroom in its 12 cores and 24 threads.

The trend continues across all settings presets. At High settings, the average drops from 99 FPS at 1080p to 70 FPS at 1440p, and then to 44 FPS at 4K. The Medium preset shows a similar trajectory: 120 FPS at 1080p, 86 FPS at 1440p, and 53 FPS at 4K. The Ultra preset is the most demanding, with averages of 62 FPS at 1080p, 44 FPS at 1440p, and a marginal 27 FPS at 4K. The consistent pattern of roughly a 30-40% reduction in frame rate when moving from 1080p to 1440p, and another significant drop at 4K, points directly to the GPU’s fill rate and memory bandwidth being the decisive factors.

The GTX 1660 Ti’s specifications support this interpretation. With a memory bus width of 192-bit and a bandwidth of 288.0 GB/s, the card is capable at 1080p but becomes increasingly strained as the pixel workload grows at higher resolutions. The 6 GB of GDDR6 memory is sufficient for the game’s demands, but the sheer number of pixels at 3840x2160 overwhelms the 48 ROPs and the 5.437 TFLOPS of FP32 compute power. The result is that at 4K, even the Low preset only manages an average of 65 FPS, which is below the 70 FPS threshold that many users consider the minimum for a smooth experience in a horror title where responsiveness matters for atmosphere.

Settings Recommendations

Based on the measured FPS data, the optimal balance between visual quality and performance for this hardware combination is the Medium preset at 1920x1080 resolution. At this setting, the system delivers an average of 120 FPS with a minimum of 102 FPS and a maximum of 138 FPS, providing a fluid experience that avoids the stutter that can break immersion in a horror game. The 102 FPS minimum is particularly important, as it indicates that even in demanding scenes, the frame rate does not dip below the refresh rate of most standard monitors.

For users with 1440p displays, the Low preset is the only viable option for maintaining high frame rates, delivering 105 FPS on average. The Medium preset at 1440p drops to 86 FPS with a minimum of 73 FPS, which is playable but may exhibit noticeable frame pacing issues in fast-paced sequences. The High preset at 1440p falls to 70 FPS, which is acceptable for a slower-paced horror game, but the Ultra preset at this resolution drops to 44 FPS, which is too low for a genre that relies on smooth motion to build tension.

At 4K resolution, the data shows that the GTX 1660 Ti is not well-suited for this game at high visual fidelity. The Low preset averages 65 FPS, which is the only setting that approaches playability, while Medium drops to 53 FPS and High falls to 44 FPS. The Ultra preset at 4K is effectively unplayable at 27 FPS. The recommendation for 4K users is to stick with the Low preset if frame rate is the priority, or to consider lowering the resolution to 1440p and using the Medium preset for a better balance of image quality and performance.

Measured FPS Breakdown

At 1920x1080, the system shows strong performance across all presets. The Low setting delivers the highest average at 147 FPS, followed by Medium at 120 FPS with a minimum of 102 FPS and a maximum of 138 FPS. The High preset averages 99 FPS, while Ultra drops to 62 FPS. This resolution is clearly where the GTX 1660 Ti is most comfortable, with even the most demanding preset remaining above the 60 FPS threshold.

Moving to 2560x1440, the performance degrades notably. The Low preset still manages a solid 105 FPS, but Medium falls to 86 FPS with a minimum of 73 FPS and a maximum of 99 FPS. The High preset averages 70 FPS, and Ultra drops to 44 FPS. This resolution represents a compromise for the hardware, where users must choose between high frame rates at Low settings or reduced visual quality at Medium to stay above 60 FPS.

At 3840x2160, the GPU is clearly overmatched. The Low preset averages 65 FPS, which is barely playable, while Medium drops to 53 FPS with a minimum of 45 FPS and a maximum of 61 FPS. The High preset falls to 44 FPS, and Ultra is essentially unplayable at 27 FPS. The data shows that 4K is not a viable resolution for this combination beyond the Low preset, and even that setting is borderline.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is the decisive component in this system’s Downfall performance. With a base clock of 1500 MHz and a boost clock of 1770 MHz, the card operates at frequencies that are typical for its generation, but its raw compute power of 5.437 TFLOPS is modest by modern standards. The 1536 shading units and 96 TMUs provide adequate pixel throughput for 1080p, but the 48 ROPs become a bottleneck at higher resolutions where the demand for fill rate increases exponentially.

The memory subsystem is another critical factor. The 6 GB of GDDR6 memory operates at 1500 MHz with a 192-bit bus, yielding a bandwidth of 288.0 GB/s. This is sufficient for Downfall’s textures at lower resolutions, but the data shows that the card’s performance drops by roughly 40% when moving from 1080p to 1440p, and another 40% from 1440p to 4K. This scaling is consistent with a memory bandwidth limitation, as the pixel data required at 4K exceeds what the 192-bit interface can efficiently feed to the GPU cores.

The GPU’s benchmark scores place it at the 41st percentile of all GPUs, with an average score of 7723. Its nearest rivals in the database are the AMD Radeon 540, which is 0.7% slower, and the AMD Radeon Pro WX 3100, which is 1.9% slower. The card’s DirectX 12 score of 51 and DirectX 11 score of 103 from Passmark indicate that it handles older APIs well, which aligns with Downfall’s 2016 release date and its likely use of DirectX 11. The GPU’s Turing architecture supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, ensuring compatibility with the game’s rendering pipeline.

CPU Role

The AMD Ryzen 9 5900X is far from being a bottleneck in this configuration. With 12 cores and 24 threads, the CPU provides massive parallel processing capability that is largely underutilized by Downfall, a horror game that likely relies on single-threaded performance for its core logic. The CPU’s base clock of 3.70 GHz and boost clock of 4.80 GHz ensure that even the most demanding single-threaded tasks are handled with ease, as evidenced by its 3DMark single-thread score of 941 and Cinebench R23 single-core score of 1527.

The CPU’s benchmark results show it is a top-tier performer, sitting at the 87th percentile of all CPUs with an average benchmark score of 41376. Its nearest rivals include the Intel Core Ultra 7 366H, which is 0.3% faster, and the Intel Core i7-14650HX, which is 0.5% faster. In multithreaded workloads, the Ryzen 9 5900X excels, with a Cinebench R23 multicore score of 16262 and a Geekbench multicore score of 14118. These scores indicate that the CPU has significant headroom for any background tasks or streaming workloads that might run alongside the game.

The CPU’s Zen 3 architecture, codenamed Vermeer, is built on a 7 nm process with 8,300 million transistors across two chiplets. The 64 MB of L3 cache is particularly beneficial for gaming, as it reduces memory latency and improves data access patterns. The dual-channel DDR4 memory support with a bandwidth of 51.2 GB/s is more than adequate for the GTX 1660 Ti’s PCIe 3.0 x16 interface, which is the GPU’s bus interface. In this system, the CPU’s role is to feed the GPU with data and handle game logic, and the measured FPS data shows that it performs this role without introducing any significant frame rate limitations. The CPU’s performance is evidenced by the fact that the frame rates scale consistently with GPU load, confirming that the GTX 1660 Ti is the sole determinant of performance in Downfall.
