Microsoft Flight Simulator

Microsoft Flight Simulator presents an unusually demanding workload that stresses both the CPU and GPU heavily. The measured data for the AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4070 Ti combination reveals a system that is capable of excellent performance across all resolutions, but the relationship between settings, resolution, and frame rate tells a nuanced story about where the bottlenecks lie. This analysis examines the measured FPS data to determine the optimal configuration, the role of each component, and how this pairing stacks up against other tested combinations.

Settings Recommendations

The measured FPS data across all resolutions indicates that the High preset offers the most balanced experience, delivering strong performance without sacrificing the visual fidelity that makes Flight Simulator immersive. At 1080p, High settings produce an average of 113 FPS, which is only 5 FPS lower than the Ultra preset's 108 FPS. However, the jump from Medium to High costs 37 FPS (from 150 to 113), while the jump from High to Ultra costs a mere 5 FPS. This suggests that the High preset captures nearly all of the visual benefits of Ultra at a fraction of the performance cost.

At 1440p, the pattern repeats. High settings deliver 91 FPS, which is only 4 FPS behind Ultra's 87 FPS. The gap between Medium (121 FPS) and High (91 FPS) is a substantial 30 FPS, indicating that the High preset requires significantly more GPU resources but remains entirely playable. At 4K, High settings produce 67 FPS, which is just 3 FPS ahead of Ultra's 64 FPS. This narrowing gap at higher resolutions suggests that the game becomes increasingly GPU-bound, and the difference between High and Ultra diminishes as the resolution increases.

For players with high refresh rate displays at 1080p or 1440p, the Medium preset provides a compelling alternative. At 1080p, Medium delivers 150 FPS with a minimum of 128 FPS, ensuring smooth gameplay even in demanding scenarios. At 1440p, Medium maintains 121 FPS with a minimum of 103 FPS. The Medium preset's minimum FPS values are particularly noteworthy—they are the only settings rows that include both minimum and maximum values, suggesting these runs were monitored more closely. The data implies that Medium offers a significant headroom advantage, making it the best choice for maintaining consistent frame times.

The Ultra preset is only recommended for 4K users with VRR displays. At 4K, Ultra averages 64 FPS, which is technically playable but leaves little margin for the complex scenes that can occur in dense urban areas or during weather events. The 3 FPS difference between High (67 FPS) and Ultra (64 FPS) at 4K makes High the logical choice even for the most demanding visual settings. The Low preset, while delivering impressive frame rates (193 FPS at 1080p), strips away too much of the simulation's visual detail to be considered a serious option for most users.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is the primary driver of frame rate differences across settings. With 12 GB of GDDR6X memory on a 192-bit bus providing 504.2 GB/s of bandwidth, the card has sufficient memory capacity for Flight Simulator's detailed terrain textures at 1080p and 1440p. The 4K data, however, suggests that the GPU is working near its limits. The transition from 1440p High (91 FPS) to 4K High (67 FPS) represents a 26% drop, and the Low preset shows an even larger drop from 156 FPS at 1440p to 115 FPS at 4K, a 26% reduction.

The card's boost clock of 2610 MHz and 7680 shading units deliver the raw compute necessary for the game's complex lighting and shadow calculations. The measured FPS scaling from Low to Ultra at each resolution reveals the GPU's performance envelope. At 1080p, the spread from Low (193 FPS) to Ultra (108 FPS) is 85 FPS, or 44% of the Low value. This spread narrows to 69 FPS at 1440p (156 to 87) and 51 FPS at 4K (115 to 64). The narrowing spread at higher resolutions indicates that the GPU is becoming the limiting factor, as the relative cost of each setting tier becomes smaller when the GPU is already saturated.

The RTX 4070 Ti's 60 RT cores and 240 Tensor cores suggest it has dedicated hardware for ray-traced effects and DLSS, but the measured data does not include any ray tracing or upscaling benchmarks. The raw rasterization performance, as measured by the passmark_g3d score of 31624 and the 3DMark Steel Nomad DX12 score of 5024, places the card in the 84th percentile of all GPUs. The nearest rivals in the benchmark database—the RTX 5090 Mobile, Radeon Pro 5500 XT, and RTX A6000—show that the RTX 4070 Ti trades blows with these very different cards, with delta percentages ranging from -1.7% to +1.6%.

Resolution Scaling

The measured data provides a clear picture of how frame rate scales with resolution, and the patterns reveal where the bottleneck shifts. At Low settings, the frame rate drops from 193 FPS at 1080p to 156 FPS at 1440p (a 19% reduction) and then to 115 FPS at 4K (a further 26% reduction). The 1080p to 1440p drop is relatively modest, suggesting the CPU can still feed the GPU efficiently at lower settings. The larger 1440p to 4K drop indicates the GPU is becoming the primary constraint.

At High settings, the scaling is more linear: 113 FPS at 1080p, 91 FPS at 1440p (a 19% drop), and 67 FPS at 4K (a further 26% drop). The consistent percentage drops across settings suggest that Flight Simulator scales predictably with resolution when the GPU is not the sole bottleneck. The Ultra settings show a similar pattern: 108 FPS at 1080p, 87 FPS at 1440p (a 19% drop), and 64 FPS at 4K (a 26% drop).

The Medium settings offer the most complete data, with min and max values recorded. At 1080p, the average is 150 FPS with a range of 128 to 173 FPS. At 1440p, the average drops to 121 FPS with a range of 103 to 139 FPS. At 4K, the average falls to 89 FPS with a range of 76 to 103 FPS. The minimum FPS values show that even at 4K Medium, the system never drops below 76 FPS, which is a strong indicator of playability. The max FPS values suggest that in less demanding scenes, the system can push significantly higher, but the averages reflect the typical experience.

The resolution scaling data strongly indicates that the RTX 4070 Ti is the limiting component at 4K. The fact that the 1080p to 1440p drop is nearly identical across all settings (19-20%) while the 1440p to 4K drop is also consistent (26-27%) suggests that the GPU's rendering pipeline is the primary constraint at all resolutions, but the CPU becomes more relevant at lower resolutions where the GPU can process frames faster.

CPU Role

The AMD Ryzen 9 9900X3D plays a crucial role in Flight Simulator's performance, particularly at lower resolutions where the GPU can produce frames faster than the CPU can feed it. With 12 cores and 24 threads based on the Zen 5 architecture, this processor provides substantial multi-threaded capability. The 3D V-Cache technology, which contributes to the 128 MB of L3 cache, is particularly well-suited for simulation games that rely on large datasets.

The CPU's benchmark scores support its strong performance. The Cinebench R23 multi-core score of 47737 and single-core score of 6739 place it in the 91st percentile of all CPUs. The Geekbench multi-core score of 22884 and single-core score of 3041 further confirm its capability. The 3DMark 16-thread score of 12490 and max-thread score of 13795 indicate that the processor scales well with additional threads.

The nearest CPU rivals in the benchmark database are the Intel Core Ultra 5 245KF, Core Ultra 5 245K, Xeon 6505P, and Core i7-14700F. The delta percentages range from -0.6% to +2.1%, showing that the 9900X3D is competitive with these processors but not dramatically ahead. This suggests that while the CPU is powerful, it may not be the primary differentiator in Flight Simulator's performance.

The base clock of 4.40 GHz and boost clock of 5.50 GHz provide excellent single-thread performance, which is critical for Flight Simulator's physics and flight model calculations. The 4 nm process node from TSMC and 16,630 million transistors indicate a modern, efficient design. The dual-die layout (2x 70.6 mm²) with 80 KB of L1 cache and 1 MB of L2 cache per core provides the low-latency access that simulation games require.

The CPU's role becomes more apparent when examining the Low settings data. At 1080p Low, the system achieves 193 FPS, which is a high enough frame rate that the CPU's ability to process the game's simulation logic becomes the limiting factor. The fact that the 1080p to 1440p drop at Low settings is only 19% (193 to 156 FPS) suggests that the CPU is still able to feed the GPU effectively at these frame rates. However, the 1440p to 4K drop of 26% indicates that the GPU takes over as the primary bottleneck at higher resolutions.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture of performance across all resolutions and settings. At 1920x1080, the system delivers excellent frame rates across the board. The Low preset achieves 193 FPS average, while Medium averages 150 FPS with a minimum of 128 FPS and maximum of 173 FPS. High settings produce 113 FPS, and Ultra delivers 108 FPS. The 1080p data shows that even at Ultra settings, the system maintains over 100 FPS, making this resolution ideal for high refresh rate displays.

At 2560x1440, performance remains strong but begins to show the GPU's limitations. Low settings deliver 156 FPS, while Medium averages 121 FPS with a range of 103 to 139 FPS. High settings produce 91 FPS, and Ultra delivers 87 FPS. The 1440p data reveals that the gap between High and Ultra narrows to just 4 FPS, suggesting that the GPU is approaching its limits at this resolution.

At 3840x2160, the system still delivers playable frame rates but with less headroom. Low settings achieve 115 FPS, while Medium averages 89 FPS with a range of 76 to 103 FPS. High settings produce 67 FPS, and Ultra delivers 64 FPS. The 4K data shows that the difference between High and Ultra narrows to just 3 FPS, confirming that the GPU is the dominant constraint at this resolution.

The Medium preset is the only setting that has complete data with both minimum and maximum FPS values across all resolutions. This provides valuable insight into frame time consistency. At 1080p, the 45 FPS range (128 to 173) represents a 30% variation from the average, while at 1440p the 36 FPS range (103 to 139) is a 30% variation. At 4K, the 27 FPS range (76 to 103) is also a 30% variation. This consistency in relative variation suggests that the game's frame time variability scales proportionally with resolution.

How This Combo Ranks

The AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4070 Ti combination ranks 298th out of 2996 tested combos in Microsoft Flight Simulator. This places the system in the top 9.9% of all tested configurations, indicating that it is a high-performance pairing that can handle the game's demanding requirements. The rank of 298 out of 2996 means there are 297 combinations that perform better, which is a relatively small number given the vast array of possible CPU and GPU pairings.

The ranking suggests that this combination is well-balanced for Flight Simulator. The CPU's strong single-thread performance and large cache capacity complement the GPU's substantial rendering power. The fact that the combo ranks in the top 10% indicates that users of this system will have a smooth experience at most settings and resolutions, with only the most demanding 4K Ultra configurations potentially showing limitations.

The percentile rankings of the individual components provide additional context. The CPU ranks in the 91st percentile of all CPUs, while the GPU ranks in the 84th percentile of all GPUs. The combo's overall ranking being slightly lower than the CPU's percentile but higher than the GPU's percentile suggests that the CPU's strengths help compensate for the GPU's relative position. This is particularly relevant for Flight Simulator, which is known to be CPU-intensive due to its complex simulation logic.

The nearest GPU rivals, including the RTX 5090 Mobile (delta -0.8%), Radeon Pro 5500 XT (delta -1.3%), and RTX A6000 (delta +1.6%), show that the RTX 4070 Ti is competitive with a range of very different cards. The small delta percentages indicate that the GPU's performance is well-established within its performance class. Similarly, the CPU's nearest rivals show deltas ranging from -0.6% to +2.1%, confirming that the 9900X3D is a solid mid-to-high-range processor that performs as expected.

The combination's rank of 298 out of 2996 is a strong result, but it also implies that there is room for improvement. Users seeking higher performance could consider pairing a more powerful GPU with this CPU, as the data suggests the CPU has sufficient headroom to support faster graphics cards, particularly at lower resolutions where the GPU is not the primary bottleneck.
