Microsoft Flight Simulator

Microsoft Flight Simulator with the Intel Core Ultra 7 265 and NVIDIA GeForce RTX 5090 delivers a top-tier experience, placing 38th out of 2996 tested combos. The data shows a system that is overwhelmingly GPU-bound at higher resolutions, while the CPU’s robust 20-core/20-thread configuration ensures that even at 1080p, frame rates remain exceptionally high. The benchmark results indicate that users can expect a smooth, highly detailed flight experience across all settings, with the most demanding Ultra preset still clearing 79 FPS at 4K.

Resolution Scaling

The performance drop from 1080p to 4K is significant but expected for a title like Microsoft Flight Simulator, which is known for its heavy graphical load. At Low settings, the average frame rate falls from 238 FPS at 1920x1080 to 142 FPS at 3840x2160, a reduction of roughly 40%. This scaling pattern is classic for a GPU-bound scenario at lower resolutions, where the RTX 5090’s immense power is the primary driver, and the reduction in pixel count directly translates to massive frame rate gains.

Moving to the High preset, the scaling is more linear. The average FPS at 1080p is 139, which drops to 112 at 1440p and further to 83 at 4K. This represents a 20% reduction from 1080p to 1440p and a 26% reduction from 1440p to 4K. The narrowing percentage gap as resolution increases suggests that the CPU begins to play a more significant role in limiting performance at higher resolutions, though the RTX 5090 remains the dominant factor.

The Medium preset shows a similar trend, with averages of 185 FPS at 1080p, 149 FPS at 1440p, and 110 FPS at 4K. The drop from 1080p to 1440p is 19%, and from 1440p to 4K is 26%. The Ultra preset, the most demanding, sees averages of 133 FPS at 1080p, 107 FPS at 1440p, and 79 FPS at 4K. Here, the scaling is nearly identical to High, with a 20% drop to 1440p and a 26% drop to 4K.

The data indicates that the limiting component shifts with resolution. At 1080p, the CPU’s strong single-threaded performance, evidenced by its Cinebench R23 single-core score of 5960, allows the GPU to run at full tilt, producing frame rates above 230 FPS at Low. At 4K, the RTX 5090’s rendering workload becomes the clear bottleneck, as the frame rates compress across all settings to a range of 79-142 FPS, showing less variance than at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 5090’s 32 GB of GDDR7 memory is a defining feature for Microsoft Flight Simulator. The game’s vast, streaming world benefits immensely from this capacity, allowing for extensive texture and geometry data to be held locally. The 1.79 TB/s of memory bandwidth ensures that this data can be fed to the GPU’s 21,760 shading units without stutter, which is crucial for maintaining smooth frame rates during fast descents or flybys over dense scenery.

The GPU’s clock speeds, with a base of 2017 MHz and a boost of 2407 MHz, are high, but the sheer scale of the chip is what sets it apart. With 170 RT cores and 680 tensor cores, the RTX 5090 is not just about raw rasterization; it’s equipped for future-proofing with advanced features. The benchmark results show that this hardware is more than capable of handling the game’s Ultra preset, which is the most demanding configuration.

The data suggests that the GPU’s role is paramount, particularly at 1440p and 4K resolutions. At 4K Ultra, the system achieves 79 FPS, a highly playable result. The fact that the 4K Low setting hits 142 FPS shows that the GPU has significant headroom, and any performance limitation at higher resolutions is due to the sheer number of pixels being rendered. The GPU’s Passmark G3D score of 39650 places it in the 92nd percentile of all GPUs, confirming its elite status.

In comparison to its nearest rivals, the RTX 5090’s average benchmark score of 79842 is 0.3% higher than the NVIDIA Tesla P100 PCIe 16 GB and 1.1% higher than the AMD Radeon RX 6850M XT. This marginal lead in synthetic benchmarks translates into the high real-world frame rates seen in this game, where the RTX 5090’s architectural advantages in memory bandwidth and shading power are fully utilized.

Settings Recommendations

For users aiming for the highest visual fidelity on a 4K display, the Ultra preset is the clear choice. The average frame rate of 79 FPS is above the threshold for a smooth experience, and the visual upgrade from High is substantial. The data shows that the gap between High and Ultra at 4K is only 4 FPS (83 vs. 79), making the performance cost of Ultra minimal relative to the visual benefit.

At 1440p, the Ultra preset also provides an excellent experience with an average of 107 FPS. This is a significant step up from the 4K result and allows for even smoother motion. For those who prioritize frame rate above all else, the High preset at 1440p offers 112 FPS, which is a negligible 5 FPS improvement over Ultra. Given this, there is no reason to choose High over Ultra at this resolution.

The Medium preset presents an interesting case. At 4K, it produces 110 FPS, which is 31 FPS higher than Ultra. This makes it an attractive option for users who want a high refresh rate experience on a 4K display and are willing to sacrifice some visual details. The 1440p Medium preset achieves 149 FPS, and the 1080p Medium preset hits 185 FPS. The data shows that Medium offers a substantial frame rate advantage over High and Ultra, making it the best choice for esports-style or competitive play, though this is less common in a flight simulator.

The Low preset is only recommended for users with high refresh rate monitors at 1080p, where it achieves a massive 238 FPS. At 1440p, it still provides an excellent 192 FPS. However, the visual fidelity loss is significant, and the data suggests that the system is so powerful that the Medium or High presets are preferable for the vast majority of scenarios, as they offer a much better balance of image quality and performance.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its peak performance. The Low preset averages 238 FPS, while Medium averages 185 FPS with a minimum of 158 FPS and a maximum of 213 FPS.
