# Microsoft Flight Simulator — AMD Ryzen 9 9900X + NVIDIA GeForce RTX 4080

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4080 combination delivers strong, playable performance across all tested settings in Microsoft Flight Simulator, with the data showing that the system handles the game's demanding simulation workload capably at every resolution from 1080p through 4K. The measured results place this combo at rank 215 out of 3,714 tested combinations, putting it in the top 6% of all systems tested for this title.

CPU Role

The AMD Ryzen 9 9900X brings 12 cores and 24 threads to Microsoft Flight Simulator, running on the Zen 5 architecture with a base clock of 4.40 GHz and a boost clock of 5.60 GHz. This processor, built on a 4 nm process at TSMC, is part of the 9000 series and uses the AMD Socket AM5 platform with DDR5 memory support. The CPU's substantial thread count proves valuable in a game like Flight Simulator, which must simulate physics, weather, and aircraft systems simultaneously with rendering tasks.

The 9900X's benchmark profile shows strong multi-threaded performance, with a Cinebench R23 multi-core score of 32,172 and a single-core score of 2,253. The 3DMark results demonstrate scalability across thread counts: 2,519 with 2 threads, 4,886 with 4 threads, 9,114 with 8 threads, 12,552 with 16 threads, and 13,929 with maximum threads. This scaling pattern indicates the CPU can effectively utilize additional cores, which matters in Flight Simulator's complex simulation loops.

However, the data reveals that in this game, the CPU's role becomes less dominant as resolution increases. At 1080p Low settings, the system achieves 211 FPS, but the frame rate drops to 170 FPS at 1440p and 125 FPS at 4K — a pattern that suggests the CPU is capable of feeding the GPU far more frames than the GPU can render at higher resolutions. The 9900X's single-thread performance (3DMark single-thread score of 1,286, Geekbench single-core 3,010) ensures that the game's primary simulation thread, which typically runs on one or two cores, does not become a bottleneck at lower resolutions.

The CPU's 64 MB of L3 cache and 89.6 GB/s memory bandwidth provide ample headroom for the game's streaming-heavy workload, where terrain and scenery data constantly flow through the system. Compared to its nearest rivals in the CPU benchmark database, the 9900X sits within 1.4% of the Intel Core i9-14900 and the Intel Xeon Platinum 8260M, while performing slightly ahead of the AMD EPYC 7313 by 0.2% and trailing the EPYC 9015 by only 0.1%. This tight grouping indicates that the 9900X's simulation performance is competitive with other high-end processors, though the game's actual frame rates will ultimately depend on the GPU at higher resolutions.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset delivers the best experience. At 4K, the High preset produces an average of 73 FPS, while Ultra drops to 70 FPS — both playable, but only marginally so. The Medium preset at 4K yields 97 FPS with a minimum of 83 FPS and maximum of 112 FPS, offering a substantial improvement in smoothness. The Low preset at 4K reaches 125 FPS, which exceeds what most displays at this resolution can show, but the visual quality trade-off is significant.

At 1440p, the picture improves considerably. The High preset achieves 99 FPS, and Ultra delivers 95 FPS — both well within smooth territory. The Medium preset at 1440p provides 132 FPS average with a minimum of 112 FPS, making it the most robust option for high-refresh-rate displays. Low at 1440p hits 170 FPS, which is ample for even the fastest gaming monitors.

For 1080p, all presets deliver high frame rates. Ultra runs at 117 FPS, High at 123 FPS, and Medium at 164 FPS with a minimum of 139 FPS. The Low preset reaches 211 FPS, which is the highest measured value across all configurations.

Given the data, the Medium preset at 1440p appears to be the sweet spot for this combination: it provides 132 FPS average with a minimum that stays above 110 FPS, while the visual upgrade from Low to Medium is substantial in a flight simulator where reading instruments and ground details matters. For 4K users, the Medium preset at 97 FPS offers the best balance, as the jump from Medium to High costs 24 FPS (from 97 to 73) while the visual difference is less pronounced in this title's rendering style.

How This Combo Ranks

The combo rank of 215 out of 3,714 tested combinations places this system in the 94th percentile for Microsoft Flight Simulator performance. This ranking indicates that the Ryzen 9 9900X and RTX 4080 pairing outperforms the overwhelming majority of systems tested, though it does not reach the very top tier.

The CPU's own percentile of 92 among all CPUs, combined with the GPU's percentile of 86 among all GPUs, suggests a well-matched pairing where neither component dramatically outclasses the other. The CPU's average benchmark score of 57,498 places it within 0.1% of the AMD EPYC 9015 (57,555) and 0.2% ahead of the AMD EPYC 7313 (57,399), while trailing the Intel Core i9-14900 by 1.1% and the Intel Xeon Platinum 8260M by 1.4%. The GPU's average score of 54,247 sits 0.1% above the RTX 4080 SUPER (54,209) but 1.1% below the AMD Radeon Pro W5700X (54,828) and 2.6% below the AMD Radeon RX 6750 GRE 12 GB (55,698).

This ranking context matters for interpreting the measured FPS: the system is not at the extreme top of the performance pyramid, but it is firmly in the upper echelon. The 215th position out of 3,714 means there are only 214 systems that perform better in this specific game, which is a strong result for a desktop CPU and GPU combination that also excels at general productivity workloads.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with the AD103 chip at 5 nm, containing 45,900 million transistors on a 379 mm² die. The GPU operates at a base clock of 2,205 MHz and boosts to 2,505 MHz, with 16 GB of GDDR6X memory running at 22.4 Gbps effective on a 256-bit bus for a bandwidth of 716.8 GB/s. The 9,728 shading units, 304 TMUs, and 112 ROPs provide the raw rendering throughput, while the 76 RT cores and 304 tensor cores handle ray tracing and AI-accelerated features.

The GPU's benchmark profile shows it performs well in synthetic tests, with a Passmark G3D score of 34,457 and a Geekbench Vulkan score of 263,779. The 3DMark Steel Nomad DX12 score of 6,567 indicates strong DirectX 12 performance, which is relevant for Microsoft Flight Simulator's rendering pipeline.

In this game, the RTX 4080's role becomes increasingly dominant as resolution rises. The measured FPS data shows that the GPU's rendering capacity determines frame rates at 4K, where the CPU has ample headroom. The 16 GB of VRAM provides sufficient capacity for the game's large texture sets and high-resolution terrain data, preventing any memory-related stuttering at 4K Ultra settings.

The GPU's 86th percentile ranking among all GPUs places it just above the RTX 4080 SUPER (0.1% higher average score) and ahead of the AMD Radeon Pro W5700X by 1.1%. However, the AMD Radeon RX 6750 GRE 12 GB and AMD Radeon 8060S both outperform it in average benchmark score by 2.6% and 2.7% respectively, which is an interesting data point — though the RTX 4080's feature set and driver optimization for Flight Simulator may offset these synthetic benchmark differences in real-world gameplay.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture of performance across resolutions and settings. At 1080p, the system produces 211 FPS at Low, 164 FPS at Medium (minimum 139, maximum 188), 123 FPS at High, and 117 FPS at Ultra. These figures demonstrate that the system has significant headroom at 1080p, with even the Ultra preset exceeding 115 FPS.

Moving to 1440p, the frame rates remain strong but show the expected decline. Low settings deliver 170 FPS, Medium produces 132 FPS (minimum 112, maximum 152), High reaches 99 FPS, and Ultra achieves 95 FPS. The gap between Low and Ultra at 1440p is 75 FPS, reflecting the increased GPU workload at this resolution.

At 4K, the performance curve steepens. Low settings yield 125 FPS, Medium produces 97 FPS (minimum 83, maximum 112), High drops to 73 FPS, and Ultra falls to 70 FPS. The 4K results show that the system remains playable across all presets, but the margin above 60 FPS narrows considerably at High and Ultra.

It is notably only the Medium preset at each resolution includes minimum and maximum FPS data. At 1080p Medium, the minimum of 139 FPS ensures consistent smoothness. At 1440p Medium, the minimum of 112 FPS remains above the 100 FPS threshold. At 4K Medium, the minimum of 83 FPS still provides a comfortable margin above 60 FPS, though frame pacing may be less consistent than at lower resolutions.

Resolution Scaling

The FPS drop from 1080p to 4K reveals important information about the limiting component in this system. At Low settings, the system produces 211 FPS at 1080p, 170 FPS at 1440p, and 125 FPS at 4K. This represents a 20% drop from 1080p to 1440p and a further 26% drop from 1440p to 4K, for a total reduction of 41% from 1080p to 4K.

At Medium settings, the pattern shifts slightly: 164 FPS at 1080p, 132 FPS at 1440p, and 97 FPS at 4K. The percentage drops are 20% and 27%, respectively, totaling 41% — nearly identical to the Low setting's scaling. This consistency suggests that the rendering workload scales predictably with pixel count, and the system's performance is limited by whichever component — CPU or GPU — hits its capacity first.

At High settings, the numbers are 123 FPS at 1080p, 99 FPS at 1440p, and 73 FPS at 4K, with drops of 20% and 26% and a total of 41%. Ultra settings follow suit: 117 FPS, 95 FPS, and 70 FPS, with drops of 19% and 26%, totaling 40%. The remarkable consistency across all settings — with total reductions from 1080p to 4K ranging from 40% to 41% — indicates that the system's scaling behavior is determined primarily by the GPU's rendering capacity, not by CPU limitations.

If the CPU were the primary bottleneck, we would expect to see smaller FPS differences between resolutions at Low settings (where the CPU has more work relative to the GPU). Instead, the data shows that even at Low settings, the FPS drops by 41% from 1080p to 4K, which aligns with the GPU having to render four times as many pixels. The RTX 4080's 716.8 GB/s memory bandwidth and 280.6 GPixel/s pixel rate are the key specifications driving this scaling behavior, and the measured results confirm that the GPU is the limiting component at 4K across all settings presets.
