# Microsoft Flight Simulator with AMD Ryzen 9 7900X + AMD Radeon RX 6600 XT

This combination of the 12-core AMD Ryzen 9 7900X and the 8 GB AMD Radeon RX 6600 XT produces a playable but resolution-sensitive experience in Microsoft Flight Simulator. The measured data shows a clear pattern: at 1080p the system delivers smooth frame rates across all settings, while 4K Ultra pushes the GPU to its limits, dropping to 33 FPS average. The CPU's strong single-thread performance (2,016 in Cinebench R23 single-core) helps maintain decent minimums at lower resolutions, but the GPU becomes the primary constraint as pixel count rises. This analysis walks through the measured FPS data, settings behavior, and component roles to clarify what this combo can and cannot do in this flight simulator.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a classic GPU-bound scaling pattern. At Low settings, the average frame rate falls from 101 FPS at 1920x1080 to 81 FPS at 2560x1440, then to 60 FPS at 3840x2160. That is a 40% reduction from 1080p to 4K, which is substantial but expected for a flight sim with heavy draw distances. The step from 1440p to 4K costs 21 FPS, while the step from 1080p to 1440p costs 20 FPS, so the scaling is nearly linear in this range.

At Medium settings, the pattern shifts slightly. The 1920x1080 result is 78 FPS, dropping to 63 FPS at 2560x1440 and 47 FPS at 3840x2160. The percentage loss from 1080p to 4K is roughly 40% again, matching the Low setting behavior. However, the 1440p to 4K step (16 FPS loss) is smaller than the 1080p to 1440p step (15 FPS loss), suggesting the GPU's memory bandwidth of 256.0 GB/s begins to matter more at higher resolutions.

High settings show a slightly different story. The 1080p average is 59 FPS, which drops to 47 FPS at 1440p and 35 FPS at 4K. The 1440p to 4K loss is 12 FPS, while the 1080p to 1440p loss is also 12 FPS. This consistency indicates that at High settings, the GPU is the limiting factor at every resolution above 1080p, with the 8 GB VRAM and 128-bit memory bus constraining performance.

Ultra settings produce the steepest curve. At 1080p the average is 56 FPS, falling to 45 FPS at 1440p and 33 FPS at 4K. The 4K Ultra result of 33 FPS is the lowest measured value across the entire dataset, confirming that this resolution/settings combination exceeds what the RX 6600 XT can handle smoothly. The data suggests the limiting component at 4K is clearly the GPU, as the CPU's 12 cores and 24 threads provide ample headroom for the simulator's simulation logic, while the GPU's 10.60 TFLOPS FP32 throughput and 8 GB memory are stretched thin.

Settings Recommendations

The measured rows provide a clear hierarchy for choosing settings based on target resolution. At 1920x1080, Medium settings deliver 78 FPS average with a minimum of 66 FPS and maximum of 90 FPS, which is the best balance of smoothness and visual fidelity in the dataset. Low settings at 1080p reach 101 FPS, but the visual quality loss is significant for a simulator where cockpit readability and terrain detail matter. High settings at 1080p drop to 59 FPS, which is playable but leaves little margin for complex scenes or dense urban areas.

At 2560x1440, Medium settings produce 63 FPS average with a 54 FPS minimum and 73 FPS maximum. This is the recommended preset for this resolution, as it stays above 60 FPS on average while maintaining acceptable visual detail. High settings at 1440p fall to 47 FPS, which is borderline for a flight simulator where smooth panning is essential. Low settings at 1440p reach 81 FPS, but users who want the medium preset's extra detail will find the 63 FPS average more than adequate.

For 3840x2160, the situation is more constrained. Low settings achieve 60 FPS average, which is exactly at the threshold for smooth gameplay. Medium settings at 4K drop to 47 FPS with a 40 FPS minimum, which is playable but noticeable stutter may occur during rapid camera movements. High settings at 4K yield 35 FPS, and Ultra settings produce 33 FPS, both of which fall below the 40 FPS minimum seen in the Medium preset. The data indicates that 4K users should stick to Low or Medium settings, with Medium being the better choice for visual quality at 47 FPS average.

CPU Role

The AMD Ryzen 9 7900X brings 12 cores and 24 threads to this combination, with a base clock of 4.70 GHz and boost clock of 5.60 GHz. Its benchmark results show a single-thread score of 2,016.5 in Cinebench R23 and 1,093 in 3DMark single-thread, which are relevant for a flight simulator that relies heavily on main-thread simulation logic. The multi-thread scores are strong as well, with 29,300 in Cinebench R23 multi-core and 12,536 in 3DMark max threads, but Microsoft Flight Simulator typically uses fewer threads for the core simulation loop.

The CPU's percentile rank of 91 among all tested CPUs indicates it is a high-performance part, but the measured FPS data shows that the GPU becomes the bottleneck at higher resolutions. At 1080p Low, the 101 FPS result suggests the CPU is capable of feeding the GPU well above 100 FPS in less demanding scenes. Even at 1080p Ultra, the 56 FPS average indicates the CPU can maintain reasonable frame pacing when the GPU is not overwhelmed.

Compared to its nearest rivals in the CPU benchmark database, the 7900X's average benchmark score of 53,288 is within 0.6% of the Intel Xeon 634 (52,974) and 0.2% of the AMD EPYC 7313P (53,206). The Intel Core i7-14700F scores 53,620, which is 0.6% higher, while the Intel Xeon Phi 7290 scores 53,469, 0.3% higher. These differences are negligible for gaming, meaning the 7900X's CPU performance is not a differentiator in this game's FPS results.

Q: Is this combo ranked high among tested combinations?

A: The combo ranks 2,571 out of 3,714 tested combinations, placing it in the lower third of the database. This reflects the GPU's mid-range positioning, as the CPU is a high-end part but the RX 6600 XT limits overall performance in this game.

GPU Role

The AMD Radeon RX 6600 XT is built on the Navi 23 chip with RDNA 2.0 architecture, using a 7 nm process from TSMC. It features 8 GB of GDDR6 memory on a 128-bit bus, providing 256.0 GB/s of bandwidth. The boost clock is 2,589 MHz, with a game clock of 2,359 MHz. Its compute capabilities include 2,048 shading units, 128 texture mapping units, and 64 render output units, delivering 10.60 TFLOPS of FP32 performance and a pixel rate of 165.7 GPixel/s.

The GPU's 8 GB VRAM is a critical factor in this game. The measured FPS at 4K Ultra is 33 FPS, which is only 3 FPS higher than the 4K High result of 35 FPS. This small difference suggests that the GPU is not only limited by raw compute but also by memory capacity and bandwidth. The 256.0 GB/s bandwidth is moderate for a card in this class, and Microsoft Flight Simulator's large texture sets and draw distances can exceed 8 GB at high resolutions.

The GPU's percentile rank of 70 among all GPUs places it in the upper-mid range, but its nearest rivals include the NVIDIA GeForce RTX 2080 SUPER, which scores 24,170 versus the RX 6600 XT's 24,442 — a 1.1% difference. This means the RX 6600 XT performs similarly to a much older high-end card in synthetic benchmarks. In this game, however, the measured FPS shows that the GPU is the primary constraint at 1440p and 4K, particularly at High and Ultra settings.

Measured FPS Breakdown

The dataset provides average FPS for all four settings at three resolutions, with minimum and maximum values for Medium settings. At 1920x1080, the Low preset averages 101 FPS, Medium averages 78 FPS (minimum 66, maximum 90), High averages 59 FPS, and Ultra averages 56 FPS. The spread from Low to Ultra is 45 FPS, which is the largest range across all resolutions, indicating that at 1080p the GPU has enough headroom to benefit from lower settings.

At 2560x1440, Low averages 81 FPS, Medium averages 63 FPS (minimum 54, maximum 73), High averages 47 FPS, and Ultra averages 45 FPS. The spread from Low to Ultra is 36 FPS, slightly smaller than at 1080p. The Medium preset's minimum of 54 FPS suggests that even at 1440p, there can be dips below 60 FPS during complex scenes.

At 3840x2160, Low averages 60 FPS, Medium averages 47 FPS (minimum 40, maximum 54), High averages 35 FPS, and Ultra averages 33 FPS. The spread from Low to Ultra is 27 FPS, the smallest of the three resolutions. This tightening indicates that at 4K, the GPU is operating near its limits even at Low settings, and the performance gains from reducing settings diminish as resolution increases.

The Medium settings data is the only set with minimum and maximum values. At 1080p, the 66 to 90 FPS range shows a 24 FPS variation, which is significant but manageable. At 1440p, the range narrows to 54 to 73 FPS, a 19 FPS variation. At 4K, the range is 40 to 54 FPS, a 14 FPS variation. The narrowing range at higher resolutions suggests that the GPU's frame time consistency improves when it is more heavily loaded, but the absolute performance drops below the 60 FPS threshold.

How This Combo Ranks

This combination of the Ryzen 9 7900X and RX 6600 XT ranks 2,571 out of 3,714 tested combos in Microsoft Flight Simulator, placing it in the 31st percentile of the database. This ranking is primarily driven by the GPU's mid-range positioning, as the CPU's percentile rank of 91 is far higher than the GPU's percentile rank of 70. The data shows that even with a high-end 12-core CPU, the RX 6600 XT limits the system to average FPS values that are below what many other GPU combinations achieve.

The ranking implies that in the broader context of tested hardware, this combo is better suited for 1080p and 1440p gaming with Medium settings, rather than pushing for high refresh rates or 4K Ultra. The CPU's strong benchmark scores (29,300 in Cinebench R23 multi-core and 2,016.5 single-core) suggest that if paired with a more powerful GPU, this system could achieve significantly higher FPS. However, as measured, the combo's performance is constrained by the GPU's 8 GB memory and 256.0 GB/s bandwidth, which are insufficient for this game's most demanding settings at high resolutions.

The rank of 2,571 out of 3,714 also indicates that roughly 69% of tested combinations outperform this one in Microsoft Flight Simulator. This is consistent with the GPU's nearest rival comparisons, where the RX 6600 XT scores only slightly above or below cards from different generations. The combination's strength lies in its CPU, but that strength does not translate into higher FPS in this game because the simulator is heavily GPU-bound at the resolutions and settings where the GPU struggles.
