Settings Recommendations

The measured data across all three resolutions shows a consistent hierarchy: Low delivers the highest average FPS, followed by Medium, then High, with Ultra always the slowest. At 1920x1080, Low averages 216 FPS, Medium 176 FPS, High 145 FPS, and Ultra 90 FPS. For a horror game where smooth motion and responsiveness matter, the Medium preset provides an excellent balance — it keeps the average above 170 FPS at 1080p while offering noticeably better visual fidelity than Low. The Medium preset also shows a minimum of 150 FPS at 1080p, which is still well above display refresh rates for most monitors.

At 2560x1440, Medium averages 126 FPS with a minimum of 107 FPS and maximum of 145 FPS. That is comfortably playable on high-refresh 1440p displays. High at 1440p drops to 103 FPS average, which remains smooth but leaves less headroom for demanding scenes. Ultra at 1440p falls to 65 FPS average, which is playable but begins to approach the threshold where frame pacing issues become noticeable in a horror title. At 3840x2160, Medium averages 78 FPS with a minimum of 67 FPS, making it the recommended preset for 4K — it stays above 60 FPS while High drops to 64 FPS average and Ultra falls to 40 FPS.

The best experience across the board is Medium. It consistently maintains playable frame rates at every resolution, with the 1080p minimum of 150 FPS ensuring no stutter-heavy sections. High is acceptable at 1080p and 1440p, but at 4K it is borderline. Ultra is only viable at 1080p, where 90 FPS average still holds up, but the 40 FPS result at 4K makes it unsuitable for that resolution. Low is the pick for competitive or maximum-refresh scenarios, especially at 1080p where 216 FPS average pushes past most high-refresh monitors' limits.

Resolution Scaling

The FPS drop from 1080p to 4K reveals how the GTX 1080 Ti increasingly becomes the limiting factor as pixel count rises. At Low settings, the average falls from 216 FPS at 1920x1080 to 154 FPS at 2560x1440 (a 28.7% drop), then to 96 FPS at 3840x2160 (a 37.7% drop from 1440p). At High settings, the progression is 145 to 103 to 64 FPS, with the 1440p-to-4K drop of 37.9% being steeper than the 1080p-to-1440p drop of 29.0%. Medium settings show 176 to 126 to 78 FPS, where the 4K result is 38.1% below the 1440p result. Ultra exhibits the largest relative decline: 90 to 65 to 40 FPS, with the 4K figure representing only 44.4% of the 1080p average.

The scaling pattern indicates that at 1080p, the CPU still has meaningful influence — the i5-13400F's strong single-thread performance (3191 in Cinebench R23 single-core, 3634 in PassMark single-thread) helps push frame rates above 200 FPS at Low settings. As resolution climbs, the GPU's raw throughput — 11.34 TFLOPS FP32, 354.4 GTexel/s texture rate, and 139.2 GPixel/s pixel rate — becomes the bottleneck. The 4K Ultra result of 40 FPS is particularly telling: the 11 GB memory and 484.4 GB/s bandwidth are sufficient for capacity, but the Pascal architecture's compute and fill-rate limits cap performance. The delta between Low and Ultra at each resolution also widens with resolution, confirming that the GPU is the primary scaling constraint.

The fact that Medium at 4K (78 FPS) outperforms Ultra at 4K (40 FPS) by nearly double suggests that the Ultra preset introduces effects that heavily tax the GP102 chip. Since the CPU maintains high scores in threaded workloads (22604 in Cinebench R23 multi-core, 7314 in 3DMark 16-thread), it is not the limiting factor at higher resolutions. Users with 4K displays should target Medium for a stable 60+ FPS experience, while 1080p users can safely push to High or Ultra.

Measured FPS Breakdown

At 1920x1080, the full settings spectrum shows the GTX 1080 Ti's headroom at lower resolutions. Low settings deliver an average of 216 FPS, with no minimum or maximum recorded. Medium averages 176 FPS, with a minimum of 150 FPS and maximum of 203 FPS. High averages 145 FPS, and Ultra averages 90 FPS. The gap between Low and Ultra is 126 FPS, meaning Ultra delivers only 41.7% of Low's frame rate. Even at Ultra, 90 FPS average is smooth for most displays, making 1080p the most forgiving resolution for this combo.

At 2560x1440, the pattern compresses. Low averages 154 FPS, Medium 126 FPS (minimum 107, maximum 145), High 103 FPS, and Ultra 65 FPS. The spread between Low and Ultra narrows to 89 FPS, with Ultra now at 42.2% of Low's performance. Medium remains the sweet spot, holding a minimum of 107 FPS that clears the 60 FPS mark with substantial margin. High at 103 FPS average is also viable for 1440p high-refresh monitors, though the lack of a recorded minimum means worst-case dips could be lower.

At 3840x2160, the GPU's limits become apparent. Low averages 96 FPS, Medium 78 FPS (minimum 67, maximum 90), High 64 FPS, and Ultra 40 FPS. The Low-to-Ultra gap shrinks to 56 FPS, with Ultra now at 41.7% of Low. Medium's minimum of 67 FPS is the only preset that guarantees above-60 FPS at 4K. High dips to 64 FPS average, which means some scenes will drop below 60. Ultra at 40 FPS is borderline for a horror game where smooth motion is critical for atmosphere. The Medium preset's recorded range of 67-90 FPS shows consistency, whereas the other presets lack min/max data, suggesting Medium was the only setting tested with frame-time capture.

Comparing across resolutions, 1080p Medium (176 FPS) outperforms 1440p High (103 FPS) by 70.9%, and 1440p Medium (126 FPS) outperforms 4K High (64 FPS) by 96.9%. The 4K Ultra result of 40 FPS is the only measured value below 60 FPS across all tested configurations.

GPU Role

The NVIDIA GeForce GTX 1080 Ti, built on the Pascal architecture with the GP102 chip at 16 nm, carries 11 GB of GDDR5X memory on a 352-bit bus. Memory clocks run at 1376 MHz with 11 Gbps effective speed, producing 484.4 GB/s of bandwidth. The GPU's base clock is 1481 MHz with a boost of 1582 MHz. Its compute resources include 3584 shading units, 224 texture mapping units, and 88 raster operations pipelines, yielding 11.34 TFLOPS FP32, 354.4 GTexel/s texture fill, and 139.2 GPixel/s pixel fill.

These specifications map directly to the measured FPS results. At 4K Ultra, the 40 FPS average suggests the GPU is saturated on both pixel fill and shader work — the 88 ROPs must handle 3840x2160 resolution (8.3 million pixels) while the 3584 shading units process the Ultra preset's lighting and post-processing effects. The 11 GB VRAM capacity is not the constraint; even at 4K Ultra, the memory size is ample for the game's textures. Instead, the bandwidth of 484.4 GB/s and the FP32 throughput of 11.34 TFLOPS cap performance.

The GPU's percentile rank of 58 places it below the top half of all GPUs, and its average benchmark score of 15548 is within 1.7% of the RTX 2060 and GTX 580. In this game, the GTX 1080 Ti's Pascal architecture lacks hardware ray tracing or tensor cores, but Downfall is a 2016 horror title that does not require those features. The GPU's DirectX 12 support (12_1) and Vulkan 1.4 API compatibility are sufficient. The 250 W TDP and dual-slot design with 1x 6-pin + 1x 8-pin power connectors indicate a high-power card, and the suggested 600 W PSU reflects that draw.

The benchmark results show the GPU holding up well at 1080p and 1440p, where its high fill rates and memory bandwidth keep frame rates above 100 FPS on most presets. At 4K, the 64 FPS average at High and 40 FPS at Ultra reveal the architectural limits — the Pascal chip's FP32 rate and ROP count are not enough for heavy 4K workloads. The GTX 1080 Ti's process node of 16 nm and die size of 471 mm² with 11,800 million transistors explain its thermal and power profile, but the data shows it remains a capable 1080p and 1440p card for this game.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread desktop processor based on Raptor Lake architecture, manufactured on Intel's 10 nm process. It runs at a 2.50 GHz base clock with a 4.60 GHz boost clock, has a 65 W TDP, and fits the Intel Socket 1700. Cache hierarchy includes 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. The CPU supports both DDR4 and DDR5 memory via a dual-channel memory bus, with PCIe Gen 5 providing 16 lanes from the CPU.

The CPU's benchmark profile shows strong multi-threaded performance: Cinebench R23 multi-core scores 22604, Cinebench R20 multi-core 8892, Cinebench R15 multi-core 2278, Geekbench multi-core 11068, and PassMark multi-thread 25032. Single-thread results are also solid: Cinebench R23 single-core 3191, Cinebench R20 single-core 1255, Geekbench single-core 1996, and PassMark single-thread 3634. The 3DMark tests reveal scaling from 1880 (2 threads) to 3459 (4 threads) to 5591 (8 threads) to 7314 (16 threads) to 7307 (max threads), showing near-linear scaling up to 8 threads then a plateau.

For Downfall, a horror game from 2016, the CPU's role is most evident at lower resolutions. At 1080p Low, the 216 FPS average requires the CPU to feed the GPU with enough draw calls and game logic updates per frame. The i5-13400F's single-thread score of 3191 in Cinebench R23 suggests it can handle high frame-rate scenarios without bottlenecking. The 10-core, 16-thread configuration also provides headroom for background tasks and streaming overhead, though the game itself likely uses fewer threads.

The CPU's percentile rank of 77 and average benchmark score of 25292 place it near the AMD Ryzen 9 6900HS (25284, 0% delta) and AMD Ryzen 7 6800H (25201, 0.4% behind). The 4.60 GHz boost clock is critical for single-thread-bound sections of the game, while the 20 MB L3 cache helps with data locality. The 65 W TDP means thermals are manageable, allowing sustained boost clocks during extended play sessions.

At 4K, the CPU's influence diminishes. The FPS drops from 216 (1080p Low) to 96 (4K Low) are driven primarily by GPU load, not CPU limits. The data indicates the i5-13400F is never the bottleneck in this game — even at 1080p Ultra (90 FPS) and 1080p Low (216 FPS), the CPU's thread scheduling and clock speeds are sufficient. The absence of a measured minimum FPS for most presets suggests stable performance without CPU-caused stutters. The CPU's memory support for DDR4 and DDR5 means the platform can pair with either memory type, and the dual-channel bus provides adequate bandwidth for the game's data streaming needs.
