Microsoft Flight Simulator

The Intel Core i3-12100F is a 4-core, 8-thread desktop processor based on Alder Lake, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. For a flight simulator like Microsoft Flight Simulator, the single-thread performance is often the dominant factor, as the simulation’s core logic—world rendering, physics, and AI traffic—typically scales heavily on one or two threads. The benchmark data for this CPU shows a 3DMark single-thread score of 893, while the 4-thread score is 2859 and the 8-thread score is 4026. The jump from 4 to 8 threads is only about 40%, indicating that the processor’s performance does not scale linearly with additional threads beyond its physical core count. In the context of this game, the CPU’s multi-threaded capacity (a Cinebench R23 multi-core score of 11912) is adequate for background tasks, but the higher boost clock is what will keep the main simulation thread fed.

The CPU’s 12 MB of shared L3 cache and dual-channel memory support (DDR4 and DDR5) are relevant, but the game’s frame rate at high settings is more likely to be determined by how well the 12100F can maintain its boost clock under load. When compared to its nearest rivals in the CPU benchmark database, the Core i3-12100F sits in the 72nd percentile of all CPUs. The data shows it is essentially neck-and-neck with the AMD Ryzen Threadripper PRO 3975WX, trailing by only 0.1%, and it is 0.6% ahead of the Intel Core i3-10105. This is a strong showing for a 4-core part, but in Microsoft Flight Simulator, the CPU’s role is to avoid becoming a bottleneck at lower resolutions; at higher resolutions, the GPU takes over the heavy lifting.

GPU Role

The NVIDIA GeForce RTX 3080 is the primary driver of visual fidelity in this configuration. It comes with 10 GB of GDDR6X memory on a 320-bit bus, delivering a bandwidth of 760.3 GB/s. The GPU’s base clock is 1440 MHz with a boost clock of 1710 MHz, and it features 8704 shading units. For a game like Microsoft Flight Simulator, which streams vast amounts of terrain and scenery data, the memory bandwidth and VRAM capacity are critical. The 10 GB frame buffer is sufficient for the Ultra preset at 1080p and 1440p, but at 4K, the data suggests the GPU is working harder to manage texture loads and geometry.

The RTX 3080’s raw compute is high, with an FP32 rating of 29.77 TFLOPS, placing it in the 80th percentile of all GPUs. In the benchmark database, its closest rival is the AMD Radeon Pro Duo, which is only 0.2% faster, and it leads the AMD Radeon 880M by 0.4%. This indicates the RTX 3080 is a mature, high-end part, though it is now marked as end-of-life. In Microsoft Flight Simulator, the GPU’s role becomes more pronounced as resolution increases. The measured FPS data shows that at 1080p with Ultra settings, the average FPS is 88, which is only slightly lower than the 92 FPS at High settings. This suggests that even at 1080p, the GPU is not fully maxed out, and the CPU’s 4-core architecture may be starting to limit the frame rate at lower resolutions. However, at 4K Ultra, the GPU’s load increases significantly, and the frame rate drops accordingly.

Settings Recommendations

The measured FPS data provides a clear picture of how this combo behaves across different presets. At 1080p, the Low preset yields an average of 156.7 FPS, which is far above playable levels, but the jump to Medium drops it to 125.4 FPS. The High preset at 1080p gives 92 FPS, and Ultra drops to 88 FPS. The difference between High and Ultra at 1080p is only 4 FPS, which is negligible for a flight simulator where smoothness matters more than a few extra frames. Given that the game is a simulation, the recommendation is to use the High preset at 1080p, as it provides the best balance between visual quality and performance without taxing the system unnecessarily.

At 1440p, the High preset achieves 75.2 FPS, while Ultra drops to 70.8 FPS. The gap between Medium (96.1 FPS) and High is larger, but the visual improvement from High to Ultra is minimal in this game. The data suggests that High is the sweet spot at 1440p, as it maintains a frame rate above 70 FPS while keeping the GPU load reasonable. At 4K, the situation changes: the High preset yields 52.5 FPS, which is playable but not ideal for a smooth experience. The Low preset at 4K gives 95.1 FPS, but that sacrifices too much visual detail. The Medium preset at 4K offers 70.7 FPS, which is a better compromise. For the best experience per the measured rows, the High preset at 1080p or 1440p is recommended, as it avoids the steep performance penalty of Ultra while delivering nearly identical frame rates.

How This Combo Ranks

The combination of the Intel Core i3-12100F and NVIDIA GeForce RTX 3080 ranks 528th out of 1795 tested combos in Microsoft Flight Simulator. This places it in the top 30% of all configurations tested, which is a solid result given the CPU’s budget-oriented 4-core design paired with a high-end GPU. The rank indicates that the combo is well-balanced for this game, but it is not at the absolute top tier. The data shows that the CPU’s single-thread performance is sufficient to keep up with the RTX 3080 at most settings, but the 4-core limitation becomes apparent at lower resolutions where the GPU is less of a bottleneck.

Compared to other combos, this pairing is likely outperformed by systems with higher-core-count CPUs, but the RTX 3080’s strong showing in the GPU benchmarks (80th percentile) helps to compensate. The rank of 528 out of 1795 suggests that this is a capable setup for flight simulation, but not a top-100 build. For a builder looking to maximize frame rates in this specific game, the data implies that the CPU is the limiting factor at 1080p, while the GPU is the limiting factor at 4K. This is a classic mid-range CPU with a high-end GPU pairing, and the rank reflects that trade-off.

Resolution Scaling

The measured FPS data shows how performance scales as resolution increases from 1080p to 4K. At the Low preset, the average FPS drops from 156.7 at 1080p to 127.9 at 1440p, and then to 95.1 at 4K. This represents a 39% drop from 1080p to 4K, which is a significant reduction. At the High preset, the drop is from 92 FPS at 1080p to 75.2 FPS at 1440p, and then to 52.5 FPS at 4K—a 43% drop. The Ultra preset shows a similar trend: 88 FPS at 1080p, 70.8 FPS at 1440p, and 53.1 FPS at 4K, a 40% drop.

These scaling patterns indicate that the GPU is the primary limiting component at higher resolutions. The fact that the drop from 1440p to 4K is larger than the drop from 1080p to 1440p suggests that the RTX 3080’s 10 GB VRAM and bandwidth are being pushed harder at 4K, especially on the High and Ultra presets. Conversely, the relatively small difference between High and Ultra at 1080p (92 vs 88 FPS) suggests that the CPU is not the bottleneck at that resolution; rather, the GPU is handling the load fine, and the frame rate is limited by the simulation’s single-threaded nature. The data shows that if you want to play at 4K, you should lower settings to Medium to stay above 70 FPS, while at 1080p, you can safely run Ultra without a major penalty.

Measured FPS Breakdown

At 1920x1080, the measured average FPS is 156.7 on Low, 125.4 on Medium, 92 on High, and 88 on Ultra. The step from Low to Medium is a 20% drop, while the step from High to Ultra is only 4.3%, showing diminishing returns on the highest preset. At 2560x1440, the averages are 127.9 on Low, 96.1 on Medium, 75.2 on High, and 70.8 on Ultra. The transition from 1080p to 1440p costs roughly 18-20% performance across all settings, which is expected for a resolution increase of 78% in pixel count.

At 3840x2160, the averages are 95.1 on Low, 70.7 on Medium, 52.5 on High, and 53.1 on Ultra. Notably, the Ultra preset at 4K (53.1 FPS) is actually slightly higher than High (52.5 FPS), which is a data anomaly but suggests the Ultra preset may be using different rendering paths that are better optimized for the RTX 3080. The gap between Medium and High at 4K is 34.7%, which is much steeper than at lower resolutions. This indicates that the High and Ultra presets are heavily taxing the GPU’s memory bandwidth at 4K, while the Medium preset provides a more comfortable load. For a smooth experience at 4K, the Medium preset is the only viable option above 60 FPS, while at 1440p, the High preset offers a solid 75 FPS for a playable experience.
