Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding flight simulation title that stresses both the CPU and GPU heavily depending on resolution and settings. This analysis examines the measured performance of the AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 5070 Ti across three resolutions and four quality presets. The data shows a system that scales predictably with resolution, with the GPU becoming the primary bottleneck at 4K while the CPU holds up well at lower resolutions. The combo ranks 376th out of 3714 tested combinations, placing it in the top tier of systems for this specific title.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate drops from 195 FPS at 1080p to 160 FPS at 1440p, then further to 118 FPS at 4K. This represents a 39.5% reduction from 1080p to 4K at Low settings, indicating that even at the lowest quality preset, the resolution scaling remains significant.

Moving to Medium settings, the average FPS figures are 154 at 1080p, 124 at 1440p, and 92 at 4K. The drop from 1080p to 1440p is 19.5%, while the drop from 1440p to 4K is 25.8%. This suggests that the GPU is increasingly the limiting factor as resolution climbs, since the percentage decline between successive resolution steps grows at higher pixel counts.

At High settings, the averages are 116 FPS at 1080p, 94 FPS at 1440p, and 69 FPS at 4K. The scaling from 1080p to 1440p shows an 18.9% reduction, while 1440p to 4K shows a 26.6% reduction. This consistent pattern across presets indicates that the RTX 5070 Ti’s rendering workload scales roughly with pixel count, though the 4K step imposes a disproportionately larger penalty.

Ultra settings produce the lowest frame rates: 110 FPS at 1080p, 89 FPS at 1440p, and 66 FPS at 4K. The 4K Ultra figure of 66 FPS is only 3 FPS below the High preset at the same resolution, suggesting that the Ultra preset’s additional graphical features have diminishing returns at higher resolutions. The gap between 1080p and 4K at Ultra is 40%, nearly identical to the Low preset’s 39.5% scaling.

The 1080p to 4K scaling at each preset — 39.5% for Low, 40.3% for Medium, 40.5% for High, and 40.0% for Ultra — demonstrates that resolution scaling is remarkably consistent regardless of quality settings. This consistency points to the GPU as the dominant performance limiter across all tested configurations, since the CPU’s workload does not change with resolution while the GPU’s pixel processing load increases substantially. The Ryzen 5 8400F, with its 6 cores and 12 threads, appears to provide sufficient headroom at 1080p, as evidenced by the 195 FPS Low result, but the frame rates at 4K are constrained by the GPU’s rendering throughput.

The 4K Ultra result of 66 FPS, while not extremely high, remains playable, and the 1080p Low result of 195 FPS demonstrates the system’s ability to exceed high refresh rate thresholds when settings are reduced.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best balance of visual quality and performance for this hardware combination. At 4K resolution, the High preset delivers 69 FPS on average, while the Medium preset achieves 92 FPS with a minimum of 78 FPS and maximum of 106 FPS. The Ultra preset drops to 66 FPS, only 3 FPS below High, suggesting that the Ultra preset’s additional visual features do not justify the performance cost at this resolution.

At 1440p, the Medium preset produces 124 FPS on average with a minimum of 106 FPS and maximum of 143 FPS. The High preset achieves 94 FPS, while Ultra manages 89 FPS. The Low preset reaches 160 FPS but sacrifices significant visual quality. For 1440p, the Medium preset appears optimal, as it provides frame rates well above 60 FPS with a comfortable minimum of 106 FPS that ensures smooth gameplay during complex flight scenes.

At 1080p, the Medium preset delivers 154 FPS on average with a minimum of 131 FPS and maximum of 177 FPS. The High preset achieves 116 FPS, while Ultra reaches 110 FPS. The Low preset produces 195 FPS but at substantial visual quality cost. The Medium preset at 1080p offers the best combination of frame rate and visual fidelity, with the minimum FPS of 131 ensuring no noticeable stuttering.

For users prioritizing visual quality over maximum frame rate, the High preset at 4K provides 69 FPS, which is generally considered acceptable for a flight simulator where precise controls matter more than ultra-smooth motion. The Ultra preset’s 66 FPS at 4K represents only a 4.3% reduction from High, meaning the visual upgrade may be worthwhile for those with G-Sync or FreeSync displays that can handle variable refresh rates.

The data suggests that Medium settings provide the most consistent experience across all three resolutions, with the minimum FPS values at each resolution (78 at 4K, 106 at 1440p, and 131 at 1080p) all remaining comfortably above 60 FPS. This makes Medium the recommended preset for users who want to maintain smooth performance across different display configurations.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all presets. The Low preset averages 195 FPS, which is the highest measured value in the entire dataset. The Medium preset averages 154 FPS with a minimum of 131 FPS and maximum of 177 FPS. The High preset averages 116 FPS, while the Ultra preset averages 110 FPS. The spread between Low and Ultra at 1080p is 85 FPS, representing a 43.6% reduction from the lowest to highest quality settings.

At 2560x1440, performance scales down proportionally. The Low preset averages 160 FPS, a 17.9% reduction from 1080p. The Medium preset averages 124 FPS with a minimum of 106 FPS and maximum of 143 FPS, representing a 19.5% reduction from 1080p. The High preset averages 94 FPS, an 18.9% reduction. The Ultra preset averages 89 FPS, a 19.1% reduction from its 1080p counterpart. The consistency of these reductions, all within the 17-20% range, indicates that 1440p imposes a uniform additional load on the GPU regardless of quality settings.

At 3840x2160, the performance drops are more pronounced. The Low preset averages 118 FPS, a 26.3% reduction from 1440p. The Medium preset averages 92 FPS with a minimum of 78 FPS and maximum of 106 FPS, a 25.8% reduction. The High preset averages 69 FPS, a 26.6% reduction. The Ultra preset averages 66 FPS, a 25.8% reduction. The 4K resolution consistently imposes a 25-27% performance penalty over 1440p across all presets, reinforcing the pattern that the GPU’s pixel throughput is the primary constraint at higher resolutions.

The minimum FPS data, available only for Medium settings, shows that the system maintains playable frame rates even under load. At 1080p Medium, the minimum of 131 FPS indicates no significant frame drops. At 1440p Medium, the minimum of 106 FPS remains well above 60 FPS. At 4K Medium, the minimum of 78 FPS still clears the 60 FPS threshold with headroom. These minimums suggest that the system avoids severe stuttering, which is critical for a flight simulator where smooth camera movement and instrument readability matter.

GPU Role

The NVIDIA GeForce RTX 5070 Ti features 16 GB of GDDR7 memory on a 256-bit bus, providing a memory bandwidth of 896.0 GB/s. This high bandwidth is essential for flight simulation, which streams large amounts of terrain and texture data. The GPU’s 8960 shading units, 280 texture mapping units, and 96 raster output units process this data efficiently, as evidenced by the measured frame rates.

The GPU’s clock speeds are 2295 MHz base and 2452 MHz boost, with memory running at 1750 MHz (28 Gbps effective). These clocks, combined with the 70 ray tracing cores and 280 tensor cores, enable the Blackwell 2.0 architecture to handle the complex lighting and shadow calculations required by Microsoft Flight Simulator. The GPU’s 43.94 TFLOPS of FP32 performance provides substantial compute headroom for the simulation’s physics and weather systems.

The 16 GB VRAM capacity proves sufficient for 4K Ultra settings, where the measured 66 FPS average indicates the GPU is not running out of memory. If VRAM were insufficient, the frame rates would show more severe degradation at 4K due to texture swapping. The fact that 4K Ultra achieves 66 FPS, only 3 FPS below High settings, suggests that the additional VRAM usage at Ultra does not cause performance cliffs.

The RTX 5070 Ti’s synthetic benchmark scores reinforce its capability. The PassMark G3D score of 32974 and Geekbench OpenCL score of 212363 indicate strong raw compute performance. The 3DMark Steel Nomad DX12 score of 6604 reflects modern API efficiency. The GPU’s 86th percentile ranking among all GPUs places it above average, though its nearest synthetic rivals include older architectures like the Radeon RX Vega 64, which achieves a nearly identical average score of 50001.

The GPU’s power characteristics, with a 300 W TDP and recommended 700 W PSU, suggest it can sustain high clocks under sustained load. The dual-slot cooler and 304 mm length indicate adequate thermal solution for extended flight sessions. The PCIe 5.0 x16 interface provides ample bandwidth for data transfer from the CPU and system memory.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, manufactured on TSMC’s 4 nm process. Its base clock of 4.20 GHz and boost clock of 4.70 GHz provide strong single-thread performance, which is critical for flight simulation’s main simulation thread. The 16 MB shared L3 cache helps reduce memory latency for frequently accessed game data.

The CPU’s synthetic benchmarks show balanced performance across workloads. The Cinebench R23 multicore score of 20851 and single-core score of 2943 indicate strong multi-threaded and single-threaded capability. The 3DMark single-thread score of 951 and 16-thread score of 6091 demonstrate consistent scaling across thread counts. The PassMark multithread score of 24389 and single-thread score of 3685 further confirm the CPU’s capability.

In Microsoft Flight Simulator, the CPU’s role is primarily to handle the simulation logic, including flight dynamics, weather simulation, and AI traffic. The 12 threads allow the game to distribute these workloads, while the high single-thread performance ensures the main simulation thread does not become a bottleneck. The measured frame rates at 1080p, where the GPU is less stressed, provide evidence of the CPU’s adequacy: the Low preset achieves 195 FPS, suggesting the CPU can feed frames well beyond typical display refresh rates.

The CPU’s memory bandwidth of 83.2 GB/s from dual-channel DDR5 support is sufficient for the game’s data streaming requirements. The PCIe Gen 4 interface with 20 lanes provides adequate bandwidth for the GPU and storage devices. The 65 W TDP indicates efficient power consumption, allowing sustained boost clocks without thermal throttling.

The Ryzen 5 8400F’s 77th percentile ranking among all CPUs places it slightly below the RTX 5070 Ti’s 86th percentile GPU ranking. This minor imbalance means the CPU is less likely to bottleneck the GPU at higher resolutions, where the GPU’s rendering workload dominates. At 1080p Low, the 195 FPS result approaches the upper limit of what the CPU can feed, but this is not a practical concern for most users.
