Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, one that stresses both the CPU and GPU in ways few other games do. The data for the Intel Core i5-14400F and NVIDIA GeForce RTX 4070 combo reveals a system that is remarkably consistent, but the measured FPS figures show a clear story about where the bottlenecks lie. This analysis digs into the resolution scaling, the combo's overall standing, and what the individual component specifications mean for the flight sim experience.

Resolution Scaling

The measured FPS data shows a steep and predictable drop as resolution increases, which is the classic signature of a GPU-bound workload at higher settings. At 1080p with Low settings, the combo delivers an average of 165 FPS, but at 1440p that figure falls to 133 FPS, and at 4K it drops further to 98 FPS. This is a 40% reduction in average FPS from 1080p to 4K, indicating that the rendering resolution is having a massive impact on the frame rate.

However, the story changes when we look at the Ultra preset. At 1080p Ultra, the average is 92 FPS. Moving to 1440p Ultra, it drops to 74 FPS, and at 4K Ultra, it hits 55 FPS. The percentage drop from 1080p to 4K at Ultra is roughly 40%, which is nearly identical to the Low preset scaling. This suggests that while the resolution is the primary driver of performance loss, the workload scaling is consistent across settings, meaning the game's engine is efficiently distributing the load on the graphics card as resolution increases.

The data implies that at 1080p, the CPU is likely providing enough headroom to keep the GPU well-fed, but the gap between the Low and Ultra presets at the same resolution is telling. At 1080p, there is a 73 FPS gap between Low (165 FPS) and Ultra (92 FPS), which shows that the visual complexity of the Ultra preset is heavily taxing the GPU. The limiting component at 4K is unquestionably the GPU, as the RTX 4070's raw throughput is being saturated, but the consistent scaling suggests that the i5-14400F is not holding the system back at any resolution, keeping the frame pacing stable.

How This Combo Ranks

In the grand scheme of all tested hardware combinations for Microsoft Flight Simulator, this pairing sits in a respectable position. The combo rank is 833 out of 3714 tested combos, placing it in the top 22.4% of all systems. This is a strong showing, indicating that the i5-14400F and RTX 4070 together provide a well-balanced experience for this specific simulator.

The CPU's individual performance metrics support this ranking. The Intel Core i5-14400F has an average benchmark score of 32279, which places it in the 83rd percentile among all CPUs. Its closest rival in the data is the AMD Ryzen 7 PRO 8840U, which has an average score of 32233, a negligible 0.1% difference. This puts the i5-14400F in the same performance tier as high-end mobile and desktop chips from the previous generation, showing it holds its own.

On the GPU side, the RTX 4070 has an average benchmark score of 37648, placing it in the 81st percentile. Its direct rival is the NVIDIA Tesla P4, with a score of 37628, a 0.1% difference. The fact that both the CPU and GPU are in the low-80s percentile explains the system's overall rank—it is not a top-tier enthusiast build, but it is a very capable upper-midrange setup that avoids the severe bottlenecking seen in mismatched pairings.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, and its specifications play a crucial role in Microsoft Flight Simulator's performance. The CPU's base clock is 2.50 GHz, but it can boost up to 4.70 GHz, which is critical for the game's main thread, which handles the simulation logic, physics, and AI traffic. A higher boost clock ensures that this primary thread can process instructions quickly, preventing it from becoming a bottleneck.

The benchmark data for the CPU shows strong single-thread performance, which is vital for this game. In Cinebench R23, the i5-14400F scores 3055 in single-core and 21645 in multi-core. The single-core score is particularly relevant, as many simulation tasks are not perfectly parallelized. The multi-core score of 21645 indicates that the 16 threads are also capable of handling the background tasks like terrain streaming and weather calculations without stealing resources from the main simulation thread.

The CPU's cache hierarchy also contributes to its performance. It has 20 MB of shared L3 cache, which is used to store frequently accessed data for all cores. The L2 cache is a substantial 1.25 MB per core, and the L1 cache is 80 KB per core. This large, fast cache helps reduce memory latency, which is crucial when the game is rapidly loading new scenery and aircraft data. The data suggests that the i5-14400F provides a solid foundation, but the measured FPS at 1080p Low (165 FPS) versus 4K Low (98 FPS) shows that the GPU is still the primary limiting factor in most scenarios.

GPU Role

The NVIDIA GeForce RTX 4070 is the workhorse of this system, and its architecture and memory configuration are directly responsible for the FPS numbers we see. Built on the 5 nm process with the Ada Lovelace architecture, the GPU has a base clock of 1920 MHz and a boost clock of 2475 MHz. This high boost clock is essential for maintaining frame rates in a visually complex environment like a flight simulator, where the camera is constantly moving and rendering dense scenery.

The GPU's memory subsystem is a key strength. It has 12 GB of GDDR6X memory on a 192-bit bus, providing a bandwidth of 504.2 GB/s. This bandwidth is crucial for streaming high-resolution textures and the vast amount of terrain data that Microsoft Flight Simulator loads in real-time. The 504.2 GB/s ensures the GPU cores are not starved of data, which is often a bottleneck in open-world games.

The raw compute power of the RTX 4070 is substantial, with an FP32 performance of 29.15 TFLOPS and 5888 shading units. This allows it to handle the complex shaders and lighting effects present in the Ultra preset. The ray tracing capabilities are supported by 46 RT cores, which are relevant for the game's advanced lighting effects. The data shows that the GPU is the primary scaling factor: at 1080p Low, the average FPS is 165, but at 4K Ultra, it drops to 55. This shows that the GPU's compute and memory bandwidth are being fully utilized as resolution and settings increase.

Settings Recommendations

Based on the measured FPS data, the best experience for a smooth frame rate depends heavily on the target resolution. For 1080p users, the High preset is the sweet spot, delivering an average of 96 FPS. This provides a fluid experience with good visual fidelity, and the jump to Ultra only yields a 4 FPS increase to 92 FPS, which is not worth the potential for more visual noise.

For 1440p, the Medium preset offers the best balance, with an average of 103 FPS. The High preset drops to 78 FPS, which is still playable, but the Medium preset provides a much larger safety margin above the 60 FPS threshold. At 4K, the High preset is the highest setting that maintains a playable average of 57 FPS. The Medium preset at 4K scores 76 FPS, which is a significant improvement over High and is the recommended choice for 4K users who prioritize smoothness over maximum detail.

The Low presets across all resolutions produce high frame rates (165 FPS at 1080p, 133 FPS at 1440p, 98 FPS at 4K), but they sacrifice too much visual quality for a flight simulator, where the environment is the core of the experience. The Ultra preset is only viable at 1080p with a 92 FPS average, but the 1440p (74 FPS) and 4K (55 FPS) results show it is too demanding for those resolutions.

Measured FPS Breakdown

The complete measured FPS data for this combo is as follows:

1920x1080

• Low: average 165 FPS
• Medium: average 128 FPS (min 109, max 147)
• High: average 96 FPS
• Ultra: average 92 FPS

2560x1440

• Low: average 133 FPS
• Medium: average 103 FPS (min 88, max 119)
• High: average 78 FPS
• Ultra: average 74 FPS

3840x2160

• Low: average 98 FPS
• Medium: average 76 FPS (min 65, max 88)
• High: average 57 FPS
• Ultra: average 55 FPS

The data shows a clear pattern: the Medium preset offers the highest FPS with a recorded minimum and maximum, indicating strong frame pacing. The High and Ultra presets are close in performance at each resolution, suggesting that the Ultra preset's additional effects have a diminishing return on FPS. The Low preset is the outlier, providing a massive boost in frame rate at the cost of visual fidelity. This breakdown confirms that the RTX 4070 has enough headroom to run the game well at 1080p and 1440p, but 4K requires careful settings management to stay above 60 FPS.
