Microsoft Flight Simulator

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 4070 Ti delivers a highly capable Microsoft Flight Simulator experience, but the data reveals a clear pattern of diminishing returns as settings increase. The RTX 4070 Ti sits in the 85th percentile of all GPUs, while the i5-9400 sits in the 50th percentile of all CPUs, creating a notable imbalance that becomes increasingly apparent at lower resolutions. The measured frame rates indicate that the GPU is the primary driver of performance at 4K, but the CPU begins to assert its influence as the resolution drops, creating a complex scaling picture across the twelve measured data points.

Settings Recommendations

The benchmark data strongly indicates that the High preset at 2560x1440 offers the most balanced experience, delivering 87.4 FPS while maintaining visual fidelity. At this resolution, the jump from High to Ultra yields only a marginal 1.4 FPS improvement (88.8 FPS versus 87.4 FPS), yet the visual cost of Ultra is substantial for a flight simulator where terrain and aircraft detail matter less than smooth frame pacing. The Medium preset at 2560x1440 achieves 106.9 FPS, which is a 22.3% improvement over High, but the visual compromise in a game that relies heavily on scenery detail is not justified when High already clears the 60 FPS threshold comfortably.

For 1080p users, the High preset at 102.5 FPS represents the sweet spot, as the Ultra preset at 103 FPS offers virtually no measurable benefit (a 0.5% difference) while the Low preset at 126.6 FPS sacrifices too much environmental detail for a 23.5% frame rate gain that is unnecessary on a 60Hz or even 144Hz display. The Medium preset at 117.5 FPS sits between these extremes, but the data shows that High provides the best visual-per-frame ratio. At 4K, the High preset at 63.7 FPS is the only viable option for sustained playability, as Ultra drops to 61.9 FPS (a 2.8% reduction) and Medium falls to 85.3 FPS but with significantly reduced visual quality. The Low preset at 4K achieves 105 FPS, but this is an outlier scenario where the GPU is no longer the bottleneck and the CPU’s limitations become the primary constraint.

GPU Role

The RTX 4070 Ti is built on the Ada Lovelace architecture with the AD104 chip, fabricated on a 5 nm process by TSMC. It features 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The GPU’s base clock runs at 2310 MHz, boosting to 2610 MHz, with memory clocked at 1313 MHz (21 Gbps effective). The card’s FP32 performance is rated at 40.09 TFLOPS, and it includes 7680 shading units, 240 TMUs, and 80 ROPs. These specifications place the GPU in the 85th percentile of all GPUs, with an average benchmark score of 44900.

In Microsoft Flight Simulator, the GPU’s role becomes evident when examining the measured FPS across resolutions. At 4K, the difference between Low (105 FPS) and Ultra (61.9 FPS) is 43.1 FPS, a 41% reduction, which demonstrates the GPU’s sensitivity to settings at this resolution. The 12 GB VRAM capacity is sufficient for this title at 4K, as the game’s texture streaming demands are substantial but not excessive. The GPU’s 504.2 GB/s memory bandwidth supports the high-resolution texture loads required for detailed terrain and aircraft models, and the 1:1 FP16/FP32 ratio of 40.09 TFLOPS indicates strong compute capability for the game’s physics and weather simulation systems.

Measured FPS Breakdown

At 1920x1080, the data shows the following average FPS values: Low at 126.6, Medium at 117.5, High at 102.5, and Ultra at 103. The progression from Low to Medium yields a 9.1 FPS drop (7.2%), while Medium to High drops 15 FPS (12.8%). Interestingly, High to Ultra shows a slight increase of 0.5 FPS, which suggests that the CPU is already limiting performance at this resolution, preventing the GPU from benefiting from the Ultra preset’s additional load. The 23.6 FPS gap between Low and Ultra (18.6%) is relatively narrow, confirming CPU involvement.

At 2560x1440, the measured values are: Low at 119.7, Medium at 106.9, High at 87.4, and Ultra at 88.8. The Low to Medium drop is 12.8 FPS (10.7%), Medium to High drops 19.5 FPS (18.2%), and High to Ultra shows a 1.4 FPS increase (1.6%). The widening gap between Low and Ultra (30.9 FPS, 25.8%) indicates the GPU is becoming more involved, but the High-to-Ultra anomaly persists, suggesting a CPU ceiling around the 88 FPS mark.

At 3840x2160, the values are: Low at 105, Medium at 85.3, High at 63.7, and Ultra at 61.9. The Low to Medium drop is 19.7 FPS (18.8%), Medium to High drops 21.6 FPS (25.3%), and High to Ultra drops 1.8 FPS (2.8%). The total Low to Ultra gap is 43.1 FPS (41%), which is the largest among all resolutions, confirming that the GPU is the dominant factor at 4K. The decreasing frame rate deltas at higher settings (from 19.7 to 21.6 to 1.8 FPS) suggest that the GPU’s rendering pipeline becomes saturated at High, with Ultra adding only marginal load.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals important information about the system’s limiting component. At Low settings, the 1080p score of 126.6 FPS drops to 119.7 FPS at 1440p (a 5.5% reduction) and then to 105 FPS at 4K (a 17.1% reduction from 1440p). The relatively small drop from 1080p to 1440p at Low settings (6.9 FPS) indicates that the CPU is the primary bottleneck at these lower resolutions and settings, as the GPU has spare capacity that cannot be utilized. However, the larger drop from 1440p to 4K (14.7 FPS) shows the GPU beginning to take on more work as pixel count increases.

At Ultra settings, the 1080p score of 103 FPS drops to 88.8 FPS at 1440p (a 13.8% reduction) and then to 61.9 FPS at 4K (a 30.3% reduction from 1440p). The consistent, substantial drops at Ultra settings across all resolution transitions indicate that the GPU is the limiting factor here, as the additional pixel load directly translates to lower frame rates. The contrast between Low and Ultra scaling patterns is stark: at Low, the 1080p-to-4K drop is 21.6 FPS (17.1%), while at Ultra, it is 41.1 FPS (39.9%). This suggests that at lower settings, the CPU caps performance around 105-127 FPS, while at higher settings, the GPU’s rendering workload becomes the bottleneck, particularly at 4K where the 63.7 FPS High score and 61.9 FPS Ultra score indicate the GPU is nearing its limits for this title.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, fabricated on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.10 GHz, with 9 MB of shared L3 cache and 256 KB of L2 cache per core. The CPU’s memory bandwidth is rated at 42.7 GB/s with dual-channel DDR4 support. In synthetic benchmarks, the i5-9400 scores 7969 in Cinebench R23 multi-core and 1125 in single-core, placing it in the 50th percentile of all CPUs with an average score of 2305.

The CPU’s role in Microsoft Flight Simulator is most evident at 1080p, where the frame rate differences between settings are compressed. The fact that High (102.5 FPS) and Ultra (103 FPS) produce nearly identical results at 1080p indicates that the CPU cannot feed the GPU fast enough to distinguish between these presets. This is consistent with the CPU’s 6-thread limitation, as flight simulators often exhibit single-thread-heavy workloads. At 1440p, the same pattern persists but with a slightly wider gap (87.4 FPS High versus 88.8 FPS Ultra), suggesting the GPU is taking on slightly more load. At 4K, the CPU’s influence diminishes as the GPU becomes the bottleneck, evidenced by the 63.7 FPS High and 61.9 FPS Ultra scores. The CPU’s 50th percentile ranking versus the GPU’s 85th percentile highlights this imbalance, and the measured data confirms that while the i5-9400 can sustain playable frame rates, it prevents the RTX 4070 Ti from reaching its full potential at lower resolutions and settings.
