Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and this particular pairing of the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4070 shows a system that is well-balanced, though with clear performance ceilings depending on how you configure it. The data indicates this combo is capable of excellent frame rates at 1080p and 1440p, but 4K gaming will require some settings compromises to maintain smoothness. This analysis breaks down the measured performance across resolutions and presets, interpreting what the numbers mean for your flight planning.

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

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor built on the Zen 3 architecture with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. Its defining feature is the 96 MB of shared L3 cache, which is a massive amount for a desktop chip and is specifically designed to feed simulation-heavy workloads that often rely on large datasets. This cache advantage helps explain why this CPU performs strongly in this game, where physics, weather, and AI traffic calculations can create significant single-thread and multi-thread demands.

In the broader benchmark landscape, this CPU sits at the 83rd percentile among all processors, with an average benchmark score of 26574. The nearest rivals show a tight cluster of performance: it is effectively even with the AMD EPYC 8024P and Intel Core i9-11900K, each showing a deltaPct of 0.1. It trails the AMD Ryzen 5 7600 by a negligible 0.2 percent and the Intel Core i9-12900HK by 0.4 percent. This indicates that the 5800X3D is not the absolute fastest CPU available, but it is right at the top of its performance tier, and its large cache is likely a key reason it holds its own against newer architectures in a game that benefits from data locality.

The measured FPS data shows that at 1080p with Low settings, the system hits 166.2 FPS, which is the highest average in the entire dataset. This high frame rate at a low graphical load suggests that the CPU is capable of pushing the game engine to very high frame rates when the GPU is not the bottleneck. The fact that this number is so much higher than the 4K Low result of 93.6 FPS indicates that the CPU is not the limiting factor at lower resolutions; rather, the GPU takes over as the primary constraint as resolution and detail increase. The CPU’s 105 W TDP and socket AM4 compatibility make it a practical upgrade for many existing systems, but its role here is clearly to keep the simulation logic running fast enough to never starve the GPU.

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

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture and features 12 GB of GDDR6X memory on a 192-bit bus, providing a memory bandwidth of 504.2 GB/s. The GPU has a base clock of 1920 MHz and a boost clock of 2475 MHz, with memory running at an effective 21 Gbps. In terms of overall GPU performance, it sits at the 81st percentile among all graphics cards, with an average benchmark score of 37283.

The nearest rivals for the RTX 4070 show some unusual comparisons. It is 0.6 percent slower than the AMD Radeon RX Vega 56, and 1.9 percent slower than the NVIDIA GeForce MX570 A, which are both older or lower-tier cards in the benchmark aggregate. However, it is 2.2 percent slower than the NVIDIA GeForce RTX 4080 Mobile and 2.5 percent faster than the AMD Radeon RX 5300M. These deltaPct values are based on synthetic benchmark averages, which do not always translate directly to gaming performance. The RTX 4070's 12 GB of VRAM is a solid amount for this title, as Flight Simulator can be memory-hungry with high-resolution textures.

The measured FPS data shows the GPU's influence clearly. At 1080p with Ultra settings, the system produces 91.3 FPS, which is a strong result. But the more telling numbers come from the 4K results: at 4K Ultra, the average FPS drops to 55.7, and at 4K High it is 54.4. This significant drop from 1080p to 4K indicates that the GPU is the primary bottleneck at higher resolutions. The GPU's 158.4 GPixel/s pixel rate and 455.4 GTexel/s texture rate are being taxed heavily at 4K, and the 12 GB VRAM is likely being filled with high-resolution terrain and aircraft textures. The data suggests that for a smooth 4K experience, you will need to lower the settings, as the GPU cannot maintain 60 FPS at High or Ultra presets at that resolution.

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

The scaling of frame rates across resolutions tells a clear story about which component is the limiting factor in this system. At 1080p, the performance is excellent across all presets, with Low hitting 166.2 FPS, Medium at 128.3 FPS, High at 95 FPS, and Ultra at 91.3 FPS. Moving to 1440p, the frame rates drop, but remain very playable: Low at 133.8 FPS, Medium at 100.7 FPS, High at 77.4 FPS, and Ultra at 74.9 FPS. At 4K, the drop becomes much more pronounced: Low at 93.6 FPS, Medium at 72.6 FPS, High at 54.4 FPS, and Ultra at 55.7 FPS.

The pattern here is that the percentage drop from 1080p to 4K is much larger than the drop from 1080p to 1440p. For example, at High settings, the FPS drops from 95 at 1080p to 77.4 at 1440p (a roughly 18.5 percent decrease), but then drops to 54.4 at 4K (a roughly 42.7 percent decrease from 1440p). This accelerating decline is the classic signature of a GPU bottleneck. The CPU has enough headroom to feed the GPU at 1080p, but as the resolution increases, the GPU has to work much harder on pixel shading and texture mapping, and the frame rate falls accordingly.

The interesting anomaly is the 4K Ultra vs. 4K High result. Ultra produces 55.7 FPS, which is slightly higher than High's 54.4 FPS. This is likely within the margin of measurement error or could be due to specific in-game scenes, but it suggests that the Ultra preset does not add a significant additional GPU load over High in this test. Overall, the data indicates that this system is ideal for 1080p and 1440p gaming, where it can deliver high frame rates, but 4K will require turning down settings to maintain smoothness. The limiting component at 4K is clearly the GPU, as the CPU’s performance is consistent enough to support the lower frame rates without causing a further drop.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience depends heavily on your target resolution and refresh rate. For 1080p users with a high-refresh monitor, the High preset at 95 FPS is an excellent choice, offering a strong balance between visual fidelity and smoothness. The Ultra preset at 91.3 FPS is also viable, but the marginal visual gain over High may not justify the 3.7 FPS drop. For those with a 144Hz monitor, the Medium preset at 128.3 FPS is the sweet spot, as it provides a substantial frame rate boost over High while still looking decent. The Low preset at 166.2 FPS is only recommended for competitive or minimal-crash scenarios, as it likely sacrifices too much visual detail for the extra frames.

At 1440p, the High preset at 77.4 FPS is a solid recommendation for a smooth experience on a 60Hz or 75Hz monitor, and it is only slightly behind Ultra at 74.9 FPS. The Medium preset at 100.7 FPS is ideal for higher refresh rate 1440p displays, as it provides a very fluid experience without the visual degradation of Low. For 4K, the situation is tighter. The Ultra preset at 55.7 FPS is technically playable but falls short of the 60 FPS target. The Medium preset at 72.6 FPS is the best recommendation for 4K, as it provides a more comfortable frame rate cushion above 60 FPS while still retaining a reasonable level of detail. The High preset at 54.4 FPS is not recommended, as it offers no advantage over Ultra and is below the Medium preset's performance.

In summary, the data suggests that the High preset is the best all-around choice for 1080p and 1440p, while the Medium preset is the most sensible option for 4K. The Ultra preset is only worth using at 1080p, where the performance penalty is minimal. The Low preset is a fallback for maximum frame rates, but the measured numbers show that it is rarely necessary for a good experience on this hardware.
