Microsoft Flight Simulator

The Intel Core i7-13700K paired with the AMD Radeon RX 9070 demonstrates a performance profile in Microsoft Flight Simulator that is heavily dictated by resolution scaling. At 1920x1080 with Low settings, the combination produces an average frame rate of 157.6 FPS. Moving to 2560x1440 at the same Low preset, the average drops to 125.3 FPS, representing a significant reduction. At 3840x2160 with Low settings, the average falls further to 93.2 FPS. This progression shows that even at the lowest graphical preset, the rendering load scales substantially with pixel count, indicating that the GPU is actively engaged across all tested resolutions. The delta from 1080p to 4K at Low settings is a drop of 64.4 FPS, which highlights that the Radeon RX 9070 has ample headroom at lower resolutions but becomes increasingly constrained as the pixel throughput demands grow.

When examining the High preset, the scaling pattern continues. The combo delivers 93.7 FPS at 1080p, 73.9 FPS at 1440p, and 53.4 FPS at 4K. The Ultra preset yields 84.6 FPS at 1080p, 68.7 FPS at 1440p, and 48.7 FPS at 4K. The performance drop from 1080p to 4K is most pronounced at the Low settings, where the frame rate is nearly halved. However, at Ultra settings, the drop is less severe in absolute terms, going from 84.6 FPS down to 48.7 FPS. This suggests that at higher settings, the workload becomes more balanced between the CPU and GPU, whereas at Low settings, the GPU is more likely to be the primary limiting factor as resolution increases. The data indicates that for users targeting 4K, the combination can still produce playable frame rates, but the preset choice becomes critical to maintaining smooth performance.

Resolution Scaling

The measured FPS data reveals a clear trend: higher resolutions consistently reduce average frame rates across all four settings presets. At the Low preset, the combination achieves 157.6 FPS at 1080p, which is the highest frame rate recorded in the entire dataset. This drops to 125.3 FPS at 1440p and 93.2 FPS at 4K. The scaling from 1080p to 1440p results in a 32.3 FPS loss, while the scaling from 1440p to 4K incurs a further 32.1 FPS loss. This near-linear scaling pattern suggests that the GPU’s rendering pipeline is the dominant factor at Low settings, with the CPU able to feed frames quickly enough to keep the GPU saturated.

At the Medium preset, the frame rates are 118.9 FPS at 1080p, 98.9 FPS at 1440p, and 67.8 FPS at 4K. The drop from 1080p to 1440p is 20.0 FPS, and from 1440p to 4K is 31.1 FPS. The larger drop at 4K indicates that the GPU is becoming more stressed as the pixel count increases, but the CPU still has enough headroom to maintain decent performance at the lower resolutions. For the High preset, the frame rates are 93.7 FPS at 1080p, 73.9 FPS at 1440p, and 53.4 FPS at 4K. This shows a consistent degradation, with the 4K result being nearly half of the 1080p figure. The Ultra preset follows a similar pattern, with 84.6 FPS at 1080p, 68.7 FPS at 1440p, and 48.7 FPS at 4K.

The data suggests that the limiting component shifts depending on the resolution and settings. At 1080p with Low settings, the high frame rate of 157.6 FPS indicates that the CPU is capable of driving the GPU to its limits. However, as resolution increases to 4K, the GPU’s workload becomes the bottleneck, with frame rates dropping to 93.2 FPS at Low and 48.7 FPS at Ultra. This is typical for a flight simulator, where the visual complexity of terrain and weather effects can heavily tax the GPU at higher resolutions. The combination of the Radeon RX 9070’s 16 GB of GDDR6 memory and 256-bit memory bus, providing 644.6 GB/s of bandwidth, helps mitigate some of the performance loss, but the sheer number of pixels at 4K still presents a significant challenge.

GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture and features 16 GB of GDDR6 memory on a 256-bit bus, yielding a memory bandwidth of 644.6 GB/s. The GPU has a base clock of 1330 MHz and a boost clock of 2520 MHz, with a game clock of 2070 MHz. These specifications position the card as a capable performer for flight simulation, where large textures and complex geometry require substantial memory capacity and bandwidth. The benchmark results show that the GPU’s performance in Microsoft Flight Simulator is strong, but not overwhelming, particularly at 4K resolutions.

The measured FPS data indicates that the GPU is the primary driver of performance at higher resolutions. At 4K with Ultra settings, the average frame rate is 48.7 FPS, which is below the 60 FPS threshold that many users consider optimal for smooth gameplay. This suggests that while the 16 GB VRAM is sufficient to hold the game’s assets, the raw compute power of the RX 9070 is taxed by the demands of 4K rendering. The GPU’s FP32 performance of 36.13 TFLOPS and pixel rate of 322.6 GPixel/s are high, but the complexity of flight simulation scenes, which often include dense terrain, dynamic lighting, and volumetric clouds, can still cause frame rates to dip.

Compared to its nearest rivals, the RX 9070’s average benchmark score of 34780 places it slightly behind the NVIDIA A2, which scores 34866, a delta of -0.2%. It is ahead of the NVIDIA Quadro GV100 by 0.3% and the AMD Radeon HD 7970 by 0.7%. This indicates that the RX 9070 performs at a level consistent with these other cards in synthetic benchmarks, but its real-world performance in Microsoft Flight Simulator is what matters for this analysis. The GPU’s 79th percentile ranking among all GPUs suggests that it is a solid mid-to-high-tier option, but not a top-tier enthusiast card. For users looking to play at 4K, the data shows that the GPU can handle the game, but compromises on settings may be necessary to achieve higher frame rates.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best experience for this CPU-GPU combination. At 1920x1080, the Low preset achieves 157.6 FPS, which is exceptionally smooth and likely exceeds the refresh rate of most monitors. The Medium preset delivers 118.9 FPS, which is still very fluid, while the High preset drops to 93.7 FPS, and Ultra falls to 84.6 FPS. For 1080p users, the High preset appears to be the sweet spot, as it provides a significant visual improvement over Medium while still maintaining a frame rate above 90 FPS. The Ultra preset’s 84.6 FPS is also playable, but the marginal visual gains over High may not justify the performance cost.

At 2560x1440, the Low preset yields 125.3 FPS, which is excellent for high-refresh-rate monitors. The Medium preset drops to 98.9 FPS, which is still very good, while High comes in at 73.9 FPS and Ultra at 68.7 FPS. For 1440p, the Medium preset offers the best balance between visual fidelity and performance, as it stays above 90 FPS while providing a noticeable upgrade over Low. The High preset at 73.9 FPS is acceptable for most users, but those who prioritize smoothness may prefer Medium. At 3840x2160, the Low preset achieves 93.2 FPS, which is surprisingly high for 4K, indicating that the CPU-GPU combo can handle the resolution with minimal settings. The Medium preset drops to 67.8 FPS, which is still playable, but High and Ultra fall to 53.4 FPS and 48.7 FPS, respectively. For 4K users, the Low preset provides the most consistent experience, while Medium is a viable option for those who want better visuals and can tolerate frame rates in the high 60s.

The data shows that the best experience depends on the user’s resolution and performance preferences. At 1080p, High settings provide a strong balance of quality and speed. At 1440p, Medium is the recommended preset, offering 98.9 FPS. At 4K, Low settings are the safest choice, with 93.2 FPS, but Medium at 67.8 FPS is also a reasonable option for users with VRR displays. The Ultra preset is only recommended for users who prioritize visual quality over performance, as it drops below 50 FPS at 4K.
