Microsoft Flight Simulator

Microsoft Flight Simulator is exceptionally demanding, and the combination of the AMD Ryzen 5 8400F and NVIDIA GeForce GTX 1070 produces a system that is firmly entry-level for this title. The benchmark data shows that this pairing is capable of playable frame rates, but only at specific settings and resolutions, with the GTX 1070 acting as the primary bottleneck at higher graphical presets. The overall combo rank of 3069 out of 3714 tested configurations places this system in the lower quartile, indicating that while it can run the simulator, it will not deliver a high-fidelity experience. The measured results reveal a clear hierarchy: performance scales predictably with resolution and settings, but the margins between them offer distinct trade-offs for the user.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and clearly exposes the GTX 1070 as the limiting component in this configuration. At 1080p with Low settings, the system achieves an average of 83 FPS, which is the highest score recorded for this combo. Moving to 1440p at the same Low preset drops the average to 67 FPS, a reduction of 16 FPS, or roughly 19%. The jump to 4K at Low settings further reduces the average to 49 FPS, which is a 34 FPS drop from the 1080p figure and a 41% decrease from the 1440p result. This scaling pattern is typical of a GPU-bound scenario; the GTX 1070's pixel throughput and memory bandwidth are being saturated as the resolution increases, directly impacting the frame delivery.

The trend becomes even more pronounced at higher quality settings. At the High preset, the average frame rate falls from 48 FPS at 1080p to 39 FPS at 1440p, and then down to 29 FPS at 4K. The difference between the 1080p and 4K results at High settings is a substantial 19 FPS, or approximately 40% of the 1080p performance. This indicates that the GPU's workload is scaling almost linearly with the pixel count, with no sign of the CPU (the Ryzen 5 8400F) stepping in to mitigate the loss. The 6-core, 12-thread processor has the headroom to feed the GPU, but the GTX 1070 simply cannot process the increased graphical data fast enough.

At the Ultra preset, the 4K average drops to 27 FPS, which is effectively unplayable for a smooth experience. The 1080p Ultra average of 46 FPS is also marginal, while the 1440p Ultra result of 37 FPS falls below the threshold for comfortable gameplay. The data strongly suggests that the GTX 1070's 8 GB of GDDR5 memory and 256-bit bus are insufficient for the high-resolution texture loads and complex shaders of Microsoft Flight Simulator. The simulator's vast, detailed environments are particularly punishing on the GPU's fill rate and memory bandwidth, making the GPU the definitive constraint across all tested configurations.

CPU Role

The AMD Ryzen 5 8400F, with its 6 cores and 12 threads, is not the primary performance limiter in this pairing. The CPU's benchmark results show it is a capable mid-range part, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943. Its position in the 77th percentile of all CPUs, with an average benchmark score of 25005, places it well above the GTX 1070's 47th percentile ranking. This disparity in relative strength is the key indicator: the CPU has more performance headroom than the GPU can utilize in most gaming scenarios. The 4.20 GHz base and 4.70 GHz boost clocks provide adequate single-thread performance, which is crucial for the simulator's simulation and AI logic threads.

The Ryzen 5 8400F's performance relative to its nearest rivals further confirms its role. It is virtually tied with the AMD Ryzen 5 7500F, with a delta of only 0.2%, and it is 0.3% ahead of the Intel Core i7-11850H and 0.4% ahead of the Intel Core i7-13620H. This shows that the CPU's compute capability is competitive with modern mid-range options. However, in the context of this game, this computational power is largely left on the table. The evidence for this is the consistent frame rate drop as resolution increases. If the CPU were the bottleneck, we would expect the frame rates to remain relatively stable across resolutions, as the CPU workload would be constant. Instead, the significant drops indicate that the GPU is struggling to keep up with the increased rendering load.

The CPU's architecture, Zen 4 on the 4 nm TSMC process, ensures it is efficient, but its performance is not the deciding factor in this system's gaming experience. The PassMark multi-thread score of 24389 and the 3DMark max-threads score of 6165 demonstrate solid multi-threading capability, which helps with the background tasks of the simulator. However, the data suggests that the GTX 1070 is the component that dictates the playable settings and resolutions. In essence, the Ryzen 5 8400F is a strong modern CPU that is being held back by an older, lower-tier GPU in this specific configuration.

Settings Recommendations

For a target of 60 FPS average, the only viable option at 1080p is the Low preset, which delivers an average of 83 FPS. This setting provides a comfortable margin above the target and ensures a smooth experience, though it will sacrifice visual fidelity. The Medium preset at 1080p, with an average of 64 FPS, is also a strong candidate, offering a better balance of visuals and performance while staying above the 60 FPS threshold. The High and Ultra presets at 1080p, with averages of 48 and 46 FPS respectively, fall short of the 60 FPS target and would result in a less fluid experience, particularly during fast maneuvers over detailed terrain.

At 1440p, the requirements become more stringent. The Low preset is the only one that achieves an average above 60 FPS, hitting 67 FPS. The Medium preset drops to 52 FPS, which is playable but not ideal for a smooth experience, and the High and Ultra presets fall to 39 and 37 FPS respectively, which are below the optimal range. For users with a 1440p monitor, the Low preset is the recommended choice for a high frame rate experience, while Medium is acceptable for those who prioritize visual quality over absolute smoothness.

At 4K, the system is under severe strain. The Low preset yields an average of 49 FPS, which is the only playable option, but it still falls below the 60 FPS target. The Medium preset averages 38 FPS, and the High and Ultra presets are effectively unplayable at 29 and 27 FPS respectively. The data clearly indicates that 4K gaming is not a realistic goal for this hardware combination. The best experience across all resolutions is found at 1080p with Medium settings, which delivers 64 FPS on average and provides a good balance between the simulator's demanding visuals and performance. This preset offers a significant visual upgrade over Low while maintaining a playable frame rate.

GPU Role

The NVIDIA GeForce GTX 1070 is the decisive factor in this system's Microsoft Flight Simulator performance, and its age and specifications are the reason for the low frame rates at higher settings. The GPU's benchmark scores are modest, with a Passmark G3D score of 13498 and an average benchmark score of 9780, placing it in the 47th percentile of all GPUs. Its nearest rivals are professional or older workstation cards like the AMD FirePro W5000 and the NVIDIA Quadro M2000M, with performance deltas of -0.2% and -0.5% respectively. This clearly places the GTX 1070 in a lower performance tier for modern, demanding games.

The GPU's 8 GB of GDDR5 memory and 256.3 GB/s of bandwidth are insufficient for the high-resolution texture packs and complex geometry of Microsoft Flight Simulator. At 4K with Ultra settings, the average frame rate plummets to 27 FPS, indicating that the GPU is overwhelmed by the data. The Pascal architecture, built on a 16 nm process, is also dated, lacking the more advanced features and efficiency of newer generations. The 150 W TDP and 267 mm length are not unusual, but the raw compute power, at 6.463 TFLOPS, is simply not enough for the simulator's heavy shader and lighting calculations.

The benchmark data shows a clear pattern: the GTX 1070's performance degrades rapidly as the graphical load increases. The difference between the Low and Ultra presets at 1080p is 37 FPS (83 vs 46), and at 4K it is 22 FPS (49 vs 27). This scaling demonstrates that the GPU is the limiting factor. Upgrading the CPU would likely yield little to no improvement in this game, as the Ryzen 5 8400F is already capable of feeding the GPU more data than it can process. The GTX 1070's 1920 shading units and 64 ROPs are just not enough to handle the simulator's vast draw distances and detailed environments at high resolutions.

Measured FPS Breakdown

The measured frame rates provide a comprehensive view of the system's capabilities, showing a clear and consistent scaling with both resolution and settings. At 1920x1080, the lowest resolution tested, the system performs best. With Low settings, it achieves an average of 83 FPS. Moving to Medium settings drops the average to 64 FPS, with a minimum of 55 FPS and a maximum of 74 FPS. The High preset yields an average of 48 FPS, while the Ultra preset results in an average of 46 FPS. This shows that at 1080p, the system can handle the lower presets well but struggles to maintain high frame rates on the more demanding ones.

At 2560x1440, the performance impact of the higher pixel count is immediate. The Low preset averages 67 FPS, which is still above the 60 FPS threshold but a noticeable drop from the 1080p result. The Medium preset averages 52 FPS (min 44, max 60), which is a playable but less smooth experience. The High and Ultra presets average 39 FPS and 37 FPS, respectively, indicating that these settings are not ideal for this resolution. The frame rate drops from 1080p to 1440p are consistent across all presets, ranging from a 16 FPS drop on Low to a 9 FPS drop on Ultra.

At 3840x2160, the system is pushed to its limits. The Low preset is the only one that achieves a marginally playable average of 49 FPS. The Medium preset averages 38 FPS (min 32, max 44), which is below the threshold for smooth gameplay. The High preset averages 29 FPS, and the Ultra preset averages 27 FPS, making both effectively unplayable for a continuous experience. The overall trend across all resolutions and settings is that the GTX 1070 is the limiting factor, with the Ryzen 5 8400F providing sufficient processing power to avoid becoming a bottleneck. The data confirms that for a playable experience, users should stick to 1080p with Medium settings or lower, or 1440p with Low settings.
