Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the Intel Core i5-14400F and NVIDIA GeForce RTX 3070 Ti reveals a clear pattern: performance scales predictably with resolution, but the scaling factor is heavily influenced by the graphics preset. From 1080p to 4K at Low settings, the average frame rate drops from 139.7 FPS to 86.1 FPS, a reduction of approximately 38%. At Ultra settings, the same resolution jump sees the average frame rate fall from 76.7 FPS to 43.5 FPS, a steeper drop of roughly 43%. This indicates that at higher presets, the GPU becomes the limiting component more aggressively as pixel count increases.

The data shows that the gap between 1440p and 4K is more pronounced than the gap between 1080p and 1440p, particularly at higher settings. At High settings, moving from 1080p (81 FPS) to 1440p (65.9 FPS) costs about 19% performance, while moving from 1440p to 4K (50.3 FPS) costs another 24%. This non-linear scaling is typical of a GPU-bound scenario at higher resolutions. Conversely, at Low settings, the drop from 1080p (139.7 FPS) to 1440p (113.8 FPS) is about 19%, and from 1440p to 4K (86.1 FPS) is about 24%, showing a similar proportional trend but with higher absolute headroom.

The interpretation is straightforward: at 1080p, the CPU has more influence on the result, as the RTX 3070 Ti can push very high frame rates. At 4K, the GPU's workload increases dramatically, and the frame rates settle into a range that suggests the graphics card is the primary bottleneck. The fact that Ultra settings at 4K produce 43.5 FPS while Low settings at the same resolution produce 86.1 FPS underscores how much headroom exists in the graphics pipeline when settings are reduced. This is a GPU-limited scenario at 4K, while at 1080p, the combination is more balanced, with the CPU able to feed the GPU adequately.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor from the Raptor Lake Refresh generation, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Its benchmark scores indicate strong multi-threaded capability, with a Cinebench R23 multi-core score of 21,914 and a Passmark multi-thread score of 25,783. The single-thread performance is also respectable, with a Cinebench R23 single-core score of 3,093 and a Passmark single-thread score of 3,723. These figures place the CPU in the 88th percentile among all tested CPUs, meaning it outperforms the vast majority of processors in general compute tasks.

In Microsoft Flight Simulator, the CPU's role is significant because the simulation engine handles vast amounts of world data, physics, and AI traffic. The data shows that at 1080p Low settings, the combination achieves 139.7 FPS, which is the highest measured result in the entire dataset. This suggests that the CPU can drive the simulation engine fast enough to avoid bottlenecking the GPU at lower graphical loads. However, the CPU's nearest rivals, such as the Intel Core i7-12800H and AMD Ryzen 5 PRO 7645, have average scores within 0.2% of the i5-14400F, indicating that this processor is positioned in a competitive mid-range segment.

The boost clock of 4.70 GHz is crucial for the single-threaded portions of the flight simulator, which often rely on one main thread for core simulation logic. The measured frame rates at 1080p across all settings (from 76.7 FPS at Ultra to 139.7 FPS at Low) show that the CPU is capable of maintaining playable performance even when the GPU is not the limiting factor. The 10-core configuration with 16 threads also helps with background tasks like terrain streaming and weather updates, which can be parallelized. Overall, the data indicates that the i5-14400F is not the primary constraint in this pairing, especially at higher resolutions where the GPU workload dominates.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is an Ampere-architecture GPU with 8 GB of GDDR6X memory on a 256-bit bus, delivering a memory bandwidth of 608.3 GB/s. Its boost clock is rated at 1770 MHz, and it features 6,144 shading units. The GPU's benchmark scores include a Passmark G3D score of 23,356 and a 3DMark Steel Nomad DX12 score of 3,478, placing it in the 74th percentile among all GPUs. Its nearest rivals, such as the AMD Radeon RX 6700 and NVIDIA Quadro M5000, have average scores within 1.2% of the RTX 3070 Ti, showing that it sits in a well-contested performance tier.

In Microsoft Flight Simulator, the GPU's role is most evident at 4K resolution, where the average frame rates range from 43.5 FPS at Ultra to 86.1 FPS at Low. The steep drop from Ultra to Low at 4K (43.5 to 86.1 FPS) demonstrates how sensitive the game is to GPU workload, particularly with the high-detail terrain and aircraft models. The 8 GB VRAM capacity is a notable factor; at 4K Ultra, the game is likely pushing against this limit, which may explain why the frame rate falls to 43.5 FPS, the lowest measured value in the dataset. At 1080p, the GPU has more headroom, with Ultra settings still delivering 76.7 FPS, indicating that the VRAM and compute resources are sufficient for lower pixel counts.

The memory bandwidth of 608.3 GB/s is a key strength for this GPU in a flight simulator, as the game streams large textures and geometry data continuously. The data shows that the GPU is the limiting component at 4K across all settings, as frame rates are significantly lower than at 1080p, even when the CPU is capable of higher output. The RTX 3070 Ti's performance in this game is solid but not spectacular at 4K, with the Ultra preset falling below the 60 FPS threshold, which is a common target for smooth flight simulation.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across resolutions and settings. At 1080p, the combination starts at 76.7 FPS on Ultra, rises to 81 FPS on High, jumps to 112.6 FPS on Medium, and peaks at 139.7 FPS on Low. This shows a clear progression where reducing settings from Ultra to Low yields a 45% increase in frame rate, indicating that the GPU is the primary limiter at this resolution. The gap between Ultra and High is small (76.7 to 81 FPS), suggesting that the Ultra preset adds a heavy graphical burden without a proportional performance cost reduction when moving to High.

At 1440p, the frame rates are 65.3 FPS on Ultra, 65.9 FPS on High, 91.6 FPS on Medium, and 113.8 FPS on Low. The Ultra and High presets are nearly identical in performance, differing by less than 1 FPS, which indicates that the visual difference between these two presets at this resolution is minimal in terms of GPU load. The Medium preset provides a substantial boost to 91.6 FPS, making it a viable option for smoother gameplay. At 4K, the frame rates drop to 43.5 FPS on Ultra, 50.3 FPS on High, 66.3 FPS on Medium, and 86.1 FPS on Low. The jump from High to Medium at 4K (50.3 to 66.3 FPS) is a 32% improvement, which is significant for playability.

Comparing resolutions, the data shows that at Low settings, even 4K delivers 86.1 FPS, which is above the 60 FPS threshold. At Medium settings, 4K drops to 66.3 FPS, still playable, but at High and Ultra, 4K falls below 60 FPS. This suggests that for 4K gaming, the user must accept Medium settings or lower to maintain smooth performance. At 1440p, all settings except Ultra are above 60 FPS, with Ultra at 65.3 FPS barely clearing the threshold. At 1080p, all settings are above 76 FPS, making it the most flexible resolution for this combination.

For 1080p gaming, the Ultra preset delivers 76.7 FPS, which is above the 60 FPS threshold and provides the best visual quality. The High preset at 81 FPS offers a slight performance boost with a marginal visual reduction, but the data shows the difference is small. For players prioritizing frame rate, the Medium preset at 112.6 FPS provides a substantial jump, but the Low preset at 139.7 FPS is likely excessive for most monitors, which typically cap at 144 Hz.

At 1440p, the Ultra preset at 65.3 FPS is just above 60 FPS, making it a viable option for users who prefer maximum visual fidelity. The High preset at 65.9 FPS is nearly identical in performance, so the choice between the two comes down to personal preference. For a smoother experience, the Medium preset at 91.6 FPS is the best balance, offering a significant frame rate increase while maintaining decent visual quality. The Low preset at 113.8 FPS is available for users with high-refresh-rate 1440p monitors, but the visual compromise is substantial.

At 4K, the situation is more constrained. The Ultra preset at 43.5 FPS is below the 60 FPS threshold and may not be suitable for smooth gameplay. The High preset at 50.3 FPS is an improvement but still falls short. The Medium preset at 66.3 FPS is the recommended choice for 4K, as it clears the 60 FPS mark and delivers a playable experience. The Low preset at 86.1 FPS is the best option for users who prioritize frame rate over visuals, but the reduction in detail is noticeable. Overall, the data suggests that Medium settings at 4K, High settings at 1440p, and Ultra settings at 1080p are the sweet spots for this combination.
