Downfall

Resolution Scaling

The measured FPS data for Downfall with the Intel Core i5-12600KF and NVIDIA GeForce RTX 4080 reveals a clear scaling pattern as resolution increases. At 1080p with Ultra settings, the combo delivers 168 FPS. Moving to 1440p drops that to 120 FPS, a 28.6% reduction, while 4K Ultra falls further to 74 FPS, which is 55.9% below the 1080p figure. This steep decline at higher resolutions points to the GPU becoming the primary limiting factor as pixel count rises.

The scaling story changes dramatically when examining Low settings. At 1080p Low, the system produces 400 FPS, which drops to 285 FPS at 1440p (a 28.8% decrease) and 178 FPS at 4K (a 55.5% decrease from 1080p). The similarity in percentage drops between Low and Ultra settings across resolutions suggests the RTX 4080's rendering load scales predictably with pixel count, but the absolute headroom at lower settings indicates the CPU can feed the GPU adequately even at 400 FPS.

Medium settings show the most complete dataset with min and max FPS values recorded. At 1080p Medium, the average is 327 FPS with a minimum of 278 and maximum of 376. At 1440p Medium, the average sits at 233 FPS (min 198, max 268), and at 4K Medium it drops to 145 FPS (min 123, max 167). The min-to-max spread narrows slightly as resolution rises, from 98 FPS at 1080p to 70 FPS at 1440p and 44 FPS at 4K, indicating more consistent frame pacing at higher resolutions where GPU-bound scenarios dominate.

High settings present a particularly interesting case. At 1080p High, the combo hits 268 FPS, which drops to 191 FPS at 1440p and 119 FPS at 4K. The 4K High result of 119 FPS is notably close to the 1440p Ultra result of 120 FPS, suggesting that the visual quality difference between High at 4K and Ultra at 1440p costs roughly the same performance. This relationship indicates that resolution scaling and settings scaling interact in a way that lets users trade one against the other.

The data shows that at 1080p across all settings, the system rarely dips below the refresh-rate territory of high-end monitors, with even Ultra maintaining 168 FPS. At 1440p, Ultra drops to 120 FPS while High stays at 191 FPS, and at 4K, only Low and Medium settings clear 144 FPS, with High at 119 FPS and Ultra at 74 FPS. The limiting component shifts from CPU-bound at 1080p Low (where 400 FPS strains even strong processors) to clearly GPU-bound at 4K Ultra, where the RTX 4080's 48.74 TFLOPS FP32 throughput and 716.8 GB/s memory bandwidth are the constraining factors.

Settings Recommendations

The measured rows provide clear guidance for optimizing the Downfall experience with this hardware. For 4K displays, Medium settings deliver the best balance, with an average of 145 FPS and a minimum of 123 FPS that keeps gameplay smooth even in demanding scenes. High settings at 4K still offer 119 FPS average, which is playable, but the jump to Ultra drops the average to 74 FPS — a 37.8% reduction from High that most players would find unnecessary for a horror title where atmosphere matters more than pixel-perfect shadows.

At 1440p, High settings are the sweet spot, producing 191 FPS average. This leaves substantial headroom above 144 Hz displays while maintaining visual fidelity. Ultra at 1440p delivers 120 FPS, which matches exactly the 4K High result, meaning users choosing between 4K High and 1440p Ultra get identical frame rates but different pixel densities. Medium at 1440p hits 233 FPS, which is excessive for most monitors and sacrifices visual quality for performance that cannot be displayed.

For 1080p, the recommendation depends on display refresh rate. Ultra at 168 FPS is the highest quality option that still exceeds 144 Hz, while High at 268 FPS suits 240 Hz and above panels. Low at 400 FPS is purely for competitive scenarios that Downfall, as a horror game, does not require. The data suggests that Medium at 327 FPS offers diminishing returns over High, as the 59 FPS difference between Medium and High is less impactful than the 100 FPS gap between High and Low.

The most efficient experience across all resolutions follows a pattern: choose the highest settings that maintain FPS above your display's refresh rate, and prefer High over Ultra when the delta is large. The 4K Ultra result of 74 FPS, 1440p Ultra of 120 FPS, and 1080p Ultra of 168 FPS show that Ultra settings cost roughly 30-40% performance compared to High, which is a steep price for incremental visual gains in a horror title where dark scenes hide detail anyway.

Low settings yield 285 FPS, Medium averages 233 FPS (min 198, max 268), High produces 191 FPS, and Ultra settles at 120 FPS. The difference between Low and Ultra here is 165 FPS, or 57.9% lower at Ultra. Notably, the 1440p High result of 191 FPS is nearly identical to the 4K High result of 119 FPS being half of 238 — the scaling between 1440p and 4K at High settings is roughly 37.7% faster at 1440p.

At 3840x2160, the RTX 4080's capabilities are tested more thoroughly. Low settings maintain 178 FPS, which is impressive for 4K. Medium drops to 145 FPS (min 123, max 167), High reaches 119 FPS, and Ultra falls to 74 FPS. The 4K Ultra result is the only measured configuration below 100 FPS across all resolutions and settings, highlighting the extreme demands of 4K with maximum quality. The progression from Low to Ultra at 4K shows a 104 FPS drop, a 58.4% reduction.

Comparing identical settings across resolutions reveals consistent scaling patterns. High settings show 268 FPS at 1080p, 191 FPS at 1440p, and 119 FPS at 4K — each step roughly halves the pixel count and produces approximately 30-40% FPS improvement when stepping down. Ultra settings follow the same pattern with 168, 120, and 74 FPS respectively. Low settings show the largest absolute numbers with 400, 285, and 178 FPS, but the relative scaling is similar.

The Medium settings data includes min and max FPS, providing insight into frame consistency. At 1080p, the range spans 278 to 376 FPS; at 1440p, 198 to 268 FPS; and at 4K, 123 to 167 FPS. The average sits near the midpoint of each range, suggesting normal distribution of frame times. The minimum FPS at 4K Medium (123 FPS) exceeds the average FPS at 4K Ultra (74 FPS), demonstrating that Medium settings offer both higher and more consistent performance than Ultra.

How This Combo Ranks

The Intel Core i5-12600KF with NVIDIA GeForce RTX 4080 combination ranks 230 out of 3716 tested combos in Downfall, placing it in the top 6.2% of all configurations. This high percentile reflects the strength of pairing a 79th percentile CPU with an 86th percentile GPU. The rank of 230 means 3486 other combinations perform worse, while 229 outperform this setup.

The CPU's nearest rivals provide context for its contribution to this ranking. The Intel Core i9-10900K scores 27872 on average, which is 0.3% lower than the i5-12600KF's 27799. The AMD Ryzen 7 5800X3D scores 27896, also 0.3% higher. These negligible differences (all within 0.3%) mean the CPU choice is not a differentiator in this game's performance hierarchy — the GPU dominates the ranking position.

The GPU's nearest rivals similarly show tight clustering. The RTX 4080 SUPER scores 54209, just 0.1% above the RTX 4080's 54247. The AMD Radeon Pro W5700X scores 54828 (1.1% higher), while the AMD Radeon RX 6750 GRE 12 GB scores 55698 (2.6% higher) and the AMD Radeon 8060S scores 55757 (2.7% higher). This suggests that the combo's rank is determined more by the GPU tier than by small CPU differences.

Given that 3716 combos were tested, the rank of 230 indicates this pairing is in the upper echelon for Downfall. The game, released in 2016, is not particularly demanding by modern standards, which allows high-end hardware to achieve exceptional frame rates. The combo's percentile ranking reflects that most other tested configurations are lower-tier hardware, pushing this setup into the top percentile despite the game's age.

The data implies that to rank higher, users would need either a more powerful GPU (since the RTX 4080 already sits at the 86th percentile) or a CPU with a higher percentile than the i5-12600KF's 79th. However, the nearest rival deltas of less than 3% on both CPU and GPU suggest that moving up even a few ranks would require significantly more expensive hardware for marginal gains.

CPU Role

The Intel Core i5-12600KF brings 10 cores and 16 threads based on the Alder Lake architecture, with a base clock of 3.70 GHz and boost clock of 4.90 GHz. This 12th-generation processor, built on Intel's 10 nm process, features a 20 MB shared L3 cache and 1.25 MB L2 per core. The 79th percentile ranking among all CPUs places it in the upper-middle tier, but its benchmark scores reveal strong multithreaded performance.

In 3DMark testing, the CPU scores 7956 with 16 threads and 7952 with max threads, showing excellent scaling from 8 threads (6128) to full thread count. Single-thread performance of 1016 in 3DMark and 3302 in Cinebench R23 indicate strong per-core capability, which matters for Downfall's game logic and physics. The PassMark multithread score of 27575 and single-thread score of 3925 reinforce this balanced profile.

The CPU's role in Downfall becomes apparent when examining frame rates at low settings. At 1080p Low, the system produces 400 FPS, which is near the practical ceiling for many game engines regardless of CPU power. The i5-12600KF's 16 threads handle the game's threading model efficiently, as evidenced by the 3DMark scaling from 2 threads (1995) to 4 threads (3806) to 8 threads (6128) — nearly linear scaling that suggests the CPU can feed the GPU without bottlenecking even at extreme frame rates.

However, the CPU's influence diminishes at higher resolutions. The data shows that 1440p Ultra (120 FPS) and 4K High (119 FPS) produce nearly identical results, indicating the GPU becomes the limiting factor. The RTX 4080's 48.74 TFLOPS FP32 throughput and 16 GB of GDDR6X memory with 716.8 GB/s bandwidth are the constraining resources at these settings, not the CPU's 10 cores.

The processor's cache hierarchy — 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3 — provides adequate data locality for a 2016 horror game that does not demand extensive asset streaming. The DDR4 and DDR5 dual-channel memory support, while not benchmarked here, is sufficient for the game's engine. The CPU's 125W TDP and Intel Socket 1700 mounting are relevant for system builders, but the benchmark data shows no thermal throttling issues at the measured frame rates.

Comparing to its nearest rivals, the i5-12600KF's 27799 average benchmark score sits between the i9-10900K (27872, 0.3% higher) and Ryzen 5 8500GE (27712, 0.3% lower). The Ryzen 7 5800X3D (27896, 0.3% higher) and Ryzen 7 6800U (27887, 0.3% higher) round out a tightly clustered group where no CPU holds a meaningful advantage. This parity means Downfall's performance is dictated almost entirely by the GPU, with the CPU providing consistent, bottleneck-free support across all tested configurations.
