Microsoft Flight Simulator

The pairing of the Intel Core i7-13700K with the NVIDIA GeForce RTX 5070 in Microsoft Flight Simulator presents a dataset where the CPU’s substantial core count meets a GPU with a 192-bit memory interface. The measured frames per second (FPS) across resolutions and settings reveal a system that is consistently capable, but the scaling patterns suggest a nuanced balance between the two primary components. This analysis interprets the provided benchmark data to explore how this specific combination behaves in one of the most demanding simulation titles available.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-13700K is a 16-core processor with 24 threads, built on the Raptor Lake architecture. Its base clock of 3.40 GHz and boost clock of 5.40 GHz are key specifications for a flight simulator that relies on single-thread performance for core simulation logic. The CPU’s benchmark scores reflect its strength: a Cinebench R23 multi-core score of 30745 and a single-core score of 2116 indicate a processor capable of handling both the complex physics calculations and the background tasks that Microsoft Flight Simulator generates.

In the measured results, the CPU’s influence is most apparent when examining the lower settings at 1080p. At Low settings, the system achieves 176 FPS, which is the highest recorded average in the dataset. This high frame rate suggests that at these settings, the GPU is not being fully stressed, allowing the CPU’s strong single-thread performance to push the frame rate upward. The processor’s PassMark single-thread score of 4333 supports this, as it indicates strong per-core capability that is critical for the game’s main thread.

The CPU’s 30 MB of shared L3 cache and 2 MB per-core L2 cache are also relevant. Flight simulation often involves loading large amounts of terrain and aircraft data, and a larger cache can help reduce latency when accessing this information. The benchmark results show that as resolution increases, the gap between Low and High settings narrows, which is a classic sign of the GPU becoming the primary bottleneck. However, the CPU’s ability to maintain high frame rates at 1080p Low, where the GPU has less work to do, suggests it is not holding the system back at these lower resolutions.

The CPU holds an 89th percentile ranking against all tested CPUs, with an average benchmark score of 46881. Its nearest rival, the AMD Ryzen 9 5900, scores 46971, a negligible -0.2% difference. This places the i7-13700K in a performance tier where it is effectively tied with its closest competitors, meaning the CPU is not a differentiator in this system configuration. The data indicates that the processor provides a solid foundation, but the visual fidelity and resolution chosen will determine where the performance limit lies.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5070 is equipped with 12 GB of GDDR7 memory on a 192-bit bus, delivering a bandwidth of 672.0 GB/s. The memory clock runs at 1750 MHz, with an effective rate of 28 Gbps. For Microsoft Flight Simulator, which is known for streaming high-resolution textures, the 12 GB capacity is a factor, but the memory bandwidth is equally important for moving that data quickly. The GPU’s boost clock of 2512 MHz and its 6144 shading units provide the raw processing power needed for the game’s complex rendering.

The GPU’s role becomes clearer when analyzing the scaling from 1080p to 4K. At 1080p Ultra, the system averages 98 FPS, while at 4K Ultra, it drops to 58 FPS. This 40 FPS drop as resolution increases is substantial and points to the GPU being the limiting factor at higher resolutions. The RTX 5070’s PassMark G3D score of 29137 and its 82nd percentile ranking against all GPUs show it is a capable card, but the demands of 4K in this simulator strain its resources.

The GPU’s 12 GB VRAM is a notable specification for this game. While the measured data does not show VRAM usage, the capacity is sufficient for most scenarios at High settings, as evidenced by the playable 61 FPS average at 4K High. However, the drop to 58 FPS at 4K Ultra suggests that the extra texture detail may be pushing the memory system harder. The GPU’s nearest rival, the AMD Radeon Pro 580, scores 40318 against the RTX 5070’s 40377, a 0.1% difference, indicating that in synthetic benchmarks, this card is positioned in a specific performance tier that is distinct from the CPU’s near-tie with its rivals.

The data suggests that the GPU is the component that determines the ceiling for visual quality. At 1080p, the system has headroom, but as the pixel count increases, the RTX 5070’s workload grows exponentially. The 58 FPS at 4K Ultra is the lowest measured average, and while it is still playable, it indicates that the GPU is working at its limit with this CPU.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data provides a clear picture of how the system scales across resolutions. Looking at the High settings preset, the frame rate drops from 103 FPS at 1080p to 83 FPS at 1440p, and then to 61 FPS at 4K. This represents a 40.8% drop from 1080p to 4K. Similarly, the Medium preset shows a drop from 137 FPS at 1080p to 110 FPS at 1440p, and further to 81 FPS at 4K, a 40.9% decrease. This consistent scaling pattern is a strong indicator that the GPU is the limiting component at higher resolutions.

The Low settings preset shows a different behavior. At 1080p Low, the system hits 176 FPS, which drops to 142 FPS at 1440p and 105 FPS at 4K. The percentage drop from 1080p to 4K here is 40.3%, which is very similar to the High and Medium presets. This uniform scaling across all presets suggests that the GPU’s workload is scaling linearly with pixel count, and the CPU is not introducing a bottleneck that would cause a non-linear drop.

The data implies that Microsoft Flight Simulator is heavily GPU-bound when paired with this CPU. The i7-13700K has enough headroom to feed the RTX 5070 at all tested settings and resolutions. The frame rate differences between settings at the same resolution are also telling. At 4K, the difference between Low and Ultra is 47 FPS (105 vs 58), which is a significant gap that highlights the GPU’s sensitivity to graphical fidelity. This is expected for a simulator that uses detailed terrain and lighting effects.

The FPS drop from 1080p to 1440p is also worth examining. For High settings, the drop is 20 FPS (103 to 83), which is a 19.4% decrease. From 1440p to 4K, the drop is 22 FPS (83 to 61), a 26.5% decrease. The larger percentage drop at higher resolutions confirms that the GPU is working progressively harder as pixel count increases, and the RTX 5070’s 192-bit memory bus may be a factor in this performance degradation.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The dataset provides 12 distinct measurements, spanning three resolutions and four settings presets. Each measurement is an average FPS, with some also including minimum and maximum values for the Medium preset. The following breakdown details the exact numbers from the fact pack.

At 1920x1080, the system achieves its highest frame rates. The Low preset yields an average of 176 FPS. The Medium preset produces an average of 137 FPS, with a minimum of 116 FPS and a maximum of 157 FPS. The High preset drops to 103 FPS, and the Ultra preset yields 98 FPS. This shows a 78 FPS difference between Low and Ultra at 1080p, indicating that the GPU has significant headroom at this resolution, even with the most demanding settings.

Moving to 2560x1440, the frame rates decrease across all presets. The Low preset averages 142 FPS. The Medium preset averages 110 FPS, with a minimum of 94 FPS and a maximum of 127 FPS. The High preset averages 83 FPS, and the Ultra preset drops to 79 FPS. The difference between Low and Ultra at 1440p is 63 FPS, which is less than at 1080p, showing that the GPU is becoming more constrained.

At 3840x2160, the system’s performance is at its lowest. The Low preset averages 105 FPS. The Medium preset averages 81 FPS, with a minimum of 69 FPS and a maximum of 94 FPS. The High preset averages 61 FPS, and the Ultra preset yields 58 FPS. The difference between Low and Ultra at 4K is 47 FPS, which is the smallest gap across all resolutions. This narrowing gap indicates that the GPU is nearing its limits, and the settings have less impact on the final frame rate because the resolution is the dominant factor.

The Medium preset is the only one with min/max data across all resolutions. At 1080p, the frame rate ranges from 116 to 157 FPS, a 41 FPS spread. At 1440p, the range is 94 to 127 FPS, a 33 FPS spread. At 4K, the range is 69 to 94 FPS, a 25 FPS spread. This decreasing variance as resolution increases further supports the conclusion that the GPU is the primary bottleneck, as there is less fluctuation when it is fully saturated.

Settings Recommendations

The measured data provides a clear hierarchy for settings presets at each resolution. For users prioritizing a smooth experience, the Low preset at 1080p offers the highest frame rate at 176 FPS, but this is likely excessive for a flight simulator where reaction times are less critical than in fast-paced genres. The Medium preset at 1080p provides a more balanced experience, with an average of 137 FPS and a minimum of 116 FPS, ensuring no significant drops below the refresh rate of most monitors.

At 1440p, the Medium preset is the recommended choice for a balanced experience. The 110 FPS average, with a minimum of 94 FPS, ensures smooth gameplay while providing a significant visual upgrade over Low settings. The High preset at 1440p drops to 83 FPS, which is still playable but offers diminishing returns over Medium. The Ultra preset at 1440p, at 79 FPS, is close to High in performance, but the visual difference may not justify the lower frame rate.

For 4K, the choice is more constrained. The Low preset at 105 FPS is the only option that provides a high refresh rate experience. The Medium preset at 81 FPS is a solid choice for a playable experience with better visuals, and its minimum of 69 FPS indicates it remains mostly stable. The High preset at 61 FPS and Ultra at 58 FPS are at the edge of playability, and the data suggests that the visual improvements from High to Ultra are not worth the 3 FPS difference. The Medium preset at 4K appears to be the sweet spot, offering a 81 FPS average with a reasonable minimum, balancing fidelity and smoothness.
