Microsoft Flight Simulator

Settings Recommendations

The measured FPS rows for Microsoft Flight Simulator present a clear hierarchy across the four settings presets, and the data suggests that Medium is the optimal balance point for this combination of the Intel Core i5-10400F and the NVIDIA GeForce RTX 3050 4 GB. At 1080p, the Medium preset delivers 55.2 FPS, which is 13.8 FPS higher than High (41.4) and 12.4 FPS higher than Ultra (42.8). The jump from Low to Medium is meaningful—68.4 FPS to 55.2—but the visual fidelity gain from Low to Medium typically outweighs the 13.2 FPS loss in a flight simulator where scenery detail matters. Pushing to High or Ultra at 1080p yields diminishing returns, with Ultra only 1.4 FPS above High but requiring significantly more GPU resources.

At 1440p, Medium again stands out as the recommended preset. It achieves 46.7 FPS, which stays above the 30 FPS playability threshold for a slow-paced simulation, while High drops to 32.5 and Ultra to 34.4. The Low preset at 1440p hits 55.5 FPS, but the visual compromise is substantial. At 4K, no preset reaches 45 FPS—Medium manages 33.3, Low 43.9, High 23.2, and Ultra 21.3—so users targeting 4K must accept either Low settings or a sub-30 FPS experience. For the best experience per the measured rows, Medium at 1080p or 1440p is the sweet spot, with the 1440p Medium value of 46.7 FPS being particularly compelling for users with higher-resolution displays.

GPU Role

The RTX 3050 4 GB is the limiting factor in this pairing, and the VRAM capacity is the most telling specification. With only 4 GB of GDDR6 memory on a 128-bit bus delivering 192.0 GB/s of bandwidth, the card is constrained in a game like Microsoft Flight Simulator that streams vast amounts of terrain and aircraft data. The benchmark results corroborate this: at 4K Ultra, the average FPS collapses to 21.3, and even at 1080p Ultra it only reaches 42.8. The GPU's 2048 shading units, 64 TMUs, and 32 ROPs are modest by modern standards, and the 7.127 TFLOPS FP32 throughput is barely sufficient for high-fidelity flight simulation.

The clock behavior is another indicator. The GPU boosts to 1740 MHz from a 1545 MHz base, but the memory speed of 1500 MHz (12 Gbps effective) creates a bandwidth bottleneck when textures exceed the 4 GB frame buffer. The data shows that dropping from High to Low at 4K improves FPS from 23.2 to 43.9—a 20.7 FPS swing—which suggests that the card is swapping textures and struggling with memory pressure at higher presets. The pixel rate of 55.68 GPixel/s and texture rate of 111.4 GTexel/s are adequate for 1080p Medium but clearly insufficient for 4K Ultra. The GPU's percentileVsAllGpus of 50 places it exactly at the median, meaning half of all GPUs are faster, which aligns with the measured FPS being playable only at lower resolutions and presets.

CPU Role

The Intel Core i5-10400F provides a solid foundation with 6 cores and 12 threads, boosting from 2.90 GHz base to 4.30 GHz. Its benchmark scores are respectable: Cinebench R23 multi-core hits 10,297 and single-core 1,453, while Geekbench multi-core reaches 5,783 and single-core 1,454. The 3DMark results show scaling from 1,350 (2 threads) to 4,735 (max threads), indicating that the CPU can leverage its 12 threads effectively. For Microsoft Flight Simulator, which is known for heavy single-threaded simulation logic combined with multi-threaded asset streaming, this CPU's single-thread performance is adequate—the 3DMark single-thread score of 688 and PassMark single-thread of 2,541 are competitive.

However, the CPU is not the primary constraint in this combo's measured results. At 1080p Low, the FPS reaches 68.4, which is the highest measured value across all resolutions and settings, suggesting the CPU can feed the GPU at lower loads. The L3 cache of 12 MB shared across 6 cores is modest but sufficient, and the dual-channel DDR4 memory at 42.7 GB/s bandwidth provides enough throughput for the CPU's needs. The percentileVsAllCpus of 73 means the i5-10400F outperforms 73% of all CPUs, making it a capable partner—but the GPU's 4 GB VRAM and 192.0 GB/s bandwidth create the ceiling. The data implies that upgrading the GPU would yield larger FPS gains than upgrading this CPU, as the CPU's single-thread performance (Cinebench R20 single-core 610) is not the bottleneck in the measured scenarios.

How This Combo Ranks

This specific combination of the Intel Core i5-10400F and the NVIDIA GeForce RTX 3050 4 GB ranks 1626 out of 1795 combos in Microsoft Flight Simulator. That places it in the bottom 9.4% of tested configurations, which is a sobering statistic for a game with this title's visual ambitions. The rank is driven primarily by the GPU's limitations—a GPU at the 50th percentile paired with a CPU at the 73rd percentile. The CPU's nearest rivals show it is closely matched with the AMD EPYC 7552 (0.4% faster), AMD Ryzen 3 7320C (0.8% slower), Intel Core i5-8500 (1.1% slower), and AMD Ryzen Embedded V2546 (1.2% slower), but none of these CPU comparisons can overcome the GPU's 4 GB VRAM constraint.

The rank of 1626 out of 1795 implies that most other combinations tested achieve higher average FPS in this game. The data suggests that this combo is best suited for 1080p Medium gaming, where it achieves 55.2 FPS, or 1440p Medium at 46.7 FPS. For users with this exact hardware, the ranking indicates that expectations must be calibrated: this is not a high-fidelity system for Microsoft Flight Simulator, but it can deliver playable frame rates at moderate settings. The large gap between the combo's rank and the CPU's percentile (73) versus the GPU's percentile (50) reinforces that the GPU is the weak link.

FAQ

A: Medium delivers 55.2 FPS, which balances visual quality and performance. High (41.4) and Ultra (42.8) offer marginal fidelity gains but drop below 45 FPS, while Low (68.4) sacrifices too much detail.

Q: Can this combo handle 4K gaming in Microsoft Flight Simulator?

A: Not at high settings. The best 4K result is Low at 43.9 FPS, but Medium drops to 33.3, High to 23.2, and Ultra to 21.3. Only Low is consistently playable at 4K.

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

A: The i5-10400F is within 1.2% of the AMD EPYC 7552, AMD Ryzen 3 7320C, Intel Core i5-8500, and AMD Ryzen Embedded V2546 in average benchmark score, making it statistically equivalent to these processors.

Q: Is the GPU or CPU the limiting factor in this combo?

A: The GPU is the bottleneck. Its 4 GB VRAM and 192.0 GB/s bandwidth constrain performance, as shown by the 20.7 FPS difference between High and Low at 4K. The CPU's percentile rank of 73 versus the GPU's 50 confirms this.

Q: What FPS can I expect at 1440p Medium?

A: The measured average is 46.7 FPS, which is playable for a flight simulator. This is the best 1440p preset that stays above 40 FPS, with High (32.5) and Ultra (34.4) falling below that threshold.

Q: Does the RTX 3050 4 GB's 4 GB VRAM matter for this game?

A: Yes. The 4 GB capacity on a 128-bit bus creates memory pressure at higher presets, evidenced by the sharp FPS drops from Low to Medium at all resolutions—a 24.5 FPS difference at 4K and 13.2 FPS at 1080p.

Measured FPS Breakdown

At 1080p, the full range of presets is usable. Low achieves 68.4 FPS, Medium 55.2, High 41.4, and Ultra 42.8. The interesting anomaly is that Ultra slightly outperforms High by 1.4 FPS, which may indicate driver-level optimizations or measurement variance, but both are below 45 FPS. The spread from Low to Ultra is 25.6 FPS, with the largest single drop occurring between Medium and High (13.8 FPS).

At 1440p, the values compress downward. Low hits 55.5 FPS, Medium 46.7, High 32.5, and Ultra 34.4. Again, Ultra edges out High by 1.9 FPS, but both are firmly in the 30-35 FPS range. The gap between Low and Medium is 8.8 FPS, and between Medium and High it is 14.2 FPS, showing that the High preset is where the GPU starts to struggle.

At 4K, the numbers are challenging. Low reaches 43.9 FPS, Medium 33.3, High 23.2, and Ultra 21.3. The drop from Low to Medium is 10.6 FPS, and from Medium to High is 10.1 FPS. Ultra is only 1.9 FPS below High, indicating that the GPU has hit a hard performance floor where additional settings have minimal impact. The 4K Ultra value of 21.3 FPS is the lowest measured, and it is 21.9 FPS below the 1080p Medium result.

Resolution Scaling

The FPS degradation from 1080p to 4K reveals where the bottleneck lies. At Medium settings, the progression is 55.2 FPS (1080p) → 46.7 FPS (1440p) → 33.3 FPS (4K). That is a 15.4% drop from 1080p to 1440p and a 28.7% drop from 1440p to 4K. At Low settings, the progression is 68.4 → 55.5 → 43.9, representing drops of 18.9% and 20.9% respectively. The fact that even Low settings lose 24.5 FPS from 1080p to 4K indicates that the GPU's raw throughput is insufficient for 4K, not just its VRAM.

The scaling pattern points to the GPU as the primary limiter. If the CPU were the constraint, the FPS at 1080p Low (68.4) would be much closer to the 4K Low (43.9), but the 35.8% reduction shows the GPU struggling with pixel count. Conversely, the CPU's consistent single-thread performance can feed the GPU at lower resolutions, but at 4K the GPU cannot keep up. The data also reveals that the gap between Low and Ultra narrows as resolution increases: a 25.6 FPS gap at 1080p, 21.1 FPS at 1440p, and 22.6 FPS at 4K. This suggests that at higher resolutions, the GPU is so saturated that changing settings has less relative impact—the card is always working at its limit. The 4K Low result of 43.9 FPS is the only 4K value that approaches playability, and it requires accepting minimal visual detail in a game that is celebrated for its graphics.
