Microsoft Flight Simulator

Resolution Scaling

The performance curve across resolutions reveals that Microsoft Flight Simulator is heavily GPU-limited at 4K with this combination, while the CPU becomes more influential at 1080p. Moving from 1920x1080 to 2560x1440 on High settings drops the average frame rate from 91.9 FPS to 70.7 FPS, a 23% reduction. The jump from 1440p to 3840x2160 on the same preset is steeper: 70.7 FPS falls to 55.1 FPS, another 22% loss. This consistent scaling pattern indicates the AMD Radeon RX 9070's rendering throughput is the primary constraint as pixel count rises.

The Low preset tells a more revealing story about the CPU bottleneck. At 1080p Low, the combo reaches 156.4 FPS, but at 1440p Low it drops to 124 FPS, and at 4K Low it settles at 91.7 FPS. The 1080p-to-1440p gap of 32.4 FPS (21%) is nearly identical to the 1440p-to-4K gap of 32.3 FPS (26%), suggesting that even at Low settings, the GPU still governs scaling across the board. However, the fact that 1080p Low exceeds 150 FPS while 4K Ultra barely manages 47.6 FPS shows how dramatically the workload expands with resolution.

The Medium preset follows the same trajectory: 123.9 FPS at 1080p, 96.5 FPS at 1440p, and 72.4 FPS at 4K. Ultra settings compress the range further—87.8 FPS at 1080p, 71.2 FPS at 1440p, and 47.6 FPS at 4K—with the 1080p-to-1440p drop of 16.6 FPS being smaller in absolute terms than the 1440p-to-4K drop of 23.6 FPS. This widening gap at higher resolutions confirms that the RX 9070's memory bandwidth and shading resources become the decisive factor at 4K, while the Ryzen 5 5500's six cores can keep feeding frames adequately at lower pixel counts.

GPU Role

The AMD Radeon RX 9070 brings substantial resources to this flight simulator: 16 GB of GDDR6 memory on a 256-bit bus delivers 644.6 GB/s of bandwidth, which proves essential for streaming the vast terrain and photogrammetry data Microsoft Flight Simulator demands. The GPU's boost clock of 2520 MHz and game clock of 2070 MHz, built on the RDNA 4.0 architecture with 3584 shading units, produce 36.13 TFLOPS of FP32 compute. These specifications translate directly into the measured results: the card sustains playable frame rates at 4K High (55.1 FPS) and 1440p Ultra (71.2 FPS), showing it has enough headroom for high-fidelity flight over dense scenery.

The RX 9070's 128 ROPs and 564.5 GTexel/s texture rate handle the game's heavy fill-rate requirements at high resolutions. The 4K Ultra result of 47.6 FPS, while below the 60 FPS threshold many users target, demonstrates that the card's raw throughput is the limiting factor at maximum settings—not the CPU or memory subsystem. The VRAM capacity is never stressed in these tests, as even the most demanding 4K Ultra configuration stays within the 16 GB allocation, but the bandwidth utilization at 4K is what separates the High (55.1 FPS) from Medium (72.4 FPS) results.

How This Combo Ranks

This pairing of AMD Ryzen 5 5500 with AMD Radeon RX 9070 ranks 555th out of 1795 tested combinations in Microsoft Flight Simulator, placing it in the 69th percentile of all configs. That rank reflects a system that delivers solid 60+ FPS performance at 1440p across all settings except the most demanding presets, while struggling to maintain smooth frame rates at 4K Ultra. The ranking is respectable given that the CPU is a mid-range 2022 part paired with a 2025 GPU, but it also shows the processor is holding back the graphics card in this simulation-heavy title.

The CPU's overall benchmark percentile of 79 versus all processors, combined with the GPU's identical 79 percentile, suggests a balanced pairing on paper. Yet in practice, the combination's in-game rank of 555 out of 1795—roughly the top 31%—is slightly below what the component percentiles would predict. This gap indicates that Microsoft Flight Simulator's single-threaded rendering pipeline and physics calculations favor processors with stronger per-core performance than the Ryzen 5 5500's Zen 3 architecture provides, even though the GPU has ample headroom at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers strong performance across all presets. Low settings produce 156.4 FPS average, Medium reaches 123.9 FPS, High achieves 91.9 FPS, and Ultra drops to 87.8 FPS. The 1080p Ultra result is notable—it stays above 85 FPS, making maximum settings viable for high-refresh-rate monitors at this resolution. The gap between High and Ultra at 1080p is only 4.1 FPS, suggesting the additional visual fidelity costs little at this pixel count.

Moving to 2560x1440, the averages shift downward but remain playable: Low hits 124 FPS, Medium 96.5 FPS, High 70.7 FPS, and Ultra 71.2 FPS. Interestingly, the High and Ultra presets nearly converge at 1440p, differing by just 0.5 FPS. This suggests that beyond a certain quality threshold, the GPU's shading workload becomes the bottleneck, and the visual differences between High and Ultra do not translate into proportional frame rate penalties.

At 3840x2160, the results are more stratified: Low averages 91.7 FPS, Medium 72.4 FPS, High 55.1 FPS, and Ultra 47.6 FPS. The 4K Ultra figure is the only sub-48 FPS result in the entire dataset, indicating that this resolution/settings combination pushes the RX 9070 to its limits. The 4K Low result of 91.7 FPS shows the GPU can still deliver smooth performance at 4K when graphical effects are reduced, making it a viable option for users who prioritize frame rate over fidelity.

A: At 1080p, all presets exceed 87 FPS. At 1440p, High (70.7 FPS) and Ultra (71.2 FPS) both clear 60 FPS. At 4K, only Low (91.7 FPS) and Medium (72.4 FPS) exceed 60 FPS.

Settings Recommendations

For users with 1920x1080 displays, the Ultra preset at 87.8 FPS is the clear choice—it delivers the highest fidelity while maintaining frame rates well above 60 FPS. The gap between High (91.9 FPS) and Ultra is just 4.1 FPS, so the visual upgrade costs almost nothing in performance. At 2560x1440, Ultra at 71.2 FPS and High at 70.7 FPS are statistically identical, so users should select Ultra for maximum quality without sacrificing smoothness. The Medium preset at 96.5 FPS offers a substantial headroom for users with 144 Hz monitors, though the quality reduction may be noticeable in cockpit displays and distant terrain.

For 3840x2160 users, the recommendation depends on the target frame rate. Medium at 72.4 FPS provides the best combination of fidelity and smoothness, while High at 55.1 FPS is acceptable for users who prefer visual quality over frame rate consistency. The Low preset at 91.7 FPS is ideal for competitive or streaming scenarios where frame pacing matters more than detail. Ultra at 47.6 FPS should be avoided unless the user prioritizes screenshots or is willing to accept sub-50 FPS gameplay, as the visual gains over High are modest given the 7.5 FPS penalty.

CPU Role

The AMD Ryzen 5 5500 contributes six cores and twelve threads based on the Zen 3 architecture (Cezanne), with a base clock of 3.60 GHz and boost clock of 4.20 GHz. Its 16 MB of L3 cache and 51.2 GB/s memory bandwidth are modest by modern standards, but sufficient for a flight simulator that relies more on single-threaded physics and AI traffic calculations than multi-threaded rendering. The CPU's Cinebench R23 multi-core score of 16429 and single-core score of 2319 place it in the 79th percentile of all processors, indicating solid mid-range performance.

In Microsoft Flight Simulator, the CPU's role becomes apparent in the 1080p Low result of 156.4 FPS—this high frame rate suggests the processor can feed the GPU adequately in less demanding scenes. However, the CPU's 3dMark single-thread score of 836 and the 2-thread score of 1645 reveal that its per-core performance, while competent, is not exceptional. The nearest rivals—the Intel Core i5-12500 (average score 20897, delta -0.1%) and AMD Ryzen 5 PRO 4655GE (average score 20900, delta -0.1%)—show that the 5500 is competitively positioned within 0.2% of comparable processors, meaning the CPU is not an outlier in either direction.

The 4K results reinforce that the GPU dominates the performance envelope at higher resolutions, but the 1080p results indicate the CPU can become a limiting factor if users pair this processor with an even faster GPU or reduce settings further. With a TDP of 65 W and the AM4 socket, this CPU offers a balanced foundation for the RX 9070, though users seeking maximum frame rates at 1080p with lower settings might benefit from a processor with stronger single-thread performance. The CPU's launch MSRP of $159 reflects its mid-range positioning, and benchmark results confirm it performs accordingly—neither a bottleneck nor a standout at most settings in this game.
