Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the AMD Ryzen 7 5700X and NVIDIA GeForce GTX 1070 reveal a steep and consistent performance drop as resolution climbs from 1920x1080 to 3840x2160. At Low settings, the average FPS falls from 84.4 at 1080p to 67 at 1440p, and then to 46.3 at 4K. That is a 45% reduction from 1080p to 4K, indicating that the rendering load scales heavily with pixel count, which is typical for a simulator that draws dense terrain and cockpit geometry.

The scaling pattern becomes more pronounced at higher quality presets. At High settings, the averages are 49.5 FPS at 1080p, 39.9 FPS at 1440p, and 30.4 FPS at 4K. At Ultra, the numbers are 47, 36.1, and 29.5 respectively. Notably, the gap between High and Ultra at 4K is only 0.9 FPS, while at 1080p the gap is 2.5 FPS. This suggests that at 4K, the system is rapidly approaching a hard performance ceiling where additional visual fidelity yields diminishing returns, because the GPU is saturated regardless of preset.

The data shows that the GTX 1070 becomes the limiting component well before 4K. At 1440p Medium, the average is 48.9 FPS, which is playable but not smooth. At 4K, even Low settings only manage 46.3 FPS, and every preset above Low drops below 40 FPS. The scaling from Low to Ultra at 4K is just 16.8 FPS, whereas at 1080p the same preset range spans 37.4 FPS. This compression of performance at higher resolutions is a clear indicator that the GPU's pixel throughput and memory bandwidth are the bottlenecks, not the CPU or the game's simulation logic.

The implication for users is straightforward: 1080p is the only resolution where this combo can deliver consistently high frame rates, and even then only at Low and Medium presets. At 1440p, the system is best suited for Low settings if aiming for 60 FPS or above. At 4K, the experience is constrained to the low-to-mid 40s at best, which is marginal for a flight simulator where smooth camera panning matters.

GPU Role

The NVIDIA GeForce GTX 1070 is a Pascal-architecture card with 8 GB of GDDR5 memory on a 256-bit bus, delivering 256.3 GB/s of bandwidth. Its base clock is 1506 MHz with a boost of 1683 MHz. These specifications place it in the 51st percentile of all GPUs in the benchmark database, with an average benchmark score of 12331. The nearest rivals are the NVIDIA Quadro K4200 (0.7% faster), the NVIDIA GeForce GTX 880M (1.3% slower), the NVIDIA GeForce GTX 1650 SUPER (1.4% slower), and the NVIDIA Tesla K20Xm (1.7% slower). This puts the GTX 1070 in a tightly contested mid-range segment.

In Microsoft Flight Simulator, the GTX 1070's 8 GB VRAM is adequate for 1080p and 1440p at all tested presets, as the measured FPS does not collapse due to memory exhaustion. However, at 4K, the combination of higher resolution textures and denser geometry pushes the card to its limits. The memory bandwidth of 256.3 GB/s appears to be a critical constraint: at 4K Ultra, the average FPS drops to 29.5, which is below the threshold for comfortable play. The FP32 throughput of 6.463 TFLOPS is modest by modern standards, and the data reflects this in the steep scaling curve.

The GPU's role is further clarified by comparing Low and Ultra at each resolution. At 1080p, the difference is 37.4 FPS, meaning the GPU has headroom to render extra effects. At 1440p, the difference narrows to 30.9 FPS. At 4K, it shrinks to 16.8 FPS. This pattern shows that as pixel count rises, the GPU's fixed resources—shading units, ROPs, and memory bandwidth—become fully utilized, leaving less room for preset-driven performance variation. The card is simply not built for 4K flight simulation, and the benchmark results confirm that expectation.

Measured FPS Breakdown

At 3840x2160, the measured averages are: Low 46.3 FPS, Medium 38.2 FPS, High 30.4 FPS, and Ultra 29.5 FPS. The range from best to worst preset is 16.8 FPS, which is the smallest spread of any resolution. This indicates that at 4K, the GPU is the dominant constraint, and preset changes have limited impact on the final frame rate. The step from Medium to High costs 7.8 FPS, while the step from High to Ultra costs only 0.9 FPS, showing diminishing returns at the top end.

At 2560x1440, the averages improve significantly: Low 67 FPS, Medium 48.9 FPS, High 39.9 FPS, and Ultra 36.1 FPS. The spread expands to 30.9 FPS, giving users more meaningful choices. Low settings are the only preset that clears 60 FPS, while Medium is close at 48.9 FPS. The gap between High and Ultra is 3.8 FPS, which is noticeable but modest. This resolution offers a better balance between visual quality and performance than 4K.

At 1920x1080, the averages are: Low 84.4 FPS, Medium 61.3 FPS, High 49.5 FPS, and Ultra 47 FPS. This is the only resolution where all presets are above 45 FPS, and Low is comfortably above 60 FPS. The spread of 37.4 FPS is the largest, meaning the GPU has enough headroom to respond to preset changes. The difference between High and Ultra is only 2.5 FPS, so High is the more efficient choice for nearly identical visual quality. The data clearly shows that 1080p is the intended operating resolution for this hardware combination.

CPU Role

The AMD Ryzen 7 5700X is a Zen 3 (Vermeer) processor with 8 cores and 16 threads, running at a base clock of 3.40 GHz and a boost of 4.60 GHz. It has 32 MB of shared L3 cache and supports DDR4 memory with a dual-channel bus. Its average benchmark score is 26214, placing it in the 83rd percentile of all CPUs. The nearest rivals are the Intel Core i9-11900KF (0.1% faster), the AMD Ryzen 7 PRO 6850U (0.2% slower), the AMD Ryzen 5 5500GT (0.2% faster), and the AMD Ryzen 5 7600X (0.2% slower). This places the 5700X in a highly competitive performance band.

In Microsoft Flight Simulator, the CPU's role is to handle the simulation logic, including flight physics, weather, and AI traffic, while the GPU renders the scene. The measured FPS data shows that at 1080p Low, the system reaches 84.4 FPS, which is a strong result. This suggests the 5700X's 8 cores and 16 threads are sufficient to keep the GTX 1070 fed at lower resolutions. The CPU's single-thread performance, reflected in a Cinebench R23 single-core score of 3193, is also important for a game that relies on a main simulation thread.

However, the data also indicates that the CPU is not the primary bottleneck in this configuration. At 4K, performance drops to the low 30s regardless of preset, which points to the GPU being the limiting factor. If the CPU were the constraint, we would expect less variation in FPS across resolutions. Instead, the scaling pattern from 1080p to 4K is consistent with a GPU-bound scenario. The 5700X's boost clock of 4.60 GHz and 32 MB of L3 cache provide ample headroom for this title, and the measured results confirm that the CPU is not holding back the system in most scenarios.

Settings Recommendations

The measured data suggests that for a smooth experience, users should prioritize resolution over preset quality. At 1920x1080, the Low preset delivers 84.4 FPS, which is ideal for high-refresh-rate displays, while Medium at 61.3 FPS is also excellent and offers better visual fidelity. High at 49.5 FPS is borderline for 60 Hz displays, and Ultra at 47 FPS adds little over High for a 2.5 FPS cost. The best experience at 1080p is Medium, as it balances visual detail with a frame rate that is well above 60 FPS.

At 2560x1440, the choices are more constrained. Low at 67 FPS is the only preset that comfortably exceeds 60 FPS, making it the recommended setting for competitive or smooth gameplay. Medium at 48.9 FPS is playable but below the 60 FPS threshold, and High at 39.9 FPS or Ultra at 36.1 FPS are only suitable for users who prioritize visuals over fluidity. For most users, Low at 1440p is the best compromise, as it provides a high-resolution image without sacrificing frame rate.

At 3840x2160, no preset achieves 60 FPS. Low at 46.3 FPS is the best possible result, followed by Medium at 38.2 FPS. High and Ultra at 30.4 and 29.5 FPS respectively are below the 30 FPS threshold that many consider the minimum for playable flight simulation. For 4K users, Low is the only sensible choice, and even then, the experience will be noticeably less smooth than at lower resolutions. The data strongly suggests that this hardware combo is not suited for 4K gaming, and users should stick to 1080p or 1440p for the best experience.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700X and NVIDIA GeForce GTX 1070 ranks 1518 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the bottom 15% of all tested systems, which is a low position for a CPU that ranks in the 83rd percentile globally. The discrepancy highlights the GPU's role as the limiting factor. The GTX 1070, with an average benchmark score of 12331 and a 51st percentile ranking, is the weaker component in this pairing.

The measured FPS data confirms this ranking. At 1080p, the system achieves a maximum of 84.4 FPS, which is respectable, but many modern GPUs would deliver far higher numbers. At 4K, the system struggles to maintain 30 FPS on most presets, which is below the standard for contemporary gaming. The combo's rank of 1518 suggests that users with this setup will need to make significant compromises in resolution or settings to achieve a playable experience.

In comparison to other combos, the CPU's nearest rivals (such as the Intel Core i9-11900KF) are within 0.2% in average CPU score, so the processor is not the differentiator. The GPU's nearest rivals (like the GTX 1650 SUPER) are within 1.4% in GPU score, indicating that the GTX 1070 is competitive with its immediate peers. The low combo rank is therefore a reflection of the GPU's age and capability relative to newer hardware, rather than a deficiency in the CPU. Users seeking better performance in this game would need to upgrade the GPU, as the CPU has ample headroom.
