Microsoft Flight Simulator

Microsoft Flight Simulator is an unusually demanding title, and the measured data for the AMD Ryzen 9 8945HX with the NVIDIA GeForce RTX 5060 shows a system that is firmly balanced around the GPU at higher resolutions, while the CPU’s substantial thread count provides a solid foundation for the simulator’s complex simulation logic. The combination ranks 1956th out of 2996 tested combos in this game, placing it in the lower half of the database, yet the actual frame rates are playable at 1080p and 1440p with adjusted settings. The data indicates that this is a capable mobile platform for Microsoft Flight Simulator, but users must accept compromises at 4K, where even Low settings only reach an average of 61 FPS and Ultra dips to 34 FPS. Benchmark results show a clear hierarchy: the CPU is not the primary bottleneck at 4K, but at 1080p Low, the system achieves 103 FPS, suggesting the processor can feed the GPU adequately when the load is lightened.

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

The AMD Ryzen 9 8945HX is a 16-core, 32-thread mobile processor built on the Zen 4 architecture, with a base clock of 2.50 GHz and a boost clock of 5.40 GHz. This is a high-end part, evidenced by its 95th percentile ranking against all CPUs in the database, and its multi-threaded capabilities are substantial: Cinebench R23 multi-core score is 42713, while the single-core score is 6030. In Microsoft Flight Simulator, which is known for heavy simulation workloads that scale with core count, this processor provides ample headroom. The data shows that at 1080p Low, the system reaches 103 FPS average, which is the highest measured result across all settings and resolutions. This suggests that the CPU can handle the game’s physics and flight model calculations without becoming a limiting factor at lower graphical loads.

However, the relationship between CPU performance and this game’s results is not linear. At 1080p Ultra, the average FPS drops to 58, which is only 5 FPS lower than 1080p High (60 FPS). This small gap between High and Ultra at 1080p indicates that the GPU is already becoming a constraint at these settings, even with a powerful CPU. The Ryzen 9 8945HX’s 64 MB of L3 cache and dual-channel DDR5 memory support (with 83.2 GB/s bandwidth) are relevant for a simulator that constantly streams terrain and aircraft data. The benchmark scores reinforce this: PassMark multi-thread score is 51405, and the average benchmark score is 76212, which is nearly identical to the Intel Core Ultra 9 285HX (76155, delta 0.1%). This near-tie in synthetic benchmarks suggests that in CPU-bound scenarios, the Ryzen 9 8945HX performs on par with its closest rival, but the measured FPS data shows that in this specific game, the GPU takes over as the primary performance driver beyond 1080p.

The CPU’s single-thread performance is also critical for flight simulators, which often have a main simulation thread. The Cinebench R23 single-core score of 6030 is strong, and the PassMark single-thread score of 3907 places it well above average. Yet, the measured FPS scaling tells the real story: going from 1080p Low (103 FPS) to 1080p High (60 FPS) is a 43 FPS drop, which is a massive reduction caused by increased GPU load, not CPU limitations. At 1440p, the pattern continues: Low (83 FPS) to High (49 FPS) is a 34 FPS drop. This indicates that the CPU is not the bottleneck; rather, the RTX 5060’s rendering workload dictates the frame rate. The Ryzen 9 8945HX’s 16 cores and 32 threads are more than sufficient for Microsoft Flight Simulator’s CPU demands, and the data confirms that at no resolution does the processor prevent the GPU from reaching its potential. The percentile rank of 95 for all CPUs, combined with a Cinebench R20 multi-core score of 17939, supports the conclusion that this CPU is overqualified for the game’s CPU requirements, leaving the GPU as the decisive component.

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

Based on the measured FPS data, the optimal settings for this CPU-GPU combination depend heavily on the target resolution and desired frame rate. At 1920x1080, the Medium preset provides the best balance: an average of 80 FPS with a minimum of 68 FPS and a maximum of 92 FPS. This is a smooth, playable experience for a flight simulator, where consistent frame times matter more than peak FPS. High settings at 1080p drop to 60 FPS average, which is still playable but leaves less headroom for complex scenes with dense scenery or weather effects. Ultra at 1080p averages 58 FPS, which is only 2 FPS lower than High, making the jump to Ultra minimally impactful on performance while likely adding visual fidelity. However, the Medium preset’s 80 FPS average is 20 FPS higher than High, a significant margin that justifies the visual compromise for smoother flight.

For 2560x1440, Medium is again the recommended preset, delivering 65 FPS average with a minimum of 55 FPS and a maximum of 74 FPS. This is a playable frame rate for a simulator, though users sensitive to stutter might prefer Low, which hits 83 FPS average. High at 1440p drops to 49 FPS, which is below the 60 FPS threshold that many consider the baseline for smooth gameplay. Ultra at 1440p is the worst option at 46 FPS, making it unsuitable for sustained flight. The data shows that Medium at 1440p offers a 16 FPS advantage over High, a substantial improvement that makes Medium the clear choice for this resolution.

At 3840x2160, the situation is more constrained. Low settings are the only preset that achieves an average above 60 FPS, hitting 61 FPS. Medium averages 48 FPS with a minimum of 41 FPS, which is borderline playable but may suffer during heavy loads. High averages 36 FPS, and Ultra drops to 34 FPS, both of which are too low for a smooth experience. Therefore, at 4K, the recommendation is to use Low settings if playability is the priority, or Medium if the user can tolerate occasional dips below 45 FPS. The measured data shows a clear pattern: Medium is the best compromise across 1080p and 1440p, while Low is the only viable option at 4K for maintaining 60 FPS. The minimum FPS values for Medium at all resolutions (68 at 1080p, 55 at 1440p, 41 at 4K) indicate that this preset provides the most stable frame pacing relative to its average, making it the safest choice for a simulator where sudden drops can disrupt immersion.

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

The measured FPS data reveals a steep resolution scaling curve that clearly identifies the GPU as the limiting component. At Low settings, the average FPS drops from 103 at 1080p to 83 at 1440p (a 20 FPS reduction, or roughly 19%) and then to 61 at 4K (a further 22 FPS reduction, or about 27% from 1440p). This progressive decline is typical of a GPU-bound scenario, where increasing pixel count directly increases the rendering workload. The CPU’s role remains constant across resolutions, so the fact that FPS falls so sharply from 1080p to 4K indicates that the RTX 5060 cannot keep up with the pixel throughput demands.

At High settings, the drop is even more pronounced: 60 FPS at 1080p, 49 FPS at 1440p, and 36 FPS at 4K. The 24 FPS difference between 1080p and 4K at High settings (a 40% reduction) shows that higher graphical fidelity amplifies the GPU bottleneck. Similarly, at Ultra settings, the averages are 58 FPS (1080p), 46 FPS (1440p), and 34 FPS (4K), a 24 FPS or 41% drop from 1080p to 4K. The pattern is consistent: as resolution increases, the frame rate drops by roughly 20-25 FPS per step, regardless of the preset, which is a strong indicator that the GPU is the limiting component.

If the CPU were the primary bottleneck, the FPS would remain relatively flat across resolutions, or the drop would be less severe. The data contradicts that hypothesis. For example, at Low settings, 1080p achieves 103 FPS, but the CPU is not maxed out because 1440p still yields 83 FPS—a significant difference. The Ryzen 9 8945HX’s high multi-core and single-core scores (Cinebench R23 multi-core 42713, single-core 6030) suggest it can handle the game’s simulation load at any resolution, but the RTX 5060’s specifications tell the story: 8 GB of GDDR7 memory on a 128-bit bus with 448.0 GB/s bandwidth, and a 3DMark Steel Nomad DX12 score of 3628. These are modest figures for a modern GPU, and the resolution scaling confirms that the GPU is the limiting factor.

The only anomaly is at 1080p Ultra, where the average is 58 FPS, just 2 FPS below High. This suggests that at 1080p, the game begins to approach a CPU or memory bandwidth ceiling, but the effect is minimal. Overall, the resolution scaling data points to a system where the GPU is the constraining component, and users should prioritize lowering graphical settings or resolution to achieve higher frame rates, rather than relying on CPU upgrades.

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

The NVIDIA GeForce RTX 5060 is built on the Blackwell 2.0 architecture with a 5 nm process, featuring a base clock of 2280 MHz and a boost clock of 2497 MHz. It has 8 GB of GDDR7 memory on a 128-bit bus, providing 448.0 GB/s of bandwidth. These specifications are modest for a 2025 GPU, and the measured FPS data in Microsoft Flight Simulator reflects this. The GPU’s PassMark G3D score is 20891, and its 3DMark Steel Nomad DX12 score is 3628, placing it in the 72nd percentile of all GPUs. In this game, the RTX 5060 is the primary bottleneck, as evidenced by the resolution scaling analysis. The 8 GB VRAM is particularly concerning for a flight simulator that streams vast amounts of terrain and aircraft textures, and the data shows that at 4K Ultra, the average FPS drops to 34, likely due to both VRAM capacity and bandwidth limitations.

The GPU’s clock speeds and memory bandwidth directly influence the measured results. At 1080p Low, the system achieves 103 FPS, which indicates that the RTX 5060 can handle lighter loads easily. However, as settings increase, the frame rate falls rapidly: High at 1080p is 60 FPS, Medium is 80 FPS, and Ultra is 58 FPS. The small difference between High and Ultra (2 FPS) suggests that the GPU’s shading units (3840) and texture mapping units (120) are being saturated, and the 48 ROPs may limit pixel throughput at higher quality settings. The RTX 5060’s FP32 performance is 19.18 TFLOPS, which is adequate for 1080p but insufficient for 4K with high settings. The GPU’s nearest rivals include the AMD Radeon 860M (average score 26401, delta -0.3%) and the NVIDIA GeForce MX550 (26421, delta -0.3%), which are both integrated or low-end discrete GPUs, highlighting that the RTX 5060 is positioned at the lower end of the discrete GPU market.

The GPU’s memory bandwidth of 448.0 GB/s is a critical factor in Microsoft Flight Simulator, which requires constant data streaming for scenery. At 4K, the bandwidth becomes a bottleneck, as evidenced by the steep FPS drop from 1080p to 4K. The 3DMark Steel Nomad score of 3628 is a synthetic indicator of DX12 performance, and in practice, the game’s average FPS at 1440p High (49) and 4K High (36) confirms that the GPU is struggling to maintain playable frame rates at higher resolutions. The RTX 5060’s passmark DirectX 12 score of 77 is notably low, further indicating that the GPU’s DX12 path is not its strength. Overall, the GPU role in this system is to provide playable performance at 1080p and 1440p with Medium settings, while 4K requires significant compromises.

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

The measured FPS data provides a comprehensive picture of this system’s performance across three resolutions and four settings presets. At 1920x1080, the results are as follows: Low averages 103 FPS, Medium averages 80 FPS (with a minimum of 68 and maximum of 92), High averages 60 FPS, and Ultra averages 58 FPS. The progression from Low to Ultra shows a 45 FPS drop, with the largest single step being from Low to Medium (23 FPS), followed by Medium to High (20 FPS). The High to Ultra step is only 2 FPS, indicating diminishing returns at the highest preset. These numbers suggest that 1080p is the most forgiving resolution for this GPU, with even High settings achieving 60 FPS, which is a common target for flight simulation.

At 2560x1440, the averages are: Low at 83 FPS, Medium at 65 FPS (minimum 55, maximum 74), High at 49 FPS, and Ultra at 46 FPS. The drop from 1080p to 1440p is consistent across settings: Low falls by 20 FPS, Medium by 15 FPS, High by 11 FPS, and Ultra by 12 FPS. This indicates that the GPU’s pixel processing capabilities are being taxed more heavily at 1440p, but Medium still provides a playable 65 FPS average. The minimum FPS of 55 at Medium is noteworthy, as it suggests that the game can maintain near-60 FPS even in demanding scenes. High and Ultra at 1440p both fall below 50 FPS, making them less suitable for smooth gameplay.

At 3840x2160, the averages are: Low at 61 FPS, Medium at 48 FPS (minimum 41, maximum 55), High at 36 FPS, and Ultra at 34 FPS. The 4K resolution severely impacts performance, with only Low settings crossing the 60 FPS threshold. The drop from 1440p to 4K is significant: Low falls by 22 FPS, Medium by 17 FPS, High by 13 FPS, and Ultra by 12 FPS. The Medium preset’s minimum of 41 FPS indicates that even the mid-range settings can produce stutter during complex scenes. High and Ultra at 4K are essentially unplayable for a simulator, as 36 and 34 FPS averages will result in noticeable judder. The measured data across all resolutions shows a clear pattern: the RTX 5060 is capable of 60+ FPS at 1080p and 1440p with Medium settings, but 4K requires Low settings to maintain a playable frame rate, and even then, the 61 FPS average is barely above the threshold. These exact numbers provide a definitive guide for users seeking to optimize their experience with this specific CPU-GPU combination.
