Microsoft Flight Simulator

Microsoft Flight Simulator remains one of the most demanding titles in the benchmark suite, and the pairing of the AMD Ryzen 5 8400F with the AMD Radeon RX 6600 produces a clear picture of where the bottlenecks lie. The data shows a system that is heavily constrained by the graphics card at higher resolutions, but which reveals a more balanced profile when settings are lowered. This analysis breaks down the measured frames-per-second (FPS) data across three resolutions and four quality presets, interpreting what the numbers mean for the overall ranking and playability of this specific hardware combination.

Resolution Scaling

The FPS scaling from 1080p to 4K clearly identifies the GPU as the primary limiting component in this configuration. At 1080p with Low settings, the combo achieves an average of 90.5 FPS, which drops to 73.7 FPS at 1440p and further to 53.3 FPS at 4K. This represents a 41% reduction in frame rate from 1080p to 4K at the lowest preset, a substantial hit that points directly at the Radeon RX 6600's rendering capabilities struggling with the increased pixel count.

The pattern becomes even more pronounced at higher quality settings. Moving from 1080p High (56.4 FPS) to 4K High (32.9 FPS) results in a 42% performance loss. The gap between 1080p and 1440p at High settings is 28% (56.4 to 40.4 FPS), while the jump from 1440p to 4K at the same preset is 19% (40.4 to 32.9 FPS). This non-linear scaling suggests that the game's engine is becoming increasingly pixel-bound as resolution rises, with the GPU's 8 GB of memory and 224.0 GB/s bandwidth being saturated by the higher fidelity textures and effects.

Interestingly, the Ultra preset shows the most severe scaling. At 1080p Ultra, the system manages 50.2 FPS, but this falls to 43.1 FPS at 1440p and plummets to 30.4 FPS at 4K. The 39% drop from 1080p to 4K at Ultra is consistent with the other presets, but the absolute numbers reveal that this combo is simply not viable at 4K Ultra, dipping below the 30 FPS threshold that many consider the minimum for playable flight simulation. The data indicates that the CPU, with its 6 cores and 12 threads based on Zen 4 architecture, is not the limiting factor at these resolutions; rather, the RX 6600's 1792 shading units and 64 ROPs are overwhelmed by the pixel workload.

How This Combo Ranks

Within the broader database of tested combinations, this specific pairing of the Ryzen 5 8400F and Radeon RX 6600 holds the 1449th position out of 1795 total combos for Microsoft Flight Simulator. This places it in the lower 20th percentile of all tested systems, indicating that while it is not the weakest configuration, it is significantly outclassed by the majority of hardware pairings in the benchmark results. The rank reflects the combined performance ceiling of both components, and the data suggests that this is a mid-range to entry-level setup for this particularly demanding title.

The CPU itself performs admirably relative to its peers, sitting in the 82nd percentile of all CPUs tested. Its average benchmark score of 25064 is nearly identical to that of the AMD Ryzen 7 2700X, which scores 25057 with a deltaPct of 0, and it is slightly ahead of the AMD Ryzen 5 7500F, which scores 24993 with a deltaPct of 0.3. This indicates that the processor is not the weak link in this system. Conversely, the GPU sits in the 69th percentile of all GPUs, with an average benchmark score of 25235. Its nearest rival, the AMD Radeon RX 580 2048SP, scores 25287 with a deltaPct of -0.2, showing that the RX 6600 is competitive within its class but not exceptional.

The discrepancy between the CPU's high percentile ranking and the GPU's lower percentile, combined with the overall combo rank of 1449, strongly suggests that the graphics card is dragging down the system's performance in this specific game. The data implies that pairing this CPU with a more powerful GPU would yield significantly better results, as the processor has headroom to push more frames if the graphics bottleneck were removed.

Settings Recommendations

For users targeting a smooth experience at 1080p, the data supports using Medium settings, which deliver an average of 72 FPS. This is a substantial improvement over High (56.4 FPS) while still providing a visual quality boost over Low (90.5 FPS). The 28% performance gain from High to Medium is worth the visual compromise, as the frame rate becomes more fluid for the panning views and dense scenery typical of flight simulation. Pushing to Ultra at 1080p yields 50.2 FPS, which is playable but may exhibit stutter during complex flight phases.

At 1440p, the recommended setting is Low, which produces an average of 73.7 FPS. Medium at this resolution drops to 58.3 FPS, which is still acceptable for most users, but the margin for error is slimmer. The data shows that High (40.4 FPS) and Ultra (43.1 FPS) are too demanding for consistent smoothness at 1440p, with frame rates dipping into the mid-30s during intense scenes. For 4K gaming, the only viable option is Low, with an average of 53.3 FPS. Medium at 4K (44.1 FPS) and High (32.9 FPS) are borderline, while Ultra (30.4 FPS) is essentially unplayable for a smooth experience.

The overall recommendation is to prioritize frame rate over visual fidelity with this hardware. The measured data indicates that the sweet spot is 1080p Medium or 1440p Low, as these configurations offer the best balance between smoothness and visual detail without overburdening the GPU. Users with 4K displays should accept Low settings as the baseline for playable performance.

Measured FPS Breakdown

The complete dataset provides a clear matrix of performance across all tested configurations. At 1920x1080, the average frame rates are 90.5 FPS for Low, 72 FPS for Medium, 56.4 FPS for High, and 50.2 FPS for Ultra. This shows a steady decline as visual quality increases, with the gap between Low and Ultra being 44%. At 2560x1440, the averages are 73.7 FPS for Low, 58.3 FPS for Medium, 40.4 FPS for High, and 43.1 FPS for Ultra. Notably, the Ultra preset at 1440p performs slightly better than High, which may indicate a specific optimization or workload distribution in the game engine at this resolution.

At 3840x2160, the results are 53.3 FPS for Low, 44.1 FPS for Medium, 32.9 FPS for High, and 30.4 FPS for Ultra. The 4K results show the most significant drop-off, with the difference between Low and Ultra being 43%. Across all resolutions, the scaling from Low to Ultra is consistent, with an average performance penalty of roughly 40-45% for the highest quality preset. The data also reveals that the jump from Medium to High is generally larger than from Low to Medium, suggesting that the High preset introduces disproportionately heavy effects.

GPU Role

The AMD Radeon RX 6600 plays a critical role in defining this system's performance envelope. Its 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth, which appears to be a significant constraint at higher resolutions and quality settings. The GPU's base clock of 1626 MHz and boost clock of 2491 MHz, with a game clock of 2044 MHz, are relatively modest for modern standards, and the benchmark results reflect this. The 1792 shading units and 64 ROPs are tasked with rendering the complex geometry and textures of Microsoft Flight Simulator, and the data indicates they struggle to keep up at 4K.

The GPU's memory configuration is particularly telling. With only 8 GB of VRAM, the card likely runs into capacity limits when loading high-resolution textures at 4K Ultra, which could explain the severe frame rate drop to 30.4 FPS. The 128-bit memory bus, while efficient for its class, limits the available bandwidth compared to wider-bus competitors. The GPU's performance in the benchmark suite, with a 3DMark Steel Nomad DX12 score of 1492 and a PassMark G3D score of 15096, places it in the 69th percentile, confirming its mid-range positioning.

The GPU's nearest rivals in the benchmark database include the AMD Radeon RX 580 2048SP (deltaPct -0.2) and the NVIDIA GeForce RTX 3060 Ti (deltaPct 0.5), showing that the RX 6600 is closely matched with older and newer mid-range options. However, for this specific game, the data shows that the GPU's architectural limitations, particularly in memory bandwidth and raw compute throughput (8.928 TFLOPS FP32), are the primary barriers to higher frame rates at demanding settings. The CPU, with its strong single-thread performance (Cinebench R23 single-core score of 2943), is clearly not the bottleneck, as evidenced by the significant FPS drops when resolution increases.
