Microsoft Flight Simulator

Microsoft Flight Simulator with an Intel Core i7-13700K and NVIDIA GeForce RTX 3080 is a high-end pairing that delivers playable frame rates across most settings, but the data reveals a clear performance ceiling at 4K Ultra. The combination ranks in the 69th percentile of tested systems (553rd out of 1795), placing it firmly in the upper tier of configurations, yet the measured results show that the RTX 3080's 10 GB VRAM and the CPU's 16 cores are both significant factors in how this simulator scales. The benchmark results indicate that this system is best suited for high-refresh-rate 1080p and 1440p gaming, while 4K requires a compromise on visual fidelity to maintain smooth flight.

CPU Role

The Intel Core i7-13700K provides substantial computational headroom for Microsoft Flight Simulator, which is a title known to be sensitive to single-thread performance. This processor features 16 cores and 24 threads, with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. In synthetic benchmarks, the CPU achieves a single-thread score of 1136 on 3dmark_single_thread and a multi-thread score of 12412 on 3dmark_max_threads, demonstrating its strength in both lightly-threaded and heavily-threaded workloads. The processor's 30 MB of shared L3 cache and 2 MB L2 cache per core help maintain data throughput for the complex flight dynamics and scenery streaming.

The CPU's impact on frame rates is most apparent at lower resolutions where the GPU is not the bottleneck. At 1080p with Low settings, the system reaches 159.2 FPS, which is the highest average recorded across all tests. This figure suggests that the 13700K, with its 5.40 GHz boost capability, can easily feed frames to the RTX 3080 at this resolution. The processor's 3dmark_8_threads score of 8193 and 3dmark_4_threads score of 4469 indicate robust performance in the mid-thread counts that games often utilize. Compared to its closest rivals, the 13700K is 0.1% behind the Intel Core i7-13700KF and 0.5% behind the AMD Ryzen 9 PRO 5945 in average benchmark score, but it is 0.3% ahead of the AMD EPYC 4364P and 0.4% ahead of the Intel Core i9-12900F. This places the CPU in the 93rd percentile of all processors, confirming its top-tier status.

GPU Role

The NVIDIA GeForce RTX 3080 is the primary driver of graphical performance, and its 10 GB of GDDR6X memory is a critical specification for Microsoft Flight Simulator. The GPU operates with a base clock of 1440 MHz and a boost clock of 1710 MHz, with memory running at 19 Gbps effective across a 320-bit bus, yielding a bandwidth of 760.3 GB/s. This memory bandwidth is essential for streaming high-resolution textures, but the 10 GB capacity becomes a limiting factor at 4K Ultra settings. The GPU's passmark_g3d score of 25086 places it in the 80th percentile of all GPUs, and its average benchmark score of 35787 is comparable to rivals like the AMD Radeon RX 7900 GRE, which is 0.9% faster, and the NVIDIA GeForce RTX 5070 Ti Mobile, which is 1% slower.

The GPU's role in the measured results is clear when examining the scaling from 1080p to 4K. At 1080p High, the system delivers 91.5 FPS, but at 4K High, the frame rate drops to 52.1 FPS, a reduction that highlights the GPU's workload. The 29.77 TFLOPS FP32 performance and 68 RT cores provide ample raw power, but the VRAM capacity appears to constrain the Ultra preset at higher resolutions. The RTX 3080's 10 GB memory is fully utilized in this scenario, as evidenced by the 4K Ultra average of 49 FPS, which is the lowest recorded in the dataset. The GPU's performance relative to its rivals suggests it is a balanced mid-to-high-end card, but not a top-tier 4K solution.

Settings Recommendations

The measured data shows that the High preset offers the best balance of visual quality and performance across all resolutions. At 1080p, the High preset achieves 91.5 FPS, which is smooth for a flight simulator, while the Medium preset delivers 123.2 FPS and Low delivers 159.2 FPS. At 1440p, High produces 71.8 FPS, which is playable, while Medium reaches 98.6 FPS and Low hits 126.9 FPS. At 4K, High drops to 52.1 FPS, which is marginal for a simulator that benefits from higher frame rates, but Medium holds at 71.1 FPS and Low reaches 92.9 FPS.

For users prioritizing visual fidelity, the Ultra preset is only viable at 1080p, where it achieves 85.8 FPS, and at 1440p, where it reaches 68.2 FPS. At 4K, Ultra falls to 49 FPS, which is below the threshold for a consistently smooth experience. The data suggests that High is the recommended preset for 4K gaming, as it provides a 6.3% improvement over Ultra (52.1 vs 49 FPS) while maintaining higher visual quality than Medium. For 1440p, High at 71.8 FPS is the sweet spot, as it offers a significant visual upgrade over Medium while staying above 60 FPS. At 1080p, High at 91.5 FPS is ideal for those with high-refresh-rate monitors, though Medium at 123.2 FPS is better for competitive play.

How This Combo Ranks

The combination of the Intel Core i7-13700K and NVIDIA GeForce RTX 3080 ranks 553rd out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 31% of all systems. This ranking reflects the balanced nature of the pairing, where the CPU's strong single-thread performance supports the GPU's substantial rasterization power. The combo's percentile ranking is consistent with the individual component percentiles: the CPU is in the 93rd percentile and the GPU is in the 80th percentile, suggesting that the system performs slightly below what the CPU alone would suggest, likely due to the GPU's VRAM limitations.

The measured frame rates align with this ranking. At 1440p High, the system achieves 71.8 FPS, which is a solid result for a demanding simulator. The data shows that the combo is more capable at 1080p, where it exceeds 85 FPS on all presets, and it becomes less competitive at 4K, where only Low and Medium presets maintain playable frame rates. This ranking indicates that the system is well-suited for 1440p gaming and can handle 4K with adjusted settings, but it is not among the elite configurations that can max out the Ultra preset at 4K.

Resolution Scaling

The frame rate drops from 1080p to 4K are substantial and reveal the limiting component in this system. At High settings, the average frame rate falls from 91.5 FPS at 1080p to 71.8 FPS at 1440p, a 21.5% decrease, and then to 52.1 FPS at 4K, a 27.4% further decrease. The total drop from 1080p to 4K is 43.1%, which is a significant reduction but not as severe as some other titles, indicating that the CPU still plays a role at lower resolutions.

The scaling pattern changes with the preset. At Low settings, the drop from 1080p (159.2 FPS) to 1440p (126.9 FPS) is 20.3%, and to 4K (92.9 FPS) is another 26.8%. At Ultra settings, the drop from 1080p (85.8 FPS) to 1440p (68.2 FPS) is 20.5%, and to 4K (49 FPS) is another 28.2%. The consistent ~20% drop from 1080p to 1440p across all presets suggests that the GPU is becoming the primary bottleneck at higher resolutions, as the pixel count increases by 77% but the frame rate drops by only 20%, indicating that other factors like CPU overhead are still relevant. At 4K, the larger drops (27-28%) confirm that the GPU is the limiting component, with the 10 GB VRAM likely causing the Ultra preset to suffer the most.

Measured FPS Breakdown

The measured data provides a complete picture of performance across resolutions and settings.

At 1920x1080, the system delivers the highest frame rates. Low settings achieve 159.2 FPS, Medium reaches 123.2 FPS, High produces 91.5 FPS, and Ultra yields 85.8 FPS. The difference between Medium and High is 25.7%, while the difference between High and Ultra is only 6.2%, suggesting that the Ultra preset offers diminishing returns at this resolution.

At 2560x1440, the frame rates remain playable but lower. Low settings hit 126.9 FPS, Medium achieves 98.6 FPS, High produces 71.8 FPS, and Ultra drops to 68.2 FPS. The gap between Medium and High widens to 27.2%, while High and Ultra are closer at 5.0% apart.

At 3840x2160, the system struggles to maintain high frame rates. Low settings reach 92.9 FPS, Medium achieves 71.1 FPS, High produces 52.1 FPS, and Ultra drops to 49 FPS. The difference between Medium and High is 26.7%, and High to Ultra is only 5.9%. The 4K results show that the Ultra preset is not viable, as it falls below 50 FPS, while High is marginal at just over 52 FPS.
