Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title, and the data for the AMD Ryzen 5 5600 + Intel Arc B580 combination shows a system that is consistently capable but requires careful settings management to achieve smooth frame rates, especially at higher resolutions. The measured results indicate a clear performance hierarchy that shifts depending on whether the CPU or GPU is the primary bottleneck.

Resolution Scaling

The frame rate drop from 1080p to 4K is significant and reveals the GPU as the primary limiting factor in this pairing. At Low settings, the average FPS falls from 95.7 at 1920x1080 to 79.5 at 2560x1440, a reduction of roughly 17%, and then further down to 54.9 at 3840x2160. This represents a total performance loss of about 43% from 1080p to 4K. The pattern is consistent across all settings presets. At High settings, the average drops from 55.8 FPS at 1080p to 47.2 at 1440p and finally to 32.3 at 4K, a 42% decline from the baseline. This steep scaling curve strongly suggests that the Intel Arc B580’s rendering capabilities are being saturated as pixel count increases, which is typical for a GPU with a 192-bit memory bus and 456.0 GB/s of bandwidth.

The scaling between 1440p and 4K is particularly steep, indicating that the GPU is working much harder in this range. For instance, at Medium settings, the 1440p result is 60.9 FPS, but the 4K result drops to 45.4 FPS, a 25% performance hit. This non-linear drop is a classic sign of the GPU running out of fill rate and memory bandwidth. The data shows that 1080p is the most comfortable resolution for this combo, allowing for high frame rates even at higher presets, while 4K pushes the system to its limits, making even Low settings a compromise for playability.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the AMD Ryzen 5 5600 and Intel Arc B580 ranks at 1399 out of 1795 combos for Microsoft Flight Simulator. This places it in the lower-mid tier of all tested systems, meaning that while it is not a top-tier performer, it is far from the bottom. The ranking suggests that this combination is not optimized for the extreme demands of this simulator, which often favors both high single-thread CPU performance and substantial GPU memory and bandwidth.

The CPU’s overall benchmark percentile is 79, meaning it performs better than 79% of all tested processors, yet the combo’s ranking in this specific game is lower than this percentile might suggest. This indicates that Microsoft Flight Simulator is particularly sensitive to the GPU’s capabilities, which is consistent with the resolution scaling data that shows the GPU as the bottleneck. The GPU itself has a percentile of 66, which aligns more closely with the combo’s overall rank. The data shows that while the CPU is a strong performer in general, the GPU’s relative standing is what drags the combo down in this specific title, resulting in a rank that is 604 places from the top.

CPU Role

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.50 GHz and a boost clock of 4.40 GHz. In synthetic benchmarks, it shows strong single-thread performance with a 3dmark single-thread score of 882 and a Cinebench R23 single-core score of 2584. This is crucial for Microsoft Flight Simulator, which is known to be heavily dependent on single-core performance for its main simulation loop. The CPU’s multi-threaded capabilities are also solid, as evidenced by a Cinebench R23 multi-core score of 18309, which helps with background tasks and complex scenery loading.

However, the benchmark data from the game itself suggests that the CPU is not the primary constraint in this pairing. The fact that frame rates drop so significantly with resolution increases points to the GPU being the limiting factor. The CPU has enough headroom to feed the GPU at lower resolutions, but as the GPU becomes saturated at higher resolutions, the CPU’s role diminishes. The 32 MB of shared L3 cache is beneficial for game data, but it does not compensate for the GPU’s limitations in this title. In this context, the Ryzen 5 5600 provides a stable foundation, but the system’s overall performance is dictated by what the Arc B580 can render.

Measured FPS Breakdown

The measured data provides a clear picture of performance across different settings and resolutions. At 1920x1080, the system achieves 95.7 FPS on Low, 73 FPS on Medium, 55.8 FPS on High, and 56 FPS on Ultra. The jump from Low to Medium is a 24% performance drop, while the drop from Medium to High is another 24%, showing that each preset tier has a significant cost. Interestingly, the High and Ultra presets yield nearly identical average frame rates, with High at 55.8 and Ultra at 56.0, suggesting that the Ultra preset’s additional graphical features are not heavily taxing the GPU at this resolution, or that the CPU is beginning to become a limiting factor.

At 2560x1440, the scores are 79.5 FPS on Low, 60.9 FPS on Medium, 47.2 FPS on High, and 40.5 FPS on Ultra. The scaling here is more predictable, with a consistent drop of about 20-25% for each preset level. The 1440p Low setting remains very playable, while High and Ultra dip below the 60 FPS threshold. At 3840x2160, the results are 54.9 FPS on Low, 45.4 FPS on Medium, 32.3 FPS on High, and 33.9 FPS on Ultra. The performance at 4K is marginal at best, with even the Low preset struggling to maintain a smooth 60 FPS. The inversion where Ultra (33.9) slightly beats High (32.3) at 4K is notable and may be due to driver optimizations or specific rendering paths within the simulator.

GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture and features 12 GB of GDDR6 memory on a 192-bit bus, providing 456.0 GB/s of bandwidth. It has a base and boost clock of 2670 MHz and a FP32 performance of 13.67 TFLOPS. The 12 GB VRAM is a key asset for Microsoft Flight Simulator, which can consume large amounts of memory for high-resolution textures. The data suggests that the GPU is the definitive bottleneck in this system, particularly at higher resolutions. The significant frame rate drops from 1440p to 4K are directly attributable to the GPU’s rendering limits.

The GPU’s performance in synthetic benchmarks is modest, with a Passmark G3D score of 15748 and a 3dmark Steel Nomad DX12 score of 3068. These scores place it in the 66th percentile of all GPUs. In the context of this game, the GPU’s relative weakness is exposed. The frame rate differences between Low and Ultra settings at any given resolution are substantial, but the absolute numbers remain low at 4K. This indicates that while the GPU has enough memory for the game’s assets, it lacks the raw compute power and memory bandwidth to push high frame rates at high resolutions, making it the clear component that limits the overall experience.

Settings Recommendations

Based on the measured data, the best experience for this combo depends heavily on the target resolution. For 1080p gameplay, the High preset at 55.8 FPS is the sweet spot, offering a good balance of visual fidelity and playable frame rates. The Ultra preset at 56 FPS provides virtually the same performance, so users can essentially enable Ultra for free at this resolution, if they prefer the extra visual effects. For those prioritizing smoothness over visuals, the Medium preset at 73 FPS is an excellent choice, ensuring a comfortable margin above 60 FPS.

At 1440p, the Low preset at 79.5 FPS is the only one that consistently delivers a smooth experience. The Medium preset at 60.9 FPS is borderline playable, but may experience occasional dips. The High and Ultra presets, at 47.2 and 40.5 FPS respectively, are not recommended for a fluid experience and should be avoided. For 4K, the data shows that no preset provides a truly smooth experience. The Low preset at 54.9 FPS is the highest achievable average, but it still falls short of a 60 FPS target. Users who insist on 4K should expect to run at Low settings and accept a less fluid result, or consider lowering the resolution. The most practical advice is to target 1080p with High or Ultra settings for the best combination of visual quality and performance, or 1440p with Low settings for a smoother frame rate.
