Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title that stresses both the CPU and GPU in ways few other games do. This analysis examines the Intel Core i7-12700K paired with the NVIDIA GeForce RTX 5090, a combination that sits at the 73rd position out of 3,714 tested combos, placing it in the top 2% of all configurations in our database. The benchmark results reveal a system that delivers exceptional frame rates across all resolutions, but the scaling patterns indicate that the CPU plays a pivotal role in determining the final experience.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-12700K is a 12-core, 20-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 3.60 GHz and a boost clock of 5.00 GHz, with a thermal design power of 125 W. Its cache configuration includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a 25 MB shared L3 cache. The processor supports dual-channel DDR4 and DDR5 memory, and its benchmark scores—such as a Cinebench R23 multi-core score of 19,784 and a single-core score of 1,850.5—demonstrate strong multi-threaded and single-threaded capabilities. It ranks in the 84th percentile among all CPUs, with an average benchmark score of 35,287.

In Microsoft Flight Simulator, the CPU's role is substantial due to the simulation's complex physics and world-streaming calculations. The data shows that at 1080p Low settings, the system achieves 212 FPS, which is the highest measured result in this configuration. This high frame rate at a CPU-heavy setting suggests that the i7-12700K is capable of feeding the RTX 5090 enough data to avoid a severe bottleneck. However, the difference between the 1080p Low score (212 FPS) and the 1440p Low score (192 FPS) is only 20 FPS, indicating that even at lower resolutions where the GPU has less work, the CPU is not the only limiting factor, but it begins to show its influence.

The processor's 20 threads are well-utilized by Flight Simulator, which benefits from multi-core performance for tasks like terrain generation and AI traffic. The Cinebench R20 multi-core score of 12,229 and the 3DMark 16-thread score of 9,276 suggest that the i7-12700K has ample headroom for these workloads. When compared to its nearest rivals, the i7-12700K is effectively tied with the Intel Core i5-13600T (average score 35,305, delta -0.1%) and the Intel Core i7-12700KF (average score 35,365, delta -0.2%). This places the CPU in a competitive position, though the RTX 5090's raw power means that in this specific pairing, the GPU is rarely the bottleneck in standard scenarios.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Examining the scaling across resolutions reveals a clear pattern of GPU-bound behavior at higher settings, but CPU sensitivity at lower ones. Starting with Low settings, the system delivers 212 FPS at 1080p, 192 FPS at 1440p, and 142 FPS at 4K. The drop from 1080p to 1440p is 20 FPS (a 9.4% decrease), while the drop from 1440p to 4K is 50 FPS (a 26% decrease). This larger drop at 4K indicates that the RTX 5090's rendering load becomes more significant, but the CPU still has enough headroom to maintain high frame rates.

For Medium settings, the results are 185 FPS at 1080p, 149 FPS at 1440p, and 110 FPS at 4K. The percentage drops are 19.5% from 1080p to 1440p and 26.2% from 1440p to 4K. This pattern suggests a more balanced workload, where both CPU and GPU are contributing to the performance ceiling. At High settings, the frame rates are 139 FPS at 1080p, 112 FPS at 1440p, and 83 FPS at 4K, with drops of 19.4% and 25.9% respectively. The consistency of these percentage drops across Medium and High settings indicates that the GPU is becoming the primary limiter as resolution increases.

Ultra settings tell a different story: 133 FPS at 1080p, 107 FPS at 1440p, and 79 FPS at 4K. The drop from 1080p to 1440p is 26 FPS (19.5%), and from 1440p to 4K is 28 FPS (26.2%). The fact that the 1080p Ultra score (133 FPS) is only 6 FPS lower than the 1080p High score (139 FPS) suggests that at this resolution, the CPU is still capable of pushing high frame rates, but the GPU's workload at Ultra settings begins to dominate. The data indicates that the RTX 5090 is the limiting component at 4K across all settings, as the frame rates drop proportionally with resolution, while the i7-12700K's influence is most apparent at 1080p where it maintains frame rates above 130 FPS even at Ultra.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i7-12700K and NVIDIA GeForce RTX 5090 achieves a rank of 73 out of 3,714 tested combos in Microsoft Flight Simulator.

When compared to other combos, this rank of 73 means there are 72 configurations that deliver higher average FPS across the tested settings. These are likely to include newer, higher-end CPUs paired with the same or similar GPUs, but the data shows that the i7-12700K does not significantly hold back the RTX 5090. The deltas between the CPU and its nearest rivals are minimal (all within -0.1% to -0.4%), suggesting that swapping to a slightly faster CPU would not yield substantial improvements in this game. The rank reflects the i7-12700K's strong multi-threaded performance, as evidenced by its Cinebench R23 multi-core score of 19,784, which allows it to keep up with the demands of Flight Simulator's complex simulation logic.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality presets. At 1920x1080, the system starts with a Low settings average of 212 FPS, which is the highest score in the entire dataset. Medium settings yield 185 FPS (min 158, max 213), while High settings produce 139 FPS. Ultra settings at 1080p deliver 133 FPS, showing a modest 6 FPS drop from High, indicating that the CPU is still capable of maintaining high frame rates even with the most demanding graphical preset at this resolution.

Moving to 2560x1440, the Low settings average is 192 FPS, which is a 20 FPS decrease from 1080p. Medium settings result in 149 FPS (min 127, max 172), and High settings produce 112 FPS. Ultra settings at 1440p achieve 107 FPS, which is only 5 FPS lower than High, suggesting that at this resolution, the GPU is beginning to become the limiting factor. The 1440p results show a clear scaling pattern, with each quality preset reducing the frame rate by a consistent margin.

At 3840x2160, the system delivers 142 FPS on Low settings, 110 FPS on Medium (min 94, max 127), 83 FPS on High, and 79 FPS on Ultra. The 4K results demonstrate that the RTX 5090 is fully utilized, as the frame rates are significantly lower than at lower resolutions. The difference between 4K High (83 FPS) and 4K Ultra (79 FPS) is only 4 FPS, indicating that the GPU is near its performance ceiling at this resolution. The min FPS of 94 at 4K Medium shows that even in demanding scenes, the system maintains a playable frame rate, though the variance of 33 FPS (between min 94 and max 127) suggests occasional frame time spikes.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings depend on the user's resolution and preference for visual fidelity versus frame rate. At 1920x1080, all presets deliver playable frame rates, but the Medium preset (185 FPS average, min 158) offers the best balance of smoothness and visual quality. High settings at 1080p (139 FPS) are also excellent, but the 46 FPS drop from Medium to High is significant, while the visual improvement may not be proportional. Ultra at 1080p (133 FPS) is only 6 FPS lower than High, so users seeking maximum visual quality can opt for Ultra without a major performance penalty.

For 2560x1440 users, the Medium preset (149 FPS average, min 127) is the recommended choice, as it provides a high frame rate that exceeds the refresh rate of most 1440p monitors (typically 144 Hz or 165 Hz). High settings (112 FPS) still offer a smooth experience, but the drop from Medium is 37 FPS, which may be noticeable in fast-moving scenes. Ultra at 1440p (107 FPS) is also viable, but the 5 FPS difference from High suggests that the GPU is becoming the bottleneck, and the visual gains from Ultra may not justify the reduced headroom.

At 3840x2160, the data indicates that Medium settings (110 FPS average, min 94) provide the best experience, as they maintain a frame rate above 90 FPS even during demanding moments. High settings (83 FPS) are playable but may exhibit occasional stutters, while Ultra (79 FPS) is still above 60 FPS but leaves little margin for frame rate drops. Low settings at 4K (142 FPS) offer the highest frame rate but sacrifice visual quality, which may be undesirable for a simulation game that relies on visual immersion. The recommendation is to prioritize Medium settings at 4K, as the combination of 110 FPS average and a min FPS of 94 ensures a consistently smooth experience without excessive graphical compromises.
