Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and the pairing of the AMD Ryzen 5 5600G with the NVIDIA GeForce RTX 5080 produces a fascinating dataset that reveals a clear performance hierarchy across resolutions and settings. The measured results show a system that is heavily GPU-bound at higher resolutions, but which also exposes the CPU's limitations as the graphical load decreases. This analysis breaks down the FPS figures to explain exactly where the bottleneck lies and how to get the best experience from this specific combination.

Resolution Scaling

The FPS data shows a classic scaling pattern, but with a significant twist that highlights the CPU's role. At 1080p with Low settings, the combo achieves 168 FPS. Moving to 1440p Low drops that to 156 FPS, and 4K Low brings it down to 130 FPS. This is a relatively modest 22.6% decrease from 1080p to 4K at Low settings. In contrast, the scaling at Ultra settings is much steeper: 122 FPS at 1080p drops to 98 FPS at 1440p and then plummets to 72 FPS at 4K. That represents a 41% drop from 1080p to 4K on Ultra.

This divergence in scaling behavior tells a clear story. At Low settings, the game is likely becoming CPU-limited even at 1080p, meaning the GPU has spare capacity that isn't being fully utilized. The Ryzen 5 5600G's six cores and 12 threads are working hard to feed the frames, and as resolution increases, the GPU takes on more work, but the CPU is still the primary limiter. The result is that FPS doesn't scale down as aggressively because the CPU is the bottleneck at all resolutions. At Ultra settings, however, the graphical demands are so high that the RTX 5080 becomes the dominant constraint, especially at 4K where the pixel count and effects overwhelm the GPU, leading to the more pronounced FPS drop.

The Medium settings data reinforces this. At 1080p Medium, the average is 153 FPS with a minimum of 130 FPS. At 1440p Medium, it's 137 FPS with a minimum of 116 FPS. At 4K Medium, it's 101 FPS with a minimum of 86 FPS. The gap between the average and minimum FPS also widens at lower resolutions, suggesting that CPU-driven frame time spikes are more noticeable when the GPU is not the limiting factor. This indicates that for smooth gameplay, users should prioritize higher settings at higher resolutions to shift the workload firmly onto the GPU, which is this system's strongest component.

CPU Role

The AMD Ryzen 5 5600G is a 5000-series processor based on the Zen 3 architecture, codenamed Cezanne, and fabricated on a 7 nm process. It features 6 cores and 12 threads, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. Its cache configuration includes 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3. The processor supports dual-channel DDR4 memory and has a TDP of 65 W. In terms of raw compute, its Cinebench R23 multicore score is 10551, and its single-core score is 1409. Its PassMark multithread score is 19717, and its single-thread score is 3177.

Benchmark results indicate that this CPU is a competent mid-range part, but it is clearly not a top-tier performer. Its percentile vs all CPUs is 74, which places it above the majority of processors, but its nearest rivals include the Intel Core i3-1220P (with a deltaPct of 0.1) and the AMD Ryzen 5 7530U (with a deltaPct of -0.2). This places it in a performance bracket that is competitive with mobile and lower-power desktop parts. For a game like Microsoft Flight Simulator, which is known to be sensitive to single-thread performance, the 5600G's single-core capabilities are adequate but not exceptional.

The data suggests that the CPU is a significant factor in the measured results, particularly at 1080p and Low settings. The fact that the FPS at 1080p Low (168 FPS) is not dramatically higher than at 1440p Low (156 FPS) implies that the CPU is reaching its limit. The 3dmark single-thread score of 872 and the 2-thread score of 1705 provide context for its ability to handle the game's main simulation thread. While the 5600G can push high frame rates, it does not have the headroom to fully saturate the RTX 5080 at lower resolutions and settings, leaving performance on the table.

How This Combo Ranks

In the database of tested combinations for Microsoft Flight Simulator, this pairing of the Ryzen 5 5600G and the RTX 5080 holds a combo rank of 301 out of 3714 tested combos. This places it in the top 8.1% of all tested configurations, which is a strong showing overall. This rank is likely driven primarily by the GPU's immense power, as the CPU is a relative weak point in the pairing.

The rank of 301 indicates that while this system is far from the top of the charts, it outperforms the vast majority of other configurations tested in this game. The high rank reflects the RTX 5080's ability to carry the system, especially at higher resolutions and settings where the GPU is the primary bottleneck. However, the CPU's limitations are what prevent this combo from ranking even higher. A system with a more powerful processor would likely see a significantly better rank, particularly in scenarios that are less GPU-intensive.

The data suggests that users with this combo are getting a very good experience, but they are not maximizing the potential of the RTX 5080. The GPU is capable of far more than the CPU can deliver in certain situations, as evidenced by the relatively small FPS gains when lowering settings at 1080p. This ranking serves as a reminder that a balanced system is key, and that this particular pair is somewhat lopsided, with the GPU being the clear performance leader.

Measured FPS Breakdown

The measured FPS data provides a detailed look at performance across three resolutions and four settings presets. At 1920x1080, the results are as follows: Low settings yield an average of 168 FPS, Medium yields 153 FPS with a minimum of 130 and a maximum of 176, High yields 128 FPS, and Ultra yields 122 FPS. The step from Low to Medium is a drop of 15 FPS, while the step from High to Ultra is only 6 FPS, indicating diminishing returns at the highest settings.

Moving to 2560x1440, the averages are 156 FPS for Low, 137 FPS for Medium (with a min of 116 and max of 157), 103 FPS for High, and 98 FPS for Ultra. The drop from Low to Medium is 19 FPS, and from High to Ultra is 5 FPS. At this resolution, the GPU is starting to take on more work, but the CPU is still influencing the results, particularly at Low settings where the FPS is still high.

At 3840x2160, the averages are 130 FPS for Low, 101 FPS for Medium (with a min of 86 and max of 116), 76 FPS for High, and 72 FPS for Ultra. The difference between Low and Medium is 29 FPS, and between High and Ultra is only 4 FPS. At 4K, the GPU is clearly the limiting factor, as the FPS scales much more predictably with the graphical load. The minimum FPS numbers at Medium settings show a pattern: 130 at 1080p, 116 at 1440p, and 86 at 4K, which suggests that frame pacing is more consistent at higher resolutions where the GPU is fully engaged.

GPU Role

The NVIDIA GeForce RTX 5080 is a flagship-level GPU from the GeForce 50-series, based on the Blackwell 2.0 architecture and the GB203 chip, fabricated on a 5 nm process. It boasts 10752 shading units, 336 TMUs, and 112 ROPs. The GPU has 84 RT cores and 336 tensor cores. Its memory configuration includes 16 GB of GDDR7 on a 256-bit bus, providing a bandwidth of 960.0 GB/s. The core clocks are a base of 2295 MHz and a boost of 2617 MHz. The GPU's FP32 performance is 56.28 TFLOPS.

This GPU is an absolute powerhouse, and its benchmark scores reflect that. Its PassMark G3D score is 36565, and its Geekbench Vulkan score is 255450. Its percentile vs all GPUs is 87, which places it in the top 13% of all graphics cards. Its nearest rivals include the AMD Radeon RX 9070 GRE (with a deltaPct of -2.2) and the AMD Radeon 8060S (with a deltaPct of 0.6). This confirms that the RTX 5080 is a top-tier performer that can handle any game at any resolution.

The data indicates that the GPU is the saving grace of this combo. At 4K Ultra, the combo still manages 72 FPS, which is a solid playable frame rate for a flight simulator. The GPU's massive memory bandwidth and compute power are what allow this system to achieve such high frame rates at 4K. The fact that the FPS at 1080p Ultra (122 FPS) is not significantly higher than at 4K Ultra (72 FPS) shows that the GPU is not the bottleneck at 1080p; the CPU is. The GPU is capable of far more, but it is being held back by the processor.

Settings Recommendations

Based on the measured data, the optimal settings for this combo depend heavily on the user's display resolution and preference for visual fidelity versus frame rate. For users with a 4K display, the Ultra preset is the best choice, as it delivers an average of 72 FPS, which is perfectly playable for a simulation game where precise control is more important than ultra-high refresh rates. The High preset at 4K offers 76 FPS, which is a marginal improvement of 4 FPS over Ultra, making Ultra the better choice for the visual quality gain.

For 1440p users, the Ultra preset is again the recommended choice, providing an average of 98 FPS. This offers a smooth experience with high visual quality. The High preset at 1440p yields 103 FPS, which is only 5 FPS higher, so the visual fidelity of Ultra is worth the minor frame rate trade-off. The Medium preset at 1440p (137 FPS) is a viable option for those who prioritize high refresh rates, but the step up to Ultra is more impactful visually.

At 1080p, the situation is more nuanced. The Ultra preset delivers 122 FPS, and the High preset delivers 128 FPS. Both are excellent frame rates for a flight simulator. However, the Low preset at 1080p yields 168 FPS, which is a substantial increase, but the visual quality suffers significantly. The data suggests that the CPU is the limiting factor here, as the FPS gains from lowering settings are relatively small compared to the resolution scaling. For the best experience at 1080p, the Ultra or High preset is recommended, as they provide a good balance of visual quality and performance, and the CPU will not allow for dramatically higher frame rates anyway.
