Downfall

Resolution Scaling

The measured FPS data for Downfall with the AMD Ryzen 5 3600 and AMD Radeon RX 6600 XT shows a clear pattern of resolution-dependent performance scaling. At 1920x1080 with Low settings, the combo delivers 189.4 FPS, which drops to 133.8 FPS at 2560x1440, and further to 86.1 FPS at 3840x2160. This progression represents a 29.3% reduction from 1080p to 1440p, and a 54.5% reduction from 1080p to 4K at Low settings. The scaling is consistent with a GPU-bound workload at lower resolutions, where the RX 6600 XT's 2048 shading units and 128-bit memory interface become the primary constraint.

At Medium settings, the same resolution progression shows 155.5 FPS at 1080p, 111 FPS at 1440p, and 66.6 FPS at 4K. The percentage drops are similar to Low settings, indicating that the GPU remains the limiting factor even as settings increase. However, the Ultra preset tells a different story: 81.9 FPS at 1080p falls to 58 FPS at 1440p (a 29.2% drop) and then to 37.3 FPS at 4K (a 54.5% drop from 1080p). The fact that the relative scaling remains nearly identical across all presets suggests the RX 6600 XT is consistently the bottleneck, rather than the CPU.

The delta between Low and Ultra at each resolution reveals the cost of maximum quality: at 1080p, Ultra is 107.5 FPS lower than Low; at 1440p, the gap narrows to 75.8 FPS; at 4K, it shrinks to 48.8 FPS. This narrowing gap at higher resolutions is a classic sign of pixel-throughput saturation — as the GPU becomes increasingly overwhelmed by resolution, the additional cost of higher settings diminishes proportionally. The data indicates that for players targeting 60 FPS or higher, 4K is only viable at Low settings (86.1 FPS), while Medium at 4K (66.6 FPS) remains playable but with less headroom.

Settings Recommendations

The measured rows provide a clear hierarchy for optimizing the experience in Downfall. The 3840x2160 Ultra preset produces 37.3 FPS, which is below the commonly accepted 60 FPS threshold for smooth gameplay. Dropping to High at 4K raises the average to 58.7 FPS, still marginally under 60 but close enough for most players to perceive as fluid, especially in a horror title where frame pacing matters less than visual atmosphere. Medium at 4K (66.6 FPS) provides a 12.8% improvement over High while maintaining a solid visual quality baseline. Low at 4K (86.1 FPS) is the only preset that offers substantial headroom, making it the recommended choice for 4K displays where competitive frame rates are prioritized.

At 2560x1440, the situation improves considerably. High delivers 93.8 FPS, which is well above the 60 FPS target and provides a balanced experience between fidelity and fluidity. Ultra at 1440p (58 FPS) sits just below the 60 FPS mark, making High the better choice for consistent performance. Medium at 1440p (111 FPS) and Low (133.8 FPS) are both excellent for high-refresh-rate displays, but the visual degradation from High to Medium is noticeable in a horror game where lighting and shadow quality contribute to atmosphere. The sweet spot at 1440p is High, offering nearly 94 FPS while retaining most of the visual features that matter.

For 1920x1080, all presets exceed 80 FPS, with Ultra at 81.9 FPS being the worst-case scenario. High at 127.2 FPS and Medium at 155.5 FPS both provide excellent experiences, but Ultra is the recommended preset for players with 1080p displays who want maximum visual fidelity without sacrificing playability. The 81.9 FPS at Ultra is comfortably above the 60 FPS threshold and leaves enough overhead for occasional drops. Low at 189.4 FPS is only relevant for esports-style play or extremely high refresh rate monitors, as the visual penalty is substantial. The data shows that at 1080p, the RX 6600 XT has enough headroom to run Ultra settings without compromising the experience.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. Its 32 MB of shared L3 cache and 3,800 million transistors on a 7 nm process node provide solid gaming performance, as reflected in its 76th percentile ranking among all CPUs. The benchmark data shows a 3dmark_single_thread score of 696, which is modest compared to newer architectures, but the multi-threaded scores (3dmark_16_threads at 4605) indicate that the CPU can handle multiple background tasks while gaming.

In Downfall, a horror title from 2016, the CPU's role appears secondary to the GPU at all tested resolutions. The fact that FPS scaling with resolution is nearly identical across presets — approximately 29% drop from 1080p to 1440p and 54% drop from 1080p to 4K — suggests the Ryzen 5 3600 is not the limiting factor. If the CPU were constrained, we would expect to see smaller FPS differences between resolutions, as the GPU would be waiting on the CPU at lower resolutions. Instead, the consistent scaling pattern points to the RX 6600 XT as the bottleneck.

The CPU's nearest rivals include the Intel Core i5-11400 with an average score of 18150 (0.1% higher), the AMD Ryzen 5 7535HS at 18101 (0.2% lower), and the AMD Ryzen 5 1600 at 18158 (0.2% higher). These tiny deltas indicate that the Ryzen 5 3600 is squarely in the middle of its performance tier. For a game like Downfall, which launched in 2016 and does not demand excessive thread counts, the 6-core/12-thread configuration provides ample headroom. The CPU's 3dmark_2_threads score of 1361 and 3dmark_4_threads score of 2579 show that even lightly threaded workloads are handled efficiently, which is typical for older game engines.

The 65 W TDP and dual-channel DDR4 memory support (51.2 GB/s bandwidth) are adequate for this pairing. The PCIe Gen 4, 16 Lanes interface ensures the GPU can communicate with the CPU without bandwidth limitations, although the RX 6600 XT is configured for PCIe 4.0 x8, which is still sufficient. In summary, the Ryzen 5 3600 provides a stable foundation that allows the RX 6600 XT to express its full performance potential in Downfall, with no evidence of CPU-induced frame drops or stuttering in the measured data.

How This Combo Ranks

The combination of the AMD Ryzen 5 3600 and AMD Radeon RX 6600 XT ranks 1256 out of 1741 tested combos in Downfall. This places it in the 27.8th percentile of all combinations, meaning roughly 72% of tested systems deliver higher average FPS. The rank reflects the GPU's position in the market: the RX 6600 XT has a 71st percentile ranking among all GPUs, and its nearest rivals include the NVIDIA GeForce GTX 980 Ti (avg score 27956, 0.1% lower) and the NVIDIA GeForce RTX 3070 (avg score 28238, 0.9% higher). The GPU's average benchmark score of 27985 is competitive with these cards, yet the combo rank suggests that the game's engine may favor other hardware configurations.

The CPU's 76th percentile ranking is higher than the GPU's 71st percentile, indicating that the processor is relatively stronger than the graphics card in this pairing. This imbalance could explain why the combo ranks lower than the sum of its parts might suggest — the CPU has more headroom than the GPU can utilize in this game. The nearest rival combos would likely feature similarly positioned CPUs with slightly stronger GPUs, pushing them higher in the rankings. For context, the RTX 3070, which scores 0.9% higher in GPU benchmarks, would likely produce a meaningfully better combo rank in a GPU-bound title like Downfall.

It is important to note that the combo rank of 1256 out of 1741 is based on actual measured FPS data, not synthetic benchmarks. This means the ranking reflects real-world performance in Downfall specifically, accounting for the game's engine quirks, optimization levels, and the interaction between the CPU and GPU. The fact that the combo sits below the median suggests that while this pairing is capable of delivering playable frame rates at most settings and resolutions, it is not at the top of the performance hierarchy for this particular title. Players considering this combo should expect solid but not exceptional performance, with the understanding that higher-end GPUs would yield better results in Downfall.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values across settings are as follows: Low produces 189.4 FPS, Medium produces 155.5 FPS, High produces 127.2 FPS, and Ultra produces 81.9 FPS. The progression from Low to Medium represents a 17.9% drop, from Medium to High an 18.2% drop, and from High to Ultra a 35.6% drop. The largest performance penalty occurs when moving from High to Ultra, which suggests that the Ultra preset enables significantly more demanding effects such as advanced shadows, reflections, or post-processing.

At 2560x1440, the measured values are: Low at 133.8 FPS, Medium at 111 FPS, High at 93.8 FPS, and Ultra at 58 FPS. The percentage drops from Low to Medium (17.0%) and Medium to High (15.5%) are similar to 1080p, but the High to Ultra drop is more severe at 38.2%. This indicates that the Ultra preset's additional features become more costly at higher resolutions, as the GPU is already working harder to fill more pixels.

At 3840x2160, the measured values are: Low at 86.1 FPS, Medium at 66.6 FPS, High at 58.7 FPS, and Ultra at 37.3 FPS. The Low to Medium drop is 22.6%, Medium to High is 11.9%, and High to Ultra is 36.5%. The Medium to High gap narrows at 4K compared to lower resolutions, likely because the GPU is already saturated and the incremental cost of High effects is less pronounced relative to the overall workload. The Ultra preset at 4K falls below 40 FPS, making it unsuitable for most players.

Comparing across resolutions, the 1080p Low result of 189.4 FPS is 2.2 times higher than the 4K Low result of 86.1 FPS. At Ultra, the 1080p result of 81.9 FPS is 2.2 times higher than the 4K result of 37.3 FPS. This consistent 2.2x scaling factor across all settings confirms that the RX 6600 XT's performance scales predictably with pixel count, and that the game's rendering pipeline does not introduce resolution-specific bottlenecks. The data overall shows that this combo is best suited for 1080p and 1440p gaming, with 4K being viable only at lower settings.
