Downfall

The Intel Core i5-12600KF paired with the NVIDIA GeForce GTX 1660 Ti delivers playable frame rates in Downfall at most settings, but the data clearly shows a GPU-bound system at higher resolutions. At 1080p, the combo hits 147 FPS on Low, but this drops sharply to 99 FPS on High and 62 FPS on Ultra. The pattern is consistent: the GTX 1660 Ti is the limiting factor as resolution and settings scale upward, while the 10-core i5-12600KF has ample headroom to feed the GPU. The measured results indicate that this pairing is best suited for 1080p Medium or High, with 1440p requiring a settings compromise and 4K only viable on Low.

Resolution Scaling

The FPS drop from 1080p to 4K is significant and reveals a classic GPU-limited scenario. At High settings, the average frame rate falls from 99 FPS at 1920x1080 to 70 FPS at 2560x1440, then to 44 FPS at 3840x2160. This represents a 29 FPS loss moving from 1080p to 1440p, and another 26 FPS loss moving from 1440p to 4K. The scaling is roughly linear, which suggests the GTX 1660 Ti's 6 GB GDDR6 memory and 192-bit bus are being saturated as pixel count increases.

On Low settings, the pattern holds but with higher absolute numbers: 147 FPS at 1080p, 105 FPS at 1440p, and 65 FPS at 4K. The gap between Low and High widens at higher resolutions, indicating that the GPU's shading units and texture units are the bottleneck. At 4K Ultra, the combo manages only 27 FPS, which is unplayable by any standard. The data suggests that at 1080p, the i5-12600KF can push the GTX 1660 Ti to its limits, but at 1440p and above, the GPU's raw throughput — 5.437 TFLOPS FP32 and 169.9 GTexel/s — becomes the dominant constraint.

The Medium preset offers a middle ground, with average FPS of 120 at 1080p, 86 at 1440p, and 53 at 4K. The min FPS data for Medium shows 102 FPS at 1080p and 73 FPS at 1440p, indicating that frame pacing remains consistent even when the average dips. At 4K Medium, the min FPS of 45 is borderline, but the 53 average suggests the game remains playable for slower-paced horror segments. The scaling from 1080p to 1440p is roughly 28% slower, and from 1440p to 4K another 38% slower, which aligns with the pixel count increase of 2.25x and 4x respectively.

GPU Role

The GTX 1660 Ti is built on the Turing architecture with a 12 nm process, featuring 1,536 shading units, 96 texture mapping units, and 48 ROPs. Its base clock runs at 1500 MHz with a boost clock of 1770 MHz, and the 6 GB of GDDR6 memory operates at 12 Gbps effective, delivering 288.0 GB/s of bandwidth. These specifications explain the observed performance: the 192-bit memory bus and 6 GB capacity are adequate for 1080p but strained at 4K, particularly on Ultra settings where the 27 FPS average indicates both memory bandwidth and fill rate limits.

The GPU's pixel rate of 84.96 GPixel/s and texture rate of 169.9 GTexel/s are modest by modern standards, which is why the frame rate drops so precipitously at 4K. The benchmark results show a PassMark G3D score of 12,871, placing the GPU at the 41st percentile of all GPUs. Its nearest rivals, such as the AMD Radeon 540 (0.7% faster) and the AMD Radeon Pro WX 3100 (1.9% faster), are similarly positioned, indicating that this is a mid-range part from the previous generation. The GTX 1660 Ti's DirectX 12 score of 51 in PassMark is notably low, but Downfall is a 2016 release that likely relies on older API paths.

The 120 W TDP and 300 W suggested PSU are modest, and the 1x 8-pin power connector is standard for this class. The GPU's boost clock of 1770 MHz is the key to its 1080p performance, where it can sustain high utilization without thermal throttling. At 4K, the memory bandwidth of 288.0 GB/s becomes the limiting factor, as the data shows a 41% drop from High to Ultra at 3840x2160 (44 FPS to 27 FPS). This suggests that the GPU's ROPs and memory subsystem are overwhelmed by the fill rate demands of Ultra settings at 4K.

CPU Role

The Intel Core i5-12600KF provides a robust foundation for this pairing, with 10 cores and 16 threads based on the Alder Lake architecture. Its base clock of 3.70 GHz and boost clock of 4.90 GHz, combined with a 20 MB shared L3 cache, deliver strong single-threaded and multi-threaded performance. The CPU's Cinebench R23 scores of 23,391 multi-core and 3,302 single-core place it in the 79th percentile of all CPUs, indicating it is far more capable than the GPU requires for Downfall.

The nearest CPU rivals, including the Intel Core i9-10900K (-0.3% delta) and AMD Ryzen 7 5800X3D (-0.3% delta), show that the i5-12600KF is competitive with higher-tier parts from the same era. This means the CPU is not the bottleneck in any of the measured scenarios. At 1080p Low, the 147 FPS average is likely close to the GPU's maximum output, and the CPU's 3DMark single-thread score of 1,016 and 2-thread score of 1,995 suggest it can handle the game's logic and draw calls without issue.

The CPU's 10 nm process and 125 W TDP are efficient, and its support for DDR4 and DDR5 memory gives flexibility, though the dual-channel memory bus is standard. The PassMark multi-thread score of 27,575 and data compression score of 343,231 indicate that the CPU has plenty of headroom for background tasks or streaming while gaming. In Downfall, a horror title that likely does not heavily utilize many threads, the i5-12600KF's single-core performance is what matters, and its boost clock of 4.90 GHz ensures it can keep the GTX 1660 Ti fed even at lower resolutions.

How This Combo Ranks

The combination of the i5-12600KF and GTX 1660 Ti ranks 3,202 out of 3,716 tested combos in Downfall, placing it in the bottom 14% of all configurations. This low ranking is driven entirely by the GPU, as the CPU's percentile (79th) is far higher than the GPU's (41st). The data shows that this combo is outperformed by the vast majority of systems, but the measured frame rates are still playable at 1080p and 1440p on medium settings.

The rank suggests that most other tested combos include more powerful GPUs, which is expected given the GTX 1660 Ti's age and end-of-life production status. However, the combo's performance is consistent with its component positions: the GPU's average benchmark score of 7,723 and the CPU's average of 27,799 indicate a balanced pairing where the GPU is the limiting factor. The 3,716 total combos tested means this is a large database, and a rank of 3,202 confirms that this is a budget-to-midrange configuration from a 2019-era GPU paired with a 2021-era CPU.

For context, the GTX 1660 Ti's nearest rivals in the GPU benchmark — the AMD Radeon 540 (0.7% faster) and Intel Arc A310 (2.3% faster) — show that this GPU is at the lower end of performance. The fact that the combo ranks so low despite the capable CPU underscores that Downfall is GPU-bound in most scenarios. If the goal is to improve the ranking, swapping the GPU for a faster model would yield the biggest gains, but the current combo can still deliver a smooth experience at 1080p Medium.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1920x1080, the Medium preset delivers 120 FPS average with a 102 FPS minimum, which is ideal for smooth gameplay in a horror title where frame drops can break immersion. High settings at 1080p are also viable at 99 FPS, but the 21 FPS drop from Medium is noticeable. Ultra at 1080p is playable at 62 FPS, but the sharp 58 FPS drop from High suggests diminishing returns.

At 2560x1440, Medium is the best choice, with 86 FPS average and 73 FPS minimum, offering a good balance of visual quality and responsiveness. High at 1440p drops to 70 FPS, which is playable but less consistent. Low at 1440p hits 105 FPS, but the visual quality is likely too compromised for a game that relies on atmosphere. Ultra at 1440p is not recommended, as 44 FPS is below the threshold for smooth gameplay.

At 3840x2160, only Low is viable, with 65 FPS average. Medium at 4K drops to 53 FPS with a 45 FPS minimum, which may be tolerable for slower horror sections but risky during action sequences. High at 4K is 44 FPS, and Ultra at 4K is 27 FPS — both are effectively unplayable. The data suggests that this combo should be used at 1080p Medium or High for the best experience, with 1440p Medium as a fallback if a higher-resolution display is used. For 4K, the settings should be set to Low, and even then, the 65 FPS average is the ceiling.
