Downfall

Downfall is a 2016 horror title that stresses the GPU heavily, and the measured data for the AMD Ryzen 9 5950X with the AMD Radeon RX 6600 XT shows a clear trade-off between visual fidelity and frame rate. The benchmark results indicate that the card can deliver playable performance at most settings, but the demands of the Ultra preset at higher resolutions are significant. This analysis walks through the measured frames per second (FPS) to determine the optimal settings, the role of the GPU and CPU, and how the system scales across resolutions.

Settings Recommendations

The measured FPS data reveals that the High preset offers the most balanced experience across all tested resolutions. At 1920x1080, the High preset delivers an average of 130.7 FPS, which is a substantial 47.7 FPS higher than the Ultra preset's 83 FPS at the same resolution. The performance gap between High and Ultra is consistent: at 2560x1440, High achieves 92.9 FPS while Ultra drops to 57.5 FPS, and at 3840x2160, High manages 59.8 FPS versus Ultra's 36.5 FPS. The data suggests that the Ultra preset imposes a heavy rendering load that the RX 6600 XT cannot sustain smoothly, particularly at 4K where the frame rate falls below the 60 FPS threshold.

The Medium preset provides a solid middle ground for users prioritizing higher frame rates over visual fidelity. At 1920x1080, Medium achieves 159.2 FPS, which is 28.5 FPS higher than High. This advantage persists at 2560x1440, where Medium delivers 112.5 FPS compared to High's 92.9 FPS, and at 3840x2160, Medium reaches 66.3 FPS versus High's 59.8 FPS. For a horror game where smooth motion can be critical to the experience, the Medium preset at 2560x1440 offers the best combination of image quality and performance, as it stays comfortably above 100 FPS while still providing a richer visual experience than Low.

The Low preset functions as a performance maximizer, yielding the highest frame rates at every resolution. The jump from Low to Medium is notable: at 1920x1080, Low produces 193.3 FPS while Medium yields 159.2 FPS, a difference of 34.1 FPS. This gap narrows at higher resolutions, with a 22.6 FPS difference at 2560x1440 and a 19.1 FPS difference at 3840x2160. Given the diminishing returns in visual quality, the Low preset is only recommended for users with high-refresh-rate 1080p displays seeking maximum responsiveness. For most scenarios, the High preset at 1920x1080 or the Medium preset at 2560x1440 provides the best measured experience.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, and its performance in Downfall is directly tied to its memory subsystem and clock speeds. The card features 8 GB of GDDR6 memory on a 128-bit bus, delivering a bandwidth of 256.0 GB/s. This memory configuration appears sufficient for the game's demands, as the frame rates scale predictably with resolution and settings rather than showing signs of a memory capacity bottleneck.

The GPU's clock speeds are notably high, with a base clock of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz. These clocks contribute to the card's raw computational throughput, which includes 10.60 TFLOPS of FP32 performance and a pixel rate of 165.7 GPixel/s. The measured FPS data shows that the RX 6600 XT can handle Downfall's High preset at 2560x1440 with an average of 92.9 FPS, indicating that the GPU's shader and texture processing capabilities are well-suited for this title. The card's 2048 shading units and 128 texture mapping units work in tandem with the 64 render output units, which are likely the limiting factor at the Ultra preset where the frame rate drops to 57.5 FPS at 2560x1440.

In the broader market context, the RX 6600 XT holds a 71st percentile rank among all GPUs, with an average benchmark score of 27985. Its nearest rival, the NVIDIA GeForce GTX 980 Ti, scores 27956, a delta of just 0.1%, indicating near-identical overall performance. The data shows that the RX 6600 XT trails the NVIDIA GeForce RTX 3070 by 0.9% in average score, which suggests that in Downfall, the RX 6600 XT's frame rates should be comparable to that competitor. The 8 GB VRAM capacity is sufficient for the game's textures at all tested settings, as evidenced by the playable frame rates at 4K with the High preset.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the frame rates range from 83 FPS on Ultra to 193.3 FPS on Low. The Medium preset achieves 159.2 FPS, while High reaches 130.7 FPS. This resolution offers the widest performance spread, with a 110.3 FPS difference between the lowest and highest settings.

At 2560x1440, the frame rates scale down predictably. The Low preset delivers 135.1 FPS, followed by Medium at 112.5 FPS, High at 92.9 FPS, and Ultra at 57.5 FPS. The performance drop from 1080p to 1440p is consistent across settings, with the Low preset losing 58.2 FPS, Medium losing 46.7 FPS, High losing 37.8 FPS, and Ultra losing 25.5 FPS. This pattern indicates that the GPU is the primary performance driver, as the frame rate reduction is proportional to the increase in pixel count.

At 3840x2160, the frame rates become more constrained. The Low preset maintains 85.4 FPS, which is still playable, while Medium drops to 66.3 FPS and High to 59.8 FPS. The Ultra preset falls to 36.5 FPS, which is below the threshold for smooth gameplay. The data shows that the RX 6600 XT can handle 4K in Downfall, but only with lowered settings. The High preset at 4K is borderline, with an average of 59.8 FPS that would be acceptable for a less demanding genre but may feel insufficient for a horror title where quick reactions are necessary.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 represents a fourfold increase in pixel count, and the measured FPS data shows how the RX 6600 XT responds to this load. At the High preset, the frame rate drops from 130.7 FPS at 1080p to 92.9 FPS at 1440p, a 37.8 FPS reduction, and then to 59.8 FPS at 4K, a further 33.1 FPS reduction. The total drop from 1080p to 4K is 70.9 FPS, which represents a 54.2% reduction in performance.

The scaling is more pronounced at the Low preset, where the frame rate falls from 193.3 FPS at 1080p to 135.1 FPS at 1440p and then to 85.4 FPS at 4K. This represents a total reduction of 107.9 FPS, or 55.8%, from the lowest to highest resolution. The consistency of these percentage drops across settings suggests that the GPU is the limiting component, as the CPU's performance remains constant regardless of resolution.

The data indicates that the RX 6600 XT's memory bandwidth of 256.0 GB/s and 8 GB of VRAM are sufficient to handle the increased data throughput at 4K, as the frame rates remain playable at Medium and High settings. The 128-bit memory bus does not appear to create a severe bottleneck, as the performance scaling is roughly linear with pixel count. The Ultra preset shows the most significant degradation, with a 46.5 FPS drop from 1080p to 4K, which suggests that the additional shading and texture work at Ultra settings pushes the GPU's compute resources to their limits.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, operating on the AMD Socket AM4 platform. Its base clock of 3.40 GHz and boost clock of 4.90 GHz provide substantial single-threaded performance, as evidenced by its Cinebench R23 single-core score of 5450. The multi-core score of 38607 in the same test demonstrates the processor's ability to handle heavily threaded workloads, though Downfall, as a horror game, likely does not utilize all 32 threads.

The CPU's benchmark results place it in the 93rd percentile of all CPUs, with an average benchmark score of 49062. Its nearest rival, the Intel Core i5-14600K, scores 49166, a delta of -0.2%, indicating nearly identical overall performance. The Ryzen 9 5950X also outperforms the Intel Xeon Gold 5318H by 0.7% and trails the AMD EPYC 4345P by 1.1%. These scores confirm that the CPU is not the limiting factor in Downfall, as the measured FPS data shows frame rates that are consistent with GPU-bound performance.

The processor's 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide ample data throughput for game logic and asset streaming. The measured frame rates at 1080p, where CPU bottlenecks typically manifest, show that the Ryzen 9 5950X can maintain high FPS across all settings, with the Low preset reaching 193.3 FPS. This indicates that the CPU can feed the GPU sufficiently, and any performance limitations in Downfall are attributable to the RX 6600 XT's rendering capabilities rather than the processor's processing power.
