Microsoft Flight Simulator

# Microsoft Flight Simulator — AMD Ryzen 9 5950X + NVIDIA GeForce RTX 4070

This combination of AMD's 16-core Ryzen 9 5950X and NVIDIA's RTX 4070 delivers a solid flight-simulation experience, with measured frame rates ranging from 55 FPS at 4K Ultra to 165 FPS at 1080p Low. The data shows a system that scales predictably across resolutions and settings, though the GPU becomes the primary constraint at higher resolutions while the CPU's substantial thread count keeps minimums healthy. Benchmark results indicate this pairing ranks 833rd out of 3,714 tested combos, placing it in the top quarter of all configurations for this title.

Resolution Scaling

Across the three tested resolutions, Microsoft Flight Simulator exhibits a clear and expected dependency on pixel count. At 1920x1080 with Low settings, the system achieves 165 FPS average; stepping up to 2560x1440 Low drops that to 133 FPS, and at 3840x2160 Low it falls to 98 FPS. That represents a 20% reduction from 1080p to 1440p, followed by another 26% reduction from 1440p to 4K at Low settings. The scaling pattern suggests that even at the lowest settings, the GPU is beginning to feel the load as resolution climbs.

The High preset tells a similar story. At 1080p High the average is 96 FPS, which falls to 78 FPS at 1440p High (a 19% drop) and then to 57 FPS at 4K High (a 27% drop from 1440p). The consistent percentage losses across Low and High presets indicate that resolution scaling is largely independent of the graphics workload — the RTX 4070's 12 GB frame buffer and 504.2 GB/s bandwidth are being taxed proportionally as pixel counts rise.

Ultra settings amplify this trend. Starting at 92 FPS on 1080p Ultra, the frame rate drops to 74 FPS at 1440p Ultra and 55 FPS at 4K Ultra. The gap between 1080p and 4K Ultra is 37 FPS, or roughly 40% — a larger absolute loss than the Low preset's 67 FPS gap, but proportionally similar. This indicates that the limiting component shifts from the CPU at low resolutions and settings to the GPU as both resolution and graphical complexity increase.

The min FPS data, available only for Medium settings, reinforces this interpretation. At 1080p Medium, the minimum is 109 FPS; at 1440p Medium it is 88 FPS; at 4K Medium it drops to 65 FPS. These minimums track closely with the averages, suggesting no severe frame-time spikes or CPU bottlenecks that would cause erratic behavior. The system maintains consistent performance even when pushed to 4K, though the 65 FPS minimum at 4K Medium indicates that the GPU is nearing its comfortable operating envelope.

CPU Role

The AMD Ryzen 9 5950X provides 16 cores and 32 threads based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. In synthetic benchmarks, this processor scores 26,017 in Cinebench R23 multi-core and 1,614 in single-core, with a 3DMark 16-thread score of 10,810. The CPU's percentile ranking of 91 among all processors places it well above average, and its nearest rivals include the Intel Core Ultra 5 235HX (with a delta of -0.2%), the AMD EPYC 8124P (-0.3%), and the Intel Core i9-13900F (+0.4%). These deltas are all within 1%, indicating that the 5950X sits in a tightly contested performance band.

For Microsoft Flight Simulator, the CPU's role is most evident at lower resolutions where the GPU is less stressed. At 1080p Low, the system produces 165 FPS, which is the highest measured result across all configurations. This suggests that the CPU has sufficient headroom to feed the GPU at this resolution, and the frame rate is likely GPU-limited even at Low settings. The 5950X's high single-thread performance (1,614 in Cinebench R23 single-core) is particularly relevant, as flight simulators typically rely heavily on a few main threads for game logic and physics.

At 4K Ultra, the average drops to 55 FPS, but the CPU is unlikely to be the constraint at that point — the RTX 4070's 29.15 TFLOPS of FP32 compute is being fully utilized by the demanding Ultra preset. The data shows that going from 1080p Ultra (92 FPS) to 4K Ultra (55 FPS) represents a 40% reduction, while the CPU's core count and clock speeds remain unchanged. This indicates that the CPU is not the limiting factor at high resolutions; instead, the GPU's pixel throughput and memory bandwidth dictate the ceiling.

The 5950X's 64 MB of L3 cache and 51.2 GB/s memory bandwidth provide ample data delivery for the game's streaming-heavy terrain and aircraft models. The processor's 3DMark multi-thread scores (11,597 at max threads) suggest that even if the game were to scale across all cores, the CPU would have substantial reserve capacity. However, the measured FPS data does not show a scenario where CPU performance becomes the bottleneck — even the lowest average of 55 FPS is well above what would indicate a CPU stall.

GPU Role

The NVIDIA GeForce RTX 4070, built on the Ada Lovelace architecture with a 5 nm process, brings 5,888 shading units, 184 texture mapping units, and 64 raster operation units to this pairing. Its 12 GB of GDDR6X memory operates across a 192-bit bus, delivering 504.2 GB/s of bandwidth. The GPU's boost clock of 2475 MHz and base clock of 1920 MHz contribute to its 29.15 TFLOPS of FP32 performance. In synthetic benchmarks, the RTX 4070 scores 26,927 in Passmark G3D and 154,858 in Geekbench OpenCL, with an 81st percentile ranking among all GPUs.

The GPU's influence on Microsoft Flight Simulator is clearly visible across the resolution and settings matrix. At 1080p Low, the system reaches 165 FPS, but this drops to 133 FPS at 1440p Low and 98 FPS at 4K Low. These reductions correlate strongly with pixel count: 4K has roughly 4.4 times the pixels of 1080p, yet the frame rate only drops by 41%. This non-linear scaling suggests that the GPU is not purely pixel-bound at Low settings; other factors such as draw calls and geometry processing play a role.

At Ultra settings, the GPU's workload becomes the dominant factor. The jump from 1080p Ultra (92 FPS) to 4K Ultra (55 FPS) represents a 40% reduction, and the 4K Ultra result of 55 FPS is the lowest measured average in the entire dataset. The RTX 4070's 12 GB frame buffer appears sufficient for 4K Ultra, as no out-of-memory artifacts or min FPS anomalies are recorded. However, the 55 FPS average at 4K Ultra is close to the edge of what might be considered smoothly playable for a flight simulator, where consistent frame times matter for immersion.

The GPU's nearest rivals, according to benchmark averages, include the NVIDIA Tesla P4 (0.1% delta), AMD Radeon RX Vega 56 (0.4% delta), and NVIDIA GeForce RTX 4080 Mobile (-1.3% delta). These comparisons show that the RTX 4070 sits in a specific performance tier, and the measured game results align with this positioning — it can handle 1440p High at 78 FPS and 1080p Ultra at 92 FPS, making it a capable mid-range option for this title.

Settings Recommendations

The measured FPS rows provide clear guidance on which preset offers the best experience. At 1080p, the Low preset delivers 165 FPS, which is well above the refresh rate of most monitors and provides headroom for frame drops. However, 1080p Medium at 128 FPS with a minimum of 109 FPS offers a more visually detailed experience while still maintaining high frame rates. The High preset at 96 FPS remains smooth, but Ultra at 92 FPS begins to approach the threshold where occasional dips could become noticeable in busy scenes.

At 1440p, the Medium preset stands out as the optimal balance. It produces 103 FPS average with a minimum of 88 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay. The High preset at 78 FPS is still playable, but the 25 FPS gap between Medium and High suggests that the extra graphical fidelity comes at a significant cost. Ultra at 74 FPS is marginally slower than High, indicating that the Ultra preset's additional effects do not penalize performance as heavily as the jump from Medium to High.

For 4K, the Medium preset at 76 FPS average with a 65 FPS minimum is the only configuration that consistently stays above 60 FPS. The Low preset at 98 FPS offers higher frame rates but sacrifices visual quality, while High at 57 FPS and Ultra at 55 FPS both dip below the 60 FPS threshold. Given that a flight simulator relies on smooth panning and detailed scenery, the Medium preset at 4K appears to be the sweet spot — it maintains playable frame rates while retaining enough graphical detail to appreciate the terrain.

Across all resolutions, the Medium preset provides the most consistent experience, with min FPS values that are 85-88% of the average. This consistency is crucial for a simulation where sudden frame drops can disrupt the experience. The Low preset offers the highest frame rates but at the cost of visual fidelity, while Ultra pushes the GPU to its limits without delivering proportionally better visuals.
