# Microsoft Flight Simulator — Intel Core i5-11400F + NVIDIA GeForce GTX 1070

The Intel Core i5-11400F paired with the NVIDIA GeForce GTX 1070 delivers playable but constrained performance in Microsoft Flight Simulator, with the data showing a clear pattern: the GTX 1070 becomes the limiting factor as resolution climbs, while the CPU's 6 cores and 12 threads provide adequate headroom for the simulator's demands. The combo ranks 1531 out of 1795 tested combinations, placing it in the lower-middle tier of the database, which aligns with the measured frame rates that range from a smooth 81.7 FPS at 1080p Low to a stutter-prone 27.3 FPS at 4K Ultra.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, revealing that the GTX 1070's 8 GB of GDDR5 memory and 256-bit bus are the primary bottlenecks at higher resolutions. At Low settings, the average frame rate falls from 81.7 FPS at 1920x1080 to 63.6 FPS at 2560x1440, then to 48.3 FPS at 3840x2160 — a total reduction of 33.4 FPS, or roughly 41% from the 1080p baseline. This scaling pattern indicates that the GPU's pixel throughput (107.7 GPixel/s) and texture rate (202.0 GTexel/s) are being saturated as pixel count increases, with the 4K resolution demanding nearly four times the pixel work of 1080p.

At Medium settings, the same resolution progression yields 66.2 FPS at 1080p, 48.6 FPS at 1440p, and 39.1 FPS at 4K — a 27.1 FPS drop from the lowest to highest resolution. The High preset shows an even more pronounced decline: 45.9 FPS at 1080p, 41.3 FPS at 1440p, and 27.3 FPS at 4K, representing a 40.5% performance loss between 1080p and 4K. The Ultra preset mirrors High at 4K (27.3 FPS) but starts lower at 1080p (44.3 FPS), suggesting that the GPU hits a hard ceiling around 27 FPS at 4K regardless of whether High or Ultra settings are selected.

The data points to the GPU as the limiting component at 1440p and 4K. The CPU's 3DMark scores — 5619 in the 16-thread test and 868 in single-thread — are modest but sufficient for this simulator, which is known for heavy single-threaded workloads. The GTX 1070's percentile rank of 51 among all GPUs places it squarely in the midrange, and its average benchmark score of 12331 is nearly identical to the Quadro K4200 (12241, deltaPct 0.7) and GTX 880M (12490, deltaPct -1.3). This midrange positioning explains why the GPU cannot maintain 60 FPS at 1440p or above in this demanding title.

FAQ

Q: What is the best resolution for this combo in Microsoft Flight Simulator?

A: The data shows 1920x1080 as the only resolution where the combo can exceed 60 FPS, achieving 81.7 FPS at Low and 66.2 FPS at Medium. At 2560x1440, the best result is 63.6 FPS at Low, while 3840x2160 never reaches 50 FPS in any tested preset.

Q: How does the GTX 1070 compare to its nearest rivals in this context?

A: The GTX 1070's average benchmark score of 12331 is within 1.7% of its nearest competitors: the Quadro K4200 (12241, deltaPct 0.7), GTX 880M (12490, deltaPct -1.3), GTX 1650 SUPER (12504, deltaPct -1.4), and Tesla K20Xm (12547, deltaPct -1.7). This indicates that the 1070 performs essentially on par with these cards, with no meaningful advantage in raw compute.

Q: Does the CPU bottleneck the GPU at any resolution?

A: At 1080p Low, the 81.7 FPS result suggests the CPU can feed the GPU adequately, but the 6-core, 12-thread i5-11400F with a 4.40 GHz boost clock shows its limits in the 3DMark 2-thread score of 1691. The CPU's 75th percentile ranking among all CPUs is respectable, yet the simulator's single-thread demands may cause occasional frame pacing issues in dense scenes.

Q: What is the difference between High and Ultra settings at 4K?

A: There is no measurable difference: both presets produce exactly 27.3 FPS at 3840x2160. This suggests that the GPU is fully saturated at 4K and additional settings from High to Ultra do not affect the frame rate because the rendering pipeline is already maxed out.

Q: Is the 8 GB VRAM sufficient for this game?

A: The GTX 1070's 8 GB of GDDR5 memory with 256.3 GB/s bandwidth appears adequate for 1080p and 1440p, as frame rates remain playable. At 4K, the 27.3 FPS ceiling at High and Ultra indicates that memory bandwidth (256.3 GB/s) is likely a contributing constraint, though the GPU's overall compute power (6.463 TFLOPS FP32) is the dominant factor.

Q: How does this combo rank among all tested systems?

A: The combo ranks 1531 out of 1795 total combinations in the database, placing it in the bottom 15% of tested systems. This low rank is driven primarily by the GPU's midrange standing (51st percentile) rather than the CPU, which sits at the 75th percentile.

CPU Role

The Intel Core i5-11400F contributes 6 physical cores and 12 threads, running at a base clock of 2.60 GHz and boosting up to 4.40 GHz. In the context of Microsoft Flight Simulator, this processor's single-thread performance is critical, and the benchmark data shows a 3DMark single-thread score of 868, which is modest but not disqualifying. The CPU's multi-threaded capabilities are stronger: 3DMark 16-thread score of 5619, Cinebench R23 multicore of 14372, and PassMark multithread of 16908. These scores indicate that the CPU can handle the simulator's background tasks, such as terrain streaming and AI traffic, without becoming the primary bottleneck in most scenarios.

The CPU's nearest rivals in the database include the AMD Ryzen 7 5700U (avgScore 17189, deltaPct 0), Intel Core i7-1260P (17212, deltaPct -0.2), and Intel Core Ultra 7 164U (17215, deltaPct -0.2). These comparable scores suggest that the i5-11400F's overall processing power is on par with newer mobile and low-power chips, but its desktop-oriented design with 12 MB of shared L3 cache and dual-channel DDR4 support (51.2 GB/s memory bandwidth) is well-suited for sustained gaming loads. The CPU's 65W TDP and 14 nm process node are older technology, yet the data shows no significant thermal throttling impact at the measured frame rates.

In terms of the game's results, the CPU appears to provide sufficient headroom at 1080p Low (81.7 FPS), where the GPU is the limiting factor. At higher resolutions, the CPU's role diminishes further, as the GPU's rendering workload dominates. However, the 3DMark 2-thread score of 1691 is a cautionary data point — Microsoft Flight Simulator's known sensitivity to single-thread performance means the i5-11400F's 4.40 GHz boost clock is the main asset, and the data suggests it is just adequate for maintaining frame rates above 30 FPS at 1440p Medium (48.6 FPS) and 4K Medium (39.1 FPS).

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results: Low settings produce 81.7 FPS, Medium drops to 66.2 FPS, High yields 45.9 FPS, and Ultra is only slightly lower at 44.3 FPS. The spread between Low and Ultra is 37.4 FPS, indicating that the GPU has enough headroom at this resolution to accommodate significant settings changes, though the jump from High to Ultra is negligible (1.6 FPS difference).

At 2560x1440, the frame rates compress: Low achieves 63.6 FPS, Medium 48.6 FPS, High 41.3 FPS, and Ultra 38.0 FPS. The difference between Low and Ultra narrows to 25.6 FPS, showing that the GPU is becoming more strained. Notably, the transition from Medium to High at 1440p costs 7.3 FPS, while High to Ultra costs only 3.3 FPS — a diminishing return pattern that reflects the GPU's limited headroom.

At 3840x2160, the data reveals a hard ceiling. Low settings produce 48.3 FPS, Medium 39.1 FPS, and both High and Ultra plateau at 27.3 FPS. The identical High and Ultra results at 4K are a clear indicator that the GPU is fully saturated, and any additional graphical fidelity from Ultra settings comes without a frame rate penalty because the rendering pipeline cannot go slower. The 21.0 FPS difference between Low and High at 4K, compared to 36.6 FPS at 1080p, quantifies the GPU's diminishing ability to handle settings increases as resolution climbs.

How This Combo Ranks

The combo's rank of 1531 out of 1795 tested combinations places it in the bottom 15% of the database, which is consistent with the GTX 1070's 51st percentile standing among all GPUs and the i5-11400F's 75th percentile among all CPUs. The rank suggests that this pairing is significantly outclassed by most modern systems, particularly those with newer GPUs. The GPU's nearest rivals — the Quadro K4200 (deltaPct 0.7), GTX 880M (deltaPct -1.3), GTX 1650 SUPER (deltaPct -1.4), and Tesla K20Xm (deltaPct -1.7) — all have average scores within 1.7% of the GTX 1070, meaning the GPU is effectively a mid-2010s performance level. The CPU, by contrast, is a more modern part, as evidenced by its nearest rivals including the Intel Core i7-1260P and Core Ultra 7 164U, both with deltaPct values of -0.2.

The discrepancy between the CPU's relatively high percentile (75) and the GPU's middling percentile (51) explains the combo's overall low rank: the system is CPU-heavy relative to its GPU, but Microsoft Flight Simulator is GPU-bound at most resolutions above 1080p. The 1795-combo database includes many systems with far newer GPUs, and the GTX 1070's end-of-life production status and 2016 release date place it at a competitive disadvantage.

Settings Recommendations

For the best balance of frame rate and visual quality, the data points to 1920x1080 Medium as the optimal preset, delivering 66.2 FPS — comfortably above the 60 FPS threshold for smooth gameplay. This setting provides a 20.3 FPS improvement over High at the same resolution while sacrificing only the highest-detail textures and effects. At 1440p, Low settings (63.6 FPS) are the only way to maintain 60+ FPS, but Medium (48.6 FPS) offers a more visually rich experience with a still-playable frame rate. For users prioritizing visual fidelity over smoothness, 1440p High (41.3 FPS) is a viable compromise, though the 4K presets should be avoided entirely — even Low at 4K (48.3 FPS) is marginally playable, but High and Ultra at 27.3 FPS are below the threshold for comfortable flight simulation.

The data shows diminishing returns above Medium: at 1080p, upgrading from Medium to High costs 20.3 FPS (from 66.2 to 45.9), while High to Ultra costs only 1.6 FPS (45.9 to 44.3). This pattern repeats at 1440p (Medium to High: -7.3 FPS; High to Ultra: -3.3 FPS) and 4K (Medium to High: -11.8 FPS; High to Ultra: 0 FPS). A practical recommendation is to start at 1080p Medium and adjust down only if frame rates dip below 60 FPS in dense urban areas or heavy weather — the measured data shows Medium is the highest preset that consistently exceeds 60 FPS at this resolution.

GPU Role

The NVIDIA GeForce GTX 1070, based on the Pascal architecture (GP104 chip, 16 nm process), is the dominant performance factor in this pairing. Its 8 GB of GDDR5 memory on a 256-bit bus delivers 256.3 GB/s of bandwidth, while the GPU operates at base and boost clocks of 1506 MHz and 1683 MHz respectively. With 1920 shading units, 120 TMUs, and 64 ROPs, the GTX 1070 achieves a pixel rate of 107.7 GPixel/s and a texture rate of 202.0 GTexel/s, with FP32 performance of 6.463 TFLOPS. These specifications, combined with its 150W TDP and dual-slot design, define a midrange card that was competitive at launch in 2016 but is now clearly outmatched by modern equivalents.

In Microsoft Flight Simulator, the GPU's role is decisive: the 4K High and Ultra results both plateau at 27.3 FPS, which is a hard floor imposed by the GPU's compute limits. The card's percentile rank of 51 among all GPUs and average benchmark score of 12331 — nearly identical to the GTX 1650 SUPER (12504, deltaPct -1.4) — confirm that this is a midrange performer. The GPU's 3DMark Steel Nomad DX12 score of 1082 and PassMark G3D score of 13498 are modest, but the card's DirectX 12 (12_1) support and Vulkan 1.4 API compatibility ensure it can run the simulator's modern rendering paths, albeit at lower settings. The VRAM capacity of 8 GB is sufficient for 1080p and 1440p, but the 256.3 GB/s bandwidth appears to be a limiting factor at 4K, where the frame rate drops below 50 FPS even at Low settings (48.3 FPS). Overall, the GTX 1070 is the bottleneck in this combo, and the data suggests that upgrading the GPU would yield far greater frame rate improvements than any CPU change for this game.
