How This Combo Ranks

The combo rank of 251 out of 2,996 tested configurations places this system firmly in the upper echelon of results for Microsoft Flight Simulator. This positioning reflects a balanced pairing where neither component becomes a glaring bottleneck at the tested settings. The CPU’s percentile versus all CPUs is 91, meaning it outperforms 91% of all processors in the benchmark database, while the GPU’s percentile is 86, outperforming 86% of all graphics cards. The combination of a top-decile CPU and a high-percentile GPU yields a system that handles the simulator’s complex scenery rendering and physics calculations without significant frame rate collapses.

Examining the CPU’s nearest rivals provides context for its synthetic benchmark standing. The AMD Ryzen 9 9900X3D posts an average benchmark score of 54,762, which is 0.6% lower than the Intel Core Ultra 5 245KF’s 55,093. However, it leads the Intel Core Ultra 5 245K by 1.3% (54,053) and the Intel Xeon 6505P by 2% (53,701). The most notable comparison is against the Intel Core i7-14700F, which scores 53,620 — the Ryzen is 2.1% ahead. These delta percentages are small, indicating that in synthetic workloads, the 9900X3D is competitive with, but not decisively superior to, these mid-to-high-range rivals. In Microsoft Flight Simulator specifically, the measured FPS data suggests that the CPU’s 3D V-Cache technology and high boost clock of 5.50 GHz contribute to strong frame pacing, as evidenced by the 4K Medium minimum FPS of 78 being a mere 15% below the average of 92.

The GPU’s nearest rivals show a similar pattern of tight competition. The RTX 5070 Ti’s average benchmark score is 49,957, which is 0.1% lower than the AMD Radeon RX Vega 64’s 50,001 and 0.4% higher than the Intel Arc A550M’s 49,737. More relevant comparisons for modern gaming are the AMD Radeon RX 6900 XT at 50,951 (2% higher than the RTX 5070 Ti) and the RX 6800 XT at 48,477 (3.1% lower). Despite the RX 6900 XT holding a slight synthetic advantage, the RTX 5070 Ti’s 16 GB of GDDR7 memory and 896.0 GB/s bandwidth prove sufficient for Microsoft Flight Simulator’s demanding textures at 4K, as the measured 4K Ultra average of 66 FPS demonstrates.

The rank of 251 out of 2,996 means this combo beats approximately 91.6% of all tested configurations. This is a strong result for a flight simulator that is notoriously demanding on both CPU and GPU. The data suggests that users can expect a smooth experience at 1440p with all settings maxed out, and only the most demanding 4K Ultra preset pushes the average below 70 FPS.

Resolution Scaling

The measured FPS data reveals a consistent pattern of performance scaling across resolutions, with the most significant drops occurring when moving from 1440p to 4K. At Low settings, the average FPS progresses from 198 at 1080p to 160 at 1440p (a 19.2% drop) and then to 118 at 4K (a 26.3% drop from 1440p). This scaling indicates that at Low settings, the CPU becomes a more significant factor, as the GPU has less work to do, and the Ryzen’s strong single-thread performance helps maintain high frame rates.

At Medium settings, the pattern shifts. The average FPS at 1080p is 154, dropping to 124 at 1440p (a 19.5% decrease) and then to 92 at 4K (a 25.8% decrease from 1440p). The minimum FPS values also scale: 131 at 1080p, 106 at 1440p, and 78 at 4K. This consistent ~20% drop per resolution step suggests that both CPU and GPU are being utilized more evenly, with the GPU’s 16 GB memory and 896.0 GB/s bandwidth handling the increased pixel count without a disproportionate penalty.

High settings show a similar trend: 116 FPS at 1080p, 94 at 1440p (a 19.0% drop), and 69 at 4K (a 26.6% drop from 1440p). The percentage drops are nearly identical to Medium, indicating that the performance scaling is resolution-bound rather than settings-bound. The larger drop from 1440p to 4K (around 26%) compared to 1080p to 1440p (around 19%) suggests that at 4K, the GPU’s fill rate and memory bandwidth become more critical, while at lower resolutions, the CPU’s 5.50 GHz boost clock and 128 MB L3 cache can better feed the GPU.

Ultra settings exhibit the smallest absolute differences between resolutions: 110 FPS at 1080p, 89 at 1440p (a 19.1% drop), and 66 at 4K (a 25.8% drop from 1440p). The fact that 4K Ultra (66 FPS) is only 40% lower than 1080p Ultra (110 FPS) shows that the RTX 5070 Ti’s 43.94 TFLOPS of FP32 performance and 686.6 GTexel/s texture rate provide substantial headroom. However, the data clearly indicates that the limiting component at 4K is the GPU, as the CPU’s performance metrics (Cinebench R23 multi-core 47,737, single-core 6,739) are strong enough to avoid bottlenecking at any resolution.

The scaling analysis reveals that the combo is CPU-bound at 1080p Low (198 FPS), where the GPU is likely idling, and GPU-bound at 4K Ultra (66 FPS), where the CPU has plenty of headroom. The sweet spot for this pairing is 1440p, where the FPS ranges from 89 at Ultra to 160 at Low, providing flexibility for different refresh rates and visual preferences.

Measured FPS Breakdown

1920x1080: The lowest resolution tested shows the combo’s maximum potential. At Low settings, the average FPS is 198, which is the highest recorded across all tested configurations. Medium settings produce a 154 FPS average with a minimum of 131 and maximum of 177, indicating consistent frame delivery without significant stutter. High settings yield 116 FPS average, while Ultra settings produce 110 FPS average. The narrow gap between High (116) and Ultra (110) — only 5.2% — suggests that at 1080p, the CPU’s 12 cores and 24 threads are sufficient to maintain high frame rates even with all settings maxed out. The 198 FPS at Low demonstrates that the RTX 5070 Ti is capable of extremely high frame rates when not constrained by graphical fidelity.

2560x1440: This resolution provides the best balance of visual quality and performance. Low settings average 160 FPS, which is 19.2% lower than 1080p Low, showing a mild GPU load increase. Medium settings average 124 FPS with a minimum of 106 and maximum of 143 — the minimum of 106 indicates that even in demanding scenes, the frame rate stays above 100 FPS. High settings produce 94 FPS average, which is suitable for 90 Hz displays. Ultra settings yield 89 FPS average, which is only 5.3% lower than High, indicating that the Ultra preset’s additional effects are handled efficiently by the GPU’s 16 GB memory and 896.0 GB/s bandwidth. The 1440p results show that this combo can drive high-refresh-rate monitors at Medium and High settings, while Ultra remains viable for 60-90 Hz panels.

3840x2160: At 4K, the GPU becomes the primary bottleneck, but the results remain playable. Low settings average 118 FPS, which is 26.3% lower than 1440p Low, and still exceeds 100 FPS. Medium settings average 92 FPS with a minimum of 78 and maximum of 106 — the minimum of 78 is the lowest recorded across all resolutions and settings, but it remains above the 60 FPS threshold for smooth gameplay. High settings average 69 FPS, which is borderline for 60 Hz displays but acceptable for a flight simulator. Ultra settings average 66 FPS, which is the lowest result in the entire dataset but still playable. The drop from Low (118) to Ultra (66) at 4K is a 44.1% reduction, highlighting the GPU’s workload at this resolution. The min/max data for 4K Medium (78-106) shows a 35.9% spread, indicating that the frame rate varies significantly based on the scene complexity, which is typical for a flight simulator with dynamic weather and terrain.

Across all resolutions, the Medium settings provide the most complete data with min/max values, allowing for a detailed analysis of frame pacing. At 1080p Medium, the spread is 131-177 (26.0% variance), at 1440p Medium it’s 106-143 (25.9% variance), and at 4K Medium it’s 78-106 (26.4% variance). This consistent variance suggests that the game’s performance fluctuations are inherent to the simulator’s engine rather than a specific hardware limitation.

CPU Role

The AMD Ryzen 9 9900X3D plays a critical role in Microsoft Flight Simulator’s performance, particularly at lower resolutions where the GPU is less stressed. The CPU’s 12 cores and 24 threads, based on the Zen 5 architecture (Granite Ridge), provide a robust foundation for the simulator’s complex physics and AI calculations. The base clock of 4.40 GHz and boost clock of 5.50 GHz are among the highest in the dataset, ensuring rapid single-thread performance for the game’s main simulation loop.

The CPU’s benchmark scores illustrate its capability. The Cinebench R23 multi-core score of 47,737 and single-core score of 6,739 are strong indicators of both multi-threaded and single-threaded performance. The 3DMark scores show scaling from 2,512 with 2 threads to 13,795 with max threads, with 8 threads yielding 9,002. This scaling suggests that the CPU efficiently utilizes its cores, with a 5.5x improvement from 2 to max threads. The Geekbench multi-core score of 22,884 and single-core of 3,041 further confirm the CPU’s balanced capabilities.

The 128 MB L3 cache is particularly relevant for Microsoft Flight Simulator, which streams large amounts of terrain and scenery data. The cache structure (80 KB L1 per core, 1 MB L2 per core) provides rapid access to frequently used data, reducing the need to fetch from DDR5 memory. The dual-channel DDR5 memory support with 89.6 GB/s bandwidth ensures that data can flow quickly between the CPU and memory, though the large L3 cache mitigates the need for constant memory access.

In the measured FPS data, the CPU’s influence is most apparent at 1080p Low, where the average FPS of 198 likely approaches the CPU’s limit in the game’s engine. The fact that 4K Low (118 FPS) is 40.4% lower than 1080p Low (198 FPS) while 4K High (69 FPS) is 40.5% lower than 1080p High (116 FPS) suggests that the scaling is consistent regardless of settings, pointing to a GPU limit at 4K rather than a CPU constraint. The CPU’s percentile of 91 versus all CPUs means it outperforms the vast majority of processors, and its nearest rivals (Intel Core Ultra 5 245KF at 55,093 avg score, 0.6% higher) are closely matched in synthetic benchmarks, but the Ryzen’s 3D V-Cache technology (though the vCache3d field is null, the 128 MB L3 cache is confirmed) likely provides an edge in cache-sensitive workloads like flight simulation.

The CPU’s high boost clock of 5.50 GHz is critical for maintaining high frame rates in scenarios with heavy single-threaded tasks, such as simulating multiple aircraft or complex weather systems. The PassMark single-thread score of 4,646 reflects this strength, and the multi-thread score of 56,154 shows that the CPU can handle background tasks without impacting game performance.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user’s resolution and refresh rate priorities. For 1080p users with high-refresh-rate monitors (144 Hz or above), the High preset at 116 FPS average provides an excellent balance of visual quality and smoothness. The Ultra preset at 110 FPS is nearly identical in performance (only 5.2% lower) and offers maximum visual fidelity, making it the recommended choice for 1080p unless the user prioritizes frame rates above 110 FPS. The Low preset at 198 FPS is only recommended for competitive play or if the user has a 165 Hz or higher monitor and prioritizes frame rate above all else.

For 1440p, the Medium preset at 124 FPS average with a minimum of 106 FPS is the best choice for high-refresh-rate displays, as it maintains frame rates above 100 FPS even in demanding scenes. The High preset at 94 FPS is suitable for 90-100 Hz monitors and provides improved visual quality. The Ultra preset at 89 FPS is the best choice for users with 60-90 Hz displays who want maximum visual fidelity without dropping below 60 FPS. The Low preset at 160 FPS is overkill for most monitors and sacrifices too much visual quality.

For 4K, the Medium preset at 92 FPS average with a minimum of 78 FPS is the recommended choice, as it provides smooth gameplay with a comfortable margin above 60 FPS. The High preset at 69 FPS is acceptable for 60 Hz displays but offers no headroom for demanding scenes. The Ultra preset at 66 FPS is the most visually impressive but risks dropping below 60 FPS in complex scenarios, making it a choice only for users who prioritize graphics over frame rate stability. The Low preset at 118 FPS is unnecessary at 4K, as the visual quality reduction is significant for marginal frame rate gains.

The data clearly shows that the Medium preset offers the best overall experience across all resolutions. At 1080p, it delivers 154 FPS with a minimum of 131; at 1440p, it delivers 124 FPS with a minimum of 106; and at 4K, it delivers 92 FPS with a minimum of 78. These results provide a consistent 25-35% performance buffer above the minimum playable threshold, ensuring that the simulator remains responsive during complex scenes with dense scenery or weather effects. For users who want the best visual experience without compromising playability, the High preset at 1440p (94 FPS) or 1080p (116 FPS) is a strong alternative, while the Ultra preset is best reserved for 1080p (110 FPS) where the performance penalty is minimal.
