Microsoft Flight Simulator

Microsoft Flight Simulator presents an unusually demanding workload, and the combination of the AMD Ryzen 9 5950X with the Intel Arc B390 produces a dataset that clearly illustrates the stark division of labor between CPU and GPU in this title. The measured frames per second (FPS) across resolutions and settings show a system where the processor has ample headroom, while the graphics solution becomes the primary constraint at every turn. The data indicates a configuration that is fundamentally imbalanced for this simulator, with the GPU's performance ceiling dictating the overall experience regardless of the CPU's capabilities.

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

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates with a base clock of 3.40 GHz and a boost clock of 4.90 GHz, and its 64 MB of L3 cache is a significant asset for handling large datasets. In synthetic benchmarks, this CPU demonstrates substantial multi-threaded prowess, scoring 26,017 in Cinebench R23 multi-core and 45,424 in Passmark multi-thread tests. Its single-thread performance is also strong, with a Cinebench R23 single-core score of 1,614 and a 3DMark single-thread score of 944. This combination of high core count and robust single-core speed places the 5950X in the 91st percentile of all CPUs, with an average benchmark score of 51,947.

The data suggests that this processor is not the limiting factor in Microsoft Flight Simulator. The game's engine is known for heavy single-thread dependency, but the 5950X's strong single-core results, evidenced by a Geekbench single-core score of 2,083, are more than sufficient to feed the GPU. In the measured FPS data, we see a clear pattern where performance scales directly with resolution and settings in a way that points to GPU limitation. For instance, at 1080p with Low settings, the system achieves 56 FPS on average. When the resolution is increased to 4K with the same Low settings, the average FPS drops to 33. This significant drop, despite the CPU's capabilities, indicates that the rendering workload is overwhelming the graphics processor, not the central processor.

The Ryzen 9 5950X's nearest rivals, based on average benchmark scores, include the Intel Core Ultra 5 235HX and the AMD EPYC 8124P. The 5950X is effectively tied with the Intel Core Ultra 5 235HX, showing a delta of -0.2%, and trails the AMD EPYC 8124P by -0.3%. These are all high-performance parts, and their similarity in average score confirms that the 5950X is a top-tier CPU. However, its performance in this game's measured FPS is entirely irrelevant to the final outcome, as the GPU bottleneck prevents the CPU from being exercised to its full potential. The processor is ready to handle complex flight models, AI traffic, and weather calculations, but the graphics pipeline is unable to keep pace, making the CPU role one of waiting rather than driving.

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

Analyzing the measured FPS data, the most playable experience is achieved at 1080p with the Low preset, which yields an average of 56 FPS. This is the only configuration that approaches a smooth 60 FPS target, and it is the clear choice for playability. The Medium preset at 1080p provides an average of 43 FPS, which is still within a functional range for a flight simulator, though it lacks the fluidity of the Low preset. The High and Ultra presets at 1080p drop to 33 and 31 FPS respectively, which is marginal for a game that requires precise control and smooth camera movement.

At 1440p, the situation becomes more constrained. The Low preset delivers an average of 45 FPS, which is playable but not ideal. The Medium preset at 1440p averages 35 FPS with a minimum of 30 FPS, making it a borderline experience. The High and Ultra presets at this resolution provide average FPS of 26 and 25, respectively, which are too low for a satisfactory experience. At 4K, all presets are below 33 FPS, with the Low preset being the only one to reach that figure. The Medium, High, and Ultra presets at 4K all average between 19 and 26 FPS, rendering this resolution impractical for smooth gameplay.

Given these numbers, the data recommends the 1080p Low preset as the only viable option for a consistently responsive experience. The step from Low to Medium at 1080p costs 13 FPS, a significant 23% reduction, which is a high price for the visual improvements. The data does not support any settings above Low at 1440p or 4K as providing a playable experience, as all average FPS figures fall below the 30 FPS threshold. The performance difference between Low and Ultra presets is consistent across all resolutions, with the Ultra preset being roughly 45% slower than Low, indicating that the GPU's fill rate and shading capacity are the primary bottlenecks for higher visual fidelity.

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

The FPS scaling across resolutions is a textbook example of GPU-bound behavior. Moving from 1080p to 1440p with the Low preset, the average FPS drops from 56 to 45, a reduction of 11 FPS or roughly 20%. Increasing the resolution further to 4K with the same Low preset results in an average of 33 FPS, which is a 41% drop from the 1440p figure and a 41% drop from the 1080p figure. This scaling pattern is consistent across all presets. For example, with the Medium preset, the average FPS goes from 43 at 1080p to 35 at 1440p and then to 26 at 4K. This clear and predictable degradation with each pixel count increase is the signature of a graphics processor that is saturated.

If the CPU were the limiting factor, we would expect to see less severe FPS drops when increasing resolution, as the CPU's workload per frame would remain relatively constant. Instead, the data shows that the Intel Arc B390's rendering capabilities are exhausted at 1080p, and every additional pixel demands a proportional amount of processing power that the GPU simply does not have. The performance differential between Low and High settings is also telling. At 1080p, the gap between Low and High is 23 FPS (56 to 33), but at 4K, that gap narrows to 14 FPS (33 to 19). This narrowing suggests that at higher resolutions, the GPU is so overwhelmed by the pixel fill rate that the complexity of the shading and effects has a relatively smaller impact on the total frame time, as the raw pixel throughput is the dominant cost.

The data strongly indicates that the frame rate is directly correlated with the number of pixels being rendered. The 4K Ultra preset, with an average of 19 FPS, is not a playable configuration, and the 1080p Low preset, at 56 FPS, is the only one that provides a comfortable margin. This analysis confirms that the Intel Arc B390 is the definitive limiting component in this system, and its low performance ceiling is the sole reason for the poor FPS at higher resolutions and settings.

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

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, with a 3 nm process node. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Its memory is System Shared, meaning it has no dedicated VRAM and relies on the system's main memory, with bandwidth that is System Dependent. The GPU features 1536 shading units, 48 texture mapping units, and 24 raster operation pipelines, along with 12 ray tracing cores. Its theoretical peak performance is 7.680 TFLOPS for FP32 operations.

The GPU's benchmark results are exceptionally low, with a 3DMark Steel Nomad DX12 score of 1482. This places it in the 9th percentile of all GPUs, and its nearest rivals are all legacy NVIDIA parts, such as the GeForce GT 520MX and GeForce GT 710. The deltaPct values show that the Arc B390 is only 1.3% faster than the GT 520MX and 2.7% faster than the GT 710. This is a clear indication that the Arc B390 is not a performance-oriented graphics solution, and its capabilities are far below what is required for a demanding simulator like Microsoft Flight Simulator.

The measured FPS data corroborates this. The 56 FPS at 1080p Low is the absolute ceiling, and it is a direct result of the GPU's limited fill rate and shading power. The lack of dedicated VRAM also contributes to the performance issues, as the system shared memory configuration can lead to bandwidth bottlenecks, especially at higher resolutions where more data needs to be moved. The data shows that the GPU is the sole reason for the low performance, as the Ryzen 9 5950X's capabilities are never fully utilized. The Arc B390's role in this system is to be the primary bottleneck, and its performance metrics fully explain the measured FPS results.

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

The complete dataset for this configuration is as follows. At 1920x1080, the Low preset achieves an average of 56 FPS. The Medium preset averages 43 FPS, with a minimum of 37 and a maximum of 50 FPS. The High preset averages 33 FPS, and the Ultra preset averages 31 FPS. At 2560x1440, the Low preset averages 45 FPS. The Medium preset averages 35 FPS, with a minimum of 30 and a maximum of 40 FPS. The High preset averages 26 FPS, and the Ultra preset averages 25 FPS. At 3840x2160, the Low preset averages 33 FPS. The Medium preset averages 26 FPS, with a minimum of 22 and a maximum of 30 FPS. The High and Ultra presets both average 19 FPS.

These numbers reveal a consistent pattern. The performance delta between Low and Ultra is substantial at every resolution, with the Ultra preset being roughly 45% slower than Low. The scaling from 1080p to 4K is also consistent, with the average FPS dropping by approximately 40-50% for each preset. The minimum FPS figures, where available, show that the system can experience significant frame drops, particularly at Medium settings. For example, at 1080p Medium, the minimum FPS of 37 is only 6 FPS lower than the average, but at 1440p Medium, the minimum of 30 is 5 FPS lower than the average. This suggests some frame pacing instability, but the overall trend is clear: the system is consistently GPU-limited, and the FPS is low across the board.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations for Microsoft Flight Simulator, this specific pairing of the AMD Ryzen 9 5950X and Intel Arc B390 ranks 2665th out of 2996 total combinations. This places it in the bottom 11% of all tested systems, a ranking that is entirely consistent with the measured FPS data. The rank is not a reflection of the CPU's quality, but rather a direct consequence of the GPU's extremely low performance. The Ryzen 9 5950X is a high-end processor, but in this context, its power is wasted because the Intel Arc B390 cannot translate that processing capability into frames.

The combo's rank is far below what the CPU alone would suggest. The CPU's 91st percentile ranking is meaningless when paired with a GPU that sits in the 9th percentile. This disparity highlights the importance of system balance. The data shows that this combination is severely bottlenecked, and the overall gaming experience is determined almost entirely by the weakest component. The rank of 2665 out of 2996 is a definitive statement that this is not a viable configuration for Microsoft Flight Simulator, as it falls into the lowest tier of performance. The system is capable of running the game, but only at the lowest settings and resolution, and even then, it does not provide a smooth experience.
