Q: Does the game's frame rate scale linearly with resolution?

A: No, the performance drop is not linear. For example, on High settings, the average FPS drops from 28 at 1920x1080 to 22 at 2560x1440, a 21.4% decrease, and then to 16 at 3840x2160, a 42.8% decrease from 1440p. This suggests the GPU is the primary bottleneck, as the frame rate penalty accelerates with the exponential increase in pixel count.

GPU Role

The AMD Radeon 880M is an integrated graphics processor based on the RDNA 3.5 architecture. Its performance in Microsoft Flight Simulator is the single most limiting factor for this system. The GPU's boost clock is listed at 2900 MHz, which is high for an integrated part, but its memory configuration is "System Shared," meaning it relies on the system's main memory. This inherently limits memory bandwidth, which is critical for a game that streams vast amounts of terrain and scenery data.

The benchmark results clearly illustrate this limitation. The GPU's percentile rank of 43 places it in the lower half of all GPUs, and its average benchmark score of 8436 puts it in direct competition with much older discrete mobile GPUs like the NVIDIA GeForce GTX 675MX. In the game itself, the Radeon 880M struggles to produce playable frame rates. At 3840x2160, even on Low settings, it only manages an average of 28 FPS. This suggests that the sheer pixel count at 4K overwhelms the GPU's 768 shading units and 16 ROPs. The data implies that the GPU is capable of processing the game's geometry and effects only at lower resolutions and with reduced graphical fidelity.

The role of the GPU becomes even more apparent when examining the frame rate scaling with settings. At 1920x1080, dropping from Medium to Low yields a 27% performance increase, from 37 FPS to 47 FPS. However, the jump from Low to Ultra is a drastic 44.7% decrease in performance. This pattern is consistent across all resolutions, showing that the GPU's limited processing power and memory bandwidth are quickly saturated by the demands of higher graphical presets. The Radeon 880M is an integrated solution that is fundamentally out of its depth for a simulator of this scale, succeeding only in the most undemanding scenarios.

CPU Role

The Intel Core Ultra 7 155H plays a supporting, yet crucial, role. With 16 cores and 22 threads, and a boost clock of 4.80 GHz, this is a capable mobile processor. Its average benchmark score of 32697 places it in the 83rd percentile of all CPUs, indicating strong multi-threaded performance. The CPU's nearest rivals, such as the Intel Core i5-14600T and AMD Ryzen AI 7 PRO 360, all score within 0.2% of it, confirming its competitive standing.

In the context of Microsoft Flight Simulator, the CPU's job is to handle the complex flight model, AI traffic, and physics calculations. The data suggests that the Core Ultra 7 155H is more than adequate for these tasks. The primary bottleneck is clearly the GPU, as evidenced by the significant frame rate drops when resolution and settings are increased. If the CPU were the limiting factor, we would expect to see less variation in FPS across different resolutions at the same settings, as the CPU's workload would remain relatively constant. Instead, we see a sharp decline in performance as the pixel count increases, which is a classic sign of GPU limitation.

This is not to say the CPU is irrelevant. A slower processor could potentially bottleneck the system, preventing the GPU from reaching its maximum potential. However, in this pairing, the Core Ultra 7 155H has sufficient headroom. The 24 MB of shared L3 cache and high boost clock likely help with the game's single-threaded simulation loop, ensuring that the GPU is fed with data as efficiently as possible. The benchmark results indicate that the CPU is a strong component that is being held back by the integrated graphics solution, rather than the other way around.

Settings Recommendations

Based on the measured FPS data, achieving a consistently smooth experience in Microsoft Flight Simulator with this hardware requires significant compromises. The data suggests that the Low preset is the only viable option for playable frame rates. At 1920x1080, it is the only setting that breaks the 40 FPS barrier, with an average of 47 FPS. This is the recommended starting point for any user looking for a playable experience.

The Medium preset at 1920x1080, with an average of 37 FPS, is a borderline option. It offers a better visual experience than Low, but the frame rate may feel less fluid, especially in dense urban areas or during complex weather events. The min FPS recorded for this setting is 31, which is close to the threshold where simulation games can start to feel less responsive. For users who prioritize visual fidelity over absolute smoothness, this could be a compromise, but the data suggests Low is safer for consistent performance.

All other settings and resolution combinations produce average frame rates in the 16-29 FPS range. These are generally not recommended for a playable experience, as they fall well below the 30 FPS baseline that many consider the minimum for a playable simulator. The High and Ultra presets are particularly demanding and should be avoided at any resolution. The data clearly indicates that the system's performance is too limited for these higher presets, resulting in a slideshow-like experience. In summary, the best experience per the measured rows is unequivocally 1920x1080 with Low settings.

How This Combo Ranks

The ranking of this combo is stark. It is positioned at 2924 out of 2996 tested combinations, which places it in the 2.4th percentile. This means that in our database, 97.6% of tested CPU-GPU pairings deliver better performance in Microsoft Flight Simulator. This is a crucial data point that contextualizes the system's capabilities. It is not a mid-range or entry-level performer; it is at the very bottom of the performance spectrum for this specific game.

This low ranking is almost entirely attributable to the AMD Radeon 880M. The GPU's average benchmark score of 8436 places it in the 43rd percentile, but its performance in this specific title is far worse relative to other components. The combination of a powerful CPU like the Core Ultra 7 155H with a weak integrated GPU creates a significant imbalance. The CPU is in the 83rd percentile, but it is paired with a GPU that, in this game, performs like a component from a much lower tier.

The ranking highlights the fact that for Microsoft Flight Simulator, the GPU is the dominant factor in determining overall system performance. The Core Ultra 7 155H's strong benchmark scores and high percentile rank are effectively negated by the Radeon 880M's inability to render the game's complex scenes at an acceptable speed. This combo serves as a clear example of how a powerful processor cannot compensate for a weak graphics solution in a GPU-intensive title.

Measured FPS Breakdown

The following breakdown details the exact average frame rates measured for each resolution and settings combination.

3840x2160 (4K)

• Ultra: The average FPS is 16.
• High: The average FPS is 16.
• Medium: The average FPS is 22, with a minimum of 18 and a maximum of 25.
• Low: The average FPS is 28.

2560x1440 (1440p)

• Ultra: The average FPS is 21.
• High: The average FPS is 22.
• Medium: The average FPS is 29, with a minimum of 25 and a maximum of 34.
• Low: The average FPS is 38.

1920x1080 (1080p)

• Ultra: The average FPS is 26.
• High: The average FPS is 28.
• Medium: The average FPS is 37, with a minimum of 31 and a maximum of 42.
• Low: The average FPS is 47.

The data shows a consistent trend. At every resolution, the frame rate increases as the settings are lowered. The most substantial jump is generally seen when moving from Medium to Low settings. For instance, at 1080p, this change yields a 27% increase in average FPS. The difference between High and Ultra is minimal, often only 1-2 FPS, indicating that the Ultra preset adds significant graphical load without a proportional visual return for this hardware.

Resolution Scaling

The way frame rates scale with resolution provides a definitive answer to the question of which component is the bottleneck. When the resolution is increased, the GPU must render a larger number of pixels. The CPU's workload, however, remains relatively stable. Therefore, if the CPU were the primary bottleneck, we would expect the frame rate to remain somewhat consistent across resolutions.

The data shows the opposite. On Low settings, the average FPS drops from 47 at 1920x1080 to 38 at 2560x1440 and then to 28 at 3840x2160. This is a clear and significant decline. The frame rate drops by 19.1% from 1080p to 1440p, and then by another 26.3% from 1440p to 4K. This accelerating decline is a textbook indicator of a GPU bottleneck. The Radeon 880M is simply unable to handle the increasing pixel throughput.

This pattern is consistent across all settings. For example, on Medium settings, the average FPS is 37 at 1080p, 29 at 1440p, and 22 at 4K. The consistent and substantial drop in performance with each resolution increase confirms that the AMD Radeon 880M is the limiting component. The Intel Core Ultra 7 155H has ample processing power to feed the GPU, but the GPU's rendering capabilities are exhausted long before the CPU's potential is reached. The data implies that lowering the resolution is the most effective way to improve performance, as it directly reduces the strain on the integrated graphics processor.
