Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title, and the combination of the Intel Core i7-12700K and Intel Arc B390 produces a very specific performance profile. The measured data shows a system that is heavily constrained by its graphics processor, particularly at higher resolutions and settings. This analysis breaks down the benchmark results to explain what the numbers mean for playability and how the two primary components interact within this specific flight simulator.

How This Combo Ranks

Within the extensive database of tested hardware combinations for Microsoft Flight Simulator, this specific pairing of the Intel Core i7-12700K and Intel Arc B390 lands at rank 2665 out of 2996 tested combos. This places the combination in the lower percentile of all tested systems, indicating that its overall performance is on the lower end of the spectrum for this particular game. The rank suggests that while the CPU is a capable performer, the GPU is a significant limiting factor that prevents the system from achieving higher frame rates in this simulation.

The data shows this is not a high-performance gaming combo for this title. With a rank in the bottom 10% of all tested systems, the experience will be characterized by low frame rates, especially when compared to more balanced or higher-end configurations. The rank serves as a summary statistic: the system will run the game, but its performance is far from the top tier, and users should temper their expectations regarding smoothness and visual fidelity. The position of 2665 out of 2996 is a clear indicator that this pairing is not optimized for Microsoft Flight Simulator's high demands.

Resolution Scaling

The measured FPS data reveals a clear and predictable pattern of performance degradation as resolution increases. At 1920x1080 with Low settings, the system achieves an average of 56 FPS. This is the highest average frame rate recorded across all tested configurations. Moving to 2560x1440 at the same Low settings, the average FPS drops to 45, a noticeable decrease. At 3840x2160 with Low settings, the average falls further to 33 FPS.

This scaling pattern is a classic indicator of a GPU-bound scenario. The frame rate drops consistently as the pixel count increases because the Intel Arc B390 is tasked with rendering more pixels. The performance hit from 1080p to 4K at Low settings is a 41% reduction in average frame rate, from 56 to 33 FPS. This significant drop highlights that the graphics card's rendering capabilities are the primary constraint. The CPU, with its 12 cores and 20 threads, is likely not the bottleneck at these settings; instead, it is the GPU's fill rate and shader processing power that limit performance.

The trend continues across all settings. For instance, at Medium settings, the average FPS drops from 43 at 1080p to 35 at 1440p and finally to 26 at 4K. This consistent scaling across different quality presets reinforces the conclusion that the Intel Arc B390 is the limiting component. The data shows a system where the CPU has ample headroom, but the GPU struggles to keep up with the increasing resolution, making the graphics card the definitive bottleneck in this pairing.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture. Its performance in Microsoft Flight Simulator, as measured here, is low. The GPU's benchmark score in 3DMark Steel Nomad DX12 is 1482, placing it in the 9th percentile of all GPUs. This positions it near the bottom of the performance chart, directly alongside older, entry-level dedicated graphics cards. The data indicates that this GPU is not designed for high-end gaming, and its performance in a demanding simulator like this one is understandably limited.

The GPU's specifications reflect its integrated nature. It has a base clock of 300 MHz and a boost clock of 2500 MHz, with 1536 shading units. A key characteristic is its memory configuration: it uses "System Shared" memory, meaning it relies on the system's main RAM rather than dedicated VRAM. Its bandwidth is also listed as "System Dependent," which can introduce performance variability. In a game like Microsoft Flight Simulator, which can be sensitive to memory bandwidth, this shared memory setup is a likely contributor to the low frame rates observed, as the GPU must compete with the CPU for memory access.

The results show a direct correlation between the GPU's limited capabilities and the game's performance. The low average frame rates, even at 1080p, are a direct consequence of the Arc B390's low pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s. These figures are modest, and the data confirms that the GPU is the primary factor holding back the entire system's performance in this title. The 9th percentile ranking is a stark indicator of its position in the market, and the measured FPS data is consistent with that ranking.

Settings Recommendations

Based on the measured FPS data, the optimal balance between visual quality and playability is achieved at 1920x1080 with Low settings. This configuration yields an average frame rate of 56 FPS, which is the only setting that approaches a smooth, playable experience. While Low settings will reduce visual fidelity, the data shows that this is the most viable option for achieving a responsive frame rate with this hardware combination.

At 1080p, increasing the quality preset leads to a significant drop in performance. Medium settings average 43 FPS, High settings average 33 FPS, and Ultra settings average 31 FPS. While 43 FPS at Medium might be tolerable for some, the step from Low to Medium represents a 23% performance loss. The data suggests that for a consistently playable experience, Low settings are necessary. The frame rates at High and Ultra are below 35 FPS, which is generally considered the threshold for a smooth simulation experience.

For users with a 1440p or 4K display, the situation is more challenging. At 2560x1440, even Low settings only produce an average of 45 FPS. At 3840x2160, the average FPS at Low settings falls to 33, and at Medium settings, it's just 26 FPS. The data indicates that this combination of CPU and GPU is not suitable for high-resolution gaming in Microsoft Flight Simulator. These higher resolutions should be avoided unless the user is prepared to accept very low frame rates that will compromise the simulation's fluidity.

CPU Role

The Intel Core i7-12700K is a high-performance desktop processor from Intel's 12th Gen series, built on the Alder Lake architecture. It features 12 cores and 20 threads with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its benchmark results are strong, with a Cinebench R23 multi-core score of 19784 and a single-core score of 1850.5. These scores place the CPU in the 84th percentile of all CPUs, with an average benchmark score of 35287. This data confirms that the CPU is a powerful component, more than capable of handling the complex calculations required by a flight simulator.

In this specific test, the CPU's role is to feed the GPU with data. The strong multi-threaded performance, evidenced by a Passmark multithread score of 34404, ensures that the simulation's physics and AI logic are not a bottleneck. However, the measured FPS data shows that the system's performance is limited by the GPU, not the CPU. The frame rates at 1080p Low (56 FPS) are the highest measured, but they are still not exceptionally high, indicating that even when the GPU's load is relatively low, the overall performance is still constrained.

The CPU's 25 MB of shared L3 cache and support for both DDR4 and DDR5 memory provide a solid foundation, but these advantages are not fully realized in this game due to the GPU's limitations. The data shows a system with a significant performance imbalance: a top-tier CPU paired with an entry-level integrated GPU. The CPU is prepared to deliver high frame rates, but the Intel Arc B390 cannot keep up, making the CPU's potential largely untapped in this demanding gaming scenario.
