Microsoft Flight Simulator

The AMD Ryzen 5 5500X3D and NVIDIA GeForce RTX 5090 combination ranks 214th out of 2,996 tested combos in Microsoft Flight Simulator, placing it in the top 7.1% of all configurations. This is a strong result, though the pairing of a 6-core Zen 3 CPU with the flagship Blackwell GPU creates an interesting bottleneck dynamic that shows up clearly in the resolution scaling data. The RTX 5090 is clearly the dominant partner here, but the 5500X3D's 96 MB of shared L3 cache keeps frame rates remarkably consistent across settings tiers at every resolution.

How This Combo Ranks

The 214th position out of 2,996 tested combos puts this configuration firmly in the upper echelon of systems tested for Microsoft Flight Simulator. With 2,782 combinations ranked below it, this pairing outperforms roughly 93% of all tested configs, which is impressive given that the CPU is a mid-range 5000-series part while the GPU is the current flagship. The benchmark data indicates that the RTX 5090 is doing the heavy lifting, but the 5500X3D's large cache appears to prevent the kind of CPU-limited stuttering that often plagues flight simulators.

What makes this rank particularly notable is the CPU's position in the broader market. The 5500X3D sits at the 85th percentile among all CPUs, with an average benchmark score of 37,018. Its nearest rivals include the AMD Ryzen 5 5600F (36,945, +0.2%), the AMD Ryzen AI 7 PRO 450 (37,093, -0.2%), the Intel Core Ultra 5 225 (36,938, +0.2%), and the Intel Core i9-12900T (37,112, -0.3%). This means the 5500X3D is essentially performance-equivalent to a much newer AI-series chip and an older Core i9, which speaks to the efficiency of its Zen 3 architecture and 3D V-Cache design.

The combo rank of 214 suggests that while the GPU is top-tier, the CPU holds the configuration back from the very top positions. Systems ranked above 214 likely pair the RTX 5090 with higher-core-count or newer-generation CPUs. However, for a 6-core, 12-thread processor with a 3.00 GHz base and 4.00 GHz boost clock, the 5500X3D delivers frame rates that will satisfy most users of this game. The data shows that even at 4K Ultra, this combo maintains playable performance, which is the real story here.

GPU Role

The NVIDIA GeForce RTX 5090 is the undisputed star of this configuration. Built on the Blackwell 2.0 architecture with a 5 nm process, this GPU packs 21,760 shading units, 680 texture mapping units, and 176 raster operation units. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is critical for Microsoft Flight Simulator's massive texture streaming demands. The 170 RT cores and 680 tensor cores also contribute to the game's rendering pipeline, though flight simulators are less dependent on ray tracing than other genres.

The GPU's clock behavior shows a base frequency of 2017 MHz with a boost of 2407 MHz, and the memory runs at 1750 MHz (28 Gbps effective). These clocks, combined with the enormous memory bandwidth, explain why the RTX 5090 achieves a 92nd percentile ranking among all GPUs. Its average benchmark score of 79,842 puts it just ahead of the NVIDIA Tesla P100 PCIe 16 GB (79,605, +0.3%) and the Tesla P100 PCIe 12 GB (79,396, +0.6%), while trailing the AMD Radeon Pro Vega 64X (80,959, -1.4%) by a small margin.

In the context of Microsoft Flight Simulator specifically, the GPU's role is to handle the complex geometry, dynamic lighting, and high-resolution textures that define the game's visual experience. The measured FPS data shows that the RTX 5090 scales predictably with settings changes, but the CPU becomes a limiting factor at lower resolutions. At 1080p Low, the combo hits 155 FPS average, but at 4K Ultra, it drops to 79 FPS. This 76 FPS spread across the settings range is substantial, but the GPU's raw compute power (104.8 TFLOPS FP32) ensures that even the most demanding settings remain playable.

Resolution Scaling

The resolution scaling data reveals a clear pattern: this combo is GPU-bound at 4K but becomes increasingly CPU-limited as resolution drops. Moving from 1080p to 1440p to 4K at the same settings shows diminishing FPS losses that point to where the bottleneck lies. At High settings, the average FPS goes from 127 at 1080p to 112 at 1440p to 83 at 4K. That is a 15 FPS drop from 1080p to 1440p, but a 29 FPS drop from 1440p to 4K, indicating the GPU is being pushed harder at the higher resolution.

The Low settings tell a similar but more revealing story. At 1080p Low, the combo achieves 155 FPS, which drops to 144 FPS at 1440p and 130 FPS at 4K. The relatively small gap between 1080p and 1440p (11 FPS) compared to the gap between 1440p and 4K (14 FPS) suggests that at lower settings, the CPU is beginning to cap performance. At 1080p Low, the 5500X3D's 6 cores and 12 threads are likely maxing out, preventing the RTX 5090 from reaching its full potential.

Ultra settings show the most dramatic scaling: 125 FPS at 1080p, 107 FPS at 1440p, and 79 FPS at 4K. The 28 FPS difference between 1440p and 4K is the largest across all settings, confirming that the RTX 5090's memory bandwidth is being saturated at the highest resolution. The Medium settings, which include min and max FPS data, show 141 average at 1080p (min 120, max 162), 131 average at 1440p (min 112, max 151), and 110 average at 4K (min 94, max 127). These ranges indicate that the CPU is causing occasional frame dips even at Medium settings, though the overall experience remains smooth.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce 155 FPS average, which is excellent for flight simulation where smoothness matters. Medium settings drop to 141 FPS with a minimum of 120 and maximum of 162, showing good consistency. High settings yield 127 FPS, and Ultra settings come in at 125 FPS. The relatively small gap between High and Ultra at 1080p (just 2 FPS) suggests that the CPU is limiting performance at this resolution, as the GPU can handle the extra graphical load without much penalty.

Moving to 2560x1440, the frame rates remain strong but show expected declines. Low settings average 144 FPS, Medium averages 131 FPS (min 112, max 151), High averages 112 FPS, and Ultra averages 107 FPS. The 4 FPS difference between High and Ultra at 1440p is slightly larger than at 1080p, indicating the GPU is starting to become more involved in the performance equation. The Medium settings range from 112 to 151 FPS, which represents a 39 FPS spread — the widest at this resolution, suggesting some scenes are more demanding than others.

At 3840x2160, the RTX 5090's power becomes essential. Low settings still manage 130 FPS, which is remarkable for 4K gaming. Medium settings average 110 FPS (min 94, max 127), High settings drop to 83 FPS, and Ultra settings bottom out at 79 FPS. The gap between High and Ultra at 4K is only 4 FPS, similar to 1440p, but the overall reduction from 1080p Ultra (125 FPS) to 4K Ultra (79 FPS) represents a 37% performance loss. This is where the 32 GB of GDDR7 memory and 1.79 TB/s bandwidth prove their worth, as the game can load and stream massive textures without stuttering.

Settings Recommendations

For users prioritizing smoothness and visual fidelity, the High settings at 1440p present the best balance in the measured data. At 112 FPS average, this configuration provides well over 60 FPS headroom while maintaining the visual quality that makes Microsoft Flight Simulator immersive. The jump from High to Ultra at 1440p costs only 5 FPS (107 vs 112), so users with high-refresh-rate displays might prefer Ultra for the marginal visual gains without significant performance loss.

At 4K, the Medium settings offer the most compelling experience. The 110 FPS average with a minimum of 94 FPS ensures that even demanding scenes stay above 90 FPS, which is critical for a game where smooth panning over terrain is constant. Ultra at 4K drops to 79 FPS, which is still playable, but the 31 FPS penalty compared to Medium is substantial. Given that the Medium settings show a min FPS of 94 at 4K, this preset provides the most consistent experience without requiring users to sacrifice too much visual quality.

For 1080p users, the High preset at 127 FPS is the recommended starting point. The 2 FPS difference between High and Ultra at this resolution means there is little reason to avoid Ultra if the display supports it, but High offers slightly more stability. The Low preset at 155 FPS is only useful for competitive or recording scenarios where maximum frame rate is required, as the visual degradation is significant. The data shows that at 1080p, the CPU is the limiting factor beyond High settings, so users should not expect major gains from lowering settings below High.

CPU Role

The AMD Ryzen 5 5500X3D is a 6-core, 12-thread processor based on the Zen 3 architecture (Vermeer codename) manufactured on TSMC's 7 nm process. With a base clock of 3.00 GHz and boost clock of 4.00 GHz, it operates at a modest frequency, but its 96 MB of shared L3 cache is the key feature for gaming. The 5500X3D's 85th percentile ranking among all CPUs reflects its strong gaming performance despite its lower core count, and its PassMark single-thread score of 2,941 and multithread score of 20,363 confirm its capabilities.

In Microsoft Flight Simulator, the CPU handles the simulation logic, physics calculations, and AI traffic that populate the world. The 5500X3D's large L3 cache helps reduce memory latency when accessing the game's massive dataset, which is why the frame rates remain relatively high even at 1080p where the GPU is not stressed. The PassMark physics score of 2,282 and floating-point math score of 34,511 indicate that the CPU can handle the complex calculations required for realistic flight dynamics.

The bottleneck behavior becomes clear when comparing the CPU's performance to its nearest rivals. The 5500X3D scores nearly identically to the Ryzen 5 5600F (0.2% higher), the Ryzen AI 7 PRO 450 (0.2% lower), the Core Ultra 5 225 (0.2% higher), and the Core i9-12900T (0.3% lower). This means that while the 5500X3D is not a standout in raw compute, its 3D V-Cache design provides gaming-specific benefits that generic benchmarks do not fully capture. In this game, the CPU's role is to feed the RTX 5090 with enough simulation data to keep frame rates high, and the data shows it succeeds at 1440p and 4K, but caps performance at 1080p where the GPU is underutilized.
