Microsoft Flight Simulator

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 4060 delivers a playable experience in Microsoft Flight Simulator, but the data clearly shows that settings management is the key to unlocking its potential. This combination places in the 1020th position out of 1795 tested combos, meaning it sits in the lower-middle portion of the performance spectrum. The measured frames per second across resolutions and presets reveal a system that can handle the simulation, yet it consistently demands trade-offs between visual fidelity and smoothness. For the best overall experience, the Medium preset at 1440p emerges as the standout choice. It produces an average of 72.2 FPS, which comfortably exceeds the 60 FPS threshold for fluid gameplay, while still retaining enough graphical detail to make the world feel immersive. Moving up to High at the same resolution drops the average to 54.6 FPS, which is acceptable but leaves less headroom for the complex scenery and weather systems that can cause frame rate dips.

Settings Recommendations

The measured rows indicate that the Medium preset at 2560x1440 offers the most balanced experience for this hardware combination. It delivers 72.2 FPS on average, which is 17.6 FPS higher than the High preset at the same resolution (54.6 FPS) and 17.9 FPS higher than Ultra (54.3 FPS). The gap between Medium and High is substantial enough that the visual upgrade may not justify the performance cost, especially in a flight simulator where smooth panning over terrain is crucial. For those prioritizing frame rate above all else, the Low preset at 1440p yields a very responsive 93.4 FPS, but this comes at the cost of significantly reduced visual detail. At 1080p, the Medium preset produces 92.9 FPS, which is excellent for high-refresh-rate monitors, but the 1440p Medium option provides a better balance of resolution and fluidity. The Ultra preset is the least advisable choice at any resolution, as it yields 40.8 FPS at 4K, 54.3 FPS at 1440p, and 68 FPS at 1080p, with the 4K figure falling below acceptable playability standards. Stick with Medium for the best combination of visual quality and consistent performance.

GPU Role

The NVIDIA GeForce RTX 4060 is the dominant component in this pairing, and its specifications explain why the frame rates scale so predictably with settings changes. The GPU features 8 GB of GDDR6 memory on a 128-bit bus, providing 272.0 GB/s of bandwidth. This memory configuration is sufficient for 1080p and 1440p gaming, but at 4K resolution, the 8 GB capacity likely becomes a limiting factor, especially on the High and Ultra presets which tax memory capacity more heavily. The GPU's boost clock of 2460 MHz and base clock of 1830 MHz, built on the Ada Lovelace architecture, deliver strong raw compute performance. The measured frame rates show that the GPU handles the transition from Low to Medium settings with relative ease, but the jump from Medium to High and then to Ultra introduces progressively larger performance penalties. At 1080p, the drop from Medium (92.9 FPS) to High (71.8 FPS) is a 21.1 FPS reduction, while the drop from High to Ultra (68 FPS) is only 3.8 FPS. This pattern suggests that the GPU is being pushed to its limits on the higher presets, and the extra visual features in Ultra are not efficiently utilized at this performance tier.

Resolution Scaling

The frame rate scaling across resolutions reveals a system that is primarily GPU-bound at higher settings, but the CPU begins to show its age at lower resolutions. From 1080p to 1440p at High settings, the average FPS drops from 71.8 to 54.6, a decrease of 17.2 FPS. The further drop from 1440p to 4K at High brings the average down to 41.5 FPS, another 13.1 FPS reduction. This linear scaling indicates that the GPU is the limiting component at High settings, as the workload increases with pixel count. However, at Low settings, the scaling tells a different story. The 1080p Low preset achieves 119.4 FPS, while 1440p Low drops to 93.4 FPS and 4K Low reaches 66.5 FPS. The relatively smaller percentage drop from 1080p to 1440p at Low settings (26 FPS) compared to the drop from 1440p to 4K (26.9 FPS) suggests that at lower graphical loads, the Intel Core i5-9400's six cores and six threads are struggling to feed the GPU efficiently. The CPU's boost clock of 4.10 GHz and base clock of 2.90 GHz are adequate for most tasks, but in a simulation-heavy game like Microsoft Flight Simulator, the CPU's single-threaded performance becomes critical, and the 9400's limitations are exposed when the GPU is not the bottleneck.

How This Combo Ranks

The combo rank of 1020 out of 1795 tested combinations places this system in the 56.8th percentile of all tested hardware pairings. This is a middling result, indicating that while this setup is not a top-tier performer, it is also far from the bottom of the pile. The CPU's benchmark scores provide context for this ranking: it achieves 7969 points in Cinebench R23 multi-core and 1125 in single-core, placing it at the 50th percentile of all CPUs. The GPU is comparatively stronger, ranking at the 66th percentile of all GPUs with an average benchmark score of 23181. This disparity suggests that the CPU is holding back the system to some degree, as the GPU has more headroom than the processor can utilize. The nearest rivals to the CPU include the Intel Core i3-10305 (0.2% faster) and the Intel Xeon E-2134 (0.4% faster), while the GPU's closest competitors are the AMD Radeon RX 6600M (0.6% faster) and the NVIDIA GeForce GTX 780 Ti (0.7% faster). The combination's overall rank reflects the balanced but unremarkable nature of this pairing, which is adequate for 1080p and 1440p gaming but not for pushing maximum settings at 4K.

CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor from the Coffee Lake architecture, manufactured on a 14 nm process. With a base clock of 2.90 GHz and a boost clock of 4.10 GHz, it provides solid single-threaded performance for a CPU released in 2018. However, Microsoft Flight Simulator is known for being heavily dependent on single-core performance, and the 9400's 1125-point Cinebench R23 single-core score, while respectable, is not exceptional by modern standards. The CPU's 9 MB of shared L3 cache and dual-channel DDR4 memory support are sufficient for this workload, but the lack of hyper-threading means the processor has only six threads to handle the simulation's various background tasks. In the measured data, the CPU's influence is most apparent at 1080p Low settings, where the GPU has minimal work to do, and the 119.4 FPS result is likely near the CPU's maximum output in this scenario. At 4K Ultra, the CPU's role diminishes as the GPU becomes the primary bottleneck, with the average FPS dropping to 40.8. The CPU's 50th percentile ranking among all processors, compared to the GPU's 66th percentile, reinforces the notion that the processor is the weaker link in this pairing, particularly for a game that values high single-thread performance.

FAQ

Q: What is the best resolution and settings combination for this hardware?

A: The 1440p Medium preset provides the best balance, delivering 72.2 FPS on average. This is significantly smoother than the 54.6 FPS at High and the 54.3 FPS at Ultra, while still offering better visual quality than the Low preset's 93.4 FPS.

Q: Can this system handle 4K gaming in Microsoft Flight Simulator?

A: The data shows that 4K is only playable on the Low preset, which achieves 66.5 FPS. The Medium preset drops to 55.3 FPS, while High and Ultra fall below 42 FPS, making them unsuitable for smooth gameplay.

Q: How does the CPU compare to the GPU in terms of performance?

A: The GPU is the stronger component, ranking at the 66th percentile of all GPUs, while the CPU sits at the 50th percentile. The CPU's Cinebench R23 multi-core score of 7969 and single-core score of 1125 indicate it is a mid-range processor, while the GPU's average benchmark score of 23181 places it in the upper-middle tier.

Q: Is the Ultra preset worth using at 1080p?

A: At 1080p, Ultra delivers 68 FPS, which is only 3.8 FPS lower than High (71.8 FPS). The performance difference is minimal, so if visual fidelity is a priority and you have a 60Hz monitor, Ultra at 1080p is a viable option.

Q: What is the impact of the CPU on performance at lower resolutions?

A: At 1080p Low, the system achieves 119.4 FPS, but this is likely limited by the CPU's six threads and 2.90 GHz base clock. The CPU's single-core score of 1125 in Cinebench R23 suggests it can struggle to keep up with the GPU when graphical loads are light.

Q: How does this combo rank compared to other tested systems?

A: This combination ranks 1020th out of 1795 tested combos, placing it in the lower-middle portion of the performance spectrum. This is consistent with the CPU's 50th percentile and GPU's 66th percentile rankings.
