Microsoft Flight Simulator

Microsoft Flight Simulator is exceptionally demanding, and the data for the AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 5080 shows a system that can handle the sim, but with clear trade-offs. The measured results indicate that the Medium preset is the sweet spot, offering the best balance of smoothness and visual fidelity across all three tested resolutions. This configuration ranks in the top quarter of tested combos, placing 738th out of 2996, which is a strong showing given the simulator’s notorious performance requirements.

Settings Recommendations

The benchmark data reveals a clear hierarchy in performance across the four settings presets. At 3840x2160 (4K), the Medium preset delivers an average of 75 FPS with a minimum of 64 FPS and a maximum of 86 FPS. This is the only 4K preset that provides a playable frame rate that stays comfortably above the 60 FPS threshold, even in its minimum recorded frame time. In contrast, the High preset drops to an average of 56 FPS, and Ultra falls further to 54 FPS, both of which are below the ideal smoothness target for a flight simulator where camera panning and instrument readability are critical. While Low at 4K achieves 96 FPS, the visual compromise is likely too severe for a game that relies heavily on scenery detail and cockpit readability.

At 2560x1440, the Medium preset again stands out. It produces an average of 102 FPS, with a minimum of 86 FPS and a maximum of 117 FPS. This represents a 26 FPS improvement over High (76 FPS) and a 29 FPS improvement over Ultra (73 FPS) at the same resolution. The 86 FPS minimum is particularly reassuring, as it indicates the system rarely dips below a point where frame pacing becomes noticeable. The Low preset at 1440p hits 131 FPS, but similar to 4K, the reduction in scenery complexity undermines the core experience of the sim.

For 1920x1080, the Medium preset provides an average of 126 FPS, with a minimum of 107 FPS and a maximum of 145 FPS. This is a highly fluid experience, and it is the recommended choice for competitive or high-refresh-rate displays. The High preset at 1080p averages 95 FPS, which is still playable, but the Medium preset’s higher minimum frame rate (107 FPS vs. no recorded minimum for High) suggests better frame-time stability. Ultra at 1080p averages 90 FPS, which is close to High but still below Medium’s performance.

The data strongly suggests that the Medium preset is the optimal configuration. It provides a substantial performance uplift over High and Ultra—typically 35% to 40% higher average FPS—while maintaining the core visual elements that matter for flight simulation, such as terrain detail and object rendering. The Low preset, while faster, sacrifices too much in a game where situational awareness is tied to visual clarity. Therefore, for a consistent and responsive experience, Medium is the clear recommendation across all resolutions.

GPU Role

The NVIDIA GeForce RTX 5080 is the primary driver of the frame rate differences between presets. Its 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is essential for feeding the high-resolution textures and complex geometry that Microsoft Flight Simulator streams in constantly. The GPU’s boost clock of 2617 MHz and base clock of 2295 MHz allow it to sustain high throughput, and the data shows that scaling from Low to Ultra is directly tied to the GPU’s workload.

The performance drop from Medium to High at 4K is 19 FPS (from 75 to 56), and from High to Ultra it is another 2 FPS (to 54). This indicates that the Ultra preset imposes a heavy shading and post-processing load that the RTX 5080 cannot fully offset at 4K. At 1440p, the gap between Medium (102 FPS) and High (76 FPS) is 26 FPS, and at 1080p it is 31 FPS (126 vs. 95). This scaling pattern shows that the GPU is increasingly the limiting factor as resolution rises, but the RTX 5080 still delivers playable results at 4K Medium.

The RTX 5080’s 56.28 TFLOPS of FP32 performance and 112 ROPs are sufficient for the simulator’s rendering workload, but the 4K Ultra result of 54 FPS suggests that the card is near its limits with the most demanding settings. The GPU’s 84 RT cores and 336 Tensor cores do not appear to provide a decisive advantage in this specific benchmark, as the frame rates at Ultra are only marginally better than High at 4K. The 16 GB VRAM capacity is adequate for the data set, as no memory-related stutters are indicated by the min FPS values at Medium settings. Overall, the RTX 5080 is a capable but not overpowering component for this sim; it excels at Medium settings but struggles to maintain high frame rates at Ultra.

How This Combo Ranks

The AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5080 combination ranks 738th out of 2996 tested combos in Microsoft Flight Simulator. This places the system in the 75th percentile of all tested configurations, meaning it outperforms roughly three-quarters of the systems in the database. Given the simulator’s extreme CPU and GPU demands, this is a respectable result.

The ranking suggests that this combo is well-matched for the game’s requirements. The CPU’s high multi-threaded performance, evidenced by its Cinebench R23 multi-core score of 42713, complements the GPU’s strong rasterization capabilities. The 738th rank is not a reflection of a bottleneck but rather the high baseline performance required to run Microsoft Flight Simulator smoothly. Many of the systems ranked above this combo likely feature desktop-class components with higher sustained power limits, whereas this is a mobile CPU (the Ryzen 9 8945HX is a mobile processor with a 55W TDP) paired with a high-end desktop GPU.

Compared to other combos in the database, this pairing shows that the RTX 5080 can push the simulator to playable levels, but the CPU’s mobile nature may limit the absolute maximum FPS. The measured results at 1080p Low (162 FPS) suggest that the CPU can feed the GPU effectively at lower resolutions, but at higher settings, the GPU becomes the primary constraint. The 738th rank is a strong indicator that for a laptop-based CPU, this combination delivers excellent value in raw performance, even if it doesn’t top the charts.

CPU Role

The AMD Ryzen 9 8945HX, with its 16 cores and 32 threads, provides substantial multi-threaded horsepower that is critical for Microsoft Flight Simulator’s complex simulation logic, including flight dynamics, weather systems, and AI traffic. Its base clock of 2.50 GHz and boost clock of 5.40 GHz allow it to handle both single-threaded and multi-threaded workloads effectively. The CPU’s 64 MB of L3 cache is particularly beneficial for the large data sets that the simulator processes, reducing the need for slower memory accesses.

In the measured results, the CPU’s role becomes more apparent at lower resolutions. At 1080p Low, the system achieves 162 FPS, which is significantly higher than at 4K Low (96 FPS). This suggests that at lower resolutions, the CPU is capable of driving the GPU to near its maximum output. The CPU’s Cinebench R23 single-core score of 6030 is strong, but its multi-core score of 42713 is exceptional, indicating that the 16 cores are well-utilized by the simulator’s parallel tasks.

The CPU’s 55W TDP is a constraint for sustained performance in a mobile chassis, but the benchmark results show that it still delivers competitive frame rates. The 8945HX’s nearest rival, the Intel Core Ultra 9 285HX, has an average benchmark score that is only 0.1% higher, showing that the AMD chip is essentially on par with its closest competitor. The CPU’s 95th percentile rank among all CPUs further confirms its high standing. For this game, the CPU is not the bottleneck at Medium settings, as evidenced by the clear FPS scaling between resolutions—the GPU takes over as the limiting factor once the resolution and settings increase.
