Microsoft Flight Simulator

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9850X3D sits at the heart of this combo, built on the Zen 5 architecture with the Granite Ridge codename. This 8-core, 16-thread processor operates on the AMD Socket AM5 platform and was released for the desktop market. Its base clock is rated at 4.70 GHz, with a boost clock reaching 5.60 GHz, which provides substantial headroom for demanding workloads. The chip draws up to a 120 W TDP, a figure that reflects its positioning as a high-performance desktop part. It is produced on TSMC's 4 nm process node and contains 8,315 million transistors within a 70.6 mm² die. The cache hierarchy is notable: 80 KB of L1 per core, 1 MB of L2 per core, and a substantial 96 MB of shared L3 cache.

For Microsoft Flight Simulator, the CPU's role is primarily in managing the simulation's complex world, physics, and AI traffic calculations. The benchmark results show this processor performing strongly. In Cinebench R23, it scores 22,807 in multi-core and 2,228 in single-core tests. The single-core performance is particularly relevant for flight simulation, as the engine often relies on a few heavily loaded threads for core simulation logic. Its PassMark single-thread score of 4,704 and multithread score of 41,318 indicate a balanced profile that handles both the per-core demands and the overall workload distribution. The data compression score of 474,501 and floating-point math score of 81,998 further suggest quick data throughput, which is relevant for streaming terrain and aircraft systems data during flight.

The processor's percentile ranking places it in the 92nd percentile versus all CPUs, indicating it outperforms the vast majority of tested processors. Its nearest rivals provide context: the Intel Xeon Platinum 8260M scores 58,323 on average benchmark (0.1% behind), the Intel Core i9-14900 scores 58,115 (0.5% behind), while the AMD Ryzen AI 9 HX 470 scores 58,826 (0.7% ahead). The Xeon w5-2545 is essentially tied at 58,504 (0.2% ahead). These are tight margins, showing the 9850X3D is competitively positioned within its performance class. However, for this game specifically, the 96 MB of shared L3 cache is the standout feature — large caches help keep frequently accessed simulation data close to the cores, reducing latency in a game that accesses large datasets repeatedly. The memory support for DDR5 with dual-channel configuration and 89.6 GB/s bandwidth complements this, ensuring the CPU isn't starved for data.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 is the rendering engine here, built on the Ada Lovelace architecture with the AD104 chip, fabricated on TSMC's 5 nm process. It carries 35,800 million transistors on a 294 mm² die, with a transistor density of 121.8 million per mm². The GPU operates with a base clock of 1920 MHz and a boost clock of 2475 MHz. Memory runs at 1313 MHz with 21 Gbps effective speed, paired with 12 GB of GDDR6X across a 192-bit bus, delivering 504.2 GB/s of bandwidth. The GPU has 5,888 shading units, 184 texture mapping units, 64 raster operation units, 46 ray tracing cores, and 184 tensor cores. Its compute capabilities are rated at 29.15 TFLOPS for both FP32 and FP16 (1:1), with pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s.

For Microsoft Flight Simulator, the GPU handles the visual rendering — terrain textures, aircraft models, lighting, and weather effects. The 12 GB of VRAM is a key consideration; flight simulators load extensive texture sets for varied scenery, and this capacity supports High and Ultra settings, though the measured FPS data shows how different presets impact performance. The GPU's benchmark scores are strong: 26,927 in PassMark G3D, 154,858 in Geekbench OpenCL, and 174,152 in Geekbench Vulkan. The DirectX 12 score of 103 and DirectX 11 score of 244 in PassMark reflect its API efficiency. The GPU sits in the 81st percentile versus all GPUs, a solid but not top-tier position.

Its nearest rivals show competitive positioning: the NVIDIA Tesla P4 scores 37,628 on average (0.1% ahead), the AMD Radeon RX Vega 56 scores 37,507 (0.4% ahead), the NVIDIA GeForce RTX 4080 Mobile scores 38,135 (1.3% ahead), and the AMD Radeon PRO W6400 scores 37,157 (1.3% behind). The RTX 4070's average benchmark score of 37,648 places it within a tight cluster, but its feature set — including ray tracing cores and tensor cores — matters for modern game workloads. In this flight sim, the GPU's 200 W TDP and PCIe 4.0 x16 interface ensure it can draw enough power and bandwidth for sustained rendering. The 12 GB VRAM is adequate for the game's texture demands, though the Ultra preset at 4K pushes the highest load, as the FPS data will show.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals clear scaling patterns across resolutions. At 1080p with Low settings, the combo achieves 165 FPS. Moving to 1440p Low, it drops to 133 FPS — a 19.4% reduction. At 4K Low, it falls to 98 FPS — a further 26.3% drop from 1440p, and a 40.6% drop from 1080p overall. This scaling behavior indicates the GPU becomes increasingly the limiting factor as resolution rises, since the CPU workload for simulation logic remains relatively constant while pixel count quadruples from 1080p to 4K.

For Medium settings, the pattern is similar: 128 FPS at 1080p, 103 FPS at 1440p (a 19.5% drop), and 76 FPS at 4K (a 26.2% drop from 1440p, 40.6% from 1080p). The High preset shows 96 FPS at 1080p, 78 FPS at 1440p (18.8% drop), and 57 FPS at 4K (26.9% drop from 1440p, 40.6% from 1080p). Ultra settings follow: 92 FPS at 1080p, 74 FPS at 1440p (19.6% drop), and 55 FPS at 4K (25.7% drop from 1440p, 40.2% from 1080p). The consistency of these percentage drops — all hovering around 19-20% from 1080p to 1440p and 26-27% from 1440p to 4K — points to GPU-bound scaling. The CPU maintains its simulation workload regardless of resolution, so the FPS decline is driven by the GPU's rendering load.

This analysis suggests that at 1080p, the CPU may be more of a limiting factor, as the GPU has headroom to render frames quickly, but the simulation logic caps the framerate. At 1440p and especially 4K, the GPU takes over as the primary bottleneck. The RTX 4070's 12 GB VRAM and 504.2 GB/s bandwidth are sufficient to handle these loads, but the rendering demands of higher resolutions and quality presets reduce FPS proportionally. The data shows no sudden cliffs — just steady, predictable declines — which indicates a balanced system where neither component is drastically underpowered for the other.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired smoothness. At 1920x1080, the Ultra preset delivers 92 FPS, which is playable but not exceptionally high. High settings at 96 FPS offer a marginal improvement, but the Medium preset at 128 FPS provides a substantial boost in smoothness with only a moderate visual quality reduction. For players prioritizing frame rate at 1080p, Medium is the recommended balance, offering 128 FPS without the significant drop to Low's 165 FPS.

At 2560x1440, the recommended preset is High, which averages 78 FPS. This stays above the 60 FPS threshold for smooth gameplay while maintaining visual fidelity. The Ultra preset drops to 74 FPS, which is only 4 FPS lower but may not justify the additional visual load. Medium at 103 FPS is also an excellent choice for those who prefer higher frame rates, sacrificing some visual detail for a 25 FPS advantage over High. Low at 133 FPS is available for competitive or maximum smoothness scenarios, but it degrades the visual experience significantly.

At 3840x2160, the data shows that High settings average 57 FPS, which narrowly exceeds 60 FPS but is close to the edge. Medium settings at 76 FPS provide a more comfortable margin above 60 FPS, making it the recommended choice for 4K play. Ultra at 55 FPS dips below the 60 FPS threshold, which may introduce noticeable stutter in a simulation game. Low at 98 FPS is smooth but sacrifices most visual quality, which undermines the purpose of 4K resolution. For the best 4K experience, Medium settings offer the strongest combination of visual quality and performance, delivering 76 FPS with a minimum of 65 FPS and maximum of 88 FPS.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the Low preset achieves an average of 165 FPS. Medium averages 128 FPS, with a minimum of 109 FPS and maximum of 147 FPS. High averages 96 FPS. Ultra averages 92 FPS. This shows a clear progression: each step up in settings reduces performance, with the largest relative jump between Low and Medium (22.4% decrease) and smaller steps between Medium, High, and Ultra.

At 2560x1440, the Low preset averages 133 FPS. Medium averages 103 FPS, with a minimum of 88 FPS and maximum of 119 FPS. High averages 78 FPS. Ultra averages 74 FPS. The scaling from Low to Medium is a 22.6% decrease, similar to the 1080p pattern. The gap between High and Ultra narrows to just 4 FPS, suggesting diminishing returns at higher settings.

At 3840x2160, the Low preset averages 98 FPS. Medium averages 76 FPS, with a minimum of 65 FPS and maximum of 88 FPS. High averages 57 FPS. Ultra averages 55 FPS. The Medium preset provides the only sub-4K configuration with a minimum above 60 FPS, making it the most reliable for consistent performance at 4K. The High and Ultra presets are nearly identical in performance, differing by only 2 FPS, which suggests the Ultra preset's additional visual effects have minimal performance impact at this resolution.
