Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the combination of the Intel Core Ultra 5 225 and NVIDIA GeForce RTX 4070 Ti produces a dataset that clearly illustrates where the bottlenecks lie. The measured frames per second (FPS) across resolutions and settings reveal a system that is capable of excellent performance, but the scaling pattern indicates a shift in workload dominance as pixel count increases. This analysis walks through the measured results to interpret how the CPU and GPU each contribute to the final experience, and what the data suggests about optimizing settings for this specific pairing.

Resolution Scaling

The FPS data shows a predictable but telling decline as resolution increases from 1920x1080 to 3840x2160. At the "Low" settings preset, the average frame rate drops from 193 FPS at 1080p to 156 FPS at 1440p, and finally to 115 FPS at 4K. This represents a 40% reduction in frame rate from the lowest to the highest resolution, which is a substantial hit that points directly at the GPU becoming the primary limiting factor at higher pixel counts. The gap between 1080p and 1440p is 37 FPS, while the gap between 1440p and 4K is 41 FPS, showing a relatively consistent scaling penalty as the GPU is asked to render more pixels.

When moving to the "High" settings preset, the same trend is visible. The average FPS at 1080p is 113, which falls to 91 FPS at 1440p and then to 67 FPS at 4K. The percentage drop from 1080p to 4K here is approximately 41%, which is nearly identical to the drop seen at the Low preset. This consistency suggests that the resolution scaling penalty is independent of the settings preset, reinforcing the idea that the GPU's rendering throughput is the dominant constraint at higher resolutions, regardless of the visual complexity being processed.

The "Ultra" preset tells a similar story, with 1080p averaging 108 FPS, 1440p at 87 FPS, and 4K at 64 FPS. The absolute numbers are lower than the High preset, but the scaling behavior is consistent: a drop of 21 FPS from 1080p to 1440p, and a further drop of 23 FPS from 1440p to 4K. This pattern indicates that the RTX 4070 Ti's compute and memory resources are being saturated at 4K, and the performance ceiling at that resolution is firmly set by the GPU. The data implies that for users seeking the highest frame rates, 1080p or 1440p are the more appropriate targets, while 4K is viable but will necessitate a compromise on the settings preset to maintain smooth performance.

CPU Role

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor with a base clock of 3.30 GHz and a boost clock of 4.90 GHz. In the context of Microsoft Flight Simulator, which is known for heavy single-threaded simulation logic, the CPU's boost clock and architectural efficiency are critical. The benchmark data for this CPU shows a strong single-core performance, with a Cinebench R23 single-core score of 3655 and a Passmark single-thread score of 4412. These scores, along with a percentile rank of 85 against all CPUs, indicate that the processor has ample headroom to handle the game's simulation and physics calculations without becoming a major bottleneck at lower resolutions.

The evidence for this lies in the FPS scaling at 1080p. At the Low preset, the system achieves 193 FPS, which is a very high frame rate that suggests the CPU is capable of feeding the GPU with enough draw calls and simulation data to maintain high throughput. However, the delta between the Low and Ultra presets at 1080p is substantial, with Ultra dropping to 108 FPS. This 85 FPS gap is primarily due to the increased graphical load, but it also indicates that the CPU is not the limiting factor; if the CPU were the bottleneck, the frame rate would be more consistent across different graphics presets at the same resolution. The CPU's performance relative to its nearest rivals also supports this, as it sits within 0.5% of the AMD Ryzen 5 5600F and AMD Ryzen 5 5500X3D in average benchmark scores, showing it is a competitive mid-range part capable of sustaining high frame rates in this simulation.

The CPU's 20 MB of shared L3 cache and dual-channel DDR5 memory support with 102.4 GB/s bandwidth also contribute to its ability to handle the streaming world data that Flight Simulator requires. The Passmark data compression score of 302811 and integer math score of 65345 further demonstrate the processor's capability in handling the type of complex calculations that game logic demands. Overall, the data suggests that the Core Ultra 5 225 is a competent partner for the RTX 4070 Ti, providing sufficient processing power to avoid limiting performance at 1080p and 1440p, though the GPU becomes the clear limiting factor as resolution increases.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is the other half of this pairing, and its role in determining performance is much more pronounced at higher resolutions. The GPU features 12 GB of GDDR6X memory on a 192-bit bus, providing a bandwidth of 504.2 GB/s. Its base clock is 2310 MHz with a boost clock of 2610 MHz, and it contains 7680 shading units. The GPU's benchmark scores, including a 3DMark Steel Nomad DX12 score of 5024 and a Passmark G3D score of 31624, place it in the 84th percentile against all GPUs, indicating it is a high-end part with significant rendering muscle.

The measured FPS data makes the GPU's role clear. At 4K resolution, the frame rates are consistently the lowest across all settings, with the Ultra preset yielding an average of 64 FPS and the High preset at 67 FPS. This narrow gap between High and Ultra at 4K (only 3 FPS) suggests that the GPU is reaching its performance ceiling, and the additional visual features in the Ultra preset are having a minimal impact on the frame rate because the GPU is already fully utilized. In contrast, at 1080p, the gap between High and Ultra is 5 FPS (113 vs 108), which indicates the GPU has more headroom at lower resolutions.

The GPU's memory capacity of 12 GB is also a factor. At 4K with Ultra settings, the high-resolution textures and complex scenery likely consume a significant portion of the VRAM. The fact that the average FPS at 4K Ultra is 64, which is just below the 60 FPS target for smooth gameplay, suggests that the GPU is not only compute-bound but also potentially memory-bandwidth-limited. The data shows that the RTX 4070 Ti is a capable card for this game, but it is the primary determinant of performance at 4K, and users must adjust settings to achieve their desired frame rates at that resolution. The GPU's performance is also shown to be competitive, as its average benchmark score is within 1.6% of the NVIDIA RTX A6000 and -0.8% of the NVIDIA GeForce RTX 5090 Mobile, indicating it holds its own against other high-end options.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution and desired frame rate. At 1920x1080, the system is capable of running the "Ultra" preset with an average of 108 FPS, which is an excellent experience for a flight simulator that benefits from high visual fidelity. However, for players who prefer an even higher frame rate for smoother panning and camera movement, the "High" preset at 113 FPS offers a minimal performance gain over Ultra, making Ultra the better choice for visual quality at this resolution.

At 2560x1440, the "Ultra" preset still provides a playable 87 FPS, and the "High" preset at 91 FPS offers a slight edge. The data shows that the difference between High and Ultra at this resolution is only 4 FPS, so the Ultra preset is recommended for the best visual experience without a significant performance penalty. For 3840x2160, the situation is different. The "Ultra" preset drops to 64 FPS, which is on the edge of smooth gameplay, while the "High" preset is only marginally better at 67 FPS. The "Medium" preset, however, yields a more comfortable 89 FPS with a minimum of 76 FPS. Therefore, for 4K gaming, the "Medium" preset is the recommended choice to ensure a stable frame rate, as it provides a substantial performance boost over High and Ultra while still offering a reasonable level of visual detail.
