Microsoft Flight Simulator

Microsoft Flight Simulator remains one of the most demanding titles in the PC landscape, and the pairing of the AMD Ryzen 5 8400F with the NVIDIA GeForce RTX 3050 4 GB illustrates a classic bottleneck dynamic. The data shows a system that can achieve playable frame rates at lower resolutions and settings, but which is heavily constrained by its graphics card as resolution and visual fidelity increase. This analysis breaks down the measured performance across resolutions and settings, explains the CPU and GPU roles, and contextualizes the combo's rank among all tested configurations.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across every settings preset, confirming that the GPU becomes the dominant limiting factor at higher resolutions. At Low settings, the average frame rate falls from 71.8 FPS at 1920x1080 to 55.2 FPS at 2560x1440, a reduction of roughly 23%. Pushing further to 3840x2160 yields only 44 FPS, meaning the jump from 1440p to 4K costs another 20% of performance. This pattern is typical of a GPU-bound scenario where pixel throughput becomes the primary constraint.

The trend is even more pronounced at Medium settings, where the 1080p result is 56.5 FPS, dropping to 46.9 FPS at 1440p and then to 33.4 FPS at 4K. The gap between 1440p and 4K here is 13.5 FPS, a 29% loss, which is larger than the 1080p-to-1440p drop of 9.6 FPS. This accelerating decline indicates that the RTX 3050's memory bandwidth of 192.0 GB/s and 128-bit bus are increasingly overwhelmed as the pixel count rises. At High settings, the pattern repeats: 41.7 FPS at 1080p, 32.2 FPS at 1440p, and 23.1 FPS at 4K. The Ultra preset shows the same shape, with 39.6 FPS at 1080p, 30.8 FPS at 1440p, and 22.8 FPS at 4K.

Notably, the difference between High and Ultra settings is minimal at every resolution. At 1080p, High produces 41.7 FPS while Ultra yields 39.6 FPS, a margin of just 2.1 FPS. At 4K, the difference is only 0.3 FPS (23.1 versus 22.8). This suggests that the Ultra preset adds graphical features that tax the GPU heavily without a proportional visual return in this test scenario, or that the card is already so saturated that the extra load barely changes the outcome. The practical takeaway is that users should stick to High settings, as Ultra offers no meaningful frame rate advantage and likely stresses the 4 GB VRAM buffer further.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on TSMC's 4 nm process. Its base clock is 4.20 GHz with a boost clock of 4.70 GHz, and it carries 16 MB of shared L3 cache. In synthetic benchmarks, the chip scores 20,851 points in Cinebench R23 multicore and 2,943 points in single-core, placing it in the 82nd percentile of all CPUs. This is a strong mid-range part that is unlikely to hold back a graphics card like the RTX 3050, especially at higher resolutions where the GPU is the clear bottleneck.

The CPU's nearest rivals in the database include the AMD Ryzen 7 2700X, which scores 25,057 in average benchmark score, a delta of 0% versus the 8400F's 25,064. The Ryzen AI 5 PRO 340 scores 25,099 (a -0.1% delta), and the EPYC 9474F scores 25,103 (-0.2% delta). The Ryzen 5 7500F is slightly behind at 24,993, a delta of 0.3%. These numbers show that the 8400F is competitive with older and newer parts alike, but none of these comparisons suggest a CPU limitation in Microsoft Flight Simulator.

Given that the frame rates at 1080p Low reach 71.8 FPS, the CPU is clearly capable of feeding the GPU with enough data. The fact that performance scales down so dramatically with resolution indicates that the CPU is not the primary constraint—if it were, frame rates would remain flat across resolutions. The 8400F's 12 threads and high single-thread score of 2,943 in Cinebench R23 are more than sufficient for a flight simulator that relies on heavy physics and scenery streaming, but the data here shows the GPU running out of steam long before the CPU does.

GPU Role

The NVIDIA GeForce RTX 3050 4 GB is an Ampere-architecture part built on Samsung's 8 nm process, with 2,048 shading units, 64 TMUs, and 32 ROPs. Its base clock is 1545 MHz with a boost of 1740 MHz, and it features 4 GB of GDDR6 memory on a 128-bit bus, providing 192.0 GB/s of bandwidth. The card's TDP is 90 W, and it sits at the 50th percentile of all GPUs in the database, meaning it is an average performer overall.

The 4 GB VRAM is a critical weakness for Microsoft Flight Simulator, which is known for streaming large textures and terrain data. At 1080p Low, the card achieves 71.8 FPS, which is playable, but the frame rate collapses as settings rise. The gap between Low and Medium at 1080p is 15.3 FPS (71.8 to 56.5), and the gap between Medium and High is another 14.8 FPS (56.5 to 41.7). This suggests that the card's memory bandwidth and VRAM capacity are being exhausted quickly as texture quality and draw distances increase.

At 4K, the card is simply overwhelmed. Even at Low settings, it only manages 44 FPS, and at Ultra, it drops to 22.8 FPS—barely above slideshow territory. The 192.0 GB/s bandwidth is insufficient for 4K workloads, and the 128-bit bus compounds the issue. The card's FP32 performance of 7.127 TFLOPS is respectable for 1080p gaming, but it cannot compensate for the memory limitations at higher resolutions. The data shows that this GPU is best suited for 1080p gaming with settings tuned to Medium or High, and any attempt to run at 1440p or 4K will require significant compromises in visual quality.

How This Combo Ranks

The combination of the Ryzen 5 8400F and RTX 3050 4 GB ranks 1630 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the bottom 9% of all configurations, which is a poor showing for a system that includes a modern Zen 4 CPU. The low rank is almost entirely attributable to the GPU, as the CPU's benchmark scores are solid for its class. The combo's rank suggests that most other tested systems—whether they use older CPUs or different GPU tiers—deliver better frame rates in this specific title.

The ranking becomes more understandable when you consider the GPU's 50th percentile standing. While the RTX 3050 is an average card in general, Microsoft Flight Simulator is a particularly demanding title that punishes low VRAM and limited bandwidth. The 4 GB memory is a severe handicap, and the card's performance in this game is far below what its overall percentile might suggest. In contrast, the CPU's 82nd percentile ranking indicates it is performing well above average, but it cannot overcome the GPU's limitations.

For context, the nearest CPU rivals—the Ryzen 7 2700X, Ryzen AI 5 PRO 340, and Ryzen 5 7500F—all have similar average benchmark scores, with deltas within 0.3%. This means that swapping the CPU for any of these parts would likely produce nearly identical frame rates in this game, as the GPU would remain the bottleneck. The takeaway is that this combo is poorly balanced for Microsoft Flight Simulator, and users would see far better results by pairing the 8400F with a stronger GPU or by dropping to lower resolutions and settings.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the system delivers its best results. Low settings produce 71.8 FPS, which is smooth for a flight simulator. Medium settings yield 56.5 FPS, still playable but with a noticeable dip. High settings drop to 41.7 FPS, and Ultra settings fall to 39.6 FPS. The 1080p numbers show that the card can handle the resolution, but only at Low or Medium settings without significant stutter.

Moving to 2560x1440, the performance drops across the board. Low settings produce 55.2 FPS, a 23% reduction from 1080p. Medium settings yield 46.9 FPS, High settings drop to 32.2 FPS, and Ultra settings fall to 30.8 FPS. At 1440p, only Low settings remain reliably playable, while Medium is borderline and High/Ultra are marginal at best.

At 3840x2160, the card struggles to maintain playable frame rates. Low settings produce 44 FPS, which is technically playable but far from smooth. Medium settings drop to 33.4 FPS, High settings fall to 23.1 FPS, and Ultra settings bottom out at 22.8 FPS. The 4K results are consistently below the 30 FPS threshold for acceptable playability, except for Low settings, which barely exceed it. The data clearly shows that this combo is not suited for 4K gaming in Microsoft Flight Simulator, and even 1440p requires significant compromises.
