Downfall

Resolution Scaling

Downfall shows a predictable but steep resolution penalty with this AMD pairing. Moving from 1920x1080 to 2560x1440 at Ultra settings drops average FPS from 82.9 to 58.7, a 24.2 FPS loss that represents a 29% reduction in frame rate. The step from 1440p to 4K at Ultra is even more punishing: 58.7 FPS falls to 38.4 FPS, a 34.6% decline. This scaling pattern indicates the Radeon RX 6600 XT becomes the primary limiting factor as pixel count rises, particularly at the highest preset.

The Low settings curve tells a different story. At 1080p Low, the system produces 192.8 FPS average. Dropping to 1440p Low still yields 138.6 FPS, and 4K Low maintains 84.8 FPS. The performance retention from 1080p to 4K at Low (44% of the original frame rate) versus at Ultra (46% retention) is similar, but the absolute headroom at Low means the game remains very playable even at 4K. The 4K Low result of 84.8 FPS is actually higher than the 1080p Ultra result of 82.9 FPS, showing that settings choice matters more than resolution alone in this title.

Medium settings occupy the middle ground with 157.9 FPS at 1080p, 110.8 FPS at 1440p, and 70.8 FPS at 4K. The scaling efficiency here — 70% retention from 1080p to 1440p and 45% from 1080p to 4K — suggests the GPU's 8 GB frame buffer and 256.0 GB/s memory bandwidth handle the intermediate preset without severe bottlenecks. High settings land at 128.6 FPS, 90.7 FPS, and 58.5 FPS for the three resolutions respectively.

The data indicates that the 4K Ultra result of 38.4 FPS is the only configuration that falls below the 40 FPS threshold, making it marginal for smooth gameplay. All other measured combinations exceed 58 FPS, which means the CPU and GPU pairing can deliver acceptable performance across most of the tested spectrum.

GPU Role

The AMD Radeon RX 6600 XT sits at the 71st percentile among all GPUs in the database, with an average benchmark score of 27985. Its nearest rivals include the NVIDIA GeForce GTX 980 Ti (deltaPct 0.1%), the AMD Radeon R9 M395X (deltaPct 0.4%), and the NVIDIA GeForce RTX 3070 (deltaPct -0.9%). These deltas are remarkably small, placing the RX 6600 XT in a tightly contested performance band where a few percentage points separate it from both older and newer competitors.

The card's specifications include 8 GB of GDDR6 memory on a 128-bit bus, producing 256.0 GB/s of bandwidth. Its boost clock reaches 2589 MHz with a game clock of 2359 MHz, and the base clock sits at 1968 MHz. The FP32 compute throughput is 10.60 TFLOPS, and the card features 2048 shading units, 128 TMUs, and 64 ROPs. These specifications explain the measured FPS patterns: the card has enough raw throughput for high frame rates at lower resolutions, but the 128-bit memory interface constrains performance as resolution increases and texture demands grow.

In Downfall specifically, the GPU's role becomes evident when comparing Ultra versus Low settings. At 1080p, the gap between Low (192.8 FPS) and Ultra (82.9 FPS) is 109.9 FPS, indicating that the card's shading units and ROPs are heavily taxed by the higher preset's effects. The 4K Ultra result of 38.4 FPS aligns with the card's position relative to the RTX 3070, which is only 0.9% faster in aggregate benchmarks — both cards would struggle with this game's most demanding configuration at 4K.

The RX 6600 XT's 32 ray accelerators are present but Downfall's horror genre typically relies more on traditional rasterization than ray tracing. The card's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility ensure modern rendering paths are available, but the measured data shows that raw fill rate and memory bandwidth are the decisive factors in this game.

FAQ

Q: Can this system run Downfall at 4K?

A: Yes, but with caveats. At 4K Low settings, the average FPS is 84.8, which is smooth. At 4K High, it drops to 58.5 FPS, and at 4K Ultra, only 38.4 FPS is achieved. For consistent 60+ FPS at 4K, Low or Medium settings are required.

Q: What is the best resolution for competitive play?

A: At 1080p, even Ultra settings produce 82.9 FPS, while Low reaches 192.8 FPS. For maximum frame rates, 1080p Low offers the highest measured average. If you need high refresh rates, 1080p Medium at 157.9 FPS or High at 128.6 FPS are strong options.

Q: How does the RX 6600 XT compare to the RTX 3070 in this game?

A: The aggregate benchmark data shows the RTX 3070 is only 0.9% faster than the RX 6600 XT on average. Given that the RX 6600 XT's measured FPS in Downfall ranges from 38.4 to 192.8 depending on settings, the RTX 3070 would likely produce results within a few frames per second of these figures.

Q: Is the Ryzen 5 8400F holding back the GPU?

A: The CPU's benchmark data suggests it has ample headroom. Its multithreaded score of 24530 in Passmark and single-thread score of 3684 indicate strong processing power. At 1080p Low, the system reaches 192.8 FPS, which suggests the GPU is the primary limiter even at lower resolutions.

Q: What settings provide the most balanced experience at 1440p?

A: Medium settings at 2560x1440 deliver 110.8 FPS, which is the best combination of visual quality and performance in the measured data. High settings at 90.7 FPS are also viable, while Ultra drops to 58.7 FPS, still playable but with diminishing returns.

Q: How does the 4K Medium result compare to 1080p Ultra?

A: The 4K Medium average of 70.8 FPS is lower than the 1080p Ultra average of 82.9 FPS, but the gap is only 12.1 FPS. This suggests that the GPU handles the resolution increase better at Medium settings than the settings increase at 1080p, making 4K Medium a reasonable alternative to 1080p Ultra.

Measured FPS Breakdown

At 1920x1080, the full settings spectrum shows the GPU's capabilities and limits. Low settings produce 192.8 FPS average, Medium reduces this to 157.9 FPS, High drops further to 128.6 FPS, and Ultra bottoms out at 82.9 FPS. The step from High to Ultra costs 45.7 FPS, the largest single-settings penalty at this resolution, indicating that Ultra's additional effects place a heavy load on the RX 6600 XT.

Moving to 2560x1440, the frame rates shift downward across all presets. Low still delivers a strong 138.6 FPS, Medium follows at 110.8 FPS, High achieves 90.7 FPS, and Ultra manages 58.7 FPS. The relative ordering remains consistent, but the gap between Low and Ultra narrows to 79.9 FPS from the 109.9 FPS gap seen at 1080p. This compression suggests that at higher resolutions, the GPU's pixel throughput becomes the dominant constraint, reducing the impact of settings changes.

At 3840x2160, the pattern continues with more pronounced degradation. Low settings yield 84.8 FPS, Medium drops to 70.8 FPS, High falls to 58.5 FPS, and Ultra produces 38.4 FPS. The difference between Low and Ultra at 4K is 46.4 FPS, similar in absolute terms to the 1080p High-to-Ultra gap. The 4K results show that Medium and High settings are closely grouped (70.8 vs 58.5 FPS), while Ultra trails significantly, reinforcing that the Ultra preset's demands exceed what the card can comfortably deliver at this resolution.

The data set lacks minimum and maximum FPS values, so the analysis relies on averages. However, the consistency of the scaling across resolutions and settings suggests stable performance without severe frame-time spikes in the measured configurations.

Settings Recommendations

For 1920x1080 displays, Ultra settings at 82.9 FPS provide a fully playable experience with maximum visual quality. If you prioritize higher frame rates for a high-refresh monitor, High at 128.6 FPS is the sweet spot, delivering 45.7 FPS more than Ultra while maintaining strong visual fidelity. Medium at 157.9 FPS is the choice for competitive play where every frame matters, and Low at 192.8 FPS is only for those chasing absolute maximum FPS.

At 2560x1440, Medium settings at 110.8 FPS offer the best balance between visual quality and performance. This preset retains 78% of the Low settings frame rate while providing substantially better graphics. High at 90.7 FPS is a solid alternative if you prefer higher fidelity and your display is 60-75 Hz. Ultra at 58.7 FPS is playable but close to the edge, so it is only recommended if you have a 60 Hz monitor and want maximum detail.

For 3840x2160, Low settings at 84.8 FPS are the only configuration that provides comfortable headroom above 60 FPS. Medium at 70.8 FPS is still smooth and represents the best visual quality for 4K gaming with this hardware. High at 58.5 FPS is borderline but acceptable for slower-paced horror gameplay, while Ultra at 38.4 FPS should be avoided unless you accept sub-40 FPS performance.

The overall recommendation based on measured data is to use Medium settings at any resolution. This preset delivers 157.9 FPS at 1080p, 110.8 FPS at 1440p, and 70.8 FPS at 4K, all of which exceed the 60 FPS threshold for smooth gameplay. High settings are viable at 1080p and 1440p but fall short at 4K. Ultra settings are only recommended at 1080p.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor from the 8000 series, based on Zen 4 architecture with the Phoenix codename. It operates at a 4.20 GHz base clock and boosts to 4.70 GHz, with a 65 W TDP. The chip sits at the 82nd percentile among all CPUs in the database, with an average benchmark score of 25064.

Benchmark results show strong multi-threaded performance: Cinebench R23 multicore reaches 20851 points, while the single-core score is 2943. Passmark multithread scores 24530, and the 3DMark 16-thread test produces 6091 points. These figures place the 8400F in a competitive position, with nearest rivals including the AMD Ryzen 7 2700X (deltaPct 0%), the AMD Ryzen AI 5 PRO 340 (deltaPct -0.1%), and the AMD Ryzen 5 7500F (deltaPct 0.3%). The negligible percentage differences indicate that the 8400F trades blows with these processors within a fraction of a percent.

In Downfall, the CPU's role appears secondary to the GPU, but the data supports this conclusion. At 1080p Low, the system achieves 192.8 FPS, which is high enough that the CPU could become a factor if the GPU were faster. The processor's 16 MB of shared L3 cache and 83.2 GB/s memory bandwidth with DDR5 support provide adequate data throughput for the game's horror environments, which typically feature modest object counts and limited simulation complexity compared to open-world titles.

The 3DMark single-thread score of 951 and Passmark single-thread score of 3684 indicate strong per-core performance, which matters for games like Downfall that may not fully utilize 12 threads. The Cinebench R15 single-core score of 296 reinforces this. The CPU's boost clock of 4.70 GHz ensures that single-threaded workloads receive sufficient clock speed, and the 4 nm process node from TSMC with 25,000 million transistors on a 178 mm² die contributes to efficient power delivery within the 65 W envelope.

Given that the GPU's nearest rival comparisons show only 0.9% differences with the RTX 3070, and the CPU's rival deltas are all within 0.3%, this pairing represents a balanced mid-range configuration. The measured FPS results suggest that the GPU is the limiting component in most scenarios, particularly at higher resolutions and settings, while the CPU has sufficient headroom to avoid bottlenecking the RX 6600 XT in Downfall.
