Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the benchmark database, and this pairing of the AMD Ryzen 5 5600X with the AMD Radeon RX 7900 XT produces a distinct performance profile across resolutions and presets. The data shows a system that is capable of high frame rates at mainstream resolutions but begins to show its limits when pushed to maximum settings at 4K. This analysis breaks down the measured FPS data, the role each component plays, and how the settings presets scale to help you find the best experience.

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

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor from the Zen 3 architecture, codenamed Vermeer. It operates on the AMD Socket AM4 platform with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. While the processor has a 65 W TDP, its benchmark scores indicate strong single-thread performance, which is critical for simulation titles. The single-thread score in Cinebench R23 is 2622, and its 3DMark single-thread score is 917. These figures place the CPU in the 78th percentile against all CPUs, suggesting it handles the per-frame logic and physics calculations that flight simulators rely on effectively.

Multi-threaded performance is also solid, with a Cinebench R23 multicore score of 18578 and a 3DMark max-thread score of 5588. The Ryzen 5 5600X sits close to its nearest rivals: it trails the AMD Ryzen 5 5600GT and Intel Core i7-10700 by 0.3%, and the Intel Core i5-12490F by 0.5%, while leading the Intel Xeon 6325P by 0.7%. This means that in CPU-bound scenarios, the 5600X is effectively at parity with these alternatives, and any performance differences in the measured FPS are more likely to come from the GPU or settings than from the processor. The 32 MB of L3 cache helps maintain consistent frame pacing, and the 4,150 million transistors on a 74 mm² die at 7 nm keep latency low.

For Microsoft Flight Simulator, the CPU’s job is to simulate the world, including terrain, weather, and aircraft systems. The benchmark results suggest that the 5600X is not the bottleneck at lower resolutions, as the frame rates scale well from 1080p to 1440p. However, the processor’s performance becomes more relevant when frame rates exceed 140 FPS, which occurs at 1080p on Low settings. In those cases, the CPU’s 6 cores and high boost clock are sufficient to feed the GPU, but the data does not show any extreme CPU-bound limitations, as the FPS drops are gradual rather than sudden.

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

The AMD Radeon RX 7900 XT is a high-end graphics card based on the RDNA 3.0 architecture, with the Navi 31 chip. It features 20 GB of GDDR6 memory on a 320-bit bus, delivering a memory bandwidth of 800.0 GB/s. The GPU has a base clock of 1387 MHz, a game clock of 2025 MHz, and a boost clock of 2394 MHz. With 5376 shading units and 84 ray accelerators, the card is built for heavy rasterization and compute workloads. Its 3DMark Steel Nomad DX12 score is 5623, and it sits in the 82nd percentile against all GPUs. The PassMark G3D score of 29009 further confirms its position as a top-tier part.

The GPU’s nearest rivals are tightly clustered. The NVIDIA GeForce RTX 5080 Mobile is at 0% delta, the NVIDIA CMP 70HX is 0.3% ahead, the NVIDIA GeForce RTX 4080 Mobile is 0.6% behind, and the NVIDIA GeForce MX570 is 0.4% behind in the database’s scoring. This means the RX 7900 XT is statistically tied with these competitors in average benchmark scores, but its 20 GB VRAM capacity is a significant advantage for a game like Microsoft Flight Simulator, which loads large textures for terrain and aircraft. The VRAM allocation likely prevents texture swapping at high resolutions, allowing the card to maintain stable frame rates even at 4K.

The GPU’s role is dominant in this pairing. At 4K, the frame rates vary significantly based on settings, indicating that the RX 7900 XT is the primary driver of performance. The card’s 51.48 TFLOPS of FP32 compute and 459.6 GPixel/s pixel rate provide ample headroom for high-fidelity rendering, but the data shows that Ultra settings at 4K push the card to its limits, hitting an average of 60 FPS. The 800 GB/s bandwidth is sufficient for the game’s data streaming, but the performance gap between Low and Ultra settings highlights the GPU’s sensitivity to shadow quality, draw distance, and volumetric effects.

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

The measured FPS data reveals a clear scaling pattern across resolutions. At 1080p, the system delivers high frame rates on all presets, with Low settings reaching 176.2 FPS and High settings at 103.8 FPS. Moving to 1440p, the frame rates drop by a noticeable margin: Low falls to 139.7 FPS, High to 85.1 FPS, and Ultra to 78.1 FPS. At 4K, the drop becomes more pronounced, with Low at 106 FPS, Medium at 80.1 FPS, High at 59 FPS, and Ultra at 60 FPS.

The scaling from 1080p to 1440p is roughly a 20-25% reduction in FPS across most settings, which is consistent with a GPU-bound workload. For example, High settings drop from 103.8 FPS at 1080p to 85.1 FPS at 1440p, a 18% decrease. From 1440p to 4K, the drop is steeper: High settings fall from 85.1 FPS to 59 FPS, a 31% decrease. This indicates that the GPU is the primary limiting component as resolution increases, since the CPU’s workload does not scale with pixel count.

The data also shows an anomaly at 4K Ultra, which averages 60 FPS, slightly higher than the 4K High average of 59 FPS. This suggests that the Ultra preset may be engaging a different rendering path or that the frame rate is being capped by a vsync or refresh rate limit, though the fact pack does not specify such a cap. The overall trend is clear: the RX 7900 XT is strong enough for 1440p gaming with headroom, but 4K requires careful settings tuning to maintain playable frame rates. The GPU’s 20 GB VRAM and high bandwidth prevent it from becoming a memory bottleneck, so the FPS drops are purely due to compute and fill rate demands.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system performs best on Low settings with an average of 176.2 FPS. Medium settings produce 139.4 FPS, High settings produce 103.8 FPS, and Ultra settings produce 102 FPS. The difference between High and Ultra is minimal at this resolution, suggesting that the Ultra preset adds graphical effects that do not significantly tax the GPU at 1080p. The CPU’s single-thread performance is sufficient to keep frame rates high, as the 5600X’s boost clock of 4.60 GHz handles the game’s simulation threads without issue.

Moving to 2560x1440, Low settings average 139.7 FPS, Medium averages 111.4 FPS, High averages 85.1 FPS, and Ultra averages 78.1 FPS. The gap between Low and Ultra narrows compared to 1080p, with a 44% difference versus a 42% difference at 1080p. This resolution is the sweet spot for this combo, as even Ultra settings maintain nearly 80 FPS, which is smooth for a flight simulator. The GPU’s 800 GB/s bandwidth and 20 GB VRAM are well-utilized here, as the higher pixel count increases memory pressure but does not exceed the card’s capacity.

At 3840x2160, the performance drops significantly. Low settings average 106 FPS, Medium averages 80.1 FPS, High averages 59 FPS, and Ultra averages 60 FPS. The Ultra setting’s 60 FPS is notably lower than the 78.1 FPS at 1440p, indicating a 23% reduction. The High and Ultra presets at 4K fall below the 60 FPS threshold that many users consider the minimum for a fluid experience, with High at 59 FPS. The data shows that this GPU can handle 4K but only on Low or Medium settings if you want to stay above 80 FPS. This is a case where the GPU’s raw power is challenged by the game’s heavy draw calls and texture detail at 4K.

Settings Recommendations

Based on the measured FPS data, the optimal preset depends on your target resolution. At 1920x1080, Ultra settings are viable, with an average of 102 FPS, which is only marginally lower than the High preset’s 103.8 FPS. The difference is negligible, so using Ultra at 1080p provides the best visual fidelity without a meaningful performance cost.

For 2560x1440, the Ultra preset averages 78.1 FPS, which is still smooth for a flight simulator. High settings average 85.1 FPS, offering a 9% FPS improvement over Ultra while sacrificing some visual effects. Given that the game is simulation-focused, the extra detail from Ultra may be worth the small frame rate drop, but High is the safer choice for maintaining headroom during complex scenes with dense terrain or weather.

At 3840x2160, the situation is more constrained. High and Ultra both average around 60 FPS, with High at 59 FPS and Ultra at 60 FPS, which is borderline for a fluid experience. Medium settings average 80.1 FPS, providing a 33% improvement over Ultra while still looking significantly better than Low. For 4K, the Medium preset is the recommended choice, as it keeps the frame rate well above 60 FPS and avoids the visual downgrades of Low. Low settings at 4K average 106 FPS, but the visual quality drop is substantial, so Medium offers the best balance of performance and fidelity. The data suggests that the RX 7900 XT is capable of 4K, but only with settings tuned down from the maximum preset.
