Settings Recommendations

The measured frame rates for Microsoft Flight Simulator with this AMD Ryzen 5 4600G and NVIDIA GeForce RTX 3080 combination reveal a clear pattern across all three tested resolutions: the Medium preset delivers the most balanced experience. At 1080p, Medium produces 122 FPS, which is 34.2% higher than the High preset’s 91.8 FPS while remaining within 15.6 FPS of the Low preset’s 137.6 FPS. The gap between Medium and Ultra at 1080p is substantial — 32.1 FPS — yet the visual uplift from Medium to Ultra is often marginal in a flight simulator where terrain detail and weather effects dominate the scene.

At 1440p, Medium sustains 99.1 FPS, which comfortably exceeds the 60 FPS threshold for smooth panning across dense scenery. High trails at 72.2 FPS, and Ultra drops to 71.5 FPS, nearly identical to High but with a 27.6 FPS deficit versus Medium. The Low preset at 1440p reaches 129.1 FPS, but the visual compromise in a game that relies heavily on cockpit instrumentation readability and horizon clarity makes Low less desirable than Medium.

The 4K results sharpen the recommendation. Medium at 3840x2160 delivers 69.6 FPS, which is playable and smooth for a flight sim where frame pacing matters more than raw speed. High at 4K yields 51.4 FPS, and Ultra drops to 50.1 FPS — both below the ideal smoothness threshold. Low at 4K hits 93 FPS but sacrifices too much detail for a genre that rewards visual fidelity. The data strongly suggests Medium as the default preset across all resolutions, with High serving as a viable option only at 1080p where the 91.8 FPS result remains fluid. For users prioritizing maximum visual quality over frame rate, Ultra at 1080p (89.9 FPS) is the only Ultra setting that stays above 85 FPS.

GPU Role

The NVIDIA GeForce RTX 3080 brings 10 GB of GDDR6X memory across a 320-bit bus, yielding 760.3 GB/s of bandwidth. In Microsoft Flight Simulator, which streams large terrain tiles and high-resolution photogrammetry, this bandwidth headroom is critical. The 4K High result (51.4 FPS) versus 4K Medium (69.6 FPS) shows a 18.2 FPS penalty that stems from increased texture and shading loads rather than pure geometry — the GPU’s 8704 shading units and 272 texture mapping units handle geometry well, but memory pressure at 4K High/Ultra becomes the limiting factor.

The GPU’s boost clock of 1710 MHz (base 1440 MHz) provides consistent throughput, but the data indicates that the RTX 3080 is not the primary bottleneck in this configuration at lower resolutions. At 1080p, the difference between Low (137.6 FPS) and Medium (122 FPS) is only 15.6 FPS, while the jump from Medium to Ultra (89.9 FPS) costs 32.1 FPS. This nonlinear scaling suggests the CPU begins to constrain the GPU as settings rise. The Ryzen 5 4600G, a 6-core/12-thread Zen 2 part with a 4.20 GHz boost clock and 8 MB shared L3 cache, must handle the simulation’s single-threaded physics and AI logic. Its passmark single-thread score of 2653 puts it in the 75th percentile among all CPUs, which is adequate but not exceptional for a sim that heavily favors strong per-core performance.

At 4K, the GPU becomes the clear limiter. The 51.4 FPS High result and 50.1 FPS Ultra result are nearly identical, indicating the GPU is saturated. The RTX 3080’s 29.77 TFLOPS FP32 throughput and 68 RT cores are pushed to their limits at 4K Ultra, but the 10 GB frame buffer may also cause texture thrashing in dense urban areas. The 1440p Ultra result (71.5 FPS) versus 1440p High (72.2 FPS) shows that Ultra offers no meaningful frame rate advantage over High at this resolution — both are GPU-bound, but the settings difference is too small to register. Overall, the RTX 3080 is a strong match for this CPU at 1080p and 1440p, but at 4K it requires Medium settings to maintain playable frame rates.

How This Combo Ranks

This specific combination of AMD Ryzen 5 4600G and NVIDIA GeForce RTX 3080 ranks 587th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the 67th percentile of all configurations. This ranking reflects a pairing where the CPU’s mid-range single-thread performance (75th percentile among all CPUs) is paired with a GPU that sits in the 80th percentile among all GPUs. The 4600G’s passmark single-thread score of 2653, while respectable, creates a ceiling in a sim that rewards high per-core throughput. Meanwhile, the RTX 3080’s passmark G3D score of 25086 provides ample rasterization headroom.

Compared to other combos in the database, this pairing sits comfortably in the upper third, but it does not crack the top tier. The 587th rank out of 1795 suggests that roughly 1200 other configurations deliver higher average frame rates in this specific title. The bottleneck analysis from the measured FPS data supports this ranking: at 1080p Low, the combo hits 137.6 FPS, but the scaling from Low to Ultra (137.6 to 89.9 FPS, a 47.7 FPS drop) indicates that the CPU cannot fully feed the GPU at higher settings. The 4600G’s 3dmark single-thread score of 726 and cinebench r23 single-core score of 1919 are the limiting factors, as flight simulation physics and AI often run on a single primary thread.

The RTX 3080’s nearest rivals in synthetic benchmarks (Radeon Pro Duo, Radeon 880M, RX 7900 GRE, RTX 5070 Ti Mobile) all sit within 1% of its average score, yet the in-game ranking depends heavily on the paired CPU. This combo’s rank reflects a balanced but not exceptional pairing — the GPU is capable of much higher frame rates at lower resolutions, but the CPU’s 6-core/12-thread configuration with 8 MB L3 cache is the constraining factor in this simulation-heavy workload.

Resolution Scaling

The measured FPS data across 1080p, 1440p, and 4K reveals a nonlinear scaling pattern that highlights the shifting bottleneck between CPU and GPU. At Low settings, the frame rate drops from 137.6 FPS at 1080p to 129.1 FPS at 1440p (an 8.5 FPS reduction) and then to 93 FPS at 4K (a 36.1 FPS reduction from 1440p). The modest 6.2% drop from 1080p to 1440p at Low settings indicates that the CPU is the primary limiter at these settings — the GPU has ample headroom to render the lower-complexity scenes, but the CPU’s simulation thread cannot push beyond roughly 137 FPS.

At Medium settings, the scaling steepens: 122 FPS at 1080p, 99.1 FPS at 1440p (an 18.8% drop), and 69.6 FPS at 4K (a 29.8% drop from 1440p). The larger percentage drops as resolution increases show the GPU beginning to assert its influence, but the 1080p Medium result (122 FPS) versus 1080p Low (137.6 FPS) still shows a CPU ceiling — the GPU could render more frames if the CPU could feed it.

High settings exhibit the steepest total scaling: 91.8 FPS at 1080p, 72.2 FPS at 1440p (a 21.4% drop), and 51.4 FPS at 4K (a 28.8% drop from 1440p). The 4K High result is only 1.3 FPS higher than 4K Ultra (50.1 FPS), which demonstrates that the GPU is fully saturated at 4K with high-detail settings. The 1080p High result (91.8 FPS) versus 1080p Medium (122 FPS) shows a 30.2 FPS penalty for the High preset, indicating that the increased shading and texture work at 1080p High still fits within the GPU’s capabilities, but the CPU cannot overcome the simulation overhead.

The scaling from 1080p to 4K at Ultra settings (89.9 to 50.1 FPS, a 44.3% reduction) closely mirrors the High settings scaling (91.8 to 51.4 FPS, a 44% reduction). This convergence at 4K across High and Ultra confirms that the RTX 3080 is the definitive bottleneck at 4K, regardless of whether High or Ultra is selected. Conversely, the 1080p to 1440p scaling at Low settings (only 6.2% drop) confirms that the Ryzen 5 4600G is the limiting component at lower resolutions and settings. The data suggests that 1440p Medium (99.1 FPS) represents the sweet spot where neither component is severely bottlenecked, while 4K Medium (69.6 FPS) is the highest resolution where playable frame rates can be maintained.
