Microsoft Flight Simulator

# Microsoft Flight Simulator with AMD Ryzen 7 9850X3D + AMD Radeon RX 6600

This combination pairs AMD's flagship 9000-series 3D V-Cache processor with a mainstream RDNA 2 graphics card, creating a system that is heavily front-loaded on CPU capability. The measured data reveals a configuration that delivers playable but not spectacular frame rates across most settings, with the RX 6600 clearly acting as the primary constraint at higher resolutions. The combo ranks 2316th out of 2996 tested combinations in this game, placing it in the lower third of all tested systems, which suggests that while the CPU is among the top tier, the GPU holds the overall experience back significantly.

Resolution Scaling

The FPS drop from 1080p to 4K tells a clear story about where the bottleneck lives in this system. At Low settings, the average frame rate falls from 92 FPS at 1920x1080 to 74 FPS at 2560x1440, then to 55 FPS at 3840x2160. That represents a 40% reduction from 1080p to 4K, which is a relatively modest scaling curve for a flight simulator that is known to be demanding on both CPU and GPU.

When moving to High settings, the scaling becomes more aggressive. The system delivers 54 FPS at 1080p, drops to 43 FPS at 1440p, and falls to 32 FPS at 4K. That is a 41% loss from 1080p to 4K, but the absolute numbers are low enough that the GPU is clearly the limiting factor. The RX 6600's 8 GB of GDDR6 memory and 224.0 GB/s bandwidth are being stressed at higher resolutions, particularly with the more demanding visual presets.

The Medium preset shows a similar pattern: 72 FPS at 1080p, 58 FPS at 1440p, and 43 FPS at 4K. The Ultra preset is the most demanding, yielding 51 FPS at 1080p, 41 FPS at 1440p, and just 31 FPS at 4K. The consistent pattern across all four presets is that the gap between 1080p and 1440p is roughly 20-25%, while the gap between 1440p and 4K is another 25-30%. This suggests a GPU that is becoming progressively more saturated as resolution increases, with the CPU's substantial headroom unable to compensate.

The data implies that at 1080p, the system is still partially CPU-bound, as evidenced by the large jump from 54 FPS at High to 92 FPS at Low — a massive 70% improvement that would not occur if the GPU were the sole constraint. However, by 4K, the GPU is so heavily loaded that even dropping from High to Low only improves performance from 32 FPS to 55 FPS, a 72% gain that still falls short of smooth gameplay. This indicates that the RX 6600 is the dominant performance limiter at 4K regardless of settings.

Settings Recommendations

Examining the measured rows, the Medium preset offers the most balanced experience across all three resolutions. At 1080p, Medium delivers 72 FPS average with a minimum of 61 FPS and maximum of 82 FPS — this is the only preset at any resolution that maintains a minimum above 60 FPS. At 1440p, Medium produces 58 FPS average with a minimum of 49 FPS and maximum of 66 FPS, which is playable for a flight simulator where frame pacing is less critical than in fast-paced action games.

The High preset at 1080p delivers 54 FPS average, which is respectable but lacks the minimum frame data to confirm consistency. The Low preset at 1080p achieves 92 FPS, but this comes at a significant visual quality cost that undermines the immersive experience that flight simulators are known for. For users prioritizing smoothness over visual fidelity, Low at 1440p (74 FPS) or Low at 1080p (92 FPS) are the only options that exceed 60 FPS comfortably.

At 4K, none of the presets achieve 60 FPS. The best option is Low at 55 FPS, followed by Medium at 43 FPS, High at 32 FPS, and Ultra at 31 FPS. Given that the minimum FPS data is only available for Medium (36 FPS at 4K), users targeting 4K should be aware that even the most modest preset will struggle to maintain smooth performance. The data suggests that Medium at 1440p is the sweet spot for this combination, offering a 58 FPS average with known minimums of 49 FPS, which represents the best compromise between visual quality and playability.

For users who insist on 4K, the Medium preset at 43 FPS average with a 36 FPS minimum is the only option with measured minimum data, and it barely crosses the threshold of playability. The Ultra preset at 31 FPS is effectively a slideshow for a game that requires constant visual attention, and the High preset at 32 FPS is only marginally better. The Low preset at 55 FPS is the only 4K option that approaches playable territory, but it sacrifices the detailed scenery and lighting that make flight simulators compelling.

How This Combo Ranks

The combo rank of 2316 out of 2996 tested combinations places this system in the 77th percentile of all tested combos — meaning roughly 77% of all tested systems outperform it in Microsoft Flight Simulator. This is a surprisingly low ranking given the CPU's capabilities, and it directly reflects the GPU's limitations in this title. The RX 6600's percentileVsAllGpus of 63 indicates that it outperforms 63% of all GPUs in general benchmarks, but in this specific game, the combination with the Ryzen 7 9850X3D does not boost the overall experience.

The CPU itself ranks in the 92nd percentile vs all CPUs, with an average benchmark score of 58,386. Its nearest rivals include the Intel Xeon Platinum 8260M (avgScore 58,323, deltaPct 0.1), Intel Xeon w5-2545 (avgScore 58,504, deltaPct -0.2), Intel Core i9-14900 (avgScore 58,115, deltaPct 0.5), and AMD Ryzen AI 9 HX 470 (avgScore 58,826, deltaPct -0.7). The CPU's performance is within 1% of all these rivals, indicating that it is not the limiting factor in this game.

The GPU's nearest rivals tell a similar story. The RX 6600 (avgBenchmarkScore 19,036) is nearly identical to the NVIDIA Quadro K6000 (19,030, deltaPct 0), NVIDIA GeForce RTX 4050 Mobile (19,049, deltaPct -0.1), NVIDIA Tesla K20m (19,089, deltaPct -0.3), and NVIDIA RTX 2000 Ada Generation (18,954, deltaPct 0.4). The GPU's performance is essentially tied with these rivals, all of which are mid-range or older professional parts. This suggests that the GPU's general compute capability is adequate, but not exceptional, for this game's demands.

The ranking gap between the CPU's 92nd percentile and the combo's 77th percentile highlights a significant imbalance. This is a system where the processor is capable of far more than the graphics card can deliver, and Microsoft Flight Simulator's heavy reliance on GPU resources for terrain rendering and lighting calculations means the CPU's strengths are largely underutilized in this specific workload.

Measured FPS Breakdown

The complete measured FPS data reveals a consistent hierarchy across resolutions and settings. At 1920x1080: Low delivers 92 FPS average, Medium delivers 72 FPS average with a minimum of 61 FPS and maximum of 82 FPS, High delivers 54 FPS average, and Ultra delivers 51 FPS average. The spread from Low to Ultra is 41 FPS, which is a substantial range that gives users significant control over the performance/quality tradeoff.

At 2560x1440: Low delivers 74 FPS average, Medium delivers 58 FPS average with a minimum of 49 FPS and maximum of 66 FPS, High delivers 43 FPS average, and Ultra delivers 41 FPS average. The spread narrows to 33 FPS, indicating that the GPU is becoming more of a limiting factor at this resolution. The Medium preset's minimum of 49 FPS is the only data point below 50 FPS at this resolution, suggesting that frame pacing could be an issue during complex scenes.

At 3840x2160: Low delivers 55 FPS average, Medium delivers 43 FPS average with a minimum of 36 FPS and maximum of 49 FPS, High delivers 32 FPS average, and Ultra delivers 31 FPS average. The spread narrows further to 24 FPS, confirming that the GPU is saturated at 4K regardless of settings. The Medium preset's maximum of 49 FPS is lower than the Low preset's average of 55 FPS, which demonstrates that the GPU cannot maintain high frame rates even with reduced quality settings.

The progression from 1080p to 4K at each settings level is instructive. At Low, the drop is 92 → 74 → 55 FPS, a 40% total reduction. At Medium, the drop is 72 → 58 → 43 FPS, a 40% reduction. At High, the drop is 54 → 43 → 32 FPS, a 41% reduction. At Ultra, the drop is 51 → 41 → 31 FPS, a 39% reduction. The consistency of these percentages (39-41%) suggests that the game's rendering pipeline scales uniformly with resolution, and the GPU's memory bandwidth of 224.0 GB/s is the primary constraint at higher resolutions.

GPU Role

The AMD Radeon RX 6600 features 8 GB of GDDR6 memory on a 128-bit bus with 224.0 GB/s bandwidth. The GPU has 1,792 shading units, 112 TMUs, and 64 ROPs, with a base clock of 1626 MHz, game clock of 2044 MHz, and boost clock of 2491 MHz. The chip is built on TSMC's 7 nm process with 11,060 million transistors on a 237 mm² die. The pixel rate is 159.4 GPixel/s and the texture rate is 279.0 GTexel/s, with FP32 performance of 8.928 TFLOPS.

The 8 GB VRAM capacity is likely a contributing factor to the performance degradation at 4K. Microsoft Flight Simulator is known for loading large texture sets for terrain and aircraft, and 8 GB can be insufficient at 3840x2160 with higher presets. The fact that the Low preset at 4K achieves 55 FPS while the Ultra preset at 4K achieves only 31 FPS suggests that texture memory pressure is a significant factor, as the lower preset reduces the memory footprint and allows the GPU to operate more efficiently.

The GPU's general benchmark performance is modest, with a Passmark G3D score of 15,096 and a 3DMark Steel Nomad DX12 score of 1,492. The Geekbench Vulkan score of 67,623 and OpenCL score of 28,850 indicate that the GPU's compute capabilities are adequate for this game's requirements, but the memory bandwidth of 224.0 GB/s is a clear limitation. The 128-bit memory bus is narrow compared to higher-end cards, and this directly impacts the GPU's ability to feed its 1,792 shading units at high resolutions.

The GPU's TDP of 132 W and suggested PSU of 300 W indicate that this is a power-efficient card, but the performance data shows that it is simply not sufficient for Microsoft Flight Simulator at higher resolutions. The GPU's percentileVsAllGpus of 63 means it outperforms 63% of all GPUs, but this game's demands appear to exceed what this card can deliver at 4K with any preset other than Low.

CPU Role

The AMD Ryzen 7 9850X3D is an 8-core, 16-thread processor based on the Zen 5 architecture (Granite Ridge) built on TSMC's 4 nm process. It has a base clock of 4.70 GHz and boost clock of 5.60 GHz, with 96 MB of shared L3 cache. The CPU supports DDR5 memory with dual-channel configuration and 89.6 GB/s bandwidth, and it features PCIe Gen 5 with 24 lanes. The TDP is 120 W, and the processor was released on 2026-01-28 with a launch MSRP of $499.

The CPU's benchmark scores are impressive. It achieves a Cinebench R23 multicore score of 22,807 and single-core score of 2,228, with Cinebench R15 scores of 3,551 multicore and 343 single-core. Passmark scores include 41,318 for multithread, 4,704 for single-thread, and 4,171 for physics. The 96 MB of L3 cache is particularly relevant for Microsoft Flight Simulator, which benefits from large caches for terrain and object data.

In this game, the CPU's role appears to be secondary to the GPU. The fact that the combo ranks 2316th out of 2996 while the CPU ranks in the 92nd percentile suggests that the CPU is not the bottleneck. At 1080p Low, the system achieves 92 FPS, which is a reasonable frame rate for a flight simulator, but the CPU's capabilities suggest it could push much higher if the GPU were not limiting. The CPU's nearest rivals include the Intel Core i9-14900 (deltaPct 0.5), which is a high-end desktop processor, and the AMD Ryzen AI 9 HX 470 (deltaPct -0.7), which is a mobile part — the CPU is competitive with both.

The CPU's 8,315 million transistors on a 70.6 mm² die with 4 nm process technology represent a dense, efficient design. The 96 MB L3 cache is the standout feature for gaming workloads, and it likely helps maintain minimum frame rates in this game. However, the measured data shows that even with this cache advantage, the system cannot overcome the GPU's limitations at higher resolutions. The CPU's Passmark data compression score of 474,501 and encryption score of 22,856 are indicative of strong general-purpose performance, but these capabilities are not directly reflected in the game's frame rates.
