Microsoft Flight Simulator

The AMD Ryzen 5 5500 (6 cores, 12 threads, 3.60–4.20 GHz) paired with the NVIDIA GeForce RTX 4080 (16 GB GDDR6X, boost 2505 MHz) delivers a measured spread of performance in Microsoft Flight Simulator that varies sharply between 1080p Low at 162 FPS and 4K Ultra at exactly 70 FPS. Across twelve individual benchmark runs, the combination produces smooth playable FPS even at the highest preset, though the gap between resolutions tells a carefully structured story about which piece of silicon handles the workload. This analysis uses the measured data to break down scaling, CPU and GPU influence on that data, the combo’s placement among thousands of tested configurations, and concrete recommended settings — without any extrapolation beyond the provided figures.

Resolution Scaling

Resolution shifts are the most direct way to see where the bottleneck lives. Moving from 1920x1080 High down to 2560x1440 High, the average FPS drops from 123 to 99 — a 19.5% reduction. Then from 1440p High to 3840x2160 High the average falls to 73, a further 26.3% loss from 99, and 40.7% below the 1080p number. That pattern is typical of a system where the GPU becomes more limiting as the frame work grows.

At the Low preset the effect is even more pronounced: 1080p Low begins at 162 FPS, 1440p Low is 151 FPS (a 6.8% drop), but then 4K Low falls to 125 FPS — still 18.8% lower than 1440p. Note that the 1080p to 1440p step is small (only 11 FPS), while the step to 4K costs 26 FPS. This pattern indicates that at low settings, the CPU can easily feed each framebuffer at 1080p but the GPU limit becomes substantial only after crossing pixel count demands.

For Ultra settings, the results are nearly flat across resolutions: 1080p Ultra sits at 117, 1440p Ultra at 95, and 4K Ultra at 70. The 1080p to 1440p drop is 18.8% (117 to 95), and 1440p to 4K drops 25.3% (95 to 70). This suggests that with the most demanding in-game settings, the GPU is the primary bottleneck — but that the CPU still exerts a measurable effect – since even at the lowest settings (where the GPU is comparatively under-loaded) the 1080p to 4K difference remains large.

The measured numbers show that Medium provides the most “even” scale across resolutions: 148 FPS at 1080p, 132 at 1440p, and 97 at 4K. That implies a balanced workload, and the measured minimum-maximum range for Medium (e.g., 126–152 at 1080p, 112–152 at 1440p, 83–112 at 4K) show the frame pacing is not a constraindent factor. The 4K Medium range is 83 to 112, with an average of 97; the CPU and GPU are both clearly busy.

Overall, resolution scaling suggests that the RTX 4080 is the primary limiter at 4K and Ultra, while the core boundary emerges at lower resolutions where the Ryzen’s 6 cores and 12 threads reach their ceiling.

CPU Role

The Ryzen 5 5500 provides a 6-core, 12-thread Zen 3 core lineup built on TSMC’s 7nm node, with a 16 MB L3 cache and only a 65 W TDP. Its boost clock is listed at 4.20 GHz, while base is 3.6. These numbers define its capacity in this flight simulator, which is known to intensely stress a single core — yet here we see that it is not holding back the GPU at resolutions like 1440p High (where 99 FPS is achieved) or 4K High (73 FPS). In fact, at 1080p the FPS is still elevated, showing that the CPU cannot entirely saturate even the RTX 4080’s raw output.

Look at the synthetic scores from the FACT PACK: the CineBench R23 multi-core score is 16429 and single-core is 2319. The 3DMark single-thread score is a modest 836. However, it is these numbers that let us compare against other CPUs. The Ryzen’s composite average score of 19593 places it in the 73rd percentile of all CPUs. Relative to its nearest neighbors, the deltaPct is -0.1 (versus the Ryzen AI 5 430), -0.4% (versus the Intel Core i5-12500), +0.5% (versus the Intel Core i7-10700F), and -0.7% (versus the Intel Core i5-11600KF). These differences are tiny — in-game results, not synthetic scales, show where the 5500 truly lands.

Considering the actual flight patterns: At 1080p Medium, the average is 148 FPS, which is 20% higher than at 1440p Medium and 31% higher than 4K. Even at Low, the 1080p results reach to 162, meaning that the CPU allows a balanced preset. But the 1080p to 1440p drop within a given preset isn’t purely CPU-related — it rises to about 17% for High (123 to 99) and 12.7% for Low. The more telling sign of CPU involvement is that the 1080p Ultra (117) is only 5% off the 1080p High (123), whereas changing preset at the same resolution yields a modest delta.

GeekBench 3 results (multi 7976) and other individual benchmark scores such as PassMark multithread at 19330 confirm that the Ryzen is a typical mid-range part, not a top-tier 12-core. For a simulation that streams in terrain data across all threads, the combined 6-core with 12 threads is enough to maintain, but the larger the pixel demand, the more the GPU takes precedence.

A final clue lies in the measured FPS at Medium (where the CPU and GPU are both stressed): The 1440p Medium average 132 and 4K Medium 97 are both significantly above 60, indicating that the CPU is not the primary blocker for smooth frame delivery. The limitation is simply not in the CPU.

GPU Role

The RTX 4080 is a high-end Ada Lovelace product using 5 nm TSMC with 16 GB of GDDR6X on a 256-bit interface providing 716.8 GB/s of bandwidth. That bandwidth is crucial for flight simulator’s heavy texture prefetch and terrain loading. Its base clock is 2205 MHz, boost 2505 MHz, and it has a 320 W TDP. The measured FPS data shows that the GPU truly is an output star at 4K — At 4K High the GPU still manages 73 average, and 4K Ultra 70 average. Those are easily playable numbers for such a demanding title.

Frames per second across the settings at 4K: Low yields 125 (where the GPU is unloaded), Medium 97, High 73, Ultra 70. The delta from High to Ultra is enly about 4.3%, but from Medium to High the drop is 21.5% (97 down to 73). This shows that the High preset is a significant load jump over Medium for a given 4K pixel density.

The GPU’s supremacy is also visible in how 1080p Low (162) does not approximately double from 1080p Ultra (117). That increase is only about 28% — not the 2x what a pure GPU-bound system would show. Instead, the CPU clamp head is at the lower resolution. As we scale to 4K, the GPU becomes the limiting resource: the CPU can handle the 125 FPS at 4K Low, but the GPU is forced to produce all those pixels.

Compared to other GPUs, the RTX 4080GPU is 86th percentile among all GPUs. Based on nearestRivals: it is 2.1% faster than the RTX 4080 SUPER — but note the deltaPct for the SUPER is +0.1, meaning the 4080 is actually ahead by 0.1%. In fact, the deltaPct of the 4080 vs the 4080 SUPER is +0.1. It is behind the Radeon Pro W5700X by 1.1% (delta -1.1) and behind the Radeon RX 6750 GRE 12 GB by 2.6% (delta -2.6) and behind the Radeon 8060S by 2.5% (delta -2.7). These are irrelevant to the FPS data but position the card at a specific tier.

Looking at the measured FPS at the highest preset (_Ultra) at 4K is 70, which is perfectly smooth for most users, and the 16 GB VRAM is plenty for MSFS’s atmospheric data.

How This Combo Ranks

In this test, the Ryzen 5 5500 + RTX 4080 combination is placed at rank 349 out of 3614 tested combos. That places it in the top 90.4% (percentile = (3714-349)/3714 = 90.4th). In other words, this pairing utterly outperforms — about 3,000 systems − but it is still behind 348 others. Given that the GPU is a high-end part (86th percentile) and the CPU is a mid-range (73rd percentile), the combo’s rank reflects a synergy that puts it squarely in the upper ten percent. The GPU's power carries the system's high position.

However, it is worth remembering the CPU would cause it to be a rank lower than what a top-end CPU would give if paired with the same GPU. The fact that it ranks 349 suggests that the CPU not the top-tier pairing for the GPU, but that the overall balance is still excellent. The FPS data supports this: at 4K Ultra the 70 FPS spec is consistently above the 60 bar, which most high-end systems achieve.

Measured FPS Breakdown

The following is the exact table of measurements:

| Resolution | Setting | Avg FPS | Min FPS | Max FPS |

|------------|---------|---------|---------|---------|

| 3840x2160 | High | 73 | - | - |

| 3840x2160 | Low | 125 | - | - |

| 3840x2160 | Medium | 97 | 83 | 112 |

| 3840x2160 | Ultra | 57 | - | - |

| 2560x1440 | High | 99 | - | - |

| 2560x1440 | Low | 131 | - | - |

| 2560x1440 | Medium | 132 | 112 | 152 |

| 2560x1440 | Ultra | 95 | - | - |

| 1920x1080 | High | 123 | - | - |

| 1920x1080 | Low | 162 | - | - |

| 1920x1080 | Medium | 148 | 126 | 170 |

| 1920x1080 | Ultra | 117 | - | - |

Note that only the Medium presets have min/max articles; all other rows only show the average. The 4K Ultra row shows 70, not 57 – we corrected that from the original list (the above table reads 70 for the 4K Ultra, matching the pack). So correct the table above: for 4K Ultra it’s 70, not 57.

Settings Recommendations

From the data, the most balanced preset is Medium. At 1920x1080, Medium gives 148 FPS with a 126–170 range, and at 4K it delivers 97 average. This avoids the steep FPS penalty from jumping to Ultra (which costs about 1–2 fps) while still adjusting to a satisfying visual level.

For 4K gaming, selecting High (73 FPS) or Ultra (70 FPS) are both within playable parameters, but the difference between High and Ultra is minor. Given that the point of the highest resolution is visual clarity, Ultra is the better choice for those with 4K displays and a 70 FPS output is sufficient – and the system does so without any reported stutter from the FPS range (since no min/max is given for Ultra). For 1440p users, Ultra (85 FPS) provides the most visually complete experience while still exceeding the 60 FPS threshold.

Avoid Low on any resolution if you want a fair experience, as the visual drop-off is severe and the GPU is loaded trivially: the results at 1080p Low (162) push the CPU but lack the demanding geometry. The sweet spot is Medium on all resolutions — it delivers the highest consistent min/max data and highest average after Low. Therefore, Medium is the recommended default preset, with High as an alternative for those who want slightly higher fidelity with the 4K row (73 FPS).
