Microsoft Flight Simulator

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 pairing in Microsoft Flight Simulator delivers a solid, if not spectacular, experience. The data shows a combination that is heavily influenced by the simulator's demanding nature, where the CPU's 12 cores and 24 threads provide a strong foundation, but the GPU's 12 GB of memory and Ada Lovelace architecture become the primary drivers of visual fidelity at higher resolutions. This analysis breaks down the measured performance, how it scales, and where this combo stands among the thousands of tested configurations.

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

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It operates on the AMD Socket AM5 platform with a base clock of 4.40 GHz and a boost clock of 5.60 GHz. This high core count and boost capability are significant for a simulation like Microsoft Flight Simulator, which is known for its complex physics and AI calculations that can scale across multiple threads. The CPU's 64 MB of shared L3 cache is also beneficial for handling the large data sets associated with terrain and aircraft systems.

In the context of this game's results, the CPU's synthetic benchmark scores indicate its capability. For instance, its 3dmark single-thread score of 1286 and max-thread score of 13929 show a strong balance. More telling are the Cinebench scores: a multicore score of 19503 in R20 and 46438 in R23, alongside a single-core score of 6555 in R23. These figures suggest the 9900X has enough single-thread headroom for the main game loop, while its multi-threaded power ensures that background simulation tasks do not cause significant hitches. The CPU's percentile rank of 94 among all tested CPUs reinforces that it is a top-tier processor for this workload. When compared to its nearest rivals, it sits within a tight performance band: it is 0.4% behind the AMD Ryzen 9 9900X3D, 0.7% ahead of the Intel Core i7-14700F, and 1.5% behind the Intel Core Ultra 5 245K. This indicates that the 9900X is not the bottleneck in most scenarios, as its processing power is largely sufficient to feed the GPU.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the best performance I can expect from this combo at 1080p?

A: The highest measured average FPS at 1920x1080 is 166.8 FPS, but this is achieved with the "Low" settings preset. For a more visually demanding experience, the "High" preset yields 93.5 FPS, and "Ultra" yields 90.9 FPS.

Q: How does the combo perform at 4K resolution?

A: At 3840x2160, the performance drops significantly. The "Low" preset achieves 97 FPS, "Medium" hits 76.1 FPS, "High" reaches 58 FPS, and "Ultra" drops to 55.2 FPS. The 4K "Ultra" setting is the most demanding scenario measured.

Q: Is the CPU or the GPU more likely to be the limiting factor?

A: The data suggests the GPU becomes the primary limiter at higher resolutions. The FPS drop from 1080p to 4K is substantial (e.g., 93.5 FPS to 58 FPS on "High"), indicating that the rendering load on the RTX 4070 is the main constraint. The CPU's strong multi-threaded scores, such as a Cinebench R23 multicore result of 46438, suggest it is not holding the system back.

Q: What is the difference in performance between the "High" and "Ultra" presets?

A: The difference is modest at most resolutions. At 1440p, "High" delivers 80.1 FPS while "Ultra" delivers 75.3 FPS. At 4K, the gap is slightly wider, with "High" at 58 FPS and "Ultra" at 55.2 FPS. The visual uplift from "Ultra" does not come with a large performance penalty.

Q: How does this combo rank compared to all other tested combinations?

A: The combo ranks 411th out of 1795 tested combinations for this game. This places it in the top quarter of all systems, indicating a strong performance level, though not at the absolute top tier.

Q: Does the RTX 4070's memory size have any impact on the results?

A: The RTX 4070 features 12 GB of GDDR6X memory on a 192-bit bus, providing a bandwidth of 504.2 GB/s. While the benchmark results do not explicitly isolate memory capacity as a variable, the consistent performance across settings suggests that 12 GB is sufficient for the tested presets at these resolutions in this game.

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

The measured FPS data shows a clear and predictable scaling pattern as resolution increases. At 1920x1080 with "High" settings, the combo achieves 93.5 FPS. Moving to 2560x1440, that figure drops to 80.1 FPS, a reduction of 13.4 FPS. At 3840x2160, the "High" preset yields only 58 FPS, which is a 35.5 FPS drop from 1080p. This trend is consistent across all settings. For example, the "Medium" preset goes from 129.7 FPS at 1080p to 103.7 FPS at 1440p and then 76.1 FPS at 4K.

This behavior indicates that the system is becoming increasingly GPU-bound as resolution climbs. The RTX 4070's rendering workload is the primary factor behind the FPS decline. The CPU, with its high core count and strong single-thread performance, has enough headroom to maintain consistent frame pacing, but it cannot compensate for the GPU's inability to fill more pixels at the same rate. The data shows that the FPS penalty from 1440p to 4K is larger than the penalty from 1080p to 1440p, which is typical for a GPU-limited scenario. For instance, on "High" settings, the drop from 1080p to 1440p is 13.4 FPS, while the drop from 1440p to 4K is 22.1 FPS. This suggests that to achieve higher frame rates at 4K, a more powerful GPU would be the necessary upgrade, rather than a faster CPU.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Ryzen 9 9900X and RTX 4070 combination holds the 411th position out of 1795 tested combos in Microsoft Flight Simulator. This rank is a strong indicator of overall performance, placing it in the top 23% of all systems tested. The data suggests that this pairing is well-balanced for this specific game. The CPU's high percentile rank of 94 and the GPU's percentile rank of 81 combine to produce a system that does not have an obvious weak link.

When contextualizing this rank, it is important to note that many of the combos above it likely feature higher-tier GPUs, such as the RTX 4080 or 4090 series, which would provide the additional pixel-pushing power that this game demands at 4K. The 9900X's processing capability is sufficient to keep pace with the RTX 4070, as evidenced by the fact that it is not significantly outmatched by its nearest CPU rivals. In a game where frame rates can be highly variable, achieving a top-quartile rank shows that this setup is a reliable choice for a high-refresh-rate 1080p or 1440p experience, and a playable 4K experience with adjusted settings.

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

The following is the complete set of measured average FPS values for this CPU and GPU combination:

• 1920x1080 (1080p):
• Low: 166.8 FPS
• Medium: 129.7 FPS
• High: 93.5 FPS
• Ultra: 90.9 FPS

• 2560x1440 (1440p):
• Low: 133.9 FPS
• Medium: 103.7 FPS
• High: 80.1 FPS
• Ultra: 75.3 FPS

• 3840x2160 (4K):
• Low: 97 FPS
• Medium: 76.1 FPS
• High: 58 FPS
• Ultra: 55.2 FPS

These figures show a few key points. First, the "Low" preset at 1080p offers a very high frame rate, suggesting the CPU is not a bottleneck. Second, the gap between "High" and "Ultra" is minimal, with only a 2.6 FPS difference at 1080p and 2.8 FPS at 4K. This indicates that the "Ultra" preset's additional graphical features do not heavily tax the system. Third, the performance at 4K with "High" and "Ultra" settings hovers around the 55-58 FPS mark, which is playable but not ideal for competitive scenarios. The data shows a very clear progression: for every resolution, the "Low" preset provides the highest FPS, followed by "Medium," then "High," and finally "Ultra."

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

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution and desired frame rate.

For 1080p gamers, the "High" preset at 93.5 FPS is an excellent starting point, offering a strong balance between visual quality and smoothness. The "Ultra" preset provides a marginal 2.6 FPS penalty for a modest visual upgrade, making it a viable choice for those who prioritize image fidelity over a few extra frames. The "Low" preset is overkill for most, but the 166.8 FPS result makes it an option for those with very high refresh rate monitors.

At 1440p, the "High" preset delivers a solid 80.1 FPS, which is smooth for a flight simulator. The "Ultra" preset, at 75.3 FPS, remains comfortably playable and is the recommended setting for the best visual experience at this resolution, as the performance hit from "High" is only 4.8 FPS. The "Medium" preset at 103.7 FPS is a good choice for users who want to ensure a high frame rate with room to spare.

For 4K gaming, the situation is more constrained. The "High" preset achieves 58 FPS, which is close to the 60 FPS target, but the "Ultra" preset drops to 55.2 FPS. The "Medium" preset, at 76.1 FPS, is the best option for a smoother experience, offering a significant 18.1 FPS advantage over "High" with only a moderate reduction in visual quality. Given the minimal difference between "High" and "Ultra" (2.8 FPS), users at 4K should choose between "Medium" for fluidity or "High" for better visuals, but "Ultra" is only recommended for those who prioritize graphics above all else and can tolerate frame rates in the mid-50s.
