Downfall

The AMD Ryzen 5 3600 paired with the NVIDIA GeForce GTX 1660 Ti delivers a playable but resolution-sensitive experience in Downfall, a 2016 horror title. The measured frame rates show a clear trajectory: the combination is fully capable at 1080p, becomes demanding at 1440p, and struggles to maintain smooth performance at 4K, particularly at higher quality presets. This analysis breaks down the scaling behavior, the GPU’s role in the results, and how this specific hardware pairing ranks among the 1,741 tested combinations.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals the GTX 1660 Ti as the primary limiting component. At High settings, the average frame rate falls from 102.9 FPS at 1920x1080 to 72.3 FPS at 2560x1440, a reduction of roughly 30%. Moving further to 3840x2160, the average drops to 44.9 FPS, which is a 56% decrease from the 1080p result. This scaling pattern is typical of a GPU-bound scenario where the rendering load on the graphics card increases dramatically with pixel count.

The trend is even more pronounced at Ultra settings. At 1080p, the combo achieves 60.9 FPS, which is acceptable for a horror game. At 1440p, this falls to 43.9 FPS, and at 4K, it plummets to 27.8 FPS. The difference between High and Ultra at 4K is particularly telling: 44.9 FPS versus 27.8 FPS, a gap of 17.1 FPS. This indicates that the Ultra preset’s additional effects impose a heavy cost on the GPU’s limited resources, making 4K Ultra effectively unplayable.

The scaling from Low to Medium provides additional insight. At 1080p, Low yields 149.5 FPS, while Medium delivers 121.2 FPS. At 1440p, the respective figures are 105.6 FPS and 88.8 FPS. The consistent ~20% performance penalty for moving from Low to Medium suggests that the CPU (with its six cores and twelve threads) is not the bottleneck at these lower settings; the GPU’s shading units and memory bandwidth handle the increased load proportionally. However, at 4K, the Low preset still produces 63.9 FPS, which is higher than the High preset’s 44.9 FPS at the same resolution. This demonstrates that lowering settings can recover playability even at 4K, but the margin is slim.

The data shows that the limiting component shifts depending on resolution. At 1080p, the GTX 1660 Ti is the clear constraint, as the Ryzen 5 3600’s single-thread score of 696 in 3dmark and multi-thread score of 4605 suggest ample headroom for this game’s engine. At 4K, the GPU’s 5.437 TFLOPS FP32 throughput and 288.0 GB/s memory bandwidth are simply insufficient to maintain high frame rates, regardless of CPU capability.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture with a 12 nm process, featuring 1,536 shading units and 48 ROPs. Its clock speeds are set at a base of 1500 MHz with a boost of 1770 MHz. The memory configuration consists of 6 GB of GDDR6 on a 192-bit bus, yielding a bandwidth of 288.0 GB/s. These specifications directly influence the measured results in Downfall.

The 6 GB VRAM capacity is adequate for this 2016 title, even at 4K Ultra, but the memory bandwidth becomes a bottleneck at higher resolutions. The 288.0 GB/s figure is modest by modern standards, and the frame rate collapses from 60.9 FPS at 1080p Ultra to 27.8 FPS at 4K Ultra. This 54% drop correlates with the increased memory pressure and pixel fill rate demands at 4K, where the GPU’s pixel rate of 84.96 GPixel/s is stretched thin.

The GPU’s raw compute performance, rated at 5.437 TFLOPS for FP32, is the primary driver of the High preset results. At 1440p High, the combo produces 72.3 FPS, which is playable, but the 4K High result of 44.9 FPS shows the GPU running out of steam. The texture rate of 169.9 GTexel/s is also a factor; at 4K, the increased texture sampling overhead reduces throughput, causing the frame rate to drop below the 60 FPS threshold that many players consider smooth.

The GPU’s percentile ranking of 55 against all GPUs, with an average benchmark score of 13925, places it in the mid-range. Its nearest rivals include the AMD Radeon RX 570X (0.4% faster) and the NVIDIA RTX A2000 Mobile (0.8% slower), indicating that the GTX 1660 Ti sits in a crowded performance tier. In Downfall, this translates to a card that handles 1080p and 1440p comfortably but cannot sustain 4K at higher presets.

To move significantly up the ranking, a user would need a GPU with higher memory bandwidth and more shading units, as the 4K results demonstrate.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo depends on the target resolution. For 1920x1080, the High preset is the best balance, delivering 102.9 FPS. This is well above the 60 FPS threshold, so there is headroom for the Ultra preset at 60.9 FPS, but the visual difference may not justify the 41% performance drop. For players prioritizing smoothness, High is recommended; for those wanting maximum visual fidelity, Ultra remains playable.

At 2560x1440, the Medium preset provides the best experience with 88.8 FPS. The High preset at 72.3 FPS is also acceptable, but the Ultra preset at 43.9 FPS dips below the ideal range for a horror game where responsiveness matters. The Low preset at 105.6 FPS is an option for competitive play, but Medium offers a better balance of visuals and performance.

For 3840x2160, the Low preset is the only viable choice, yielding 63.9 FPS. The Medium preset at 54.3 FPS is borderline, while High (44.9 FPS) and Ultra (27.8 FPS) are not recommended due to stuttering and poor responsiveness. Given the game’s horror genre, a stable frame rate is crucial for immersion, so 4K users should stick to Low settings.

The data indicates that the GTX 1660 Ti is best utilized at 1080p, where it can handle all presets with playable results. At 1440p, Medium is the sweet spot. At 4K, only the lowest settings yield acceptable performance. The recommendation is to prioritize resolution over quality: 1080p High offers the best overall experience, while 4K Low is a compromise for those with 4K displays.
