Microsoft Flight Simulator

Microsoft Flight Simulator places unusual demands on a system, and the measured data for the AMD Ryzen 5 7600 paired with the NVIDIA GeForce RTX 5080 reveals a configuration that shifts its bottleneck character dramatically depending on resolution and preset. The benchmark rows show a clear progression: at 1080p Low the combo produces 204.8 FPS average, which is a figure that indicates the CPU is doing the heavy lifting, while at 4K Ultra the average drops to 71.4 FPS, where the GPU becomes the limiting factor. This analysis walks through the resolution scaling, the specific roles of the GPU and CPU, and what settings deliver the best experience based strictly on the measured rows.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but not uniform across presets, which tells a story about where the workload shifts. At Low settings, the average frame rate falls from 204.8 FPS at 1920x1080 to 177.6 FPS at 2560x1440, then to 130.9 FPS at 3840x2160. That is a 36% reduction from 1080p to 4K at Low, but the absolute numbers remain high enough to suggest the CPU is still feeding frames efficiently even at the highest resolution. At Ultra settings, the drop is more severe: 126.4 FPS at 1080p, 98.8 FPS at 1440p, and 71.4 FPS at 4K—a 43% decline from 1080p to 4K. The gap between Low and Ultra at 1080p is 78.4 FPS, but at 4K that same gap narrows to 59.5 FPS, indicating that as resolution climbs, the GPU’s rendering workload dominates and the CPU headroom becomes less relevant.

The intermediate presets show a predictable pattern. Medium at 1080p averages 175.3 FPS, falling to 138.9 FPS at 1440p and 100.7 FPS at 4K. High settings produce 131 FPS at 1080p, 102.8 FPS at 1440p, and 74.3 FPS at 4K. The scaling efficiency—how much FPS is lost per pixel increase—is nearly linear for Medium and High, but Ultra shows a slight nonlinearity at the top end, with the 4K figure dropping below what a pure pixel-count scaling would predict. This suggests that at Ultra, certain effects or draw distances are disproportionately taxing the GPU’s compute units, not just its memory bandwidth. For a flight simulator, where the view often includes vast terrain and complex geometry, the data points to the RTX 5080 being the primary constraint at 4K, while at 1080p the Ryzen 5 7600’s six cores are able to keep up with the lower rendering load, producing frame rates above 200 FPS only at Low.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing, and its specifications explain the 4K behavior. It carries 16 GB of GDDR7 memory on a 256-bit bus, yielding a bandwidth of 960.0 GB/s, which is ample for the high-resolution textures Flight Simulator pushes. The base clock is 2295 MHz with a boost of 2617 MHz, and the memory runs at 1875 MHz with 30 Gbps effective speed. In terms of raw throughput, the GPU delivers 56.28 TFLOPS of FP32 performance, which is a figure that aligns with the 4K Ultra result of 71.4 FPS being playable but not silky. The GPU’s percentile ranking versus all GPUs is 89, meaning it outperforms the vast majority of cards in the database, but the nearest rival data shows a tight cluster: the Intel Arc A570M scores 58239 with a delta of 1.6%, and the AMD Radeon Pro W5500X scores 57661 with a delta of 2.6%. The RTX 5080’s average benchmark score is 59188, which is only 1.9% ahead of the Arc Pro A60, indicating that in synthetic tests, the card is not an outlier but rather a solid upper-midrange performer.

In this game specifically, the GPU’s role becomes evident when comparing the Low preset at 4K (130.9 FPS) to the Ultra preset at 4K (71.4 FPS). That 59.5 FPS gap is almost entirely due to the GPU’s shading units (10752), texture mapping units (336), and ray tracing cores (84) being pushed harder by Ultra settings. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are high, but Flight Simulator’s draw calls for terrain and weather effects can saturate even these resources. The fact that the GPU’s passmark G3D score is 36565, with a compute score of 21789, suggests that the card’s rasterization strength is its primary asset, but the compute-heavy aspects of flight simulation—such as physics for weather—may not scale perfectly with those raw numbers. The 16 GB VRAM is not a limiting factor in the measured rows, as no settings combination shows a precipitous drop that would indicate memory swapping, but the bandwidth is likely why 4K Medium (100.7 FPS) holds up better than 4K Ultra.

CPU Role

The AMD Ryzen 5 7600 is a six-core, 12-thread processor from the 7000 series, built on TSMC’s 5 nm process with a base clock of 3.80 GHz and boost clock of 5.10 GHz. Its 32 MB of shared L3 cache and 83.2 GB/s memory bandwidth are modest by modern standards, but the single-thread performance is strong: the 3dmark single-thread score is 999, and the Cinebench R23 single-core score is 3246. These numbers are relevant because Flight Simulator is known to be sensitive to single-core performance for game logic and draw call submission. The CPU’s percentile versus all CPUs is 83, and its nearest rival is the AMD Ryzen 7 5800X3D, which has an average score of 26574 and a delta of just 0.2%—the 7600 edges it out slightly with a 26617 average. This tight grouping means the 7600 is a capable mid-pack CPU, but not a top-tier one.

In the measured FPS, the CPU’s influence is most visible at 1080p Low, where the combo hits 204.8 FPS. That figure is likely near the CPU’s maximum frame rate ceiling for this game, as the GPU is barely stressed at that low resolution and preset. At 1080p Ultra, the FPS drops to 126.4, which is still high but shows that even at the same resolution, the CPU must handle more draw calls for shadows and reflections, reducing its headroom. The 3dmark multi-thread scores—6499 for 16 threads and 6503 for max threads—indicate that the CPU scales well with additional threads, but the fact that the 1080p Low result (204.8) is only 16% higher than the 1440p Low result (177.6) suggests that the CPU is not the primary bottleneck at higher resolutions. The boost clock of 5.10 GHz is the key feature here, as it allows the CPU to maintain high single-core throughput, which the data shows is sufficient to avoid severe frame drops at 4K, where the GPU is clearly the limiting component.

Settings Recommendations

Based on the measured rows, the optimal balance between visual quality and frame rate is the Medium preset. At 1920x1080, Medium yields 175.3 FPS, which is only 29.5 FPS below Low but provides a substantial upgrade in scenery detail. At 2560x1440, Medium averages 138.9 FPS, which is highly playable for a flight simulator where smoothness matters for instrument reading. Even at 3840x2160, Medium holds 100.7 FPS, which is above the 60 FPS threshold for comfortable gameplay and only 30.2 FPS below Low. The Ultra preset offers diminishing returns: at 1080p it produces 126.4 FPS, which is 48.9 FPS lower than Medium, and at 4K it drops to 71.4 FPS, which is 29.3 FPS lower than Medium. The High preset sits between Medium and Ultra, but its 4K result of 74.3 FPS is barely better than Ultra’s 71.4 FPS, making High a poor choice at that resolution.

For users with a 1080p or 1440p monitor, Medium is the clear winner: it delivers frame rates above 138 FPS at both resolutions, which is more than sufficient for a simulation where frame pacing is more important than raw FPS. At 4K, Medium’s 100.7 FPS is the sweet spot, as it maintains fluid motion while allowing the RTX 5080 to render more detailed terrain. Low settings are only recommended if the user prioritizes maximum FPS, but the data shows that the jump from Low to Medium costs only 29.5 FPS at 1080p, 38.7 FPS at 1440p, and 30.2 FPS at 4K—a reasonable trade for the visual fidelity gain. Ultra should be avoided at 4K unless the user is willing to accept frame rates below 75, and even at 1080p, the 126.4 FPS average does not justify the visual improvement over Medium.

How This Combo Ranks

The combination of the Ryzen 5 7600 and RTX 5080 ranks 70th out of 1795 tested combos for Microsoft Flight Simulator, placing it in the top 4% of all configurations in the database. This ranking is influenced by the GPU’s strong 4K performance and the CPU’s ability to sustain high frame rates at lower resolutions. The combo’s rank is notable because the CPU is only in the 83rd percentile versus all CPUs, while the GPU is in the 89th percentile, meaning the pairing is slightly mismatched—the GPU is relatively stronger than the CPU. However, the measured data shows that this mismatch does not cause a severe bottleneck at any resolution, as the lowest FPS figure (71.4 at 4K Ultra) is still playable. The nearest rival CPUs, such as the Intel Core i9-12900HK (delta -0.2%) and the AMD EPYC 8024P (delta 0.2%), show that the 7600 is competitive with higher-tier chips in synthetic benchmarks, which translates to consistent frame delivery in this game.

The rank of 70 out of 1795 implies that there are 69 combos that perform better, but the data does not specify which those are. Given that the RTX 5080’s nearest GPU rivals (Intel Arc A570M, Arc Pro A60) have lower average scores, it is likely that better-performing combos pair the RTX 5080 with a stronger CPU, such as a higher-core-count Ryzen 9 or a Core i9. However, the deltaPct values for the CPU rivals are all under 0.3%, which suggests that upgrading the CPU would not yield a dramatic improvement in Flight Simulator’s frame rates, as the game appears to be GPU-bound at higher settings. The combo’s rank is thus proof of the RTX 5080’s capability, and the CPU’s role is to avoid holding the GPU back, which it does successfully.
