Microsoft Flight Simulator

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

The AMD Ryzen 9 5900X brings substantial processing resources to Microsoft Flight Simulator. With 12 cores and 24 threads from the Zen 3 architecture, this CPU belongs to the 5000 series and operates on the AM4 socket. The base clock of 3.70 GHz and boost clock of 4.80 GHz provide the single-thread headroom that flight simulators demand, while the 64 MB of L3 cache helps keep terrain and aircraft data close to the cores. The 7 nm process node from TSMC, with 8,300 million transistors across a dual-die design, supports a 105 W TDP.

Benchmark results confirm this CPU's balanced profile. In Cinebench R23, the multicore score of 33150 and single-core score of 4680 indicate strong performance across both heavily threaded and lightly threaded workloads. The Geekbench multicore score of 11877 and single-core score of 2202 align with this pattern. In PassMark, the multithread score of 39002 and single-thread score of 3469 show consistent capability. The 3DMark results are telling: 16-thread score of 9075, 8-thread score of 6601, 4-thread score of 3588, and 2-thread score of 1852. This scaling curve suggests that Microsoft Flight Simulator can effectively use additional cores, but the game's frame pacing depends heavily on strong per-core performance.

The CPU's 90th percentile ranking among all tested processors places it firmly in the upper tier. Its nearest rivals include the AMD EPYC 4245P with an average score of 39383 (0.2% lower), the AMD Ryzen 7 PRO 8845HS at 39747 (0.7% higher), the Intel Core i7-13700F at 39095 (0.9% lower), and the Intel Core i7-13700 at 39857 (1% higher). The Ryzen 9 5900X sits essentially at parity with these alternatives, meaning any frame rate differences in this game come from other system components or the game's engine behavior rather than CPU throughput.

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

The measured data reveals a clear pattern across all three resolutions: the Low preset consistently delivers the highest average frame rates, while the Ultra preset produces the lowest. At 1920x1080, Low achieves 99.2 FPS, Medium reaches 78.1 FPS, High drops to 56.8 FPS, and Ultra bottoms out at 54.9 FPS. The gap between Low and Medium is 21.1 FPS, while the gap between Medium and High is another 21.3 FPS. The High-to-Ultra step is comparatively small at 1.9 FPS, suggesting diminishing returns as settings approach maximum.

At 2560x1440, the same ordering holds: Low at 81.9 FPS, Medium at 65.2 FPS, High at 46.9 FPS, and Ultra at 45.5 FPS. The Low-to-Medium delta narrows to 16.7 FPS, and the Medium-to-High drop is 18.3 FPS. The High-to-Ultra difference remains modest at 1.4 FPS. At 3840x2160, Low produces 58.2 FPS, Medium 46.7 FPS, High 33.2 FPS, and Ultra 34.0 FPS. Interestingly, Ultra actually outperforms High slightly at 4K by 0.8 FPS, though both are below the 60 FPS threshold.

For a smooth experience, the Low preset is the only option that consistently exceeds 60 FPS across all resolutions, with 99.2 FPS at 1080p and 58.2 FPS at 4K. The Medium preset stays playable at 1080p and 1440p but falls below 60 FPS at 4K. The data suggests that High and Ultra presets are best reserved for users who prioritize visual fidelity over frame rate, as they hover in the 33-57 FPS range depending on resolution. Given that flight simulation often benefits from stable frame pacing, the Medium preset appears to offer a reasonable balance—still above 46 FPS in all cases—but the Low preset is the only configuration that guarantees comfortable frame rates throughout.

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

The frame rate scaling across resolutions points directly at the GPU as the primary bottleneck in this configuration. Moving from 1920x1080 to 2560x1440 at Low settings, the average FPS drops from 99.2 to 81.9, a reduction of 17.4%. Continuing to 3840x2160 at Low brings the average down to 58.2, which is 41.3% below the 1080p figure. This consistent degradation with resolution suggests the Radeon RX 7600's rendering throughput is the limiting factor.

At Medium settings, the drop from 1080p (78.1 FPS) to 1440p (65.2 FPS) is 16.5%, and the further drop to 4K (46.7 FPS) represents a 40.2% loss from the 1080p baseline. The High preset shows a similar trajectory: 56.8 FPS at 1080p, 46.9 FPS at 1440p (17.4% lower), and 33.2 FPS at 4K (41.5% lower). The Ultra preset follows the same pattern, going from 54.9 FPS at 1080p to 45.5 FPS at 1440p (17.1% lower) and then to 34.0 FPS at 4K (38.1% lower).

The proportional consistency of these drops—roughly 17% from 1080p to 1440p and another 24% from 1440p to 4K—indicates that the CPU is not becoming a bottleneck at lower resolutions. If the Ryzen 9 5900X were limiting performance, the 1080p numbers would be much closer together across settings, and the resolution scaling would flatten out. Instead, the steady decline with pixel count shows that the RX 7600's 8 GB frame buffer and 288.0 GB/s memory bandwidth are being saturated as resolution increases. The 128-bit memory bus and 18 Gbps effective memory clock are adequate for 1080p but struggle to maintain frame rates when pixel throughput demands double or quadruple.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 9 5900X and AMD Radeon RX 7600 ranks 1290th out of 1795 tested combos in Microsoft Flight Simulator. That places this configuration in the 28th percentile of all tested systems, meaning roughly 72% of tested combinations deliver higher average frame rates. This ranking is notably lower than the individual component percentiles would suggest—the CPU sits at the 90th percentile and the GPU at the 63rd percentile—which implies that the pairing itself may not be ideal for this particular game.

The ranking gap likely stems from the game's sensitivity to GPU performance relative to CPU capability. In Microsoft Flight Simulator, the 12-core Ryzen 9 5900X provides far more processing headroom than the RX 7600 can utilize. The GPU's 63rd percentile standing, combined with its 8 GB VRAM, creates a situation where the CPU is waiting on the GPU in most scenarios. The measured frame rates, which top out at 99.2 FPS at 1080p Low, reflect this imbalance. Systems with more balanced CPU-GPU pairings, or those with stronger GPUs, would rank higher despite having less capable processors.

The data shows that this combo produces playable results at 1080p and 1440p when settings are kept at Low or Medium, but the overall ranking suggests that users with this hardware should be prepared for compromises. The proximity of the CPU's nearest rivals—all within 1% of its average benchmark score—indicates that swapping to any of those processors would not meaningfully change the frame rates. The bottleneck is firmly on the GPU side, as confirmed by the measured FPS breakdown.

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

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with the Navi 33 chip, manufactured on a 6 nm process from TSMC with 13,300 million transistors. Its 8 GB of GDDR6 memory on a 128-bit bus provides 288.0 GB/s of bandwidth, which the game's asset streaming clearly taxes. The boost clock of 2655 MHz and game clock of 2250 MHz, with a base clock of 1720 MHz, deliver a peak FP32 throughput of 21.75 TFLOPS. The 2048 shading units, 128 TMUs, and 64 ROPs process geometry and textures, while 32 ray accelerators handle any ray-traced effects.

The GPU's 63rd percentile ranking among all tested graphics cards places it in the mid-range tier. Its nearest rivals include the Radeon RX 7600 XT with an average score of 20146 (0.6% higher), the Radeon RX 460 at 20088 (0.8% higher), the GeForce RTX 3070 Mobile at 20534 (1.3% lower), and the Intel Arc B570 at 20556 (1.5% lower). The tight clustering of these scores—all within 2.3% of each other—means that the RX 7600's performance is representative of its class, and the measured frame rates reflect this mid-pack standing.

In Microsoft Flight Simulator, the GPU's role is evident from the resolution scaling data. At 1080p, the card can push frame rates above 90 FPS when settings are lowered, but at 4K, even the Low preset only manages 58.2 FPS. The 8 GB VRAM and 288.0 GB/s bandwidth are likely strained when the game loads high-resolution terrain textures and detailed aircraft models. The 128-bit memory bus limits simultaneous data transfer, which becomes more critical as pixel count increases. The 165 W TDP and single 8-pin power connector indicate this is a power-efficient card, but that efficiency does not translate into the raw throughput needed for high-fidelity flight simulation at 4K.

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

The complete measured frame rate data reveals how this combo performs across every tested configuration. At 1920x1080, the Low preset delivers 99.2 FPS, making it the only setting that approaches triple-digit performance. Medium follows at 78.1 FPS, which is a 21.3% reduction. High drops further to 56.8 FPS, a 27.3% reduction from Medium. Ultra comes in at 54.9 FPS, just 3.3% below High. This pattern suggests that the High-to-Ultra transition adds minimal visual benefit relative to its modest frame rate cost.

At 2560x1440, the frame rates compress slightly. Low achieves 81.9 FPS, which is 17.5% lower than the 1080p Low result. Medium reaches 65.2 FPS, a 20.4% drop from 1440p Low. High produces 46.9 FPS, a 28.1% reduction from Medium. Ultra sits at 45.5 FPS, just 3.0% below High. The 1440p results show that the GPU begins to struggle more noticeably, with the gap between Low and the higher presets widening compared to 1080p.

At 3840x2160, the limits of this hardware become apparent. Low yields 58.2 FPS, which is 29.0% lower than the 1440p Low result. Medium falls to 46.7 FPS, a 19.8% drop from Low. High drops to 33.2 FPS, a 28.9% reduction from Medium. Ultra records 34.0 FPS, which is actually 2.4% higher than High—a slight anomaly in the data that may reflect variable scene complexity. The 4K results show that only the Low preset remains near playable thresholds, while High and Ultra dip below 35 FPS, which would be noticeable in a flight simulation context where smooth camera panning is essential.

Across all resolutions, the data shows a consistent hierarchy: Low > Medium > High ≈ Ultra. The High and Ultra presets are nearly interchangeable in performance, with differences of less than 2 FPS at every resolution. This suggests that the game's Ultra preset may not add significantly more rendering work than High, or that the GPU is already saturated at High and cannot render Ultra at a lower frame rate. The measured numbers provide a clear guide: for 60+ FPS, use Low at any resolution; for 50+ FPS, use Medium at 1080p or Low at 1440p; for 4K, only Low is viable.
