Microsoft Flight Simulator

The Intel Core i7-14700KF with the NVIDIA GeForce RTX 4080 is a high-end pairing built to handle demanding simulations, and the measured data for Microsoft Flight Simulator confirms that this combo delivers strong frame rates across all tested settings and resolutions. This analysis breaks down how each component contributes to the results, how the system scales across resolutions, and which settings provide the most balanced experience.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-14700KF is a 20-core, 28-thread processor from the Raptor Lake Refresh generation, built on Intel’s 10 nm process. Its base clock is 3.40 GHz, boosting up to 5.60 GHz, which is crucial for a flight simulator that relies heavily on single-thread performance for physics, flight model calculations, and scenery loading. The CPU’s L3 cache is 33 MB shared, with 2 MB L2 per core and 80 KB L1 per core, providing fast access to frequently used data. In synthetic benchmarks, this CPU scores 6,235 in Cinebench R23 single-core and 44,167 in multi-core, placing it in the 94th percentile of all CPUs. The nearest rivals include the AMD Ryzen 7 9700F with an average score of 69,996 (0.2% ahead), the AMD Ryzen 9 7940HX at 69,875 (0.4% ahead), the AMD Ryzen 9 7950X at 69,515 (0.9% ahead), and the Intel Core Ultra 7 265K at 70,879 (1% behind). This shows the i7-14700KF is competitive with top-tier alternatives, though a slight edge goes to the 265K in aggregate benchmark scores.

For Microsoft Flight Simulator specifically, the CPU’s high boost clock is the defining trait. The game’s engine is known for being CPU-bound in scenarios like dense urban areas or complex weather systems, where per-core performance dictates frame pacing. The 5.60 GHz boost ensures that the main simulation thread gets maximum throughput, which is reflected in the measured FPS data. At 1080p Low settings, the combo achieves 211 FPS, which is far beyond typical display refresh rates, indicating that the CPU is not a bottleneck at lower resolutions. Even at 4K Ultra, where the GPU is heavily loaded, the CPU still manages to feed the graphics card enough data to maintain 70 FPS, which is respectable for a simulation of this complexity. The 20 cores also help with background tasks like scenery streaming, AI traffic, and multiplayer syncing, though the game’s primary thread remains the limiting factor in many scenes. The Cinebench R15 multi-core score of 4,452 and single-core of 628 further underscore the processor’s balance, but for this game, the single-core result is more telling. The PassMark single-thread score of 4,480 aligns with the boost clock behavior, and the data suggests that users upgrading from older platforms will see meaningful gains in flight sim performance, especially at 1080p where the CPU has more headroom.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture using TSMC’s 5 nm process, with a chip size of 379 mm² and 45,900 million transistors. It features 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of bandwidth, which is essential for handling high-resolution textures in Microsoft Flight Simulator. The GPU’s base clock is 2205 MHz, boosting to 2505 MHz, with memory running at 1400 MHz (22.4 Gbps effective). The RTX 4080 has 9,728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores, providing 48.74 TFLOPS of FP32 performance. In benchmark results, it scores 34,457 in PassMark G3D and 20,671 in GPU compute, placing it in the 86th percentile of all GPUs. Its nearest rivals include the RTX 4080 SUPER (0.1% ahead in average score), the AMD Radeon Pro W5700X (1.1% behind), the AMD Radeon RX 6750 GRE 12 GB (2.6% behind), and the AMD Radeon 8060S (2.7% behind). The RTX 4080 is essentially on par with the 4080 SUPER, with the difference being negligible in real-world gaming.

In the context of Microsoft Flight Simulator, the GPU’s VRAM capacity is a key asset. The game streams vast amounts of terrain and photogrammetry data, and 16 GB allows the card to hold more assets without stutter. The measured FPS data shows that the GPU is the primary driver of performance at higher resolutions. At 4K Ultra, the average FPS is 70, which drops to 73 at High, showing that Ultra settings are more demanding but still playable. The 716.8 GB/s bandwidth ensures that texture streaming keeps pace with the CPU’s requests, which is critical when flying over detailed landscapes. The boost clock of 2505 MHz is typical for a high-end card, and the data shows that the RTX 4080 scales well with resolution, as evidenced by the 4K Medium result of 97 FPS compared to 125 FPS at Low. The GPU’s 84th percentile ranking means it outperforms most cards on the market, and for this flight sim, it provides a solid foundation for both 1440p and 4K gaming. The RTX 4080’s 16 GB VRAM also future-proofs against upcoming add-ons and world updates that might increase texture sizes, though the measured data already shows strong performance at the highest tested settings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of performance scaling across resolutions, which indicates how the workload shifts between CPU and GPU. At 1080p Low, the combo achieves 211 FPS, while at 1440p Low it drops to 170 FPS, and at 4K Low it falls to 125 FPS. This represents a 40.8% drop from 1080p to 1440p and a 26.5% drop from 1440p to 4K, showing that the GPU becomes increasingly important as pixel count rises. For Medium settings, the FPS goes from 164 at 1080p to 132 at 1440p and 97 at 4K, with drops of 19.5% and 26.5% respectively. High settings show a similar trend: 123 FPS at 1080p, 99 FPS at 1440p, and 73 FPS at 4K, representing a 19.5% drop and then a 26.3% drop. Ultra settings are the most demanding, with 117 FPS at 1080p, 95 FPS at 1440p, and 70 FPS at 4K, showing drops of 18.8% and 26.3%.

The pattern of diminishing returns as resolution increases is typical of a system where the GPU is the bottleneck at higher pixel counts. At 1080p, the CPU’s high boost clock allows the RTX 4080 to run at near-peak efficiency, but as resolution climbs, the GPU’s fill rate and memory bandwidth become the limiting factors. The fact that Ultra settings only cause a small FPS drop from High (e.g., 73 to 70 FPS at 4K) suggests that the game’s Ultra preset adds extra visual effects that are not overly taxing on the GPU, at least compared to the resolution jump. Conversely, Low settings show the largest absolute FPS values, indicating that the CPU can sustain high frame rates when the GPU is under less load. The data also shows that the gap between Low and Ultra narrows as resolution increases: at 1080p, the difference is 94 FPS (211 vs 117), while at 4K, it’s 55 FPS (125 vs 70). This is a strong indicator that the GPU is the primary constraint at 4K, whereas at 1080p, the CPU’s performance ceiling is more apparent. For users with high-refresh monitors, 1080p or 1440p Medium or High settings will yield the best balance, while 4K users should stick to High or Ultra for visual fidelity, accepting the lower frame rates.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the ideal settings depend on the user’s target resolution and refresh rate. For 1080p, the Medium preset at 164 FPS is the sweet spot, offering a 33.5% improvement over High (123 FPS) while still maintaining good visual quality. Low settings at 211 FPS are excessive for most displays, unless the user has a 240 Hz monitor and prioritizes competitive smoothness over visuals. Ultra at 117 FPS is also playable, but the 47 FPS gap between Ultra and Medium suggests that the visual gains from Ultra are minor compared to the performance cost. For 1440p, Medium at 132 FPS is again the best choice, providing a 33 FPS advantage over High (99 FPS) and a 37 FPS advantage over Ultra (95 FPS). Low at 170 FPS is unnecessary for typical 1440p monitors (144 Hz or similar), but it’s there for those who want the absolute highest frame rates. High and Ultra are nearly identical in performance (99 vs 95 FPS), so High is recommended for a slight FPS boost with negligible visual differences.

At 4K, the situation shifts. Medium at 97 FPS is the highest playable preset, but High at 73 FPS and Ultra at 70 FPS are both acceptable for a flight simulator, which is not a competitive shooter and doesn’t require extreme frame rates. Low at 125 FPS is overkill for 4K displays, which typically cap at 60-120 Hz. The data shows a 27 FPS difference between Medium and High (97 vs 73), which suggests that High adds significant visual fidelity (like better shadows and reflections) at a substantial cost. Ultra at 70 FPS is only 3 FPS behind High, so users who want the best image quality should choose Ultra if they can tolerate the slight drop. However, for a smooth experience, Medium at 4K is the recommended preset, as it maintains frame rates above 90 FPS, which is rare for this game at that resolution. The min FPS data for Medium at 4K is 83 FPS, which is still comfortable, while the max of 112 FPS shows headroom. Overall, the measured rows indicate that Medium is the most balanced preset across all resolutions, with High being a good alternative for 1080p and 1440p users who prioritize visuals over frame rate.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations, this pairing of the Intel Core i7-14700KF and NVIDIA GeForce RTX 4080 ranks 215th out of 3,714 combos for Microsoft Flight Simulator, placing it in the top 5.8% of all systems tested. This percentile is notable because flight simulators are notoriously demanding, and the fact that this combo sits in the 94th percentile for CPU and 86th percentile for GPU suggests that the overall system is well-balanced. The rank of 215 means there are 214 combos that perform better, likely including configurations with higher-end GPUs like the RTX 4090 or CPUs with higher single-core scores, but the margin is small for most practical purposes. The combo’s rank is a reflection of the measured FPS across all settings and resolutions, and the data shows that it handles 4K Ultra at 70 FPS, which is a strong result for a game that often struggles to maintain 60 FPS on lesser hardware.

Compared to other combos, the i7-14700KF’s nearest CPU rivals (like the Ryzen 7 9700F and Ryzen 9 7950X) would likely produce similar FPS in this game, given their comparable benchmark scores. The GPU’s nearest rival, the RTX 4080 SUPER, is nearly identical in performance, so any combo with that card would rank similarly. However, the rank of 215 out of 3,714 indicates that this is a high-end setup that outperforms the vast majority of tested systems. For context, the fact that the combo achieves over 100 FPS at 1080p Low and over 90 FPS at 4K Medium puts it ahead of many mainstream configurations. The data suggests that users with this combo can expect a consistently smooth experience in Microsoft Flight Simulator, even at 4K, which confirms both the CPU’s single-core power and the GPU’s memory bandwidth. The rank also implies that there is some headroom for improvement, perhaps by overclocking the CPU (which is multiplier-unlocked) or the GPU, but the stock performance is already competitive.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1080p, the combo delivers 211 FPS on Low, 164 FPS on Medium, 123 FPS on High, and 117 FPS on Ultra. The Medium preset has a min of 139 FPS and max of 188 FPS, indicating stable frame pacing. At 1440p, the numbers are 170 FPS on Low, 132 FPS on Medium (min 112, max 152), 99 FPS on High, and 95 FPS on Ultra. At 4K, the performance drops to 125 FPS on Low, 97 FPS on Medium (min 83, max 112), 73 FPS on High, and 70 FPS on Ultra. These figures show a consistent scaling pattern: Low settings always provide a significant FPS boost, while Ultra is only slightly slower than High, suggesting that the Ultra preset includes some effects that are not fully GPU-bound.

The min and max FPS values for Medium settings across all resolutions are particularly useful for understanding frame time consistency. At 1080p Medium, the range is 139-188 FPS, which is a 49 FPS spread, indicating some variance but still well above refresh rates. At 1440p Medium, the range is 112-152 FPS (40 FPS spread), and at 4K Medium, it’s 83-112 FPS (29 FPS spread), showing that the frame rate becomes more stable as resolution increases, likely because the GPU is more consistently loaded. The absence of min/max data for Low, High, and Ultra means the averages are the only reference, but the trend is clear: the system is capable of high frame rates in less demanding scenes and maintains playable levels in complex scenarios. The 4K Ultra average of 70 FPS is exactly at the threshold for smooth simulation, and users with VRR displays will benefit from the slight fluctuations. Overall, the measured FPS breakdown confirms that this combo is versatile, excelling at 1080p and 1440p while remaining fully playable at 4K, making it a strong choice for flight simulation enthusiasts who want both performance and visual quality.
