Microsoft Flight Simulator

The Intel Core i5-12400 and NVIDIA GeForce RTX 3050 4 GB combination delivers a narrow performance window in Microsoft Flight Simulator, with the data revealing a system that is heavily constrained by its graphics card at higher resolutions and settings. The measured frames per second (FPS) across the twelve tested configurations show a clear hierarchy: the combo ranks 1625th out of 1795 tested combinations, placing it in the lower percentile of systems, which suggests that while it can run the sim, it does so with significant compromises. This analysis breaks down the measured results, examining how resolution and settings dictate the experience, what the hardware components contribute, and where the bottlenecks truly lie.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, revealing a GPU-bound scenario. At Low settings, the average frame rate falls from 72.3 FPS at 1920x1080 to 59.1 FPS at 2560x1440, a reduction of 13.2 FPS, and then plummets to 42.5 FPS at 3840x2160. This represents a total loss of 29.8 FPS, or roughly 41% of the 1080p performance, when moving to 4K. The pattern intensifies at higher presets; for instance, at High settings, the drop from 1080p to 4K is from 39.7 FPS down to 23.1 FPS, a 16.6 FPS loss. The data indicates that the RTX 3050's 4 GB frame buffer and 192.0 GB/s memory bandwidth are simply overwhelmed by the pixel count at 4K, making that resolution impractical for anything but the lowest preset.

The scaling behavior suggests that the limiting component is the GPU, not the CPU. The i5-12400, with its 6 cores and 12 threads, maintains a consistent baseline, but the FPS collapse at 4K is characteristic of a graphics card hitting its memory and compute ceiling. When moving from 1440p to 4K at Medium settings, the frame rate drops from 44.9 FPS to 35.1 FPS, a 9.8 FPS decline. This is a larger absolute drop than the 5.3 FPS decline seen when moving from 1080p to 1440p at the same settings, indicating that the cost of each additional pixel grows disproportionately as the resolution increases, further confirming the GPU as the primary bottleneck. The CPU's role becomes more apparent at lower resolutions, where the GPU is less saturated, but the measured data shows that even at 1080p Low, the system only reaches 72.3 FPS, suggesting the CPU is not the limiting factor even in the least demanding scenario.

Settings Recommendations

The measured rows point to a simple truth: the "Low" preset is the only configuration that provides a consistently playable experience across all resolutions. At 1920x1080, Low yields 72.3 FPS, which is comfortably above the threshold for smooth simulation. At 2560x1440, Low still manages 59.1 FPS, a playable figure, while the "Medium" preset drops to 44.9 FPS, which may be acceptable but is noticeably less fluid. At 4K, only Low achieves a playable frame rate of 42.5 FPS; every other preset falls below 35.1 FPS, with Ultra bottoming out at 20.6 FPS.

For a balance of visual fidelity and performance, the data suggests that 1080p Medium is the optimal choice, offering 53.8 FPS. This provides a meaningful improvement over Low (72.3 FPS) in graphical quality while maintaining a frame rate that is still responsive. However, if the user prioritizes frame rate stability above all else, 1080p Low is the only setting that approaches the 60 FPS mark. The "High" and "Ultra" presets are not viable for this combo in Microsoft Flight Simulator, as they yield 39.7 FPS and 42.6 FPS at 1080p, respectively, which are below the 60 FPS target and will result in noticeable stutter during scenery-heavy flights. The data clearly implies that this hardware is best suited for 1080p gaming with moderate settings, and any attempt to push beyond that requires a significant sacrifice in visual quality.

How This Combo Ranks

The combo's rank of 1625 out of 1795 tested combinations places it in the bottom 9.5% of all systems tested, which is a poor showing for a modern setup. This low ranking is primarily attributed to the GPU's performance, as the RTX 3050's percentile vs all GPUs is 50, meaning it sits at the median of all graphics cards, but the combination's overall score is dragged down by the game's demanding nature. The Intel Core i5-12400, in contrast, holds a percentile of 77 vs all CPUs, indicating a solid mid-range processor, but it cannot compensate for the GPU's limitations in this specific title.

When examining the CPU's nearest rivals, the i5-12400's average benchmark score of 19850 is nearly identical to the Intel Core i7-9700 (19831, deltaPct 0.1) and the Intel Core i7-8700 (19894, deltaPct -0.2). This indicates that the processor's computational power is on par with older high-end chips, and it is not a weak link in the system. However, the GPU's lack of a comparable benchmark score in the fact pack, combined with its 4 GB memory limit, places the entire combo in a low tier for this flight simulator. The ranking implies that for the same CPU, pairing it with a more powerful GPU would yield significantly better results, while upgrading the CPU alone would offer minimal gains given the current GPU bottleneck. The data suggests the i5-12400 is capable of feeding a stronger graphics card, but the RTX 3050 4 GB holds the system back.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the system's performance envelope. At 1920x1080, the results are as follows: Low averages 72.3 FPS, Medium averages 53.8 FPS, High averages 39.7 FPS, and Ultra averages 42.6 FPS. It is notable that Ultra performs slightly better than High at this resolution, which is an anomaly in the data, possibly indicating a variance in the test scenario or a driver quirk. At 2560x1440, the averages are: Low at 59.1 FPS, Medium at 44.9 FPS, High at 33.2 FPS, and Ultra at 32.2 FPS. The gap between High and Ultra narrows at this resolution, with only a 1.0 FPS difference.

At 3840x2160, the system struggles significantly. Low averages 42.5 FPS, Medium averages 35.1 FPS, High averages 23.1 FPS, and Ultra averages 20.6 FPS. The scaling from 1440p to 4K at High settings shows a drop from 33.2 FPS to 23.1 FPS, a 10.1 FPS decline, which is a 30% reduction in performance. The data reveals a consistent pattern: the gap between Low and Medium is significant at all resolutions (18.5 FPS at 1080p, 14.2 FPS at 1440p, 7.4 FPS at 4K), while the gap between High and Ultra is minimal (2.9 FPS at 1080p, 1.0 FPS at 1440p, 2.5 FPS at 4K). This suggests that the Ultra preset offers little benefit over High for this hardware, while the Medium preset provides a substantial improvement over Low in visual quality with a moderate FPS cost.

GPU Role

The NVIDIA GeForce RTX 3050 4 GB is the dominant bottleneck in this configuration. Its 4 GB of GDDR6 memory on a 128-bit bus provides a bandwidth of 192.0 GB/s, which is insufficient for the high-resolution textures and large draw distances in Microsoft Flight Simulator. The GPU's boost clock of 1740 MHz and base clock of 1545 MHz are standard for the Ampere architecture, but the 2048 shading units are tasked with rendering complex scenes that quickly exhaust the memory buffer. The data shows that the FPS drops most sharply when moving to 4K, which aligns with the memory capacity being exceeded, forcing the system to use slower system memory.

The GPU's transistor count of 8,700 million and die size of 200 mm² on an 8 nm process from Samsung underscore its position as an entry-level part in the GeForce 30-series. The pixel rate of 55.68 GPixel/s and texture rate of 111.4 GTexel/s are modest, and the FP32 performance of 7.127 TFLOPS is adequate for 1080p gaming but not for higher resolutions. The data implies that the 4 GB memory size is the critical flaw for this game; even at 1080p Ultra, the system only achieves 42.6 FPS, which is below the 60 FPS target. The GPU's end-of-life production status also suggests that it is not a forward-looking investment for demanding titles like this. The results indicate that the RTX 3050 is a capable 1080p entry-level card for less demanding games, but it is out of its depth in Flight Simulator beyond Low settings.

CPU Role

The Intel Core i5-12400 plays a supportive but secondary role in this combo. With 6 cores and 12 threads, a base clock of 2.50 GHz and a boost clock of 4.40 GHz, it provides ample processing power for the simulation's physics and AI calculations. The CPU's cache hierarchy, featuring an 18 MB shared L3 cache and 1.25 MB per-core L2 cache, is well-suited for the game's data-heavy workloads. Its performance in benchmarks is strong, with a Cinebench R23 multi-core score of 15935 and a single-core score of 2249, placing it in the 77th percentile of all CPUs.

The data suggests the CPU is not the limiting factor in this system. The FPS does not scale with CPU clock speed in the measured results; instead, it drops with resolution, which is a GPU characteristic. For instance, the move from 1080p Low (72.3 FPS) to 1440p Low (59.1 FPS) is a 13.2 FPS drop, which cannot be attributed to the CPU, as its workload remains constant. The i5-12400's performance is nearly identical to the Intel Core i7-9700 (deltaPct 0.1) and the Intel Core i7-8700 (deltaPct -0.2), both of which are older CPUs, showing that the 12th-generation architecture provides no meaningful advantage in this game's GPU-bound scenarios. The CPU's role is to ensure that the GPU is fed with data, and with a 3dmark single-thread score of 910 and a passmark single-thread score of 3456, it does so effectively. The system's low overall rank is not a reflection of the CPU's capability but rather the GPU's inability to keep pace, implying that the i5-12400 is a solid foundation for a future GPU upgrade.

FAQ

Q: What is the best resolution for this combo to achieve a playable frame rate?

A: The data shows that 1920x1080 is the only resolution where the system can exceed 60 FPS, achieving 72.3 FPS at Low settings. At 2560x1440, the maximum average FPS is 59.1 at Low, which is just below the 60 FPS threshold. At 3840x2160, the highest average FPS is 42.5 at Low, which is not ideal for smooth gameplay.

Q: Why does the Ultra preset perform worse than High at 1080p?

A: At 1920x1080, the Ultra preset averages 42.6 FPS, while High averages 39.7 FPS, meaning Ultra is actually 2.9 FPS faster. This is an anomaly in the measured data, likely due to a variation in the test scenario or a driver-specific optimization, but it is not a consistent trend, as Ultra is slower than High at both 1440p and 4K.

Q: How does the CPU's performance compare to its nearest rivals?

A: The Intel Core i5-12400 has an average benchmark score of 19850, which is nearly identical to the Intel Core i7-9700 (19831, deltaPct 0.1) and the Intel Core i7-8700 (19894, deltaPct -0.2). This indicates that the i5-12400 offers similar computational power to these older Intel chips, but it does not translate to better FPS in this game due to the GPU bottleneck.

Q: Is the 4 GB of VRAM sufficient for Microsoft Flight Simulator?

A: The measured FPS data suggests that 4 GB is not sufficient for higher settings. At 3840x2160, all presets except Low fall below 35.1 FPS, and at 2560x1440, the Ultra preset drops to 32.2 FPS. The VRAM capacity appears to be a limiting factor, as the frame rate drops steeply when the resolution increases, indicating the memory buffer is being exhausted.

Q: What is the impact of the GPU's memory bandwidth on the game's performance?

A: The GPU has a memory bandwidth of 192.0 GB/s, which is a key constraint. The data shows a consistent FPS drop when moving from 1440p to 4K; for example, at Medium settings, the FPS falls from 44.9 to 35.1. This suggests that the bandwidth is insufficient to handle the increased data transfer required at higher resolutions, contributing to the overall GPU bottleneck.

Q: Does the CPU's core count affect the FPS in this game?

A: The CPU has 6 cores and 12 threads, which is sufficient to avoid being a bottleneck. The FPS scales almost entirely with resolution and settings, not with CPU load. Since the FPS drops by roughly 41% from 1080p to 4K at Low settings, it is clear that the GPU is the limiting component, and the CPU's core count does not directly improve or hinder the measured frame rates.
