Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding flight simulation title that stresses both processor and graphics hardware heavily. The AMD Ryzen 5 2600 and AMD Radeon RX 580 combination produces a playable experience only at lower settings and resolutions, with benchmark results indicating that the GPU is the primary bottleneck in most configurations. This analysis examines the measured FPS data to determine the role of each component and the optimal settings for this pairing.

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

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen architecture, with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. It belongs to the 2000 series and is built on a 12 nm process node at GlobalFoundries. The processor features a 16 MB shared L3 cache and dual-channel DDR4 memory support, with a memory bandwidth of 46.9 GB/s. In synthetic benchmarks, this CPU achieves a Cinebench R23 multi-core score of 11186 and a single-core score of 1579, placing it in the 77th percentile of all CPUs tested.

In Microsoft Flight Simulator, the CPU’s role is significant due to the game’s complex flight models and scenery generation. The measured FPS data shows that at 1080p with Low settings, the system reaches 53.1 FPS, which is the highest average across all tested configurations. This suggests that the CPU is capable of feeding the GPU adequately at lower graphical loads. However, when comparing to its nearest rivals in synthetic benchmarks, the Ryzen 5 2600 sits within a narrow performance band: it trails the Intel Core i5-1345U by 0.4% and the Intel Core i5-11600KF by 0.6%, while leading the AMD Ryzen 5 7530U by 0.6% and the Intel Core i7-10700F by 0.7%. These deltas are minimal, indicating that this CPU’s compute performance is competitive with those chips, but the game’s demands may still limit frame rates in CPU-heavy scenarios.

The 12 threads and 6 cores provide sufficient parallel processing for the game’s simulation logic, but the single-thread performance, reflected in a Cinebench R20 single-core score of 663, may constrain performance in scenarios that rely heavily on a single main thread. The benchmark results indicate that the CPU is not the primary limiter at higher resolutions, as FPS scales down consistently with increased GPU load, which points to the graphics card becoming the dominant factor.

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

The AMD Radeon RX 580 is a Polaris 20 chip built on a 14 nm process, featuring 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. Its base clock is 1257 MHz with a boost clock of 1340 MHz, and memory runs at 2000 MHz (8 Gbps effective). The GPU has 2304 shading units, 144 texture mapping units, and 32 raster operation units, delivering a peak FP32 performance of 6.175 TFLOPS. In synthetic benchmarks, the RX 580 scores 8813 in Passmark G3D and 52176 in Geekbench Metal, placing it in the 53rd percentile of all GPUs.

In Microsoft Flight Simulator, the GPU’s VRAM capacity and bandwidth are critical for handling high-resolution textures and complex scenery. The measured FPS data clearly shows that the RX 580 struggles at higher settings and resolutions. At 4K Ultra, the average FPS drops to 16.7, while at 1080p Ultra it reaches 31.2 FPS. This pattern indicates that the GPU is the limiting component, as reducing resolution from 4K to 1080p at the same settings yields significant FPS gains. For example, at High settings, moving from 3840x2160 (19.3 FPS) to 1920x1080 (31.4 FPS) improves performance by roughly 62%, which is consistent with a GPU-bound scenario.

Comparing the RX 580 to its nearest rivals in synthetic benchmarks shows it is nearly identical to the NVIDIA GeForce GTX 570 (0% delta) and GTX 950 (0.1% delta), while leading the AMD Radeon Pro 455 by 1.1% and trailing the NVIDIA P106-090 by 1.1%. These small deltas suggest that the RX 580’s raw compute is on par with those older cards, but its 8 GB VRAM and 256-bit memory bus provide an advantage in texture-heavy titles like Microsoft Flight Simulator, where memory capacity can prevent stutter or texture pop-in.

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

Based on the measured FPS data, the optimal experience for this combination depends heavily on the target resolution. At 1080p, the Low preset delivers 53.1 FPS, which is the only configuration that approaches a smooth 60 FPS threshold. The Medium preset at 1080p yields 43.2 FPS, while High and Ultra produce 31.4 and 31.2 FPS respectively. The data indicates that the jump from Low to Medium costs roughly 19% performance, while the jump from Medium to High costs another 27%, making Low the most responsive choice for gameplay fluidity.

At 1440p, the Low preset achieves 46.1 FPS, which is still playable but requires a significant compromise in visual quality. The Medium preset drops to 32.4 FPS, and High/Ultra fall below 23 FPS, which may be too stuttery for a flight simulator where precise control is needed. At 4K, only Low reaches 29.6 FPS, while Medium (24.1), High (19.3), and Ultra (16.7) all fail to provide a consistent experience. For a balanced approach, 1080p Low is the recommended preset, as it offers the highest frame rate and avoids the steep performance penalties seen at higher settings. Users prioritizing visuals over frame rate might consider 1080p Medium, but the data suggests that the RX 580’s compute limitations make Low the only viable option for smooth operation.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific configuration, pairing the AMD Ryzen 5 2600 with the AMD Radeon RX 580, ranks 1670 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the bottom 7% of all combinations, indicating that it is a below-average performer for this title. The rank reflects the cumulative impact of the CPU’s mid-tier compute and the GPU’s aging architecture, which together cannot handle the game’s demanding rendering workload at higher settings.

The low ranking is consistent with the measured FPS data, which shows that even at 1080p Low, the system only reaches 53.1 FPS, far from the maximum refresh rates of modern monitors. The combo’s position suggests that most other tested configurations, likely featuring newer CPUs and GPUs, outperform it by a substantial margin. The data also implies that the bottleneck is primarily the GPU, as the CPU’s synthetic scores are within 1% of several rival processors, yet the overall combo rank remains poor due to the RX 580’s limited capability in this specific game.

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

The measured FPS data across resolutions reveals a clear scaling pattern that identifies the limiting component. At Low settings, the average FPS drops from 53.1 at 1080p to 46.1 at 1440p (a 13% reduction) and then to 29.6 at 4K (a 44% reduction from 1440p). This non-linear drop indicates that the GPU is the primary bottleneck, as the pixel count increases more sharply at higher resolutions, overwhelming the RX 580’s shading and memory bandwidth capabilities.

At Medium settings, the scaling is steeper: 43.2 FPS at 1080p falls to 32.4 FPS at 1440p (a 25% drop) and then to 24.1 at 4K (a 26% drop from 1440p). Similarly, at High settings, 31.4 FPS at 1080p drops to 23.0 at 1440p (a 27% drop) and then to 19.3 at 4K (a 16% drop). The diminishing percentage drops at higher resolutions for High and Ultra settings suggest that the GPU is already saturated, and additional pixel count has a smaller relative impact because the frame rate is already low.

This scaling behavior confirms that the CPU is not the limiting factor, as a CPU-bound scenario would show minimal FPS changes across resolutions. Instead, the consistent FPS reductions with increased resolution point directly to the GPU’s compute throughput and memory bandwidth as the constraining elements. The RX 580’s 256.0 GB/s bandwidth and 6.175 TFLOPS FP32 performance are simply insufficient for Microsoft Flight Simulator’s heavy shader and texture loads at higher resolutions, particularly when settings are elevated.
