Microsoft Flight Simulator

The AMD Ryzen 5 2600 paired with the NVIDIA GeForce RTX 4080 presents an interesting study in bottleneck behavior within Microsoft Flight Simulator. The data shows a configuration where a high-end, current-generation graphics card is paired with a previous-generation, mid-range processor. This combination yields playable frame rates across all tested settings and resolutions, but the performance scaling patterns reveal a system that is primarily constrained by the CPU at lower resolutions, with the load shifting toward the GPU as resolution increases.

Resolution Scaling

The measured frames per second (FPS) data shows a clear and consistent pattern of diminishing returns as resolution increases. At 1080p with High settings, the combo produces an average of 97 FPS. Moving to 1440p at the same High preset, the average drops to 90 FPS, a reduction of 7 FPS. The jump to 4K (3840x2160) at High settings results in a further drop to 73 FPS, an additional 17 FPS reduction from the 1440p result.

This scaling curve is telling. The performance gap between 1080p and 1440p is relatively small, suggesting that the CPU is the limiting factor at those resolutions. The frame rate is not scaling up as much as one might expect from a GPU with the raw compute power of the RTX 4080, which indicates that the AMD Ryzen 5 2600 is unable to feed the GPU with enough data to fully utilize its capabilities at lower pixel counts. The larger drop from 1440p to 4K indicates that the GPU is finally becoming the primary bottleneck, as the increased pixel workload begins to saturate its rendering capabilities.

The Low preset results reinforce this interpretation. At 1080p Low, the combo achieves an average of 118 FPS. At 1440p Low, the average is 110 FPS, and at 4K Low, it drops to 99 FPS. The differential between 1080p and 4K at Low settings is 19 FPS, which is a smaller absolute drop than the 24 FPS difference seen at High settings. This suggests that even at Low settings, the CPU is still a significant constraint, as the frame rate does not increase as dramatically as the reduced pixel workload would suggest it should with a fully GPU-bound system.

The Ultra settings present a similar pattern. The difference between 1080p and 1440p Ultra is just 7 FPS (96 vs 89), while the drop from 1440p to 4K Ultra is 19 FPS (89 vs 70). This is consistent with the High settings data and confirms the analysis: the CPU holds back performance at lower resolutions, while the GPU becomes the limiting factor at 4K.

How This Combo Ranks

The combination of the AMD Ryzen 5 2600 and the NVIDIA GeForce RTX 4080 ranks at position 957 out of 3714 tested combos for this game. This places the configuration in the top quarter of all tested systems, which is a respectable position given the age of the processor. The percentile ranking for the CPU alone is 75, indicating that it performs better than three-quarters of all CPUs in the benchmark database. The GPU's percentile ranking is even higher at 86, showing that it outperforms 86 percent of all tested GPUs.

The disparity between the component rankings and the combo ranking is informative. The combo rank of 957 out of 3714 suggests that while the individual components are strong, their pairing is not optimal for this specific title. The data indicates that the Ryzen 5 2600, despite having a decent average benchmark score of 21484, is holding back the RTX 4080 in Microsoft Flight Simulator. The CPU's nearest rivals in terms of average benchmark score include the Intel Core Ultra 5 228V (21440, a 0.2 percent difference) and the Intel Core i9-11900H (21367, a 0.5 percent difference). These rivals have similar average scores, but the data suggests they may not be any better suited for this game's specific demands.

The GPU's nearest rivals include the NVIDIA GeForce RTX 4080 SUPER with an average score of 54209 (a 0.1 percent difference) and the AMD Radeon RX 6750 GRE 12 GB with an average score of 55698 (a -2.6 percent difference). These comparisons show that the RTX 4080 is performing as expected for its class, further emphasizing that the CPU is the component that is limiting the overall system performance in this benchmark.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen architecture, with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. It features a 16 MB shared L3 cache and supports DDR4 memory in a dual-channel configuration. The CPU's benchmark scores, such as a Cinebench R15 multi-core score of 1248 and a single-core score of 157.3, provide context for its performance capabilities. Its Passmark single-thread score is 2239, which is a relevant metric for a game like Microsoft Flight Simulator that often relies on strong single-thread performance for its simulation logic.

The data suggests that this CPU is a limiting factor in this configuration. The FPS results at 1080p, regardless of settings, show a performance ceiling that the RTX 4080 cannot push past. For example, at 1080p Ultra, the system achieves 96 FPS, while at 1440p Ultra, it achieves 89 FPS. This small difference indicates that the CPU is the bottleneck, as the GPU has enough headroom to handle the extra pixels at 1440p without a significant frame rate penalty.

The CPU's 6 cores and 12 threads are adequate for modern gaming, but the Zen architecture's older design, compared to newer offerings, shows its age in this simulation title. The boost clock of 3.90 GHz is modest by today's standards, and the single-thread performance is not exceptional, as evidenced by its ranking relative to other CPUs. The data supports the conclusion that the Ryzen 5 2600 is preventing the RTX 4080 from achieving its full potential in this game, particularly at resolutions below 4K.

FAQ

GPU Role

The NVIDIA GeForce RTX 4080 is a high-end graphics card based on the Ada Lovelace architecture, fabricated on a 5 nm process. It features 16 GB of GDDR6X memory on a 256-bit bus, providing a memory bandwidth of 716.8 GB/s. The GPU has a base clock of 2205 MHz and a boost clock of 2505 MHz. Its compute capabilities are substantial, with an FP32 performance of 48.74 TFLOPS and a texture rate of 761.5 GTexel/s.

The GPU's benchmark results are consistent with its high-end positioning. It achieves a Geekbench Vulkan score of 263779 and a Passmark G3D score of 34457. These scores place it in the 86th percentile of all GPUs, indicating it is more powerful than the vast majority of graphics cards in the database.

In the context of this game, the RTX 4080's role is somewhat diminished by the CPU bottleneck at lower resolutions. The data shows that the GPU is not the limiting factor at 1080p or 1440p, as the frame rates are relatively similar across these resolutions. However, at 4K, the GPU's workload increases significantly, and the performance drop becomes more pronounced, indicating that the RTX 4080 is then the primary bottleneck. The 16 GB of VRAM is ample for this game at 4K Ultra settings, and the high memory bandwidth ensures that texture streaming is not a likely source of stuttering.

The GPU's performance is well within expectations for its class, as its nearest rival, the RTX 4080 SUPER, has an average benchmark score that is only 0.1 percent higher. This indicates that the RTX 4080 is performing as it should, and any performance shortfalls in this benchmark are attributable to the CPU.

Settings Recommendations

For this specific combination of the AMD Ryzen 5 2600 and the NVIDIA GeForce RTX 4080, the data suggests that the Ultra preset provides the best overall experience at 1440p. The measured average FPS at 1440p Ultra is 89, which is a playable frame rate for a flight simulator. The difference between Ultra and High at 1440p is just 1 FPS (89 vs 90), which is negligible. This indicates that the Ultra preset does not impose a significant performance penalty over High, making it the preferred choice for visual quality.

At 4K, the Ultra preset produces an average of 70 FPS. While this is technically playable, it is approaching the lower bounds of what many users consider smooth. The High preset at 4K yields an average of 73 FPS, which is only a 3 FPS improvement. Given the minimal difference, users at 4K might prefer the Ultra settings for the best visual fidelity, as the performance cost is small.

For users who prioritize frame rate above all else, the Low preset at 1080p offers the highest average FPS of 118. However, this comes at a significant cost to visual quality. The Medium preset at 1080p provides an average of 108 FPS and includes the only measured min and max FPS data points (92 min, 124 max), suggesting a stable frame time experience. A reasonable recommendation would be to use the Ultra preset at 1440p for a balanced experience, or the Medium preset at 1080p for a high frame rate with more stable frame pacing.
