Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the data for the Intel Core Ultra 7 265K paired with the AMD Radeon RX 580 paints a clear picture of a system that is heavily constrained by its graphics card. The combination of a modern, high-core-count processor with an older, end-of-life GPU results in a performance profile that is almost entirely dictated by resolution and graphical preset, with the CPU rarely becoming the limiting factor. This analysis will break down the measured frame rates to understand where this combo stands and what it can realistically deliver.

Resolution Scaling

The measured FPS data reveals a steep and predictable performance cliff as resolution increases, which is the primary indicator of a GPU-bound system. At 1920x1080 with Low settings, the combo achieves an average of 54 FPS. This is the peak performance observed in the entire dataset. Moving up to 2560x1440 at the same Low preset, the average FPS drops to 43, a significant reduction of 11 FPS (approximately 20%). This scaling continues as the resolution is pushed to 3840x2160, where the average FPS at Low settings falls to 32. This represents a 22 FPS drop from 1080p, or a 41% reduction in performance.

The pattern becomes even more pronounced at higher graphical settings. At High settings, the average FPS falls from 31 at 1080p to 25 at 1440p and then to 19 at 4K. The delta between 1080p and 4K is 12 FPS, a 39% decline. This consistent and substantial drop across all settings confirms that the rendering resolution is the dominant factor affecting performance. The data implies that the RX 580's pixel throughput and memory bandwidth are being saturated long before the Core Ultra 7 265K's processing capabilities are fully utilized. The GPU is the bottleneck, and its limitations become more severe as the number of pixels requiring shading and texturing increases.

How This Combo Ranks

In the context of all tested hardware combinations for Microsoft Flight Simulator, this setup ranks near the bottom. The combo rank is 3376 out of 3714 total combinations, placing it in the bottom 9% of all tested systems. This low percentile ranking is a direct consequence of the GPU's age and performance class. While the CPU is a top-tier performer in its own right, the pairing with the RX 580 drags the entire system's gaming performance down to a level that is only competitive with much older or lower-end hardware.

The GPU's benchmark data reinforces this position. The Radeon RX 580 sits in the 53rd percentile of all GPUs, with an average benchmark score of 12928. Its nearest rivals in terms of average score include the NVIDIA GeForce GTX 1660 SUPER, which is 0.4% faster, and the NVIDIA GeForce RTX 3050 Ti Mobile, which is 0.1% faster. These are not modern high-end parts; they represent the mid-range of previous generations. This places the RX 580 in a performance tier that is fundamentally unsuited for the heavy demands of a flight simulator at high resolutions, explaining the low overall combo ranking. The data suggests that the CPU is being held back significantly by the GPU in this specific game.

GPU Role

The AMD Radeon RX 580 is clearly the limiting component in this configuration. Its specifications, while once respectable, are outdated for a 2020 title like Microsoft Flight Simulator. The GPU is built on the 14nm process with a GCN 4.0 architecture, featuring 2304 shading units, 144 texture mapping units, and 32 raster output units. It has a base clock of 1257 MHz and a boost clock of 1340 MHz. The memory subsystem consists of 8 GB of GDDR5 on a 256-bit bus, providing a bandwidth of 256.0 GB/s. These figures, particularly the 256-bit bus and 8 GB capacity, are now considered entry-level for modern gaming.

The data shows that this hardware is insufficient for smooth gameplay at higher settings. At 1080p Ultra, the average FPS is just 30, which is on the edge of playability. At 4K Ultra, the average drops to a mere 18 FPS, which is a slideshow. The GPU's compute capabilities, rated at 6.175 TFLOPS for FP32, are simply not enough to handle the complex rendering workload of the simulator at high resolutions and detail levels. The 8 GB of VRAM is also a potential concern, as modern flight simulators with high-resolution textures can easily consume more. The benchmark results show the GPU's Passmark G3D score of 8813, which places it in the 53rd percentile, confirming its mid-range standing.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's capabilities across different settings and resolutions.

1920x1080:

• Low: The average FPS is 54, which is the highest recorded for this combo and offers a playable experience.
• Medium: The average FPS is 42, with a minimum of 36 and a maximum of 48. This is a playable setting with a noticeable improvement in visual quality.
• High: The average FPS drops to 31. This is playable but with a significant performance hit compared to Medium.
• Ultra: The average FPS is 30. This is the lowest at 1080p and is borderline playable, with the minimum FPS likely dipping into the low 20s.

2560x1440:

• Low: The average FPS is 43, which is a playable frame rate, though it requires a significant visual compromise.
• Medium: The average FPS is 34, with a minimum of 29 and a maximum of 39. This is marginal for smooth gameplay.
• High: The average FPS is 25. This is below the threshold for comfortable play.
• Ultra: The average FPS is 24. This is not a playable experience.

3840x2160:

• Low: The average FPS is 32. This is not a smooth experience for a simulator.
• Medium: The average FPS is 25, with a minimum of 21 and a maximum of 29.
• High: The average FPS is 19.
• Ultra: The average FPS is 18.

The data shows a clear trend: only the 1080p resolution with Low or Medium settings provides a consistently playable frame rate above 40 FPS. All other configurations result in average frame rates below 35 FPS, which is generally considered too low for a smooth and immersive flight simulation experience.

CPU Role

The Intel Core Ultra 7 265K is a powerhouse processor that is not being challenged by this game at these settings. Its role in this combo is to provide a stable foundation, ensuring that the GPU is the only bottleneck. The CPU features 20 cores and 20 threads based on the Arrow Lake architecture. Its boost clock of 5.50 GHz ensures high single-threaded performance, which is critical for simulation games that often rely on a primary game thread. The processor's multi-threaded capabilities are also substantial, as evidenced by its Cinebench R23 multi-core score of 35850.

This CPU's performance is in the 94th percentile of all CPUs, with an average benchmark score of 70879. Its nearest rivals include the Intel Core i7-14700KF, which is 1% faster, and the AMD Ryzen 7 9700F, which is 1.3% slower. The Core Ultra 7 265K's 30 MB of shared L3 cache and 102.4 GB/s of memory bandwidth provide ample data throughput for the game's engine. The data strongly suggests that the CPU is not the limiting factor. The frame rate drops observed when increasing resolution or settings are entirely attributable to the GPU's inability to keep up. In this pairing, the CPU is waiting on the GPU, not the other way around.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the user's target resolution and tolerance for frame rate dips. The data indicates that a smooth experience is only achievable at 1080p.

• For 1080p: The Medium preset is the best choice. It delivers an average of 42 FPS with a minimum of 36 FPS, which provides a good balance between visual fidelity and smoothness. The Low preset offers the highest frame rate at 54 FPS, but the visual quality is significantly reduced. The High and Ultra presets, while playable with averages around 30 FPS, will be subject to noticeable stutters and frame drops, especially in dense areas or during complex maneuvers.

• For 1440p: The Low preset is the only one that yields an average FPS above 40. The Medium preset at 34 FPS is borderline, and its minimum FPS of 29 indicates it will not be a consistently smooth experience. High and Ultra presets are not recommended as they fall well below 30 FPS.

• For 4K: None of the settings are recommended for a playable experience. The highest average FPS is 32 at the Low preset, which is still below the threshold for smooth gameplay.

Ultimately, the data suggests that users should stick to 1080p to get the most out of this hardware combination. Choosing the Medium preset at 1080p offers the most stable and visually acceptable experience, while the Low preset is recommended for users who prioritize frame rate above all else.
