Microsoft Flight Simulator

Resolution Scaling

The measured performance data for Microsoft Flight Simulator with the AMD Ryzen 7 5700X and AMD Radeon RX 6600 reveals a pronounced resolution sensitivity that points directly at the GPU as the primary limiting component. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 54.9 FPS to 41.0 FPS, a reduction of roughly 25%. Scaling further to 3840x2160 at the same High preset yields 33.4 FPS, meaning the 4K result sits about 39% below the 1080p figure. This pattern is consistent across all quality presets, confirming that pixel throughput is the bottleneck rather than CPU-bound simulation logic.

At Low settings, the scaling curve is even steeper in absolute terms. The 1080p Low result of 92.6 FPS falls to 73.8 FPS at 1440p, then to 53.7 FPS at 4K. The 4K Low figure represents a 42% loss compared to 1080p Low. This large delta at the lowest preset is particularly telling: even when the visual workload is minimized, the RX 6600 cannot maintain frame rates as resolution climbs, which indicates that raw fill rate and memory bandwidth are being saturated. The GPU’s 224.0 GB/s memory bandwidth and 128-bit bus width are modest for 4K workloads, and the data reflects that constraint.

Medium settings show a similar trajectory: 74.2 FPS at 1080p, 56.0 FPS at 1440p, and 40.3 FPS at 4K. The step from 1440p to 4K at Medium costs roughly 28% performance, while the step from 1080p to 1440p costs about 24%. This near-linear scaling in percentage terms suggests the GPU is consistently the limiting factor across all three resolutions. Ultra settings, meanwhile, start at 52.7 FPS at 1080p, drop to 43.4 FPS at 1440p, and reach 30.4 FPS at 4K. The 4K Ultra result is the only sub-30 FPS figure in the dataset, underscoring that this combination is not viable for maximum quality at 4K.

The fact that 1080p Low achieves 92.6 FPS while 1080p Ultra achieves 52.7 FPS — a 43% gap — further supports the GPU-bound interpretation. The CPU, with its 8 cores and 16 threads based on Zen 3 architecture, has ample headroom for flight simulation’s single-threaded and lightly threaded workloads. The data shows no evidence of CPU saturation: the frame rate deltas between resolutions are far larger than any quality preset differences would cause if the CPU were the constraint.

CPU Role

The AMD Ryzen 7 5700X brings 8 cores and 16 threads to this pairing, running at a base clock of 3.40 GHz and a boost clock of 4.60 GHz. Its benchmark results show strong multithreaded capability — Cinebench R23 multi-core scores 22620, and 3DMark 16-thread scores 6858 — but Microsoft Flight Simulator’s frame rate data indicates that this processing power is not the limiting factor in this configuration. The CPU’s single-thread performance, measured at 3DMark single-thread score of 921 and Cinebench R23 single-core score of 3193, is adequate for the game’s simulation-heavy workload, yet the frame rates scale primarily with resolution and quality settings rather than CPU frequency or core count.

Comparing to nearest rivals, the 5700X sits within a tight band. Its average benchmark score of 26214 is 0.1% above the Intel Core i9-11900KF (26196), 0.2% above the AMD Ryzen 5 5500GT (26161), and 0.2% below both the AMD Ryzen 7 PRO 6850U (26262) and AMD Ryzen 5 7600X (26272). This clustering means that swapping the CPU for any of these alternatives would yield negligible frame rate changes in this game, given the GPU-bound nature of the measured results. The percentile rank of 83 versus all CPUs confirms the 5700X is a solid mid-to-high tier processor, but its role here is to feed frames to the GPU without becoming a bottleneck — which the data confirms it does.

The CPU’s 32 MB shared L3 cache and DDR4 memory support at 51.2 GB/s bandwidth are sufficient for flight simulation’s terrain and object streaming demands. No measured frame rate data suggests that cache misses or memory latency are causing stutter or drops. The 65 W TDP also indicates thermal headroom is not a concern for sustained performance. In essence, the Ryzen 7 5700X performs its role competently, but the benchmark results in this game are dictated almost entirely by the GPU’s capabilities.

GPU Role

The AMD Radeon RX 6600 is the clear performance ceiling in this combination. With 8 GB of GDDR6 memory on a 128-bit bus delivering 224.0 GB/s bandwidth, and a boost clock of 2491 MHz alongside a game clock of 2044 MHz, the GPU’s specifications align with the observed frame rate behavior. The 4K Ultra result of 30.4 FPS and 4K High result of 33.4 FPS both indicate that the RX 6600’s 8 GB frame buffer and bandwidth are stretched at high pixel counts. The GPU’s 1792 shading units and 64 ROPs provide a pixel rate of 159.4 GPixel/s, which is adequate for 1080p and playable for 1440p, but insufficient for smooth 4K gameplay in a demanding title like Microsoft Flight Simulator.

The GPU’s benchmark profile places it at the 69th percentile versus all GPUs, with an average benchmark score of 25235. Its nearest rivals show how tightly grouped this segment is: the AMD Radeon 890M matches at 25246 (0% delta), the AMD Radeon RX 580 2048SP scores 25287 (-0.2% delta), the AMD Radeon RX 6700M scores 25180 (0.2% delta), and the NVIDIA GeForce RTX 3060 Ti scores 25120 (0.5% delta). These deltas are all within 0.5%, meaning the RX 6600’s performance is essentially interchangeable with these alternatives in synthetic benchmarks. The measured game data, however, shows that Microsoft Flight Simulator’s specific demands — likely heavy texture streaming and draw call handling — align with the GPU’s mid-range positioning.

The fact that 1080p Low achieves 92.6 FPS while 4K Ultra achieves 30.4 FPS — a 67% drop — quantifies the GPU’s resolution scaling limits. The RX 6600 is best suited for 1080p gaming, where it delivers between 52.7 FPS (Ultra) and 92.6 FPS (Low), and it can handle 1440p with adjusted settings, where the range is 43.4 FPS (Ultra) to 73.8 FPS (Low). At 4K, only the Low preset breaks 50 FPS, and even that is marginal. The GPU’s VRAM capacity of 8 GB is not the sole issue — bandwidth and fill rate are the more likely constraints, given that Low settings at 4K still only manage 53.7 FPS.

How This Combo Ranks

This specific CPU-GPU pairing ranks 1443 out of 1795 tested combinations in Microsoft Flight Simulator, placing it in the lower-middle tier of the benchmark database. The rank of 1443 out of 1795 means roughly 80% of tested combos perform better in this game, which is consistent with the RX 6600 being a 1080p-focused GPU paired with a capable but not top-tier CPU. The Ryzen 7 5700X’s strong CPU benchmarks do not boost the combo’s rank because the game is GPU-limited; the bottleneck is evident from the resolution scaling analysis.

The combo’s rank relative to the CPU’s 83rd percentile and GPU’s 69th percentile suggests that the pairing is not optimized for this game’s demands. A stronger GPU would shift the rank substantially upward, while a stronger CPU would yield minimal gains because the frame rates are already GPU-bound. The data shows that the combo’s best performance — 92.6 FPS at 1080p Low — is respectable for esports-style play but not competitive for high-refresh-rate 1440p or 4K gaming. The rank reflects this reality: it is a functional mid-range setup that delivers playable frame rates at 1080p and 1440p with quality adjustments, but it does not excel in any resolution tier.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear hierarchy: Low settings produce 92.6 FPS average, Medium produces 74.2 FPS, High produces 54.9 FPS, and Ultra produces 52.7 FPS. The gap between High and Ultra is small (4%) compared to the gap between Medium and High (26%), suggesting diminishing returns from quality settings beyond Medium. The 1080p Low result is the only figure above 90 FPS in the entire dataset, making it the standout performance point for this combo.

At 2560x1440, the averages are 73.8 FPS (Low), 56.0 FPS (Medium), 41.0 FPS (High), and 43.4 FPS (Ultra). Notably, the Ultra preset at 1440p (43.4 FPS) outperforms the High preset (41.0 FPS), which is an anomaly in the data — likely a measurement variance or a specific scene difference in the benchmark run. The 1440p Low result of 73.8 FPS remains playable, but High and Ultra dip below 45 FPS, which is marginal for a flight simulator where smooth camera panning matters.

At 3840x2160, all results are below 60 FPS: Low yields 53.7 FPS, Medium yields 40.3 FPS, High yields 33.4 FPS, and Ultra yields 30.4 FPS. The 4K Low result is the only 4K figure that approaches playability, and even it falls short of a stable 60 FPS target. The 4K Ultra result of 30.4 FPS is the lowest in the dataset, confirming that this resolution and quality combination is not recommended for this hardware.

Across all resolutions, the Low preset consistently delivers the highest frame rates, with a 43% improvement over Ultra at 1080p (92.6 vs 52.7 FPS) and a 77% improvement at 4K (53.7 vs 30.4 FPS). The data suggests that Low settings are the most efficient use of the GPU’s resources, while Ultra settings provide marginal visual gains at significant performance costs.

Settings Recommendations

The measured data points to a clear recommendation: for the best balance of visual fidelity and frame rate, 1920x1080 with High settings delivers 54.9 FPS, which is playable for a flight simulator where precision matters more than competitive frame rates. If smoothness is the priority, dropping to Medium at 1080p yields 74.2 FPS — a 35% improvement over High with a modest visual trade-off. The Low preset at 1080p (92.6 FPS) is only advisable for users who prioritize maximum smoothness over terrain detail, as flight simulators benefit from higher quality textures for navigation.

At 2560x1440, the data recommends Medium settings (56.0 FPS) as the sweet spot, since Low (73.8 FPS) sacrifices too much visual quality and High (41.0 FPS) dips below the 45 FPS comfort threshold. The 1440p Ultra result of 43.4 FPS is technically higher than High, but the anomaly suggests inconsistent performance, so Medium is the safer choice. For 4K, the only viable option is Low settings (53.7 FPS), and even that is marginal — users with 4K displays should consider reducing resolution to 1440p for a better experience.

The overall best experience per the measured rows is 1080p Medium at 74.2 FPS, which offers a strong frame rate while retaining enough visual detail for practical flight simulation. Users with higher refresh rate monitors can opt for 1080p Low to approach 93 FPS, but the visual compromise is significant. The Ultra preset is not recommended at any resolution, as it provides less than 10% improvement over High at 1080p (52.7 vs 54.9 FPS) while costing more than 4% performance at 1440p (43.4 vs 41.0 FPS) — the data shows Ultra is not worth the frame rate penalty in this game.
