Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the data for the AMD Ryzen 5 2600 combined with the AMD Radeon RX 6800 XT reveals a system that is consistently capable, yet heavily influenced by both resolution and the game's notoriously variable workload. The measured frame rates show a configuration that can deliver smooth, immersive flight, but the margins between settings presets and resolutions tell a clear story about where the bottlenecks lie.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 is where the most dramatic performance shift occurs, clearly indicating a growing reliance on the GPU. At 1920x1080 with High settings, the system produces an average of 91 FPS. Moving to 2560x1440 drops that figure to 71.2 FPS, a 21.8% reduction. The jump to 3840x2160 further reduces the average to 51.5 FPS, a 43.4% drop from the 1080p baseline. This scaling pattern is typical for a game that becomes increasingly pixel-bound at higher resolutions.

However, the scaling is not uniform across all settings presets. When examining the Low preset, the frame rate drop from 1080p to 4K is less severe in percentage terms but still significant. The 118.6 FPS at 1080p falls to 86.4 FPS at 4K, a 27.2% decrease. This smaller percentage drop compared to the High preset (43.4%) suggests that at Low settings, the system is less constrained by the GPU's pixel throughput and more by other factors, likely the CPU's ability to feed the simulation.

The behavior at 4K is particularly telling for the CPU's role. At 3840x2160, the difference between the Low and Ultra presets is 36.1 FPS (86.4 vs 50.3). At 1920x1080, that same gap is much smaller at 31.4 FPS (118.6 vs 87.2). This indicates that at 4K, the GPU is the primary limiter, and reducing graphical load has a proportionally larger impact. At 1080p, the CPU's limitations in processing the flight simulation's complex world data become more apparent, capping the maximum achievable frame rate and compressing the performance gap between presets.

Settings Recommendations

The data suggests that the Medium preset offers the most balanced experience, particularly for users targeting higher refresh rates or playing at 2560x1440. At that resolution, Medium yields 97.7 FPS, which is a 27.5 FPS improvement over the High preset's 71.2 FPS. The visual fidelity difference between Medium and High in a flight simulator is often less perceptible in the air than on the ground, making this a strong trade-off for smoothness.

For 3840x2160, the choice becomes more nuanced. The High preset achieves 51.5 FPS, which is playable but not ideal for fast-paced maneuvers. The Ultra preset drops to 50.3 FPS, a marginal 1.2 FPS difference from High, suggesting that the Ultra preset's additional effects are heavily GPU-bound and not worth the negligible performance cost at this resolution. Conversely, dropping to Medium at 4K yields 68.6 FPS, a substantial 17.1 FPS uplift over High, making it the recommended choice for a solid 4K experience. The Low preset at 4K, while hitting 86.4 FPS, sacrifices too much visual detail for a flight sim where situational awareness is key.

At 1920x1080, the system is clearly capable of high refresh rates. The Low preset hits 118.6 FPS, and Medium is not far behind at 107.8 FPS. High and Ultra presets remain well above 60 FPS at 91 and 87.2 FPS respectively. For most users at 1080p, the High preset is the sweet spot, offering a significant visual upgrade over Medium for a 16.8 FPS average loss. The Ultra preset's 4.2 FPS deficit over High is minor, making it a viable choice for those who want maximum visual fidelity without a major frame rate penalty.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this pairing, and its specifications show why it handles the resolution scaling so well. With 16 GB of GDDR6 memory on a 256-bit bus, it provides 512.0 GB/s of bandwidth. This is crucial for a game like Microsoft Flight Simulator, which streams vast amounts of terrain and texture data. The 16 GB capacity ensures that even at 4K with high-resolution textures, the GPU is not spilling over into slower system memory, which would cause stutters.

The GPU's clock speeds are also a factor. The base clock of 1825 MHz and boost clock of 2250 MHz, combined with 4608 shading units, allow for substantial compute throughput. The benchmark results reflect this power, with the GPU scoring 24980 in the Passmark G3D test and 13245 in the GPU Compute test. Its percentile ranking of 87 indicates it outperforms the vast majority of GPUs in the database. When compared to its nearest rivals, it edges out the NVIDIA GeForce RTX 4070 Ti SUPER by 2.6% and the Intel Arc A550M by 0.5% in average benchmark score, showing it is a top-tier performer.

The GPU's performance impact is most evident in the 4K results. The fact that the Ultra preset only drops 1.2 FPS compared to High at 4K suggests that the GPU is being fully utilized to its limits, and the extra effects in the Ultra preset are expensive to compute. The data confirms that the RX 6800 XT is not the limiting factor at lower resolutions, but it becomes the primary constraint as pixel count increases.

Measured FPS Breakdown

At 1920x1080, the system demonstrates a wide performance envelope. The Low preset produces an average of 118.6 FPS, which is the highest measured result in the entire dataset. Medium follows at 107.8 FPS, High at 91 FPS, and Ultra at 87.2 FPS. This shows a clear progression where each step up in quality costs a measurable amount of performance, but even the most demanding preset remains well above the 60 FPS threshold.

Moving to 2560x1440, the performance hierarchy is preserved, but the frame rates compress slightly. Low averages 111.4 FPS, Medium 97.7 FPS, High 71.2 FPS, and Ultra 66.6 FPS. The gap between Medium and High is the most significant at this resolution, with a 26.5 FPS drop, indicating the High preset introduces effects that are particularly taxing on the GPU. The Ultra preset is still playable, maintaining an average above 60 FPS.

At 3840x2160, the system's limits are tested. Low averages 86.4 FPS, which is a strong result for 4K. Medium drops to 68.6 FPS, High to 51.5 FPS, and Ultra to 50.3 FPS. The data shows a steep decline from Medium to High, a 17.1 FPS loss, confirming that the High and Ultra presets are designed for GPUs with even more headroom. The difference between High and Ultra is negligible at 1.2 FPS, suggesting the Ultra preset is not efficiently scaled for this configuration at 4K.

How This Combo Ranks

In the database of tested combinations for Microsoft Flight Simulator, this pairing of the Ryzen 5 2600 and the RX 6800 XT ranks 677th out of 1795 total combinations. This places it in the 62nd percentile of all tested systems, meaning it performs better than a majority of the configurations tested for this specific game. Given the age of the CPU, this ranking is quite respectable and reflects the strength of the GPU.

The ranking suggests that while the GPU is a high-end component, the CPU is holding the system back from achieving a top-tier position. The combo's rank is likely dragged down by the Ryzen 5 2600's performance in CPU-bound scenarios, such as the complex physics and AI calculations in the simulator. A more modern CPU with higher single-thread performance would undoubtedly push this combo higher in the rankings, as the GPU clearly has the potential to deliver even higher frame rates at lower resolutions.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen+ architecture. It has a base clock of 3.40 GHz and a boost clock of 3.90 GHz. While it is a capable processor, its single-thread performance is its weakest link in this game. In the Cinebench R23 benchmark, it scores 1579 points in the single-core test and 11186 points in the multi-core test. Its average benchmark score of 19616 places it in the 77th percentile of all CPUs.

The CPU's influence is most visible in the 1080p results. The fact that the Low preset only hits 118.6 FPS, and the Ultra preset is at 87.2 FPS, indicates that the CPU is limiting the maximum frame rate. The GPU is powerful enough to render these frames, but the CPU cannot feed it data fast enough to reach higher values. This is a classic CPU bottleneck scenario. When compared to its nearest rivals, the Ryzen 5 2600 is very closely matched with the Intel Core i7-10700F, which is only 0.7% faster in average score, and the AMD Ryzen 5 7530U, which is 0.6% slower.

The 16 MB of shared L3 cache is a crucial resource for a game that streams large amounts of world data. While the CPU's memory bandwidth of 46.9 GB/s is modest by modern standards, it is sufficient for the game's demands at these settings. The data indicates that the CPU is the bottleneck at 1080p, but as the resolution increases, the GPU takes over as the primary constraint, allowing the CPU to keep up more easily. This is why the frame rate differences between presets become more pronounced at 4K, as the GPU's workload increases.
