# Microsoft Flight Simulator: Intel Core i5-11400F + Intel Arc B570

The Intel Core i5-11400F paired with the Intel Arc B570 delivers a playable but demanding experience in Microsoft Flight Simulator, with performance scaling predictably across resolutions and quality presets. This combination ranks near the bottom quartile of tested configurations, suggesting it is best suited for 1080p or modest 1440p gameplay rather than high-resolution ultra settings. The data shows a clear pattern: frame rates drop sharply as resolution and quality increase, with the GPU emerging as the primary bottleneck at higher loads while the CPU holds its ground.

Resolution Scaling

The measured FPS data reveals a steep performance curve as resolution climbs from 1920x1080 to 3840x2160. At 1920x1080 with Low settings, the combo achieves 86 FPS average, which drops to 69 FPS at 2560x1440 and 51 FPS at 3840x2160 — a 41% reduction from 1080p to 4K at the same preset. This scaling is consistent with GPU-bound behavior, where pixel throughput becomes the deciding factor. The drop from 1080p to 1440p is 17 FPS, while the drop from 1440p to 4K is 18 FPS, indicating a near-linear degradation per pixel-count increase.

At High settings, the pattern repeats but with lower absolute numbers: 50 FPS at 1080p, 41 FPS at 1440p, and 30 FPS at 4K. The percentage loss from 1080p to 4K here is 40%, nearly identical to Low, which suggests the resolution scaling penalty is consistent regardless of quality preset. However, the absolute FPS at 4K High (30) falls below the commonly cited 60 FPS target, making it marginal for smooth flight simulation. The 4K Ultra preset bottoms out at 28 FPS, barely above a slideshow threshold for a genre that benefits from fluid camera movement.

The Medium preset offers the most complete dataset, with min and max FPS recorded at all three resolutions. At 1080p Medium, the average is 67 FPS with a min of 57 and max of 77. Moving to 1440p Medium, the average drops to 54 FPS with min/max of 46/62. At 4K Medium, the average falls to 40 FPS with min/max of 34/46. This data indicates that even the minimum frame rates remain above 30 FPS at 1080p and 1440p Medium, but 4K Medium dips to 34 FPS minimum, which could cause noticeable stutter during complex scenery loading.

What does this scaling say about the limiting component? The consistent ~40% drop from 1080p to 4K across presets points to the GPU as the primary constraint at higher resolutions. If the CPU were limiting, the scaling would flatten at higher resolutions since the CPU workload remains constant while GPU load increases. Instead, the linear degradation suggests the Intel Arc B570's 10 GB memory and 380.0 GB/s bandwidth are being saturated by the 4K framebuffer, a conclusion reinforced by the fact that the CPU's 6 cores and 12 threads are unlikely to bottleneck a flight simulator that is traditionally GPU-heavy at high pixel counts.

GPU Role

The Intel Arc B570 is built on the Xe2-HPG architecture (Battlemage generation) using a 5 nm TSMC process. Its base and boost clocks are both 2500 MHz, which is modest for a modern GPU but consistent with its 150 W TDP. The memory configuration includes 10 GB of GDDR6 on a 160-bit bus, yielding 380.0 GB/s of bandwidth — a figure that is adequate for 1080p but becomes strained at 4K, where the measured FPS drops below 40 at every preset except Low.

The GPU's benchmark scores place it at the 65th percentile among all GPUs, with an average benchmark score of 20556. Its nearest rivals in the data include the NVIDIA GeForce RTX 3070 Mobile (avgScore 20534, deltaPct 0.1), the Intel Arc A750 (avgScore 20582, deltaPct -0.1), and the NVIDIA Quadro M4000M (avgScore 20480, deltaPct 0.4). These deltas are all within 0.5%, meaning the Arc B570 performs essentially identically to those parts in synthetic benchmarks. However, in Microsoft Flight Simulator, the Arc B570's 11.52 TFLOPS FP32 throughput and 200.0 GPixel/s pixel rate translate to the observed frame rates, which are respectable for a mid-range card but far from flagship territory.

The 10 GB VRAM capacity is worth examining in the context of this game. Flight simulators are known for large texture sets and detailed terrain. At 4K Ultra, the measured 28 FPS suggests the GPU is both fill-rate limited and possibly memory-bandwidth limited. The 160-bit bus, while paired with fast GDDR6, delivers 380.0 GB/s, which is lower than many competing cards in the same performance tier. The Arc B570's 2304 shading units and 80 ROPs are adequate for 1080p and 1440p, where the data shows 86 FPS (1080p Low) and 69 FPS (1440p Low), but the 4K results indicate diminishing returns from the GPU's compute resources.

One notable observation is the absence of any frame rate advantage from the GPU's boost clock, which equals the base clock at 2500 MHz. This suggests the card runs at a fixed frequency under load, which simplifies thermal behavior but also means there is no dynamic overclocking headroom to compensate for demanding scenes. The data shows that at 1080p Ultra, the combo still manages 48 FPS, which is only 2 FPS below the 4K Low result (51 FPS) — an interesting crossover that highlights how much resolution affects performance relative to quality settings.

How This Combo Ranks

This specific CPU-GPU combination ranks 2406 out of 2996 tested combos in Microsoft Flight Simulator, placing it in the 20th percentile of all configurations. This is a low ranking that reflects the mid-range nature of both components. The CPU alone sits at the 71st percentile among all processors, while the GPU is at the 65th percentile among all GPUs, but their combination in this game yields a below-average result due to the demanding nature of flight simulation.

To contextualize the CPU's standing, its nearest rivals include the AMD EPYC 7H12 (avgScore 17120, deltaPct 0.3), the Intel Core i5-12450H (avgScore 17239, deltaPct -0.4), the AMD Ryzen 3 PRO 8300G (avgScore 17278, deltaPct -0.6), and the Intel Core Ultra 7 164U (avgScore 17074, deltaPct 0.6). These deltas are all within 1%, indicating that the i5-11400F performs nearly identically to these parts in average benchmark scores. The i5-11400F's average benchmark score is 17177, which is remarkably close to the EPYC 7H12's 17120 — a server-grade chip with far more cores. This suggests the i5-11400F's single-thread performance, as evidenced by its 3dmark_single_thread score of 868 and cinebench_r23_singlecore score of 2024, is competitive even at higher tiers.

For the GPU, the nearest rivals include the RTX 3070 Mobile (20534), Arc A750 (20582), Quadro M4000M (20480), and Radeon R9 M390X (20662). The Arc B570's avgBenchmarkScore of 20556 places it squarely between the RTX 3070 Mobile and the Arc A750, with deltas of 0.1% and -0.1% respectively. This means the B570 is essentially a peer of the RTX 3070 Mobile in synthetic tests, yet in Microsoft Flight Simulator, the combo's rank of 2406 suggests that either the game favors NVIDIA optimizations or the CPU-GPU pairing introduces inefficiencies not captured by isolated benchmark scores.

The rank of 2406 out of 2996 means that 590 combos perform worse, which is a small minority. This places the combo in the bottom 20%, a position that will require users to make compromises in settings or resolution to achieve acceptable frame rates. However, it is importantly the rank is not catastrophic — the combo still achieves 86 FPS at 1080p Low, which is highly playable, and the presence of measured data for all presets and resolutions indicates the system is stable across the board.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend heavily on the target resolution. At 1920x1080, the Medium preset offers the best balance of visual quality and performance, delivering 67 FPS average with a minimum of 57 FPS and maximum of 77 FPS. This is above the 60 FPS threshold, making it smooth for most flight simulation scenarios. The High preset at 1080p drops to 50 FPS, which is still playable but leaves less headroom for complex scenes, while Ultra at 48 FPS is borderline. The Low preset at 86 FPS is overkill for most users but could be useful for competitive or streaming scenarios.

At 2560x1440, the Medium preset again emerges as the recommended choice, with 54 FPS average and min/max of 46/62. This is slightly below the 60 FPS ideal but remains within a playable range. The Low preset at 69 FPS is the only 1440p option that consistently exceeds 60 FPS, making it the safe choice for demanding users. High at 41 FPS and Ultra at 39 FPS are both marginal, with the latter dipping below 40 FPS, which may cause noticeable judder during panning.

At 3840x2160, the situation becomes more challenging. The Low preset at 51 FPS is the only option that approaches playable territory, and even it falls short of 60 FPS. Medium at 40 FPS with a 34 FPS minimum is the best quality-to-performance trade-off, but users should expect occasional stutters. High at 30 FPS and Ultra at 28 FPS are essentially unsuitable for serious flight simulation, as the frame rates are too low for smooth interaction with cockpit instruments and terrain.

The data suggests that the Medium preset is the "sweet spot" for this combo across all resolutions, as it provides the most consistent frame pacing (evidenced by the narrow min-max range) while maintaining acceptable visual fidelity. For 1080p users, Medium is a clear recommendation. For 1440p users, Medium is acceptable with minor compromises. For 4K users, Low is the only viable option, and even then, the 51 FPS average may be too low for some. The Ultra preset should be avoided entirely, as it offers only a marginal visual improvement over High while costing 40-50% of the frame rate.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, manufactured on Intel's 14 nm process. Its base clock of 2.60 GHz boosts to 4.40 GHz, providing adequate single-thread performance for flight simulation, which historically relies heavily on single-core performance for flight dynamics and AI calculations. The CPU's 12 MB of shared L3 cache and 51.2 GB/s dual-channel DDR4 memory bandwidth are sufficient for this game, as the data shows the CPU is not the primary bottleneck at any resolution.

In synthetic benchmarks, the i5-11400F achieves a single-thread score of 868 in 3dmark_single_thread and 2024 in cinebench_r23_singlecore, both of which are respectable for a mid-range desktop CPU. Its multi-threaded performance, as measured by cinebench_r23_multicore at 14340, is strong for a 6-core part and places it at the 71st percentile among all CPUs. The CPU's nearest rivals in the benchmark database include the AMD EPYC 7H12 (a server chip with far more cores) and the Intel Core i5-12450H (a mobile part), yet the deltas are all under 1%, indicating that the i5-11400F holds its own across diverse workloads.

For Microsoft Flight Simulator specifically, the CPU's role is to handle game logic, physics, and AI, while the GPU renders the complex scenery. The measured FPS data shows that at 1080p Low, the combo achieves 86 FPS, which is close to the CPU's practical limit for this game given the GPU's capabilities. If the CPU were severely limiting, we would expect to see similar FPS at 4K Low as at 1080p Low, but the 4K Low result of 51 FPS is significantly lower, confirming that the GPU takes over as the limiting factor at higher resolutions.

The CPU's 65 W TDP and 14 nm process node are notable for their efficiency, especially when paired with a 150 W GPU in a system with a 450 W suggested PSU. The 6-core, 12-thread configuration is well-suited for modern games that utilize up to 8 threads, and the 4.40 GHz boost clock provides the high single-thread performance that flight simulators demand. However, the CPU's socket (Intel Socket 1200) and end-of-life production status mean that upgrade paths are limited, but for this specific combo, the i5-11400F provides a solid foundation that does not hold back the Arc B570 in most scenarios.
