Microsoft Flight Simulator

Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the AMD Ryzen 9 9900X and NVIDIA GeForce RTX 3050 4 GB reveals a steep performance cliff as resolution increases. At 1080p Low, the combo delivers 70.1 FPS, which drops to 56.2 FPS at 1440p Low and further to 39.1 FPS at 4K Low. That represents a 44% reduction in frame rate from 1080p to 4K at the lowest settings, indicating that the GPU is the primary constraint at higher resolutions.

The pattern intensifies with more demanding presets. At High settings, the frame rate falls from 40.2 FPS at 1080p to 31.7 FPS at 1440p, then to 22.3 FPS at 4K — a 45% drop from 1080p to 4K. The Ultra preset shows a similar trajectory: 38.6 FPS at 1080p, 30.5 FPS at 1440p, and 23.5 FPS at 4K. The gap between Medium and High at 4K is narrow (31.6 vs 22.3 FPS), suggesting that the GPU's memory bandwidth and capacity become increasingly limiting as pixel count rises.

What the data makes clear: this is not a CPU-limited scenario at high resolutions. The Ryzen 9 9900X with 12 cores and 24 threads is far more capable than what the RTX 3050 4 GB can feed at 4K. The diminishing returns between 1440p and 4K at Ultra (30.5 to 23.5 FPS) point squarely at the GPU's 4 GB VRAM and 192.0 GB/s bandwidth as the bottleneck. At 1080p, the frame rates are playable across all presets, but the moment resolution climbs, the GPU's limitations dominate the experience.

GPU Role

The NVIDIA GeForce RTX 3050 4 GB is the decisive component in this pairing. Its 4 GB GDDR6 memory on a 128-bit bus delivers 192.0 GB/s bandwidth, which is modest for a flight simulator that streams vast scenery data. The GPU's base clock of 1545 MHz and boost clock of 1740 MHz are standard for the Ampere architecture, but the real constraint is the memory subsystem. At 4K Ultra, the average FPS of 23.5 is barely above the 22.3 FPS at 4K High, indicating that the GPU is saturated regardless of the preset.

The RTX 3050 4 GB's 2048 shading units and 32 ROPs provide a theoretical FP32 throughput of 7.127 TFLOPS, yet the measured results show that raw compute is not the bottleneck — memory is. The 4 GB VRAM is likely exceeded by Microsoft Flight Simulator's texture streaming at 4K, causing the frame rate to crater. At 1080p Low, the 70.1 FPS result shows the GPU can handle the workload when memory pressure is low, but the 44% drop to 39.1 FPS at 4K Low is a clear signal that the GPU cannot maintain its performance as resolution scales.

The GPU's 90 W TDP and PCIe 4.0 x8 interface are not limiting factors in these results; the memory capacity and bandwidth are. The 4 GB frame buffer is the single most important specification here, and it directly explains why the 4K presets all fall below 40 FPS regardless of settings. The GPU's percentile rank of 50 versus all GPUs confirms it is a mid-range part, and the measured FPS data reinforces that it is outclassed by the CPU in this combo.

A: At 1080p Ultra, the measured average is 38.6 FPS, which is below the 60 FPS threshold. At 1440p Ultra, it drops to 30.5 FPS, and at 4K Ultra, it falls to 23.5 FPS. None of the Ultra presets reach 60 FPS.

How This Combo Ranks

The combo of AMD Ryzen 9 9900X and NVIDIA GeForce RTX 3050 4 GB ranks 1648 out of 1795 tested combinations in Microsoft Flight Simulator. This places it in the bottom 8% of all configurations, which is striking given the CPU's strength. The Ryzen 9 9900X sits in the 94th percentile versus all CPUs, with an average benchmark score of 54450. Its nearest rivals include the AMD Ryzen 9 9900X3D (avg score 54681, -0.4% delta), Intel Core i7-14700F (avg score 54097, +0.7% delta), Intel Core Ultra 5 245K (avg score 55304, -1.5% delta), and Intel Core Ultra 5 245KF (avg score 55421, -1.8% delta). The CPU is clearly not the issue.

The ranking is dragged down entirely by the GPU. The RTX 3050 4 GB holds a 50th percentile rank versus all GPUs, with no nearest rivals listed in the data. This mid-range GPU paired with a top-tier CPU creates a massive imbalance. The combo rank of 1648 reflects this mismatch: the CPU can handle the simulation's physics and flight model, but the GPU cannot render the scenery at acceptable frame rates, especially at higher resolutions. The benchmark results show that even at 1080p, the combo only achieves 70.1 FPS at Low settings, which is far below what the CPU alone could support if paired with a stronger GPU.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a complete picture of the combo's performance.

At 1920x1080, the results are:

• Low: 70.1 FPS
• Medium: 58.2 FPS
• High: 40.2 FPS
• Ultra: 38.6 FPS

The step from Low to Medium is a 11.9 FPS drop, Medium to High is an 18.0 FPS drop, and High to Ultra is only a 1.6 FPS drop. This suggests that the High and Ultra presets are both hitting a similar GPU ceiling, with the frame rate barely moving between them.

At 2560x1440, the results are:

• Low: 56.2 FPS
• Medium: 44.0 FPS
• High: 31.7 FPS
• Ultra: 30.5 FPS

The pattern repeats: Medium to High shows a 12.3 FPS drop, but High to Ultra is only a 1.2 FPS drop. The GPU is already saturated at High, and Ultra adds little additional load because the memory bandwidth cannot keep up.

At 3840x2160, the results are:

• Low: 39.1 FPS
• Medium: 31.6 FPS
• High: 22.3 FPS
• Ultra: 23.5 FPS

Notably, Ultra at 4K (23.5 FPS) is slightly higher than High (22.3 FPS), which is an anomaly. This indicates that the Ultra preset may be triggering different rendering paths or that the GPU is so memory-constrained that the settings differences become noise. The 4K results are uniformly below 40 FPS, confirming the GPU cannot handle this resolution.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is at 1080p with Low or Medium settings. Low delivers 70.1 FPS, which is smooth and responsive, while Medium drops to 58.2 FPS — still playable but closer to the 60 FPS threshold. High at 1080p falls to 40.2 FPS, and Ultra to 38.6 FPS, both of which are below the smooth-play threshold.

At 1440p, only Low (56.2 FPS) approaches playable frame rates. Medium at 44.0 FPS is borderline, while High (31.7 FPS) and Ultra (30.5 FPS) are too low for a smooth flight simulation experience. The data suggests that users should stick to 1440p Low if they want to stay above 50 FPS.

At 4K, all presets are below 40 FPS, with the best result being Low at 39.1 FPS. The 4K Ultra result of 23.5 FPS is essentially unplayable for a flight sim that requires precise control. Given the GPU's 4 GB VRAM, the recommendation is to avoid 4K entirely and prioritize 1080p Medium for a balance of visual quality and frame rate. The 58.2 FPS at 1080p Medium is the highest frame rate achieved at a non-Low preset, making it the best compromise.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge) on a 4 nm process. It has a base clock of 4.40 GHz, a boost clock of 5.60 GHz, and a 64 MB shared L3 cache. Its benchmark scores are exceptional: Cinebench R23 multicore reaches 46438, single-core 6555, and Geekbench multicore 19827 with single-core 3341. The CPU's 94th percentile rank versus all CPUs confirms its high-end status.

In Microsoft Flight Simulator, the CPU's role is to handle the flight model, weather simulation, and AI traffic. The 12 cores and 24 threads provide ample parallel processing, and the high boost clock of 5.60 GHz ensures strong single-thread performance, which is critical for the game's main simulation loop. The CPU's 3DMark scores — 13929 at max threads and 1286 at single thread — indicate it is not the bottleneck in this combo.

The measured FPS data supports this conclusion. At 1080p Low, the combo achieves 70.1 FPS, but this is likely GPU-limited even at this resolution, as the RTX 3050 4 GB's 50th percentile rank suggests it cannot push much higher. The CPU's nearest rivals, such as the Ryzen 9 9900X3D (avg score 54681, -0.4% delta) and Intel Core Ultra 5 245K (avg score 55304, -1.5% delta), are all within 2% of the 9900X's average score, meaning the CPU performance is competitive with the best available. The bottleneck is unequivocally the GPU, and pairing this CPU with a more capable graphics card would dramatically improve the in-game results, as evidenced by the combo's low rank of 1648 out of 1795.
