Microsoft Flight Simulator

The AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4080 combination delivers a compelling, high-refresh-rate experience in Microsoft Flight Simulator, though the data reveals a clear shift in system bottleneck as resolution climbs. At 1080p, the pair is capable of frame rates exceeding 200 FPS on lower presets, while 4K Ultra settles into the 70 FPS range, indicating that the GPU becomes the primary limiting factor at higher pixel counts.

Resolution Scaling

The measured FPS data shows a pronounced and consistent drop as resolution increases from 1920x1080 to 3840x2160, which is expected for a flight simulator with heavy terrain and aircraft detail. At the High preset, the average frame rate falls from 123 FPS at 1080p to 99 FPS at 1440p, and finally to 73 FPS at 4K. This represents a 41% reduction from 1080p to 4K, a scaling pattern that strongly suggests the RTX 4080 is the dominant bottleneck at higher resolutions, as the CPU has more headroom to feed frames at lower pixel counts.

The scaling behavior becomes even more pronounced when examining the Low preset. At 1080p Low, the system achieves 211 FPS, which drops to 170 FPS at 1440p and 125 FPS at 4K. The absolute FPS loss from 1080p to 4K is 86 frames, which is a larger absolute drop than the High preset's 50-frame decline. This indicates that at Low settings, the GPU is still the limiting factor, but the CPU's role becomes more visible at 1080p where the 211 FPS ceiling is likely approaching the processor's maximum frame output capability.

The Medium preset offers the most complete data set, with min and max FPS values recorded for each resolution. At 1080p Medium, the average is 164 FPS with a min of 139 and max of 188. Moving to 1440p Medium, the average drops to 132 FPS with a min of 112 and max of 152. At 4K Medium, the average falls to 97 FPS with a min of 83 and max of 112. The delta between min and max FPS remains relatively consistent across resolutions, suggesting that frame pacing stability is maintained even as the average drops, which is a positive sign for gameplay smoothness.

The Ultra preset shows the most dramatic resolution sensitivity. At 1080p Ultra, the average is 117 FPS, which is only slightly below the High preset's 123 FPS, indicating that the CPU can still keep up at this resolution. However, at 1440p Ultra, the average drops to 95 FPS, and at 4K Ultra, it falls to 70 FPS. The 4K Ultra result of 70 FPS is the lowest measured average in the entire data set, and the scaling from 1080p to 4K shows a 40% performance loss, which is nearly identical to the High preset's scaling, confirming that the RTX 4080's rendering load is the primary constraint at 4K regardless of quality settings.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with a 5 nm process and features 16 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 716.8 GB/s. The GPU has a base clock of 2205 MHz and a boost clock of 2505 MHz, with 9728 shading units, 304 texture mapping units, and 112 raster output units. These specifications position the RTX 4080 as a high-end card, and its benchmark scores reflect this, with a 3DMark Steel Nomad DX12 score of 6567 and a PassMark G3D score of 34457.

In Microsoft Flight Simulator, the GPU's 16 GB VRAM buffer is more than sufficient for the game's texture and terrain data, even at 4K Ultra settings where the average FPS of 70 indicates the card is being pushed hard. The memory bandwidth of 716.8 GB/s is a critical factor for streaming high-resolution textures, and the data shows that the card maintains playable frame rates at all resolutions and presets, with the lowest average being 70 FPS at 4K Ultra.

The RTX 4080's nearest rival in the benchmark database is the NVIDIA GeForce RTX 4080 SUPER, which has an average score of 54209 compared to the 4080's 54247, a delta of just 0.1%. This indicates that the two cards are essentially performance equivalents in synthetic benchmarks, though the 4080 SUPER holds a slight edge in average score. The AMD Radeon Pro W5700X trails by 1.1%, while the AMD Radeon RX 6750 GRE 12 GB and AMD Radeon 8060S are 2.6% and 2.7% behind, respectively. These comparisons suggest that the RTX 4080 is well-positioned within its performance class, and the measured FPS data confirms that it delivers strong results in this flight simulator.

Settings Recommendations

Based on the measured FPS rows, the Medium preset appears to offer the best balance between visual quality and performance across all resolutions. At 1080p Medium, the system achieves 164 FPS with a tight min-max range of 139 to 188, which provides a smooth experience on high-refresh-rate monitors. At 1440p Medium, the average drops to 132 FPS with a min of 112 and a max of 152, still well above the 60 FPS threshold for fluid gameplay. Even at 4K Medium, the average of 97 FPS with a min of 83 and a max of 112 remains highly playable, making this preset the most versatile choice for users who prioritize frame rate consistency.

The High preset is a viable alternative for those seeking better visual fidelity, with 123 FPS at 1080p, 99 FPS at 1440p, and 73 FPS at 4K. While the 4K High result is below the Medium preset's 4K performance, it still clears the 60 FPS mark by a comfortable margin. However, the Ultra preset at 4K yields only 70 FPS on average, which is borderline for users with 60 Hz displays but may feel less responsive on 120 Hz or 144 Hz panels. For users with high-refresh-rate 4K monitors, the Medium preset is the recommended choice, as it provides a 27 FPS advantage over Ultra at the same resolution.

The Low preset is not recommended for this hardware combination, as it sacrifices too much visual quality for performance gains that are unlikely to be noticeable on displays capped at 144 Hz. At 1080p Low, the 211 FPS average exceeds the refresh rate of most consumer monitors, making the extra frames irrelevant. The data suggests that the Medium preset is the sweet spot, offering the best combination of visual detail and frame rate stability across all three resolutions.

The combination of the AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4080 ranks 215th out of 3714 tested combos in Microsoft Flight Simulator, placing it in the top 5.8% of all configurations in the database. This is a strong result for a pairing that features a 12-core, 24-thread CPU with a 128 MB L3 cache and a GPU with 16 GB of VRAM, confirming that this hardware combination is well-suited for the game's demanding simulation workload.

The rank of 215 out of 3714 indicates that there are 214 other combinations that achieve higher average FPS in this game, but the vast majority of tested systems fall behind this pairing. Given that the RTX 4080 sits at the 86th percentile among all GPUs and the Ryzen 9 9900X3D sits at the 91st percentile among all CPUs, the 215th rank is consistent with what one would expect from two high-performing components working together. The data shows that this combo is capable of delivering high frame rates at all tested settings, with the 4K Ultra average of 70 FPS being the only result that falls below the 100 FPS mark.

The rank also suggests that there is no significant bottleneck between the CPU and GPU in this game, as the combination performs in line with its component-level benchmarks. The CPU's nearest rivals, including the Intel Core Ultra 5 245KF with a delta of -0.6% and the Intel Core Ultra 5 245K with a delta of 1.3%, all have similar average benchmark scores, indicating that the Ryzen 9 9900X3D is competitive with other high-end processors in the same performance tier.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, manufactured on TSMC's 4 nm process. It has a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with a 128 MB L3 cache that is characteristic of the X3D series. The CPU's benchmark scores are impressive, with a Cinebench R23 multicore score of 47737 and a single-core score of 6739, placing it at the 91st percentile among all CPUs.

In Microsoft Flight Simulator, the CPU's role is most evident at 1080p resolution, where the frame rates reach 211 FPS on the Low preset. This high frame rate indicates that the Ryzen 9 9900X3D's single-thread performance, as evidenced by its 3DMark single-thread score of 1269 and PassMark single-thread score of 4646, is sufficient to feed the RTX 4080 at lower resolutions. The 12 cores and 24 threads also provide ample multi-threaded performance for the game's background simulation tasks, with a PassMark multithread score of 56154 and a Geekbench multicore score of 22884.

The CPU's 128 MB L3 cache is a significant advantage for flight simulators, which often require large amounts of fast-access memory for terrain and aircraft data. The data shows that the CPU maintains high frame rates even at 1080p Ultra, where the average of 117 FPS is only 5% lower than the High preset's 123 FPS, suggesting that the CPU is not a limiting factor even with maximum graphics settings. However, at 4K resolution, the CPU's influence diminishes as the GPU becomes the primary constraint, with the frame rate dropping by up to 41% from 1080p to 4K across all presets.

Measured FPS Breakdown
