Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the combination of the Intel Core Ultra 5 225 and the NVIDIA GeForce RTX 3070 produces a clear picture of where its performance boundaries lie. The data shows a system that can deliver smooth, playable frame rates at 1080p and 1440p, but which begins to struggle when pushed to 4K with maximum settings. This pairing represents a balanced mid-range setup where the GPU becomes the primary bottleneck at higher resolutions, while the CPU provides a solid foundation capable of driving high frame rates at lower settings.

Resolution Scaling

The measured FPS data reveals a predictable and steep performance curve as resolution increases. At 1920x1080 with Low settings, the combo achieves an average of 135 FPS, which drops to 80 FPS at 3840x2160 with the same settings. This represents a 41% reduction in performance from 1080p to 4K, a substantial hit that underscores the GPU's workload scaling with pixel count. The trend continues across all settings; at Medium settings, the frame rate falls from 105 FPS at 1080p to 63 FPS at 4K, a 40% drop. At High settings, the decline is from 79 FPS to 47 FPS, a 40.5% reduction, and at Ultra settings, it goes from 75 FPS down to 45 FPS, a 40% decrease.

This consistent ~40% performance penalty when moving from 1080p to 4K indicates that the system is firmly GPU-limited at higher resolutions. The RTX 3070's rendering pipeline is being saturated by the increased pixel workload, and the scaling is nearly linear with the resolution increase. The fact that the percentage drop is so consistent across all settings levels suggests that the CPU is not the limiting factor at 4K; if it were, the performance gap between settings would be smaller, as the CPU would be the bottleneck regardless of graphical fidelity. The data shows a system where the GPU's compute and memory bandwidth are the primary constraints at 4K, while at 1080p, the frame rates are high enough to suggest the CPU is keeping pace effectively.

GPU Role

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture and features 8 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 448.0 GB/s. This memory configuration is a critical factor in Microsoft Flight Simulator's performance, as the game is known for streaming vast amounts of terrain and scenery data. The GPU's boost clock is rated at 1725 MHz, and its 5888 shading units deliver a peak FP32 performance of 20.31 TFLOPS. These specifications place the RTX 3070 in the 61st percentile of all GPUs, with a Passmark G3D score of 22214.

The VRAM capacity of 8 GB is a notable limitation for this game at 4K resolution. The benchmark data shows that at 3840x2160 with Ultra settings, the average FPS drops to 45, which is barely playable. This is likely due to the GPU hitting its memory capacity limit as it tries to load high-resolution textures, forcing the system to rely on slower data streaming. In contrast, the RTX 3070's nearest rival, the AMD Radeon RX 7600 XT, has a similar average benchmark score of 17083 versus 17208 for the RTX 3070, a delta of just 0.7%. However, the RTX 3070's performance in this game is more dependent on its memory subsystem, and the 8 GB frame buffer becomes a wall at 4K Ultra. The data indicates that while the GPU is capable at lower resolutions, its VRAM capacity is a bottleneck for the highest settings at 4K.

This places it in the upper-middle tier of all tested systems, indicating that it is a capable but not top-tier configuration for this specific game. The ranking reflects the balance between the two components; the CPU is a strong performer, but the GPU holds the combo back from achieving higher scores.

The CPU's overall benchmark average is 36938, which puts it in the 85th percentile of all CPUs. Its nearest rivals are the AMD Ryzen 5 5600F with an average score of 36945 (a delta of 0%), and the AMD Ryzen 5 5500X3D with a score of 37018 (a delta of -0.2%). This shows the Core Ultra 5 225 is essentially on par with these competing processors. The GPU, however, is in the 61st percentile, with an average score of 17208. The combination of a high-performing CPU and a mid-range GPU results in a combo rank that is skewed by the GPU's limitations. The data suggests that to improve this combo's rank, upgrading the GPU would yield a more significant benefit than upgrading the CPU, as the CPU is already performing at a high level relative to other components.
