Microsoft Flight Simulator

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 4070 delivers a robust Microsoft Flight Simulator experience, with the data indicating that the balanced Medium preset provides the most consistent frame pacing across all tested resolutions. At 1080p, Medium yields 128 FPS average with a tight 109–147 FPS range, while High drops to 96 FPS and Ultra to 92 FPS—the latter two offering diminishing returns for the visual uplift. At 1440p, Medium maintains 103 FPS (88–119 FPS range), still comfortably above the 60 FPS threshold, whereas High falls to 78 FPS and Ultra to 74 FPS. At 4K, Medium remains the only preset that holds above 60 FPS, delivering 76 FPS with a 65–88 FPS range, while High and Ultra dip to 57 and 55 FPS respectively. Given that flight simulators benefit from stable frame times for smooth panning over expansive terrain, the Medium preset is the clear recommendation for this combo, as it preserves playability at 4K and headroom at lower resolutions without sacrificing the fluidity that Low (140 FPS at 1080p, 130 FPS at 1440p, 98 FPS at 4K) sacrifices in visual fidelity.

Settings Recommendations

The measured FPS rows reveal a clear hierarchy where the Medium preset offers the best balance of performance and visual quality for this specific CPU-GPU pairing. At 1080p, Medium achieves 128 FPS average, which is 33% higher than High (96 FPS) and 39% higher than Ultra (92 FPS), yet it retains the visual enhancements that Low (140 FPS) forgoes. The min-max range for Medium at 1080p spans 109–147 FPS, a 38 FPS spread that indicates the CPU is able to feed the GPU consistently without severe hitches. At 1440p, Medium produces 103 FPS average with a 88–119 FPS range, representing a 32% improvement over High (78 FPS) and a 39% improvement over Ultra (74 FPS). The 4K results are decisive: Medium is the only preset exceeding 60 FPS at 76 FPS average, while High (57 FPS) and Ultra (55 FPS) both fall below the threshold that many flight sim enthusiasts consider minimum for smooth scenery rendering. Low at 4K hits 98 FPS, but the visual compromise is substantial for a game where cockpit readability and terrain detail are central. Therefore, the data supports Medium as the optimal setting, particularly because it preserves a playable frame rate at 4K while still allowing higher refresh rate monitors to be utilized at 1440p.

GPU Role

The NVIDIA GeForce RTX 4070 carries the primary rendering load in Microsoft Flight Simulator, and its 12 GB of GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth proves sufficient for the tested presets. The GPU’s boost clock of 2475 MHz, up from a 1920 MHz base, allows it to maintain high throughput across scenes with dense photogrammetry and dynamic weather. The 5888 shading units, 184 texture mapping units, and 64 ROPs, combined with 46 RT cores and 184 tensor cores, provide the computational foundation for the game’s DirectX 12 rendering path. The FP32 throughput of 29.15 TFLOPS is a strong indicator of raw rasterization capability, which the benchmark results reflect in the scaling from Low to Ultra. At 1080p Low, the GPU achieves 140 FPS, but at 4K Ultra it drops to 55 FPS—a 61% reduction that demonstrates the GPU’s sensitivity to pixel count and the game’s heavy reliance on shader complexity at higher quality settings. The 12 GB VRAM capacity is not a limiting factor in these measurements, as even the 4K Ultra preset (55 FPS) does not show evidence of memory swapping; instead, the performance curve aligns with the GPU’s compute and bandwidth limits. Notably, the RTX 4070’s percentile rank of 81 among all GPUs in the database, with an average benchmark score of 37648, places it in the upper tier, and its nearest rivals—such as the NVIDIA Tesla P4 (0.1% delta) and AMD Radeon RX Vega 56 (0.4% delta)—underscore its position as a high-end part that can handle flight simulation at demanding resolutions.

Resolution Scaling

The measured FPS data shows a predictable degradation as resolution increases, but the magnitude varies by preset, revealing where the bottleneck shifts. For Medium settings, the average FPS drops from 128 at 1080p to 103 at 1440p (a 20% reduction) and then to 76 at 4K (a further 26% reduction from 1440p). This scaling suggests that at 1080p, the CPU has more influence on the result, while at 4K, the GPU becomes the dominant constraint. For High settings, the progression is 96 FPS at 1080p, 78 FPS at 1440p (a 19% drop), and 57 FPS at 4K (a 27% drop from 1440p). Ultra follows a similar pattern: 92 FPS at 1080p, 74 FPS at 1440p (a 20% drop), and 55 FPS at 4K (a 26% drop). Low settings show the steepest absolute decline, from 140 FPS at 1080p to 130 FPS at 1440p (a 7% drop) and then to 98 FPS at 4K (a 25% drop from 1440p). The relatively small 1080p-to-1440p delta for Low (7%) indicates that the CPU is likely the limiting factor at lower resolutions and settings, as the GPU has ample headroom. Conversely, the larger 1440p-to-4K deltas across all presets (25–27%) confirm that the GPU’s fill rate and bandwidth are taxed more heavily at higher pixel counts. This pattern is typical of a paired component set where the RTX 4070 is the stronger partner, and it explains why Medium at 4K (76 FPS) still outperforms High at 4K (57 FPS) by 33%, as the reduced shader complexity allows the GPU to maintain higher utilization without being bottlenecked by the CPU’s Zen 2 architecture.

How This Combo Ranks

In the database of tested CPU-GPU combinations for Microsoft Flight Simulator, this pairing of the Ryzen 5 4600G and RTX 4070 achieves a combo rank of 1015 out of 3714 tested combos, placing it in the 73rd percentile of all configurations. This rank is notable because it places the combo in the upper quarter of tested systems, despite the CPU being a relatively modest 6-core, 12-thread part. The ranking reflects the GPU’s dominance in determining overall performance, as the RTX 4070’s 81st percentile among GPUs (with an average benchmark score of 37648) pulls the combo upward, while the CPU’s 71st percentile (with an average benchmark score of 17507) does not significantly drag it down. The gap between the CPU and GPU percentiles—10 percentage points—indicates that the system is not perfectly balanced, but for flight simulation, which is known to be GPU-intensive at higher settings, this imbalance is acceptable. The combo’s position at rank 1015 suggests that there are 1014 other tested combinations that deliver higher average FPS in this game, but many of those likely feature more powerful CPUs; the data shows that the RTX 4070 is capable of extracting playable performance even when paired with a lower-tier processor, as evidenced by the 4K Medium result of 76 FPS. This rank also implies that users with this combo should not expect top-tier performance in CPU-bound scenarios, but the measured FPS at all resolutions and settings demonstrates that the experience remains fluid for most use cases.

CPU Role

The AMD Ryzen 5 4600G, built on the Zen 2 architecture with a 7 nm process, provides 6 cores and 12 threads with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its 8 MB shared L3 cache and 51.2 GB/s memory bandwidth are modest by modern standards, and the CPU’s benchmark scores—such as 13593 in Cinebench R23 multicore and 1919 in single-core—place it at the 71st percentile among all CPUs. In Microsoft Flight Simulator, the CPU’s role is most apparent at lower resolutions and settings, where the GPU is not saturated. At 1080p Low, the combo achieves 140 FPS, but this is only 9% higher than the 4K Low result of 98 FPS, suggesting that the CPU can deliver frames up to a certain point but the GPU still has headroom. More tellingly, the single-thread performance (1919 in Cinebench R23) is critical for flight simulation’s main thread, which handles game logic and terrain loading; the Ryzen 5 4600G’s single-core score is sufficient to avoid severe bottlenecks, as evidenced by the 1080p Medium result of 128 FPS with a 109 FPS minimum. The CPU’s 12 threads also help with background simulation tasks, and the 3DMark 16-thread score of 4863 indicates that multi-threaded workloads are handled competently. However, when compared to its nearest rivals—the AMD Ryzen 3 PRO 5355GE (0.1% delta), Intel Core 7 150U (0.6% delta), and Intel Core i3-14100T (-0.8% delta)—the 4600G sits in a tight performance band, showing that it is neither a standout nor a liability in this context. The data suggests that the CPU is adequate for the GPU’s capabilities, and the primary bottleneck at higher resolutions is clearly the GPU, as the FPS drops from 1080p to 4K are consistent with GPU-bound behavior.

The data shows a consistent pattern: Medium provides the most balanced experience, with FPS ranges that indicate stable frame delivery. At 1080p, the spread between Medium and Ultra is 36 FPS (128 versus 92), while at 1440p the spread narrows to 29 FPS (103 versus 74), and at 4K it tightens further to 21 FPS (76 versus 55). This compression at higher resolutions confirms that the GPU becomes the limiting factor, as the CPU’s ability to feed frames is less relevant when pixel throughput dominates. Low settings always yield the highest FPS, but the visual trade-off is significant for a sim that relies on detailed terrain and cockpit instrumentation. The 4K Low result of 98 FPS is particularly noteworthy, as it demonstrates that the GPU is capable of high frame rates even at 4K when the rendering load is reduced, but the Medium preset at 76 FPS represents the better compromise for visual quality and performance. The min FPS values for Medium at all resolutions—65 at 4K, 88 at 1440p, and 109 at 1080p—show that the combo avoids severe frame drops, which is critical for maintaining smooth panning over dense scenery. There are no min or max FPS values recorded for High, Low, or Ultra presets, so the analysis relies on the average FPS for those settings, but the available range data for Medium provides additional confidence in its consistency.
