Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title, but the combination of the Intel Core i5-10400F and the NVIDIA GeForce RTX 5070 Ti delivers a robust experience across all tested settings. The benchmark data shows a clear pattern: the RTX 5070 Ti provides enough headroom to make the 6-core Comet Lake CPU the primary bottleneck at lower resolutions, while the load shifts to the GPU as resolution increases. The most balanced and visually impressive experience is achieved at 1440p with High settings, where the frame rate remains fluid without sacrificing the graphical fidelity that defines this simulator.

Settings Recommendations

The measured frame rates reveal a distinct performance hierarchy that favors higher resolutions for this specific pairing. At 1920x1080, the average frame rates are tightly clustered, with Low producing 134 FPS, Medium 123 FPS, High 110 FPS, and Ultra 109 FPS. This narrow 25 FPS spread indicates that the Intel Core i5-10400F is limiting the frame rate, as the GPU has spare capacity that the CPU cannot feed at this resolution. While 110 FPS at High is certainly smooth, the data suggests that the visual returns from stepping down to Medium or Low are minimal relative to the frame rate gains, indicating a CPU-bound scenario where the GPU is not being fully utilized.

Moving to 2560x1440, the performance scaling becomes more logical and GPU-oriented. Here, Low produces 125 FPS, Medium 114 FPS, High 94 FPS, and Ultra 89 FPS. The 4K-class GPU begins to show its strength, with a more pronounced drop from Low to Ultra that reflects the increased pixel load. The 94 FPS average at High settings is an excellent result for a flight simulator, offering a substantial improvement in visual quality over the 1080p results without compromising smoothness. The 25 FPS difference between Low and Ultra at this resolution (125 vs 89 FPS) shows the GPU is now the primary driver of performance.

At 3840x2160, the RTX 5070 Ti asserts its dominance, but the demands of 4K are severe. The Ultra preset yields 66 FPS, while High produces 69 FPS, a negligible 3 FPS difference that suggests both presets are pushing the GPU to its limits. Medium provides a more comfortable 92 FPS, and Low jumps to 113 FPS. The data indicates that for the best experience at 4K, the Medium preset is the sweet spot, delivering a 92 FPS average with a minimum of 78 FPS, which is well within the playable range for a simulator. The High and Ultra presets, while visually stunning, dip close to the 60 FPS threshold, which may be less desirable for a game that requires precise control.

The optimal recommendation is the High preset at 2560x1440. This configuration achieves a 94 FPS average, which is high enough to ensure a fluid experience, while the graphical settings provide the detailed terrain and aircraft models that are central to the simulation. At 1080p, the CPU bottleneck makes the choice less critical, but High remains a sensible default. For 4K users, Medium is the recommended preset to maintain performance above 90 FPS, as the jump to High or Ultra yields diminishing returns in frame rate for a significant increase in rendering load.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the dominant component in this pairing, equipped with 16 GB of GDDR7 memory on a 256-bit bus, providing a substantial 896.0 GB/s of bandwidth. Its Blackwell 2.0 architecture, built on a 5 nm process at TSMC, packs 45,600 million transistors into a 378 mm² die. The GPU operates at a base clock of 2295 MHz and a boost clock of 2452 MHz, with memory running at 1750 MHz (28 Gbps effective). These specifications translate to a pixel rate of 235.4 GPixel/s and a texture rate of 686.6 GTexel/s, making it exceptionally well-suited for the high-resolution texture streaming that Microsoft Flight Simulator requires.

The benchmark results underscore the GPU's capability, particularly in the context of this simulator. The RTX 5070 Ti scores 32,974 in the Passmark G3D test and 20,203 in the GPU Compute test, placing it in the 86th percentile of all GPUs. Its nearest rivals in the database include the AMD Radeon RX Vega 64, which scores 50,001 with a delta of -0.1%, and the Intel Arc A550M at 49,737 with a delta of 0.4%. This indicates that while the RTX 5070 Ti is highly competitive, it is not at the absolute top of the performance stack, yet its 16 GB frame buffer is a critical asset for a game that loads vast amounts of terrain data.

In practice, the GPU's role becomes more pronounced as resolution increases. At 1080p, the frame rates across presets (109-134 FPS) suggest the CPU is the limiting factor, as the GPU cannot stretch its legs. At 1440p, the GPU begins to influence performance more, with the gap between Low and Ultra widening to 36 FPS. At 4K, the GPU is fully engaged, and the 66 FPS Ultra result shows the immense computational load of rendering a flight simulator at that resolution. The data shows a clear progression: the RTX 5070 Ti is a high-end card that scales effectively with resolution, but its full potential is only realized when paired with a stronger CPU at lower settings or when pushed to 4K.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly illustrates the shifting bottleneck between the CPU and GPU. At 1080p High, the average FPS is 110. At 1440p High, it drops to 94 FPS, a decrease of 16 FPS or roughly 15%. At 4K High, the average falls to 69 FPS, which is a 41 FPS drop from 1080p. This steep decline at 4K, compared to the more moderate decline from 1080p to 1440p, shows that the GPU is being progressively saturated as pixel count increases.

The pattern is consistent across other presets. At Medium settings, the FPS goes from 123 (1080p) to 114 (1440p) to 92 (4K), with the largest drop occurring between 1440p and 4K. At Low settings, the progression is 134 to 125 to 113, showing a smaller absolute drop but still indicating GPU limitation at 4K. The Ultra preset shows the most significant scaling: 109 FPS at 1080p, 89 FPS at 1440p, and 66 FPS at 4K, a total drop of 43 FPS from the lowest to highest resolution.

This data indicates that at 1080p, the CPU is the limiting factor, as the GPU has enough headroom to render frames faster than the CPU can process them. The relatively small FPS differences between presets at 1080p (134 Low vs 109 Ultra) confirm this. At 4K, the RTX 5070 Ti is the clear bottleneck, as the frame rates across presets are more compressed (113 Low vs 66 Ultra) and the absolute numbers are much lower. The limiting component is resolution-dependent, with the CPU holding back performance at 1080p and the GPU becoming the primary constraint at 4K, particularly on the higher presets.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, built on Intel's 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with a 12 MB shared L3 cache. The CPU supports DDR4 memory in a dual-channel configuration with a bandwidth of 42.7 GB/s. It connects via PCIe Gen 3 with 16 lanes. In synthetic benchmarks, it scores 10,283 in Cinebench R23 multi-core, 1,451 in single-core, and 12,115 in Passmark multithread, placing it in the 68th percentile of all CPUs.

In the context of Microsoft Flight Simulator, the CPU's role is significant but secondary to the GPU. The game is known for its complex flight physics and world simulation, which rely heavily on CPU performance. However, the benchmark data shows that at higher resolutions, the GPU dominates the frame rate. At 1080p, the CPU's limitations are apparent, as the frame rates do not scale much with GPU settings, hovering around 110-134 FPS. This suggests the 6 cores and 12 threads are sufficient to feed the GPU at this resolution, but they cannot push beyond that threshold.

At 1440p and 4K, the CPU's influence wanes, as the GPU becomes the bottleneck. The 4.30 GHz boost clock helps maintain decent single-thread performance, which is crucial for the game's primary simulation thread. The CPU's 68th percentile ranking is respectable, and its benchmark scores are competitive with rivals like the Intel Xeon 6756E (14,163 avg) and AMD EPYC 7552 (14,115 avg). While a stronger CPU would yield higher frame rates at 1080p, the data indicates that the Core i5-10400F provides a stable foundation for the RTX 5070 Ti, allowing the GPU to deliver excellent performance at higher resolutions, which is where this combo excels.
