Downfall

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 2060 combination in Downfall delivers a playable experience across most settings, but the data reveals a system where the GPU is the primary bottleneck, especially at higher resolutions and quality presets. The RTX 2060, with its 6 GB of GDDR6 memory, struggles to maintain high frame rates when the visual load is maxed out, while the Ryzen 5 8400F’s six Zen 4 cores provide ample headroom for the game’s processing demands. This pairing is best suited for 1080p gaming, where it excels, but it requires careful settings management for 1440p and 4K displays.

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

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, which are strong figures for a desktop CPU in its class. While the CPU’s benchmark scores are not directly tied to Downfall’s frame rates, they establish its capability to handle modern game engines without becoming the limiting factor. The processor’s multi-threaded performance is solid, with a Cinebench R23 multi-core score of 20851 and a 3DMark max-threads score of 6165. This indicates that the CPU can manage the background tasks and game logic required by a horror title like Downfall without causing stutter or frame pacing issues.

The Ryzen 5 8400F’s single-thread performance is equally important for gaming. Its 3DMark single-thread score of 951 and Cinebench R23 single-core score of 2943 show that it has strong per-core performance, which is crucial for games that rely on a few heavily loaded threads. The CPU’s 16 MB of shared L3 cache and DDR5 memory support (with a bandwidth of 83.2 GB/s) further ensure that data can be fed to the GPU efficiently. In the context of Downfall’s measured results, the CPU’s role is to keep up with the GPU’s demands. At 1080p Low settings, where the GPU is less stressed, the CPU’s performance allows the system to reach 175.9 FPS, demonstrating that it is not a bottleneck in this scenario. Given that the Ryzen 5 8400F sits at the 82nd percentile of all CPUs, it is a capable partner for the RTX 2060.

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

The NVIDIA GeForce RTX 2060 is the clear performance limiter in this pairing. It features 6 GB of GDDR6 memory on a 192-bit bus, providing 336.0 GB/s of bandwidth. The GPU’s base clock is 1365 MHz with a boost clock of 1680 MHz. While these specifications are adequate for 1080p gaming, the 6 GB VRAM capacity becomes a significant constraint at higher resolutions and with Ultra settings. The data shows a dramatic drop in performance when moving from Medium to Ultra at 4K: the average FPS falls from 65.1 to 31.6, a decrease of over 50%. This suggests that the GPU is running out of memory or hitting its compute limits when the texture and shading demands increase.

The RTX 2060’s benchmark scores place it at the 58th percentile of all GPUs, with an average benchmark score of 16074. Its nearest rivals, such as the AMD Radeon RX 7600S, are within a 0.5% performance delta, indicating that it is a mid-range card by modern standards. In Downfall, the GPU’s performance scales predictably with settings. At 1080p High, it achieves 120 FPS, but at 4K Ultra, it drops to 31.6 FPS. This pattern is typical for a GPU with 6 GB of VRAM, as higher resolutions and settings require more memory bandwidth and capacity. The GPU’s 1920 shading units and 120 TMUs are sufficient for the game’s visual effects at lower presets, but they are overwhelmed at the highest quality levels.

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

The resolution scaling data provides clear evidence of GPU-bound performance. Moving from 1080p to 4K at the same settings results in substantial FPS drops, which is expected when the GPU is the limiting factor. At High settings, the average FPS drops from 120 at 1080p to 84.9 at 1440p, and then to 50.2 at 4K. This represents a 58% reduction in performance from 1080p to 4K. The pattern is similar at Medium settings, where frame rates fall from 140.3 at 1080p to 104.1 at 1440p and 65.1 at 4K.

The most telling data point is at Low settings. At 1080p Low, the system achieves 175.9 FPS, which is a very high frame rate. However, at 4K Low, this drops to 77.1 FPS. Even at the lowest settings, the GPU cannot maintain high frame rates at 4K, confirming that it is the primary bottleneck. If the CPU were the limiting factor, we would expect to see less of a drop when lowering the resolution, as the CPU’s workload does not change significantly with resolution. The fact that FPS scales almost linearly with the number of pixels indicates that the RTX 2060’s rendering capabilities are being fully utilized, and it simply cannot keep up with the demands of 4K rendering in Downfall.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system performs admirably across all presets. Low settings yield an average of 175.9 FPS, which is excellent for a horror game that may benefit from high refresh rates. Medium settings drop to 140.3 FPS, still very smooth. High settings achieve 120 FPS, which is the target for many gamers. Ultra settings, however, show a significant drop to 72.4 FPS, indicating that the RTX 2060’s 6 GB VRAM is being stressed with the highest quality textures and effects.

At 2560x1440, the performance is still playable but requires compromises. Low settings average 124.2 FPS, which is good. Medium settings drop to 104.1 FPS, and High settings fall to 84.9 FPS. Ultra settings dip below 60 FPS, with an average of 49.6 FPS, making them less desirable for a smooth experience. The jump from 1080p to 1440p reduces performance by roughly 30%, which is consistent with the increased pixel count.

At 3840x2160, the GPU is clearly overmatched. Low settings average 77.1 FPS, which is playable but not ideal. Medium settings drop to 65.1 FPS, and High settings fall to 50.2 FPS. Ultra settings are nearly unplayable, with an average of 31.6 FPS. The combination of the RTX 2060’s compute power and 6 GB VRAM is insufficient for 4K gaming in Downfall, forcing users to choose between low settings for playable frame rates or higher settings with significant performance hits.

FAQ

Q: Is the Ryzen 5 8400F a bottleneck at 1080p Low settings?

A: No. The system reaches 175.9 FPS at 1080p Low, indicating that the CPU has sufficient headroom to feed the GPU, which is the limiting factor at this resolution.

Q: What happens to performance when switching from High to Ultra at 1440p?

A: The average FPS drops from 84.9 at High to 49.6 at Ultra, a reduction of approximately 42%. This makes Ultra settings impractical for a smooth experience at 1440p.

Q: Does the CPU’s multi-threaded performance matter for this game?

A: The Ryzen 5 8400F’s multi-threaded scores (e.g., Cinebench R23 multi-core of 20851) show it can handle background tasks, but the game’s frame rates are more dependent on the GPU, as evidenced by the large FPS drops when resolution increases.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this system is at 1080p with High settings, which delivers an average of 120 FPS. This provides a smooth, responsive experience that is well-suited for a horror game where immersion and reaction time are important. If a higher frame rate is preferred, dropping to Medium settings at 1080p yields 140.3 FPS, a 17% improvement with a minor visual quality reduction. Low settings at 1080p offer the highest frame rate at 175.9 FPS, which is useful for competitive play or if the user has a high-refresh-rate monitor, but the visual quality is significantly reduced.

For 1440p users, the best balance is achieved at Medium settings, which averages 104.1 FPS. This is above the 60 FPS threshold and provides a good visual experience without overburdening the GPU. High settings at 1440p are also playable, with an average of 84.9 FPS, but the drop to 49.6 FPS at Ultra is too severe to recommend. At 4K, the only viable option is Low settings, which averages 77.1 FPS. Medium settings at 4K drop to 65.1 FPS, and anything higher results in sub-60 FPS performance, which is not ideal for a smooth gameplay experience. Users should avoid Ultra settings at all resolutions, as the performance cost is too high relative to the visual gains, particularly given the GPU’s 6 GB VRAM limitation.
