Microsoft Flight Simulator

The benchmark data for Microsoft Flight Simulator with the AMD Ryzen 5 5600X and Intel Arc B580 reveals a pairing that is heavily constrained by the graphics card at higher resolutions, yet shows surprising CPU headroom at lower settings. The measured results position this combination as a mid-pack contender for a flight sim known for its demanding rendering loads.

Resolution Scaling

The performance drop from 1080p to 4K is steep and clearly demonstrates where the bottleneck lies. At Low settings, the average frame rate falls from 97.2 FPS at 1920x1080 to 77.4 FPS at 2560x1440, a reduction of roughly 20%. Pushing further to 3840x2160 yields 56.9 FPS, which is a 41% decrease from the 1080p result. This scaling pattern indicates that the Intel Arc B580 is the limiting component once the resolution increases, as the pixel throughput demands outpace what the GPU can deliver.

The trend is consistent across all quality presets. At High settings, the drop from 54.9 FPS at 1080p to 48.0 FPS at 1440p is a 12.5% loss, but the jump to 4K brings a more severe 35% reduction down to 31.7 FPS. The Ultra preset shows the most dramatic scaling penalty: 51.3 FPS at 1080p falls to 41.9 FPS at 1440p, and then plummets to 28.4 FPS at 4K. This represents a 44.6% total loss from the lowest tested resolution to the highest.

Interestingly, the scaling between 1440p and 4K is consistently more punishing than the step from 1080p to 1440p. For example, Medium settings go from 74.2 FPS at 1080p to 58.7 FPS at 1440p (a 20.9% drop), but then to 44.7 FPS at 4K (a 23.8% further drop). This nonlinear behavior suggests that the Arc B580's 192-bit memory bus and 456.0 GB/s bandwidth become progressively more strained as the frame buffer requirements grow with resolution.

GPU Role

The Intel Arc B580 operates with a base clock of 2670 MHz and a boost clock of 2670 MHz, which are identical values, indicating a fixed operating point under load. The GPU is built on the Xe2-HPG architecture and features 12 GB of GDDR6 memory on a 192-bit bus. This memory configuration provides a bandwidth of 456.0 GB/s, which is a critical resource for a game like Microsoft Flight Simulator that streams vast terrain and scenery data.

The 12 GB frame buffer is likely sufficient for the tested scenarios, given that the game's Ultra preset at 4K still achieved playable, if not smooth, frame rates. The real constraint appears to be raw compute throughput. With an FP32 performance of 13.67 TFLOPS and a pixel rate of 213.6 GPixel/s, the B580 struggles to maintain high frame rates at 4K Ultra, where the average dips to 28.4 FPS. The GPU's 2560 shading units and 80 ROPs are tasked with rendering the complex geometry and lighting of the flight simulator, and the data shows that this workload is too heavy for the higher resolution and quality combination.

The GPU's percentile ranking of 66 against all GPUs, with an average benchmark score of 23021, places it in the upper-middle tier. Its nearest rival, the NVIDIA GeForce RTX 4060, scores 23181, which is a 0.7% deltaPct advantage for the NVIDIA card. This slim margin in synthetic benchmarks translates to the observed real-world performance, where the B580 is capable but not exceptional in this specific title.

How This Combo Ranks

The combined configuration of the Ryzen 5 5600X and Arc B580 ranks 1423 out of 1795 tested combos for Microsoft Flight Simulator. This places it in the 21st percentile of all tested pairings, meaning that roughly 79% of combinations deliver better average performance in this game. The ranking reflects a fundamental imbalance: the CPU is a strong performer, but the GPU holds the combo back.

The Ryzen 5 5600X itself sits in the 78th percentile against all CPUs, with an average benchmark score of 20680. Its nearest rivals include the AMD Ryzen 5 5600GT with a deltaPct of -0.3 and the Intel Core i7-10700 also at -0.3, indicating that the 5600X is essentially performance-equivalent to those chips. The Intel Core i5-12490F is 0.5% slower, while the Intel Xeon 6325P is 0.7% faster. These small deltas show that the CPU is not the source of the combo's low ranking.

In contrast, the Arc B580's nearest rival, the RTX 4060, has an average score that is 0.7% higher. The combo rank being in the bottom quarter suggests that while each component is individually competent, the pairing does not synergize well for this particular simulator. The game's heavy reliance on GPU rasterization and shading means that the B580's mid-tier position becomes the decisive factor, dragging the overall combo down the rankings.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the results show a wide spread across presets. Low settings deliver 97.2 FPS, which is the highest average in the entire dataset. Medium settings drop to 74.2 FPS, a 23.7% reduction. High settings yield 54.9 FPS, and Ultra produces 51.3 FPS. The gap between High and Ultra is only 3.6 FPS, suggesting that the Ultra preset's additional effects have diminishing returns at this resolution.

Moving to 2560x1440, the frame rates become more constrained. Low settings produce 77.4 FPS, which is still smooth for a flight sim. Medium settings deliver 58.7 FPS, High drops to 48.0 FPS, and Ultra falls to 41.9 FPS. The relative ordering remains consistent, but the margin between Low and Ultra narrows to 35.5 FPS, compared to 45.9 FPS at 1080p. This compression indicates that the GPU is becoming the limiting factor across all presets.

At 3840x2160, the results are marginal for smooth gameplay. Low settings achieve 56.9 FPS, which is playable. Medium settings produce 44.7 FPS, High drops to 31.7 FPS, and Ultra falls to 28.4 FPS. The Ultra result is below the 30 FPS threshold that many consider the minimum for a playable experience in a slow-paced simulator. The difference between High and Ultra at 4K is only 3.3 FPS, further confirming that the GPU is saturated and additional settings have little impact.

Settings Recommendations

For 1080p displays, the Low preset at 97.2 FPS provides the smoothest experience, but the Medium preset at 74.2 FPS offers a better balance of visual quality and performance. High at 54.9 FPS remains usable, while Ultra at 51.3 FPS is not worth the extra load given the minimal improvement over High.

At 1440p, the Low preset delivers 77.4 FPS and is the only setting that clears the 60 FPS threshold comfortably. Medium at 58.7 FPS is close to that target and likely provides a better visual experience. High at 48.0 FPS is acceptable for a flight simulator, where frame rates above 30 are generally tolerable. Ultra at 41.9 FPS is the least recommended, as the visual gains over High are marginal.

For 4K resolution, the data strongly suggests sticking to Low or Medium settings. Low at 56.9 FPS is the only preset that approaches smoothness, while Medium at 44.7 FPS remains playable. High at 31.7 FPS is borderline, and Ultra at 28.4 FPS should be avoided. The 12 GB VRAM is not the constraint here; rather, the GPU's compute throughput limits the experience. Users targeting 4K should prioritize the Medium preset to maintain a stable frame rate while retaining some visual fidelity. The combination of the Ryzen 5 5600X's strong single-thread performance and the Arc B580's mid-range capabilities means that the CPU will rarely be the bottleneck, so users should focus their settings adjustments on GPU-heavy options like shadow quality and terrain detail.
