Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the AMD Ryzen 9 9900X and NVIDIA GeForce RTX 3060 Ti reveals a clear pattern: the game becomes increasingly GPU-bound as resolution climbs, but the CPU still plays a decisive role at lower settings. At 1080p Low, the combo averages 100.4 FPS. Dropping to 1440p Low reduces that to 81.6 FPS, a 18.8 FPS decline. At 4K Low, the average falls further to 57.4 FPS. This scaling from 1080p to 4K at Low settings represents a 43.0 FPS drop, indicating that even at the lowest graphical preset, the GPU is the primary limiter as pixel count quadruples.

However, the resolution scaling story changes dramatically when settings are raised. At 1080p Ultra, the average is 53.9 FPS. Moving to 1440p Ultra yields 45.1 FPS, and 4K Ultra sinks to 34.9 FPS. The delta between 1080p and 4K at Ultra is 19.0 FPS, proportionally smaller than at Low settings. This suggests that at Ultra presets, the game's heavy simulation workload and asset streaming place substantial demands on both CPU and GPU, with the RTX 3060 Ti’s 8 GB VRAM becoming a bottleneck at higher resolutions.

The most telling comparison is between settings at the same resolution. At 1080p, the spread from Low (100.4 FPS) to Ultra (53.9 FPS) is 46.5 FPS — the GPU is clearly the dominant factor. At 4K, the spread from Low (57.4 FPS) to Ultra (34.9 FPS) narrows to 22.5 FPS, meaning the GPU is so saturated that raising settings has less relative impact. In short, this combo delivers playable frame rates at 1080p across all presets, becomes marginal at 1440p with High and Ultra, and only approaches 60 FPS at 4K with Low settings.

How This Combo Ranks

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce RTX 3060 Ti achieves a combo rank of 1341 out of 1795 tested combinations in Microsoft Flight Simulator. This places the pairing in the 25th percentile of all combos tested — a modest result that reflects the GPU’s mid-range standing rather than the CPU’s strength. The CPU itself sits in the 94th percentile versus all CPUs, with an average benchmark score of 54450. The GPU, by contrast, holds only the 69th percentile versus all GPUs, with an average benchmark score of 25120.

The ranking indicates that while the 9900X is a top-tier processor, the RTX 3060 Ti drags the overall combo down in a flight simulator that is notoriously demanding on both components. The data shows a significant gap between the CPU’s potential and the combo’s actual in-game performance. Compared to other tested combos, this pairing lands in the lower-middle range, meaning many systems with weaker CPUs but stronger GPUs would outperform it in this specific title. The bottleneck is unambiguous: the GPU’s 8 GB VRAM and 16.20 TFLOPS of FP32 compute are the limiting factors, especially at 4K where the combo falls below 60 FPS on every preset except Low.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor from the 9000 series, built on the Zen 5 architecture (Granite Ridge) using a 4 nm process at TSMC. Its base clock is 4.40 GHz with a boost clock of 5.60 GHz. This CPU delivers exceptional multi-threaded performance, as evidenced by a Cinebench R23 multi-core score of 46438 and a single-core score of 6555. In 3DMark’s 16-thread test, it scores 12552, while max-thread performance reaches 13929. These numbers indicate the 9900X has ample headroom for Microsoft Flight Simulator’s simulation logic, which can leverage multiple cores for physics, weather, and AI traffic.

The 64 MB of shared L3 cache (1 MB L2 per core) provides substantial on-die storage for the game’s streaming world data. The CPU’s nearest rivals include the AMD Ryzen 9 9900X3D, which scores 54681 (only 0.4% higher), and the Intel Core i7-14700F at 54097 (0.7% lower). This places the 9900X in a tight performance band, meaning CPU choice among these options would have minimal impact on Flight Simulator FPS. The 9900X’s dual-channel DDR5 memory support with 89.6 GB/s bandwidth ensures the CPU can feed data to the GPU without starving it, but in this benchmark, the CPU is rarely the constraint. At 1080p Low, the combo reaches 100.4 FPS, but at 4K Ultra it falls to 34.9 FPS — a pattern that points squarely at the GPU as the performance ceiling.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings (Low, Medium, High, Ultra). At 1080p, the combo delivers 100.4 FPS on Low, 78.3 FPS on Medium, 57.4 FPS on High, and 53.9 FPS on Ultra. The step from Low to Medium is a 22.1 FPS drop, while the step from High to Ultra is only 3.5 FPS, suggesting diminishing returns at the highest preset. At 1440p, the averages are 81.6 FPS (Low), 60.7 FPS (Medium), 46.5 FPS (High), and 45.1 FPS (Ultra). The gap between High and Ultra narrows further to just 1.4 FPS. At 4K, the results are 57.4 FPS (Low), 47.1 FPS (Medium), 31.4 FPS (High), and 34.9 FPS (Ultra). Notably, at 4K, Ultra actually performs better than High by 3.5 FPS, which is within measurement variance but indicates that the Ultra preset may load-balance differently.

Across all settings, the largest single drop occurs from 1080p Low to 4K Low (43.0 FPS), while the smallest is from 1440p High to 1440p Ultra (1.4 FPS). The data shows that 60 FPS is achievable at 1080p with Medium or lower, and at 1440p with Low only. At 4K, no preset reaches 60 FPS; the best is Low at 57.4 FPS. For smooth gameplay at 60 FPS, users must stay at 1080p Medium or 1440p Low. The 100.4 FPS at 1080p Low indicates the combo can handle lighter loads, but anything above Medium at 1440p or any preset at 4K will drop below 50 FPS.

GPU Role

The NVIDIA GeForce RTX 3060 Ti is an Ampere-architecture GPU built on Samsung’s 8 nm process, with a GA104 chip containing 17,400 million transistors on a 392 mm² die. It features 4864 shading units, 152 TMUs, and 80 ROPs, with 38 RT cores and 152 tensor cores. The GPU’s base clock is 1410 MHz with a boost of 1665 MHz, delivering 16.20 TFLOPS of FP32 compute. Memory consists of 8 GB of GDDR6 on a 256-bit bus, providing 448.0 GB/s of bandwidth. The pixel rate is 133.2 GPixel/s and texture rate is 253.1 GTexel/s.

In Microsoft Flight Simulator, the GPU’s 8 GB VRAM is a critical constraint. At 4K with High settings, the combo averages just 31.4 FPS, and even at 1080p Ultra it only reaches 53.9 FPS. The GPU’s average benchmark score of 25120 places it near the AMD Radeon RX 6700M (25180, 0.2% higher) and the RX 6600 (25235, 0.5% higher). This tight clustering means the RTX 3060 Ti performs almost identically to those rivals in synthetic tests, and the in-game data reflects this mid-range standing. The 448.0 GB/s bandwidth is sufficient for 1080p but becomes a bottleneck at 4K, where the game streams high-resolution textures and terrain data.

The GPU’s 69th percentile ranking versus all GPUs understates its role in this combo; the CPU is far stronger (94th percentile). The measured FPS shows that at 4K Low, the GPU still delivers 57.4 FPS, but at 4K Ultra it drops to 34.9 FPS — a 22.5 FPS penalty for raising settings. This demonstrates that the RTX 3060 Ti’s compute and memory bandwidth are the limiting factors in this pairing, not the Ryzen 9 9900X.

Settings Recommendations

For users targeting 60 FPS, the only viable presets are 1080p Medium (78.3 FPS) or 1440p Low (81.6 FPS). At 1080p, High (57.4 FPS) and Ultra (53.9 FPS) fall short of 60, so Medium is the best balance of visual quality and performance. At 1440p, Low is the sole preset above 60 FPS; Medium (60.7 FPS) is technically playable but marginal, while High (46.5 FPS) and Ultra (45.1 FPS) are not recommended for smooth gameplay.

For users willing to accept 30-50 FPS, 4K Low (57.4 FPS) is the only option near 60, while 4K Medium (47.1 FPS) provides a more detailed experience. 4K High (31.4 FPS) and Ultra (34.9 FPS) are not recommended due to sub-35 FPS averages. The data shows that High and Ultra settings yield nearly identical performance at 1440p (1.4 FPS difference) and 4K (3.5 FPS difference, with Ultra actually faster), so selecting Ultra over High is a free visual upgrade in those cases.

The optimal experience per the measured rows is 1080p Medium, which delivers 78.3 FPS — comfortably above 60 — while still offering meaningful visual fidelity over Low. Users with 1440p monitors should choose Low (81.6 FPS) or Medium (60.7 FPS) depending on their tolerance for frame rate dips. At 4K, the combo is best reserved for Low settings (57.4 FPS) if playability is the priority. The RTX 3060 Ti’s 8 GB VRAM is the limiting factor, so avoiding Ultra textures at 4K is advisable based on the measured data.
