Microsoft Flight Simulator

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3070 delivers a decidedly mixed experience in Microsoft Flight Simulator, heavily dependent on the chosen resolution and quality preset. The data shows a system that is fully capable of smooth, playable frame rates at 1080p and 1440p, but one that requires significant setting compromises at 4K to stay above the 60 FPS threshold. The combination ranks in the 1608th position out of 3714 tested combos, placing it in the upper-middle tier of the database, which aligns with its measured performance profile.

Measured FPS Breakdown

At 1920x1080, the i5-12400F and RTX 3070 combination produces its strongest results, with the average frame rate scaling predictably with preset quality. The Low preset yields an average of 133 FPS, which is the highest score recorded for this combo across all resolutions and settings. Moving to Medium, the average drops to 108.7 FPS, still a substantial margin above the playability threshold. The High preset delivers an average of 78 FPS, and even the most demanding Ultra preset maintains a solid 75 FPS average. This resolution shows a consistent performance curve where the gap between presets is meaningful but not drastic, with the spread from Low to Ultra being 58 FPS.

At 2560x1440, the performance remains robust but begins to show the increased load. The Low preset average is 110.2 FPS, a notable 22.8 FPS drop from its 1080p counterpart. Medium follows at 85.6 FPS, while High achieves an average of 65.9 FPS. The Ultra preset is the first to dip near the critical threshold, recording an average of 59.9 FPS, a hair below the 60 FPS target. The scaling from 1080p to 1440p is roughly a 17-20% performance reduction across most presets, indicating that the GPU is beginning to become a more significant factor, though the CPU still carries its weight.

At 3840x2160, the picture changes dramatically. The Low preset average is 78.5 FPS, which is still playable but represents a 41% reduction from the 1080p Low score. Medium drops to an average of 61 FPS, just barely clearing the playable bar. High falls to 47.1 FPS, and Ultra bottoms out at 43.9 FPS. This resolution exposes the RTX 3070’s limits, as the 8 GB GDDR6 memory buffer and 448.0 GB/s bandwidth struggle to feed the massive pixel count. The performance cliff between Medium and High at 4K is steep, with a 13.9 FPS difference, highlighting that the higher presets are not viable at this resolution.

CPU and GPU Roles

The benchmark results indicate a clear shift in component bottleneck depending on the resolution. At 1920x1080, the data suggests that the CPU is the primary limiter. The i5-12400F, with its 6 cores and 12 threads, posts a Cinebench R23 multicore score of 12380 and a single-core score of 1680, which are respectable but not exceptional for a modern desktop processor. The frame rate differences between Medium (108.7 FPS), High (78 FPS), and Ultra (75 FPS) are relatively small, suggesting that the GPU has headroom to render more frames, but the CPU cannot feed it data fast enough to push the average higher. This is typical for a flight simulator, which does not scale perfectly with many cores.

At 2560x1440, the balance shifts towards the GPU. The performance drop from 1080p is substantial, and the gap between Medium (85.6 FPS) and High (65.9 FPS) widens, indicating that the rendering workload is now more significant. The CPU is still capable, but the GPU’s 5888 shading units and 184 texture mapping units are being tasked more heavily. The fact that Ultra at 1440p (59.9 FPS) falls below 60 FPS, while High (65.9 FPS) stays above it, shows that the extra load from Ultra settings (likely higher draw distances and shadow quality) pushes the GPU past its comfort zone.

At 3840x2160, the GPU is unambiguously the dominant bottleneck. The RTX 3070’s 256-bit memory bus and 8 GB frame buffer are insufficient for the sheer data throughput required at this resolution. The difference between Low (78.5 FPS) and Medium (61 FPS) is 17.5 FPS, but the gap between Medium and High (47.1 FPS) is 13.9 FPS, and High to Ultra (43.9 FPS) is only 3.2 FPS. This pattern indicates that once the GPU’s compute and memory resources are exhausted, further preset increases yield diminishing returns, and the frame rate collapses. The CPU’s role at this resolution is minimal, as it is likely waiting on the GPU for most of the frame time.

Best Settings per Resolution

For 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average frame rate of 75 FPS. This is the clear best choice for a 1080p monitor, as it provides the highest visual fidelity without sacrificing smoothness. The i5-12400F and RTX 3070 have ample headroom at this resolution, and the data shows no reason to drop below Ultra.

At 2560x1440, the best settings are High, which achieves an average of 65.9 FPS. While Medium (85.6 FPS) offers a higher frame rate, High provides a superior visual experience and still clears the 60 FPS threshold with a comfortable margin. Ultra is not viable, as its 59.9 FPS average falls just short of the target. Users with 1440p panels should select High to balance visual quality and performance.

At 3840x2160, the best playable setting is Medium, with an average of 61 FPS. This is a razor-thin margin above the 60 FPS threshold, and the data suggests that any in-game variance could cause dips below it. Low (78.5 FPS) is the safer choice for consistent performance, but Medium is technically playable. High (47.1 FPS) and Ultra (43.9 FPS) are not acceptable for smooth gameplay, as their averages fall well below the playable mark.

How This Combo Ranks

The combo rank of 1608 out of 3714 tested combinations places this system in the 43rd percentile of all tested hardware pairings. This ranking is consistent with its measured performance, which is strong at mainstream resolutions but falls off at 4K. The i5-12400F has a percentile of 73 among all CPUs, indicating it is a solid mid-range processor, while the RTX 3070 has a percentile of 61 among all GPUs, reflecting its position as a capable but not top-tier graphics card. The disparity between these percentiles explains the system’s behavior: the CPU is relatively stronger than the GPU, which is why the GPU becomes the limiting factor at higher resolutions.

This rank means that the combination is outclassed by roughly 57% of the other tested configurations. However, it is important to note that many of those higher-ranked combos likely feature significantly more expensive hardware, such as top-end CPUs and flagship GPUs. Within the context of its price class, the i5-12400F and RTX 3070 deliver competitive performance, particularly at 1080p and 1440p, where it outperforms many systems that may have more powerful GPUs but weaker CPUs.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-12400F, based on average benchmark scores, include the AMD Ryzen 5 7535HS with a delta of 0%, the Intel Core 3 201E with a delta of -0.1%, the Intel Core i5-1335U with a delta of 0.3%, and the AMD EPYC 7773X with a delta of 0.3%. These processors all have average scores within a fraction of a percent of the i5-12400F, meaning that in a gaming scenario like Microsoft Flight Simulator, they would likely produce very similar frame rates when paired with the same GPU. The Ryzen 5 7535HS is a mobile chip, but its performance parity suggests that a laptop with this CPU and an RTX 3070 would behave nearly identically to this desktop setup.

For the NVIDIA GeForce RTX 3070, the closest rivals are the AMD Radeon RX 7600 XT with a delta of 0.7%, the NVIDIA GeForce GTX 690 with a delta of 1%, and the AMD Radeon HD 7970M with a delta of 1.1%. The RX 7600 XT is the most relevant modern alternative, and its near-identical average score indicates that a system with an i5-12400F and an RX 7600 XT would deliver almost exactly the same FPS in this game. The GTX 690 and HD 7970M are older, multi-GPU or mobile solutions, but their scores suggest that they would also fall within a similar performance envelope, though their driver support and feature sets would be less capable for a modern title like Microsoft Flight Simulator.

The Verdict

Yes, this PC can run Microsoft Flight Simulator, but the experience is highly dependent on resolution and settings. At 1920x1080, the system clears the 60 FPS threshold at every preset, including Ultra, and is an excellent choice for high-refresh-rate monitors. At 2560x1440, it is playable at High settings with an average of 65.9 FPS, but Ultra is just below the mark at 59.9 FPS. At 3840x2160, the system is only playable at Low (78.5 FPS) and Medium (61 FPS) presets, with High and Ultra falling into the 40s FPS range. The data shows that the RTX 3070 is the limiting factor at 4K, while the i5-12400F provides ample CPU performance for this title. For the best balance of visual quality and smoothness, users should target High at 1440p, and they should not expect to run Ultra at 4K without significant frame rate sacrifices.
