Downfall

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7600X is a 6-core, 12-thread processor built on the Zen 4 architecture (Raphael codename) using TSMC's 5 nm process. It operates with a base clock of 4.70 GHz and a boost clock of 5.30 GHz, backed by a 32 MB shared L3 cache and 1 MB L2 per core. The CPU's benchmark profile shows strong single-thread performance, with a 3DMark single-thread score of 1060 and a Cinebench R23 single-core score of 3406, both of which are critical for a horror title like Downfall where scene complexity and physics calculations often hinge on one or two primary threads.

In the measured frames, the CPU's role becomes clearer when examining the scaling between settings at 1080p. At Low settings, the combo achieves 151.9 FPS, while at Ultra it drops to 61 FPS. This 90.9 FPS spread at the same resolution indicates that the processor is not the limiting factor at lower settings—the GPU takes over as the bottleneck as settings increase. The Ryzen 5 7600X's multi-threaded capabilities, evidenced by a Cinebench R23 multicore score of 24128 and a PassMark multithread score of 28390, ensure that even at High settings (102 FPS at 1080p), the CPU maintains enough headroom to feed the GPU without stalling frame production.

The processor's 3DMark 16-thread score of 6879 versus its max-thread score of 6845 shows that the 12 threads are efficiently utilized, but the game does not appear to require extreme multi-threading. The 2-thread score of 2028 and 4-thread score of 3796 suggest that Downfall's workload is relatively light on core count, favoring the 7600X's high per-core clocks over additional cores. This is consistent with the CPU's 83rd percentile ranking among all CPUs, placing it well above average for gaming scenarios. The nearest rivals—AMD Ryzen 7 PRO 6850U, Ryzen 7 7735U, Ryzen 5 PRO 5655GE, and Ryzen 7 5700X—all sit within 0.2% of the 7600X's average benchmark score of 26272, but the 7600X's higher boost clock gives it an edge in latency-sensitive tasks typical of horror game rendering.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data provides a clear hierarchy of performance across presets. At 1920x1080, the Low preset delivers 151.9 FPS, which is more than sufficient for smooth gameplay, but it sacrifices visual fidelity that enhances the horror atmosphere—shadows, textures, and ambient effects. The Medium preset at 121.9 FPS offers a better balance, retaining 80% of the Low preset's frame rate while introducing moderate visual improvements. However, the High preset at 102 FPS is the sweet spot: it maintains a triple-digit frame rate while providing noticeably richer detail than Medium, and the 49.9 FPS difference between High and Low is a reasonable trade for the visual uplift.

At 2560x1440, the High preset drops to 69.6 FPS, which is still playable but begins to approach the threshold where frame pacing becomes noticeable in a horror title. The Medium preset at 85.8 FPS is the recommended choice for this resolution, as it offers over 16% more performance than High while still delivering decent visual quality. The Ultra preset at 48 FPS is too demanding for consistent smoothness, and Low at 103.8 FPS sacrifices too much atmosphere for marginal gains.

For 3840x2160, the situation shifts dramatically. High at 44.9 FPS and Medium at 55.6 FPS are both below the 60 FPS target, but Medium is the only viable option if visual fidelity matters—it provides 23.8% more performance than High. Low at 67.1 FPS is the only preset that achieves a comfortable frame rate at 4K, but it strips away the graphical detail that makes the horror environment immersive. Given the data, the best overall experience is the High preset at 1080p (102 FPS), which balances frame rate and visual quality without the compromises seen at higher resolutions.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound pattern. At High settings, the combo produces 102 FPS at 1080p, 69.6 FPS at 1440p (a 31.8% reduction), and 44.9 FPS at 4K (a 56% reduction from 1080p). This steep decline—more pronounced than the pixel count increase alone would suggest—indicates that the NVIDIA GeForce GTX 1660 Ti is the primary bottleneck. The GPU's 6 GB GDDR6 memory on a 192-bit bus with 288.0 GB/s bandwidth becomes increasingly strained as resolution climbs, and the 5.437 TFLOPS FP32 throughput cannot keep pace with the growing pixel workload.

At Low settings, the scaling is less severe: 151.9 FPS at 1080p, 103.8 FPS at 1440p (31.7% drop), and 67.1 FPS at 4K (55.8% drop). The relative consistency of these percentage drops across presets confirms that resolution scaling is dominated by the GPU's fill rate and memory bandwidth, not by the CPU. The Ryzen 5 7600X's role remains constant—it provides the same computational foundation regardless of resolution, and its high single-thread performance ensures that even at 4K Low (67.1 FPS), the CPU is not the limiting factor.

The gap between Low and High at 4K is 22.2 FPS (67.1 vs 44.9), while at 1080p the same gap is 49.9 FPS (151.9 vs 102). This narrowing at higher resolutions further underscores the GPU bottleneck: as pixel count increases, the GPU's fixed resources are consumed by rasterization, leaving less headroom for the additional shader work that High settings demand. The data clearly shows that the Ryzen 5 7600X has ample headroom even in the most demanding scenarios, while the GTX 1660 Ti's 12 nm Turing architecture, with its 1536 shading units and 48 ROPs, is the component that dictates frame rate ceilings.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 5 7600X and NVIDIA GeForce GTX 1660 Ti ranks 1488 out of 1741 tested combos in Downfall. This places it in the bottom 15% of all configurations, which is a striking result given the CPU's strong benchmark standing. The ranking reflects the GPU's modest position—the GTX 1660 Ti sits at the 55th percentile among all GPUs, with an average benchmark score of 13925. Its nearest rivals, including the AMD Radeon RX 570X (0.4% higher score) and NVIDIA RTX A2000 Mobile (0.8% higher), are all mid-range parts that similarly limit high-end CPUs.

The rank disparity between the CPU and GPU components is significant. The Ryzen 5 7600X's 83rd percentile CPU ranking is undermined by the GPU's 55th percentile, resulting in a combo that underperforms relative to what the processor could deliver with a more capable graphics card. In Downfall, the data shows that the combo's 1080p High score of 102 FPS is respectable, but the 4K Ultra score of 28.4 FPS is near-unplayable, highlighting how the GPU constrains the overall experience.

Within the ranking context, this combo sits alongside other pairings where a high-end CPU is paired with a mid-range GPU. The 1488th rank out of 1741 suggests that many other combinations—likely featuring stronger GPUs—achieve better frame rates in this game. The CPU's benchmark advantage over its nearest rivals (all within 0.2% in average score) does not translate into a higher combo rank because Downfall's performance is overwhelmingly GPU-limited across all measured resolutions and presets. For users with this specific pairing, the data indicates that upgrading the GPU would yield far greater performance gains than any CPU change.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture (TU116 chip) using TSMC's 12 nm process, with 6 GB of GDDR6 memory on a 192-bit bus delivering 288.0 GB/s bandwidth. Its base clock runs at 1500 MHz with a boost of 1770 MHz, and memory operates at 1500 MHz (12 Gbps effective). The GPU's 1536 shading units and 48 ROPs give it a pixel rate of 84.96 GPixel/s and a texture rate of 169.9 GTexel/s, with FP32 performance of 5.437 TFLOPS.

In Downfall, the GPU's VRAM capacity becomes a critical factor at higher resolutions and settings. At 4K Ultra, the combo achieves only 28.4 FPS, which is a 53.6% drop from 4K High (44.9 FPS). This severe degradation suggests that the 6 GB frame buffer is being exhausted at Ultra settings, forcing the GPU to manage memory more inefficiently. The 192-bit memory bus, while providing adequate bandwidth for 1080p, struggles to feed the shader units at 4K resolutions where texture and geometry data demands increase exponentially.

The GPU's DirectX 12 score of 51 in PassMark (versus 103 for DirectX 11) indicates that the architecture handles modern APIs less efficiently, which is relevant for a 2016 horror title that may not be fully optimized for newer rendering paths. The Vulkan score of 58014 and OpenCL score of 60863 in Geekbench suggest compute capabilities that are adequate but not exceptional, aligning with the GPU's 55th percentile ranking.

The GTX 1660 Ti's performance in Downfall is characterized by a sharp drop-off from Medium to Ultra settings at every resolution. At 1080p, Medium yields 121.9 FPS while Ultra yields 61 FPS—a 50% reduction. At 1440p, the same settings produce 85.8 FPS and 48 FPS respectively (44% reduction). At 4K, Medium achieves 55.6 FPS while Ultra falls to 28.4 FPS (49% reduction). This consistent pattern indicates that the GPU's shading units and ROPs are the limiting factor at Ultra settings, while the VRAM and bandwidth constrain performance at higher resolutions. The GPU's end-of-life production status and 120 W TDP suggest it was designed for 1080p gaming, and the data confirms that Downfall is best experienced at 1080p High (102 FPS) or 1440p Medium (85.8 FPS) with this card.
