Microsoft Flight Simulator

Microsoft Flight Simulator presents a unique challenge for hardware analysis, as its workload shifts dramatically between CPU-bound terrain streaming and GPU-bound rendering. This data set, measured with the Intel Core i7-14700KF and NVIDIA GeForce RTX 4070, provides a clear picture of how this combination handles the simulator’s demands across three resolutions and four quality presets. The results show a configuration that is capable of high refresh rates at 1080p but becomes increasingly GPU-limited as resolution scales, making the choice of settings crucial for a consistent experience.

Resolution Scaling

The measured frame rates reveal a classic scaling pattern, with performance dropping steeply as pixel count increases. At 1080p, the system delivers a robust 165 FPS on Low settings, but this falls to 98 FPS at 4K on the same preset — a reduction of roughly 41%. This significant drop indicates that even at Low settings, the GPU is becoming a bottleneck as resolution increases, though the CPU’s high core count and boost clock are sufficient to feed the frame pipeline at lower pixel counts.

The scaling becomes more pronounced at higher settings. Moving from 1080p to 4K on High settings yields a drop from 96 FPS to 57 FPS, a 39 FPS decrease. On Ultra settings, the transition is even steeper, with frame rates falling from 92 FPS at 1080p to just 55 FPS at 4K. This pattern strongly suggests that the RTX 4070’s 12 GB of VRAM and 192-bit memory bus are sufficient for 1080p and 1440p gaming, but at 4K, the rendering load — particularly with High and Ultra presets — overwhelms the GPU’s compute and memory bandwidth, creating a definitive GPU-bound scenario.

The medium preset provides the most illustrative data for scaling analysis, as it is the only setting with recorded minimum and maximum frame times. At 1440p, the medium preset averages 103 FPS with a minimum of 88 FPS, while at 4K, the average drops to 76 FPS with a minimum of 65 FPS. This 27 FPS average reduction between 1440p and 4K, coupled with the minimum frame rate falling below 70 FPS at 4K, indicates that the GPU is the limiting component at higher resolutions. The CPU, with 20 cores and 28 threads, is unlikely to be the primary constraint in this scenario, as its workload does not scale linearly with resolution.

Examining the low preset scaling further reinforces this conclusion. The 1080p Low result of 165 FPS suggests the CPU can push well beyond typical monitor refresh rates, but the 4K Low result of 98 FPS shows that the GPU’s fill rate and shading capabilities are the ceiling. The data indicates that for players targeting 4K, the RTX 4070 will provide playable frame rates, but the experience is heavily dependent on settings, with Low offering a comfortable margin above 60 FPS and Ultra sitting precariously close to that threshold.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience with this combination. At 1080p, the Ultra preset delivers 92 FPS, which is only 4 FPS lower than High’s 96 FPS. This small delta makes Ultra the recommended choice for 1080p users, as the visual fidelity gains come at a negligible performance cost. The Medium preset at 128 FPS offers a substantial boost for competitive or high-refresh-rate play, but the gap between Ultra and High is so small that there is little reason to drop below Ultra unless chasing maximum frame rates.

At 1440p, the decision becomes more nuanced. The Ultra preset achieves 74 FPS, which is above the 60 FPS playability threshold but not by a large margin. High settings produce 78 FPS, a modest improvement, while Medium jumps to 103 FPS. For a flight simulator, where smoothness is often prioritized over absolute fidelity, the medium preset appears to be the sweet spot, offering a 29 FPS improvement over Ultra while still maintaining a high level of visual quality. The recorded minimum of 88 FPS on Medium at 1440p ensures that even complex scenes with dense terrain or weather effects will stay smooth.

At 4K, the settings recommendation becomes critical. The Ultra preset yields 55 FPS, which falls below the 60 FPS target and may result in noticeable stutter in demanding scenarios. High settings improve this to 57 FPS, still marginally below target. The Medium preset, however, provides 76 FPS with a minimum of 65 FPS, making it the clear choice for 4K play. Low settings at 98 FPS are available for those who prioritize frame rate above all else, but the visual compromise is significant. Based on the data, the Medium preset at 4K offers the best balance of visual quality and smooth performance, with the minimum frame rate staying above the 60 FPS threshold.

GPU Role

The NVIDIA GeForce RTX 4070 plays a central role in these results, and its specifications directly explain the observed scaling behavior. The GPU features 12 GB of GDDR6X memory on a 192-bit bus, providing 504.2 GB/s of bandwidth. This configuration is well-suited for 1080p and 1440p gaming, but at 4K, the memory bandwidth becomes a limiting factor, particularly with higher quality presets that increase texture and buffer sizes.

The RTX 4070’s clock speeds are notable, with a base clock of 1920 MHz and a boost clock of 2475 MHz. These high clocks contribute to its strong performance at lower resolutions, where the GPU can maintain high utilization without memory bandwidth constraints. The 5888 shading units and 64 ROPs provide ample compute for the simulator’s rendering tasks, but the 4K results suggest that the GPU’s overall throughput is insufficient for Ultra settings at that resolution.

The VRAM capacity is adequate for this game, as the data does not show catastrophic frame rate drops that would indicate memory overflow. However, the 4K Ultra result of 55 FPS, compared to the 4K Medium result of 76 FPS, suggests that the increased memory pressure and compute load from higher-quality textures and effects are the primary drivers of the performance gap. The GPU’s 200 W TDP and dual-slot design indicate a power-efficient architecture, but the Ada Lovelace architecture’s strengths are more evident at lower resolutions where the GPU is not saturated.

Measured FPS Breakdown

The complete set of measured frame rates reveals a consistent hierarchy across resolutions. At 1080p, the Low preset delivers 165 FPS, Medium provides 128 FPS with a minimum of 109 FPS, High achieves 96 FPS, and Ultra produces 92 FPS. The progression from Medium to High to Ultra shows diminishing returns, with only a 4 FPS difference between High and Ultra, suggesting that the CPU is beginning to become a factor at these high frame rates.

At 1440p, the results are more evenly spaced. Low settings produce 133 FPS, Medium averages 103 FPS with a minimum of 88 FPS, High reaches 78 FPS, and Ultra settles at 74 FPS. The gap between High and Ultra narrows to 4 FPS, mirroring the 1080p pattern, while the gap between Medium and High widens to 25 FPS. This indicates that the transition from Medium to High introduces a significant rendering cost, likely due to increased shadow quality, texture filtering, and other visual effects.

At 4K, the frame rates compress significantly. Low settings achieve 98 FPS, Medium averages 76 FPS with a minimum of 65 FPS, High produces 57 FPS, and Ultra drops to 55 FPS. The difference between High and Ultra is just 2 FPS, showing that the GPU is saturated at this resolution, and further visual enhancements have minimal additional cost because the GPU is already at its limit. The Medium preset’s minimum of 65 FPS is the only 4K result that remains comfortably above the 60 FPS threshold, reinforcing its status as the recommended setting for this resolution.
