# Microsoft Flight Simulator: AMD Ryzen 7 7700X + NVIDIA GeForce RTX 3080

This combination of AMD's Zen 4-based Ryzen 7 7700X and NVIDIA's Ampere-generation RTX 3080 delivers a playable experience in Microsoft Flight Simulator, though the data reveals a system that is consistently GPU-limited at higher resolutions and increasingly CPU-bound as resolution drops. The measured frame rates across all twelve tested configurations show a predictable scaling pattern, with the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth proving sufficient for the simulator's demands at 1440p and 4K, while the 8-core, 16-thread Ryzen 7 7700X with its 5.40 GHz boost clock becomes the limiting factor at 1080p. This combo ranks 1036 out of 3714 tested combinations, placing it in the upper third of all systems evaluated for this title.

Resolution Scaling

The frame rate progression from 1080p to 4K tells a clear story about where this system's bottleneck shifts. At Low settings, the transition from 1920x1080 to 2560x1440 sees average FPS drop from 158 to 127, a reduction of 31 FPS or roughly 20%. Moving further to 3840x2160 at Low, the average falls to 94 FPS, another 33 FPS decline. This linear degradation suggests that at Low presets, the GPU is the primary constraint even at 1080p, as the frame rates remain high enough to keep the CPU's 16 threads from becoming saturated.

The Medium preset shows a similar pattern: 123 FPS at 1080p, 99 FPS at 1440p, and 73 FPS at 4K. The gap between 1080p and 1440p (24 FPS) is slightly smaller than the 1440p-to-4K drop (26 FPS), indicating that the RTX 3080's pixel throughput begins to strain more severely as resolution climbs. At High settings, the scaling becomes more pronounced: 92 FPS at 1080p, 74 FPS at 1440p, and 55 FPS at 4K. Here, the 1080p-to-1440p loss is 18 FPS, while the 1440p-to-4K loss is 19 FPS, showing a consistent degradation pattern.

Ultra settings produce the lowest frame rates and the most dramatic scaling: 88 FPS at 1080p, 71 FPS at 1440p, and 52 FPS at 4K. The 1080p-to-1440p drop of 17 FPS is nearly identical to the 1440p-to-4K drop of 19 FPS, suggesting that at Ultra, the GPU is the dominant limiting component across all resolutions. However, the fact that 1080p Ultra (88 FPS) and 4K High (55 FPS) differ by 33 FPS indicates that the RTX 3080's 8704 shading units are being pushed to their limits by the simulator's rendering workload at higher preset levels.

Notably, the gap between Low and Ultra settings widens dramatically as resolution decreases. At 1080p, the spread from Low (158 FPS) to Ultra (88 FPS) is 70 FPS, or 44%. At 1440p, that spread narrows to 56 FPS (127 to 71), and at 4K it contracts to 42 FPS (94 to 52). This compression at higher resolutions confirms that pixel fill rate becomes the overriding factor, while at 1080p, the CPU's ability to feed the GPU with draw calls and simulation data becomes more relevant.

GPU Role

The NVIDIA GeForce RTX 3080, built on the GA102 chip with 28,300 million transistors on an 8 nm Samsung process, provides the graphical horsepower for this configuration. Its 10 GB of GDDR6X memory operates at 19 Gbps effective across a 320-bit bus, yielding 760.3 GB/s of memory bandwidth. This bandwidth proves critical in Microsoft Flight Simulator, which streams vast terrain and scenery data; the measured frame times at Medium settings (62 FPS minimum at 4K) suggest the memory subsystem can keep up with the simulator's data demands without causing stutter.

The GPU's boost clock of 1710 MHz, combined with 68 RT cores and 272 tensor cores, supports the simulation's rendering features. The FP32 compute throughput of 29.77 TFLOPS helps drive the complex shading workloads, while the texture rate of 465.1 GTexel/s and pixel rate of 164.2 GPixel/s determine how quickly the simulator can fill the screen with detailed cockpit instruments and ground textures. At 4K Ultra, the 52 FPS average indicates the GPU is operating near its practical limit for this title.

The RTX 3080's 96 ROPs handle the final pixel output, and the measured data shows that at 4K High (55 FPS) and 4K Ultra (52 FPS), the GPU is delivering close to what the architecture can manage. The PassMark G3D score of 25086 places this GPU at the 68th percentile among all tested graphics cards, with its nearest rivals including the NVIDIA P106-100 (0.3% delta), AMD Radeon Pro Vega 16 (0.3% delta), and AMD Radeon RX 6600M (0.4% delta). While these rivals are lower-tier parts, the delta values are small, suggesting the RTX 3080 sits in a dense performance cluster.

At 1080p, the GPU's role diminishes relative to the CPU. The jump from 158 FPS at Low to 123 FPS at Medium (a 35 FPS drop) is smaller than the drop from Medium to High (31 FPS), indicating that the GPU's fixed-function units handle the additional settings complexity efficiently. The 1080p Ultra result of 88 FPS shows that even at maximum settings, the RTX 3080 can maintain a playable frame rate, though the 10 GB VRAM capacity is a consideration — the simulator's high-resolution texture packs can approach this limit, but the measured 4K performance suggests the memory allocation is adequate.

Settings Recommendations

The measured FPS rows provide clear guidance for optimizing the experience. At 4K, the Medium preset delivers 73 FPS average with a minimum of 62 FPS and maximum of 84 FPS, which is the smoothest playable configuration at this resolution. The High preset drops to 55 FPS and Ultra to 52 FPS, both of which are technically playable but may exhibit noticeable frame pacing issues in dense scenarios. Low at 4K achieves 94 FPS but sacrifices too much visual fidelity for a simulator where terrain and aircraft detail matter.

At 1440p, the Medium preset offers the best balance: 99 FPS average with a minimum of 84 FPS and maximum of 114 FPS. This configuration provides a comfortable margin above 60 FPS for demanding flight scenarios. The High preset at 74 FPS is also viable, but the 25 FPS difference between Medium and High represents a significant visual quality trade-off that may not be worth the frame rate loss for all users. The Ultra preset at 71 FPS is nearly identical to High, suggesting diminishing returns at the top settings.

For 1080p users, the Medium preset stands out: 123 FPS average with a minimum of 104 FPS and maximum of 141 FPS. This is well above the 60 FPS threshold and provides headroom for sudden scenery loading. The High preset at 92 FPS is also excellent, and the Ultra preset at 88 FPS remains playable. Given that the gap between High and Ultra at 1080p is only 4 FPS, users prioritizing visual quality can choose Ultra without a major frame rate penalty.

The data suggests that Medium is the sweet spot across all resolutions for this combo. At 4K, it is the only preset that maintains an average above 70 FPS; at 1440p, it provides the most consistent frame pacing; and at 1080p, it delivers the highest minimum frame rate (104 FPS) among the playable settings. Users with high-refresh monitors at 1080p may prefer Low (158 FPS), but the visual compromise is substantial for a game where immersion depends on detailed scenery.

Measured FPS Breakdown

At 1920x1080, the measured results span a wide range. Low settings produce 158 FPS average, Medium reaches 123 FPS with a minimum of 104 and maximum of 141, High delivers 92 FPS, and Ultra yields 88 FPS. The progression from Low to Medium (35 FPS drop) is larger than Medium to High (31 FPS) or High to Ultra (4 FPS), showing that the Medium preset adds significant visual work that the GPU handles well.

At 2560x1440, the frame rates compress somewhat. Low achieves 127 FPS, Medium hits 99 FPS with a minimum of 84 and maximum of 114, High reaches 74 FPS, and Ultra produces 71 FPS. The gap between Low and Medium is 28 FPS, between Medium and High is 25 FPS, and between High and Ultra is just 3 FPS. This tightening at the top end indicates that the RTX 3080's rendering pipeline becomes more uniform as resolution increases.

At 3840x2160, the results show the GPU's limits clearly. Low averages 94 FPS, Medium 73 FPS with a minimum of 62 and maximum of 84, High 55 FPS, and Ultra 52 FPS. The 4K Medium minimum of 62 FPS is notable — it suggests that the combo can maintain playable frame rates even during demanding scenes, though the 84 FPS maximum indicates variability that could cause occasional hitches. The 4K High and Ultra results (55 and 52 FPS) are close, suggesting that the Ultra preset's additional effects have minimal marginal cost at this resolution.

Comparing across resolutions, the 1080p Low result of 158 FPS versus the 4K Low result of 94 FPS represents a 40% reduction, while the 1080p Ultra (88 FPS) versus 4K Ultra (52 FPS) is a 41% reduction. This consistency indicates that the GPU's scaling behavior is predictable across the settings spectrum.

How This Combo Ranks

This CPU-GPU pairing ranks 1036 out of 3714 tested combinations for Microsoft Flight Simulator, placing it in the 72nd percentile of all systems evaluated. The ranking reflects the RTX 3080's position as a capable but not top-tier GPU for this title, combined with the Ryzen 7 7700X's strong single-threaded performance.

The CPU itself sits at the 85th percentile among all processors, with an average benchmark score of 35909. Its nearest rivals in the overall benchmark database include the AMD Ryzen 7 PRO 5845 (0.3% delta), Intel Core 7 250H (0.5% delta), AMD Ryzen AI 7 PRO 350 (0.5% delta), and Intel Core Ultra 9 185H (0.7% delta). These small deltas suggest that the 7700X is competitively positioned within its performance tier, though none of these rivals are direct contemporaries.

The GPU's 68th percentile ranking (average benchmark score of 23172) is lower than the CPU's percentile, indicating that the RTX 3080 is the weaker link in this pairing. Its nearest rivals — NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X — all have delta percentages below 0.5%, meaning the 3080 is not dramatically faster than these parts in synthetic benchmarks, despite being a more capable gaming GPU in practice.

The combo rank of 1036 out of 3714 suggests that while this system is not at the top of the leaderboard for Microsoft Flight Simulator, it outperforms the majority of tested configurations. The 4K Medium result of 73 FPS is a strong indicator that this combo can handle the simulator's most demanding scenarios at playable frame rates.

CPU Role

The AMD Ryzen 7 7700X contributes 8 cores and 16 threads based on the Zen 4 architecture, built on a 5 nm TSMC process with 6,570 million transistors in a 71 mm² die. Its base clock of 4.50 GHz and boost clock of 5.40 GHz are critical for Microsoft Flight Simulator, which relies heavily on single-threaded performance for its simulation logic and flight model calculations.

The CPU's cache hierarchy — 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3 — provides ample fast storage for the simulator's frequently accessed data. The dual-channel DDR5 memory support with 83.2 GB/s bandwidth ensures that the 16 threads can be fed with sufficient data, though the simulator's memory footprint can be substantial.

Benchmark results show the 7700X's strengths: a Cinebench R23 multicore score of 19088 and single-core score of 1987, with Geekbench scores of 12451 multicore and 2289 single-core. The PassMark multithread score of 35686 and single-thread score of 4190 further confirm its capabilities. In 3DMark tests, the CPU scores 8859 with 16 threads and 1090 single-threaded, showing that its multi-threaded scaling is strong but that its single-thread performance is the more relevant metric for this simulator.

The data shows that at 1080p, the CPU becomes the limiting factor at lower settings. The 1080p Low result of 158 FPS versus the 1440p Low result of 127 FPS (a 31 FPS difference) is smaller than the 1440p to 4K drop (33 FPS), suggesting that at 1080p, the CPU is preventing the GPU from reaching its full potential. The 1080p Ultra result of 88 FPS versus 1440p Ultra at 71 FPS (a 17 FPS difference) shows a similar pattern, where the CPU's frame generation capability caps performance at lower resolutions.

The CPU's 105 W TDP and unlocked multiplier allow for tuning, but the measured results reflect stock operation. Its 85th percentile ranking among all CPUs, with the nearest rivals being the Ryzen 7 PRO 5845 (0.3% delta), Core 7 250H (0.5% delta), Ryzen AI 7 PRO 350 (0.5% delta), and Core Ultra 9 185H (0.7% delta), positions it as a strong mid-range-to-high-end processor that pairs well with the RTX 3080 for this simulator, though the GPU remains the primary constraint at higher resolutions.
