Downfall

# Downfall Performance Analysis: AMD Ryzen 5 2600 + NVIDIA GeForce RTX 3080 Ti

This combination pairs a 2018 six-core Zen-based processor with a 2021 Ampere flagship GPU, creating a notable generational gap that manifests clearly in Downfall's measured frame rates. The data reveals a system where the GPU frequently operates below its potential, particularly at lower resolutions where the CPU's architectural limitations become the primary constraint. Across all tested configurations, the combo ranks 1090th out of 3716 total combinations tested, placing it in the upper third of all systems while demonstrating that the processor holds back the graphics card in specific scenarios.

Resolution Scaling

The measured FPS progression from 1080p to 4K reveals a classic CPU-bound pattern at lower resolutions that gradually shifts toward GPU limitation at higher pixel counts. At 1080p with Ultra settings, the system delivers 130 FPS, but dropping to Low settings only increases this to 250 FPS—a 92% gain that seems substantial until examining the 1440p numbers. At 2560x1440, the same Low-to-Ultra spread spans from 222 FPS down to 93 FPS, while at 4K the range tightens to 138 FPS at Low versus 58 FPS at Ultra.

The scaling behavior tells a compelling story about where the bottleneck resides. Moving from 1080p Low (250 FPS) to 1440p Low (222 FPS) costs only 11% performance, while the jump from 1440p Low to 4K Low (138 FPS) demands a 38% reduction. This pattern suggests that at 1080p and even 1440p, the AMD Ryzen 5 2600's six cores and twelve threads are saturated before the RTX 3080 Ti can reach its full rendering capacity. The GPU's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth only become the limiting factor when pixel throughput demands exceed what the processor can feed.

Ultra settings amplify this effect dramatically. The 1080p Ultra result of 130 FPS versus 1440p Ultra at 93 FPS represents a 28% drop for a 78% increase in pixel count—indicating that even at Ultra quality, the CPU still constrains performance. Only at 4K Ultra (58 FPS) does the system appear genuinely GPU-limited, as the 34.10 TFLOPS FP32 throughput and 186.5 GPixel/s pixel rate finally become the decisive factors. The data implies that users targeting high refresh rates below 4K will consistently encounter processor-induced ceilings.

CPU Role

The AMD Ryzen 5 2600 operates with a base clock of 3.40 GHz and boost clock of 3.90 GHz across six cores and twelve threads. Its Zen architecture, built on GlobalFoundries' 12 nm process with 4,800 million transistors, delivers a Passmark multithread score of 13,160 and single-thread score of 2,239. These synthetic benchmarks place the processor at the 75th percentile among all CPUs, with nearest rivals including the Intel Core Ultra 5 228V (0.2% faster) and Intel Xeon D-1746TER (0.7% faster).

In Downfall, the CPU's role becomes evident when examining the FPS gaps between settings at identical resolutions. At 1080p, the difference between Low (250 FPS) and Ultra (130 FPS) is a massive 120 FPS—a spread that cannot be attributed solely to GPU workload differences. This indicates that the Ryzen 5 2600's single-thread performance, reflected in its Geekbench single-core score of 1,154, struggles to maintain frame pacing when the GPU attempts to render frames as quickly as possible. The 16 MB shared L3 cache and dual-channel DDR4 memory support with 46.9 GB/s bandwidth provide adequate data flow, but the architecture's IPC limitations become apparent.

The processor's 65W TDP and unlocked multiplier suggest headroom for overclocking, yet the measured data shows the stock configuration already creates a bottleneck at 1080p Low. The Passmark physics score of 673 and integer math score of 44,518 provide context for how the CPU handles game logic and physics calculations, which in a horror title like Downfall may involve complex scripted sequences that tax single-thread performance. The 3.90 GHz boost clock appears insufficient to fully utilize the RTX 3080 Ti's capabilities below 4K resolution.

GPU Role

The NVIDIA GeForce RTX 3080 Ti represents the upper echelon of Ampere architecture, built on Samsung's 8 nm process with 28,300 million transistors across a 628 mm² die. Its 10,240 shading units, 320 TMUs, and 112 ROPs deliver 34.10 TFLOPS FP32 performance, while 80 RT cores and 320 tensor cores provide hardware acceleration for ray tracing and DLSS—features that Downfall may or may not utilize given its 2016 release date. The GPU's 12 GB GDDR6X memory operates across a 384-bit bus, achieving 912.4 GB/s bandwidth.

The benchmark results place this GPU at the 83rd percentile among all graphics cards, with an average benchmark score of 41,187. Its nearest rivals include the AMD Radeon Pro 5300 (0.8% slower) and NVIDIA GeForce RTX 5070 (2% slower), while the Tesla M40 variants score slightly higher. The Passmark G3D score of 26,896 and DirectX 12 score of 110 indicate strong DirectX 12 performance, which aligns with Downfall's likely rendering requirements.

The GPU's measured behavior in Downfall shows it waiting for the CPU at lower resolutions. At 4K Ultra, the 58 FPS result likely reflects the GPU's raw compute limits, but the 138 FPS at 4K Low demonstrates substantial headroom. The 186.5 GPixel/s pixel rate theoretically supports much higher frame rates, yet the system cannot exceed 250 FPS even at 1080p Low. The 1365 MHz base and 1665 MHz boost clocks provide consistent performance, while the 350W TDP and 750W suggested PSU indicate the power delivery necessary for sustained operation. The 12-pin power connector and dual-slot design suggest this card requires careful case planning.

How This Combo Ranks

With a combo rank of 1090 out of 3,716 tested combinations, this pairing sits in the 71st percentile of all systems evaluated in Downfall. This placement is notably lower than what the GPU's individual 83rd percentile ranking might suggest, confirming that the Ryzen 5 2600 drags down overall system performance. The gap between the CPU's 75th percentile and the combo's effective position highlights how processor limitations disproportionately affect gaming outcomes.

The ranking implies that approximately 2,626 tested combinations outperform this setup, which likely include systems with newer mid-range processors paired with similar or lesser GPUs. The data suggests that users seeking improved Downfall performance should prioritize CPU upgrades over GPU changes, as the RTX 3080 Ti already possesses capabilities the current processor cannot fully exploit. The 2,626 combinations ranked above this system likely benefit from processors with higher single-thread performance, which the measured FPS patterns indicate is the critical factor.

This rank also reflects the GPU's end-of-life production status, meaning no further driver optimizations are likely to close the gap. The combination's position among 3,716 total systems provides a realistic expectation for owners: competent 4K performance at reduced settings, but far from competitive at high refresh rates.

Measured FPS Breakdown

At 1920x1080, the system delivers 250 FPS on Low, 233 FPS on Medium (with min 198, max 268), 208 FPS on High, and 130 FPS on Ultra. The Medium preset's 198 FPS minimum represents the only recorded floor at this resolution, suggesting frame time consistency is acceptable but not stellar. The 120 FPS difference between Low and Ultra demonstrates the CPU's inability to maintain high frame rates when GPU workload increases.

At 2560x1440, performance scales to 222 FPS on Low, 182 FPS on Medium (min 154, max 209), 149 FPS on High, and 93 FPS on Ultra. The Medium settings show a 55 FPS spread between minimum and maximum, indicating some frame pacing variability. The 71% performance retention from 1080p to 1440p at Low settings (250 to 222 FPS) versus 72% at Ultra (130 to 93 FPS) shows consistent scaling behavior across quality levels.

At 3840x2160, the system achieves 138 FPS on Low, 113 FPS on Medium (min 96, max 130), 93 FPS on High, and 58 FPS on Ultra. The 4K Medium minimum of 96 FPS and maximum of 130 FPS reveal a 34 FPS range, suggesting the GPU is now becoming the primary constraint. The progression from 1080p Ultra (130 FPS) to 4K Ultra (58 FPS) represents a 55% performance loss, while the same resolution change at Low settings (250 to 138 FPS) costs 45%—indicating that higher settings amplify the GPU's workload more than the CPU's limitations.

Settings Recommendations

For 4K displays, the Medium preset at 3840x2160 delivers 113 FPS with a minimum of 96 FPS, providing the best combination of visual quality and smoothness. High settings at 93 FPS remain playable, but the Medium option's guaranteed minimum above 90 FPS makes it the more reliable choice. Ultra at 58 FPS should be avoided unless visual fidelity takes absolute priority over responsiveness.

For 1440p monitors, High settings at 149 FPS offer an excellent experience for both visual quality and speed. Medium at 182 FPS (min 154) provides additional headroom for competitive play, while Ultra at 93 FPS sacrifices too much performance for marginal visual gains. The 1440p Low setting at 222 FPS adds little benefit over Medium given the quality difference.

At 1080p, Medium settings at 233 FPS (min 198) represent the optimal configuration, delivering high refresh rate performance with better visuals than Low. High at 208 FPS remains viable, but the 25 FPS advantage of Medium makes it the preferred choice. Ultra at 130 FPS is not recommended, as it cuts performance nearly in half compared to High while offering minimal visual improvements in a horror game where darkness often hides detail. The data consistently shows Medium settings provide the best performance-to-quality ratio across all resolutions, with the minimum FPS figures confirming stable frame delivery.
