Microsoft Flight Simulator

The AMD Ryzen 7 9700X and NVIDIA GeForce RTX 3080 pairing delivers a playable but demanding experience in Microsoft Flight Simulator. The data shows this combination ranks 532nd out of 1795 tested combos in this game, placing it in the upper third of configurations. The measured results reveal a system that can handle the simulator's heavy loads, but the balance between the 8-core processor and the 10 GB graphics card shifts significantly depending on resolution and settings.

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

The Ryzen 7 9700X brings 8 cores and 16 threads running on the Zen 5 architecture, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. This is a 65 W desktop part on the AM5 socket, built on TSMC's 4 nm process. The processor's benchmark scores show strong single-thread performance, with a 3dmark single-thread score of 1280 and a Passmark single-thread score of 4654. These results matter because flight simulators typically rely heavily on a few main threads for physics, flight modeling, and scenery loading.

The multi-threaded results are equally robust. The Cinebench R23 multicore score of 31588 and the Passmark multithread score of 37161 indicate that the 9700X has ample headroom for background tasks like AI traffic and weather simulation. The processor sits at the 89th percentile among all CPUs tested, with an average benchmark score of 36029. Its nearest rivals include the Intel Core i5-14500HX, which scores 35940 (0.2% higher), and the Intel Core Ultra 9 185H, which scores 36165 (0.4% lower). This places the 9700X in a tight performance cluster where the differences between competing chips are minimal.

In Microsoft Flight Simulator, the CPU's job is to feed the GPU with draw calls and handle the complex world-streaming logic. The 32 MB of shared L3 cache helps keep frequently accessed data close to the cores. The integrated Radeon Graphics on this CPU are not relevant for gaming performance when a discrete GPU is present, but the processor's DDR5 memory support and dual-channel bus provide 89.6 GB/s of bandwidth, which is sufficient for the simulator's terrain and object data. The single-thread performance is particularly valuable here, as the game's frame pacing often depends on the fastest core rather than the total thread count.

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

The RTX 3080 is an Ampere-architecture card with 10 GB of GDDR6X memory on a 320-bit bus, providing 760.3 GB/s of bandwidth. The GPU runs at a base clock of 1440 MHz and a boost clock of 1710 MHz, with memory clocked at 1188 MHz (19 Gbps effective). This card was released in August 2020 and is now end-of-life, but its 8704 shading units and 68 RT cores still deliver substantial rasterization performance. The GPU sits at the 80th percentile among all graphics cards, with an average benchmark score of 35787.

The 10 GB VRAM capacity is the most significant constraint in this pairing. At 4K resolution with Ultra settings, the game requires more memory than the card physically has, which can lead to texture swapping and stuttering in dense areas. The card's nearest rivals include the AMD Radeon Pro Duo (35860, 0.2% higher), the AMD Radeon RX 7900 GRE (36101, 0.9% higher), and the NVIDIA GeForce RTX 5070 Ti Mobile (35435, 1% lower). These scores show that the 3080 remains competitive in raw compute, but the VRAM limitation becomes apparent in the measured FPS data.

For Microsoft Flight Simulator specifically, the GPU handles the rendering of terrain, aircraft models, and weather effects. The 760.3 GB/s memory bandwidth helps move large textures quickly, but the 10 GB capacity forces the game to use lower-resolution textures at higher settings. The 29.77 TFLOPS FP32 performance is more than adequate for the game's lighting and shadow calculations. The PCIe 4.0 x16 interface ensures the CPU can feed data to the GPU without bottlenecking, which is critical for a game that streams scenery tiles continuously.

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

The measured FPS data shows a clear pattern of scaling from 1080p to 4K. At High settings, the frame rate goes from 91.3 FPS at 1920x1080 to 73.9 FPS at 2560x1440 (a 19% drop), and then to 51.4 FPS at 3840x2160 (a 30% drop from 1440p). This steep decline at 4K indicates the GPU is becoming the limiting factor, as the pixel count quadruples from 1080p to 4K while the CPU workload remains relatively constant.

At Low settings, the scaling tells a different story. The 1080p result of 155.4 FPS drops to 124 FPS at 1440p (a 20% reduction) and then to 93.4 FPS at 4K (a 25% reduction). The fact that Low settings at 4K still produces 93.4 FPS shows the GPU has enough raw power to handle the resolution when the visual complexity is reduced. The CPU is still capable of maintaining high frame rates even at 4K, as evidenced by the 93.4 FPS result, which is higher than the High settings score at 1440p.

The gap between Low and High settings widens at higher resolutions. At 1080p, the difference between Low and High is 64.1 FPS (155.4 vs 91.3), while at 4K the difference is 42 FPS (93.4 vs 51.4). This narrowing gap suggests that at 4K, both settings are hitting a similar bottleneck — likely the VRAM capacity or the memory bandwidth. The 10 GB VRAM is likely insufficient for Ultra textures at 4K, causing the GPU to swap data more frequently, which caps the performance regardless of the settings preset.

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

At 1920x1080, the results show a wide spread across settings. Low settings produce 155.4 FPS, Medium 124.7 FPS, High 91.3 FPS, and Ultra 89.2 FPS. The jump from Medium to High is a significant 33.4 FPS drop, while the difference between High and Ultra is only 2.1 FPS. This suggests that High and Ultra presets are both hitting a similar CPU or GPU limit at this resolution, and the extra visual fidelity from Ultra comes at a minimal frame rate cost.

At 2560x1440, the performance scales down proportionally. Low settings hit 124 FPS, Medium 98.4 FPS, High 73.9 FPS, and Ultra 72.8 FPS. The gap between High and Ultra narrows further to just 1.1 FPS, indicating that the game is becoming more GPU-bound at this resolution. The drop from 1080p to 1440p at Medium settings is 26.3 FPS (124.7 to 98.4), which is a 21% reduction, consistent with the increased pixel count.

At 3840x2160, the results show the GPU struggling with the higher resolution. Low settings still produce a playable 93.4 FPS, but Medium drops to 74 FPS, High to 51.4 FPS, and Ultra to 54 FPS. Notably, Ultra produces a higher frame rate than High at 4K (54 vs 51.4), which is an anomaly in the data. This could be due to the game engine making different draw calls or texture loading decisions at Ultra, or it could be a measurement artifact. The gap between Medium and High is 22.6 FPS, which is the largest single-step drop in the entire dataset, highlighting the VRAM bottleneck at this resolution.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo rank of 532 out of 1795 tested combinations places this system in the 70th percentile of all configurations tested in Microsoft Flight Simulator. This means approximately 30% of the tested combos perform better. The ranking reflects the balance of the 9700X's strong CPU performance with the 3080's aging GPU capabilities. The CPU is clearly not the limiting factor, as its 89th percentile ranking among all CPUs is significantly higher than the combo's overall rank.

The GPU's 80th percentile ranking is closer to the combo's overall position, suggesting that the RTX 3080 is pulling the system down relative to the CPU's potential. The 10 GB VRAM is likely the primary reason the combo ranks where it does, as newer GPUs with 16 GB or 24 GB capacities can handle the game's texture demands more effectively. The measured FPS data confirms this, as the 4K Ultra result of 54 FPS is only marginally better than the High result of 51.4 FPS, indicating the GPU is running out of memory rather than computational power.

In the context of the nearest rival GPUs, the RTX 3080's performance scores are very close to the AMD Radeon RX 7900 GRE (0.9% lower) and the RTX 5070 Ti Mobile (1% higher). The combo's rank of 532 suggests that these small benchmark differences translate into meaningful in-game performance differences, likely due to the VRAM capacity and driver optimizations specific to this title.

Settings Recommendations — which preset gives the best experience per the measured rows

For a smooth experience at 1920x1080, the Medium preset at 124.7 FPS provides the best balance of visual quality and performance. High settings at 91.3 FPS are also playable, but the 33.4 FPS drop from Medium may not justify the visual improvement. Ultra at 89.2 FPS is nearly identical to High, so if you want the highest fidelity, the 2.1 FPS cost is negligible.

At 2560x1440, the Medium preset at 98.4 FPS is the recommended choice. It offers a substantial 24.5 FPS advantage over High (73.9 FPS) while still looking noticeably better than Low (124 FPS). The Ultra preset at 72.8 FPS is only 1.1 FPS behind High, so if you prefer the highest settings, the performance penalty is minimal.

At 3840x2160, the situation becomes more nuanced. The Low preset at 93.4 FPS is the only setting that delivers a truly smooth experience, but it sacrifices significant visual quality. The Medium preset at 74 FPS is acceptable for flight simulation, where slower camera movements and less fast-paced action make lower frame rates more tolerable. Avoid High and Ultra at 4K, as the 51.4 FPS and 54 FPS results respectively will be noticeably less smooth, and the VRAM limitation means you are not getting the intended visual fidelity anyway. The data indicates that 1440p Medium is the sweet spot for this combination, offering 98.4 FPS with good visual quality and avoiding the VRAM issues that plague the 4K Ultra setting.
