Microsoft Flight Simulator

The AMD Ryzen 7 7700 and AMD Radeon RX 7900 XTX pairing delivers a fascinating dataset in Microsoft Flight Simulator, revealing a configuration that is heavily influenced by resolution and settings. The measured frames per second (FPS) across the board indicate a system capable of high refresh rates at 1080p, but one that requires careful tuning to maintain smoothness at 4K. This analysis breaks down the measured results to understand the balance between the CPU and GPU in this specific flight sim.

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

The data shows a classic resolution scaling curve, but with some interesting nuances. At 1080p with Low settings, the combo achieves an average of 192.2 FPS. Moving to 1440p drops that to 151.9 FPS, a reduction of about 21%. At 4K, the average falls to 109.5 FPS, which is a 43% drop from 1440p and a 43% drop from 1080p. This scaling suggests that while the GPU is powerful, it is not the sole bottleneck at lower resolutions.

The picture changes dramatically when looking at the Ultra preset. At 1080p Ultra, the average is 108.8 FPS. At 1440p Ultra, it drops to 83.5 FPS, and at 4K Ultra, it falls to 63.9 FPS. The percentage drop from 1080p to 1440p is about 23%, and from 1440p to 4K is another 23%. This consistent scaling pattern across all resolutions on Ultra suggests that the GPU is becoming the primary limiting factor as the workload increases.

However, the Low preset tells a different story. The gap between 1080p Low (192.2 FPS) and 1440p Low (151.9 FPS) is a 21% drop, which is less than the 43% drop seen when moving to 4K. This indicates that at lower settings and resolutions, the CPU is likely the limiting component, holding back the frame rate. The fact that 1080p High (111.5 FPS) is nearly identical to 1080p Ultra (108.8 FPS) further suggests that the CPU is hitting a ceiling in this scenario, as the GPU has headroom to render higher settings without a significant FPS penalty.

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

The Radeon RX 7900 XTX is a high-end part with a 24 GB GDDR6 memory pool on a 384-bit bus, providing a bandwidth of 960.0 GB/s. This substantial memory allocation is crucial for a simulator like Microsoft Flight Simulator, which often loads large textures and terrain data. The 24 GB capacity means that even at 4K Ultra, VRAM is unlikely to be a limiting factor, as the data shows a playable 63.9 FPS average in that configuration.

The GPU's boost clock is listed at 2498 MHz, with a game clock of 2365 MHz. The architecture is RDNA 3.0 on a 5 nm process. The benchmark results for the GPU show a Passmark G3D score of 31238, placing it in the 85th percentile of all GPUs. Its nearest rivals in the database include the NVIDIA GeForce RTX 4090 Mobile (with a deltaPct of 0.8) and the NVIDIA GeForce RTX 4070 Ti (with a deltaPct of -2). This performance level is consistent with the measured FPS, which show the card handling 1440p High at 88.2 FPS and 4K Medium at 86.6 FPS.

The GPU's role becomes more pronounced at higher resolutions. At 4K, the FPS difference between Low (109.5) and Ultra (63.9) is a 42% gap, demonstrating that the GPU's compute and memory bandwidth are being heavily taxed. The fact that the 4K Ultra result (63.9 FPS) is nearly identical to the 4K High result (63.6 FPS) is telling—it implies that the Ultra preset does not cause a massive additional load over High, possibly due to a CPU bottleneck even at 4K, or that the settings between High and Ultra have diminishing returns on this GPU.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations for Microsoft Flight Simulator, this specific pairing of the Ryzen 7 7700 and RX 7900 XTX ranks at position 239 out of 1795 total combos. This places it in the top 13% of all tested systems. The rank is a composite measure, likely weighing the average FPS across all settings and resolutions. Given the high percentile scores of both components—the CPU is in the 91st percentile and the GPU is in the 85th percentile—a top-250 ranking seems consistent with their individual standings.

The interpretation of this rank is nuanced. While it is a strong position, it is not at the absolute top. This suggests that there are other combinations that achieve higher average frame rates. The data implies that the CPU, while strong, may not be the absolute best partner for this GPU in this specific title, as the GPU's potential is not fully unleashed at 1080p. The ranking also reflects that this is a high-end setup, as most of the 1795 combos will feature less powerful hardware. The deltaPct values for the CPU's rivals are all within 1.2% of its average score, indicating that the Ryzen 7 7700 is in a tightly contested performance tier.

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

The measured data provides a clear path for optimizing the experience. For 1080p users, the High preset yields 111.5 FPS, which is a solid target for a high refresh rate monitor. The Ultra preset at 108.8 FPS is nearly identical, so the visual gains of Ultra can be had for a negligible FPS cost. The Low preset at 192.2 FPS is only useful for competitive play or if the user has a 240Hz display, but it sacrifices significant visual fidelity.

At 1440p, the High preset at 88.2 FPS is the sweet spot for a smooth experience, as it sits above the 60 FPS threshold with headroom. The Ultra preset at 83.5 FPS is also playable, but the 5% drop from High might not be worth the extra visual load. The Medium preset at 116.6 FPS offers a good balance for those seeking higher frame rates without dropping to Low.

For 4K, the situation is more delicate. The High preset at 63.6 FPS is just above the playable threshold, but the Medium preset at 86.6 FPS provides a much more comfortable margin. The Ultra preset at 63.9 FPS is essentially identical to High, so there is no reason to choose High over Ultra at this resolution. The data suggests that Medium is the recommended preset for 4K, as it offers a 36% FPS improvement over Ultra while likely maintaining acceptable visual quality.

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

The AMD Ryzen 7 7700 is an 8-core, 16-thread processor based on the Zen 4 architecture, codenamed Raphael. It has a base clock of 3.80 GHz and a boost clock of 5.30 GHz. The CPU's benchmark scores are robust, including a Cinebench R23 multicore score of 29302 and a single-core score of 4136. Its Passmark single-thread score is 4063, and its multithread score is 34470. These figures indicate a strong processor for both lightly-threaded and heavily-threaded workloads.

In Microsoft Flight Simulator, the CPU's role is evident in the 1080p results. The FPS at 1080p High (111.5) and 1080p Ultra (108.8) are almost identical, despite the increased GPU load of the Ultra preset. This indicates that the CPU is the limiting factor at these settings, preventing the GPU from fully flexing its muscles. The 1080p Low result of 192.2 FPS shows the CPU's ceiling; it can push high frame rates when the GPU is not the bottleneck.

The CPU's 32 MB of shared L3 cache and support for DDR5 memory with a bandwidth of 83.2 GB/s likely help with the game's streaming of terrain data. The processor's percentile ranking of 91st among all CPUs, with an average benchmark score of 40468, places it slightly above its nearest rival, the AMD Ryzen 9 7940H, which has an average score of 40431 and a deltaPct of 0.1. This suggests that the 7700 is a top-tier CPU, and its limitations in this game are more about the game's engine than a lack of processing power.
