Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title, and the combination of the AMD Ryzen 5 5600X and the Intel Arc B370 produces results that are firmly constrained by the graphics subsystem. The measured data reveals a configuration that is capable of running the simulator, but only at lower resolutions and with significant compromises to visual fidelity. The benchmark results indicate a system that prioritizes CPU processing power—the Ryzen 5 5600X is a strong contender in its class—but pairs it with an integrated GPU that lacks the raw throughput for high-fidelity flight simulation. This analysis will break down the performance metrics across resolutions and settings, examine the roles of the CPU and GPU, and provide specific recommendations based on the measured frames per second (FPS).

Resolution Scaling

The performance degradation from 1080p to 4K is steep and consistent, clearly identifying the Intel Arc B370 as the primary limiting factor. At the "Low" settings preset, the average FPS drops from 50 at 1920x1080 to 41 at 2560x1440, a reduction of 9 FPS, and then falls further to 30 at 3840x2160, another 11 FPS decrease. This pattern shows that the GPU is being saturated as the pixel count increases, with each step up in resolution exacting a heavy toll on frame rates.

This trend is mirrored across all settings presets. For instance, at "Medium" settings, the average FPS scales from 39 at 1920x1080, down to 32 at 2560x1440, and finally to 23 at 3840x2160. The "High" preset follows a similar trajectory, with averages of 30, 24, and 18 FPS across the three resolutions, respectively. The uniformity of these drops indicates a purely GPU-bound scenario; the CPU is not the bottleneck here, as the frame rate is directly proportional to the number of pixels being rendered.

The data suggests that the Intel Arc B370, with its 25 W TDP and system-shared memory, simply cannot handle the fill-rate demands of 4K in this simulator. The jump from 1080p to 1440p alone costs roughly 18-20% of the performance, and moving to 4K from 1440p costs an additional 27-30%. This is a classic sign of a GPU that is running out of memory bandwidth and raw shading power. For this combo, 1080p is the only resolution where playable frame rates are consistently achievable, and even then, only at lower settings presets. The scaling behavior indicates that any attempt to run this game at high resolutions will result in a sub-30 FPS experience, which is not ideal for a flight simulator that requires smooth camera panning and instrument readability.

GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture and built on Intel's 3 nm process. Its performance profile is the central story of this benchmark. The GPU holds a percentile rank of just 5 among all tested GPUs, indicating that it is in the bottom 5% of the performance spectrum. Its single benchmark score in 3DMark Steel Nomad DX12 is 1184, placing it in direct competition with legacy parts like the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, which score 1186 and 1190, respectively. This context is crucial: this is not a gaming-grade discrete GPU.

The card's specifications reinforce this assessment. It has 1280 shading units, 40 texture mapping units (TMUs), and 20 render output units (ROPs). Its boost clock is rated at 2400 MHz, and it offers a FP32 performance of 6.144 TFLOPS. While these numbers might seem moderate on paper, the key limitation is its memory configuration: the memory size, type, and bus width are all listed as "System Shared," with bandwidth described as "System Dependent." This means the GPU is using the system's main DDR4 memory, which is shared with the CPU. This architecture is a significant handicap in a game like Microsoft Flight Simulator, which streams vast amounts of terrain and scenery data, demanding high memory bandwidth that shared system memory cannot provide.

The measured FPS data reflects this. At the "Ultra" preset, the GPU delivers an average of 28 FPS at 1080p, which drops to 23 FPS at 1440p and 17 FPS at 4K. These are not playable frame rates for a smooth experience. The "High" preset at 1080p yields only 30 FPS on average. The GPU's role is clear: it is the bottleneck in this configuration, and its performance limits the entire system to low-to-medium settings at 1080p to achieve frame rates that approach playability. The data shows that the Arc B370 is only suitable for the most basic graphical demands of this simulator.

Settings Recommendations

Based on the measured FPS rows, the optimal experience for this combination is to use the "Low" settings preset at 1920x1080 resolution. This is the only configuration that produces an average frame rate of 50 FPS, which is the highest measured average across all tested combinations. This preset provides a significantly smoother experience compared to the alternatives, which all fall below 40 FPS at this resolution.

Choosing the "Medium" preset at 1080p results in an average of 39 FPS, with a minimum of 33 and a maximum of 45 FPS. While this is a 22% drop in average frame rate compared to "Low," it would offer improved visual fidelity. However, for a flight simulator where smoothness is paramount for accurate control and situational awareness, the higher frame rate of the "Low" preset is preferable. At 1440p, the "Low" preset is the only one that breaks the 40 FPS barrier, averaging 41 FPS; all other settings at this resolution fall to 32 FPS or below.

The data strongly suggests avoiding the "High" and "Ultra" presets entirely. At 1080p, these presets yield average FPS of 30 and 28, respectively, which is marginal. At 1440p, "High" (24 FPS) and "Ultra" (23 FPS) are effectively unplayable, and the 4K results are all below 31 FPS, even at "Low" settings. Therefore, the only sensible recommendation is to prioritize frame rate over fidelity. For users who can tolerate lower visual quality, the "Low" preset at 1080p is the clear winner, offering a playable and responsive simulation environment. The "Medium" preset at 1080p is a secondary option for those who want a slight graphical upgrade and can accept a lower, but still potentially manageable, frame rate.

Measured FPS Breakdown

The complete set of measured frame rates provides a detailed look at the performance envelope of this hardware combination. At 1920x1080, the results are as follows: the "Low" preset achieves an average of 50 FPS, making it the single best result in the entire dataset. The "Medium" preset averages 39 FPS, with a recorded minimum of 33 FPS and a maximum of 45 FPS. The "High" preset averages 30 FPS, and the "Ultra" preset averages 28 FPS. This resolution is the only one where the simulator approaches a smooth experience, and only at "Low" and "Medium" settings.

Moving to 2560x1440, the performance drops considerably. The "Low" preset is the only one to maintain an average above 40 FPS, hitting 41 FPS. The "Medium" preset averages 32 FPS, with a minimum of 27 and a maximum of 36 FPS. The "High" preset falls to an average of 24 FPS, and the "Ultra" preset averages 23 FPS. At this resolution, the frame rates are consistently below the threshold for a fluid simulation, suggesting that 1440p is not a viable target for this configuration beyond the lowest settings.

At 3840x2160, the performance collapses, confirming the GPU is severely underpowered for 4K. The "Low" preset averages 30 FPS, which is the only preset to reach 30 FPS. The "Medium" preset averages 23 FPS, with a minimum of 20 and a maximum of 27 FPS. The "High" preset averages only 18 FPS, and the "Ultra" preset averages 17 FPS. These numbers indicate that 4K is not a functional resolution for this combo, as even the lowest settings cannot provide a consistently smooth frame rate. The data across all resolutions shows a clear and consistent hierarchy: lower settings always yield higher FPS, and lower resolutions always yield higher FPS.

How This Combo Ranks

In the grand scheme of the benchmark database for Microsoft Flight Simulator, this specific combination of the AMD Ryzen 5 5600X and the Intel Arc B370 ranks at position 2770 out of 2996 tested combos. This places it in the bottom 8% of all configurations tested, a ranking that underscores the severe performance limitations of the integrated GPU. The CPU is not the reason for this low rank; the Ryzen 5 5600X is a capable processor, but it is paired with a graphics solution that cannot keep up with the demands of the game.

The GPU's individual standing is the primary driver of this low combo rank. As mentioned earlier, the Arc B370's percentile rank is 5, meaning it outperforms only 5% of all GPUs in the database. Its nearest rivals in terms of raw compute power are all legacy or entry-level parts from over a decade ago. This context makes the combo's rank of 2770 unsurprising. While the CPU is in the 75th percentile of all CPUs, its performance is almost entirely negated by the GPU bottleneck in this gaming workload. The data shows that the overall ranking is a direct reflection of the weakest link in the chain, which is unequivocally the graphics processor. This combination confirms how a strong CPU cannot compensate for an underpowered GPU in a graphically intensive simulation.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. Its performance data shows it is a strong CPU, ranking in the 75th percentile of all processors. Its Cinebench R23 multi-core score of 11838 and single-core score of 1541 indicate solid computational power. However, in this specific game and with this specific GPU, the CPU's role is largely to feed data to a graphics processor that cannot keep up.

The measured FPS data shows that the CPU is not the bottleneck in this configuration. If the CPU were the limiting factor, we would expect to see similar frame rates across different resolutions, as the CPU's workload (physics, game logic, draw calls) remains relatively constant regardless of resolution. Instead, we see a significant drop in FPS as resolution increases, which is the signature of a GPU bottleneck. For example, at "Low" settings, the FPS drops from 50 at 1080p to 41 at 1440p and 30 at 4K. This scaling pattern proves that the GPU is saturated and is the primary limiter of performance.

The Ryzen 5 5600X, with its 32 MB of L3 cache and high single-thread performance (evidenced by a Cinebench R23 single-core score of 1541), is more than sufficient to handle the simulation's CPU-intensive tasks at these low frame rates. The CPU is effectively "waiting" for the GPU to finish rendering each frame. While a more powerful GPU would allow the Ryzen 5 5600X to flex its muscles and produce higher frame rates, in this pairing, its performance is capped by the Intel Arc B370. The data shows that the CPU's robust multi-threading capabilities, which score 11838 in Cinebench R23, are not being fully utilized because the GPU is unable to process frames quickly enough to create a CPU bottleneck.
