# Microsoft Flight Simulator: Intel Core i5-10400F + NVIDIA GeForce RTX 3070

The pairing of Intel's six-core Comet Lake CPU with NVIDIA's Ampere-based RTX 3070 produces a balanced 1080p and 1440p experience in Microsoft Flight Simulator, but the data clearly shows that the RTX 3070 is the dominant factor at higher resolutions and quality settings. At 1080p Low, the combo delivers 134.1 FPS, which drops to 76.9 FPS at High and 76.3 FPS at Ultra — a pattern that reveals the GPU's workload scaling. The CPU, with its 6 cores and 12 threads, does not bottleneck the frame rate at lower resolutions, but the GPU's 8 GB GDDR6 memory and 448.0 GB/s bandwidth begin to show limitations as resolution climbs. This is a practical setup for flight sim enthusiasts who prioritize smooth 1440p gameplay over maximum visual fidelity at 4K.

Resolution Scaling

The measured FPS data shows a steep decline as resolution increases, which is typical for a GPU-bound title like Microsoft Flight Simulator. At 1080p Low, the combo achieves 134.1 FPS; moving to 1440p Low drops that to 110.3 FPS (a 17.7% reduction), and at 4K Low it falls further to 77.1 FPS (a 42.5% reduction from 1080p Low). This scaling pattern indicates that the RTX 3070's pixel throughput — rated at 165.6 GPixel/s — is the limiting component, not the i5-10400F's processing power.

At the High preset, the resolution penalty is even more pronounced: 76.9 FPS at 1080p, 64.5 FPS at 1440p, and 45.6 FPS at 4K. The gap between 1080p and 4K at High is 31.3 FPS, or roughly 40.7% lower performance. The Ultra preset follows a similar trajectory, with 76.3 FPS at 1080p, 62.5 FPS at 1440p, and 42.6 FPS at 4K. Notably, the difference between High and Ultra at the same resolution is minimal — only 0.6 FPS at 1080p and 2.0 FPS at 1440p — suggesting that the Ultra preset's additional demands are not significantly taxing the GPU beyond High.

The low preset shows the least resolution sensitivity, which is expected since it reduces the graphical load that stresses the GPU's shading units and texture units. The RTX 3070's 5888 shading units and 184 texture mapping units handle lower-quality settings with headroom, but the 4K Low result of 77.1 FPS still represents a significant drop from 1080p, confirming that resolution scaling is primarily a GPU limitation. The CPU's 12 MB L3 cache and 42.7 GB/s memory bandwidth are sufficient to feed the GPU at all tested resolutions, so the bottleneck shifts entirely to the RTX 3070 as pixel count increases.

How This Combo Ranks

In the benchmark database, this CPU-GPU combination ranks 819th out of 1795 tested combos for Microsoft Flight Simulator, placing it in the 45.6th percentile of all combinations. This mid-pack ranking reflects the balance between the i5-10400F's modest compute capabilities and the RTX 3070's strong rasterization performance. The CPU itself sits at the 73rd percentile against all CPUs in the database, while the GPU ranks at the 72nd percentile against all GPUs — both components are above average individually, yet their combination doesn't crack the top tier due to the CPU's older Comet Lake architecture.

The i5-10400F's nearest rivals in the CPU benchmark database include the AMD EPYC 7552 (0.4% higher average score), the AMD Ryzen 3 7320C (0.8% higher), the Intel Core i5-8500 (1.1% higher), and the AMD Ryzen Embedded V2546 (1.2% higher). These deltas are small, indicating that the i5-10400F's processing power is competitive with a range of server and embedded chips, but it lacks the single-thread headroom that modern flight simulators favor. The Cinebench R23 multicore score of 10297 and single-core score of 1453 show a 7.1x ratio between multi-threaded and single-threaded performance, which is typical for a 6-core/12-thread part.

For the GPU, the RTX 3070's nearest rivals include the AMD FirePro S7150 (0.6% lower average score), the AMD Radeon RX 6600 XT (0.9% higher), the NVIDIA GeForce GTX 980 Ti (1.0% higher), and the AMD Radeon R9 M295X (1.1% lower). These tight margins mean the RTX 3070 sits in a crowded performance band, but its 3DMark Steel Nomad DX12 score of 3162 and Passmark G3D score of 22214 demonstrate solid DirectX 12 capability, which is directly relevant to Microsoft Flight Simulator's rendering pipeline.

FAQ

Q: Is this combo better suited for 1080p or 1440p gaming?

A: The data shows strong 1440p performance, with 64.5 FPS at High and 85.3 FPS at Medium. At 1080p, the same settings yield 76.9 FPS and 103.4 FPS respectively. For a smoother experience, 1080p Medium (103.4 FPS) or 1440p Medium (85.3 FPS) are the sweet spots, while 4K is only playable at Low (77.1 FPS).

Q: How much FPS do you lose going from 1080p to 4K?

A: At Low settings, the drop is from 134.1 FPS to 77.1 FPS, a loss of 57.0 FPS. At High settings, it drops from 76.9 FPS to 45.6 FPS, a loss of 31.3 FPS. The Ultra preset goes from 76.3 FPS to 42.6 FPS, losing 33.7 FPS.

Q: Does the Ultra preset offer better performance than High?

A: No. At 1080p, Ultra (76.3 FPS) is slightly slower than High (76.9 FPS), and the same pattern holds at 1440p (62.5 FPS vs 64.5 FPS) and 4K (42.6 FPS vs 45.6 FPS). The Ultra preset provides no measurable FPS advantage over High in this configuration.

Q: What is the CPU's role in this game's performance?

A: The i5-10400F's 6 cores and 12 threads, with a boost clock of 4.30 GHz, deliver Cinebench R23 multicore scores of 10297 and single-core scores of 1453. These results suggest the CPU can handle the game's simulation logic without bottlenecking the GPU at 1080p and 1440p, as evidenced by the FPS scaling.

Q: Is the RTX 3070's 8 GB VRAM sufficient for this game?

A: The measured results indicate yes for the tested presets. At 4K Ultra, the combo still achieves 42.6 FPS, and at 1440p Ultra it hits 62.5 FPS. The 448.0 GB/s memory bandwidth helps maintain these frame rates, though higher settings may approach the VRAM limit in dense scenery areas.

Q: How does this combo compare to other tested configurations?

A: It ranks 819th out of 1795 combos, which is below the median. The CPU and GPU each rank near the 73rd and 72nd percentiles respectively, but the combination's performance is constrained by the older Comet Lake architecture's memory bandwidth and instruction efficiency.

Settings Recommendations

For the best balance of visual quality and playable frame rates, the Medium preset at 1440p is the standout choice, delivering 85.3 FPS. This is comfortably above the 60 FPS threshold and provides a meaningful resolution upgrade over 1080p while maintaining smooth motion. If you prefer 1080p, the Medium preset at 103.4 FPS offers the highest frame rate with quality settings that still look respectable, and it leaves headroom for dips in complex scenarios.

The High preset is viable at 1440p with 64.5 FPS, but the data shows that Ultra provides almost no additional FPS cost — only 2.0 FPS less at 1440p and 0.6 FPS less at 1080p. Given this negligible difference, there is little reason to choose High over Ultra if your display supports it, since the visual uplift from Ultra is essentially free. However, at 4K, even Low settings (77.1 FPS) are necessary to stay above 60 FPS, and High (45.6 FPS) or Ultra (42.6 FPS) will result in noticeable stutter.

For users with a 144 Hz monitor, 1080p Low (134.1 FPS) is the only setting that fully utilizes the refresh rate, while 1440p Low (110.3 FPS) and 1080p Medium (103.4 FPS) come close. The 4K resolution should be avoided except for screenshots or static viewing, as even Medium (61.8 FPS) barely reaches playable levels, and the 8 GB VRAM may become a limiting factor in densely populated areas.

Measured FPS Breakdown

At 1920x1080, the full settings range shows a clear progression: Low hits 134.1 FPS, Medium drops to 103.4 FPS, High falls to 76.9 FPS, and Ultra is 76.3 FPS. The step from Low to Medium costs 30.7 FPS, while the step from Medium to High costs 26.5 FPS — the largest single jump. High to Ultra is nearly identical, suggesting the Ultra preset's added effects are minimal in this game.

Moving to 2560x1440, the results are: Low at 110.3 FPS, Medium at 85.3 FPS, High at 64.5 FPS, and Ultra at 62.5 FPS. The delta from Low to Medium is 25.0 FPS, from Medium to High is 20.8 FPS, and High to Ultra is only 2.0 FPS. The 1440p results scale down proportionally from 1080p, with the Low preset losing 23.8 FPS and the High preset losing 12.4 FPS.

At 3840x2160, the performance drops sharply: Low achieves 77.1 FPS, Medium 61.8 FPS, High 45.6 FPS, and Ultra 42.6 FPS. The gap between Low and Medium is 15.3 FPS, Medium to High is 16.2 FPS, and High to Ultra is 3.0 FPS. Across all resolutions, the Ultra preset consistently delivers only 2-3 FPS less than High, making High the less efficient choice when both are available.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, manufactured on Intel's 14 nm process. Its base clock of 2.90 GHz boosts to 4.30 GHz, and it features 12 MB of shared L3 cache. In synthetic benchmarks, it scores 10297 in Cinebench R23 multicore and 1453 in single-core, with a Passmark multithread score of 12115 and single-thread score of 2541. These numbers place it at the 73rd percentile of all CPUs, but its nearest rivals — including the AMD EPYC 7552 and Intel Core i5-8500 — are all within 1.2% of its average score, showing that it trades blows with both server and older desktop parts.

In Microsoft Flight Simulator, the CPU's role is to handle the simulation's physics, weather, and AI traffic calculations, which are largely single-threaded. The i5-10400F's single-core performance, as measured by 3DMark single-thread (688) and Geekbench single-core (1454), is adequate for this task, but it lacks the high-frequency advantage of newer architectures. The boost clock of 4.30 GHz helps, yet the 2.90 GHz base clock means sustained loads may cause the CPU to throttle back, potentially affecting frame pacing in dense urban areas.

The CPU's 12 threads provide some headroom for background tasks and game engine threads, but the measured FPS data suggests that the GPU is the primary bottleneck at all resolutions above 1080p Low. The RTX 3070's 17,400 million transistors and 20.31 TFLOPS FP32 throughput are far more demanding of system resources than the CPU's 6 cores can fully utilize, and the 42.7 GB/s memory bandwidth of the i5-10400F is sufficient to feed the GPU's 448.0 GB/s bandwidth without creating a system-level bottleneck. Ultimately, this CPU is a capable partner for the RTX 3070, but it does not boost the combo's ranking beyond the mid-pack.
