Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the benchmark results for the AMD Ryzen 9 9950X3D paired with the NVIDIA GeForce RTX 4090 show a system that is decisively powerful but whose performance scaling reveals a classic CPU-bound pattern at lower resolutions. The data indicates that this combination is ranked 21st out of 1795 tested combos, placing it in the top 1.2% of all configurations. The measured frames per second (FPS) across the board are exceptionally high, yet the relationship between resolution and performance provides clear insights into where the bottleneck lies.

Resolution Scaling

The progression from 1080p to 4K shows how the hardware load shifts between the processor and the graphics card. At 1920x1080 with Low settings, the system produces 232.4 FPS. Moving to 2560x1440 at the same settings drops the frame rate to 187.9 FPS, a reduction of 19.1%. The jump to 3840x2160 at Low settings results in 132.4 FPS, which is a further 29.5% drop from the 1440p figure. This steep decline as resolution increases is a classic indicator that the CPU is the limiting factor at 1080p; the GPU has spare capacity, but the processor cannot feed it data fast enough.

At the other end of the spectrum, the Ultra preset shows a different scaling behavior. At 1080p Ultra, the system achieves 127.9 FPS. At 1440p Ultra, it produces 104.6 FPS (an 18.2% drop), and at 4K Ultra, it falls to 75.9 FPS (a 27.4% drop from 1440p). While the percentage drops are similar to the Low preset, the absolute FPS values are much lower, suggesting that the GPU is now the primary constraint. The gap between the Low and Ultra presets at 4K is substantial: 132.4 FPS versus 75.9 FPS, a difference of 56.5 FPS. This indicates that at 4K, the RTX 4090 is working much harder, and the graphical fidelity settings have a significant impact on the final frame rate.

The 1440p data points are the most balanced. At High settings, the system delivers 112.2 FPS, which is only 24.9 FPS lower than the 1080p High result of 137.1 FPS. This relatively smaller drop suggests that the workload is more evenly distributed between the CPU and GPU at this resolution. The data shows that the system is not fully GPU-bound until reaching 4K, where the difference between the 1440p and 2160p results for the Medium preset (146.7 to 105.7 FPS) is a 41 FPS loss. This confirms that for users with high-refresh-rate 1440p monitors, this combination will often hit a CPU-imposed ceiling before the GPU maxes out.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It has a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The processor features a large 128 MB shared L3 cache, which is a hallmark of the X3D series and is particularly beneficial for simulation games that often have large, repetitive data sets. In synthetic benchmarks, it scores 1292 in 3dmark_single_thread and 17184 in 3dmark_max_threads, demonstrating strong performance across both lightly and heavily threaded workloads.

In the context of Microsoft Flight Simulator, the CPU's role is critical for physics calculations, flight model updates, and handling the complex scenery generation. The benchmark data highlights this importance. At 1080p with Low settings, the frame rate is 232.4 FPS. This is 100 FPS higher than the 4K Low result of 132.4 FPS. When the GPU is less burdened by pixel rendering at 1080p, the CPU's ability to process the game's simulation logic becomes the primary factor in achieving these high frame rates. The 16 cores and 32 threads ensure that the game's main thread and background tasks have ample resources, preventing stutters that can occur on lower-core-count processors.

The CPU's "3D V-Cache" technology, implied by the X3D moniker and the 128 MB L3 cache, is a distinct advantage here. While the benchmark data does not isolate the cache's effect, the overall CPU performance is strong enough to place this combo in the 96th percentile for all CPUs. The processor's nearest rival, the AMD Ryzen 9 9950X, has an average score of 70420, which is 1.8% lower. This suggests that the additional cache in the 9950X3D provides a measurable, if modest, edge in overall synthetic performance. The data indicates that the CPU is not a weak link at any resolution, but its influence on frame rates is most pronounced at 1080p, where the GPU has the most headroom.

Measured FPS Breakdown

The following data represents the measured average FPS for all tested combinations of resolution and settings.

1920x1080:

• Low: 232.4 FPS
• Medium: 182.4 FPS
• High: 137.1 FPS
• Ultra: 127.9 FPS

2560x1440:

• Low: 187.9 FPS
• Medium: 146.7 FPS
• High: 112.2 FPS
• Ultra: 104.6 FPS

3840x2160:

• Low: 132.4 FPS
• Medium: 105.7 FPS
• High: 78 FPS
• Ultra: 75.9 FPS

The data shows a consistent pattern: for each resolution, the Low preset provides the highest frame rate, followed by Medium, then High, with Ultra being the most demanding. The gap between settings is not uniform. At 1080p, the difference between Low and Medium is 50 FPS, while the difference between High and Ultra is only 9.2 FPS. This suggests that the Ultra preset at 1080p is not significantly more demanding than High in terms of raw FPS cost, but it still offers a lower frame rate. At 4K, the differences are more compressed. The gap between Low and Medium is 26.7 FPS, and the gap between High and Ultra is only 2.1 FPS. This compression indicates that the GPU is becoming saturated at 4K, and the incremental cost of higher settings is reduced because the system is already near its maximum rendering capability.

GPU Role

The NVIDIA GeForce RTX 4090 is a powerhouse based on the Ada Lovelace architecture. It features 24 GB of GDDR6X memory on a 384-bit bus, providing 1.01 TB/s of bandwidth. The GPU has a base clock of 2235 MHz and a boost clock of 2520 MHz. Its raw compute capabilities are enormous, with 82.58 TFLOPS of FP32 performance. This hardware is designed for high-resolution gaming and is among the most powerful consumer GPUs available.

The RTX 4090's performance in this game is clearly demonstrated at 4K. The fact that it can maintain an average of 75.9 FPS at 4K Ultra in a simulation title confirms its power. The GPU's role becomes more critical as resolution increases. At 1080p, the GPU is not the bottleneck, as evidenced by the high frame rates (232.4 FPS on Low). However, at 4K, the GPU's rendering workload grows exponentially, and the frame rates drop accordingly. The difference between 1080p Ultra (127.9 FPS) and 4K Ultra (75.9 FPS) is 52 FPS, which is directly attributable to the increased pixel count that the GPU must process.

The GPU's memory bandwidth and capacity are also important for a game like Microsoft Flight Simulator, which streams vast amounts of scenery and terrain data. With 24 GB of VRAM, the RTX 4090 is unlikely to be constrained by memory capacity, even at 4K with Ultra textures. The 1.01 TB/s bandwidth ensures that the GPU can quickly access these assets, preventing hitches. The GPU's percentile ranking of 91 places it well above its nearest rivals in the benchmark database, such as the NVIDIA Tesla T4 which has a deltaPct of -0.4, indicating the RTX 4090 scores 0.4% higher. This confirms that the RTX 4090 is a top-tier component, and its performance limits at 4K are more a reflection of the game's extreme demands than a deficiency in the card itself.

Settings Recommendations

The benchmark data provides a clear roadmap for optimizing the experience with this hardware. For users with 4K monitors, the Ultra preset is playable with an average of 75.9 FPS, which is smooth for a flight simulator. However, dropping to the High preset yields a marginal frame rate increase to 78 FPS, a gain of only 2.1 FPS. This suggests that for 4K, the Ultra preset is the better choice, as the performance cost for the highest visual quality is minimal. The data indicates that the system is GPU-bound at 4K, and the visual improvements from High to Ultra are relatively cheap in terms of performance.

For 1440p users, the High preset delivers 112.2 FPS, which is an excellent balance. Moving to Ultra reduces the frame rate to 104.6 FPS, a drop of 7.6 FPS. Given the high refresh rate potential of 1440p monitors, the High preset is recommended to keep frame rates above the 110 FPS mark. The Medium preset at 1440p offers 146.7 FPS, which is a significant jump, but the visual fidelity loss from High to Medium is often noticeable in a game that relies on detailed scenery. The High preset appears to be the sweet spot for 1440p.

At 1080p, all presets are playable, with even the Ultra preset achieving 127.9 FPS. The Low preset's 232.4 FPS is only useful for competitive or esports scenarios, which do not apply to a flight simulator. The data suggests that 1080p users should not hesitate to use the Ultra preset, as the CPU is the primary limiter here, and the GPU has ample headroom. The difference between High (137.1 FPS) and Ultra (127.9 FPS) is only 9.2 FPS, making the Ultra preset the clear recommendation for 1080p to maximize visual quality without a meaningful performance penalty.
