Microsoft Flight Simulator

Resolution Scaling

The measured frame rates for Microsoft Flight Simulator across three resolutions reveal a system that remains impressively fluid even at the highest pixel counts, though the scaling pattern indicates a shift in bottleneck behavior as resolution increases.

At 1080p with Low settings, the combination of the AMD Ryzen 5 7600X and NVIDIA GeForce RTX 5080 produces 217 FPS. This is the highest figure recorded in the entire dataset, and it strongly suggests that at this resolution and preset, the CPU is the primary limiting factor. The 7600X, with its 6 cores and 12 threads, posts a single-thread Geekbench score of 2892 and a Cinebench R23 single-core result of 3406, which are the figures most relevant to a flight simulator's main thread. The frame rate ceiling at 1080p Low is a direct reflection of this processor's single-core capability.

Stepping up to 1440p Low, the average FPS drops to 175.4. This represents a 19.2% reduction from the 1080p result. The delta between 1080p and 1440p is notable, but the more significant information comes from the 4K Low figure of 129.8 FPS. The transition from 1440p to 4K Low costs another 26% of performance. The pattern across the Low preset—from 217 to 175.4 to 129.8—shows a steady decline, but the system remains far above playable thresholds even at 4K.

The scaling behavior changes character when examining the High and Ultra presets. At High settings, the 1080p result is 133 FPS, which drops to 102.7 at 1440p and then to 78.5 at 4K. The percentage drops here are shallower between 1080p and 1440p (22.8% reduction) than they are between 1440p and 4K (23.6% reduction). The Ultra preset tells a similar story: 124.4 FPS at 1080p, 102.1 at 1440p, and 69.5 at 4K.

The key insight is that the Low preset results show the largest absolute FPS range (87.2 FPS between 1080p and 4K), while the Ultra preset shows a narrower range (54.9 FPS). This is counterintuitive at first glance. Heavier presets typically amplify resolution scaling because they increase pixel-level work. However, the data suggests that at Ultra settings, the GPU is already heavily loaded even at 1080p, which compresses the relative differences between resolutions. The RTX 5080, with its 16 GB of GDDR7 memory on a 256-bit bus delivering 960.0 GB/s of bandwidth, has the resources to handle the increased pixel count, but the frame rate still falls as expected due to raw shading throughput limits.

The 4K Ultra result of 69.5 FPS is the lowest figure in the dataset, yet it remains comfortably within the range of smooth gameplay for a flight simulator. The scaling from 1440p Ultra (102.1 FPS) to 4K Ultra (69.5 FPS) represents a 31.9% drop, which is the steepest percentage penalty observed across all presets. This indicates that at the highest quality settings, the GPU becomes the definitive limiting component at 4K, a conclusion reinforced by the fact that the RTX 5080's benchmark scores place it in the 89th percentile of all GPUs, with an average benchmark score of 59188.

Settings Recommendations

The measured data provides a clear hierarchy of performance across the four presets, and the choice of optimal settings depends heavily on the target resolution and the user's preference for visual fidelity versus headroom.

For 4K displays, the Medium preset delivers 100.8 FPS, which is a substantial 31.4% improvement over the Ultra preset's 69.5 FPS. The jump from Medium to High at 4K costs 22.3 FPS (from 100.8 down to 78.5), while the jump from High to Ultra costs only 9 FPS (from 78.5 down to 69.5). This non-linear scaling suggests that the Ultra preset at 4K is paying a significant cost for marginal visual gains, and the Medium preset represents the sweet spot for maintaining high frame rates without sacrificing too much visual detail. The 4K Medium result of 100.8 FPS is nearly double the 4K Ultra result, making it the clear recommendation for users who prioritize smoothness over absolute image quality.

At 1440p, the situation is more forgiving. The High preset produces 102.7 FPS, which is functionally identical to the 4K Medium result. The Ultra preset at 1440p achieves 102.1 FPS, meaning there is only a 0.6% difference between High and Ultra at this resolution. The data shows that the 1440p Ultra and 1440p High results are within 0.6 FPS of each other, which is within measurement noise. Given this, there is little reason to choose High over Ultra at 1440p when the performance cost is essentially zero. The Medium preset at 1440p offers 140.8 FPS, which is a 37.9% improvement over Ultra, but the visual downgrade from Ultra to Medium is more perceptible at this resolution than the performance gain is necessary.

For 1080p users, the story is about headroom. The Ultra preset runs at 124.4 FPS, which is already well above the threshold where most displays can show a difference. The Low preset at 217 FPS is only useful for competitive scenarios or for users with extremely high refresh rate monitors, but the visual compromise is severe. The Medium preset at 172.8 FPS offers a better balance, but the Ultra preset at 124.4 FPS is the recommended choice for 1080p because it provides the highest visual quality while still maintaining frame rates that exceed the refresh rate of typical 1080p monitors. The data indicates that at 1080p, the CPU's single-thread performance becomes the bottleneck at lower presets, so users are not actually gaining meaningful frame rate headroom by dropping from Ultra to Medium—the gains from 124.4 to 172.8 FPS are real but come at a steep visual cost.

The overall recommendation across the dataset is that Medium at 4K, Ultra at 1440p, and Ultra at 1080p provide the best balance of measured performance and visual quality. The combo rank of 57 out of 1795 measured combinations places this system in the top 3.2% of tested configurations, which supports the conclusion that this hardware pairing can handle aggressive settings at any resolution.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing, and its specifications directly explain the frame rate behavior observed in the measured data. The GPU features 10752 shading units, 336 texture mapping units, and 112 raster output units, with a boost clock of 2617 MHz. These figures translate to a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s, which are the raw throughput metrics that govern how quickly the GPU can fill pixels and apply textures at increasing resolutions.

The 16 GB of GDDR7 memory is a critical resource for Microsoft Flight Simulator, a game known for streaming large amounts of terrain and scenery data. The memory operates at 1875 MHz with a 30 Gbps effective data rate across a 256-bit bus, yielding a memory bandwidth of 960.0 GB/s. This bandwidth figure is directly relevant to the 4K results, where the GPU must access textures and geometry data at much higher rates than at 1080p. The fact that the 4K Ultra preset still manages 69.5 FPS suggests that the memory subsystem is not a limiting factor—the GPU's compute throughput is the constraint.

The RTX 5080's benchmark results place it firmly in the high-end segment. Its Passmark G3D score of 36565 and 3DMark Steel Nomad DX12 score of 8637 are strong indicators of its rasterization performance. The GPU's average benchmark score of 59188 puts it in the 89th percentile of all GPUs, and its nearest rivals include the Intel Arc A580 (with a deltaPct of 2.5) and the AMD Radeon Pro W5500X (with a deltaPct of 2.6), meaning the RTX 5080 outperforms these by roughly 2.5% in aggregate benchmarks. The GPU's 84 RT cores and 336 tensor cores are present for ray tracing and DLSS workloads, though the measured FPS data does not include ray tracing or upscaling results.

The GPU's architecture is Blackwell 2.0 on a 5 nm process from TSMC, with 45,600 million transistors on a 378 mm² die. The FP32 compute performance of 56.28 TFLOPS is the headline number for raw shader throughput, and it explains why the GPU can maintain 129.8 FPS at 4K Low settings. The GPU's power envelope is rated at 360 W TDP with a suggested PSU of 750 W, which indicates the thermal and power headroom required to sustain these clock speeds under load.

CPU Role

The AMD Ryzen 5 7600X is a 6-core, 12-thread processor based on the Zen 4 architecture (codenamed Raphael), built on a 5 nm process from TSMC. Its base clock of 4.70 GHz and boost clock of 5.30 GHz are the specifications that most directly influence Microsoft Flight Simulator's performance, given the game's well-documented reliance on single-threaded CPU performance for its simulation and rendering logic.

The measured FPS data reveals the CPU's influence most clearly at lower resolutions and settings. At 1080p Low, the system produces 217 FPS, which is the highest result in the dataset. This figure is unlikely to be limited by the RTX 5080, which has ample headroom at this resolution and preset. Instead, the 7600X's single-thread performance is the ceiling. The processor's Cinebench R23 single-core score of 3406 and Geekbench single-core score of 2892 are the relevant metrics, and they place the 7600X in the 83rd percentile of all CPUs with an average benchmark score of 26272. Its nearest rival, the AMD Ryzen 7 PRO 6850U, has a deltaPct of 0, meaning the two processors are statistically tied in aggregate performance.

The CPU's multithreaded capabilities are also relevant, though to a lesser degree. The 7600X scores 24128 in Cinebench R23 multicore and 12905 in Geekbench multicore. These figures reflect the processor's ability to handle the auxiliary threads that Microsoft Flight Simulator spawns for terrain loading, AI traffic, and weather simulation. The 32 MB of shared L3 cache is a substantial pool that helps maintain data locality for these workloads, and the dual-channel DDR5 memory support with 83.2 GB/s of bandwidth ensures that the CPU can feed data to the GPU without becoming a bottleneck at higher resolutions.

The scaling data supports the conclusion that the CPU is the limiting factor at 1080p Low. The jump from 1080p Low to 1440p Low costs 41.6 FPS (from 217 to 175.4), which is a significant drop that suggests the GPU is starting to take over as the bottleneck. At 4K Low, the result is 129.8 FPS, which is still high but represents a much larger drop from 1440p. The pattern across the Low preset shows the transition from CPU-limited to GPU-limited behavior as resolution increases.

The 7600X's launch MSRP is $299, and it was released in September 2022. Its 105 W TDP and unlocked multiplier make it a flexible platform for overclocking, though the measured data does not include overclocked results. The processor's 3DMark scores show a scaling pattern from 2028 in the 2-thread test to 6879 in the 16-thread test, with the 8-thread score of 5715 representing the sweet spot for the game's thread utilization. The Passmark multithread score of 28390 and single-thread score of 4135 provide additional context for the CPU's overall capability.

In the context of Microsoft Flight Simulator, the 7600X's single-thread performance is sufficient to drive the RTX 5080 to high frame rates at 1080p and 1440p, but the data shows diminishing returns at higher resolutions where the GPU becomes the constraint. The fact that the 4K Ultra result of 69.5 FPS is the lowest in the dataset indicates that the CPU is not the limiting factor at this resolution; the GPU's pixel throughput is. Conversely, the 1080p Low result of 217 FPS demonstrates that the CPU can push the system well beyond typical display refresh rates when the GPU load is minimal.
