Microsoft Flight Simulator

The Intel Core i5-14600KF paired with the Intel Arc B370 presents a starkly asymmetric profile in Microsoft Flight Simulator. The CPU is a high-end desktop part, while the GPU is an integrated-class solution with a 5th percentile ranking among all GPUs. The measured frame rates confirm this imbalance: the combo ranks 2770th out of 2996 tested combinations, placing it in the bottom 8% of all systems. This analysis examines how the resolution scaling, CPU capabilities, and GPU limitations shape the playability of this specific pairing.

Resolution Scaling

The data reveals a predictable but severe drop in performance as resolution increases, confirming the GPU as the dominant bottleneck. At 1080p with Low settings, the combo achieves an average of 50 FPS. Moving to 1440p at the same settings drops the average to 41 FPS, a reduction of 18%. At 4K, the average falls to 30 FPS, which is exactly 40% lower than the 1080p figure. This scaling pattern indicates that even at the lowest graphical preset, the rendering load at higher resolutions quickly overwhelms the GPU's capabilities.

The impact is even more pronounced at higher settings. At High preset, the average frame rate drops from 30 FPS at 1080p to 24 FPS at 1440p, and finally to 18 FPS at 4K. This represents a 40% reduction from 1080p to 4K at High settings. The Ultra preset shows a similar trend: 28 FPS at 1080p, 23 FPS at 1440p, and 17 FPS at 4K. The consistency of these percentage drops across different quality presets strongly suggests that the limiting factor is the GPU's raw pixel throughput rather than any specific setting.

The Medium preset provides the only complete dataset with min and max FPS values. At 1080p Medium, the average is 39 FPS with a range of 33 to 45 FPS. At 1440p Medium, the average drops to 32 FPS with a range of 27 to 36 FPS. At 4K Medium, the average falls to 23 FPS with a range of 20 to 27 FPS. The frame time consistency appears to hold up relatively well even as the average drops, but the absolute numbers at 4K are below the threshold for smooth flight simulation.

The data indicates that 1080p is the only resolution where this combo approaches playable performance, and even then only at lower presets. The 4K results are uniformly poor, with the best case being 30 FPS at Low settings. The scaling curve shows that the CPU has ample headroom to feed the GPU at high frame rates, but the GPU cannot keep up as pixel count increases. This is a textbook case of a GPU-limited configuration where resolution scaling directly translates to proportional frame rate losses.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor from the Raptor Lake Refresh generation, running on the Intel Socket 1700 platform. Its base clock is 3.50 GHz with a boost clock of 5.30 GHz. This is a desktop-class CPU with a 125 W TDP, and its benchmark scores place it in the 90th percentile of all CPUs tested. The Cinebench R23 multi-core score of 32544 and single-core score of 4594 indicate strong performance in both heavily threaded and lightly threaded workloads.

In Microsoft Flight Simulator, the CPU's role is to handle the complex simulation logic, including flight physics, weather systems, and the vast amount of terrain and building data streaming. The 14-core configuration with 20 threads provides substantial parallel processing capability. The CPU's nearest rivals in terms of average benchmark score include the AMD Ryzen 9 7900 at 0.3% higher score and the Intel Core Ultra 5 245 at 0.8% higher score, showing that the i5-14600KF is competitive with much more expensive processors.

However, the measured FPS data shows that the CPU is not the limiting factor in this configuration. The single-core performance, which is often critical for simulation games, is robust enough to drive the frame rates seen in the data. If the CPU were the bottleneck, we would expect to see similar frame rates regardless of resolution, since the simulation workload would be constant. Instead, the frame rates drop significantly with each resolution increase, which is the hallmark of a GPU bottleneck.

The CPU's large L3 cache of 24 MB (shared) and per-core L2 cache of 2 MB help with the data-heavy nature of flight simulation. The processor supports both DDR4 and DDR5 memory, though the memory bandwidth is not specified in the data. The 20 threads allow the CPU to handle background tasks like asset decompression and AI traffic without stalling the main simulation thread. In essence, the i5-14600KF is far more capable than what the Arc B370 can utilize in this game, leaving significant CPU performance on the table.

GPU Role

The Intel Arc B370 is a fundamentally different class of hardware. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture with a Panther Lake chip, manufactured on a 3 nm process. Its TDP is just 25 W, and it has no dedicated memory, using System Shared memory instead. The GPU has 1280 shading units, 40 TMUs, and 20 ROPs, along with 10 ray tracing cores. Its boost clock reaches 2400 MHz from a base of 300 MHz.

The GPU's benchmark results are starkly revealing. Its 3DMark Steel Nomad DX12 score is 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 (0.2% higher score), ATI Radeon HD 5770 (0.5% higher), and AMD Radeon HD 7650M (0.7% higher). These are all legacy or low-end mobile parts from over a decade ago, illustrating just how limited the Arc B370's raw performance is.

In Microsoft Flight Simulator, the GPU is responsible for rendering the highly detailed terrain, aircraft models, and dynamic lighting. The data shows that the Arc B370 simply cannot handle modern flight simulation at high resolutions. The maximum average frame rate achieved across all tested scenarios is 50 FPS at 1080p Low. At any setting above Low, the frame rates fall below 40 FPS at 1080p, and at 4K they never exceed 30 FPS even at Low.

The GPU's memory configuration of System Shared means that performance is also dependent on the system's RAM speed and allocation, which adds another layer of variability. The 6.144 TFLOPS of FP32 compute is far below what modern discrete GPUs offer. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are the metrics that directly impact resolution scaling, and they are insufficient for 1440p or 4K gaming in this title. The data clearly shows that the GPU is the primary constraint, with the CPU waiting idle for the GPU to finish rendering each frame.

How This Combo Ranks

The combo rank of 2770 out of 2996 tested combinations places this system in the bottom 7.5% of all configurations tested in Microsoft Flight Simulator. This ranking is a direct consequence of the GPU's limitations, as the CPU alone would rank much higher based on its 90th percentile standing among all CPUs. The system is effectively a high-end CPU paired with an entry-level integrated GPU, which creates a severe imbalance.

Looking at the measured frame rates, the best case scenario for this combo is 50 FPS at 1080p Low, which is the only configuration that reaches a playable threshold. The 4K results are uniformly below 30 FPS, with the Ultra preset at 17 FPS being the worst case. These numbers place the combo in the lower tier of systems for this game, suitable only for low-resolution or low-detail gaming.

The ranking data suggests that most other tested combos, including those with older or weaker CPUs but discrete GPUs, outperform this pairing. The GPU's 5th percentile ranking is the dominant factor in the overall combo rank. While the i5-14600KF provides excellent CPU-side performance, it cannot compensate for the GPU's inability to render the game at acceptable frame rates. The system is well-suited for CPU-intensive tasks but poorly suited for this graphics-heavy flight simulator.

Settings Recommendations

The measured data provides a clear hierarchy of playability for this specific combo. The primary recommendation is to target 1080p resolution, as it is the only resolution where any preset achieves an average above 30 FPS. At 1080p, the Low preset delivers 50 FPS, which is the smoothest experience available. This should be the default setting for users who prioritize frame rate stability.

For those who want slightly better visual quality, the Medium preset at 1080p offers 39 FPS with a range of 33 to 45 FPS. This is a reasonable compromise, as the average remains above 30 FPS and the minimum frame rate is still playable. The High preset at 1080p drops to 30 FPS average, which is borderline for a flight simulator where smooth camera panning is important. The Ultra preset at 1080p falls to 28 FPS, which is not recommended.

At 1440p, the situation becomes more constrained. The Low preset at 41 FPS is the only playable option at this resolution. The Medium preset at 32 FPS is technically playable but may suffer from occasional dips, especially in dense urban areas or complex weather scenarios. The High preset at 24 FPS and Ultra at 23 FPS are too low for comfortable gameplay.

The 4K resolution is not viable for this combo in Microsoft Flight Simulator. Even the Low preset at 30 FPS is marginal, and the Medium preset at 23 FPS, High at 18 FPS, and Ultra at 17 FPS are all below acceptable thresholds. There is no setting combination at 4K that provides a consistently smooth experience. For the best experience, users should run this game at 1080p with Low or Medium settings, accepting that the visual fidelity will be limited by the integrated GPU.
