Microsoft Flight Simulator

The AMD Ryzen 7 5700 and NVIDIA GeForce GTX 1070 combination delivers a playable, though not consistently smooth, experience in Microsoft Flight Simulator, with the GPU acting as the primary bottleneck at higher resolutions and the CPU holding its own at lower settings. The data shows this pairing ranks in the bottom 15% of tested combos, but specific settings and resolution choices can dramatically alter the outcome, from a nearly unplayable 27.1 FPS at 4K Ultra to a fluid 79.6 FPS at 1080p Low.

Resolution Scaling

The measured FPS data reveals a steep performance cliff as resolution increases, clearly identifying the graphics card as the limiting factor in this configuration. Moving from 1920x1080 to 2560x1440 at High settings drops the average frame rate from 48.4 FPS to 38.7 FPS, a reduction of nearly 20%. The jump to 3840x2160 at High is even more punishing, with the average falling to 27.1 FPS—a 44% loss compared to 1080p High. This scaling pattern is typical of a GPU-bound scenario, where the number of pixels being rendered overwhelms the processing power of the GTX 1070.

At Low settings, the resolution scaling is less severe in absolute terms but still significant. The 1080p Low result of 79.6 FPS drops to 66.5 FPS at 1440p and further to 49.6 FPS at 4K. The fact that 4K Low still manages nearly 50 FPS while 4K High drops to 27.1 FPS indicates that the game’s visual quality presets have a massive impact on the GPU workload. The gap between 1440p High (38.7 FPS) and 1080p High (48.4 FPS) suggests that even modest resolution increases push this GPU to its limits, and the 4K results confirm that this combination is not suited for high-fidelity rendering at that resolution.

GPU Role

The NVIDIA GeForce GTX 1070, built on the Pascal architecture with a 16 nm process, is the clear performance limiter in this pairing. Its 8 GB of GDDR5 memory on a 256-bit bus provides 256.3 GB/s of bandwidth, which is adequate for 1080p but becomes strained at higher resolutions where texture data and frame buffers demand more capacity and throughput. The GPU’s boost clock of 1683 MHz and base clock of 1506 MHz are modest by modern standards, and its 6.463 TFLOPS of FP32 compute is reflected in the benchmark scores: the card sits in the 51st percentile of all GPUs, with a PassMark G3D score of 13498.

The benchmark results show the GTX 1070’s position relative to its nearest rivals. It is 0.7% ahead of the NVIDIA Quadro K4200 but 1.3% behind the GeForce GTX 880M and 1.4% behind the GeForce GTX 1650 SUPER in average benchmark score. This marginal separation underscores that the GTX 1070 is a mid-range performer by current standards, and in Microsoft Flight Simulator, the data confirms this: at 4K Ultra, the average FPS is identical to 4K High at 27.1 FPS, suggesting that the GPU hits a hard performance ceiling regardless of the quality preset. The transition from Low to Medium at 1080p shows a drop from 79.6 FPS to 66.8 FPS, while Medium to High only drops further to 48.4 FPS, indicating that the GPU’s shading units and texture units—1920 and 120 respectively—are saturated by the game’s complex scenery rendering.

CPU Role

The AMD Ryzen 7 5700 provides a solid foundation that does not bottleneck the GTX 1070 in most scenarios. With 8 cores and 16 threads based on the Zen 3 architecture, this CPU offers strong multi-threaded performance, as evidenced by its Cinebench R23 multi-core score of 20655 and single-core score of 2916. The processor’s boost clock of 4.60 GHz ensures that single-threaded tasks, which are common in flight simulation physics and flight model calculations, are handled efficiently. The CPU sits in the 84th percentile of all CPUs, with an average benchmark score of 27220, placing it just 0.7% ahead of the Intel Core i9-9900K and 0.8% ahead of the Intel Core i7-12700H.

The data suggests that the CPU is not the primary limiter in this game. At 1080p Low, the system achieves 79.6 FPS, which is a strong result that would likely be higher if the GPU were more capable. The fact that 1080p Ultra drops to 43.9 FPS while 1080p Low hits 79.6 FPS indicates that the GPU is responsible for the frame rate variance across settings. However, the CPU’s 16 MB of L3 cache and 51.2 GB/s memory bandwidth are sufficient for the game’s streaming world data, and the 3.70 GHz base clock ensures consistent performance even under sustained loads. The Ryzen 7 5700’s 65W TDP also means it runs cool, allowing the GPU to operate without thermal constraints from the CPU cooler.

How This Combo Ranks

In the database of tested combinations, this pairing of the Ryzen 7 5700 and GTX 1070 ranks 1532 out of 1795 combos for Microsoft Flight Simulator. This places it in the bottom 15% of all tested systems, which is a poor standing overall. The rank reflects the GPU’s age and mid-range status more than the CPU’s capability, as the Ryzen 7 5700 is a strong processor on its own. The combination’s low rank is driven by the fact that many other tested combos pair newer or higher-tier GPUs with similar CPUs, yielding much higher frame rates in this demanding title.

Despite the low overall rank, the combination is not without merit. The 1080p Low result of 79.6 FPS would likely outrank many combinations that include weaker CPUs but similar or better GPUs, as the CPU’s strong single-thread performance prevents it from dragging down the frame rate. The rank of 1532 also means that there are 263 tested combos that perform worse, which includes systems with older GPUs or significantly weaker processors. For a user with a 1080p monitor, this combination can deliver a playable experience, but for 1440p or 4K, the rank is justified by the sub-40 FPS results at higher settings.

FAQ

Q: Is this combination capable of running Microsoft Flight Simulator at 4K?

A: The data shows 4K performance is generally poor. At 4K Low, the average FPS is 49.6, but at 4K Medium it drops to 36, and at 4K High or Ultra it falls to 27.1. This indicates that 4K is only playable at Low settings, and even then with occasional dips.

A: At 2560x1440 High, the average FPS is 38.7, while at 3840x2160 High it is 27.1. The 4K resolution results in a 30% lower frame rate compared to 1440p.

Q: What is the GPU’s memory configuration and how does it affect performance?

A: The GTX 1070 has 8 GB of GDDR5 memory on a 256-bit bus with 256.3 GB/s bandwidth. The data shows that at 4K, performance drops sharply, which is consistent with the memory capacity and bandwidth being insufficient for high-resolution textures and geometry.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution. For 1920x1080, the Medium preset at 66.8 FPS offers the best balance between visual quality and playability, as it is 38% faster than High (48.4 FPS) while providing a noticeably better image than Low (79.6 FPS). The Ultra preset at 43.9 FPS is too close to the 40 FPS threshold for comfort in a flight simulator where smooth panning is critical.

At 2560x1440, the Low preset at 66.5 FPS is the only option that guarantees a consistently smooth experience. Medium at 48.4 FPS is playable but may stutter in dense scenery, while High at 38.7 FPS and Ultra at 38.8 FPS are below the ideal playable range. For 3840x2160, only the Low preset at 49.6 FPS is recommended, as Medium at 36 FPS and High/Ultra at 27.1 FPS are too choppy for a satisfying experience. Users should prioritize the Low preset at 4K or consider dropping to 1440p for higher quality settings.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are as follows: Low settings produce 79.6 FPS, Medium produces 66.8 FPS, High produces 48.4 FPS, and Ultra produces 43.9 FPS. This shows a clear progression of decreasing performance with increasing quality, with the largest single drop occurring between Medium and High (a 27.6% reduction).

The 2560x1440 results show a similar trend but with lower overall numbers: Low yields 66.5 FPS, Medium yields 48.4 FPS, High yields 38.7 FPS, and Ultra yields 38.8 FPS. Notably, Ultra is marginally faster than High at this resolution, which is within measurement variance. The gap between Low and Medium is 27.2%, while the gap between Medium and High is 20%—both significant reductions.

At 3840x2160, the performance is severely limited: Low produces 49.6 FPS, Medium produces 36 FPS, and both High and Ultra produce 27.1 FPS. The identical results for High and Ultra at 4K indicate that the GPU is completely saturated, and further quality increases do not affect the frame rate because the hardware cannot render more pixels per second. The overall pattern across all resolutions confirms that the GTX 1070 is the dominant constraint, with the CPU providing sufficient headroom to avoid being a secondary bottleneck.
